In this way, in the following period of time, Liu Qingshan finally built two airfields, and on each airfield, four Fire Eagle fighters were stationed. Liu Qingshan knew that this kind of Fire Eagle fighter has an extremely powerful ground-to-ground and ground-to-air attack capability, and it is indeed a very good air combat force.

In this way, he will be able to deal with those air biological warships on the enemy side. And before that, although the technology center was upgraded, Liu Qingshan's horn combat unit had greatly improved its attack firepower, and at the same time, it had also been able to deal with the enemy's air biological warships on a certain level. However, as time goes on, the alien alien side will definitely be working on countermeasures. Therefore, this problem must be solved from the root.

Now, Liu Qingshan has basically realized that as long as he can deal with the air warships of the alien aliens, then, it should be said, the other party will not pose much of a threat to him. However, it is absolutely impossible to do this with only those ground combat units of its own. Yes, it is.

The reason is very simple, although he has upgraded the science and technology center by himself, improved his attack capabilities, especially anti-aircraft firepower, and has developed rapidly. However, then again, those satellite aliens also have very advanced science and technology. In the military field, it is very advanced. In this case, it is very likely that the other side will be able to strengthen their defensive combat performance at any time.

－－－－－－－－－－－－－－－－－－－－－－－－

Therefore, it is precisely with this reason in mind that Liu Qingshan decided that it is necessary to produce the necessary air combat force to deal with the enemy's kind of air biological warships. Of course, due to his own air combat unit, only this Fire Eagle fighter is the most powerful, so the Fire Eagle fighter has naturally become Liu Qingshan's first choice. Now, the two airfields and eight Fire Eagle fighters have been controlled by Liu Qingshan. As long as Liu Qingshan gives an order, then these eight Fire Eagle fighters can take off at any time and perform their duties.

However, for a period of time, the follow-up alien alien side, in the battle just now, was damaged Yan zhòng, after all, more than a dozen biological warships were destroyed at once, which was also a heavy blow to them. Therefore, for a period of time, the alien alien has finally relaxed its attack on Liu Qingshan's military base. Therefore, this period of time has also become a very rare and precious calm.

However, not long after, Liu Qingshan ordered the 8 Fire Eagle fighters to fly into the air one after another, and then deploy them separately in the direction that the alien alien side might attack. Looking at the 8 Fire Eagle fighters, in mid-air, in their own military bases, constantly flying and patrolling, Liu Qingshan's heart was a little more stable. Yes, since then, even if the alien alien side once again sends the alien alien warship in the air, then, with the excellent aerial interception ability of these 8 Fire Eagle fighters, it should not be a big problem to eat them all and intercept them.

Because, with the upgrade of its own science and technology center, the offensive firepower has been significantly strengthened, not only the tank combat units, but also the fire weapons belonging to all the fighters have also been significantly improved. Therefore, in this case, their own Fire Eagle fighters, which have very good air defense combat capabilities, will be further strengthened.

In this way, the eight Fire Eagle fighters have been constantly defending against the air attack forces of the enemy that may come on, and naturally they have added a safety lock to the safety of their own military base.

However, at the same time, Liu Qingshan also made a bold decision, that is, to turn defense into offense. The reason why Liu Qingshan took this into account was mainly because he knew that in the battle not long ago, although, at the beginning, a large number of combat forces were also dispatched. However, with the passage of time, especially when one's own technology center upgraded its attack firepower, it naturally completely salted the opponent's attack firepower at once.

In this way, in terms of alien aliens, the original attack is actually fierce, and it seems to be weak. In particular, when the opponent's dozen or so aerial biological warships were finally destroyed, the situation on the battlefield suddenly came to a big reversal. It was really turned upside down, and in the end, with the scrapping of all the dozen or so air biological warships on the alien alien side, it should be said that, basically, this attack on the enemy side ended in failure.

At the same time, Liu Qingshan realized that since the other party was damaged and there was a shortage of troops, this was also a very good opportunity for him to fight back. Although, in this case, in his own hands, there is not much combat power. Yes, it is. Above their own forward positions, there were only seven Mammoth tanks. However, they have all been upgraded to the one-star level. The combat capability is still very good.

