Who Taught Them How to Become Immortals?

Ren Changsheng, who traveled through time and was the leader of the Changsheng Sect, was very worried, but it wasn't that he was worried that the sect would be destroyed and he would lose his job. The main reason is that there is something wrong with the few female disciples he has recently accepted—— The eldest disciple has a sword body that can break magic, but when he touches the sword, it triggers PTSD, commonly known as the inner demon. The second disciple was gifted with spiritual eyes and could predict bad luck, but he lost his eyes due to an accident. The third disciple was gifted with mysterious fire by chance and was extremely talented in weapon refining skills, but he was burdened with the vicious curse of being weak and sickly. The fourth disciple... In short, the talents of these female disciples under him are rare in the world, but they always fall short in key places. But—— [Sage System]: The host can obtain system rewards through the positive reviews of his disciples. Multiple negative reviews will result in the host being sent back to the original world. In order to avoid going back to the hell life that 007 had before when he couldn't afford a house, Ren Changsheng could only grit his teeth and persevere. Many years later—— "Alchemy? Can't you practice just by grabbing a few handfuls of weeds?" "Array? Isn't this just a matter of throwing a few stones?" "Drawing a talisman? Can't it be made by simply sketching a few strokes?" "..." Facing these fairies with extraordinary skills, the entire world of immortality couldn't help but take a breath of cold air and asked one after another: "Who taught them how to become immortals?"
