My beloved treasure

Chapter Text


" Thank you for your kindness lord Hou "


" Thanks for your concern master Hou" 


" Long live Hou ye "


A group of maids is standing in front of the huge wooden gates of the old marquis mansion while endlessly appreciating their master's kindness with sugar-coated words.

They all have received a week-long holiday for the lunar new year this time but their master didn't let them go to their houses empty-handed. He gave them 10 tails of gold each and a bag of rice as a new year's gift. So it's needless to say that they are more than happy. 


" Okay okay, everyone. Are you all planning to stand here until new year's day arrives?. Now quickly move before the sun goes down. Your children must be waiting for you" 


After the noisy group left the mansion, Gu Yun, the master of the mansion, well known as the Supreme coach of the four realms leisurely walks into the house only to be met with the pair of annoyingly sharp eyes of his childhood friend shen yi. 


"What are you looking at?. Just take that home-brewed wine bottle out rascal" 


Shen Yi hides the bottle in his sleeve before Gu Yun gets the chance to snatch it away from him. 


"you can't just drink this. As my father said, this is a strong liquor. I barely managed to ask for a bottle from him without getting a one hour long lecture. Also, where's chang geng?. I didn't see him anywhere. If he went to the palace, then it's good for him. Otherwise, he'll have to witness your drunken stupor." 


With the mention of Chang Geng's name, Gu Yun's dim eyes suddenly lit up but his voice sounds calm as ever, not wavering one bit. 


" That boy is still here. He's been hiding in his room ever since he presented as alpha and hasn't come out except for morning classes and dinners." 


"That means he has been in his room for more than a month now...hmmm...wait!!"


Shen Yi smells something fishy as he thinks about Gu Yun's words and suddenly a disturbing thought pops into his mind. 


" Gu Zi Xi. Don't tell me you haven't taken your suppressants this time. Even though you have been controlling your hormones for years, you still can't completely lay your trust in yourself. Besides he is an alpha, on top of it all the 4th prince. Nothing bad can happen to him under our watch."


Gu Yun smacks shen yi's head with the back of his hand the moment he finishes his long speech. 


Just exactly what this guy is thinking about him?. 


"Are you stupid? I am the commander of Great Liang. I have been fighting on the battlefield and eating sand in the northwest every day yet, just how many people know that I am an omega?. I have been carefully keeping this secret to myself for so long so how in the world could I forget to hide it from Chang Geng as well?. I am not that irresponsible."


"Anyway just give me the damn bottle without wasting my precious time. "


Soon the two of them start to fight for the shots under the moon and the bottle is finished even before they get completely wasted.


"Just how small this bottle is?. I can't even feel the thrill in my nerves. What sort of shit is this?." 

Gu Yun shakes the bottle into his opened mouth, in the hope to catch the very last drop since his life motto just so happens to be "wasting even a single drop of wine is a sin" 


"Shit. Did you say shit????. That wine was personally brewed by the old man... Of... Of my family. You... You crow mouth, stop insulting him." 


Seeing that his fool of a friend is getting tipsy so quickly, the marquis can't help but sneer. 


"huh, you are an alpha but already drunk by this much??. Ji ping, you truly let me down as your friend" 


"Whaaat.. What did you say? " 


After riling up the poor man, he is more than prepared to pick up a fake fight with him for some fun when.... 




The sound of something crashing to the ground shakes the entire mansion, followed by a rushed noise of someone running around with heavy footsteps. 


Gu Yun feels restless. Who is this? Is this some kind of a bugler or a sneaky little rat trying to rob from his kitchen? Whether it's a rat or a man, no one gets to survive if they dare to steal from the marquis manor. 


With this thought in mind, Gu Yun walks into the kitchen to find the small thief but all he sees is a clay pot smashed into pieces on the floor and a figure of a teenage boy dressed in a pale white robe standing awkwardly in a corner while staring at him with his deer-like round eyes. 


"Chang geng. What are you doing here?." 


Gu Yun walks to the startled boy on the difficult path which has clay pieces scattered all over.

He scans Chang Geng's face for any signs of discomfort, but he can't find anything because this boy is so excellent at disguising his emotions and displaying fewer expressions.

"I am asking again. Why did the little prince make a mess in my kitchen? Did something happen?." 


"N... No"


Chang Geng finally lifts his head to stare deep into his yifu's sinister eyes and shows a dull smile. He looks somewhat embarrassed but Also a bit shy to admit what he was doing here in the middle of the night. 


