The Delivery Guy's Martial Arts Comeback in the City

In a bustling city, food courier Liu Jiang leads an ordinary life until he unexpectedly gets caught up in underground fights. Because he is a skinny delivery worker, everyone looks down on him and assumes he will lose in no time. But Liu Jiang awakens an ability that makes him stronger the harder he gets beaten, setting him on the road to a comeback. He easily defeats his opponents in the ring, catching the attention of a black-market boss. The boss sees him as a thorn in his side and sends men after him with guns, but Liu Jiang takes bullets to the face and rebounds them at his attackers. Though he wins, the boss puts a bounty on him, leaving him in grave danger. Meanwhile, his status as a delivery worker makes it difficult for him to establish himself in the fighting world. Can Liu Jiang break through the class barrier, survive in this hostile environment, escape the boss’s pursuit, and become an urban legend? The answer remains unknown.
