Global Catastrophe: I Became the World Tree-Chapter 660 - 376 Defense Battle_1

Boom, boom, boom!

Ye Feng had just arrived at the top of the city wall when he saw a 30mm self-propelled cannon crazily unleashing fire at the base of the wall.

Ye Feng was familiar with this newly developed cannon, its rate of fire could reach 1500 rounds per minute, and it was capable of inflicting lethal damage on Fourth Order Mutated Animals or below.

It also featured automatic enemy locking; when multiple units were used together, they could form a fire network through computer coordination for combined combat.

From inception, this weapon was positioned as a mass killer on the battlefield.

Because most of the Mutated Animals were still at the Third Order, it would at least take until the next Spiritual Energy Resurgence for a large-scale breakthrough to Fourth Order.

And this self-propelled cannon could even effectively kill Fourth Order Mutant Animals.

As a result, since its development, it has been treated with great expectations and has been installed on the walls of cities everywhere.

In key locations, like the military fortress to be constructed in Daxinganling, even more were installed.

Unfortunately, in this war, these highly anticipated new weapons failed to live up to their potential.

Ye Feng watched as the self-propelled cannon in front of him furiously poured firepower into a Mutated Centipede in the distance.

Although sparks flew from the hard shell of the opponent, the damage inflicted was minimal.

After twenty seconds of sustained fire, only about a one-meter gash was made in its hard shell—a mere scratch relative to its body, which was tens of meters long.

The Mutated Centipede, still under the barrage from the cannon, reached the base of the wall and attempted to climb up.

However, it did not succeed, as an elite soldier cloaked in Power Armor and standing by the cannon had already noticed it.

At that moment, he lifted the 2.5 meters long, 120mm caliber 2nd Generation Destroyer Hand Cannon.

Boom!

With the roar of the cannon, the centipede’s head was instantly pierced by a huge bullet, and it merely struggled for a moment before becoming motionless.

Even Ye Feng could not help but admire the tremendous power of the Destroyer Hand Cannon.

Let alone the Sixth Order Mutant Insects, even Sixth Order Mutated Animals could potentially be killed with a single shot, unless they possessed particularly strong defenses.

But the hand cannon had its disadvantages.

To start off, the recoil was immense, and it could only be properly wielded while wearing Power Armor. freёwebnoѵel.com

Besides, each shot required reloading manually.

And the shells were quite large—12 centimeters in diameter and 40 centimeters long.

If fighting in the field, forget about reloading, just carrying these shells was problematic.

For defensive battles, it was much better as there were ammunition boxes that could be dragged around; soldiers could simply pull the boxes wherever they needed.

However, the reloading time was still a problem.

Even though these Power Armors were equipped with an automatic loading program, the entire process took at least five seconds.

In other words, the maximum rate of fire for the 2nd Generation Destroyer Hand Cannon was only 12 rounds per minute.

In such a densely packed battlefield, this rate was simply not enough.

Fortunately, the elite soldiers in Power Armor were not primarily targeting the Mutant Insects, but the less numerous Mutated Animals.

At that time, on the battlefield, the main force against the Mutant Insects were ordinary soldiers clad in Exoskeleton Armor.

They were generally armed with the First Generation Destroyer Hand Cannons.

This generation of Destroyer Hand Cannon was less powerful—it fired 70mm caliber armor-piercing rounds, so naturally, the power was not on the same level.

Forget Sixth Order Mutated Animals, even killing Fifth Order Mutated Beings might not be certain.

Of course, when it came to attacking Fifth Order Mutated Beings, if it didn’t kill them, it could surely inflict severe damage.

Thus, for dealing with the less defensively powerful Sixth Order Mutant Insects, the firepower was just about sufficient.

Because even if it didn’t kill them with the first shot, the second shot would almost certainly do the job.

What matters most is that the First Generation Destroyer Hand Cannon is not as unwieldy, appearing more akin to a Single Soldier Rocket Launcher.

Furthermore, with only 70mm ammunition required, the size of the shells is significantly smaller.

On this basis, the research department added a magazine to the First Generation Destroyer Hand Cannon.

Unlike typical magazines, this magazine for the First Generation Destroyer Hand Cannon was very large; calling it a magazine is somewhat misleading, it’s more like a combat backpack.

Although it looked somewhat bizarre, its effectiveness was undeniable, boosting the firing rate from 12 rounds per minute to 60 rounds per minute.

Therefore, the ordinary soldiers wielding First Generation Destroyer Hand Cannons were the main force against the Mutant Insects.

Yet even with the faster firing rate, facing the endless swarms of the Mutated Creature Army, this firepower was still somewhat inadequate.

Every now and then, Mutated Animals broke through the blockade line and came close to the walls.
