For human beings, it will take at least ten years for a person to go to the battlefield from birth to the time when he can go to the battlefield, and the materials consumed are countless.

However, for the Zerg, it is totally unnecessary. After the mother worm lays eggs, most of the eggs can enter the hatching stage after a series of modulation. After hatching, the larvae will enter into various insect chambers with different functions for subsequent gene modification and colonization.

Waiting for a series of modulation, transformation and colonization completed, a qualified insect soldier appeared in the world.

In this series of processes, it takes less than a year for an insect soldier to go to the battlefield from birth.

Compared with the human race, it is more than ten times shorter than that of human beings. The Zerg also took advantage of this huge arms advantage and almost did not bring down the economy and population of the whole Terran in the early stage of the war.

However, the disadvantages of the Zerg are also obvious. These "soldiers" produced in mass production have no other uses except for their amazing fighting power and strong vitality. They even have no self thinking. They are simply cannon fodder born for the sake of war.

Once in the "peace" period, these cannon fodder insects are the biggest drag on the whole Zerg society. Therefore, in order to consume the cannon fodder, the Zerg are quite aggressive.

Before meeting the Terrans, the fierce and fearless Zerg are invincible. Until they meet more belligerent and despicable humans, they are invaded and even hit at home.

"Attention, change to defensive formation, guard the entrance and exit, and wait for the following troops to join"

Alva yelled on the communication channel, took out a honeycomb rocket launcher from the space ring, and turned back to be a series of shelling, which directly blasted all the insects chasing them out of the tunnel into fragments.

At Alva's command, 50 elite soldiers responded quickly. Under the guard of some, the rest quickly took out various parts from their own space equipment and assembled them.

In Li Xingyun's surprised eyes, five mobile tactical platforms were built by those soldiers in less than 10 minutes.

Each of the five six meter high tactical platforms was extremely spacious enough for 70 to 80 people to line up on. However, most of the space on the tactical platform was filled with weapons.

A series of heavy weapons, such as double barreled Gauss machine gun, extra large six barrel Gatling, honeycomb rocket launcher and Gauss heavy machine gun, have appeared on the tactical platform.

After a period of self-examination, the tactical platform controlled by the intelligent brain extended six spider legs from the field, and the tactical platform, which was six meters high, was once again raised by two meters.

After a short assignment, 25 of them jumped onto the tactical platform, manipulated all kinds of heavy weapons on the platform, and began a new round of killing of the oncoming insects.

Under the leadership of Li Xingyun, the remaining 25 people served as the guards of the tactical platform to prevent the powerful insects from breaking through the firepower blockade and jumping onto the platform to cause damage to the tactical platform.

At the same time, Li Xingyun saw that other Terran troops also followed Li Xingyun's example. They built up a series of tactical platforms. However, compared with Li Xingyun, these mobile tactical platforms were much simpler, with a height of no more than five meters and a width of only 15 meters. The heavy weapons carried on them were much weaker than those of Li Xingyun.

But fortunately, the number of other troops is much more than that of Li Xingyun, and there are also many more tactical platforms established.

Li Xingyun looked around and found that more than 100 Simple tactical platforms were rising in the cave.

Li Xingyun believes that in places he can't see, and in the direction that is blocked by Zerg buildings, more tactical platforms are being built, becoming the most visible navigation light in the insect sea.

The next step is the Terran's best defensive campaign. A series of simple tactical platforms are constantly hammered into the wormhead like nails. The Terran troops are constantly converging, relying on this tactic to nibble at the Zerg's territory.

"The person who came up with this tactic is really a genius. He even used the defensive tactics that the Terrans are good at in attacking"

Li Xingyun couldn't help applauding the inventor of this tactic when he saw the situation in a very good battlefield.

Originally, the Terrans on the offensive side should be more headache, but after the proposed tactical platform appeared, the position between attack and defense suddenly changed.

Terran soldiers blindly build a tactical platform to provide a foothold for the follow-up troops. In order to prevent more Terrans from entering the cave easily, the Zerg have to change from defense to attack. The insects leaving the range of the Zerg turret suddenly become live targets, exposed to the Terran guns.

"Be careful, Zerg have to deal with it"

Alva's words make Li Xingyun's eyes shrink.

If you can rub Terrans on the ground for a time, are Zerg really so weak? Obviously not.

When a certain number of tactical platforms have been built, a building in the center of the Zerg is like a bloated tumor, and all of a sudden, there are disgusting grunts.Then a huge opening opened at the top of the tumor, and a bug the size of a human head flew out and flew into the sky like a dark cloud.

These are somewhat similar to honeybee bugs. After flying into the sky one by one with the abdomen of cyst, the muzzle of gun barrel is directly aimed at the tactical platform close to the distance.

The next second, countless sharp arrows of purple pus shot out.

More than a dozen tactical platforms and soldiers nearby were corroded by purple pus and turned into a pool of smoky liquid.

For the first time, the Terran forces suffered heavy casualties.

Li Xingyun frowned at the miserable death of those soldiers. Although he saw more death, he felt a little uncomfortable with such a miserable way of death.

Before the second casualty caused by the flying insects, the Terran commander also reflected that one surface-to-air missile rose with white smoke and tail inflammation, and carried out a covering attack on the sudden appearance of the flying insects.

A violent explosion filled the whole cave in an instant.

After the explosion and the fire disappeared, the dark clouds disappeared, leaving only the charred corpses of insects falling like rain.

"Fortunately, these insects are not strong in defense, otherwise they will be in trouble"

Li Xingyun breathed a sigh of relief when he saw that the insects had been wiped out.

Just when Li Xingyun thought that the Terran could occupy the peak again, Alva sneered and said: "for so many years, this insect is really not new. Can't the ambush tactics be used up when the cannon fodder is used up"

before Li Xingyun can reflect what Alva means, a huge black hole suddenly breaks through the top of the cave.

Countless flying Mantis scrambled to climb out of the black hole, and then launched a suicide charge against human beings.

"The second fire echelon fires"
