"Pei…what is this horrendous mess?" Jin asked as he reached the location that had been pinged by her and the System. The moment he reached the derelict building's entrance, he found Pei sitting there in her fox form licking her bloodied fur. Yet that was not her blood that stained her fur and rather, it's from the Demon Rats with parts of their bodies had been scattered around the scene.
A massacre.
Pei was so bored that she even turned into her fox form which was supposed to restrict her powers significantly to kill the said Demon Rats. And those Demon Rats that were lying on the ground were identified by the System to be stronger than the usual ones.
Their power levels were comparable to Demon Rat Warriors that had been spawned from Cinderclaw's belly according to the System and they were taken down easily even with Pei in a restricted form.
