"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 of that?" he asked in amusement, "If you throw a musician into a deserted place, then 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 in 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 is 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 now, and it will be a while before I can go back to school," she said.