"I umm. I.... I was trying to make some noodles for yifu." 


Gu Yun almost spits out the last cup of wine he drank a few moments ago. 

Making noodles, for him.. this late..??? 

"Why did your Highness want to cook noodles for me out of nowhere?. I don't remember asking for a favor like that. Also, your Highness doesn't need to lower yourself that down to do labor work for someone like me. How can I show my face to your brother if your Highness keeps on doing these kinds of things?. "


Gu Yun finally pulls out the" your highness card ".When he does that, chang geng is always in excruciating pain. Whenever his yifu addresses him as Yan Wang, or highness, he feels as though they are hundreds of miles apart and that no matter how fast he runs, he will never be able to reach him. He doesn't want to be a complete stranger to this Gu Yun. All he wants is to be as close to him as possible until he passes away.

"It's just that I thought you were drunk and haven't eaten. It's not good to sleep with an empty stomach, especially after you drink strong wine. You'll eventually have digesting problems and I don't want that to happen. " 


Isn't this boy so good at lecturing him? No matter how much Gu Yun despises to hear others advising him to change his extremely messed up lifestyle, whenever Chang geng does that, he feels sincerely happy. It's like the feeling of having someone in the home waiting for him, having someone to take care of him and worry about him every day. It's honestly a wonderful feeling.


Marshal Gu has never experienced what other omegas have to go through. Whether it was endless hardships of running away from possessive alphas or endless sweet little moments of living together with their husbands and kids or lovers, Gu Yun has never had these experiences but at some point, he did not chase after the only thing he has ever missed in his life. 




This word didn't seem to exist in his limited vocabulary but as an omega himself, he can not help but admit that sometimes when he is with Chang geng, because this child is always caring and very genuine to him, he too feels the need to be loved by someone. To be held by someone and to have a family of his own with someone. Chang Geng makes him crave love for some odd reason. 

Gu Yun closes the distance between them step by step until he is only an inch away from Chang Geng's face. This young boy has recently hit his growth spurts like a baihong arrow hits an enemy's armor with great force.


He's already a head taller than Gu Yun, so he has to look up at him at moments like this to gaze into his beautiful brown eyes.


"so thoughtful. Aren't you better than a wife? I don't think that even my future wife will care about me as much as your Highness does." 


He does not know whether it's because the alcohol in his blood is starting to act up or because of how moved he is by Chang Geng's gentle behavior. Nevertheless, he spits those words out without thinking, making a thin layer of pinkish blush appear on the top of the young boy's cheeks. 

How cute


"Yifu, wait here. I will be quick and make something for you" 


In the end, it is nothing more than a simple bowl of rice noodles and a fried egg on top but Gu Yun digs in happily like he is eating his first meal after days of starving. Chang geng smiles at the sloppy way his yifu eats from a distance. 

"How does it taste?." 


Chang geng remembers to ask because if he has any flaws this time as well, he knows he must do better for his yifu the next time.


"not bad but not too good either. Just fine and it is to my taste. Thank God you don't add eggshells to your food as an extra flavor anymore. hahaha" 


After Gu yun eats his meal he waits for chang geng to finish washing the dishes in the kitchen before he subconsciously falls asleep. 



When he wakes up, he is already lying on his bed in his room. He gets up and looks around. He does not remember anything like walking into his room last night or sending shen yi home but he was sleeping when he got up. Even the thin curtains of his bedside window have drawn together, blocking the sun from hitting his face. He always forgets to do this and wakes up early. So it must be Chang geng who carried him into his room because otherwise there's no other person in this isolated place who can be more thoughtful than him. 


he remembers that last night, he felt like he is floating on clouds and it was not that he was just floating on clouds but that he was being carried in Chang Geng's strong arms to his own room. Not only that, the most terrific part is that he remembers he was so happy in his dreams because he gave a kiss to a maiden and it felt so real. He can still feel the soft and warm touch of that person's lips and it was none other than his own adoptive son Chang geng who was kissed by him last night. He could sense the faint smell of tranquilizer on Chang Geng's body but he was too drunk to tell people apart. That liquor hit late as Shen yi said, he must accept that bitter truth even if it's too late now. 


He feels hot all of a sudden. small beads of sweat start to form on his forehead, slowly trickling down the sides of his face. It's not even a particularly hot day, to begin with, yet he is constantly burning up from head to toe.


