Mortals Take Parasitic Beasts on Their Journey to Immortality

True MortalNo System In the world of immortal cultivation, it is already miserable enough for a mortal without spiritual roots! He encountered another parasitic beast that was dying and trying to parasitize him. Why was it so miserable? What to do? Work together? The combination of weak and weak = strong? How to get rich without spiritual roots? Can this mortal still establish a sect in the world of immortality? I can't think about it well, it's too difficult. I'm asking for some advice from capable people and experts from the immortal world.
