"That's true." Yuan Yisheng said, "Actually, you have to use chemistry knowledge to kill someone. Sometimes it's very simple, such as explosion, poisoning, or..."

His voice paused, and his dark eyes looked at her faintly.

For a moment, Yi Qianjin felt her heart beating wildly, and an inexplicable sense of crisis suddenly arose, as if her body's instinct was urging her to run away from the boy in front of her.

But, how come you feel like this?

"That's why we need to pay close attention to the safety of these chemicals, otherwise it will be bad if they are used by malicious people." Yi Qianjin quickly interrupted.

"Yes, we should pay more attention to safety issues." Yuan Yisheng said.

"What about you? Did you choose chemistry because you like chemistry?" She changed the topic and asked.

"I'm just interested. Different chemicals, when combined together, will form different reactions. They can save people or kill people. Don't you think it's quite interesting?" he said.

"Uh..." This was the first time she heard someone describe chemistry like this, "I feel dangerous."

"Then what do you like? Piano?" she asked.

"Yes, I do like the piano." He admitted, "I even thought that the piano was something that I would work hard for throughout my life."

"Then why didn't you choose the music department?" she asked curiously.

"Because it's useless." He smiled.

"It's useless?" She frowned, not agreeing with what he said, "How could it be useless? Music can cultivate sentiments and make people feel happy. Even like me, I studied music therapy and I can use music to treat people in the future.

patient."

"But what's the use?" he asked in amusement, "If you throw a musician into a deserted place, you will find that music has no effect on your survival except self-satisfaction.

"

She choked, "No matter what, music can be spiritual food and relieve stress. Even in times of war, music can boost morale!"

"Usually people who say this are people with abundant material resources. In case of famine, no one will think of music. As for the inspiring effect of music in war, the premise is that during the war, you still have a sufficient number of soldiers.

Otherwise, it will have no effect at all.”

Yi Qianjin bit her lower lip, knowing that the person in front of her could play the piano so well, but he was talking about music to her.

"If it's useless, then why do you always go to the piano room to practice?" she said.

"That's to remind myself not to forget certain things." He said that through practicing the piano over and over again, he could constantly tell himself to be ruthless and not to be soft-hearted. The meaning of his coming back was to

Settle the unresolved hatred from back then.

"Don't forget something?" she couldn't help but ask.

"You want to know?" He stared at her.

Only then did she realize that what she just said seemed like she was inquiring into his personal affairs.

"Well, I... I just asked casually. I'm sorry, I shouldn't inquire about your personal affairs." She said quickly.

"I'm not interested in talking about my private matters to irrelevant people." After he finished speaking, he turned around and continued his experiment.

And she watched quietly from the side. When the two of them left the laboratory, they realized that it was already dark.

At this moment, Yi Qianjin's cell phone rang. Yi Qianjin took out his cell phone and saw that it was Shen Hefei's call.

When she connected, Shen Fei's voice came from inside, "Xiao Jin, where are you? I heard from the people in your dormitory that you didn't go back to the dormitory in the afternoon?"

"I'm outside right now, and it will be a while before I can go back to school," she said.

"Then I'll wait for you to have dinner together." Shen Yanfei said.

Just as Yi Qianjin was about to agree, Yuan Yisheng on the side said, "It's dinner time now, so let's find a place nearby to have dinner first."

"Huh?" Yi Qian was stunned for a moment, and Shen Jifei on the other end of the phone also heard Yuan Yisheng's voice.

"Xiaojin, who are you with?" he asked.

"I'm with Yuan Yisheng now, um... Xiaofei, why don't you wait for me to have dinner together, I'll finish eating outside and then go back to school."

On the other side of the phone, after a moment of silence, Shen Hefei said, "Okay, do you want me to pick you up later?"

"No, I'll be back after dinner." Yi Qianjin said.

After the phone call ended, she looked up and saw Yuan Yisheng looking at her with an indescribable look.

"What's wrong?" she asked.

"Nothing." He said calmly, "Is the person who called you just now your friend?"

"Well, we've known each other since we were very young. His name is Shen Jingfei." She said while observing his reaction.

What disappointed her was that after hearing the name, his face became calm.

"Have you ever heard of this name?" she asked.

"I've heard of it," he said.

She then said excitedly, "When did you hear this name?"

"Shen Jingfei is your childhood sweetheart, Yi Qianjin. He is very famous in the school. You can find out just by going to the school forum," he said.

"That's it." She sighed, and since the scandal photos of her and him were posted on the school forum, the popular posts on the forum have become posts speculating on the relationship between the three of them.

"Otherwise, how do you think I know?" he asked.

She touched her nose, wondering once again whether he was Mu Yuan or not, and whether what he said was something he deliberately concealed.

"Let's go eat." He said, taking the lead.

She quickly raised her steps and followed behind him.

The two of them found a noodle shop. The noodle shop is a small shop with a small front and an old decoration, but there are quite a lot of people inside and the business is good.

Yuan Yisheng found a seat and sat down, and Yi Qianjin also sat down, but when she was choosing what noodles to order, she was in a daze while looking at the menu.

"What, don't you want to eat noodles here? Do you think the environment here is too bad? The food is too simple?" Yuan Yisheng said mockingly.

She looked up at him and asked, "Do you hate me?"

"How do you say that?" he asked.

"Because you always seem to like to taunt me." She said, "I don't want to eat noodles here, and I don't think the environment is so bad or the things are so simple. I didn't live in such a bad way since I was born. Very good. Before I was born until I was five years old, my mother took me with her, eating simple box lunches, squatting on the side of the road and eating bread..."
