My name is Chu Fan. On the surface, I am a security guard in the upscale community "Yunding Tiangong" who sleeps all day long and practices Tai Chi for health care for the elderly. But in fact, I am the only heir of the "Truman" family, the pinnacle of martial arts, who has been trained in the mortal world. My mission is simple: use the most humble identity to experience the most real world and sharpen the heart of a warrior. I originally wanted to live in peace and quiet for the past few years, but there was a cool CEO, a tsundere school beauty, and an eccentric female athlete living in this community... And troubles followed. From school bullies to underground boxing champions, from business rivals to martial arts sects, they all thought I was just an ordinary security guard who could fight a little. And I can only use "health Tai Chi" that they can't understand in front of them again and again, and perform "side push" operations that make them doubt their life. The most important thing is that when I can't solve the problem with my fists, standing behind me is the order of the entire martial arts world. I, Chu Fan, have the strongest connections in history, a master tactician dedicated to solving the biggest troubles with the smallest effort.
