Cultivation in a Fantasy World to the Point of Becoming Possessed

(This is my first time writing, so I may be more free-spirited) =gb= Chapters marked with "." Are chapters where the male and female protagonists interact a lot, but starting from the third chapter, the two of them have been getting tired of each other. The first chapter is about childhood. It is recommended to start reading the important plot and the emotional story of the male and female protagonists from the third chapter (^^)/ A female essay. The heroine is chic and pursues whatever she wants, a bit yandere. There is a male protagonist who is a little bit beautiful but is trying to be optimistic. The male protagonist takes the initiative in the early stage, and the female protagonist is strong in the later stage. There will be a plot where the female protagonist bullies the male protagonist, but it's still quite sweet so far. The spiritual energy in the modern world is weak. Leng Qianchen, as the last disciple of the "Qing Medical Sect", the only sect of immortal cultivation, has been practicing hard but can only stop at the Qi training period. Even when he died saving a forest fire at the age of twenty, he still could not open the Najie that contained all the belongings of the sect. When he opened his eyes again, he had traveled to a fantasy world and became an eight-year-old child named Gu Mo in a small town. A system appeared in his mind. "Our mission is to transcend everything and become the best women in the world!" Looking at this world with extraordinarily abundant spiritual energy, she couldn't help but burst into tears. She clenched her fists and inspired to become the first person to cultivate immortality in another world! After finally cultivating her foundation and opening her ring, she fell into deep self-doubt when she looked at the contents inside - "Scientific Guide to Obsessing with Demons", "Original Demon Cultivation Secrets", "Seven Voodoo Sects" and "Eight Hidden Weapon Sects". Isn't it the sect of immortality that I joined? How come each of the techniques is weirder than the last?
