Chapter 4579

Cheng Yu took four pieces of paper and began to repair the area painted by elder fan and the three of them carefully searched for other clues in the hall.

Although they all think that the secret hidden on the stone top of the main hall is the mechanism to open a new way out, this is just their guess.

At most, this kind of speculation is more likely, and they are not 100% sure that this is the secret of the agency.

However, although the hall is very large, the clues they can provide are very limited. They also made different attempts to the mechanisms designed by the former halls, but the results were very disappointing to them, and no new exits appeared.

This time, Cheng Yu spent no less time than before. Although we already have a base map in hand, it's quite a long time to compare one by one.

It took about four or five hours for Cheng Yu to get a complete drawing of the stone top groove.

Just looking at this drawing, he still didn't see what it meant!

"Young master, it's not much different from what we made before. It's still in a mess. Can't you see what's going on in Ming Tang?"
