Recommended a Friend's New Book "Human Immortal Emperor"

There are five grades of immortals.

Heaven!

Earth!

Man!

God!

Ghost!

Heaven and earth are both precious, while gods and ghosts are ethereal. I only want to suppress the heavens with martial arts and become the supreme ruler of the world!

I am also an old author... Basically, I can trust my integrity and I can kill without any worries...
