For three thousand years, I only hope that the world of mortals will not be immortal. What does that mean?

It means you don't want to be immortal. Immortals have no personality, which is the so-called forgetfulness of heaven. I just want to experience all kinds of joys, sorrows and fears in the world of mortals, and finally become a demon and live a happy life from now on. Magic is a kind of carefree. The fairy is high above, and all causes and effects do not touch themselves.
