It should be said that this is the first time that the mammoth tank under his command has carried out an air defense attack after the upgrade of the science and technology center in Liu Qingshan's military base. Sure enough, at this time, under the impetus of the upgrading of the science and technology center, the anti-aircraft combat performance of this mammoth tank has been significantly improved. The anti-aircraft missiles they fired out looked like meteors, and their speed, reach, and scale had increased a lot.

In this way, several anti-aircraft missiles in succession soon hit the alien alien biological carrier-based aircraft in mid-air. And the specific result of the attack was that an anti-aircraft missile was able to shoot down a biological carrier-based aircraft. With such an attack performance and such a combat efficiency, Liu Qingshan finally had a bottom in his heart. Whoa, damn it, now it's okay, and now it's going to be the end of these alien creatures' biological warships.

In this way, after this period of fierce fighting, in general, the trend of the entire battle has entered the stage of stalemate. Since Liu Qingshan upgraded his science and technology center, in general, the level of attack firepower has been greatly improved, and since then, it has been an extremely deadly danger, especially for those biological air warships with alien satellites.

In addition, Xiang Liu Qingshan lost no time in sending a light guide vehicle to his forward position, so that he was able to provide a steady stream of health for the mammoth tank that insisted on fighting there. In this way, the Great Wall of Steel has been able to persevere. At the same time, Liu Qingshan also dispatched five mammoth tanks from there and returned them to his military base, so that the remaining Men Niu Dog chariots cooperated with each other and fought side by side, and finally, all the first to air warships in the alien alien side were shot down.

Subsequently, Liu Qingshan gave an order and ordered his newly formed air defense combat force to move towards the second air warship force in terms of alien aliens, however, at this time, the air attack force composed of seven alien alien biological warships was attacking Liu Qingshan's ore collection system. After seeing this, Liu Qingshan couldn't help but be surprised. He knew that the ore gathering system was a top priority for any military base. Yes, it is. Because that is the foundation of a base, the economic source of a base, and the lifeblood of a base's survival. It seems that the alien alien aspect is also very clear about this.

Yes, at this time, Liu Qingshan clearly saw that the biological warships on the alien side, the biological carrier-based aircraft sent out, were desperately attacking his mining vehicles. Those creature carrier-based aircraft, flying fast, powerful firepower, in mid-air, frantically shuttling back and forth, shot out one beam after another, hitting the target fiercely.

So, coax, coax, coax...... The explosions continued one after another, and in the face of such a crazy fierce and dense attack, even Liu Qingshan, who had seen the world, couldn't help but shudder. Yes, those biological carrier-based aircraft, it seems, are like dense hornets, almost pervasive, everywhere, flying frantically to kill by mistake, and the attackers, all the time, embody a bloodthirsty, brutal, crazy, killing spirit.

－－－－－－－－－－－－－－－－－－－－－－－－－

In the future, in order to strengthen his own economic construction, in the shortest possible time, he can collect the most Tybron ore resources, Liu Qingshan once produced seven mining vehicles at once. However, in the face of such a fierce air attack from the other side, coupled with the fact that, not long ago, Liu Qingshan was only busy dealing with another biological warship force, so those seven mining vehicles were almost attacked by this kind of biological carrier-based aircraft in terms of satellite aliens.

When Liu Qingshan finally drove over his improvised air defense combat unit, an air defense combat unit composed of five mammoth tanks and three Menniu dog chariots whose health had finally recovered, only four of the seven mining vehicles remained. Moreover, these four mining vehicles, discouraged, but not exposed, their health has been greatly reduced, and two of them are even constantly covered in black smoke. Chen apparently in this case, the two mining vehicles have been close to the edge of the ruined miè pull.

After seeing this, Liu Qingshan's eyes couldn't help but redden, and the sunlight was full of fatherly light. Now, with his own science and technology center, he has upgraded his attack firepower, both in terms of ground-to-ground attack and ground-to-air attack, which has been greatly improved. Under such circumstances, Liu Qingshan is still full of confidence in the ~ air defense combat squad that he has just formed.

That's really the case. Not long ago, it was with this air defense combat team that Liu Qingshan successfully solved three biological warships in alien aliens. Yes, before that, that kind of biological battleship looked almost invincible. Because of their own anti-aircraft firepower, for them, there is almost no effect at all. A very typical example of this is a dozen or so Menniu Dog combat vehicles, which are all their own professional-level air defense combat forces. However, it was the more than a dozen men bull dog combat vehicles that had professional air defense capabilities that attacked at the same time, and they attacked continuously for a long time, but they were not able to shoot down the next satellite alien biological warship.

