Noah took down the hard, rocky terrain of the underground area with his bare hands.
June followed closely behind him, she wielded her spear tightly in her hands, ready to stab anything unusual that came out during their advance.
Of course, Noah had told her not to intervene unless the situation became really dangerous.
He didn't want the two of them to release "Breath" in that unknown area, which would only reveal their position to any being inhabiting the underground.
Also, he could take care of any beast and plant below the fifth rank with his body alone, he was a hybrid in the upper tier of the fourth rank after all.
June agreed to his terms, but she still preferred to have her weapons next to her.
Noah used his consciousness to keep track of his direction.
Their advance was slow, and they had to take breaks every few weeks, but they didn't meet anything out of the ordinary in the first part of their travel.
