I see!

General Val looked at the wire ropes and felt a sudden realization.

Those wire ropes may seem simple, but they can slow down the armored giant cockroach army and even make them kill each other.

The function of the outermost ring of steel wire rope is to prevent the armored giant cockroach from using its jumping ability to cross obstacles, because the height of five meters is enough to block the armored giant cockroach in the air. In fact, many armored giant cockroaches have hit the steel wire rope in the air and fell one after another.

scene.

The second and third steps no longer need to consider the bouncing of the armored giant cockroach. They simply force the armored giant cockroach to crawl under it. Under this situation, the speed of the armored giant cockroach is once again slowed down.

The fourth line of defense of the steel wire rope is multi-functional. The three layers of steel wire rope prevent the armored giant cockroach that breaks through the first three lines of defense from approaching the steel city wall at high speed...

…

Genius design!

Genius design!

Val couldn't help but secretly admire that the refugee leader of Fortress M23 was definitely a genius. He used the simplest materials and the lowest cost to solve problems that humans have been unable to solve.

Since the outbreak of the armored giant cockroach disaster, mankind has not had an effective way to curb the tide of armored giant cockroaches. Even if there is one, it cannot be promoted because the cost is too high.

Iron pillars, steel wire ropes.

There is no doubt that the two materials, iron columns and steel wire ropes, are cheap and easy to promote. As long as you are willing, you can build them in a few hours.

At this time, Val has decided that he will promote this experience on Sunshade Star. He believes that with this defense system, the armored giant cockroaches will lose their speed advantage, and the survival probability of those fortresses will be greatly increased...

…

The armored giant cockroach that has lost its speed has become a target for humans.

The lethality caused by more than a hundred people shooting at the same time is extremely terrifying, because the densely packed armored giant cockroaches do not need to aim at all. Just shoot at will to kill the armored giant cockroaches. Even if they are shot, the armored giant cockroaches will be injured.

The giant cockroach army causes trouble. After all, the injured armored giant cockroach will struggle like crazy, which in turn will cause trouble for similar charges.

One shot can cause casualties to one hundred armored giant cockroaches, and one shot takes about two seconds. In other words, one thousand armored giant cockroaches can be killed in twenty seconds, and ten thousand can be killed in three minutes.

Of course, this is just a literal figure, and the actual kill figures are much smaller. After all, many armored giant cockroaches are only slightly injured.

The steel ropes and the continuous shooting still dampened the unstoppable arrogance of the armored giant cockroach army. They crowded into a ball in the wasteland like snails. After finally getting through the steel wire mesh, they faced intensive firepower.

However, the numerical gap between the two sides is really too big. The number of armored giant cockroaches exceeds 100,000, while the number of refugees is only more than 100, and there are no weapons of mass destruction.

With the absolute advantage of numbers, the armored giant cockroaches still approached the steel city wall. However, they had lost their speed. After losing their speed, it would be a lot more troublesome to use the method of stacking arhats to invade the fortress.

Shooting at close range replaces shooting at long range.

General Val became inexplicably nervous. He had never been nervous about the lives of refugees. In his eyes, these refugees were cowards who abandoned their homes. But now, he hoped that these refugees would survive because they were special.

Now, General Val even regrets not providing more advanced weapons earlier, such as mechas and exoskeleton armors.

It's a pity it's too late!

Although these refugees are brave and good at fighting, General Val still does not think highly of them, because at this moment, under the city wall where the army of armored giant cockroaches is approaching, it is impossible for more than a hundred refugees to defeat a hundred thousand armored giant cockroaches...
