This wasn't newly grown flesh; it was a piece of Drama Robe that had burrowed out from the flesh! He... he could even feel the fragment squirming!
He burst out of the bathroom, crazily tore open his backpack, and pulled out the Drama Robe, only to face an even more despairing scene. A part of the robe's back was missing, and now, shockingly, it had been patched up with a piece of human skin, a piece dripping with blood.
The triangular piece of skin was naturally Yang Xiao's own. His skin had been stolen by the Drama Robe, and part of it had replaced his own skin.
This sudden blow was more unbearable than being killed. Unable to tolerate it, in desperation, he pulled out a dagger, returned to the bathroom, faced away from the mirror, clenched his teeth, and started to cut through his flesh little by little, digging out the piece of Drama Robe.
