Carrying a Cultivation World

In his past life, he was the youngest Immortal Venerable in the celestial realm, but was betrayed by his closest friend and perished. Reborn, he finds himself trapped in his enemy's domain. But he is not panicked, because he carries a world with him—one with billions of followers and infinite resources. In this life, he will make his enemy know what true despair is. "You think this is your world? No, soon, this will be mine."
