The five realms of Xuancang Realm coexist, and martial arts are prosperous but the rules are broken. The weak and the strong are the unchanging laws. Ye Chen, the chief disciple of the Qingyun Sect, the first sect of the righteous path, was a once-in-a-century genius in cultivating immortals with a bright future. However, his senior brother Lin Feng and the third elder Zhao Tianxiong colluded with the demonic Blood Soul Sect to betray him. More than 3,000 members of the sect were massacred. When he was on the verge of death, the master used his life essence and blood to protect his remaining soul, escaped into the forbidden cave of ten thousand corpses, and used forbidden secret techniques to fuse the ancient holy bones of the way of killing to create a body of the way of killing, leaving behind the "Book of Ten Thousand Killings".
The path to immortality was cut off in the past, and Ye Chen awakened to the path of killing in the sea of blood on the mountain of corpses, vowing to prove the path through killing, and pay with blood! Killing can absorb cultivation, condense killing souls, and forge the foundation of the Tao. Although he was counterattacked by heaven and hunted by thousands of tribes, he climbed up step by step by killing disciples, masters, and kings. He was invincible at the same level, and lower levels defeated higher levels.
On the way to seek revenge, he encounters Su Qingyao, an undercover agent from the Immortal Realm. She was originally ordered to investigate the Taboo Killing Path, but through repeated confrontations and secret assistance, she got a glimpse of Ye Chen's true intention of "killing evil rather than killing good", and she went from being suspicious and wary to fighting side by side. The two work together to sneak into the old site of Qingyun Sect, hunt down traitors, expose conspiracies, and stir up trouble in the five regions.
From the "killing ghost face" who returned from the cave of ten thousand corpses to the supreme murderer who shocked the three realms, Ye Chen used thousands of souls to cut through hypocrisy, used ten thousand corpses to suppress the prison and resist the law of heaven, and used killing to stop killing and protect the common people. Faced with the righteous encirclement and suppression, the demonic covetousness, and the shackles of heaven, he and Su Qingyao went all the way to unlock the secrets of the killing order, fight against the evil spirits outside the world, and finally broke the shackles of the rules and became the ancestor of the killing Tao recognized by all the worlds, composing a passionate legend of "If the way of heaven is unfair, I will kill the way of heaven; if all the worlds refuse to accept it, I will kill all the worlds"!
