A boy named Zhang Jiao's village is attacked by a mass quantity of corrupted Han Dynasty soldiers. Everyone in the village is killed including his parents... The only ones who survive are himself and his 2 brothers, Zhang Bao and Zhang Liang. Together they form a religious taoist sect, and with their words, find a few followers... It is just a little later on down the road when Zhang Jiao is 34, that he and his brothers hear a voice. This mysterious voice tells them to gain more followers and to swallow 3 mysterious shadow balls. As they believe the voice is of their god, they obey the instructions given to them. The voice was not that of a god but that of a monster... Through swallowing the mysterious black ki balls, they gave the beast the ability to posess them, and use its magic power through their bodies. The beast gains many followers through its magic powers and attempts to destroy the han empire with its power.
