Faced with this kind of crisis, Liu Qingshan naturally did not dare to be careless. However, now, his ground attack force is basically all concentrated at the entrance and exit of that canyon, and when Liu Qingshan and Jia all the siege cannons in and out of the entrance and exit are mobilized, they are helpless to see that there are only seven to eight of their ten laborers left so far.

And the combat units of the enemy army that attacked them are now all gone. Xiao Yiming cried and reported to himself the entire process of being attacked by enemy troops.

Liu Qingshan now realizes very clearly that now, he really can't, just passively being beaten, but should take the initiative to attack. Because, under the current situation, Liu Qingshan has realized that the enemy army has continuously expanded its forces to his side. If this continues, then, it is certain that the space for oneself to turn around will become smaller and smaller.

Liu Qingshan felt that it seemed that before this, he was too conservative. Therefore, it led to the current situation. After all, now, in their own hands, a considerable amount of combat power is already in their hands. At the very least, although with these combat forces, the time is not yet ripe for an all-out counterattack on the enemy's bases. However, it is still possible to engage in a few battles with the enemy army in a place not very far from your base camp, and in this way, you can broaden your range of activities and protect your minimum interests.

－－－－－－－－－－－－－－－－－－－－

So, after thinking of this, Liu Qingshan decided that next, he should look for an opportunity to give the enemy a battle. Otherwise, staying in your own base will send a message to the enemy that you are too weak to be bullied. This situation, for Liu Qingshan, is absolutely not allowed. Yes, it is.

As a result, Liu Qingshan became big and commanded the Viking fighter flight formation, an air flight formation that he had just formed, and set off from his base camp to patrol and fly around his base. Liu Qingshan knew that in this way, on the one hand, he could further ensure the safety of his base, and on the other hand, in this case, he could also discover some movements of the enemy army in time. Therefore, according to the movements of these enemy forces, the side will formulate the next course of action.

Not long after, Liu Qingshan finally discovered that not very far from his base camp, it seemed that there were other creatures carrying out activities. And, there, there are plenty of shadows, and it seems that some buildings have been built. Damn, damn it, what the hell is going on? After seeing this, Liu Qingshan's first reaction was that the enemy army had already built their forward positions there? Or is that a place originally had a certain amount of ore resources, so the enemy army, on the one hand, built their ore gathering facilities there, and on the other hand, took this opportunity to meet their forward positions there, or their outposts?

Liu Qingshan thought about it again and again, and finally, finally recognized his guess. It seems that this possibility is still very large.

So, after thinking of this, Liu Qingshan gave an order, and then the flight formation composed of his Viking fighter quickly flew over the symbolic target. And as his Viking fighter flight formation flew quickly towards the target, the fog of war was constantly being pulled away, and in this case, Liu Qingshan actually had a feeling that Liu Zheng had seen the sun. Yes, in the process of flying at high speed of his Viking fighters, as the fog of war was constantly pulled away, the ground, lofty mountains, and the vast and boundless wasteland were completely presented in front of Liu Qingshan.

Of course, at this time, in this situation, Liu Qingshan was not in the mood to enjoy the unique scenery above Tesla's planet. He had to shoot out what was going on in front of him in the shortest possible time. However, if your guess is correct, then the enemy will determine where to build their outpost. At the same time, it also serves as one of the energy harvesting plants for ore and functional gas collection. However, for this situation, Liu Qingshan will never allow it to happen. Compare, here, the distance to their own base camp base is exhausted. Under his nose, he actually mined resources and built outposts, damn it, this is too much of a thing.

Sure enough, not long after, Liu Qingshan led his Viking fighter flight formation and finally arrived in that area. As the fog of war was pulled away, Liu Qingshan finally saw that there, the enemy army had indeed built their ore collection facilities. In addition, Liu Qingshan also saw that a number of enemy laborers were building bombing other military facilities one after another. It seems that, as I had guessed, the enemy really planned to build their outpost here.

