Humans!

Jacob looked entirely different from three months ago. His body was brawny as he wore a crude coat made from arrow tail jaguar's hide and a pant made with another uncommon animal's hide.

His face was covered with a thick layer of mud and a long, messy beard, while his hair was crudely cut to his shoulder length. His eyes were filled with sharp, murderous intent. He gave the feeling of a vile barbarian who has gone through many cruel battles.

It was in fact the case as well because after his first month of wandering; he stopped using Pig Head to fight those animals and started to brawl with them himself.

One reason for doing this was Pig Head was wilting with each fight, and the other reason was to get accustomed to his rising strength.

After hunting and consuming nine uncommon and 25 common animals, his body has already become 100% compatible with his current heart. He didn't dare to believe he had such a strength, which was nothing but superhuman, and it was only the beginning.
