My Top Professor Pretends to Be Crazy and Stupid in the Squid Game

[No harem, no routines, no invincibility, no system, no brainlessness, no cool writing, please beware if you mind. Lin Fan, a genius professor at Caiyun Polytechnic, originally planned to pretend to be crazy and act stupid to avoid prison, but he time traveled to Qi Xia, an athletic student with millions in debt, and was involved in the deadly squid game No. 456, Owing a loan shark of 3 million. Fortunately, he inherited his talent in mathematics and amazed everyone in the knockout round. Not only did he successfully deduce the password, he also... No. 001: You are a prophet, you can't hide it at all. Gangster No. 444: His eyes are terrifyingly calm, unlike an ordinary athlete. Female Academic Leader No. 067: Why do you feel like you have seen him somewhere? The familiar way of deriving mathematical formulas... When I thought I could get 100 million just by constantly participating in the game, I didn't expect that there were other purposes hidden behind the game. And Lin Fan's wife seems to be inextricably linked to all of this... Who would have thought that this crazy number 456 would be the most terrifying player in the game. Ps: This is not a Squid Game fanfic, nor is it a Ten Days End fanfic.
