章 416: Our Rolling Stone Town!

[Hint: Defensive Psalm's " Breaking the Secret Door " failed!]

[You need to master a higher level of secret door knowledge!]

Matthew was not surprised.

The Defensive Psalm could only destroy intermediate or lower secret doors, and the portal door in the core of the tree tower was obviously an advanced one.

If it was really that simple.

Spencer would have opened it long ago.

What puzzled him was that the Cloud Ruins were clearly not far from the Inn in the Cloud, and the Cloud Elves had always been known for their powerful flying abilities. Why did they have to build a portal?

" Unless they couldn't enter the Cloud Ruin through normal means."

Matthew felt that this deduction was more plausible.

At the same time.

He was also filled with fear and respect for the space behind the portal.
