Even if Chi Mo was the supreme military commander of the base, he could not leave two soldiers to protect An Xiaoyu during the war preparation period, so after the "pickle tank" and "teaching materials" sent An Xiaoyu to the ward, they left immediately and rushed to the periphery of the base to return to the team to set up defenses.

Coming in from outside the base, it took less than ten minutes in total, and what was still ringing in my ears just now, the roar of the beast tide rushing in the distance, and the deafening deafening passing by the mecha vehicle, I couldn't hear anything inside the base, as if I had arrived in another world. An Xiaoyu wandered in her room, her heart irritated.

And at this moment, in the easternmost part of the base, the battle has begun.

The beast tide in the Eastern Desert has been around for a long time.

In the vast desert, people can't imagine that there are still creatures that can overcome all the harsh conditions such as drought, heat, and hunger, and survive in the sea of sand for countless years. However, every person in the Eastern Wilderness, every person stationed in the Eastern Wilderness, knows deeply that such creatures are more ferocious and terrifying than the fierce beasts in the deep mountains and old forests.

Because in their countless generations of survival history, they have to face not only the threat of other species, but also the unchanging harsh environment.

Some of these creatures live in the floating sand layer on the surface of the desert, some in uninhabited oases, some on the edge of the earth's crust tens of thousands of meters close to underground water sources or magma, and even some of them move with the wind and live in the dust floating in the sky.

After countless years of reproduction, the biological population in the desert began to be fixed, the resources began to be stable, and with it, the rush for survival. When the population reaches a saturation state, the creatures of the desert become alert and begin to spontaneously carry out an act of bloodline inheritance to ensure the survival of the race - the run.

That is, what humans call it, the beast tide.

In order to save the only survival resources in the desert and for the continued reproduction of the race, they abandoned their bodies and lives that had begun to slowly decay and stale, and ran desperately in the direction of the long mountains of the East China Sea.

It may be difficult to see one or two desert creatures from the top of the sand dunes overlooking the sand sea in peacetime, but they are hidden in the vast expanse of the Eastern Desert, and have accumulated unimaginable numbers for thousands of years.

Some of these insects and beasts that run away from home have a short life, some have a long life, some have an extreme living environment, and some have slow life activities, resulting in unpredictable random bursts of beast tides in the Eastern Desert.

They are large or small, acting alone, or several races acting at the same time. But there is no doubt that no matter where the tide passes from, whether their purpose is great or lowly, this act is a devastating disaster for the creatures that pass through it.

In the process of rushing towards the long mountains of the East China Sea, most of the creatures burned out their vitality and stayed in the desert where they were born forever; The life of some creatures is extremely tenacious, and they reach the Changshan without stagnation across the entire desert, and they are forever sealed in the bitter cold of the Changshan Mountain; Eventually, the few remaining beasts survived the scorching heat and the cold, and they stood at the foot of the mountain and looked out at the East China Sea, facing a water they would never understand, and rushed into it.

This is a test of nature, this is a brutal conquest. The stoic creatures in the Eastern Desert ended their obscure lives in such a brilliant way after a lifetime of silence in the sea of sand.

In the Three Thousand Empires, it is not unreasonable for scholars and literati throughout the ages to praise this feat of the Eastern Desert with great praise. However, at this moment, for the people of the Shahai base, they have no time to care about the cause and effect, and they also have to fight for their lives.

The cannon fired, the sonic weapons were fired to maximum power, and everyone, under the protection of the fortifications, raised their weapons in their hands and fired bullets at the rapidly approaching large patch of sand and dust in front of them.

Chi Mo stood in the center of all the troops, calmly commanding. The troops around the base are divided into five parts:

First of all, there are divided forces armed with cannons, sonic weapons, and heavy weapons, and their job is to concentrate their firepower into one point and tear a gap in the center of the surging beast tide with the threat of life.

Around the division of the troops, there is an expanded force composed of mechas, which is responsible for protecting the division force to ensure firepower, and at the same time, when the beast tide is close to the base, the gap opened by the division force is widened, which is enough to make the beast tide miss the base and continue to advance.

When the beast tide staggers forward from the base, the defense forces around the base and rely on the hard fortifications are responsible for ensuring that the cracks of the beast tide do not shrink and invade, and at the same time, they will also strike at the scattered beasts that break away from the beast tide.

In contrast to the division of the troops, in the direction of the departure of the beast tide, the tail sweeping force will observe and monitor the departing beast tide to ensure that when the beast tide leaves, it will not affect the normal operation of the base and prevent the beast tide from staying and retaliating.

Finally, a mobile team of elite troops is on standby on the periphery of the base, ready to fill the gaps caused by the loss of personnel and damage to equipment in any direction. This group is the most elite soldier in the base, and can withstand the tremendous pressure in a short period of time to ensure the smooth repair of the gap.

In the armies of the Three Thousand Empires, there are four types of individual weapons that are equipped as standard:

The first is the most basic type of cold weapons, including tactical knives, tactical axes, and sapper shovels, which have been used for countless years, as well as chainsaw heavy sword weapons with power, as well as a wide variety of throwing, trapping, and shooting weapons.

The second, which has also been used for countless years, is a live-fire weapon. A bullet with a large amount of kinetic energy that is fired out of the bullet can be used to deliver a strong blow to living creatures. Due to its mature development, simple principle, and great destructive power to organic life, it is widely used in the battle against living organisms.

