Tired of the grudges in the martial arts world, the peerless master Crouching Dragon Sword Immortal founded Longmen Town in the depths of the desert to take in those who had retired from the martial arts world, making Longmen Town a "Peach Blossom Spring" that martial artists yearn for. Longmen Town is isolated in the desert, and no one knows its exact location. There is only one Longmen Town Inn outside to welcome guests, which is the only entrance to Longmen Town. Wei Ping'an, a small figure in the martial arts world, is determined to live a brilliant life of "leaping over the dragon gate" and meets his confidante Luo Xiaoman in Longmen Town. Under the influence of love, Wei Ping'an has the courage to take responsibility after making a big mistake. For the sake of justice in the martial arts world and the people, he is willing to "kill his relatives for the greater good" to fight against his biological father and brothers, and finally becomes a true martial arts hero.