After seeing this situation, Liu Qingshan couldn't help but be furious. So, at the sound of an order, the seven or eight engineering tanks of his own, which had been defending at the entrance and exit of that canyon, marched along the long, narrow canyon that seemed to be very advantageous, towards here. In the reconnaissance just now, Liu Qingshan had already seen that here, although the enemy army had built some ore gathering facilities, there was no relatively strong defensive combat force. At best, two or three engineering tanks. On his own side, he has seven to eight siege tanks.

In terms of air combat strength, it has an absolute advantage. Only Viking fighters, at present, have produced as many as thirteen. Therefore, in this case, Liu Qingshan has absolute certainty to win this battle. Finally, after three minutes of scenes, some of their engineering tanks finally approached the area that had been occupied by the enemy. Here, it seems, the terrain is very treacherous, and it is really easy to defend and difficult to attack. However, despite this, since Liu Qingshan has made up her mind, then, no matter what, she must also take back this area.

From that canyon to the mine that had been occupied by enemy troops, there was a slope. Now, Liu Qingshan's dozen or so heavy tanks are slowly crawling towards the ore base from below. Of course, in this case, they will be slow to do it often. And while they were writing, in the mines above, basically in the center, the three enemy siege cannons had naturally discovered their targets and had begun to bombard.

Tom tom, tom tom, Liu Qingshan's ears, at this time, there was clearly a deafening sound of cannonball. Liu Qingshan knew that this kind of siege cannon had a very large aperture, and the shells fired out of it, on the one hand, had a very long range, and at the same time, the lethality was even more powerful.

In this way, as the sound of intense shelling continued to sound, a floating siege tank that was still climbing Liu Qingshan, who was rushing to the front, suddenly exploded after several heavy shells fell on top of his head in a row, almost at the same time, with those heavy shells, it exploded, but a tank of Liu Qingshan also exploded.

However, at this time, the other engineering tanks behind had all climbed up. So, with Liu Qingshan's order, all the engineering tanks switched to the siege state. In this way, their range will be further increased, and their attack ability will naturally be increased a lot. So, all of a sudden, the cannon fire was continuous, the cannon rumbled, and then again, and that piece was immediately dyed by the fiery red explosion light, and it was a gorgeous and colorful scene.

Now, after a great battle, Liu Qingshan finally occupied the area in the center that the enemy intended to use for the construction of an outpost. Liu Qingshan knows that the geographical location of an area is very important. Basically, it's between the bases of both the enemy and the enemy. This is one of the main reasons why, on the part of the enemy, always have to find a way to see the outpost there.

At the same time, there are quite rich crystal ore resources, in addition, there are two functional gas injection shafts. Under such circumstances, Liu Qingshan decided to simply transfer his control center here. Because, in this way, some of their own labor machines can also maximize their collection efficiency. Otherwise, even if you can collect the mineral resources and functional gas blown by the wind here, it will take too much time to return to your base camp from here.

So, with Liu Qingshan's order, I saw that in his own base camp, the control center of his own was slowly soaring. Yes, underneath him, there was a fierce spray of orange-red tail flames, and it was precisely by relying on the extremely powerful counter-thrust of these orange tail flames that this self-controlling center could be lifted into the air.

Then, Liu Qingshan sent three more Viking fighters to open the way in front. Because, once you encounter the enemy's air strike force, then you don't have any attack ability to control this center of your own. Therefore, it is naturally very necessary to send a few Viking fighters to escort it. Of course, Liu Qingshan is very clear about this point. Yes, it is.

Sure enough, in the process of flying, Liu Qingshan saw that because of his own control center, after all, the volume was too large and the weight was too heavy, so its flight speed was naturally not very fast. Although the rear tail is sprayed with a thick orange tail flame, it is naturally unable to increase its flight speed.

Suddenly, Liu Qingshan found that two enemy Iron Crow fighters were actually gathering here. And the Iron Crow fighter, its flight speed, no matter what, is faster than the flight speed of its own control center. Moreover, now, Liu Qingshan already knows that this kind of Iron Crow fighter, as a high-end air combat force, cannot be underestimated. Although she does not belong to the professional level of air strike units, her attack methods are indeed very sophisticated.

