Gu Shi Yi sensed something was amiss, so she dived into the sea again, swimming a mile or two before emerging, only then realizing that the sea behind her was completely enveloped in fog, hazy and mysterious, exuding an odd aura.
It was a critical moment, and Gu Shi Yi didn't want to stir up trouble. After swimming away, she carried the sea serpent demon's corpse and flew into the sky. Only then did she realize that the sea ahead was shrouded in fog, with dense Yin energy, while behind her was bright sunlight and gentle sea breezes. The transition between the two was distinct and clear.
