When Jiuyou rebelled against his fate, Yun Ji went crazy and cut off the chain of heaven with one sword, staining the three thousand realms with blood. Hundreds of sects knelt down to worship, the immortals and Buddhas lost their voices, and no one dared to speak their names. But no one knew that the source of his madness was Yu Lin, who was suppressed in the depths of the Nine Netherworld by his own hands - a former sect member, but now a traitor to his fate. When Yu Lin opened his eyes, Yun Ji's madness and obsession were reflected in his pupils, and the fate of the two truly began to reverse. It's not who saved the other, it's the lunatic and the prisoner who used their lives as a contract to tear open the hypocritical cloak of heaven.
