After passing down the Heaven and Earth Primordial Skill to An Hao, Gu An didn't linger longer and quickly left the island.
In the sky, he saw the distant ocean stirring up massive waves, originating from the place of his breakthrough. The spiritual energy he consumed during his breakthrough was enormous, causing the spiritual energy of heaven and earth to sink, inevitably shaking the ocean.
Fortunately, that sea region did not have any human-occupied mainland. The demon creatures surviving there all had cultivation levels, so even if the island was flooded, they wouldn't die. Besides, the waves just swept across rather than raising the sea level.
Gu An just glanced at it and did not give it much thought, avoiding any burden on himself.
He harbored good intentions and avoided harming innocent beings as much as possible. Still, if his cultivation inadvertently affected innocent lives, he couldn't help it, and he would not stop his progress.
