"It's true." Yuan Yisheng said, "In fact, it's easy to use chemistry to kill someone, such as explosion, poisoning, or..."

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

For a moment, Yi Qianjin felt his heart beating wildly, and an inexplicable sense of crisis arose, as if the instinct of the body was urging her to escape the boy in front of her.

But, how could you feel like this?

"So, you must pay close attention to safety issues in these chemicals, otherwise it will be bad if you are interested in using them." Yi Qianjin quickly interrupted the tunnel.

"Yes, it's time to pay attention to safety issues." Yuan Yisheng said.

"What about you, do you choose the chemistry major because you like chemistry?" she asked after a different question.

"It's just that some interest, different chemicals, combined together, will form different reactions, which can save people or kill people. Don't you think it's quite interesting?" he said.

"Uh..." This was the first time she heard people describe chemistry like this, "I just felt dangerous."

"What do you like? Piano?" she asked.

"Yes, I do like piano," he admitted. "I even thought that piano was something I had to work hard for my whole life."

"Then why don't you choose the music department?" she said strangely.

"Because it's useless." He smiled.

"Isn't it useful?" She frowned, not agreeing with his words, "How could it be useless? Music can cultivate sentiment and make people feel happy. Even like me, I am learning music therapy, and I can use music to treat patients in the future."

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

She suffocated, "No matter what, music can be used as spiritual food and can relieve stress. Even in war, music can boost morale!"

"Often people who say such words are materially rich. If you are famine, no one will think of music. As for war and the inspirational effect of music, the premise is that during war, you still have enough soldiers, otherwise, there will be no effect."

Yi Qianjin bit her lower lip with her teeth. The person in front of her was playing the piano so well, but she was talking to her about music.

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

"That was to remind myself not to forget certain things." He said. Through practicing piano over and over again, he could constantly tell himself that he should be ruthless and not be ruthless. The meaning of his return is to end the unfinished hatred back then.

"Don't forget what?" she asked.

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

Only then did she realize that what she said just now was like inquiring about his private affairs.

"Well, I...I just asked casually. Sorry, I shouldn't have inquired about your private affairs." She said quickly.

"I'm not interested in telling my private affairs to irrelevant people," he said, turning to continue his experiment.

She watched quietly from the side, and when the two left the laboratory, she 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 a silent call.

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

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