Chapter 673: Holy Polaris Region (2)

The secret tunnel was extremely long, not to mention it was only ten-meter-long in diameter, which was quite stiff for Jacob's size, but since it was underwater, he could easily swim through it.

When he reached the end of the tunnel, it opened up in another building within the Holy Polaris Region.

But Jacob exited the tunnel when he heard a static voice, "So long, you damn fishes, I had enough of you all!"

He saw a cloaked figure no far away holding a shimmering runic plate in his hand. The other party also noticed the faint ripples in the water behind him, and he quickly turned around!

Both Jacob and the cloaked figure were astounded and bewildered when they saw each other, especially Jacob, who noticed the oxygen mask probing out from the cloaked figure's head.

'He's from the surface!' Jacob instantly thought and quickly reacted by activating the slumber hex.
