Shen Xi did not stay near the school as before. While Chao Ning felt relieved, he also felt a little bit lost. He didn't know where this eerie sense of loss came from, but it felt very wrong. He rubbed his ears and didn't think much about it. He walked quickly towards a relatively secluded small shop near the school.

Although this shop is small and somewhat secluded, the food here tastes really good. The owner of this small establishment is a middle-aged beta male, who is gentle and easygoing. He never cares about how many customers come here every day, he only hopes that everyone can have a happy meal here.

Chao Ning likes this boss. When there's nothing to do, she would secretly come to this boss's store sometimes alone, sometimes with Gao Yan and the others. This store doesn't have a name, but its exterior wall covered in ivy is its most distinct feature.

Chao Ning likes to call it the Green Pavilion.

"'Uncle Hu.'" Chaoning greeted Boss Hu as soon as he entered the door.

"Xiaoning is here? Are you the only one here today? Same as always?" Uncle Hu looked over, lowered his glasses, and held a yellowing newspaper in his hand.

"In this era, newspapers are also rarely seen. It is said that most of them are personally printed by Uncle Hu using manual methods. The content comes from all corners of the country and there is no specific theme. However, Uncle Hu often peruses through them."

"Yes, there, later I have a friend coming over, so... prepare an extra cup of tea, any type of tea will do." Initially, Zhouning had not planned on preparing anything for Zhouchengyan, after all, he didn't know what Zhouchengyan liked. However, he often saw Zhouchengyan drinking tea, so he assumed it must be something he enjoyed.

After taking his seat in his usual spot, he sent a location request to Chao Chengyan. It didn't take long before Chao Chengyan arrived. Upon entering, he was momentarily surprised by the furnishings of this small restaurant but did not show excessive interest.

Uncle Hu soon brought over the sandwich with the filling that Chaoning wanted, along with coffee that had double the amount of sugar and green tea.

Chao Ning fidgeted a little and said, "I don't know what kind of tea you like, so I ordered a cup for you. If you don't like it..."

"Sure." Chao Chengyan interrupted Chao Ning, picking up the warm tea and taking a sip. The slight furrow between his eyebrows instantly smoothed out, saying, "...This tea is not bad."

Chao Ning looked at Uncle Hu with some surprise. He didn't like drinking tea, and he had never seen anyone order tea at Uncle Hu's shop, so he had no idea about Uncle Hu's tea-making skills. But he never expected that it would impress Chao Chengyan enough to praise it. In an instant, he became less reserved and smiled before getting straight to the point. "Big brother, you said you needed to ask me something. What is it?"

Chao Chengyan glanced over at Uncle Hu, who was not far away.

Uncle Hu quietly stepped away from the bar and retreated to the back room.

In the lobby of the Green Pavilion, only Chao Ning and Chao Chengyan remained.

In front of him was his younger brother. Although they couldn't be considered well-acquainted, Chen Yan didn't bother with any pleasantries and went straight to the point, "If an S-class Alpha were injected with a worm tribe Alpha pheromone infused with worm tribe serum, is there any way to resolve the situation?"

Zhao Ning was a bit puzzled, "Resolve what? Did someone get injected with the Alpha pheromone of the Bug race and have a severe rejection reaction?"

It's like a blood transfusion or bone marrow transplant. Pheromones can be supplemented or even converted and replaced through other means, but there can still be a rejection reaction. Pheromones contain a special enzyme that can identify the gender and level of foreign pheromones or hormone-like substances. However, this is only a preliminary judgment. If the gender and level match, it still depends on whether this enzyme will become inactive after encountering foreign pheromones. If it becomes inactive, rejection will occur. Whether it's an Alpha or Omega, the likelihood of experiencing rejection is high. Once rejection occurs, the probability of going into shock is also significant, and it has a positive correlation with the level of pheromones.

"...It was me." Chao Chengyan's expression was somewhat unnatural. "During that previous battle, I had inadvertently been injected with an unknown substance into my glands. However, I didn't have time to pay attention to it at the moment, nor did any other reactions occur at that time. It wasn't until after the war ended that I started experiencing episodes of fever, although not severe. Does this count as an adverse reaction?"

"……Fine." Zhao Ning felt her brain was somewhat lacking. "But how did you know that thing was an information pheromone of the Insect Clan's Alpha? Regular hospitals don't have these types of detection devices, only Star University's laboratory... Did you perform the test in Star University's laboratory? Who conducted it for you?"

Chao Chengyan shook his head and said, "I did it myself. No one knows. I deleted the records of the equipment and cloud storage afterwards, so no one knows."

"What are you telling me this for, Big Brother?" Zhao Ning looked at Zhao Chengyan up and down. "If this substance doesn't cause a severe adverse reaction with you, there shouldn't be many problems in the later stages. Of course, there might be some residual effects, because nothing is completely risk-free, especially in your case... But currently, there is no information available to check, as a situation like yours has not been encountered by me or, I should say, the laboratory. So, Big Brother, what kind of problem have you encountered?"

When it comes to academics, Chaoning always has a lot to say. Unlike the person at home who constantly tries to diminish their presence and never refuses or rebels, Chaoning is always talkative and enthusiastic.

Cheng Yan was somewhat surprised by Cheng Ning's reaction, but he also had a bit more trust in his younger brother. He no longer felt embarrassed and directly said, "I can no longer sense any pheromone fluctuations from Omega."

"Ah?" Zhoun Ning was so shocked that her jaw almost dropped.

So, his eldest brother's aftereffect is "cystectomy"? After all, what's the difference between an Alpha who can't sense Omega pheromone fluctuations and being castrated? Even this inferior Alpha can sense it, albeit with a very low probability of reaction.

"Are you sure? Is it that you can't sense it, or is it that you can sense it but it doesn't trigger a reaction?" Zhang Ning asked with a serious expression, "The nature of these two scenarios is quite different."

Chao Chengyan's expression grew solemn, "I can't sense it. However..."

Zhao Ning tilted her head slightly and asked, "But what?"

Chao Chengyan's expression became more serious. He said, "It seems like I can sense the pheromone fluctuations of that female Omega today, and..."

"Any reaction?" Zhounning swallowed his saliva, "You have a response to Gao Yan's pheromone fluctuations? That's amazing!"

Zhao Chengyan raised an eyebrow, "?"

Chao Ning's occupational disease suddenly flared up, and he completely forgot that he was not very familiar with this older brother. "Brother, would you be willing to be a volunteer in our laboratory? If you are willing, perhaps we can help you solve your problems. And if the research yields results, you would have made a great contribution to the progress of all humanity!"

Chao Chengyan: "????"
