Chapter 581: 337

Fan Lei came over, looking puzzled, and said, "Teacher He? Look at me!" As he spoke, he lightly slapped the table and yelled, "Earthquake!"

After finishing, he and Li Renzhe laughed together.

Zhao Yi opened his eyes in a daze and muttered an unfriendly remark, something along the lines of cursing one's ancestors. Only then did he notice He Hongbo and quickly stood up to ask, "Teacher He?"

He Hongbo nodded and smiled, saying, "Ah, Zhao Yi, when doing research, there are successes and failures. Like when I was doing experiments initially, a test tube exploded once and burnt my hand, look."

He showed the scar on the back of his hand, and added, "Burnt by sulfuric acid."

"Oh."

Zhao Yi nodded and said to himself, "It seems that such potentially dangerous chemistry experiments are best left to others..."

He Hongbo opened his mouth, not knowing what to say. He originally wanted to comfort Zhao Yi, but finding that Zhao Yi seemed really fine, there was no need to say much else.
