Illusion?
Upon careful sensing, it's not.
The bone really did break! It was the right leg bone.
Creak!
Another crisp sound.
Casio lets out a muffled grunt, a bead of sweat drips from his forehead.
This time it's the left leg, the leg bone is cracked.
Then, like it was prearranged.
Cracking sounds started erupting from his bones all over his body.
The cracks spread like a spider web across his skeleton, from his leg bone up to his arm, an endless surge of severe pain spreading in an instant.
Casio's heavy breath was becoming heavier, under the onslaught of extreme pain his heart pounded like a drum. The only sound within the secluded secret room was his heavy panting, like a water buffalo. Bone Eating Water was painful, but Casio could still endure.
This was thanks to the continuous stimulation of the training potions.
Which made his tolerance to pain formidable.
