On the night of the blood moon, Jiang Jin raised his sword and beheaded the sect leader, but was shocked to find that the head was still whispering. He was not a traitor who killed his lord, but a chosen sacrifice. In order to uncover the mystery of the sect's thousand-year blood contract, he teamed up with the deposed saint Yu Zhao and sneaked into the blood eye of the earth. However, he triggered the backlash of the guardian Ling Xi, the hunting of the righteous daughter Bai Jinyuan, and the blood curse buried for hundreds of years by the mute slave Qi Mu. When the old crippled prophet's copper coins were shattered into ashes, Jiang Jin understood: it was not the sect leader who was killed, but the mirror image of his own destiny.
After Jiang Jin killed the sect leader, the blood moon did not fade away. Instead, it tore the sky apart, exposing seven bloody eyes underground. Yu Zhao used the "Moon Soul Sutra" as a guide to force Jiang Jin to face the truth of the blood contract in his body - he was originally the 'vessel' cultivated by the sect master to resurrect the ancient god. In order to save the soul of his family, Ling Eo activates the forbidden technique to graft his soul into Jiang Jin's sword. Every time he fights, he loses a piece of his memory. In the end, he only remembers Jiang Jin as 'the child who didn't cry'. Qi Ya used the blood eye resonance to detonate three earth veins, causing civil strife in the sect. Bai Jinyuan took the opportunity to usurp power, but in the backlash of the blood curse, he gradually realized that he and Yu Zhao had the same origin. On the last night, the old lame man stuffed copper coins into Jiang Jin's palm and said softly: 'Are you going to kill him, or you tomorrow? 'The blood moon is approaching again, Jiang Jin holds a broken sword in his hand, Yu Zhao stands on the top of the divine pillar, Bai Jinyuan raises his sword to kill, but the corroded soul fire is extinguished inch by inch. The sect is not destroyed, the blood contract is not broken, and the real sacrifice has just begun.
