What? I Transmigrated into Journey to the West and Became Black Impermanence?

At midnight, Chen Mo, a 22-year-old forensic science graduate student working overtime in the lab, is struck by an ancient, unidentified copy of Journey to the West. When he wakes, he has become the Netherworld's new Black Impermanence. On his very first day, he faces an absolutely hellish start: Sun Wukong has just gotten his hands on the Golden Cudgel and is about to run riot through the Netherworld to forcefully erase his name from the Book of Life and Death!

In this mythological world, where rules are ironclad and mortals are treated like weeds, Chen Mo refuses to go along with the corruption. He joins forces with Xie Bi'an, the White Impermanence, who seems laid-back but harbors a deep blood feud, becoming partners who share life and death. Together with the upright Judge Cui and the sidelined King of the Fifth Hall, he enters the Three Realms' game of strategy as a Special Case Soul Reaper.

In the midst of the crisis, Chen Mo unexpectedly awakens the hidden Netherworld Records Management System v1.0. Rather than meet the Great Sage Equal to Heaven in a head-on fight, he draws on a modern civil servant's knack for getting bogged down in procedure. Citing procedural violations, he freezes Sun Wukong's file and resolves the Netherworld's crisis without a fight. He not only earns Sun Wukong's respect, but also makes a name for himself across the Netherworld.

But this is only the beginning of his career in the Netherworld. During what seems like an ordinary soul-reaping assignment, Chen Mo's forensic instincts alert him to numerous suspicious details on the corpse. Following the clues, he is horrified to uncover a shocking case hidden deep within the Netherworld: more than three thousand suspicious deaths have occurred in Dongsheng Shenzhou. The lifespans of countless innocents have been forcibly stripped away, and their records altered, turning them into bargaining chips in deals between the demon race and forces from beyond the heavens. Behind it all lies not only a chain of corruption among the Netherworld's upper ranks, including King Song of the Third Hall, but also a plot that points ominously toward the imminent Journey to the West...
