"Those Beast-eating Fish have formidable teeth; they gnawed a hole right through our city walls. That's the hole they used to sneak in."
Having said this, he looked towards Shi Jie, "I came here to trade with the Dashi Tribe for some of the stones you use for making hard stone tools. We want to block off the side near the river entirely with these hard stones, to prevent these strange fish from entering."
Shi Jie felt a pang of concern, "We don't have many of those stones left in our tribe either. Otherwise, why would we only bring a few stone tools to the annual tribal festival?"
Ge Xing chuckled, "Don't worry Chief Shi Jie, we don't want your large stones for making tools. We just need smaller stones. Large stones leave too many gaps when piled, and while the larger fish can't get through, the small ones can easily slip in."
