The Killing Begins, Gradually Changes in Mentality, Dreadful and Monstrous Hiding Inside (2)

In all honesty, why would the Sirens, who live in the deep sea, be bothered by you folks on land who can't even breathe underwater on a regular basis?

As various hero units joined the battle, the sea beasts were horrified to find that they seemed to have a hard time suppressing these thousands of enemy units in this area.

How was this possible!?

They had overwhelming numerical superiority, even if they lost some before, they still had hundreds of thousands of them. Even if it was hundreds of thousands of sea creatures, they should be able to overwhelm the enemy, right?

But those few hero units were just too terrifying, like sharp arrows deeply embedded in their flesh, impossible to remove.

Even when the Tier 5 sea creatures rushed in, the result was the same: instant death.

At this moment, they felt weaker than pigs.
