The battle between the front-line mecha troops and the swarm lasted a total of ten hours.

The casualties of the mecha unit have been more than half, leaving pieces of mecha parts on the battlefield. In the very center of the battlefield, there were also many pilots, all of whom ran out of the scrapped mechs after being destroyed by bugs.

The mortality rate of these people is much higher than that of other people.

All they have left is exoskeleton armor and guns, but they have to face the Zerg army directly, and under the knife of the bugs, the pressure of these people can be imagined. There are also some lucky people who are scarred, but have a chance to withdraw from the battlefield. On the battlefield, you can also see a lot of mecha that have already transferred their tracks. These people's mecha were all injured in their legs, and they had to become like this. And in this state, their attack power is also plummeting.

But that's enough for now. The number of swarms can be counted.

Before, it was just an overwhelming situation, and at a glance, it was all insects. But now, the number of biters is basically able to get an approximate number.

The shelling of mechas, the bombardment of combat aircraft, coupled with the firepower of the marines, the casualties of the bugs were much greater than those of humans. And the battle of this intensity lasted for ten hours, so that the swarm could not bear it.

As the battle came to an end, even the bugs began to be afraid, and the few bugs that were left began to retreat.

The human troops did not pursue again, but stayed in place and began to rest.

The casualties of bugs are enormous, and the number of human casualties is not small. The materials consumed are not counted first. The mecha of the mecha unit alone lost more than sixty percent, and the death rate of the driver also increased by forty percent. The mecha supplied from the rear can only ensure about half of its combat strength, and the rest can only be temporarily transferred to the marine soldier unit to fight.

It's just that these pilots are used to fighting with mechas, and next, their combat effectiveness is inferior to that of an ordinary marine soldier.

But it's a combat power, an extra gun. It's always good, right?

Supplies from the rear are also being continuously delivered to the front line. Resupply ammunition, medical supplies, energy and much more. The shells and cannon ammunition of the mecha were also fully replenished.

It took two hours to rest. And that's fast.

But for Yang Hao and others. This speed. It's too slow.

If you calculate it, they have less than five hours left. Next up is attacking the hive. Whether they can persist until the end, they don't have a little bottom in their hearts.

Fortunately, at this time, the army moved again and headed towards the hive, which was already not far away. The combat aircraft in the air have also taken the first step to make the first attack.

The sound of explosions was already heard in the distance, and the mechs were still resupplying, but the marines had already begun to move, heading to the sides.

They will never go deep into the depths of the battlefield, it is just an act of sending them to death, and they will only give fire help to the mecha troops on the side of the battlefield, and the real combat effectiveness is still these mecha troops.

The reconnaissance information in the sky has also come out, and the Zerg have now built a line of defense near the Worm Hive, and the number of Worm Swarms is still very large, but it is not as large as before.

Although the breeding of zergs is terrifying, they also need time and energy, and in addition to that, space. This valley is so big, and the space also limits the number of Zerg in a certain way, so that they will not be allowed to reproduce indefinitely, so that the energy obtained by the Zerg will not be able to sustain it. I don't know how many bugs have been solved before, and the number of swarms that this hive has has been greatly weakened, and it is not a strange thing to have these bugs left.

In the past, in battles on other moons, mankind won in this way. It turns out that such a plan against the Zerg is the most effective.

Because with the ability of the Zerg, it is impossible to deal with such a strategy perfectly. On the human side, the frontal mecha troops are hard to resist, and the combat aircraft behind are bombed, and the number of Zerg is constantly consumed, and the supply cost is weakened, and the number of Zerg will eventually be completely consumed.

When the Marines reached their designated position, the aircraft were still bombarding the hive.

This position is a mountain, the height is not very high, in addition to this mountain, there is a valley around, very empty, the land soldiers, at this time appeared on the nearest mountain from here, but the distance between them is also more than six or seven hundred meters away.

On that mountain, you can see the figure of the Zerg everywhere, and in the valley, there are also all insects, surrounding the entire mountain, forming a tight line of defense. If the human army wants to attack the hive, it must first deal with these bugs. In the middle of the mountain, there is a huge hole, so big that two mechs can enter at the same time, and at this time, in the cave, there are still a lot of bugs coming out of it. It seems that this is the so-called hive.

