Xu Lie, a stupid thief who was born with "smelly hands", failed to open a lock once in three years. He always bumped into patrolmen when looking for trouble. He was ridiculed by the industry as "possessed by a degenerate spirit". When he was in poverty, he was about to steal for the last time but was beaten until he was unconscious. A "portable lottery system" was activated in his mind. The rewards on the wheel seem to be all rubbish - "bad luck transfer cards", "parody skills", etc., But they perfectly fit his clumsy thief physique, turning every "miss" into a well-planned trap. The system requires him to continuously complete "impossible tasks" to unlock high-level rewards. During the day, he works as an apprentice at a barbecue stall. At night, he transforms into a stupid thief who specializes in dealing with bad guys. His outrageous actions cause waves in the gray city and attract the attention of big shots. When he accidentally steals "evidence fragments" containing extraordinary power, he is involved in a melee between the system controllers and the underground kingdom. He must use the stupidest tricks to counterattack and become the chosen one who makes all system holders fearful.
