There are people with super powers in the world who are descendants of ancient gods. They have the responsibility of maintaining the balance of yin and yang in the world and guarding the six realms. The world respects them as Zikui. Purple is the color of authority, and the leader is the color of leadership. Zikui means the head of all things.
Su Mo rescued the seriously injured Zikui by chance. In order to repay the kindness of saving his life, Su Mo was willing to take him to the marrow washing pool of the gods to wash away the turbidity on his body and transform him into an immortal.
Although he was at the top of the immortal world, she was the only one he could never forget. He had no choice but to respect her. His obsession drove him crazy, and he turned into a demon and caused chaos in the six realms. In order to save the common people, she sacrificed her body to quell the chaos. But she never looked at him.
Desire is the root of all evil. Desire can lead to immortality and devastation. It is heartless and desireless. It is difficult after all.
