Chao Chengyan naturally understood how important volunteer subjects were to a laboratory. It was similar to how many drugs needed to undergo clinical trials before being released on the market. Even if the effects observed in mice were close to those observed in humans, having real human subjects for experimentation would greatly increase the accuracy of the results.

Moreover, the current humans have already undergone a new round of evolution, whether it is the composition of their bodies or some highly distinctive biological elements, they have all undergone changes. To obtain more precise experimental data, it is still necessary to conduct experiments on real human beings. Without experimental subjects, many things that require human experimentation end up being tested on themselves.

Of course, Chaoning and Gaoyan were the ones who excelled the most. After all, their physical condition was quite different from others.

Currently, Chao Chengyan doesn't have a better way, so he can only choose to agree. Moreover, if it is Chao Ning he is agreeing to, he won't feel uneasy because, after all, if he didn't trust him, he wouldn't have chosen to come and find Chao Ning in the first place. Suddenly, he feels that he hasn't misjudged his younger brother and also feels a bit guilty. After all, since his younger brother came into the family, the people of the Chao family haven't released any kindness towards him. It's quite rare for him to not go astray in such an environment.

"I can be the experimental subject, but you must strictly keep all of my data confidential," Cheng Yan said after analyzing the possible consequences. "My identity is unique, and you should be aware of that. So if the secrets about me were leaked, the Zhao family will face consequences that neither you nor I can bear. A Ning, even so, are you still willing to have me as your experimental subject?"

After calming down a bit, Zhao Ning also thought about this problem. He pinched his ear and felt uncomfortable with Zhao Chengyan's address to him. "Here's the thing, big brother. After I go back, I will discuss it with my other colleagues. Of course, I have to make it clear first that if you want to become the subject of our laboratory's experiment, then all of our colleagues will know about it. I can vouch for their character, but I also hope that you truly believe in us."

"...With your assurance, I'll feel at ease." Zhou Chengyan knew that this matter was almost certain, so he took a sip of tea. "How have things been at home recently?"

When Zhao Ning heard this, he instinctively touched his neck and said, "...I guess it's fine, just like that."

"I encountered a very dangerous Alpha at the entrance of Star Gate," Chen Yan said with a serious expression. "What is your relationship with him?"

"What... what kind of relationship?" Zhao Ning had the feeling of being caught off guard, "Alpha? I don't know anything about it."

Chao Chengyan looked quietly at Chao Ning.

After all, he was someone who had seen the battlefield; just one look from him was enough to send shivers down one's spine.

Zhao Ning was timid, and after being glanced at by Zhao Chengyan, he felt a cold sweat running down his back. He tightly clenched his pants leg, barely refraining from revealing the fact that Shen Xi had marked him. Although he had been sent to the Gu family as an Omega and there was a certain probability that Gu Xiangnan would mark him in the future, it was likely that the Zhao family had already prepared for this. But speaking of such matters was still very embarrassing, especially since he was an Alpha.

Being marked by an Alpha is not something honourable, let alone...

Still, in an unwilling situation.

"It's better not to cause trouble for his brother at a time like this."

Zhao Ning cleared his throat and said, "It's no big deal. There are so many Alphas coming in and out of school every day, I don't know which Alpha you're referring to. I am very low-key at school and won't cause any trouble for the Zhao family."

"......That's not what I mean." The guilt towards his younger brother resurfaced in Zhao Chengyan's heart, and he inwardly sighed, deciding not to pursue it any further. "After all, you are also an Alpha yourself. Regardless of rank, you have a responsibility to take care of yourself. As your older brother, I don't want you to get hurt."

Zhao Ning's response was perfunctory: "Yes, yes, I understand, Big Brother."

"Hmm." Chao Chengyan took another sip of tea. The tea at this shop was indeed excellent and suited his taste. Perhaps he should frequent this place.

Zhao Ning had no idea about Zhao Chengyan's plans. She absent-mindedly finished the cake in front of her and then made an excuse to bid farewell to Zhao Chengyan before heading back to school. Once back at school, Zhao Ning transformed back into the low-key Zhao Ning who enjoyed conducting experiments in the lab. He went straight to the lab and told Gao Yan and the others about what had happened, instructing each of them to keep it a secret.

Gao Yan's complexion did not look good. "... Are you sure your Big Brother reacts to my pheromones?"

Chao Ning scratched his head and said, "My elder brother shouldn't be mistaken, right? After all, he is an S-level Alpha."

"..." Gao Yan took a sip of water with a cold expression on her face. Not only was she not happy, but she also felt a bit repulsed. Perhaps it could be said that because of Chao Ning, she rejected everyone from the Chao family, even though it seemed like this older brother hadn't done anything to Chao Ning.

Chris glanced at Gaoyan and chuckled twice before saying, "I have no objection if your older brother is willing to be a volunteer in our laboratory. Henry, do you have any objections? You see, if our eldest brother agrees to be subject, we can perform surgeries on him without any guilt, and it's quite exciting to think about."

Upon hearing these words, Gao Yan responded with a mocking tone, "Well, Chris, you're using our Chinese idioms pretty well at this moment."

Chris raised an eyebrow, "Of course."

Henry, of course, had no objections. The last time he saw Gu Xiangnan, he had been scared once before. Although it wasn't Gu Xiangnan who was going to be the experimental subject this time, Chaoyan was not bad either, since he was from the Cha family. After thinking for a moment, he also felt very excited.

"I don't have any problem either!" Henry happily agreed.

Zhao Ning nodded and opened her computer, preparing to write an application email. After all, this was a big deal. The laboratory wanted to recruit a volunteer for an experimental subject, and they needed approval from the head of the research group, which was their advisor. Considering Zhao Chengyan's unique identity, this matter couldn't be taken lightly.

After the email was sent through the dedicated channel, Chao Ning breathed a sigh of relief and was about to discuss with them where to go for dinner in the evening when he received a message from Gu Xiangnan. The content of Gu Xiangnan's message was very simple, with only two words - "Come back."

He knew why Gu Xiangnan asked him to return home at this time. Either Shen Xi disappeared, or other members of the Gu family had already found out that Shen Xi had turned into an Alpha. In the end, they all lived under the same roof, and there are no walls in the world that are impervious to wind, especially in the Gu family.

"But what does it have to do with him?"

[Ning: Sorry, I have final exams these next couple of days and I won't be able to come back.]

"[Ning: Besides, Shen Xi turning into an Alpha doesn't concern me at all, so it shouldn't affect me whether I go or not, right?]"

Guxiang Nan, on the other end of the Light Brain, had a gloomy expression. It was true that the matter of Shen Xi's secondary differentiation had nothing to do with Chaoning, but how would he cancel the engagement if Chaoning didn't come back?
