Li Zheng, already well-grounded, stepped into the laboratory with the stability of Mount Tai after a specialized study session of over ten minutes (hours).

But in Teacher Hu's eyes, he seemed to be a completely different person.

This was not only a contempt for chemistry but also a scorn for scientific research itself.

Seeing that the teacher was about to lose his temper, Shen Yiyun hurriedly put down what she was doing and intervened, "Stop making a fuss, Li Zheng... maybe you should leave first..."

"It's not like that..." Li Zheng explained, "After all, I have studied under Teacher Hu before, and I just happened to look over the papers published by Teacher Hu's research group in recent years. I'm somewhat familiar with photovoltaic research. Most of the content you showed me earlier is what I already understand; I just need to confirm the progress of the experiments."
