Cui Heng was transmigrated to another world and the system told him that the new world he was in was a high-grade Xianxia world. It was a world where Celestial Kings soared the sky and terrifying monsters ruled the lands.

Thankfully, the system had granted him the protection that last for 300 years. As long as he remained in the safety zone, he would not receive any damage.
