Zhai Zhu's gaze froze. It was Song He!
She suddenly remembered something, and her heartbeat began to quicken. Her eyes flickered as she watched Song He approach step by step, forgetting even to drink.
"Teacher, it's a partial differential equation!" Song He reached the stage and gave the correct answer.
Zhai Zhu looked as if she had been struck by lightning. The composure of a veteran teacher vanished without a trace, and the hand holding her teacup trembled.
"Did you figure that out yourself?" Zhai Zhu asked nervously.

If this child had truly only started learning topology at noon, then he was undoubtedly a genius! Even if he had concealed the fact that he had encountered topology before, being able to learn it to such a depth at his age still made him an absolute genius!
But... there was also a slight possibility that the child had seen the correct answer in some book.
There was only one way to verify it: see whether he dared to solve the four questions on the whiteboard. If he could solve them correctly, it would prove that his understanding of topology had indeed reached a terrifying depth!