Inside, there is a most special bug, the female. As long as you kill it, or catch it, then this battle can be regarded as a perfect victory.

The Zerg have a huge weakness, and that is that there are no species capable of flying. This weakness has been grasped by humans for a long time, and it is now being used to beat them.

The aircraft flew very high, back and forth, only dropping bombs down, bombing the bugs. And they can only watch obediently, waiting for the bomb to fall on their heads, but they can't threaten these flying machines at all, some flea-type soldiers jump high, but before they can touch the flying machines in the air, they lose the strength to rise and fall to the ground.

The next thing that greeted the bugs was a dropped bomb.

When the Marines came to the planned location, they saw such a scene.

As soon as they arrived, the Marines jumped into the fray, and a large swath of guns spewed out bullets again and flew into the swarm guarding the hive.

Some of the bugs started running in this direction.

The position of the Marines is only a few hundred meters away from the Zerg, and if you add the natural cliff obstacles, the two sides will meet in ten minutes. At this time, the engineers also built a defensive line on the way that the Zerg must pass to defend against the attack of the Zerg.

In a short time, a simple line of defense was built, and the soldiers entered and held the pass.

Even if the Zerg can break through this line of defense, it will have to pay a great price. And if this line of defense is broken, the troops in the rear will not be afraid.

So many people are waiting there, and as long as the Zerg dares to come up, they will definitely be sent to hell.

Not long after, the mecha unit also drove into the battlefield. These mecha troops were even more simply, and after seeing the Zerg's defensive front, they adjusted their formation without saying a word.

A barrage of shelling began again.

In the hands of the army, long-range attack weapons have always been the main weapons, and at this time they have not yet approached the Zerg, and using cannons to consume them is one of the most common, effective and safe means. The driver's life is also fate, if the number of Zerg can be consumed in large quantities when approaching the battle, that is the most desirable thing for any person.

The fewer enemies you face, the more likely you are to survive.

Of course, the Zerg couldn't wait to be blown up. They can't reach the flying machines in the sky, but the mechs are on the ground. When the mechs showed their heads, they rushed towards the mechs.

The insects are also charging with great momentum. From above, it looked like a black flood was coming towards those mechs.

Mecha units no longer fire salvos, but fire freely. The light and sound of the fire continued to sound, and from the side of the Marine soldiers, it felt like firecrackers were being set off during the New Year.

The explosion blasted one insect after another into the sky, and the remaining insects still roared and charged towards the mecha troops. This time, the mecha unit was even more dangerous, and put the insect fifty meters away from them before pulling out the alloy knife and starting to charge.

The battle was like a hand-to-hand fight a few hours ago, and it was once again in the middle of a close fight.

The second batch of aircraft entered the battlefield again. Their goal was to set themselves on the swarm of insects in the mountains. I saw that explosions began to explode everywhere on the mountain, and one by one the insects were thrown down the mountain by the explosion, and they fell heavily to the ground, and huge deep pits appeared in the place of the explosion, and even some places collapsed directly under the explosion.

This should be caused by the direct explosion into the inside of the hive, causing the load-bearing part of the interior to collapse directly.

At this time, a very special mecha unit broke away from the main force and began to rush towards the interior of the swarm.

It was like a sharp knife that plunged into the depths of the swarm.

These mecha pilots have a very special mission.

Seeing such an organized attack and defense of the Zerg proves one thing.

Inside the hive, there is also a brain worm that is stored in zài.

The mother worm does not have the ability to control the Zerg, and the Zerg will only form a scale when there are brain worms, otherwise, it will be a particularly large number of rabble. The reconnaissance team was already about to turn the area over, and they had not found the brain worm. Then the only place where it can store zài is inside the hive.

The mission of this special mecha unit is to break into the hive, find a way to find this brain worm, and kill it.

Killing the brain worm is equivalent to winning the battle.

The weapons on this mecha unit are also different from other mechas. Their weapons, in addition to the cannons on their shoulders, have also become somewhat elongated, making them more suitable for short-range contact combat. The two-handed cannon is also different, it has become a single-barreled cannon, the rate of fire has decreased somewhat, but the reload has increased, and the rate of ammunition consumption is much slower, which is more suitable for long-term battles.
