So What If I'm a Mortal, My System Can Cultivate Immortality

"You mean you as a system can actually cultivate immortality!" "Right." "What about me?" "The host is a useless mortal, and it is impossible for him to become an immortal." "But the host doesn't have to worry. This system does not require techniques to cultivate immortality, there are no realm barriers, and there are no catastrophes. As long as the spiritual energy channel is enough, it is no problem to become the Immortal Emperor and Taoist Ancestor." "What about me?" Zhou Tian asked again. "With realm rubbing, the host will be as strong as this system is."