"Wha....what is wrong with my body?."


For the first time in his 25 years of life, marshal Gu gets confused to the point that he can't even breathe. He first thought that he is simply having a fever but now he is not only burning up but also having difficulties in breathing. He sucks the air from his mouth since he doesn't know what else to do at the moment.

It takes him more than 10 minutes to notice that his lower body is wet. He quickly pushes the quilt aside and pulls his pants down. He can't believe his own eyes. A transparent liquid seems to be running down his thighs. The unfamiliar liquid smells like honey and milk.

Wait honey and milk.????


isn't that the unique smell of his pheromones?. What the heck is happening to him?.


As an omega who hasn't gone through a single heat in his entire life, Gu Yun is truly confused. Needless to say that he has never seen his own slick. He did have this doubt in a corner of his mind but he didn't pay any attention to it as he was afraid to accept the truth.....that....that he is in his first heat until his scent glands began to release pheromones wave after a wave.


"OH lord noooooooooooooo......!!!!"


"Hou dan....Hou dan!!!!!!!"


He tries to call out Hou-dan's, his most trusted old servant's name to no avail since he was also sent home personally by him. He is such a fool. Hou-dan didn't even want to go home but gu yun constantly nagged him to go and see his grandchildren in the new year, so much so that in the end hou-dan had no choice but to obey Gu Yun's demand. If he was there, Gu yun would have simply asked him to buy some suppressants and wait. After he drank the suppressants, the heat would slowly fade away and all he needed to do was sleep until he was feeling all fine once again. However, this time it's not the case. He is all alone in the mansion...wait!!!


Chang geng is also in the mansion, isn't he?.


Gu Yun sweeps that thought away the moment it comes into his mind. Gu Yun has a thick face and he can't lose it no matter what. He hasn't revealed his second gender to the boy yet and he is reluctant to do so. The only option he has is to walk down the street and buy the suppressants himself from that old doctor but.........

How???. His glands are already spraying pheromones like crazy. If he steps outside in a state like this, he'll attract all the attention. The entire town knows him as Anding Hou and his true identity as an omega will also be revealed overnight just like that. Therefore everyone will only see him as a weak omega. He will never be able to face anyone. Never be able to lead the black iron camp's troops in any war in the future. 

Furthermore, he doesn't have any faith in himself now. He was so sure that he would never have a heat as long as he takes medicine but it was proven to be wrong in front of his own eyes. So who takes the blame if he loses his mind in the middle of the town and lets some random alpha mark him?. He'll have to suffer for a lifetime.

At this point, the only thing he can do is lie on the bed and wait patiently until his heat passes away but for how many days???. He once heard that it takes more than a week to last.


He is panicking so much. If he is truly in his heat, although he is still mentally very stable and can control his emotions, he knows that once an intense wave of heat hits him, he is going to be over. Not to mention that the first heats of the omegas are always very painful, especially when you are unmated and don't even have an alpha beside you to soothe you with his pheromones. Gu yun will definitely not be able to go through that kind of torture alone. 


Now Gu Yun has only one option to choose between two.

one is, putting his life at stake and going outside to buy medicine. Two is going to chang geng and plead him to release some calming pheromones until he arrives with medicine.


After all chang geng is an alpha, a young alpha at that too. His pheromones must be strong enough to suppress the omega instincts and it will only lead him to the good.

Thus he chooses the second option.

He rises to his wobbling feet and drags himself out of his room to the long long corridor. He hates himself for not picking chang geng's room near to his own in order to prevent something inappropriate from happening but in the end, isn't he the one stumbling towards the said adoptive son's room to ask for an inappropriate offer?.


How very laughable.?


As he walks farther down the corridors, another gush of slick rushes down his legs while leaving a wet trail behind. It's so unbearable. thus he throws all the remaining dignity he has down to the floor and runs to Chang geng's room.


"Chang geng, chang geng....Open the door. um quickly....!!!!!!!!!!!!!!"


He bangs on the hard wooden surface of the door desperately until it opens with a small creak. Inside the room, chang geng stands right behind the door. His face instantly scrunches up when he smells the extremely sweet fragrance of honey milk. 



Chapter Text


"Yifu, what are you doing here?"


As he glances at Gu Yun, Chang Geng's brown eyes pierce through his soft and frail frame while exuding a serene demeanor.

All of the secrets Gu Yun planned to reveal and all of the lovely coaxing words he wanted to use to portray his miserable situation later in order to send his young adoptive son to the doctor are forgotten the instant he meets his eyes.

