Mu Yun, an orphan who fell into the sect, returned with a broken body of chaos and a god-killing spear spirit, and awakened the memories of his past life in the blood-moon rift. Bai Li, the ninth princess of the Tianlan Dynasty, plays the harp to control the mountains and rivers during the day, and holds the whip to lead the underworld at night. Underneath her dual personality lies the forbidden secret of completing the way of heaven. When the three dynasties compete for ancient relics, the demon clan starts blood sacrifices, and the demon clan covets the gap in the heaven, Mu Yungui discovers that the so-called "mending the sky" is actually a scam by the upper world to harvest billions of living beings. Using the god-killing spear to tear apart the starry sky, and using the power of chaos to recast reincarnation, this fateful duel spanning seven lifetimes will eventually inscribe a new law of heaven on the broken bronze compass - "I am the variable."
