After get off work, Lu Huangzhi asked Zhao Yesi to go to the Boonie Bears lab with him again, but Zhao Yesi refused: "Go again? Do you want to give Boonie Bears a double kill?"

"Although I don't know what Bear Outing told you, don't you want to know why the temporary marking couldn't control your last susceptible period?"

Zhao Yesi was stunned for a moment, then pounded the table angrily: "Damn it, I want to know."

Lu Huangzhi picked up the backpack that Zhao Yesi had hung beside him and put it on his shoulder: "Let's go."

"Why are you taking my bag? I have to come back and work overtime."

"Go home early to play games on your first day at work, and add more tomorrow."

"No, unless you assist me."

"Okay, I'll delete one entry after each round to keep my grudge."

"Be a human being, Lu Xiyou. You were the one who invited me to fight first."

Arriving at the lab, Zhao Yexi said, "Can we ask the male researcher? He seems like a normal person to me."

Lu Huangzhi said indifferently: "Okay."

Xiong Chumo was not there at the time, and the male researcher said that she had gone to Director Zhao's office to ask for funding again.

Zhao Yesi: You used the word "again" very precisely. This simple word depicts a bloody scene.

Lu Huangzhi asked, "Is the institute short of money recently?"

The male researcher smiled wryly and said, "It's probably short of a hundred million. What are you doing here?"

Lu Huangzhi told the male researcher that the temporary marker had failed. The male researcher said, "Wait a moment."

The male researcher pulled up the experimental files on his tablet, scrolled to the end, and clicked on the "Zhao Yexi & Lu Huangzhi" section. The files detailed every experiment Zhao Yexi and Lu Huangzhi had conducted, from the experimental principles and design to the experimental process and conclusions. The files were vividly illustrated with pictures and text. The attached pages contained the two individuals' identification information and medical examination data.

The male researcher flipped to a page and said, "During Zhao's last susceptible period, Lu was collaborating with Xiong Chumo on an experiment for the alpha susceptible period. Your pheromones reached a peak at the same time, and the temporary markers were no longer sufficient for you. It's normal for you to lose control."

Zhao Yexi asked, "So, as long as our susceptible periods don't overlap, that situation won't happen?"

"Not really," the male researcher said, "Temporary marking can't completely solve the problem of omegas going into heat..."

"Ohhhh, 500 fine!"

The male researcher said calmly, "I said 'estrus', not 'estrus period'."

Zhao Yesi was stunned. "Is this even possible?"

Lu Huangzhi said: "Please continue."

"During Zhao's first few susceptible periods, despite being temporarily marked, he maintained a low-grade fever and sensitivity, forcing him to take leave and rest at home. We compared this with other experimental groups, and the results were similar. After three to five temporary markings, the omega's demand for alpha pheromones peaks, and simply biting through the glands to inject pheromones is no longer enough. To calm the omega, we had to give them intravenous fluids. I guess you all ended up going to the hospital as well."

Zhao Yexi: "..."

Lu Huangzhi: “No.”

"So you guys...?"

A short pain is worse than a long one. Zhao Yesi said in despair, "It's just what you think. If you ask again, you will commit suicide."

The male researcher wasn't just in awe; he was practically in worship. "Can you tell me about your experiment?" Seeing Zhao Yesi's "I'm really going to commit suicide" expression, the male researcher quickly added, "I'm asking you to talk about your experience from the perspective of pheromones."

During the three days of the susceptible period, Zhao Yesi was dizzy all the time. It was not to the point of blackout. He had to think hard to recall many details, but he still remembered the feeling at that time very clearly.

There is a great sense of fulfillment and satisfaction both physically and mentally, just like an alcoholic who has finally overcome his addiction after six months of hard work to quit drinking and can't stop at all.

Towards the end of the experiment, he felt like he was going to break down, and he scratched at Lu Huangzhi's back. Lu Huangzhi thought he was really unwell and asked him if he wanted to rest, but he pestered him and refused to let him go.

"Student Zhao?"

You never know what's going on in the mind of the baby-faced guy standing in front of you.

Zhao Yesi said calmly: "Let's write a report and send it to you."

