The Immortal Beast Arena

Zhao Rui transmigrates to a world much like a xianxia setting. But he discovers that many people from other worlds have transmigrated there too. They can plunder one another's memories and bloodlines, and may even possess one another's bodies. In this world, which is like a fighting arena, Zhao Rui uses various secret identities to travel through one small world after another, searching for the ultimate answer.
