The ancient battlefield seemed like a small world, but in fact it was vast and boundless. On the desolate land, light sometimes lingered and black mist emerged. Wang Gan walked and found that many dark peaks burst from time to time, and then a vast black mist erupted from it, like ink and water. The air decayed to the extreme, and the space was corroded into darkness, connecting the world of nothingness. He finally understood that the black mist at the beginning was now condensed in the depths of the ground, and sometimes erupted like a volcano. The situation here became more and more confused, and he dared not be careless.
