Hidden in the metropolis, Yang Fei lives as a legend. The Magic Shadow Assassin and King of Soldiers—a classified operative serving an elite special forces unit on an undisclosed mission. Armed with devastating combat skills and military precision, he wages relentless war against the darkness, crushing demons and ghosts that lurk in the city's shadowed corners. In the urban jungle's ruthless survival games, only the strongest prevail—and Yang Fei reigns supreme. He is the warrior king of all terrains. But even unstoppable soldiers cannot escape their obligations. When his landlady corners him, demanding the eight hundred yuan owed in rent, the legendary operative faces an enemy he cannot defeat with fists alone.
