Lin Chen accidentally awakened to the "Nine Turns of Body Tempering Technique", but was ridiculed in a city where martial arts was popular because of his ordinary family background. Until he met Su Muxue, the daughter of a martial arts family, who not only saw through his potential, but also rescued him when he was surrounded by bullies.
During a black market transaction, in order to protect Su Muxue, Lin Chen forcibly ran the Body Tempering Technique and defeated the Body Tempering Realm master with one punch, but the secret of the technique was exposed. Since then, various forces have swarmed in: the martial arts academy wants to win over him, the dark organization wants to seize his skills, and even the bullies who bullied him in the past have invited strong men to take revenge.
Faced with many crises, Lin Chen no longer hides his edge. He used the Body Tempering Technique to overcome all obstacles and counterattack step by step from a street boy. Not only did he want to protect Su Muxue and his family, but he also wanted to temper his body and become a saint in the reinforced concrete city, creating his own legend of the God of War!
