Rebirth: Sorry, I'm the Demon Lord

I, Beichen Immortal Lord, have been fighting for the human race for more than two thousand years, but now, among the thousands of races that surround me, I have the most powerful humans. In the dim room, Xu Beichen looked at his white hands in disbelief. Yes, he was born again! This time, he no longer fights for the human race. Sorry, I just want to live happily ever after with my family. This time, he no longer cares about the world. Sorry, I only care about my own interests. From the world of high martial arts that appeared in the caves to the fairy world where thousands of races descended in the great world. This time, I, Xu Beichen, will not be the immortal who protects the human race. If you don't have a chance, you will be intercepted! If you don't have resources, just compete for others!
