In his ninth rebirth, Ye Qin awakens the World-Eating Demon Gu and devours three thousand fellow disciples inside the Corpse Cauldron of the Yin Corpse Sect. When Leng Yueyao's sword pierces the cycle of reincarnation and Su Yingluo's Gu butterflies reveal the amber of his memories, he finally learns that the so-called ascension is a scam in which the Heavenly Dao devours people. In this life, he will use countless cultivators as vessels to raise a Heaven-Rending Blood Gu. Beneath that blood moon, formed from the compound eyes of Gu insects, he will rewrite the laws of life and death in the cultivation world.