Lu Huangzhi asked: "What do you mean from the perspective of pheromones?"

"It's more of a psychological perspective."

"Like this." Then there's no need to write about how delicious and juicy the peaches are.

Before leaving, Zhao Yesi hesitated for a long time and couldn't help asking: "Teacher, was the first case of pregnant man diagnosed in your laboratory?"

"Yes," the male researcher said, "The institute has assigned him a strong medical team to ensure the safety of him and the fetus."

“What is male pregnancy like?”

"The man is only a month pregnant. We'll need to explore this issue slowly before we can find out." The male researcher said, "So far, it seems that the process of male pregnancy is very similar to that of female pregnancy. We can probably compare the omega's susceptible period to the dangerous period. Omegas in the susceptible period are more likely to get pregnant."

Zhao Yesi glanced at Lu Huangzhi. Hearing them talking about male omega pregnancy, Lu Huangzhi had no particular reaction. He really didn't know if he was really stupid or just a jerk.

After returning home, Zhao Yexi made a point of researching pregnancy. It's said that a blood test can confirm pregnancy as early as seven to ten days after sex. Early pregnancy symptoms include nausea and vomiting, loss of appetite, lethargy, and acidosis.

Calculating it, today was exactly seven days since he and Lu Huangzhi finished their experiment. He decided to get a checkup tomorrow and face his bleak life head-on.

If she is really pregnant, I don’t know anything else, but he will definitely catch Lu Huangzhi to make soup and add a lot of ginger.

Lu Huangzhi took his gaming laptop and brought it to the door. "What do you want for supper? I'll order it now."

Zhao Yesi looked at the ingredients for the soup, his eyes filled with resentment.

Isn't Lu Huangzhi usually quite smart? Why is he so slow when it comes to big things and not understanding at all?

Lu Huangzhi:?

"Aren't you afraid of turning into a piglet if you eat midnight snacks every day?"

"Don't worry, I won't get fat no matter how much I eat."

Zhao Yexi was a little envious. Then he thought, what's there to envy? He also has a physique that can't gain weight no matter how much he eats. Not only does he not gain weight, he doesn't even grow taller.

"Let's order some fruit," Lu Huangzhi said, "Cherries? Do you want something sour or sweet?"

"Of course it's sweet. Are the sour ones for people to eat?"

Lu Huangzhi looked at Zhao Yesi, trying to decipher the reason for his agitation from his expression. Unable to decipher, he could only defer to the junior high school leader: "Well, we only eat sweets."

After finishing a game, Lu Huangzhi went to wash the cherries that had just been delivered. When he came back, he saw Zhao Yesi sitting on the gaming chair, stretched out in a motionless position, as if he was frozen by some skill.

"What's wrong?"

Zhao Yesi murmured, "I just yawned."

"I don't see—isn't it a cute fight?"

"It's not a question of whether it's cute or not." Zhao Yesi asked suspiciously, "Have you noticed that I've been rather sleepy lately?"

Lu Huangzhi said carefully: "It's okay, I think I'm more sleepy than you."

This is the truth. Lu Huangzhi loves to sleep much more than him, but no matter how sleepy Lu Huangzhi is, there is no need to worry about pregnancy.

Lu Huangzhi knew that Zhao Yesi had something on his mind, and he wanted to wait for Zhao Yesi to speak out, but he couldn't help it.

"What on earth is Zhao Zhitao thinking about?" Lu Huangzhi passed a cherry to Zhao Yesi's mouth. "Tell me, okay?"

Zhao Yesi's composure failed him. He bit his cherry, and there was a little complaint in his voice that he himself didn't even notice: "Why aren't you worried at all?"

Lu Huangzhi was a little surprised, "What should I worry about?"

"We've done this so many times, aren't you worried that I'll become the second male omega to get pregnant?"

Lu Huangzhi was silent for a moment and said, "I don't think I need to worry."

Zhao Yexi laughed angrily: "That's right, anyway, it won't be you who is pregnant."

Lu Huangzhi didn't know what expression to put on: "So, you really don't remember that I wore a condom?"

