I Bind the Yanjun System to Suppress Ancient Souls

Transmigrated as a temporary worker in the underworld, facing the mess of the missing Yanjun and the collapse of the six paths of reincarnation. Wandering souls run rampant, ancient powerhouses refuse to enter reincarnation, yin and yang are imbalanced, and the three realms are on the brink of collapse. Binding with the Yanjun System, Jun Bufan embarks on a hardcore law enforcement path—not relying on fighting, but strictly following procedures, with all twelve steps of reincarnation paperwork mandatory. He slaps down the Heaven-Swallowing Ancestor, forces registration and clocking in, and records everything on video for the archives. Using rules as a blade to suppress ancient souls, and procedural justice to reshape the order of the underworld. While others cultivate immortality, he handles cases; with the system in hand, all the big shots queue up for reincarnation. This underworld, I have the final say! — Description from novelcodex.org
