Feng Jun sank downward, descending more than fifty meters before suddenly feeling the ground vanish beneath him.
Then he discovered that he had fallen into another stone chamber, nearly identical to the one above.
The only difference was that this chamber was not empty. A formation disk was operating inside it.
