Exiling Humanity, I Was Forced to Dominate the World

Thousands of years ago, human beings were exiled to various parts of the universe and became slaves and livestock. We were used as swordsmen and I was used as fish and meat... Thousands of years later, a young man rose up out of thin air, and all races in the universe fell to their knees. From then on, the human race stood at its peak! Technology, the body, gods, magic, and immortality, the human race blooms the most magnificent fireworks among all races. This book is a bit slow to develop, and it's a bit of a hegemony. If you don't like it, don't read it. Comments and corrections are welcome.
