Intentions

Yang Song raised his brows slightly and did not mind as he said, "Then, please."

As soon as Yang Song said this, there was a rumbling sound at the end of the room, then, the normal-looking bookshelf separated into two parts and revealed a passage to another room which was under the ground.

Yes, the room they were currently staying in was not the main secret room, the one under the ground was.

In fact, initially, the main secret room was the one above, but Yang Song felt it was too simple, so he just built another one under the ground.

With Yang Song's ability, it was not difficult at all to build such an underground secret room.

The underground room that he built here was even more special than the one at his home. This underground room was reinforced with many special materials, talismans, and formations too.
