The Burrowing Rat may be a Tier 4 Mutated Beast, but it's not an aggressive one in the world of Apocalypse Rogue. In the eyes of many martial artists, the Burrowing Rat represents a golden opportunity.

Even without considering if the Burrowing Rat has a Star Crystal, just its pelt alone is worth a low-grade blue crystal. Its meat is incredibly delicious and is a sought-after delicacy among the upper class in Titan City. When prepared by a renowned chef, its price can rival that of a low-grade blue crystal.

However, Burrowing Rats are not abundant, and Zhou Zheng didn't expect to encounter one here.

More importantly, the Burrowing Rat's pelt is incredibly smooth and elastic, making it difficult to obtain a complete one.
