Cain did not stop, continuing to flash ahead at an overwhelming speed while the Wind Tribulation followed him. Although the Law of Space and the Void Weaver Art allowed his body to achieve an overwhelming speed, Cain knew he could not escape the sky. However, that was not a problem, as his goal was not to run from the Tribulation.
Cain only wanted to reach a desolate place where there would not be collateral damage. After thirty seconds, he stopped running as he had reached an empty poisonous swamp, void of any sentient life form.
Less than a second after Cain's stop, the sky turned dark, and the power of the Wind Tribulation flooded the place with even greater strength than before, seemingly enraged by the fact it had to chase him.