Zhao Yesi was surprised and asked, "You are wearing it?"

"Um."

So he was worried and suspicious for nothing?

Zhao Yesi couldn't help but ask, "Why are you wearing it?"

Lu Huangzhi asked back, "Why don't I wear it?" After going through so many levels and countless tests, no matter how bizarre Zhao Yexi's thinking process was, he would no longer be surprised. "I've taken a physiology class."

"No... I mean, where did you get the condom?" Zhao Yesi thought of something, "Do you carry it with you?"

“…In the guesthouse.”

Zhao Yesi still had some common sense. The weight of his heart finally settled. "Why didn't you tell me earlier?"

Lu Huangzhi was speechless: "Do I need to tell you this? Don't you know whether I'm wearing it or not?"

Zhao Yesi knew he was in the wrong and whispered, "I was dizzy, how could I remember so many details?"

"Then let me remind you." Lu Huangzhi said, "The next night, you had an attack in the middle of the night. Did I stop you?"

He had just fallen asleep when he woke up to a sweet, soft omega on top of him, nearly losing his balance. Luckily, Zhao Yexiren was dizzy, and after trying for a long time to get the position right, he finally woke up, picked him up, and coaxed him, "Don't worry, baby, wait for me to put something on."

Zhao Yesi remembered everything. He remembered that he was still unhappy after Lu Huangzhi took him down, crying and saying a lot of nonsense.

Good man, what kind of human being is he? Just go to heaven right here.

Lu Huangzhi smiled and said, "Do you remember now?"

Zhao Yesi's face flushed so red that blood almost dripped out: "...Yeah."

Lu Huangzhi fed Zhao Yesi another cherry and said, "Are you still worried?"

Zhao Yesi shook his head, then nodded and said, "Even so, there is still a chance."

Lu Huangzhi thought for a moment and said, "Then I'll go back to the institute and work overtime."

Zhao Yexi: “?”

"I'll finish the New Marriage Law as soon as possible so that I can be responsible to you, Xiao Zhitao."

In order to eliminate the last chance, Lu Huangzhi took Zhao Yexi to the laboratory for examination a few days later.

Looking at the words "not pregnant", Lu Huangzhi said: "This is a completely unexpected result."

Zhao Yesi covered his face with his hands: "Stop talking."

"Next time, remember to check if I'm wearing it before you sit on it."

Zhao Yexi chuckled: "Next time? There will be a next time?"

"Why not?" Lu Huangzhi said, "After three to five temporary markings, it will no longer work on susceptible omegas—that's what the male researcher said."

"Yeah," Zhao Yexi was puzzled. "But can't I still use an IV to solve it? Besides, the inhibitor should enter the clinical trial stage in the next two months. I will definitely participate in the trial then."

Lu Huang was startled and whispered, "Fuck."

Dating really does lower your intelligence. It seems that if you want to sleep with Zhao Zhitao with a clear conscience, you must first pursue her and confirm her status as your boyfriend.

It's a bit cruel to have to abstain from sex once you start eating. He probably won't be able to wait until the grudge book is finished.

While they were waiting for the elevator, they happened to meet Zhao Guangyao who was taking the elevator up. Zhao Guangyao was very happy to see his son after a long absence and asked: "Are you back from your business trip?"

Zhao Yexi said, "We have been back for several days."

Lu Huangzhi greeted politely: "Hello, uncle."

Zhao Yesi:?

He remembered that the last time Lu Huang saw his father, he called him "Director". What did it mean that he suddenly changed his words?

Zhao Guangyao saw the medical report in Zhao Yesi's hand and asked, "What are you holding?"

Zhao Yesi suddenly felt ashamed as if he had been caught in a premature love affair. "Yes...it's a secret of our department."

Zhao Guangyao smiled and said, "What secrets of your department are there that I cannot know?"

Zhao Yesi pretended not to hear and asked, "Dad, why did you come to the lab? Are you here to give me money?"

Zhao Guangyao said happily: "The money problem has been solved."

