The heroine Jiang Niannian has the temperament of Chaos Yuanqi. She has twins who inherited Chaos Yuanqi at the age of 5. The boy Shen Xiaobai, the daughter Shen Xiaoyue, and the husband Shen Yifei are people who balance yin and yang. They have been cultivating immortals for many years, but have not acquired high-level skills. She is depressed and unhappy. When she meets a slave of the devil, he offers an olive branch. All he needs to do is sacrifice 5 If you have children at the age of 18, you can obtain the high-level skills of the demon clan. Shen Yifei was ruthless and tricked his wife and children to the altar, knocked his wife unconscious, and sacrificed his children. When the Demon King appears, as long as he absorbs the Hunyuan Qi of the dragon and phoenix twins, he can practice magical skills that can destroy the world. The heroine travels to Jiang Niannian, wakes up and snatches her children. With the blessing of the system, she takes the souls of her children to the secret realm. At this time, the devil has divided the chaotic energy and absorbed the yin energy of the dragon and phoenix twins. The children who were taken away only have yang energy. The devil uses the children's bodies to extract puppet dolls, inputs the yin energy into their bodies, and gives them to Shen Yifei for a period of 10 years. Within the year, the child must be captured, the yang energy must be fused for him to absorb, and high-level magic cultivation techniques must be taught. Jiang Niannian's system reminded that with the skills merchant, you can kill monsters to get exchange points, exchange them for skills, and give the skills to others. The cultivation of others will be fed back to you, and if others use the skills taught by you to kill monsters, you can also get exchange points. Before Jiang Niannian traveled through time, he was an avid fan of novels. The exercises in the Kung Fu Store were all from the novels he had read in this world. Moreover, Jiang Niannian had a fierce personality. She was a Sichuan girl who founded a sect, recruited disciples and raised children, and changed the names of her children to Jiang Xiaobai and Jiang Xiaoyue.
