Now, in the middle of Liu Qingshan's survey, those biological warships with alien satellites are constantly launching one small fighter plane after another, and they are bombarding their own defensive positions above the ground. In this case, although all of their mammoth tanks have turned on their air defense combat performance, it seems that the air defense capability of these mammoth tanks is not able to cause much lethality to those alien alien ~ carrier-based aircraft. So, not long after, seeing that the light wave cannon array was already crumbling, it seemed that it could no longer support it for too long.

At the same time, those mammoth tanks also seem to be taken care of outside of class. After all, they are the only ones who can carry out an air defense attack. As a result, I saw a dense number of alien alien biological carrier-based aircraft, and they launched fierce attacks on them one after another. One by one, beams of light shot down from mid-air, intimacy, and it seemed that between the heaven and the earth, it was almost a sea of laser beams. Under such ferocity attack, even a mammoth tank, which was known for its superior defense, was ultimately unable to withstand it, and three of them were quickly destroyed before long.

In this case, Liu Qingshan had already killed the red eye, randomly named the assault combat unit, and pulled all of them up. Among them, seventeen squads of missiles. These missile squads are capable of launching anti-aircraft missiles, and they are more powerful than mammoth tanks. So, in this case, although those members of the missile crew finally shot down more than a dozen alien alien biological carrier-based aircraft, after all, the number of those biological carrier-based aircraft on the other side was too large, and it seemed to cover the sky, so the final result, together with the light wave cannon array, and the remaining mammoth tanks, was now basically completely under the siege of that dense biological carrier-based aircraft.

－－－－－－－－－－－－－－－－－－－－－－－－－

For a time, the situation seemed extremely dangerous. Yes, although it is said that those mammoth tanks under Liu Qingshan, as well as those members of the missile troop squad, in peacetime, have very good air defense combat capabilities. However, it seems that the biological carrier-based aircraft of those alien alien creatures are born with a certain immunity to this kind of anti-aircraft firepower, although on the ground, to the mammoth tank to the squad of those missiles, the firepower is strong, and it can be regarded as going all out, but, in the end, the number of biological carrier-based aircraft of the alien alien creatures that have been shot down is still very limited.

In addition, after all, the biological carrier-based aircraft of those alien alien creatures are becoming denser and denser, flying out of the air warships one after another, and it seems that there is no end to it. In this case, Liu Qingshan finally realized that from the beginning, he had entered a misunderstanding. Yes, it is. I only cared about it, and tried my best to attack those biological carrier-based aircraft, but even if I could shoot down more biological carrier-based aircraft, it would not solve the problem. Because, there will still be a large number of biological carrier-based aircraft, constantly flying out of those aerial battleships.

In this way, the real culprits are those few suspended in mid-air ~ alien biological warships. As long as you can shoot down those alien biological warships, or directly destroy them in the sky, then the problems you are facing and the grim situation you are facing will be solved immediately. However, Liu Qingshan also took into account that those small biological carrier-based aircraft already had a kind of dedicated immunity to their conventional anti-aircraft firepower. What's more, those behemoths suspended in mid-air. What's more, now, in their own hands, on the ground, those mammoth tanks and those missile squads have been damaged, and they are no longer able to organize an effective air defense attack.

The situation became more and more critical for a while. Yes, Liu Qingshan didn't expect that things would turn out like this. Prior to this, although Liu Qingshan had also envisioned the worst possible situation, it was also the alien alien side, which might preside over a larger-scale ground offensive. However, with that light wave cannon array, and his own military base is now basically perfected, he can completely transport mammoth tanks to the frontline positions in a steady stream. Thus, it should be possible to further consolidate and strengthen the firepower of their frontline positions, so that they can block the attack of the alien alien side (the attack here is, of course, the ground attack).

However, he didn't expect that the alien alien would actually send such an aerial biological warship. This kind of alien biological warship, it seems, in order to form a huge, very peculiar, strange shape, from the appearance, there are no rules. However, the attack capabilities of the small biological carrier-based aircraft released by them, especially the ground-to-ground attack capabilities, are indeed not to be underestimated.

Even if it is a large array of light wave cannons, the defense ability is so strong, for quite a few years, it has been implemented by the evil alliance side, which is invincible in the world, but in the face of the crazy bombing of those biological carrier-based aircraft, it is already crumbling, and it is precarious. In this case, Liu Qingshan knew that for the time being, he really had no better way to deal with those satellite biological warships.

