After the war between the demons and demons, Emperor Runyu issued an edict to trap himself in the Xuanji Palace and tied himself to the bed with immortal locks in order to resist the mental erosion of himself by using the forbidden technique Qiongqi. The Demon Lord, who was the Fire God Xufeng, the former second highness of the heaven, read this edict and realized that his brother actually wanted to die with Qiongqi, so he rushed to the heaven, holding the Red Sky Sword, and used the glazed pure fire to purify Qiongqi and save the Emperor of Heaven. However, in order to save Jin Mi, the Emperor of Heaven sacrificed his own cultivation and transferred half of the immortal roots to Jin Mi with the forbidden technique of Blood Spirit Son. He was seriously injured in the battle with the demons and struggled to deal with the things in the heaven that had been abandoned for a long time. Twenty thousand years later, he fell ill and was diagnosed by Qihuang Immortal Official. Now he only has less than 10,000 years of immortal life left. The heaven was shocked when he heard this. Now Emperor Runyu has worked hard to govern since he succeeded to the throne. The six realms are peaceful, and the fairy world is in order, with no more intrigues. Some immortals with profound cultivation even ascended to the sky during this period. Now that the Emperor of Heaven is seriously ill, everyone in the Heaven Realm is working together to find a cure for the Emperor of Heaven. Xu Feng Jinmi has had a lot of feelings since he came down to earth. He knows how difficult it is to run Yu, and he also feels that he owes Run Yu too much, so he begins to order the Demon World and Flower World to work together to find someone who can cure Run Yu. Doumu Yuanjun was grateful for Runyu's merits in helping the righteous path, and used the water of the pure pond to help Runyu recover part of his cultivation. The three worlds worked together and finally learned that there was only one person in the world who could save Runyu.
