The origin of the diamond bone orchid
Back at Aster's shelter, things were pretty different, Camila mixed some of the yang crystals which they found at the cave earlier, into the metal walls so that the beasts wouldn't notice them and since they were hidden underground the undead won't bother them too.
While the girls were sharing the bathroom, Aster threw himself on the bed, using the giant version of the armor requires him to use a lot of physical energy, and he also used spirit energy since he injected annihilation into it.
Not to mention the battle of soul energy and murderous aura he had with the evil spirit, in a sense he used powers of the three paths in the fight earlier, so it was normal for Aster to feel tired.
While Aster laying down on the bed resting, the door of the portable bath opened and the girls who looked refreshed and relaxed came out of it, they were wearing casual clothes and were chatting with each other.
