Bullet Fish

First seen in Day 189.

Rou encounters 47 of them in the Labyrinth City Aquarium's 【Age of the Gods Dungeon】 made by the 【Demigod of Spring Water】.

A pyramid shaped head as heavy as lead and around 60 centimeters in length, that swim in the air as if it’s like in the water, and when discovering a prey, rush at them at 130 kilometers per hour.

The dungeon strengthened the monsters by 2 levels, making them very tough.
