Which fantasy novel described the existence of all races, but the human race was the weakest?

Primordial Heavens. "I recommend this book to you. It tells the story of the ancient primordial world where tens of thousands of races coexisted, while the human race was weak and suffered all kinds of bullying. However, a human youth had obtained Qing Tian's memories and led the human race to prosperity. He fought against other races and became the strongest race. I hope you like my recommendation.😗