It can also be seen from this point that the kind of alien alien biological warship is indeed indeed a natural immunity to Liu Qingshan's anti-aircraft firepower at one time. However, this did not last long. Not long after, by chance, Liu Qingshan had an idea, and finally raised his own science and technology center, (that is, the firepower increase button in the science and technology center) to take over, and the air defense capability of his mammoth tank and the Door Bulldog combat vehicle has been extremely significantly improved.

For Liu Qingshan, his own economic operation system, even more important than some military facilities such as war factories, science and technology centers, and so on. Because, indeed, that's really the foundation of a base. And in terms of alien aliens, it seems that this is also very clear. Therefore, the destruction of Liu Qingshan's economic system has been intensified more and more. They are well aware that it is better to spend more money and consume more combat power to destroy the opponent's combat units and military strength, and it is better to directly destroy the opponent's economic system.

－－－－－－－－－－－－－－－－－－－－－－－－－－

Liu Qingshan admitted that the opponent's combat method was very vicious, and it could even be said that it really hit his own vital point. Therefore, when he came back to his senses and eased up, the first thing he had to deal with was the biological warship combat force that had destroyed his own mining vehicles.

At this time, Liu Qingshan saw that his improvised air defense combat team had rushed to the bottom of the several biological warships with satellite aliens. At this time, those satellite alien warships were still sending out dense biological carrier-based aircraft one after another, continuing to frantically pursue their remaining mining vehicles. At the same time, while pursuing, while attacking, the crazy laser beam, very dense, and falling from the sky, carrying one after another terrifying breath, evil breath, bloodthirsty breath, ruinous breath.

Finally, the decored enemy of a mining cart could no longer strike so violently, facing the laser beam attacking from all directions, and soon after, it exploded with a bang. And after seeing this scene, Liu Qingshan's heart couldn't help but tighten. He knew that this was the fourth mining truck he had destroyed by the other party.

"Attack now!" In this way, with Liu Qingshan's order, the first to attack was the three men cattle dog chariots that were damaged by Yan Zòng. is the so-called shame and courage.

It should be said that those three Menniu dog chariots, before that, as the only air defense needle and thread flying in Liu Qingshan's military base, had been ravaged by the madness of this kind of biological warship in terms of satellite aliens. At that time, the science and technology center in Liu Qingshan's military base had not yet upgraded its firepower attack, so more than a dozen Men Niu Dog chariots, in the eyes of the other party, were simply a bunch of waste. However, the other party's biological carrier-based aircraft showed no mercy, and at one time, on the ground, those Door Cow Dog Chariots continued to explode, destroy, die, and disappear one after another.

That's really the case. In many cases, in many situations, there is a kind of sadness that sits helplessly. That is, the other party can attack himself frantically, but on his own side, in the face of the other party's crazy attack, so crazy killing, so crazy to kill the killer, but. Powerless. Because of the attack on his own side, for the other party, it is simply an itch in the boots, and it will not help.

Finally, under such circumstances, the air defense combat unit that Liu Qingshan had just set up finally displayed a very good combat capability, and one after another air defense missiles burst out of the air and hit the target fiercely. So, in mid-air, in the midst of lightning and thunder, one after another anti-aircraft missiles hit the target.

This time, Liu Qingshan saw that after each air defense missile hit the target, it emitted a deafening explosion with a booming bang. Moreover, with the rumbling explosion, it continued to come out, and purple-red light continued to shine. It can be seen that the explosive power and lethality of this anti-aircraft missile launched by the Menniu Dog Chariot are at least ten times higher than that of the science and technology center not long ago, when it was not upgraded.

Due to the speed of the mammoth tank, it lagged far behind the speed of the Dog. Therefore, after the three Men Niu Dog chariots attacked with all their might for a period of time, the five Mammoth tanks finally rushed over. So, the three mammoth tanks began to fire flare-like anti-aircraft missiles. This kind of anti-aircraft missile is very different from the anti-aircraft missile launched by the Menniu dog combat vehicle. In terms of flight speed, it is far slower than the flight speed of the anti-aircraft missile of the Men Niu Dog combat vehicle. However, despite this, once this missile hits the target, it shows extremely powerful and terrifying lethality.