Second-gender research is a top priority for public health, requiring significant financial and labor resources, and even generous government funding can sometimes fall short. A few days ago, the ABO Institute received a substantial private donation, alleviating their immediate needs and providing comfort to Ms. Xiong, who had become furious over lack of funds.

"I came to see Teacher Xiong today to discuss something with her. Since you guys are here, come and listen."

The ABO Research Institute's exploration of temporary marking has reached a mature stage. It has been confirmed that temporary marking of omegas by alphas with high pheromone matching has many benefits, including stabilizing hormone levels in the omega and alleviating psychological disorders such as ADHD and mania.

Zhao Guangyao felt that it was time to make the concept of "temporary marking" public, but he was hesitant to make up his mind because of the side effects of temporary marking.

"After temporary marking, the alpha will develop a possessive and protective desire towards the omega; the omega will also become dependent on the alpha who marked him. A large proportion of those who differentiate into a second gender are minors, and they lack strong self-control. I am worried that some people will abuse the temporary marking, and even more worried that they will not be able to maintain their sanity in the face of its side effects."

Xiong Chumo said, "An alpha bites the omega's glands and then injects his own pheromones. This is instinctive for every alpha, just like eating and sleeping. Even if no one teaches them, they will figure it out on their own. Right, Mr. Lu?"

Lu Huangzhi: “Yeah.”

Even before Zhao Yexi's glands fully developed, he had inexplicably become concerned about the patch of skin on the back of Zhao Yexi's neck. After Zhao Yexi began to secrete pheromones, he became increasingly greedy for that spot, and at one point he even considered taking a bite.

Zhao Yexi said, "I think this is actually the same as sex education. We can't deliberately avoid it just because we're worried about corrupting minors. They need proper guidance and they also need to learn to be responsible for their own actions."

Zhao Guangyao patted his thigh and said, "Then it's decided—announce it!"

How to announce it specifically is the Propaganda Department’s responsibility, and they don’t need to worry about it.

As graduation season approached, Guan Chengji interrupted Zhao Yexi's internship and asked him to return to school to concentrate on preparing for his defense.

Besides defending his thesis, Zhao Yexi still had a lot of graduation paperwork to complete. The ABO Institute was too far from the university town, so he simply moved out of the staff apartment and back to his own home.

This means that the [Breath of the Wild] duo is finally - untied!

Now that he thought about it, his relationship with Lu Huangzhi had reached this indescribable point at the ABO Institute. Their workstations and apartments faced each other, they saw each other every day, worked on experiments together, and went on business trips together. Their pheromone compatibility was so high, it would be strange if nothing bad didn't happen.

Lu Huangzhi drove Zhao Yesi home. When the car arrived at the gate of the community, Zhao Yesi said, "Okay, I'll be here."

Lu Huangzhi parked the car and said, "I'll take you upstairs."

"No, I don't have much."

"I want to find my way around." Lu Huangzhi said, "When my susceptible period comes, I'll know where to go to drink Zhizhi Taotao."

Zhao Yexi said, "You're already in your susceptible period, and you're still running around? When the time comes, just send me a WeChat message and I'll send you food."

Lu Huangzhi smiled, "You're so willing. But I can't bear to let Zhao Zhitao run around, so I'll just deliver the goods to your door."

Zhao Yesi felt relieved when hearing this, so he took Lu Huangzhi back home.

Zhao Yexi's home is very close to the university; his parents bought it specifically for him. Zhao Yexi experienced four years of group living during his undergraduate studies, and not wanting to repeat that experience, he lived at home for three years during his graduate studies.

The house has three bedrooms and two living rooms, but only one bedroom. The remaining two rooms are a study and a game room respectively.

Lu Huangzhi asked, "Where should we sleep if there are guests?"

"I decorate my own house however I like, taking into account the type of guests I'll be meeting."

Lu Huangzhi grasped the key point: there was only one bed in Zhao Zhitao's house.

After Zhao Yexi's glands had grown back, he had basically lived in the staff apartment. The house, on the other hand, didn't smell of his pheromones. Lu Huangzhi said, "You should work harder and leave your scent in the house as soon as possible."

Zhao Yesi said coldly: "I'm not building a nest, why should I work hard?"
