บท 492: Sealed Off

Kieran quickly went up to the deck and saw three iron battleships lined up further away. The flash of their cannons was shining brightly.

BOOM BOOM BOOM!

The relentless firing was ceaseless.

Some of the iron pellet missed and landed in the sea but some struck precisely on The Coral's force field barrier.

Layers of ripples spread out on the invisible barrier when the iron pellet hit it, even The Coral was shaken a bit but not as fierce as the first strike, maybe not even a tenth of the first.

Kieran subconsciously looked into the sea. He faintly spotted some round floating objects deep under the area and he frowned.

"Water mines!"

Even though [Explosive Weapons, Explosives]'s knowledge didn't include water mines, it didn't stop him from knowing what water mines could do. They were cheap, had formidable explosive force, easy to deploy but hard to disengaged.

Kieran didn't just spotted the water mines, he also realized the meaning behind it.
