Gu Changsheng cultivates painstakingly for ten years, becoming the one and only Golden Immortal under heaven. But to break off an arranged engagement and search for his first love, he descends the mountain. He conceals his identity, posing as a lowly bodyguard. Along the way, he uses the strategy of "feigning the pig to devour the tiger"—crushing arrogant young ladies, defeating prodigies who come to challenge him, protecting the princess and the empress dowager, and wiping out the rebels of the three great clans. Even the deity he once guided must bow and submit. On the surface, he seems a simple bodyguard, but in truth he is a Golden Immortal descended to the mortal realm—one punch destroys enemies across the world, protecting everyone by his side, before settling his mortal karma and stepping onto the path to find true love!
