After passing the Heaven and Earth Primordial Skill to An Hao, Gu An did not linger and quickly left the island.
From the sky, he saw the distant ocean stirring up huge waves, coming from where he had his breakthrough. The spiritual energy he had devoured during his breakthrough was so vast that when nature's spiritual energy descended, it inevitably shook the ocean.
Fortunately, there were no Human Race continents inhabited by people in that stretch of sea, and any demons that could survive there had their own cultivation levels. Even if the islands were flooded, they wouldn't necessarily die, and the waves were merely sweeping past, not rising sea levels.
Gu An merely glanced at it and didn't dwell on it to avoid burdening himself.
He was kind-hearted and would avoid harming innocent creatures as much as possible, but if innocent creatures were affected by his cultivation in an unavoidable situation, there was nothing he could do about it. He would not stop his progress.
