The whole book, the latest chapter of the origin of the genetic war is updated as soon as possible!

Seeing that the projectile insect was so careful, Zuo Gangchen smiled knowingly, the distance of four kilometers is not far and not too close, this is the illusion that Zuo Gangchen created for the Zerg, under normal circumstances, the projectile insect will hide behind the Zerg, and when the Zerg launches a large-scale attack, secretly launch a few meat ball bombs.

But now the Zerg not only has no quantitative advantage, but also loses the quality advantage, if the projectile insect hides far away, the meat ball fired may not even touch the edge of the battlefield, and it will be killed by the electromagnetic gun.

If it were Zuo Gangchen who controlled the Zerg, I am afraid that he would have been hiding in Weinan City and would not be able to hold out, engage in street battles with the other party, and wait for rescue.

In fact, this is the thinking of human beings themselves, but the Zerg are different, a bug has an extremely fast growth period, and even if it becomes a high-level bug, the speed is far beyond the cultivation of humans, just like a chicken farm eating hormones, and there are still a batch of dead ones.

Thousands of Rippers formed the backbone of the attack, and instead of rushing to attack the army commanded by Zuo Gangchen, they sent two teams of 100 bugs to advance tentatively from the left and right directions.

Zuo Gangchen, who discovered this situation, immediately asked the other ten miniature electromagnetic cannons to kill them with fixed clicks, otherwise the insects would approach his left and right wings.

After losing dozens of bugs, the Zerg decisively gave up the temptation, and let the projectile insects in the rear carry out a round of projectiles, and more than a dozen explosive meat balls flew over Zuo Gangchen's position, only to be shot down one by one by the soldiers who were waiting for them in mid-air.

After a few small-scale tentations, the Zerg seemed to know Zuo Gangchen's deployment, and after making some adjustments, a heart-stopping roar came out from the swarm, and thousands of Rippers stepped on the ground and began to run.

The Ripper is extremely fast, running at high speed at a speed comparable to a sports car, and at full speed, the distance between the two sides is four kilometers, and the Ripper does not need a minute.

The purpose of the Zerg has been exhausted, and they want to use the Ripper as a precursor to tear Zuo Gangchen's defensive formation, and there are dozens of high-level bugs hidden among the thousands of Rippers, and their combat power will be exerted to the fullest in close combat, staging a bloody slaughter.

Zuo Gangchen had long known that there were high-level bugs hidden among the Rippers, but it was impossible to distinguish those hidden threats in the high-speed movement.

Bugs of the same breed, the larger the size, the stronger the strength, for example, the most common ripper in the Zerg, the body size at the first level is larger than a car, and after the strength rises to the intermediate level, the body size is the size of two cars, so as long as you see those slightly larger bugs in the insect swarm, the general strength is not too weak.

"Electromagnetic rapid-fire car ready!"

The electromagnetic rapid-fire vehicle is the only weapon of mass destruction in Zuo Gangchen's hands, a salvo is equivalent to three hundred electromagnetic rifles firing at the same time, which can cover an area of more than 30 square to 300 square meters in the front at one time, and its lethality is lower than that of electromagnetic rifles, but higher than that of electromagnetic pistols, and it has unparalleled terrifying lethality against a large number of low-level bugs, or a small number of medium-grade bugs.

The advantage of the electromagnetic rapid-fire vehicle is that it covers a large area and has an extremely fast launch speed, which can launch 300,000 mass bombs in the vehicle within one minute, forming a storm of mass bombs.

Of course, there are many disadvantages of electromagnetic rapid-fire vehicles, first of all, the power is not strong enough to pose a threat to high-level insects, and secondly, it needs to consume a large number of mass bullets, which is equivalent to consuming more than 10,000 points at once, and finally the killing range of electromagnetic rapid-fire vehicles is less than one kilometer, which is almost a one-time attack weapon for electromagnetic rapid-fire vehicles that need to be reloaded for up to half an hour.

And the cost of the electromagnetic rapid-fire car is not cheap, just by looking at the consumption of ammunition, you can know that this is a gold-swallowing monster, even if you don't need Zuo Gangchen to spend money, it also makes Zuo Gangchen's flesh hurt.

The three electromagnetic rapid-fire vehicles quickly adjusted their orientation and began to lock on to the direction of the Zerg's attack.

The first to attack is not an electromagnetic rapid-fire vehicle, nor a soldier on standby, nor a miniature electromagnetic cannon that is always looking for the best target, but a sniper hiding everywhere.