He only sees Chang Geng's handsome face and lean but strong figure in front of him. Suddenly he gives birth to an urge to throw himself into Chang Geng's warm embrace but he hasn't completely lost control over himself yet. So as long as he is in his right mind. His parental instincts will not allow him to do anything inappropriate to chang geng.


Gu Yun can fight himself even if he has to die in this manner, but he will never be able to make his mind to touch Chang Geng. He is the greatest admiral of the northwest and the head of the black iron camp's major three fractions. So, how can someone like him....


How can a person like him who defeated thousands of enemies with his own hands give in to his own desires?. 


No matter what he has to go through, he can't drag Chang geng into this mess. He only needs to ask for some help from him to grab the medicine prescription. That's it, nothing more or less. 


"Chang geng... I... I want some help from you. "


He gulps a good amount of saliva down his throat as he stares right into Chang Geng's eyes. This is more than embarrassing, so humiliating for someone as powerful and domineering as him but he knows that he has to thoroughly explain everything to this clueless boy in front of him. 


"then come inside yifu." 


Gu yun walks inside the room silently. He doesn't want to smear his slick on the boy's bed because his lower body is already soaked in the obnoxious liquid, but his knees are already weak, so he has no alternative but to sit on the floor.

A strong wave of heat whacks him on the stomach out of nowhere like a huge wave of the vast sea crashing on the shore and gu yun barely manages to stop himself from cursing out in pain. He was never a prim and proper man, to begin with, but after he took chang geng under his wing, he at least tried his best to behave well before the young boy.


"I should be a good role model to him"


He has repeated this line for thousand times in his head. That's how much he wanted to become a good yifu to his adoptive son but today, gods seem to be really testing his limits.

He can't extinguish this absurd feeling, no matter how hard he tries. He is gradually becoming aroused simply by Chang Geng's presence in the room. The mild scent of Chang Geng's pheromones has already begun to affect his body. Gu yun can't describe it because Chang Geng hasn't purposefully released any yet, but he can sense it in the thin air. He felt as if a silky fog had wrapped itself around him, making him both scared and needy at the same time.

Thus he painfully bites into his lips and proceeds to clutch onto the headboard of chang geng's bed.


On the other hand, Chang geng sees the way gu yun is suffering but he doesn't have a clear idea about the wonders happening inside that lithe body of his yifu. All he notices is that his yifu looks extremely weak on the knees and very vulnerable at the moment like never before.


" Yifu, are in pain. What's wrong with you. Can I check your body temperature?"


He steps forward to reach for gu yun but this man who is practically dying on the floor lifts his hand as a gesture for him to stop approaching him.


"I ....Chang geng. I don't want to hide it from you....anymore"


He grits his teeth and forces the words that burden him the most out of his mouth with all the courage he got.


"Omega, I am an omega"






A deathly silence



This silence bothers gu yun more than the heat itself which made his stomach a rumbling mess. He waits for chang geng to say something, anything he wants but the boy just keeps on standing with his eyes fixed on the floor as if he had secretly sinned for a long time.


"What is he thinking about?. Does he think that I am a freak? or that I don't worth anything anymore?. is he starting to despise me?. Does he want to leave the mansion ?."


When Chang Geng eventually breaks the stillness, his head is filled with all of these negative thoughts.


"I knew it"


" What!!!!"


"I knew that you are an omega "


Gu yun can't believe his ears.

What did he just hear????. Chang geng knew that he is an omega already????


"How.? I never told you that before.....I have been taking suppressants my entire life. There's no way"


"I didn't lie to you yifu"

Chang Geng raises his voice slightly to show that he is serious about what he is saying.

"At that time when I presented as an alpha, I could smell your pheromones from miles away. honey milk isn't it?. I realized that you were an omega and......and I am extremely sorry to say this but because I didn't know how to control my own pheromones I thought I'd hurt you and kept my distance from you."

He explains while deliberately dropping out the parts where he touched his painful erection every night while thinking of his yifu's beautiful face and had the aching need to hug his yifu's slender waist from behind every time he went to the sword practice sessions with him.

Chang geng moves his gaze from the floor to gu yun with a stern expression displaying on his face. He also kept this secret from gu yun without giving him the slightest hint. He always treated gu yun in the way a son would treat his alpha father and never treated him as an omega but deep down in his heart, he knew that gu yun is an omega and that he ought to take care of His family's omega with all he got.