Yes, it is. This can be seen from the lightning explosion that looks like lightning at first glance after the missile hits the target.

In this way, in the face of Liu Qingshan's mammoth tanks, and the anti-aircraft missiles with extremely powerful attack power that were fired out, in mid-air, those alien alien biological warships, finally, could no longer contain such a fierce attack, and fell down one after another, and they all exploded.

Facing this scene, even Liu Qingshan felt a little incredible. Yes, just now, seeing that his own side was completely on the verge of collapse, but at the critical moment, the fire upgrade button in that science and technology center finally changed this qiē. Although, in order to use that one firepower upgrade button, almost completely used all the production and construction funds in Liu Qingshan's hands, for Liu Qingshan, this is very much. Because, after spending more than 100,000 yuan in production and construction funds, the combat performance of almost all of Liu Qingshan's combat units has been greatly improved. Otherwise, it would have been impossible to shoot down those air biological warships with satellite alien avenues so lightly.

－－－－－－－－－－－－－－－－－－－－－－－－

Under such circumstances, finally, Liu Qingshan knew that his military base had finally survived a crisis. However, despite this, thinking about it now, Liu Qingshan still feels very afraid. Yes, if I hadn't been able to upgrade that technology center in time at that time, then, most likely, my base would have been in ruins long ago.

However, although he has now spent this pursuit in Zhongshan City, Liu Qingshan knows that in terms of alien aliens, he will definitely not give up with him. And, over time, the other side may resort to more brutal means. Therefore, in the next time, for Liu Qingshan, the most important thing is still to strengthen the construction of his own base and enhance his strength. In particular, the construction of its own airfields should be further accelerated.

What is certain is that although now, Liu Qingshantong has upgraded his science and technology center and significantly improved his attack ability, but even so, in terms of alien aliens, he will definitely take corresponding countermeasures. Not to mention anything else, as long as they can further strengthen and defend their defense capabilities on their air biological warfare ships, in this way, Liu Qingshan's air defense firepower will definitely be greatly reduced.

Moreover, for those satellite aliens, Liu Qingshan knew that the most fundamental way to deal with them was to destroy their military bases, even the base camp nests. Uproot, leaving no hidden dangers. Only in this way, on this Teslam planet, can it be regarded as a real foothold.

Although the evil alliance has not been completely eradicated, Liu Qingshan knows that because the evil alliance has been greatly damaged, in this way, in seventy years, the appointment will no longer form a climate. Therefore, as long as he can wipe out the alien strength of these satellites, then the unification of this Teslam planet is already just around the corner.

Therefore, after finally losing this fierce attack of the alien aliens, next, Liu Qingshan plans to use his own ore collection system first. Because some time ago, he destroyed a lot of alien aliens in his mining arms. Therefore, Liu Qingshan decided that, on the one hand, at least five Tyberon mining vehicles should be produced, but the mining vehicles are shouldering the burden of the economic development of their entire base. Therefore, there must be no shortage of them. For this, Liu Qingshan's heart is very clear.

In addition, Liu Qingshan will make a heavy decision, that is, to once again float a Tybron ore refining plant. Because so far, after such a long period of ore gathering, the military base located in its own serves as a Tiberon ore warehouse, and the Tiberon ore resources on it have been almost collected.

In this case, it is no longer enough to rely on the Tiberon mine located on the site. Therefore, Liu Qingshan was not worth his attention, and transferred to the comfort of his own military base. To the southeast, about thirty kilometers from his military base, there is a blue deposit of high-energy Tiberon. Liu Qingshan knew that the energy contained in the Boneng Tabran ore was twice that of the average Taberyn ore resource. It's just that the Tiberon mine is too far away from its base, so the mining trucks will take too long and travel too long before they travel back and forth between a mine and their own military base, so the mining efficiency will be very low. In this case, the only way to do this is to build a new ore refinery directly in the blue Tibron deposit. In this way, the problem of inefficient ore gathering can be solved.

Although the rebuilding of a Tabyron ore refining power plant must consume a certain amount of production and construction funds, it is very worthwhile for Liu Qingshan. Because, as long as a brand new Tyberon ore refinery is built there, then the school will be rich and profitable, because the efficient ore collection will create a high profit for itself. It's worth a profitable deal, in this case, where would Liu Qingshan miss it?
