But at the beginning of his new life, he encountered He Lanzhuo, a ferryman who held a strange contract and claimed that Jiang Li’s “rebirth” was still unfinished business for the Underworld. One longed to break free from the past, while the other was determined to pursue vanished souls. Bound tightly together by the netherworld, they were forced to join hands at the boundary between the mortal world and the afterlife, and uncover the secrets buried deep within reincarnation.
