King Youluo of the Ghost Realm and King Youming of the Ghost Realm, twins with different souls who have the same body and forever guard Naihe, control the reincarnation of the souls in the world.He is famous in the three worlds for his heroic and compassionate heart and extremely beautiful appearance. He has a close relationship with the unlucky ghost Ayin who died young, and has witnessed with his own eyes the staggering and joyful love of Yinqi.

In the ancient divine world 110,000 years ago, Ao Ge was in charge of life, while Xiuyan was in charge of death.True God Bai Jue selected Ao Ge as the Lord of the Heavenly Palace and Xiuyan as the King of the Ghost Realm when they came of age.

Seventy thousand years ago, a war between gods and demons broke out, and blood flowed like rivers.In this catastrophe, Xiuyan dispersed his soul with a military solution, stood in front of Aoge, and built a barrier for him.Ao Ge saved the last remaining soul of Xiu Yan on the battlefield and stole the Book of Life and Death.He went to the human world to experience the calamity, found the ancient true god who was in the calamity, and forcibly awakened it.

The chaotic power of the ancient true god can help Xiuyan be reborn, but in order to accumulate divine power, Xiuyan needs tens of thousands of years.This also means that during this period of time, the ghost world without the ghost king will fall into chaos.However, the ancient true god rejected this proposal.

In order to save Xiu Yan, Ao Ge was willing to give up his divine status and position as the Emperor of Heaven, guard the ghost world on Xiu Yan's behalf, and become the new ghost king.In exchange, the ancient true god condensed his soul for Xiuyan and allowed him to awaken in Ao Ge's body.

After a hundred reincarnations, Ayin was kicked into the Wangchuan River by Xiuyan, her soul returned to Wutong Island, and Feng Yin woke up.
