Cycle Envoy: Northern Revival

In this world, humans and spirits coexist. If a wandering spirit fails to reach the underworld in time to be reincarnated, it will be corrupted by the resentment of vengeful spirits and become an evil spirit. Forty years ago, the first large-scale evil spirit attack broke out in the north, and the northern underworld fell. In the years that followed, crazed evil spirits attacked across the northern lands once more. According to incomplete records, almost all of the north's reincarnation envoys were killed in battle. The region gradually became uninhabitable, and its people abandoned their homes and settled in the south.

Forty years later, Wang Yu, a young man from the south, is framed in an accident and loses his eligibility to take part in the selection of reincarnation envoys. At his lowest point, his senior fellow disciple finds him and proposes a plan concerning the north, handing him a bounty notice from the Northern Underworld. In exchange for the chance to enter the Southern Underworld's selection, Wang Yu must uncover the truth behind the outbreak of evil spirits in the north within three years. This is the story of how he discovers the truth and resolves to restore the north.
