I Cultivated for a Billion Years, and You're Telling Me I'm Just Reborn?

Chen Xinghe transmigrates to an ancient, primeval era.

He also awakens a sign-in cultivation System. Signing in day after day grants him cultivation and rare treasures, including miraculous artifacts and secret manuals of divine techniques.

On his first day after transmigrating, a terrifying monster nearly eats him alive. From then on, he firmly sticks to the rule of keeping a low profile while growing stronger.

He signs in and cultivates day after day. But when Chen Xinghe finally emerges from seclusion ten billion years later, eager to see the new world, he is stunned.

Gazing at the towering buildings and bustling streets, Chen Xinghe immediately explodes.

"System, get out here! I spent ten billion years signing in to cultivate immortality, and you're telling me I was only reborn on Earth ten billion years ago?"

This is the story of an immortal cultivation powerhouse who returns to the modern city after cultivating for ten billion years.
