Su Chen's gaze was attracted by a yellowed ancient book. His expression changed as he took it out.
"Infinite Expanding World?"
Su Chen glanced at the cover and muttered softly.
At first, he thought that it was just an ordinary cultivation method.
After all, higher-grade divine powers or cultivation methods would usually be recorded in jade slips.
However, this Infinite Expanding World was recorded on a piece of paper. No matter how one looked at it, it was not a high-grade cultivation method.
However, after Su Chen casually glanced at the content, his expression gradually became solemn.
This Infinite Expanding World was not a cultivation method, but a secret technique!
It was the secret technique that the black-robed man had used at the final moment!
Just as its name suggested, this secret technique could create a world of its own.
It was called a world, but in Su Chen's eyes, it was just a domain.
