The Emperor of the Heavenly Realm and the Demonic Lord of the Demon Realm both fell into the Wangchuan River. When they descended to earth and experienced calamity, they became brothers and sisters with no blood relationship. Because of some things, the two came to Dumang Hall.
In getting along day after day, Xu Yi'an didn't know when his heart was moved. But Xu Yuerong had already taken the Forgettable Pill when he was the Demon Lord and didn't know about love.
After going through many things, Xu Yian learned the identities of him and Xu Yuerong. After learning that only one of them could live, they had to let the other person kill him, and Xu Yuerong had an uncontrollable magic power in his body. Once it broke out, life would be destroyed. When it was not under control, Xu Yian chose to feign death and use forbidden magic to exchange the spells of the two of them.
He broke Xu Yuerong's heart until he faced his imminent death and decided to die.
Intention: I love you so much, but you deserve better...