In addition, in his own military base, Liu Qingshan has only produced seven Marauder tanks so far. Because some time ago, because he had invested almost all of the production and construction funds in upgrading the science and technology center, in this case, Liu Qingshan knew that he should temporarily give up the production of that kind of mammoth tank. After all, the mammoth tank was too expensive to build and the production was too slow. In this way, it is not conducive to the conduct of this battle.

Because, on the one hand, it is not yet known exactly when it will attack his outpost positions again. Once you are caught off guard by the other party again, then you really lose more than you lose. Therefore, it was under this circumstance, with the production and construction funds in hand already very limited, that Liu Qingshan decided to produce seven or even a dozen Marauder tanks to temporarily enhance his combat strength.

Relying only on these combat forces, can we launch an attack on the enemy's military bases? Relatively speaking, Liu Qingshan knows that this requires courage and strategic vision. If we look at our current strength alone, it should be said that after such a long period of fighting, the troops are in great need of further rest. However, having said that, over time, it is quite possible that the result of the guide zhì is that it will also be further improved after a certain amount of time. Moreover, the rate of improvement of the combat forces of the localities, most likely, is much higher than their own.

Then, since this is the case, Liu Qingshan decided to simply do nothing, and for the time being, he will use some combat forces in his hands to immediately launch a small-scale attack on the military base in terms of satellite aliens.

Liu Qingshan knew that for himself, this attack might just be simulated, just tentatively, or a real sword, but for Liu Qingshan, this qiē seemed to be indifferent. Now, the five Marauder tanks that had just been produced crossed the stone bridge at great speed, and came to the north side of the stone bridge. Where was Liu Qingshan first, he first saw the former light wave cannon array that had become a pile of ruins.

Yes, in the current situation, once again I saw a large array of light wave cannons that had made great contributions to consolidate my body, and now, it has actually become a ruin. It looks mottled and disjointed, and it seems that you can't see anything.

In front, there is a power plant on the side of the enemy. Under such circumstances, Liu Qingshan decided to simply start this power plant without doing anything. So, after thinking of this, with Liu Qingshan's order, he self-inspected the five Marauder tanks that rushed to the front to launch an attack. Since this was before, Liu Qingshan had just successfully upgraded his weapon attack system, so when the seven Marauder tanks opened fire, one after another dazzling bursts of fire burst out of the air, and shot at the target one after another with a fierce and terrifying aura. In this case, what made Liu Qingshan feel very satisfied was that in this way, not only did he show it, but when he attacked, the effect was very good. Moreover, even under normal circumstances, this is not possible.

－－－－－－－－－－－－－－－－－－－－－－－－－－

The actual situation, just as Liu Qingshan considered, is actually now, in terms of satellite aliens, the strength is indeed very tight. Or rather, those alien creatures are ready to stand up for such a large-scale attack. It's just that the combat strength in their hands is not very sufficient at present. In this case, they had to postpone the time of the attack.

However, they didn't expect that at this time, Liu Qingshan had already sounded the horn of attack to them. Five Mammoth tanks, seven Marauder tanks, mighty and imposing, have now rushed to the military positional units on the alien alien side. There, a defensive turret was carrying out a fierce attack on Liu Qingshan's combat forces that had already attacked. However, compared to Liu Qingshan's combat unit, the defensive turret was insignificant. Soon after, the piece was destroyed.

However, at this time, the alien alien side has realized that it seems that if there is no real advantageous combat force, it is very likely that it will be more passive. So, with the order of the general Silda, the five biological warships once again flew into the air. It should be said that for this alien alien creature, this biological warship can be said to be the most powerful combat force. Then, roaring, towards Liu Qingshan's attacking combat unit, he attacked directly.

After seeing this, Liu Qingshan couldn't help but smile coldly. Yes, for the other party may take this move, in fact, Liu Qingshan has long expected it. Yes, it is. At this time, the eight Fire Eagle fighters were circling and cruising in their own military position units. At that time, the reason why Liu Qingshan deployed those eight Fire Eagle fighters there was, on the one hand, to defend against the enemy's possible air attack force. On the other hand, it is also considered that in this way, you can attack the opponent at any time. In particular, when their own ground combat forces encounter the kind of air warships in the alien aspect at one time, these Fire Eagle fighters can provide fire support at any time.