However, despite this, Liu Qingshan's thinking was still very clear at this time. As a commander who has fought on the battlefield for many years, he knows that the top priority is to further organize forces and resolutely block possible ground attacks from the enemy.

Yes, it is. Liu Qingshan knew very well in his heart that no matter how powerful the biological carrier-based aircraft of those alien alien creatures were, it was not so easy for them to destroy the military base they had just occupied. However, if the ground combat forces of the alien aliens were allowed to break through their first line of defense through the stone bridge in Guò, then once they entered their own military base, or only surrounded their own military base, the consequences would indeed be unimaginable.

After all, ground fire attacks are more direct, more effective, more violent, and more deadly. Therefore, in the face of such an unfavorable situation, it is obvious that Liu Qingshan's choice is still very correct. That is, to take the lead in further strengthening its ground defense, and strive to make it impossible for the ground forces in the satellite alien to break through its own forward positions lightly, and only in this way can it be possible to win more time and formulate the next combat plan to deal with those satellite alien air biological warships. Otherwise, once the opponent's ground attack force rushes over, at that time, no matter how powerful you are, you won't have the power to return to the sky.

Therefore, after thinking of this, Liu Qingshan mobilized almost all of his ground combat forces to the forward positions to further strengthen the defensive combat capability there. At the same time, ~~~~ Liu Qingshan made full use of the production and construction funds accumulated by himself during this period of time, and rich resources, and worked hard to produce the Door Cattle Dog Chariot. He knew that among his combat units, the only one that really had professional-level air defense capabilities was this kind of Men Niu Dog combat vehicle. Second, neither the Mammoth Tank nor the Missile Troopers can pose an effective threat to the biological warships of those alien alien creatures. However, it is not impossible for his own Door Cow Dog Chariot to become the nemesis of those alien alien creatures in the air battleship.

Now, the development of the shape shì, as Liu Qingshan expected, in terms of satellite alien creatures, those few biological warships actually slowly left the forward position and no longer launched an attack on Liu Qingshan's forward position. Instead, he flew in the direction of Liu Qingshan's military base.

Obviously, the reason why the other side made such an adjustment is because the fundamental purpose of the other side is its own military base. However, the alien aliens' attack on Liu Qingshan's forward position did not stagnate. Just as Liu Qingshan expected, although the air attack was over, a large number of ground combat troops swarmed in.

In this case, what made Liu Qingshan feel very helpless was that his light wave cannon array had now been completely destroyed by the air biological warships of some alien alien creatures. Since then, Liu Qingshan's main reliance on positional defense here has disappeared.

Under such circumstances, in the face of the various ground attack firepower units that were swarming like a tide of alien alien creatures, Liu Qingshan could only rely on the dozen or so mammoth tanks that had just come over to support him, desperately blocking the attack. Fortunately, his own mammoth tanks have always been known for their particularly strong defensive capabilities, so the dozen or so mammoth tanks are arranged in a straight line, forming an extremely strong defense line, which cannot withstand the crazy attack of those tidal alien creatures.

It's as if they have built a great wall of steel, and with their bodies and powerful artillery attacks, they are fighting to the death against those crazy alien alien creatures. However, Liu Qingshan also knew that even this Great Wall of Steel was in a difficult situation, but after a long time, in the face of the crazy attack of the extremely crazy and seemingly innumerable satellite ground combat troops, in the end, ~ a Great Wall of Steel would also be exhausted.

At the same time, Liu Qingshan has already produced more than a dozen Menniu dog chariots and deployed them at the forefront of his military base. In this case, Liu Qingshan is able to use the guò kind of door cow dog chariot to deal with the alien alien biological warship La. In addition, judging from the current situation, Liu Qingshan has no other good way.

However, intercepting with the Fire Eagle fighter is also a combat plan, but Liu Qingshan is not sure what the effect will be. What's more, now, he has just built his first airfield, and the production plan for four Fire Eagle fighters is also underway. Due to the high cost of this Fire Eagle fighter, the production cycle is also very long.

In this case, it is still unknown whether this Fire Eagle fighter can be formed into combat effectiveness before the arrival of the enemy's biological warships. Therefore, judging from the current situation, Liu Qingshan can only pin his hopes entirely on the dozen or so menniu dog chariots. Hopefully, their air defense capabilities, that kind of professional-level anti-aircraft firepower, can stop the arrival of those biological warships of alien alien creatures. At the very least, it is necessary to win a longer period of time for their Fire Eagle fighters to finally form combat effectiveness.

