In The Zombie Shadows Chapter 72

The vision Jake Qi encountered in the sea was actually a hunt by native killer whales.

Dolphins and seals join in midway, obtain the consent of the killer whales, swim around the group of whales, and drive the prey into the preset encirclement, ensuring that all targets are caught.

The turtles were just there to join in the fun.

This sea area is his territory. The killer whale opens an energy shield in his territory to round up shrimps and fish. As the owner of the sea area, he naturally wants to declare his presence and catch a few shrimps for tooth sacrifice.

Killer whales have extremely high IQs and equally amazing strength, ranking among the best among native marine species.