The third type is the energy bullet weapon integrated by new technology, commonly known as laser weapon. Using the concentrated energy bombs, the high temperature and explosion generated to produce damage, mainly used against heavy armor and unmanned troops, the high temperature and strong penetration generated can cause double damage to electronic equipment and armored equipment, but because the high temperature can instantly stop bleeding, the penetration is too strong, and it can only cause simple penetrating injuries to living beings.

The fourth is the blasting class, including *, *, * and so on.

As the most obvious weapon for biological strikes, live-fire weapons are stored in large quantities in the base, and when the beast tide comes, the giant insects that bear the brunt of the attack are wrapped in countless small insects, or run or fly to the base, and the high-power sonic weapons broadcast a variety of insect-intolerable bands at high frequency.

Countless insects were shocked by the sound wave because of their low life level and lack of intelligence, and even most of them died directly, and the other insects that followed began to disperse due to the threat of life, leaving the area of the sound wave impact.

The division of the army will have to face the remaining huge insects.

It's a wave of bugs.

Huge insects, including the sand sea centipedes encountered in the incident of the Ann Xiaoyu train, there were hundreds of them as far as the eye could see, and their huge bodies were winding and coiling, and countless pointed feet pierced into the sand, raising bursts of sand and dust, and their hard bellies hit the ground with a deafening roar.

There are also beetles that live in the crevices of the rocks underground, with thick and hard shells, thick and thick limbs that roll up large sand waterfalls when they land, small eyes hidden in the carapace sweep around, and mouths make tooth grinding sounds that make people sore.

The flying insects flying in the air, with their sharp mouthparts hanging low, pose a huge threat to the base garrison without a large-scale air strike force, and the air tremors brought by the rapid flapping of wings, and the fluttering body shape and huge compound eyes make the back of the neck cold.

There were also scorpions with velvet claws, long-legged spiders, and some monsters that were completely different from the creature of the interior, with huge insect roars, and rushed towards the base with reckless speed.

Chi Mo calmly watched the sand and dust getting closer and closer in the distance, and the soldier's hand tightened the handle of the gun, silently waiting for the swarm to enter the best firing distance of the weapon. Under the incessant bombardment of the giant artillery, Chi Mo's eyes froze, and he shouted into the communicator:

"Hit!"

The gunfire was like thunder, and the bullets rained down like a torrent of bullets.

The giant beast in front was hit by five or six armor-piercing bullets, and several smoke-emitting bullet holes instantly appeared on the hard carapace, and then, the deformed bullet head passed through its fragile body inside, and the impact force did not weaken, breaking out behind it, carrying a large amount of yellow-green juice and minced flesh from the back, leaving a huge conical hole to accompany it to the ground.

However, the death of his companion was particularly insignificant in such a life-ending attack, and the insects behind him trampled on the dead corpses in front of them and continued to move forward, being shot, falling, and being trampled into the sand, and then another group of insects disappeared in the hail of bullets.

Gradually, as more and more insect corpses fell in front of the line of fire, gradually accumulating in the sand, the following zergs also began to be cut by the fire, forming a knife slit, cutting the invisible swarm in half, and the base was just in the center of the knife slit.

After the slit is formed, the pressure of the divided troops is instantly reduced by at least half, and it is only necessary to continue to shoot forward to prevent the separation of the slit from beginning to close, and the rest will be handed over to the comrades in the other parts.

The mecha troops in a triangular defensive formation stood on the periphery of both sides of the divided troops, forming an expanded firepower network to carry out fire strikes on the Zerg that were running separately to both sides. The indestructible shell, stable performance, multi-party strike ability and the initiative of hand-to-hand combat allow the mecha unit to expand the knife gap, protect the divided troops, and resist the encirclement of insect swarms, while also being able to take into account the flying insects in the sky.

The defense of the base, which lacks the ability to strike against the air, can only rely on the strafing of ground forces to resist the attack of flying insects. At the rear of the front line, some soldiers raised their guns and fired wildly at the flying insect swarm, but the flying insects were too mobile, and soon some insects broke through the defense line and entered the defense line.

With a shuddering insect chirp, the flying insect quickly selected the target and swooped down, grabbed the soldier among his forefeet, and quickly circled high in the air, inserting the sharp mouthparts into the soldier's spinal cord, with the squirming of the yellow abdomen, the soldier shrank at a visible rate, and waited until the soldier's blood, internal organs and bone marrow were all sucked dry, and the flying insect threw the corpse down, and the soldier who fell to the ground was left with only a skin sac composed of bones and muscles.

Chi Mo immediately ordered the remaining mechs to rush to the area of the flying insect invasion to disperse, cover the soldier troops under the mecha, and cooperate with the soldiers to strike at the flying insects, so as not to cause the collapse of the defense line. With the cooperation of the mecha, it barely defended against the threat in the air.

The situation on the battlefield seems to have become manageable.

However, Chi Mo's brow furrowed slightly, and he used his telescope to observe the battlefields everywhere, receiving reports from various parts of the army, and found that there was nothing abnormal. But in his heart, there was always a trace of uneasiness, this was a kind of alertness to the battlefield, and it was his intuition after experiencing more than a dozen battles against the beast tide.

He felt that there was still some threat, and they still did not see it.
