He realized that he wouldn't beat it if he didn't use all of the advantages he had, as he thought of this a large pair of wings unfolded on his back shredding the flesh that was in their way. The wings were large and black, with a large curled claw attached at the top, like the wings that wyverns have instead of the ones that most would think that dragons would have. Along with the wings a large set of black and sharp claws grew from his usual sharp nails.
With one flap of the 4 meter long black wings, he was already several feet off the ground, as he kept flapping his speed and altitude increased until he was directly over the wolf. As soon as he was over it, he dived, turning into a spinning humanoid creature with its claws stretched out ready to attack anywhere in the 360° radius around him. Without even realizing that John was above it, the creature died as he pierced it with his claws instantly shredding its internal organs with the insane speed he achieved in his nose dive.
As soon as he landed, he folded his wings which retreated back into the holes in his back the muscles stitched themselves back together over the holes with a layer of skin soon following and then he retracted his claws back into his fingers blood dropped from the fingers, his body apparently hadn't accepted the fact that he could change his form. After standing on his feet and raising his head in victory for several minutes he then collapsed tiredly on the floor and soon after the abyss cage also collapsed returning as a wave of energy into his body slightly refilling his dantian with its power.
After an hour of resting in the nice grass he finally was refreshed from his immense usage of his physical power and energy. He felt refreshed and stood there breathing deeply for a bit but, he soon after he went to where the corpse laid in the grass blood scattered for over three feet in each direction. When he reached where the skin and blood was, he noticed that the normal red orb was larger and there was also a green orb with a flowing substance that looked as if it held immense power with-in. He didn't think much of it, as he would find out more about it later when he was out of the dungeon.
He began roaming throughout the plain, but due to the wolf blood covering him and the fearsome show of might he had just displayed the monsters kept their distance. This forced John to travel deeper into the territory, he continued into the depths passing many miles and after several hours he found a river. He quickly bathed and rinsed all the blood off and began looking for an opponent at his level. After hiding and sneaking his way through the forest near the river for several more hours he had finally made his way out of the depths and arrived at a plain again.
The rest of his time in the dungeon was much more calm, he managed to get 5 more cores sadly he was crushed to death by some random passing monster, which was several levels ahead of it because he didn't even sense it as he exploded from the sheer mass and power of the beast.
He awoke with a violent gasp and he sat up really fast, his whole body hurt after he had been crushed to pulp. He decided to ignore the pain and use the orbs. After about an hour and a half he decided to stop right before he ate the larger orb, because he saw a message: ' skin fully tempered, starting to temper your organs and blood: 17.5/200%'.
He then decided to absorb the larger orb and as soon as he did that, he felt overwhelmed by the energy coursing through his body, via his veins. Flowing through with an immense force his veins began to hurt from the power of the energy.