This is the reason why whether it was wrapping his outer robe around gu yun when he was running around in the cold mornings or cooking for him and making sure that he ate a proper meal every day, he took care of all of that by himself. He wanted to protect this omega who never remembered to give himself the first place and put others in the second place.


He wanted to cherish him like a rare treasure,


because he truly loved him.......


"Chang geng I can't bear it anymore!!!!!!!!!!!!!!!!" 


Gu yun's pained cry wakes him up from his daze.


" I feel so hot. Too hot. I am going insane!!!!!"


Chang geng doesn't know what to do. This is his first time assisting an omega who is in his heat and not to mention that this omega is none other than his own adoptive father, no need to explain how confused and panicked he is. 


On the other hand, it's true that gu yun had fought with many enemies before. Be it barbarians or westerners, he had slain their heads off their bodies like chopping onions. He also had grave injuries before but nothing had ever made him feel this weak to the bone. This is the first time he is feeling so useless and pathetic. 

Chang geng puts half of the energy he has to collect his thoughts but all he sees is the heartbreaking scenario of the secret sweetheart in his dreams struggling to the extreme and fighting to maintain his composure when he is already at the edge of the hill. Gu yun grips onto the headboard until his knuckles go white with one hand while his other hand pulls at the hem of his robes until a part of it tears down, revealing a huge patch of milky white skin tainted with big and small scars all over.

This is the breaking point for chang geng. Those scars are proof of what this man had to go through in the past. He has done so much, too much for the outside world but at the end of the day, who is with him to save him from this brutal torment?.


Thus he makes the biggest mistake of his life.


without realizing that he'll have to pay for it in the future, he makes the wrong move.


He releases his pheromones.


He has no idea how can this affect an unmated omega as he hasn't thought of it ever before. All he wants to do is rescue gu yun from this nightmare but what he does results in Gu yun suffering even more. 

At first, Gu yun also thought that this was the best way to solve this problem but as he noticed that the searing pain that cannot be described from mere words had increased to another level after he arrived at Chang Geng's room, he simply put that thought in the back of his mind but now that chang geng has done it himself, there's no returning back.


Chang geng's pheromones have a unique scent. Just like the rusty smell of burned pine wood and rich wine combined together. His scent is strong and wild, showing that he is a gifted alpha, born to be a leader and it makes things even more difficult for omega in a weak state like gu yun. 

"Chang geng.... You..... Your scent....." 

Gu Yun truly wants to curse out at Chang geng for releasing pheromones without his permission but he can't resist this alluring scent no matter what. It attracts him and enchants him in every way possible. Forcing him to believe that Chang geng can satisfy all of his needs despite his young age. His mind is hazy and he can only see Chang geng through what seems like a layer of mist. In a situation like this, it is more than easy for the omega instincts he was suppressing for a long time to flare up. He loses all the self-control he once had in that particular moment.

So what comes out of his mouth is not a round of heavy scolding for chang geng but an earth-shatteringly embarrassing whimper. 

"Ah.. Chang geng, alpha your scent is too.. too me please"

His hand slowly runs upwards caressing the long loose strands of his dark hair. He pushes the strands away and shows the beautifully pale skin on his neck to Chang geng. Staring right into Chang Geng's eyes with a pair of red-rimmed peach blossom eyes, as if he'll cry in the next moment.


Chang geng instantly gets this hint. Gu yun is asking him to mark him on the neck just like every other omega in his heat. He understands that his little adoptive father is not in his right mind now and that he is just desperately trying to find a way to reduce the pain. 


After all, Chang geng is not a fool to think that his adoptive father might also have feelings for someone like him, 8 years younger, and has no experience whatsoever in love affairs and bed matters.

If only he was the Chang geng in the past, that naive boy from Yanhui Town, he would have marked him the moment Gu Yun asked for it but now he is not that person anymore. He is not just an ominous star anymore, instead, he is Li Min, the adoptive son of great marshal Gu. There's no way he can do something like that now???.

He can't take advantage of his yifu. 

He is not only his yifu but also the person he loves and adores the most in this world, he loves him more than he loves himself.


"Yifu, I'll go and buy medicine from somewhere. I promise that I will return soon. You.... Please take care of yourself until I come home. Please don't go anywhere. "


 He turns around and takes a step forward to leave only to be pulled back by a shaking hand. 


" Alpha don't go.. Please help me "
