Xu Xin felt somewhat excited.
It must be known that the treehouse core can only upgrade basic resources. This kind of material cut from a creature cannot be obtained through core upgrades; it can only be cut with a boning knife!
A piranha skin lay curled on the ground, emitting a purple glow.
There was only one piece, but Xu Xin was already very satisfied as he reached out to pick up the piranha skin.
[Mutant Piranha Skin (Purple): A type of animal hide, incredibly tough and 100% waterproof, making it an extremely high-grade material!]
Xu Xin had long known that the tough piranha skin was a type of animal hide; he had already obtained more than a dozen blue-grade fish skins.
Purple-grade animal hide, huh...
Animal hide has two uses: one is for crafting leather armor, the other is for crafting backpacks.
Xu Xin immediately decided to craft this piece of animal hide into a purple-grade backpack.
