The protagonist travels to a different world where the "teacher's way" is respected, and becomes a useless teacher in a low-end college. A "library of creation" awakens in his mind - as long as he observes any person or object, the library will automatically generate the corresponding "Book of Heaven's Way", recording all its flaws and flaws. He teaches and educates people by pointing out flaws and correcting them, counterattacks and slaps people in the face, and finally reveals the eternal secret of "the flaws in the way of heaven".
