People In Douluo Reincarnate For Millions Of Years

Millions of years ago, Qianyu came to this world of Douluo Continent and awakened the System. The system required that after becoming a god, he needed to be reincarnated.
After each reincarnation, the previous divine positions will be retained. After ten reincarnations, Qianyu will merge the power of the ten divine positions and become the strongest god.
Thus Qianyu began his journey to reincarnation in Douluo Continent.
Millions of years ago, a silver-haired little dragon fell from the sky and was adopted by Qian Yu.
Seven hundred thousand years ago, Qian Yu raised a black dragon.
One hundred thousand years ago, Qianyu planted a bluesilver grass.
Ten thousand years ago, Qian Yu founded a martial arts organization.
So, when Qianyu woke up from his tenth reincarnation, the black dragon he adopted became the Emperor Tian of the Megastar Dou Forest; the martial spirit organization he created became the Spirit Hall in charge of mainland martial arts; and the adopted little dragon woke up and became the Silver Dragon King, the master of all spirit beasts.
