One Thousand Seven Hundred and Ten Three-Dimensional Attack

Ye Han knew very well that the insects themselves had no intelligence, at most they had some instincts. With such a large scale of insect swarm, it was absolutely impossible to complete such a complex attack by instinct alone.

In other words, there must be insect people hiding in the dark to command the insect swarm. If the insect people in charge of command can be found and killed, the insect swarm will lose command and may even fall into chaos.

But compared with the insects, the insect people are too inconspicuous. They can hide tightly wherever they go. It is unrealistic to find the insect people.

The pace of the insect swarm is getting faster and faster, and the heavy light insects are also moving forward step by step with the charge of the insect swarm. The heavy light insects are tall and heavy, and the insect legs are thick and long. They seem to move slowly, but in fact they are not much slower than the running giant insects.

Not long after, the insect swarm rushed into the battlefield full of charred insect corpses. A little over a kilometer away is the fortress building at the edge of Funing.

At this time, the insect swarm suddenly exerted its strength and its speed suddenly increased.

The heavy light bugs following behind were just the opposite. They stopped two kilometers away, aimed the launcher on their backs at Funing, and suddenly shot out a series of thin lights.

The thin lights fell accurately on the fortress building, over and over again, and again... Ye Han's eyes twitched. This is the rhythm of demolishing a building!

If the Zerg swarm charging in front is infantry, then the heavy light bugs sweeping in the back are artillery. The tactics of the Zerg swarm are the obvious coordination of infantry and artillery.

If the heavy light bugs bombarded him for a while before the Zerg swarm charged, it would be equivalent to the artillery preparation before the charge.

Ye Han couldn't help but sigh. The tactics of the Zerg swarm are really as many humans as there are humans. If they threw a wave of incendiary bombs at this time, none of these bugs could escape and all had to go back to their grandma's house.

Such an obvious opportunity, even if Funing didn't find it, the other troops responsible for support should not miss it. What was the reason for not seizing this opportunity?

The "bombardment" of the heavy light bugs was very effective. The outermost fortress buildings were scarred by the continuous cutting of the fine light. Before the insect swarm rushed to the front, two fortress buildings had collapsed.

All the humans who saw this scene felt heavy in their hearts. Although everyone knew that the number of times the fine light could be fired was limited, such a solid fortress building was destroyed by the heavy light bugs. Can the fortress buildings stop the bugs?

At this time, the large-caliber mortars of the defenders also sounded. The longest range of this thing exceeded eight kilometers. The distance between the heavy light bugs and Funing was only a little over two kilometers. The heavy light bugs could be eliminated with artillery fire.

The scene not long ago reappeared on the battlefield.

The mortars and heavy light bugs fought across the battlefield, but the mortars were indirect firepower, all set up on a safe rooftop; while the heavy light bugs were direct firepower, no matter how intensive the counterattack was, they could only hit the fortress building.

On one side, the artillery fire was covering the area at all costs, while on the other side, the artillery fire was desperate but could not hit anything. The situation was extremely unfavorable to the heavy light bugs. After a while, the artillery group killed dozens of heavy light bugs.

However, the mortar is not a guided weapon after all. Whether it hits or not depends not only on aiming, but also on luck. It is rare for a single shot to hit. In most cases, several mortars fired at the same time to increase the hit rate by increasing the number.

As a result, the sound of the artillery did not last long, and the shells were hit, so the artillery fire had to be stopped.

This wave of artillery fire was aimed at the heavy light bugs, and none of them fell into the flying insect swarm. When the artillery fire ended, the insect swarm also rushed to the edge of the city.

According to the military's plan, the insect swarm should rush directly into the short street between the fortress buildings, and then be hit head-on by the defenders, and have to retreat after suffering heavy casualties.

But what is the reality?

The swarm of insects did not rush into the short street at all, but quickly climbed up the empty fortress building and climbed up step by step along the wall. Only a few giant insects facing the short street rushed in directly.

Originally, the muzzles of the guns on the defense line were guarding against the short street. After discovering the abnormal attack route of the swarm of insects, the command center immediately adjusted the deployment and sent more people to the rooftop to prevent the swarm of insects from breaking through the rooftop.

The straight-line distance between the rooftops is more than ten meters. For most giant insects, this distance is no different from a natural moat, but for springtails, more than ten meters is really not a big deal. They can jump over it at any time.

Faced with all this, all the defenders, including the special service team, were on high alert and ready to open fire at any time.

There was a dense sound of gunfire downstairs. It was the machine guns in the firing point that were firing. Countless bullets were like invisible flame whips, hitting the giant insects rushing into the short street from all directions and angles.

As soon as the insects rushed into the short street, they were hit head-on by a hail of bullets. One second they were running fast with their legs spread out, and the next second they fell headfirst and rolled on the ground. It was like there was an invisible wall on the short street, and no one could break through the blockade of the defenders' firepower.

However, the swarm of insects did not rush blindly. They quickly changed their tactics. Some giant insects continued to attack the short street to attract the defenders' firepower, while other giant insects quickly climbed up the outer wall of the fortress building and rushed to the second line of defense on the wall.

Ye Han had never thought of this situation, but the distribution of the defenders' firepower points was very scientific. The firepower originally concentrated in the direction of the short street immediately dispersed, and launched a crazy sweep of the insects in all directions without dead angles.

Looking down from the rooftop, the gap between any two fortress buildings was full of flying bullets. The bullet beams fired by each machine gun were like a continuously extending bullet chain. Many bullet chains combined together formed an invisible and deadly net.

Due to the angle, bullets rarely get stuck in the wall after hitting it. In most cases, they become ricochets. Many bullets fail to hit the bugs, but instead become bullets that hit the bugs.

Of course, the ricochet is not powerful enough to penetrate the bugs' shells. The real fatal threat is the direct hit of the bullets!

The interception firepower is always aimed at the bugs rushing in the front. Often, several or even dozens of machine guns fire at a giant bug at the same time. After a series of bullets, dozens of irregular bullet holes immediately appear on the bugs. Some bullets penetrate the bugs, bringing countless splashes of blood.

However, not all bullets can penetrate the bugs, so the blood is far less than the holes.

Seeing this scene, Ye Han quietly breathed a sigh of relief. He really didn't know that the firepower of the defenders was so strong. Only rifles and machine guns were used to block the attack of the swarm of bugs... There is definitely no shortage of heavy weapons on the defense line, but good steel must be used on the blade. Bugs that can be solved with rifles and machine guns do not need to expose the firepower points where heavy weapons are deployed.

According to the current attack strength of the bugs, they can't even get close to the defense line in a short time. Apart from mortars, other heavy firepower will not be useful for a while.
