While Li Zheng was succumbing to his "Entering Demonization" alone, Lin Yujing and Gu Jianfeng had already put down their weapons.
Gu Jianfeng put away his pen and, holding the Mechanics Book, tilted his head and smiled, "Although I didn't understand your approach, being able to realize what I don't understand is already a blessing in itself."
"Um." Lin Yujing nodded vigorously, "My math teacher said my ceiling isn't high… I've always been unwilling to accept it, but after hearing your approach, I realized it's true, I need to step it up."
"Not at all, not at all… your understanding of physics is truly strong…" Gu Jianfeng scratched his head and chuckled foolishly, "Well, see you at the experimental exam, then."
"Okay."
After parting with Lin Yujing, Gu Jianfeng ran up behind the dazed Li Zheng and patted him on the back.
"Let's go."
"Ah? Huh?" Li Zheng just snapped out of his trance and turned around, "Stay a bit longer, I still want to ask you about the math competitions."