Like the sniper rifle in human weapons, there are also sniper rifles in electromagnetic weapons, and the power of electromagnetic sniper rifles is not as great as that of miniature electromagnetic guns, but it is more flexible, and the quality of soldiers is also higher, and at least it requires an awakened person with relevant abilities to use.

Among the awakened in the past two days, Zuo Gangchen only selected sixteen awakened people with relevant abilities and equipped them with more advanced electromagnetic sniper rifles.

The distance of the electromagnetic sniper rifle is not to look at the shooting distance of the gun itself, but to see the strength of the target to be killed, the stronger the target strength, the shorter the sniper distance, otherwise the success rate of the kill cannot be guaranteed.

"Bang bang bang!"

As soon as the Zerg launched an attack, there were sniper guns one after another, and Zuo Gangchen didn't even look at it, and he knew that those snipers just missed the target eight times out of ten, although the types of sniper rifles used were different, but the training of snipers was the same at all times.

The selection of snipers is very strict at all times, in addition to the talent of shooting, it is necessary to have good military literacy and strong endurance.

It takes a long time to train a sniper, and it used to take at least two years to train a sniper, and the same sniper rifle was also the most expensive of the firearms of the era, so some people say that training a top sniper is similar to training a pilot, and this sentence is not wrong at all.

Cultivating an electromagnetic sniper is more difficult than training an ordinary sniper, first of all, you must have the quality of an ordinary sniper, and secondly, you must have the talent of awakening.

The reason why the electromagnetic sniper will be more difficult, of course, is that the target of the sniper has changed, you must know that the electromagnetic sniper is not an ordinary person, but a high-level creature, many high-level creatures will have a sense of crisis when they are locked by the sniper, at this time, if you want to snipe high-level creatures, the difficulty increase is not several times, but dozens of times more.

Zuo Gangchen didn't expect to be able to train higher-level snipers in a short period of time, but just wanted to let the selected snipers grow up quickly in actual combat through actual combat.

As the electromagnetic sniper rifles sounded one after another, the battle between the two sides officially began, at this moment Zuo Gangchen was no longer nervous, only the unknown would make people uneasy, since the Zerg chose to attack first, the Zerg's combat intentions were also understood.

"Order the seventh, eighth, and ninth artillery companies, look for high-level bugs to shoot!"

"Order the electromagnetic rapid-fire vehicle to attack after the Zerg front enters a one-kilometer range!"

“……”

Orders came out of Zuo Gangchen's mouth, but Zuo Gangchen's eyes did not look at the direction of the Zerg's attack, but turned his head to look at the rear of the Zerg, which was the direction where Lu Tianyu was hiding, and now both humans and the Zerg have long-range reconnaissance capabilities, and any action on his side could not escape the surveillance of the Zerg, which was very unfavorable to Zuo Gangchen's defense.

More and more projectile insects threw meat balls and flew over the battlefield, although many explosive meat balls were shot down by soldiers, but there were also a few explosive meat balls that broke through the fire net and landed on the human position.

The exploding ball of flesh splashed countless corrosive liquids and landed on the soldiers who were shooting, emitting pungent pungent white smoke and emitting a corrosive snort.

This made many soldiers very panicked, and hurriedly went to check the armor on their bodies, but found that the corrosive liquid had little effect on the armor on their bodies, and they only needed to spray it with the pre-prepared neutralizing liquid to neutralize it, leaving a dazzling mark on the armor on their bodies at most.

However, this still makes many soldiers afraid, if it weren't for the nano armor on their bodies that can slow down the speed of corrosion, and the neutralizing agent to eliminate corrosion, those soldiers who are hit by the corrosive liquid will not need dozens of seconds, and there will be no bones left.

But even so, there were still a few soldiers who were accidentally hit head-on by a large amount of corrosive liquid, and they didn't have time to use the neutralizing potion at all, so they collapsed to the ground in a terrible scream, struggled a few times, and disappeared from the eyes of the other soldiers, and even the nano armor on their bodies was not left.

Seeing this situation, the soldiers hiding in the foxhole raised their understanding of the Zerg to a new level, and they didn't expect that the corrosive liquid of the Zerg could actually corrode the armor made of nanomaterials, is there anything else in this world that can't be corroded by this liquid?

Of course!

Or the most ordinary thing, that is, the dirt that can be seen everywhere.

