Class 1 of Qingteng Middle School welcomes the mysterious new class teacher Shen Yan. He looks ordinary, but he is the "big man" hired by the principal against all opinions. After taking over the class live broadcast observation task, this "ordinary teacher" frequently "revealed his secrets" in front of the camera - he could easily solve competition problems, recite ancient poems with ancient charm, double the efficiency of code modification, and even beat the audience in sports.
The audience in the live broadcast room ranged from ridicule to shock, watching this group of self-esteemed academics being subjected to a series of "dimensionality reduction attacks", from disobedience to submission. No one knows that the true identity of this class teacher who is challenged by students every day can shock the entire academic world. A teaching live broadcast full of jokes and useful information has just begun.
