The Survivors
After almost an hour since the 4 mystic warriors entered the cave, one of them finally came out. Rex, now back in his humanoid state was the only mystic warrior out of the 4 who came out of the cave alive.
On both his shoulders were 2 corpses, Goro and Pain while tied to his waist was a sack that held a round-shaped object from which blood dripped.
Rex came out of the cave with his 2 friend's corpses and the enemy's head.
After he finally succeeded in killing Pain, though his system already gave him a vague explanation about the system rewards that followed, Rex was still astonished by everything that he got after the kill.
He did not only get a bunch of skill points, free stat points, constitution points and others, what fascinated him most was the random ability draw chance.
