"Fire!"
The sergeant shouted, and the helicopter swiftly flew towards the sky, while the six gun emplacements on the ground had already adjusted their guns, and the soldiers were stuffing cannonballs the size of water buckets into them.
Boom! Boom!…
One after another, the guns fired cannonballs, bursting into flames. Six shells plunged into the lake at a high speed, sinking like stones in the water, causing almost no splash.
Watching this silent scene, Tang Ye felt like laughing. However, soon after, he saw bubbles rising from the lake surface. Just when he was puzzled, the water surface suddenly bulged as if there was a huge bubble beneath.
Seeing this, Tang Ye knew something was wrong!
"Damn!"
Suddenly realizing what these were, he remembered seeing something similar in a documentary - a type of shell known as a thermobaric weapon, also known as a penetration bomb!
