An overtime takeout order, a deliberate attempt to make things difficult. Lin Xiaole accidentally fell into the sewer to avoid the rain, but found an ancient secret book tightly wrapped in oil paper. It's not martial arts, it's "Jokes and Cheats". The warning on the title page is not "You must first commit suicide", but an even weirder "You must first be thick-skinned"!
When he relied on secrets to transform himself from a humble deliveryman into a man of great concern, he did not know that he had stepped into a thousand-year chess game. The true meaning of the joke and the titillating ultimate point all point to an ultimate mystery that can rewrite the course of human civilization.
See how he carries out the most heroic mission in the most unorthodox way!