At the same time, Liu Qingshan was also very worried about his frontline position outside the stone bridge. Although there are a few mammoth tanks, forming a great wall of steel, they are defending themselves against the attack of the tide of alien alien creatures, and at the moment, there is no serious problem. However, as time goes by, what will happen, Liu Qingshan does not dare to think, let alone say. This is because he knows that the situation will be dire and the danger will be greater. Once the steel defense line formed by his dozen or so mammoth tanks is destroyed by the other side, those alien alien creatures will be out of control and use them wildly in their military bases. At that time, it will be really late.

Even now, although the dozen or so mammoth tanks defended with all their might and ended up with all their might, Liu Qingshan saw that at least four to five of them had reached the limit. The armor on their bodies was mottled, and almost every combat vehicle emitted billowing black smoke. For this kind of mammoth tank, Liu Qingshan is very familiar. As his main chariot, he has made many peace and war exploits for himself, and his merits are outstanding, and it can be said that he has always been Liu Qingshan's favorite.

At the same time, Liu Qingshan is naturally so familiar with this mammoth tank that he can hardly be more familiar with it. Therefore, he saw these mammoth tanks, mottled all over, constantly revealing billowing black smoke, and some even began to emit dark red fire, which meant that they were not far from the final explosion. For a while, Liu Qingshan was anxious, but he had nothing better to do.

However, at this time, Liu Qingshan suddenly had a flash of inspiration, if he could build a maintenance facility in his forward position to provide a certain amount of health repair for those damaged chariots, in this way, he would also be able to solve some problems. At the very least, that great wall of steel would not have been destroyed by the enemy so quickly. However, it is not easy to build a real building with the function of vehicle maintenance.

However, Liu Qingshan knew very well in his heart that under the current situation, it was basically impossible to build a real tank factory that could provide repairs for the damaged tanks in his own forward position. Because it's too late. However, it is possible to produce a mobilization vehicle to replace the tank factory and perform the function of repairing damaged vehicles.

Because this kind of mobilization vehicle, the cost is relatively low, and the production speed is relatively fast, therefore, it is in line with the current needs. So, after thinking of this, Liu Qingshan's order began to produce this kind of mobilization vehicle. However, at this time, the alien alien creatures had already flown over. Looking at the few alien alien creature warships in mid-air, it seemed that they were covering the sky and the sun, domineering, and invincible, according to the plan, Liu Qingshan couldn't help but be surprised. Yes, in the face of such a powerful air strike force, to be honest, he doesn't have a bottom in his heart at all.

Fortunately, before this, Liu Qingshan had already produced more than a dozen Menniu dog chariots and deployed them on the periphery of his military base. In this case, relying on the professional-level air defense capability of the Door Bull Dog Combat Vehicle, it should be able to deal a certain blow to those alien alien biological warships. Sure enough, at this time, an air-to-ground battle between the two sides finally kicked off.

On the ground, Liu Qingshan's side was seven Men Niu Dog Chariots, trying their best to shoot out the secret squeezed surface-to-air missiles towards the flying biological warships in mid-air. Whizzing, swishing, dense anti-aircraft missiles, whistling, from the ground above those Men Bull Dog Chariot big battle missile launches, constantly bursting out, breaking through the air, whistling, dragging the snow-white tail flame, constantly changing the direction of flight, constantly correcting the trajectory of flight, and finally, one after another, hit the target in the air.

Of course, in this case, those biological warships, faced with such a frantic attack on face value, immediately began to fight back. I saw that from those biological warships, one after another small biological carrier-based aircraft were ejected, and those small biological carrier-based aircraft, although they were not very big, they looked like small birds, but their flight speed was very amazing. Suddenly, it was like a black streamer, in the night sky, it looked very mysterious, and it was even more terrifying.

Then, those small biological carrier-based aircraft continued to shoot black laser beams one after another towards the ground. These black laser beams, extremely powerful, carried a terrifying evil aura, and slammed into Liu Qingshan's door bull dog chariots on the ground. You must know that those Door Bull Dog Chariots are not very strong in their own defensive capabilities, and in the face of such a ferocious attack, in the blink of an eye, three of them have been completely destroyed. On the ground, the group's dark red explosion suddenly flashed, and Liu Qingshan's heart trembled incessantly. He knew that this basically meant that the air defense front that he had carefully constructed and composed of more than a dozen men cattle dog chariots, it should be said that the effect was not ideal.
