82. Escape the Natural Barrier_3

It was like a long snake lying on the ground, covered with knife blades all over its body.

Not only were the mountains layered and stretching for thousands of kilometers, but there were also numerous towering, blade-like peaks pointing towards the heavens.

"Chief Officer, do you mean that the underground river beneath our feet flows from south to north towards the Blade Mountain Range?" Noland Lee asked thoughtfully.

Sergeant Mars replied while changing his clothes:

"Yes, the flow from south to north is downstream. Moreover, the water volume of that underground river is relatively stable, with a swift flow. If it weren't for the large scale of Undead Cult's fleet, their extremely high load, and slow sailing speed, we would have no chance of stopping them."

Noland Lee nodded thoughtfully and asked:

"What is on the other side of the mountain range? ...Ah, I remember now; it's the Golden Federation, right? It was mentioned in the Academy's classes."
