He said after thinking about it. "Let's do it. I need all the strength I can get right now."
If he were a single entity whose entire life depended on this decision, then he would decide against allowing his divine ability to do what it wants. But he is not alone. His death will not be the end of Legion. He can take risks that he would be too cautious to otherwise.
He lay on the ground and stopped impeding the heat in his abdomen. The heat spread throughout his body wantonly. It filled every inch of his body to bursting. His body became full of so much energy and vitality. It is the energy and vitality that he got from his recent meal. Then his divine ability got to work on modifying his body by using that energy and vitality.
"Hmpf." He groaned as the first tear appeared on his small body. "This is going to be painful."
Cracks began to appear on his body as his skin tore. His body cracked due to his divine ability. One needs to tear down something before rebuilding it so his body is being torn down. His muscles tore open and his bones broke. His organs shifted as they enlarged within him. Blood pooled beneath him from all the injuries that he is suffering.
"This had better be worth it." He growled.
His body is going through excruciating pain. It shouldn't be so in a normal situation. In a normal situation, his divine ability should only awaken when he becomes a Mana entity. A Mana entity's body will be more malleable to change so the upgrade will be less painful. But he activated it early and he fed his divine ability too. So his fragile body is being made to go through the pain of an upgrade now.
This pain is something that will kill any other cub. It will also traumatize mana entities with weak will. But he isn't any simple cub. He is special so he must do special things and endure special pains. After all, there is no gain if there is no pain. And there is no special gain without special pain.
The pain will be worth it. He is growing stronger and it is visible. It is all he needs to see to know that he made a good decision to allow his divine ability to get to work on his body.
His little body enlarged quickly. He went from being 10 centimeters in length from neck to rump to increasing to a meter long. Everything about him grew bigger and stronger. His divine ability digested the food he ate and empowered his body with it.
This is the major reason why he decided to indulge his hunger and eat his mother. It is not because of the twisting hunger in his stomach. He is better than that. It is because it will not only alleviate the symptoms of using his divine ability. It will also make him stronger and he will do anything for strength as long as he can do it.
His ancestors were addicted to violence because of the taste of food but he won't be like them. He is not a base creature that can't control himself. That doesn't mean he won't get addicted to violence. But if he does, it will be by his choice and because of his strength. Violence will be a tool to further his goal, not the goal itself.
Strength above all else is supreme. If one is to be the fittest, then one must be the strongest, or one won't survive. He reincarnated to acquire strength and he will pursue it even if he has to doom an entire plane to Oblivion. It will all be worth it as long as he becomes stronger. So what's a little pain? It is nothing compared to what Legion-3 is currently going through and has been going through for years.
The thought of Legion-3 distracted him from the pain of his body. He wondered to himself, "It is probably a mistake to create a demon clone. We had no idea that Chaos is attracted to demons. Where does Chaos energy even come from?"
He allowed himself to think about the conundrum of Chaos energy while his body broke apart and was reformed several times. Finally, he went through the last change. His broken bones fused together and were covered by muscles that reattached themselves and healed. Then all of them were covered by a layer of skin and fur.
The pain ceased then and his body stopped breaking itself. His horns have grown out on his head. They are black, straight, and very pointy. They look quite dashing even though they are small. He stood up and was able to stand on his two hooven feet.
"What a wonderful surprise. I am at the Vitality core stage already." He said in amazement. "That's good. This will make things a whole lot easier."
He examined himself and felt the vitality core within his stomach. His divine ability formed one for him. He skipped the body forging stage and jumped to the vitality core stage immediately.
He expected to strengthen himself to the peak of the body stage. That is more than enough strength to move better. Walking around in an unfamiliar and dangerous environment as a baby will lower his chances of survival drastically.
His current strength surprised him a little but it is also understandable when he thought more about it. The flesh he ate was from someone at the peak of vitality core stage so it is reasonable that he was able to form his own vitality core from eating all of her flesh. It is just strange that it formed in his stomach instead of his heart like normal races.
"Let me unlock my spirit and check the stat screen."
Unlocking the status screen requires an awakened spirit. His new form can withstand the awakening of his spirit so he decided to do it.
