During the Wulin Assembly, Blood Demon Luo severely damaged groups of heroes. The leader, Huo Changkong, lost half of his moves in the decisive battle. Huo finally injected his power into the young Liu Jing and protected him from evacuation. Fourteen years later, Liu Jing, who claimed to be talented, wanted to learn from Kung fu masters, came to the "Huo Boxing" by chance. Master Huo, the owner, allowed him to take the fighting challenge, but Liu Jing failed and had to leave. On the street, Liu Jing met another ace, Tang Baibai, and followed him in search of the one-of-a-kind master, but came to the secret grid of the Black Feather Society and met the Blood Demon.
