I Lived for a Billion Years in a Fantasy World

In my first life, I was a tree spirit. I once recited scriptures to a child, and some of them went on to become the Heaven-Defying War Emperor, the Canglan Great Emperor, and the Goddess of the Firmament!

In my second life, I was a cow. I passed supreme immortal arts to the shepherd boy who raised me, and in time, the world called him the Immortal Emperor of the Heavens!

In my third life, I was a sword spirit, and the girl who wielded me became the Supreme Spirit Empress years later!

I have taught people, plants, and demons. They had different personalities, but they all shared one thing: their strength reigned supreme in their age and shook the ages!

And after ten billion lifetimes, I finally returned to human form.
