Reborn, I Become the Lord of the Cave Heaven

Write a novel "Rebirth, I Become the Lord of the Cave" and write about Zhou Heng's rebirth into a cave. This was opened by a Taoist ancestor, but was later abandoned. The land's aura, resources, space, and time laws are about to be annihilated. Only the final core of the cave is left. Everything is closely related to the Lord of the Cave. After Zhou Heng was reborn as the Lord of the Cave, he used some materials left by the Taoist to improve his cultivation, stabilize the cave, collect materials, repair and expand the cave, and finally became a big world. Zhou Heng also proved immortality.
