The experience of being focused mainly on training had opened Adam's mind massively and he was becoming more and more adept in the use of the Hunter's mind.
Although it was integrated into his mind, he had control of whether it would influence his mind or not and it was as though there was a scale within his mind that had his desires, emotions and normal self on one side, with the Hunter's mind on the other.
Adam being more careful and using his summons efficiently, hunted the lizard beasts and had bought a low ranked spear from the system in order to deal with them.
It would allow him to deal with them with ease, while keeping his distance from them so that they wouldn't be able to poison him.
