Sun Ye is a well-known wild gangster on the streets of Ningcheng. He fights and collects protection fees and lives a happy life. Until one day, a "moral system" appeared in his mind, and the tasks issued were all the things he despised the most: helping an old lady cross the road, apologizing to his enemies, and acting bravely for justice, but he couldn't do anything yet. There will be penalties for failure to complete, and rewards for completion. On the one hand, he has the iron fist of the system, and on the other hand, his nature is hard to change. Sun Ye repeatedly jumps between frustration and true fragrance.
At the same time, his former childhood sweetheart Zhao Kai was jealous of his talent, connections and popularity with women, and secretly set up traps to trample him into the mud many times. Sun Ye relied on his ruthlessness and the "right path" ability given by the system to counterattack and slap people in the face all the way, growing from a street gangster to a figure who stirred up the situation in Ningcheng.
But as the system tasks escalated, he discovered that every "moral choice" he made was changing the fate of those around him. Is the system forcing him to do good, or is there someone behind the scenes? Sun Ye decided: I will set the rules myself.
