Mu Li, a genius doctor from the twenty-first century with the same name, transmigrates to the Qilin Continent. By a stroke of luck, she obtains the cultivation spirit stone that everyone yearns for, rapidly increasing her strength and allowing her to reach the Nascent Soul realm with ease, a level others struggle their whole lives to attain. She also brings her modern medical skills and an inexhaustible medical space, where she heals the sick and saves lives in another dimension.
After transforming herself completely and easily climbing the towering Cangzhu Mountain, she swears to send every person who ever hurt her straight to hell.
But in the end, she discovers that the person who made a solemn vow with her in childhood was not Mo Yuhan, but Mo Tingsu, whom she killed with a single palm strike.
Her father and Yao Lishuang were killed by Mo Yuhan, the man she trusted.
Mo Yuhan sheds his false facade step by step. To seize the position of heir, obtain the Demon-Suppressing Bottle, and unite the three realms of humans, immortals, and demons, he does not hesitate to kill his own mother and Mu Li's father, who treated him like his own son. He exploits Mu Li's love for him, all to become the overlord of the three realms.
The cycle of heavenly justice turns. Mo Tingsu is reborn through nirvana, rising to the top after being driven to the brink of death and entering the realm of the Nine Heavens Immortals. When he saves the dying Mu Li, he realizes from the way their eyes meet that the woman before him is not Mu Li.
What fate awaits Mo Tingsu, Mu Li, and Mo Yuhan?
