After searching for a while without finding the mechanism, Yan Dan secretly breathed a sigh of relief. He waved his hand and said, "Withdraw! Leave two men to guard this cave!"
This was a precaution, in case they hadn't found the mechanism, but it actually existed. Since the others couldn't remain in the secret passage forever, they would eventually come out.
This approach was flawless, and if their master later questioned them, they would bear less blame.
After all, appearances must be maintained!
So, two unlucky ones were left to guard while the others left to search elsewhere.
You'er stood below the stone slab. Generally, given the thickness and distance, he shouldn't have heard anything, but he still did.
This was why Li Qingmu had asked him to come over and investigate.
You'er was naturally sensitive, attuned to many things.
