On the brown hillside that could not be seen at first sight, there were Zerg's construction and defense organs. Among them, the spore tower that fired spore bullets kept ejecting a large number of fist-sized spores from the exit above, like a fountain.

After these spores are sprayed out, they will not fall on the ground, but will fly in the air, blocking the entire sky where the Zerg's mother nest is.

If the flight troops want to fly from the air, or shoot missiles and shells bombard it, they will be intercepted in mid-air by these, strong acid spores containing acid liquid, or fibrinospores containing flame.

For this Zerg mother nest, it is no longer possible to use artillery fire to perform saturation bombardment like when attacking the scoring base before, which is of no use except wasting ammunition.

It is obviously difficult to advance directly from the ground, because the dense insects and ground troops will flood the people who are rushing towards you like a tide - because the three-discipline base were given up, the brainworms in this place had more than 200,000 worms under their command.

This number is much more than that of human soldiers anyway.

The brainworms in the mother's nest are very similar to the mother's brain in appearance. They are both naked brains, but they are far less huge and powerful than the mother's brain.

In recent times, when the Zerg was at an absolute disadvantage, this brain worm contacted the mother brain again and again through telepathy. What made it desperate was that the mother brain did not respond to any of its connections. As an extremely intelligent being, the brain worm understood that it had been abandoned by the mother brain.

Now, the brainworms in this nest have not given up. As long as they resist the attack of humans and eliminate most of the human army in the war, there will still be hope for a turnaround.

If the human base is turned off, it will no longer be a subordinate who fights for the mother's brain, but the insect king who truly ruled this planet.

The human army stopped in the sphere of influence occupied by the insect nest. The officers who came down from the chariot looked at the tall Zerg buildings on the hillside in the distance, the black bugs, and the spore bullets everywhere in the air, and each frowned.

The price of such a strong attack is too high.

When humans drove in here, they immediately suffered a charge from insects. Because the sky was blocked by spores, the wing membrane flying insects could not take off. These insects were mixed in the squad of swift beetles and rushed towards the human army. The scene of rushing down from the hillside reminded people of mudslides.

The insect tide-style attack is the Zerg's best at and the most threatening combat method.

A large number of soldiers in front pulled the trigger and fired bullets. The heavy tank quickly grabbed the ground and stabilized it. Then they opened their guns. Amid the deafening roar of shelling, the tide of insects continued to explode black flames and thick smoke.

During bullets and explosions, a large number of insects were pierced through the body or fryed into minced meat, but there were too many insects charging, and some scorpion chariots drove in and crushed with tank-like metal tracks.

After mobilizing combat units from three sub-bases, brain worms can give full play to the numerical advantage of the Zerg in this battle. Fierce insects are charging forward, including tank bugs with huge bodies, thorn bugs with spikes all over their bodies, and meat vine bugs with flesh tentacles stretched out from their bodies, and other advanced combat units.

The machine gun soldiers and scorpion chariots were soon overwhelmed by the charge bugs. Seeing the bugs attacking wildly, more than a thousand elite soldiers wearing exoskeleton armor rushed into the battlefield to fight with the explosive arrow gun and electromagnetic rifle, which barely stopped the bug attack.

In such a battle, Ling Xuan naturally rushed to the front line, holding a giant alloy sword close to two meters. Every time he cut through, a bug would be shattered.

The slash beetles were slashed with pieces of corpse. At this time, a flesh vine worm rushed up, and more than ten snake-like tentacles, with bone spikes at the top, burst into flames at him. The alloy sword blocked in front of him, and the firing tentacles hit the metal sword, making a loud impact.

Feeling the impact force coming from the weapon, Ling Xuan took advantage of the impact to retreat, and one back hit a swift beetle behind him, and another swerved his body, and used an alloy sword to force the insect away.

Seeing that there were insects around, the fleshy tentacles of the fleshy vine worms also shot at him again like a long spear. Ling Xuan grabbed the hilt with both hands, pressed his heel to the ground, and his body rotated. Under the centrifugal force caused by the rotation, the heavy alloy sword swept in all directions.

His body seemed to be a rapidly rotating top, cutting it along the ground towards the vine worm. The flashing golden light on the alloy sword covered his body, looking like a whirlwind of blades strangling at high speed!

This is a martial art that is purely driven by strength and skills. Ling Xuan has been fighting continuously over the past year, and of course his martial arts has improved. The rotating blade whirlwind hangs all the surrounding thunder beetles and rushes on the flesh vine worms. The huge flesh vine worm seems to be stuffed into the meat grinder.

The splattered flesh and blood fell on the surrounding ground and quickly covered a thick layer.

