Stone-Eating Rats

The four of them had been digging for a whole day. Although they had dug up some concentrated iron ores, they did not see any more valuable ones. They were a little discouraged. Concentrated iron ore was already easily found outside so it was not worth wasting time on this.

Yun Chujiu threw the pickaxe on the ground. "Senior brother Feng Ming, is there no way to quickly determine whether there is anything more valuable?"

Feng Ming wiped the sweat from his forehead. "Unless there is a stone-eating rat. However, stone-eating rats are ancient demonic beasts. It is said to be extinct. It feeds on all kinds of ores and can determine the type of ores in a mine by its sense of smell."

Yun Chujiu's eyes lit up. "This stone-eating rat sounds like a helpful thing! This is an ancient mine. There might really be stone-eating rats alive here! It would be great if we could catch eight or ten of them!"
