Chen Mo and Su Wanqing huddled in the underground streets of the Steel City. This was the abandoned place of the martial arts alliance, where Bone Tempering Realm warriors could run rampant, and mutilated limbs and blood stains were the daily scenery.
An accidental leak of evil energy allowed Chen Mo to awaken the "Martial Veins Analysis" system, which can see through the flaws in moves and dismantle evil techniques. However, Su Wanqing, who has Lingyun bloodline, was falsely accused of being a container of evil energy and was about to be "purified" by the alliance.
In order to save his best friend, Chen Mo clutched the rusty steel pipe and stepped into the underground boxing ring: one punch shattered the knee of the Bone Forging Realm, he dismantled the killer move of the evil warrior with his bare hands, and exchanged blood and sweat for Qi, Blood Pills and training resources. "Either you stand in the ring until the end, or you rot in the gutter!"
When the alliance's pursuers trampled the underground streets, Chen Mo finally understood the true meaning of the system - analyzing the martial arts of all things and transforming the street art into a peerless magical power. As a handyman, he defeated the genius of the family, tore apart evil puppets with his own hands, and beat him all the way from the underground boxing ring to the alliance headquarters.
The secrets of Su Wanqing's bloodline, the ancient inheritance of the underground streets, and the shocking conspiracy of flooding with evil energy emerge one after another. The two low-level warriors will eventually smash the unfair order with their fists and reach the top of urban martial arts!
