The dark shadow was none other than the Blood Steel Rat, another evolutionary path of the Burrowing Rat.
After devouring the flesh of its kind and gnawing on enough metal material, the Burrowing Rat finally completed its final evolution.
Its defense was comparable to that of the Steel Burrowing Rat, but its aggression was higher.
Two Tier Two Exotic Beasts fighting against the Thousand-Change Silkworm put considerable pressure on the silkworm.
Especially since the claws of the Bloodstorm Rat could secrete highly poisonous venom. If hit by its claws, one would fall into a state of poisoning.
Facing the menacing two Tier Two Exotic Beasts, Ye Bai was nonetheless confident in the Thousand-Change Silkworm.
After all, its defense was extremely strong. Even the Tier Three Sunflower King needed to use seven or eight Vine Whips to defeat it.