Some soldiers found that those corrosive liquids didn't seem to have any effect on the surrounding soil, and an officer who had just awakened the earth-based ability, after discovering this, immediately raised a dirt wall in front of the surrounding foxholes to block it, as long as it was not directly hit by those explosive meat balls, it would be blocked by the wall in front of them, and those corrosive liquids could not hurt the surrounding soldiers at all.

At this time, many soldiers remembered that before the battle of the previous two days, there were hundreds of combat experiences that every soldier had to keep in mind.

For example, this kind of foxhole is the key point that must be prepared before the station, because there has been no positional battle with the Zerg in front, so many soldiers have not felt it, and now it is found that ordinary trenches and Zerg are not as practical as the foxhole.

Another example is that when soldiers go to battle, their armor must be neatly worn, even their eyes must be protected with goggles, and an extra layer of nano underwear must be worn under the armor.

Another example is to require the soldiers of each squad to dig another hiding hole in the foxhole, and it is best to have water ...... in the foxhole.

There are hundreds of experiences, and even for veterans, these experiences are a bit too much, and they can't be remembered at all, let alone used all of them before the war.

Feeling the vibration from the earth, Zuo Gangchen stared at the route of the Zerg's attack, in the open space between the two sides, he had laid a two-kilometer-wide mine belt, and tens of thousands of high-explosive mines were hidden underground, as long as the insects stepped on it, they would be detonated.

The low-grade bugs rushed to the front and detonated one mine after another, and after the death of two or three hundred low-grade bugs, the mine belt with a depth of one kilometer was torn open a passage about 100 meters wide.

However, Zuo Gangchen didn't expect the mine belt to hinder the Zerg's attack at all, he just hoped that the mine belt could slow down the Zerg's attack, so that the snipers and miniature electromagnetic cannons could lock on to those high-level bugs.

Judging from the videos of the previous battles between the human army and the Zerg, the main reason why the human army is defeated is that the Zerg broke into the human army formation.

Often when the high-level bugs of the Zerg rush into the human army, they are basically defeated.

Because there are very few weapons and monks in the human army that can kill high-level insects, when soldiers are attacked by high-level insects, the bullets fired in the panic will often accidentally injure the surrounding comrades.

At this time, there was a situation on the battlefield where the human army was chased away by the Zerg, and the army behind did not dare to shoot, for fear of accidentally injuring their comrades, even if the officer ordered the attack, the soldiers killed would definitely be too many more than the bugs.

The reason for the defeat of almost every human army is similar, so Zuo Gangchen is very clear about the purpose of the Zerg tactics.

At the expense of low-level bugs, cover the high-level bugs behind to break into the human army's position, completely break up the human army's establishment, and finally chase the soldiers all the way.

Humans have also discovered such tactics as the Zerg, but they can't find a strategy to deal with them, so they can only watch the Zerg break into the position and slaughter the human soldiers.

However, Zuo Gangchen has already prevented this situation, and now is the time to test this tactic.

It is almost impossible to block the Zerg in front of the formation, unless Zuo Gangchen now has more than five times more heavy weapons in his hand, it is possible to suppress thousands of Zerg to fight, or if the army has cultivated a large number of middle and high-level monks, in order to confront the Zerg head-on in the case of equal numbers.

A hand-to-hand fight is simply unavoidable, and what Zuo Gangchen needs to do is to minimize this casualty.

But when the Zerg rushed to two kilometers, five or six thousand electromagnetic rifles began to strafe, and with the shooting of electromagnetic rapid-fire vehicles and miniature electromagnetic cannons, more and more bugs fell on the offensive route.

However, this can't stop the pace of the Zerg's attack at all, with the death of a large number of low-level bugs, the mid-level bugs behind have become the main force of the attack, and the defense of these medium-level bugs is no longer something that one or two electromagnetic rifle quality bullets can kill.

The medium-level bugs were carrying countless electromagnetic mass bullets, and after dropping hundreds of bug corpses, they finally rushed to the front of the formation, but at this time there were not many bugs left.

Seeing that less than two or three hundred insects broke into the position, Zuo Gangchen glanced at the rear of the Zerg again, and at this time, three dull sonic booms sounded behind the Zerg, Zuo Gangchen couldn't help but look towards the wanderers floating above the rear of the Zerg, and saw that there were three wanderers with a big hole in their bodies, and the countless long tentacles hanging on the loiterers waved wildly, and the four pterosaur beasts hiding behind also turned around and flew in the direction of the sonic boom.
