two trees for forest

Chapter 40

"Hey hey, Dongyu Dongyu, help me look at this physics problem, mother, I have calculated it three times, and I have calculated three answers, and there are still options in it!!"

Lin Dongyu heard Shen Jin yelling there again, without raising his head, he said calmly: "See if there are more choices."

"..." Lao Tzu is not as smart as you but not mentally retarded!

Shen Jin directly "slapped" his workbook on the cloze that Dongyu was doing, "Show me first. Hey, I'll go!!!"

What made Shen Jin almost scold was that the light above his head suddenly flickered and then went out.
