Back in the day, Han Shikun was the most powerful man in Qingjiang City. He adopted two children and passed on his business acumen and knowledge of the occult to the elder, Chen Weichao. Before Han Shikun died, he divined that his younger daughter, Ruan Qianqian, would face a calamity that threatened her life. For revealing Heaven's secrets, he was taken into the Underworld by the Nether God Xu Wei. Ruan Qianqian and her husband also met with disaster and were taken into the Underworld by the Nether God Xu Wei, leaving behind their son Wen Zhejun, who was born under a pure yin birth chart. To save his family and bring them out of the Underworld so they can enter the cycle of reincarnation, Chen Weichao takes Wen Zhejun as his apprentice. Wen Zhejun helps people who died mysteriously fulfill their wishes and assists the police in solving cases, hoping to earn his family's release from the Underworld and their passage into the cycle of reincarnation. Along the way, he meets Shen Xiaomi, who was born under a pure yang birth chart. The two go from disliking each other to falling in love!
