158: Dark Tower!

"A Tower?" Lin Xian thought and immediately approached.

"There's something strange about this tower, husband!" Fei Ran said while looking at the tower that always emits black steam.

Lin Xian felt the same way and immediately asked the System. "System, is there something of value in there? And what kind of steam is that?"

[DING!]

[The System can't detect what that thing is because it hasn't been seen yet. However, the System can judge whether the objects inside are valuable or not]

[And about the black vapor, Extreme Dark Qi aims to make this Island float. That being said, this building is the main source of energy that allows the other islands to fly]

"Ah," Lin Xian raised the corners of his lips and became increasingly interested in what the System said.

"Husband, this building looks very dangerous. Shall we go inside?" Fei Ran asked while looking at Lin Xian.
