Start: Invincible, met the empress's apprentice

[Invincible + Decisive to Kill + Cool + Apprentice of the Empress + Dark + Funny + The Protagonist Has No System! ]
Tens of millions of years ago, Li Baiyi met a girl and a big yellow dog. Tens of millions of years later, the girl unexpectedly became the Empress of the Immortal World, and the big yellow dog has become the Dog Emperor in people's mouths!
Millions of years ago, Li Baiyi passed by a river and enlightened a koi. Unexpectedly, he became the Dragon Clan's Ancestral Emperor in the future!
Even if he just urinated on the side of the road, a million years later, a tree became the tree ancestor worshipped by local people, and a grass became an existence that could kill the emperor!
Li Baiyi has been walking around time since the beginning of chaos, stepping on the long river of time and exploring the land of reincarnation. No one knows how long he has lived, but they only know that he once created the dark era of the emperor's fall!
And Li Baiyi did all this just because he wanted to find a truth.
One truth about where he came from. The other is to find a wife!