He used the blade whirlwind to cut a piece of the insect tide. Ling Xuan threw out several high-explosive grenades, used the grenade explosion to slow down, and then danced the alloy sword again. He saw several machine gunners resisting the insects back to back in the distance, as if they were very critical, and rushed over to save the person.

After rescued dozens of soldiers, Ling Xuan suddenly heard an alarm from the army. With the sound of the alarm, a strange car drove out. He quickly lay on the ground and covered his eyes with his hands.

As a missile painted red and black and extremely dangerous at first glance was shot out, the sky shone brightly, and the huge light made the stars lose their luster. A violent shock wave burst out from all sides, and at the same time a flame mushroom cloud rose.

Because the situation is critical, humans finally used nuclear bombs - of course, they are just super-small nuclear warheads.

This ultra-small nuclear warhead is far less powerful. Ling Xuan used the space jumping nuclear bomb to deal with the mother brain. It was a small tactical nuclear bomb with low radiation and low lethality. But even if the power is low, the nuclear bomb is a nuclear bomb after all.

The explosion of a nuclear warhead caused the shock wave spread across the sky, and the strong acid spores that were blocked in the air, destroyed or blown away. There were also three nuclear warheads that exploded several mushroom clouds in the insect tide, destroying tens of thousands of insects.

The other two nuclear bombs shot into the distance, blowing up a large number of defense organs on the hillside.

Five small tactical nuclear warheads - this is the limit of launch. No matter how many, the protective suits of the machine gunners cannot resist radiation, and will also cause serious pollution to the area.

The horror of radiation pollution is not only that it will affect humans themselves, but also mutate insects. Humans once used nuclear bombs to deal with insects, but as a result, some elite insects that absorb radiation mutated were extremely powerful, and some could even use nuclear energy, one by one to the extreme.

This time, if the insect tide was not too fierce and the humans suffered too much losses if they continued to attack, the military would not have launched tactical nuclear bombs.

Five tactical nuclear bombs cleaned up the blocked sky and killed a large number of insects' living forces. Human tanks, elite armored soldiers, and machine gunmen in protective suits started to move again after the flames of the nuclear explosion dissipated.

The insects that suffered a major blow were finally unable to resist. The tanks were pushed forward and crushed, the air fighter was suppressed, missiles, artillery bombing, and soldiers cooperated with the attack. More than an hour later, the human army advanced above the hillside.

Some organic buildings were destroyed one after another. Of course, Zerg's defensive buildings, such as the thorn tower, the spore tower, etc., also brought great losses to humans, and some tanks were destroyed. But no matter what, the victory balance of the war was tilted little by little, towards the human side.

The sky gradually became darker, and the Zerg organ buildings on the hillside were almost flattened by cannon fodder, and the corpses of the insects covered the ground.

Ling Xuan put on the power armor and flew from the air toward the nest of the Zerg base - that is, the peak of the hillside. After blew up more than a dozen flying elite insects with pulse rays, he looked at the peak in surprise.

I saw a nauseous brain meat piece with a diameter of about five meters and full of gullies, which was located on an unknown black and red fleshy organ. The organ had a huge mouth full of teeth, and a large number of insects gathered around. The fleshy organs continued to produce tentacles, wrapping the insects into it.

As the mouth chewed, these insects seemed to be swallowed and absorbed. The black and red fleshy organs became taller and taller, and the tentacle limbs produced from the organs became thicker and thicker. They even swept dozens or hundreds of insects into their mouths that also became larger at one time.

"Is this... devouring evolution?"

When Ling Xuan communicated with the mother brain, he once heard about this. The Zerg usually evolves through fighting, killing, and plundering the genes of other organisms. The mother brain has studied it and directly devouring the body of the insect. Although it can make the body bigger and stronger, such devouring evolution will easily disintegrate if the genes are unstable.

Obviously, the brainworm in this place chose to devour the insects when it could not resist the attack of humans, thus mutating into giant monster insects, and using the combat power that was lifted to the limit to fight against the human offensive forces.

It made waves of roars that seemed very painful, and the fleshy organs were pulled out of the ground where they were rooted. It now looked fifty or sixty meters high.

At the top of the organ, a brain that is the body of the brainworm is embedded. There is a giant mouth full of sharp teeth in the middle of the body. Some flesh tentacles with one meter diameter are dancing wildly.

From the appearance, it was so terrifying that the human soldiers who saw this scene were all stunned.

Incandescent light lit up in the mouth of this monster insect. Some elite insects can call the biological energy generated by the cells to defend and attack, and swallow tens of thousands of insects. After the mutation, the biological energy that brain insects can use has become so powerful that they can bombard the energy cannon! (To be continued.
