The spiritual source has run dry, evil spirits run rampant, and the age of law’s end is approaching. Mortal monks struggle simply to survive. Gu Chen, a mine slave, stumbles upon a priceless Stone Mill—a relic capable of grinding all things, purifying spiritual liquid, and devouring an enemy’s cultivation for his own use. Seizing the chaos of a mining accident, he fakes his death and escapes, slipping into the Qingyang Sect under a false identity as a timid servant. Cautious to a fault and merciless in combat, he uses both wit and strength to rise steadily through sect rivalries and external threats. As his power grows, a staggering truth surfaces: the lower world is nothing more than a spiritual field cultivated by immortals above, and its countless creatures are merely nutrients for their harvest. Refusing to be reduced to a sacrifice, Gu Chen rallies allies of all kinds and wages war against the distant, indifferent Tiandao Shepherd. In the end, he activates the Kuron Dao, grinds away the old order of heaven, and ushers in a new age—taking the name Taoist Taichu.
