Lin Yan, a social worker, died suddenly while working overtime. His soul went to the underworld and he awakened the memory of his past life - he was once the envoy of reincarnation. He was framed for changing his life to save good people. He has returned from reincarnation after hundreds of reincarnations.
With his eyes open and understanding of yin and yang, the soul judgment pen in his hand, and the seal of reincarnation appearing on his chest, he refused to be judged and returned to the world, vowing to settle old grudges and reestablish the order of the six realms.
There are undercurrents in the city: evil ghosts hurting people, evil cultivators seizing souls, and rebellion in the underworld. He uses his pen as a blade to suppress lonely souls, kill evil spirits, and punish evildoers. He obeys orders in black and white, and bows his head with an ox-headed and horse-faced face.
From a mortal mortal to the master judge in charge of reincarnation, in this life, he wants to make good and evil be rewarded, and life and death are up to me!
