Boom! Boom! Boom!
One after another, shells loaded with nearly ten kilograms of explosives flew out of the large-caliber gun barrel, fell into the darkness, and exploded with terrifying killing power.
A large number of noble sub-bodies had their limbs exploded, flesh and blood flew everywhere, and they were killed by the shock wave without even being able to scream.
The entire space rumbled and vibrated in the artillery fire, and lime fell from the dome, but there was no cracking or collapse.
Colin felt the ground shaking beneath his feet and looked up at the dome of the ceiling.
[... You realize that this amount of power is not enough to affect this solid underground space. ]
Isn't this inducing me to increase the firepower? That's not good, right? What if it explodes? Colin said with worry in his heart:
"Don't stop, increase your strength!"
At the same time, the last survivor was dragged to a safe place by Shana, so they didn't have to worry about accidental injury.
The next second, crimson erupted again in the darkness, bringing the purest death and panic to these depraved and abominable monsters.
In the smoke of blood and fire, Colin's will was carried out!
At this time, the first row of slaves holding the cannons quickly dragged the cannons back after firing, retreating into the darkness behind Colin.
Then, a new round of large-caliber cannon barrels were carried out from the darkness, and each cannon barrel was carried to the front by two slaves.
Eight in total!
They quickly placed the metallic steel cannon barrel on the temporary solid stone platform.
"Go on. Bomb wherever there's shouting. Bomb until there's silence."
As Colin finished speaking, a fierce light burst out from the dark muzzle and struck into the darkness with a sound of breaking through the air.
Several servants who were holding down the stone platform to stabilize the cannon trembled and were shaken back a bit by the cannon, but they were not seriously injured.
After another round of firing, the slaves, who had become much more skilled, pushed the turrets to complete a new round of rotation more quickly.
The servants who were withdrawn carried the hot and smoking cannon barrel back and handed it over to the busy Li Chou.
Then, he immediately "traded" these cannon barrels to the third-level territory through his friends, and then received new cannon barrels.
When the new barrel was taken out of the parchment roll, it was already filled with explosives. All one had to do was pull the ignition cord to pop out the firing pin to ignite the primer and fire.
The step of loading shells is eliminated, which saves the slaves' learning energy and allows them to get started faster.
As for aiming...
Just go wherever there is a call...
Under the heavy firepower saturation bombing, everything will be purified by artillery fire, and all impurities will be eliminated.
By utilizing the system's functions, the interval between each rotation launch can be compressed to less than ten seconds, and it will become faster and faster as the proficiency increases.
The four survivors stared at the scene in front of them in a daze, with dazed looks on their faces, a little confused about the current situation.
Colin didn't have time to pay attention to them for the time being. He looked around the entire battlefield and used the prompts to observe the entire scene.
He already knew something about these monsters and had also accepted the mission to eliminate them.
At that time, they encountered attacks when they came, but these attacks were easily resolved and dealt with.
Under Colin's guidance and Shana's leadership, most of the sub-bodies posed no threat to them.
