Chaos, boundless.
At the beginning, Su Nan could still see the vast stars, but as he kept ascending, those stars began to resemble mere specks of light dotted on a curtain, gradually moving away from him.
After passing through that layer of "curtain", it was as if he had entered another world.
Here, there was no light, no darkness, only endless gray. A sense of direction was useless here, and if not for the call that guided him like a lighthouse, Su Nan would have been instantly lost.
At the same time, this place was devoid of any Power of Heaven and Earth; here, the consumption of any bit of strength was a loss of that strength.
Once strength was exhausted, one would remain in the Chaos forever, which is why even Emperor-level and Saint-Level wouldn't dare to set foot here lightly.
