Klein naturally didn't know that someone had guessed that the cave from before was his handiwork.
But even if they knew, it didn't matter.
After all, as the catacombs continued to be opened up, there were fewer and fewer places to explore, so the chances of encountering them naturally increased.
And on Klein's side.
As he stepped into the teleportation portal.
With a flash of white light, he instantly disappeared from the resource cavern and arrived at a very unfamiliar place.
Klein regained his consciousness and looked around.
The area around him was very large, not much smaller than the catacomb he had faced against the Armored Scorpion and the others.
The difference was that this world was filled with boundless poison gas.
He smelled the poison gas that filled the space.
Klein frowned and thought to himself, 'Looks like the situation is more serious than I imagined.'
