Ling Han, the leader of the martial arts alliance in Tianyuan Continent, was besieged by his old enemies and triggered the Chaos Heavenly Tribulation to die.

Faced with the triple shackles of technological civilization, a weak body and a poor family, Ling Han used the "Hidden Dragon System" as a guide to rekindle the fire of martial arts in the reinforced concrete jungle and start a counterattack that subverted cognition.
