Ruby's Lake Koss laboratory was situated within a man-made cave, modestly concealed on the outside. Indeed, within the pitch-black underground, it looked quite hidden, significantly difficult to discover.
Ybur crawled toward the entrance of the laboratory and found the stone door at this location with signs of erosion. There were also some dried-up slime trails on the ground, clearly indicating that some slimes had escaped from inside.
"Corroding Beasts don't have the ability to corrode stone; it was caused by another breed of slime," Sherry analyzed. "Our previous guess wasn't wrong; without people here for a while, the slimes indeed have escaped..."
Ybur felt disheartened, "Don't say that... I came here in search of rare Slimes, but after such a long journey, could it be that I've come here for nothing?"
"Not necessarily the worst case. Let's go down and take a look, stay alert, there might be some dangerous beings inside."
Sherry's tone was solemn.
