"Swordfish Beast"
When the monster hit a barrier, it immediately turned around and dived back into the water within just a second, leaving only water splashes and huge ripples on the surface of the lake.
The lake water was clear, but strangely, people could not see the living beings under the water even with the help of the strong sunlight.
The attack of that monster was precise and fast, and even when it failed, it also 'escaped' cleverly, not allowing any of the contestants on the boat to counterattack.
However, the first attack was like a signal. Various monsters and beasts appeared from every direction and started to slam their huge bodies into the boat's barrier!
BANG! BANG! BANG! SPLASH! SPLASH!
Some beasts with higher intelligence even started to throw various elemental attacks to the barrier, not merely using their physical bodies to attack anymore.
For a moment, the whole boat was attacked by all sides.
