Fantasy: I Have Lived a Billion Lives

In my first life, I was a tree demon. I once taught scriptures to a child. Some of them became the Heaven-defying War Emperor, Canglan Emperor, and the Goddess of the Sky! In the second life, I was a cow, and I passed on the supreme immortal method to the shepherd boy who raised the cow. Later, the world called him the Immortal Emperor Mutian! In the third life, I am a sword spirit, and the girl holding the sword will become the Tailing Empress a few years later! I have taught people, plants, and monsters. They have different personalities, but they have the only thing in common. Their strength can suppress the world and shock the past! And after a billion lives, I finally returned to human form.
