85. Energy explosion again_2

"Heads up, Jarvis, the target ships are coming."

Corporal Mars was holding a chain of bullets, ready to reload for Noland Lee at any time.

He pointed at the fifth boat from the end in the fleet.

The Imperial Army would divide these six ships into three groups.

Their first killer, is the mines buried beneath the river surface.

"Honk~" The leading warship noticed the missing watchtower and sounded a loud horn.

At the same time, Lieutenant Slyke Thompson gestured and gave the order:

"Detonate!"

Upon receiving the order from their superior officer, the soldiers pressed the detonators in front of them without hesitation.

In an instant, several water pillars rising to the ceiling erupted on the long river surface.

"Boom, boom, boom..."

A series of explosions echoed throughout the underground space, creating huge waves on the river surface.
