Ye Qing was dumbfounded. He hurried to the door and knocked on the stone gate, wanting to see how thick it really was. However, when he knocked, he was astonished to find that the stone gate emitted a muffled and heavy sound, indicating that it was not hollow behind it.
Ye Qing was shocked again. The sound the stone gate made was enough to prove that its thickness was definitely over two meters, and possibly even thicker. Although Ye Qing held the scabbard of The Ancestor of Miao Dao, it could only pierce the stone wall. The scabbard certainly couldn't be used to dig through this stone. Even if Ye Qing broke the scabbard, it would be impossible to break through a stone gate two meters thick!
Now Ye Qing finally understood the meaning of those eight characters he saw outside.
"Once you enter this chamber, there's no turning back!"
Indeed, as soon as he entered, the way out was sealed and couldn't be opened. There was definitely no retreat.
