Ancestral Battle

As soon as he traveled through time, he became the heir to the down-and-out villain, and contracted a sheep as a summoned beast. I originally thought that my fate would be tragic, but who knew that this was just the beginning of the truth. Why are there so many races in the world? Are they also from time travel? Why did all the previous god emperors disappear for no reason? What does your own time travel have to do with this world? The protagonist Mingyuan will take his summoned beast and use his own power to find the answers to all this.
