"Right behind my butt! Is it some kind of pervert?" The Fatty covered his rear, feeling a chill on his backside.

The others saw it too. The Fatty's name was on the second-to-last line, and below it was the name that had been erased.

A few seconds later, he closed the notebook, having reached a conclusion.

"Brother Chu, what'd you figure out?" the Fatty asked expectantly.

Chu Changge said, "This person appears repeatedly, so they must have a special identity. They show up often enough to have been involved in the instance from the very beginning, and they must know this place well."

The Fatty nodded eagerly. "So this person knows a lot of important information? If we find them, maybe we can learn how to leave the instance."
