Chu Nan obtains a spirit pearl and has his soul transported into the Great Qin, a world shared by humans, demons, and ghosts. He becomes one of the four Guardian Envoys of the City God Office, and the nominal husband of Ying Xi.
After he's ambushed and wounded, the spirit pearl hidden inside him awakens. He becomes a Soul Guide and learns the Great Dao Reincarnation Art. Then, after performing "A Laugh in the Proud World," he awakens a yang soul: the Judge's Brush and the Book of Life and Death.
He thought he would become an unrivaled powerhouse from then on. Unfortunately, his skills are pathetic and his damage is practically zero, so all he can do is support. But his nominal wife, the Guardian Envoy, has off-the-charts combat strength and is especially good at physically exorcising spirits.
From then on, Chu Nan becomes a low-ranking clerk in the City God's Office of Rites, embarking on a sweet co-op adventure with his nominal wife, one that leaves them fleeing in terror.
However, the more he learns about this world, the more the tangled grudges between humans, demons, and ghosts come to light, along with the calamity that struck a thousand years ago. Faced with a choice between personal love and the greater good, Chu Nan calmly accepts his fate.
