Since more than 3 days ago when Sebastian embarked on his migration journey with the Great White Sharks of the Firelight Shark Clan, for some reason, Sebastian's danger senses kept on tingling which was weird.
Originally, in normal circumstances, he would have paid more attention to this since experience already taught him to trust his intuition.
The reason why he didn't pay too much attention to it was because of the Orca Revolution. Due to the Orca Revolution, literally, every part of the Green Mist Sea was now a hazardous zone, nowhere was safe.
Migrating with such a large group of Great White Sharks, it was bound that they would encounter dangers as they migrated which was normal.
This was the main reason why Sebastian didn't pay extra attention to his intuition warning, but now, he knew the real reason why his danger sense tingled.