Now, the development of the situation, sure enough, has come to that point. Under such circumstances, Liu Qingshan gave an order, and the eight Fire Eagle fighters immediately flew over the river and the stone bridge, and then, straight towards the enemy's air biological warships, the tiger roared and flew over. At this time, a fierce air-to-ground battle was going on between the two sides.

Because Liu Qingshan's mammoth tank itself has a very good air defense combat capability, at this time, one after another air defense attack beams shot out, broke through the air, pierced the space, and shot straight at the top of the ~~ target. However, just as Liu Qingshan expected, the opponent's biological warships, now, their armor has also been improved, thus greatly improving their defensive performance. Therefore, in this case, although Liu Qingshan's mammoth tank, the combat capability has been significantly improved, especially the combat strength of the air defense drum, since Liu Qingshan successfully upgraded to his own science and technology center, the air defense performance has increased at least tenfold.

However, despite this, the opponent's air biological warships seem to have been greatly improved in terms of defense capabilities. Therefore, the current air defense attack is actually not so effective. However, in mid-air, the countless biological carrier-based aircraft once again launched a powerful attack. This kind of attack is very terrifying, and those biological carrier-based aircraft themselves carry an extremely terrifying and murderous aura, bloodthirsty and crazy, brutal and ferocious. At this time, because they were also improved again not long ago, their defense performance was constantly improved, and the offensive type was also enhanced.

I saw that from mid-air, dozens of satellite alien-shaped biological carrier-based aircraft spewed out flames one after another, and those flames were cyan, shining in the night sky, looking extremely bright. For a while, the two sides went back and forth, and the attacks continued. Of course, in this case, it is normal for each other to have casualties. However, just when the battle between the two sides was intractable, Liu Qingshan's Fire Eagle fighter finally flew over.

The 8 Fire Eagle fighters were divided into two directions, from the left and right directions, towards the remaining biological warships of the alien alien formation. Immediately afterwards, I saw that just after gradually approaching the target, the gray-white attack beam that activated the eyes was like a long sword, extremely powerful, and the momentum was soaring, and the killing aura was undoubtedly revealed. Moreover, this time, Liu Qingshan adopted the operational policy of concentrating troops, concentrating firepower, and breaking through each other. In this case, the left and right sides went to those Fire Eagle fighters, and each pointed all the attack forces at one of the targets. At the same time, on the ground, Liu Qingshan's mammoth tanks and the Dose Gate Bulldog chariot that came over later were also put into battle again.

In this way, the battle was extremely fierce for a while. Finally, half an hour later, Liu Qingshan finally discovered that his Fire Eagle fighter was indeed a very good lethal ship for those alien alien creatures in the air. In the end, although there was only one of the 8 Fire Eagle fighters left, and the only Fire Eagle fighter this time was also damaged in the battle just now, so the rear tail dragged billowing black smoke, and the health value was only about 30%.

However, the final result was the complete elimination of the alien alien aerial biological warship combat force. In this way, it should be said that Liu Qingshan's ground attack combat unit has finally lost the threat from the air, and naturally can continue to attack again. At this time, the opponent's military base is relatively empty, and it is the best time to attack with all its might. Since this is the case, Liu Qingshan will naturally not miss it. So, with Liu Qingshan's order, the ground offensive began again.

In this case, General Silda, the former commander-in-chief of the alien aliens, had a hideous face and looked very annoyed. He didn't expect that his once invincible biological combat force was now facing such a formidable opponent. Moreover, not long ago, the other party's military base was about to be destroyed by itself. Alas, in the blink of an eye, the situation has reversed. The other party actually arrived at his doorstep. It's incredible.

What's more, what's even more strict is that the air biological warship that he used to be proud of is now actually talking about the opponent. It seems that the other party's air fighter is not simple. Moreover, even from the point of view of our country's Cheng Dù, this kind of biological warship given to me is evenly matched, or even evenly divided. In this way, it should be said that the combat power in one's own hands is no longer enough to threaten the other side's survival. In this case, then, you should think of a way. Now, however, the opponent's attack, the ground attack, seems to be increasing unabated, and the momentum is huge. In this case, the only thing he can do is to go all out and pull up all the combat forces of alien creatures in his military base. Only in this way, there may be a glimmer of life.
