The cooperation between insects and demons is far more tacit than human beings.

    To be exact, it''s because they really don''t seem to have a fear of death, only know crazy attacks. And compared with previous battles, Zerg and Demons now have more rhythm and level in attack.

    They know to put their companions who have long-range attack means behind, stay away from the front line, and use some hard skinned and fleshy insects to defend and block them.

    And those with strong mobility rush to the front.

    First the triangle iron was responsible for cutting, and then the terrible jumping ability suddenly jumped up from behind.

    Wave after wave of offensives, people are overwhelmed.

    It''s also a loss that 400 seven star killing mecha are blocked in front this time. If it''s still the same lineup as before, I''m afraid it won''t last for half a minute and will be torn to pieces by insects.

    However, even four hundred seven star killing mecha are like small boats in a storm.

    The leader of the mecha group, the Star School of Ji''s family, kept shouting on the internal communication channel: "space base coverage! Space based coverage! "

    With his shouting, air-based weapons covered the surrounding area with fire based on the mecha battle group.

    The polarized gravitational beam, like a silk thread, carefully ploughed all the places nearby. It can be said that there is no grass in the place.

    This kind of ray that can kill the enemy at the atomic level is not something that insects can resist. Even those demons have no chance to survive.

    In fact, human weapons are still very powerful. The reason why the scene looks so difficult is that there are too many enemies.

    There are holes made by insects everywhere. They keep climbing up from the holes, as if they were endless. You don''t know how many insects are hidden underground. It even makes people feel that the whole planet has been hollowed out, all of which are insect eggs underground.

    Otherwise, how can there be so much.

    The seven star killing mecha group has begun to lose.

    Due to high-intensity combat, more than a dozen mecha have insufficient energy or excessive wear at some positions, resulting in a sharp decline in combat effectiveness.

    Moreover, the insects seem to have become smarter. They know that if they fight positional warfare, they are equivalent to sending vegetables to humans.

    As long as the seven star killing mecha group blocks their way here, air-based weapons can launch unbridled attacks nearby.

    Therefore, a group of insects suddenly dragged the mecha out.

    It was not until the mecha was hundreds of meters away from the big team that they rushed up. In an instant, the mecha was torn to pieces.

    Even the sixth generation nano Er alloy can not completely stop the attack of these insects. After all, although nano Er alloy is strong, it is only used for protection. The active parts of many joints always leave gaps.

    As long as there is a gap, it is a weakness.

    Once it worked, the bug soon began its next attack.

    One mecha was dragged away. The one star school of Ji''s family saw fire in his eyes. He knew what would happen if the mecha was dragged away. The parts that kept emitting black smoke 100 meters away had told him the result.

    But he had no way to change. These insects had great strength. Together, they couldn''t even stop the mecha.

    He can only shout on the internal communication channel: "pay attention to the protection position, don''t leave the team, close to the laser sword!"

    A group of mecha immediately launched the airtight, fully automated shoulder laser gun of close-up laser sword dance at the critical moment.

    Although it is only the minimum power, it is enough to give these insects a fatal blow.

    However, the shoulder laser gun consumes a lot of energy. The mecha powered by nuclear power for the time being can''t fight for a long time, so we have to save some money.

    Unless it is dragged away, it can be used recklessly. Otherwise, once dragged away, it will be dead. What are you doing with energy.

    But even so, the loss of aircraft armour group is still quite large. If a large number of UAVs did not carry out ultra-low altitude crazy bombing regardless of the lost low space, they might not last that long.

    And even if mecha can hold on, human consciousness is difficult to hold on.

    Those who can join the seven killing star mecha group are strictly trained. They are much stronger than ordinary people in both mental and physical strength.

    But training in the virtual world is completely different from real combat.

    The loss of spiritual power in the real world is much greater than that in the virtual world, which is the biggest difference.

    After dozens of hours of continuous combat, those with slightly weak willpower may be unconscious on the spot.

    Last time, the double guards hanged only at the critical moment. They only played for more than ten hours. After returning, the two operators rested for several days to slow down.

    This time, the seven killing mecha has deliberately adjusted for the loss of mental power, which is much better than the previous Shuangwei mecha.

    But no matter how good, there are limits.

    Dozens of hours later, the first self defeater of the mecha group appeared, his consciousness suddenly disappeared, and the mecha stopped on the spot.

    The one star school thought it was an accident. When he learned that it was because the operator fell into a coma, he suddenly realized that he couldn''t fight any more.

    If you keep fighting, you''ll really die.

    Looking back, the engineering team has basically completed the construction of a network.

    He clenched his teeth, shouted to let the mecha group retreat, and ordered the engineering team to open the ray defense network of the sky and earth net.

    Through the last experience, the engineering team has been very clear that there are only two kinds of work that need to be completed immediately.

    One is to strengthen the ground to prevent insects from climbing up from the ground. The second is ray defense network, which can effectively prevent enemy attacks.

    So when they came to the place this time, they immediately dug up the ground and began to pour molecular polymerization agent.

    In dozens of hours, enough molecular polymerization agents have solidified a large area of land nearby, and the ray defense network has been installed and is undergoing final debugging.

    But now there is no time for them to debug. The seven killing star mecha battle group has been overdrawn, and up to now, it has lost more than half.

    If you continue, you really can''t do what you want, and the loss is not proportional to the harvest.

    Therefore, the Ji family two-star school responsible for the whole battle on the high-altitude warship also agreed with the idea of one-star school on the ground.

    All personnel retreat, return to the sky and earth net, and rely on ray defense to defeat the enemy.

    According to past experience, as long as the ray defense network can work effectively, the enemy will withdraw by itself.

    They know very well that with constant energy, this defense network can not be broken.

    No matter how many lives are filled, they just add a little more fun to mankind.

    When all the surviving seven star killing mecha returned to the safe area, the chief engineer of the engineering team pressed the official start button of the ray defense network.

    In silence, the airtight energy ray network rises around.

    Those insects that came under siege and were caught off guard were immediately cut into pieces.

    After a large number of insects and demons were chopped up, they stopped wisely.

    Occasionally, a few devils that could blink ran in and were immediately captured and destroyed by automatic weapons.

    Everyone was relieved to see that the insects and the devil had stopped attacking.

    A few minutes later, the insects and Demons began to retreat. When they quickly disappeared from human vision and returned to the underground cave, people began to cheer wildly after taking a breath.

    The second resource security zone has been established successfully!

    This success is no less meaningful than the first time.

    The seven star killing mecha battle group has tested its achievements in actual combat, which is quite good. And thanks to the role of mecha battle group, the personnel loss is minimized.

    Except for a few unlucky people, the consciousness collector in the mecha battle group was accidentally destroyed, resulting in brain death. There were almost no casualties.

    The casualties of ordinary soldiers in charge of internal defense are slightly larger, because they must confront the incoming demons and insects head-on. Even with the help of various automatic weapons and combat vehicles, hundreds of people were lost.

    For human beings, losing some money is not very important. Human life is the most precious.

    The success of this time has also completely laid the battle mode in the future. As the absolute main force and ordinary soldiers, the mecha battle group should not appear as far as possible.
