Gatekeeper of Parallel World

The gatekeeper of the parallel world, he is immortal and lives as long as the heaven and the earth. Guarding the balance is his natural mission, and killing people is his bounden duty; He is cold and ruthless by nature, but he cannot escape the hundred-year cycle of reincarnation. The love debt in his previous life makes him trapped in the earthly world again; Faced with the intrigues, grudges, and grievances of the human world, as well as the looming controller behind the parallel world, where should he go? Only in the end did he understand what "person" was! What "god"! They are all just "livestock" in captivity!
