The protagonist, Shi Huang, is a wilderness survival expert who has been struggling to survive in the primitive jungle for more than ten years and is almost out of touch with modern society. After being found back in the city, he discovered that there was an inner world hidden in this steel forest where martial arts was the most important thing. Without a system, without an old man, Shihuang's only "golden finger" is the terrifying body that has been tempered by nature and has already exceeded the limits of the human body.
He doesn't understand complicated moves or the so-called internal skills. His fighting methods are only the most primitive biting, charging and beating. While the geniuses of the ancient martial arts family were still complacent about their exquisite boxing techniques, Shi Huang had already used the purest violence to tear all the rules into pieces. His appearance was like a prehistoric beast breaking into the sheepfold, telling the entire urban martial arts world with absolute power: all techniques are fragile in the face of the true survival instinct. The highlight of the main plot is that the protagonist uses the most primitive, most brutal, and most unreasonable "flesh-style" fighting style to constantly crush and subvert the cognition of traditional warriors, bringing about the ultimate violence.
