The Divine Emperor has slept for three thousand years, and the laws of the Great Qian Dynasty lie in dust.
The immortal sects keep the people as livestock, while mountain gods devour their offerings. The gods sit high above the clouds, treating the laws of the human realm as worthless scraps of paper.
Baili Ji transmigrates into the Void Realm and becomes the last constable in the Sky Patrol Office tasked with escorting convicted officials. From the start, he stumbles upon the River Earl's wedding, where every girl in the city is about to become a sacrificial offering.
The defunct office has no soldiers, and no one dares to intervene.
Then the fading will of the Emperor leaves behind a secret decree, and the Yin-Yang Carving Blades reappear in the human world.
The Yang Blade, Burning Silence, incinerates the guilty; the Yin Blade, Eternal Night, apprehends souls that defy the law.
By executing the guilty, the Heavenly Laws Register can seize their cultivation, divine abilities, and fortune. But if the evidence is unclear, the blade will not fall. To forcibly borrow the authority of the Divine Dynasty, he must also offer up his own lifespan.
Starting with a river god's temple, Baili Ji patrols the realm by imperial decree, investigates immortal sects, hunts down ancient gods, and pursues the old case that caused the Heavenly Laws to collapse three thousand years ago.
Some say immortals and gods stand above all, born to rule over every living being.
Baili Ji sets his blade on the desk. "First, explain the murder."
