I Am Cultivating Immortality Steadily Among Mortals

My name is Chen Xuanyi. I am very panicked now because my soul suddenly died while working overtime and was reincarnated into the cruel world of mortal cultivators. My mother died when I was five years old, my father died when I was twelve years old. Not to mention the evil star, I finally detected the spiritual root, but it is still a false spiritual root. I thought I could use the help of knowledge. It would be fine to get some benefits from Xiao's plot or to hang out with the protagonist's thighs, but I didn't expect that what I came to was actually the Sea of Chaotic Stars. It was almost two hundred years before Old Demon Han arrived. With my talent, let alone forming pills and building foundations, it was quite difficult~~~~ Without background and plug-ins, is it really impossible to become an immortal? Well, it's not that there are no cheats. Chen Xuanyi thought, how could the countless novels about cultivating immortals and knowledge of mathematics, physics and chemistry in his head not be cheats?
