Hua Chenghui held a token in his hand, specially crafted by his Master.

He no longer intended to return to the outside world, planning to spend his final days within the secret realm, and thus activated the token to give others practicing the Devour-Heaven Demon Art a chance.

Some had already mastered the token, but others didn't have one at all.

But regardless of whether you had one or not, he assumed you didn't.
