Under the neon city, there is a set of absurd martial arts rules hidden. To practice hard kung fu, you have to write a letter of understanding to the object being hit, to fly with the air, you have to abide by traffic restrictions, and even to break through the realm, you have to look at the almanac markings of "it is advisable to advance diligently" and "avoid breaking through barriers". Lu Ye, an ordinary migrant worker, accidentally awakened his martial arts roots when he came home from an overtime night, but was bound to the ability of "passive avoidance of combat" - the more deliberately he seeks enemies, the more he returns empty-handed, and the more he tries to catch fish, the more he encounters outrageous martial arts incidents. He was forced to wander between the office building and the secret martial arts gym, while dealing with the boss's unreasonable KPI, while resolving absurd crises such as "square dance aunt's martial arts competition", "the best secret book in the takeout box is full discount coupons" and "the weapon stopped by the subway security check is a folding umbrella". There are no hot-blooded counterattack routines, only a way of survival based on strange rules, and the so-called supreme martial arts seems to be hidden in these ridiculous daily routines.
