In Qingyang Funeral Home, Lin Qiubai, the successor of corpse exorcism, and Ah Yue, the witch saint's saint, met due to the blood moon corpse transformation and formed a blood contract of life and death. Facing the resurgence of the evil god and the siege of the righteous path, the two carried the book of life and death to break into the Miao village, defeat Kunlun, and fight against Nanyang. In the entanglement between the Yin and Yang worlds, they used love as a blade to break through fate, open a Yin and Yang inn, and protect the souls from resting in peace.