Yes, it is. First of all, of course Liu Qingshan knows, that is, this kind of Iron Raven fighter can launch a missile. This kind of missile itself is equipped with a very sophisticated guidance system, and once the target is locked, then it is absolutely not a purpose. However, it did not exist for a very long time. Within the time of his effective attack, it can be judged that he will continue to pursue his target.

In addition, there is also a very important point, that is, this Iron Raven fighter can also constantly fire a small combat weapon against the enemy with an automatic machine cannon. This kind of automatic machine gun can be continuously projected to the Iron Jaw fighter plane, and then, it can be used for both attack and air attack. Although it has not been stored for a long time, it is precisely because of its low cost and can be deployed at any time, so it does have extremely powerful attack power.

In addition, this Iron Jay fighter can also release a small combat weapon with very good defensive performance, called an automatic defense target aircraft. This kind of automatic defense target aircraft can continuously shoot out one defense laser beam after another, and these laser beams can intercept most of the missiles, so as to ensure the safety of their relevant combat units to the greatest extent.

This is because Liu Qingshan already has a very deep understanding of this kind of Iron Crow fighter, so at this time, when he was in the center of his own plane, starting from his base camp, and flying towards the place that had just been occupied by him and had very rich mineral resources, he was actually targeted by the enemy's two Iron Crow fighters in mid-air. Liu Qingshan knew that at this time, if this kind of enemy Tianyi fighter launched an attack from his young control center, he could only rely on that kind of missile attack. Sure enough, just when the enemy's two Iron Raven fighters were still more than 30 kilometers away from the center of their own plane, the attack had already begun. I saw that suddenly, with a strange sound came, from one of the enemy's Iron Crow fighters, a missile was fired, this missile, it seems, is constantly shining with white light, although its flight speed is not very fast, but, indeed, it is really traveling with it, and it has actively locked on its own control center.

In this process, although Liu Qingshan commanded one of his own control centers and constantly changed the direction of flight, the two missiles behind him, which were fired by the enemy's Iron Crow fighters, also constantly changed direction and finally hit the target.

Coaxing, coaxing, although the attack effect is not very obvious, however, it also knocked out about 30% of his health in the center of the control. It can be seen that this kind of Iron Raven fighter really has very good combat performance. It was also at this time, in this situation, that it was certain that Liu Qingshan was even more impressed by this kind of Iron Crow fighter.

Fortunately, before this, Liu Qingshan had already sent two of his own Viking fighters to escort the country. At this time, the two lines of Viking fighters had already turned around and attacked the enemy's two Iron Raven fighters from the left and right directions.

Tom tom, tom tom, continuous artillery fire, burst out, the dense anti-air attack firepower, but it belongs to the professional level of anti-air attack force. After receiving such a fierce attack, the two Iron Raven fighters of the enemy turned around and prepared to flee. However, with that flight speed, they were naturally far inferior to Liu Qingshan's Viking fighters. I saw that at this time, the two Viking fighters, while attacking, followed closely and bit on.

In the end, under the relentless pursuit of Liu Qingshan's two Viking fighters, in their continuous attacks, in the end, the two enemy Iron Crow fighters were finally destroyed.

Next, not long after, two Viking fighters finally escorted Liu Qingshan's control center, and landed in that place rich in mineral resources. At this point, Liu Qingshan knew that it could be said that he had occupied a place of great strategic value. In this way, it means that he has basically occupied the initiative on the battlefield. In the next step, Liu Qingshan knew that the time for his own big counteroffensive had finally come.

―――――――――――――――――

Now that he has occupied a place with quite good combat power significance, then, naturally, for the improvement of Liu Qingshan's combat power, as well as the speed of base construction, etc., it is naturally of very good significance.

At the same time, in the process just now, Liu Qingshan had really seen the outstanding performance of that kind of "Iron Crow Fighter". Yes, even Liu Qingshan even thought that if he could have a sufficient number of Iron Crow fighters, then he would be completely able to rely on these numbers of Iron Crow fighters to cross the world and dominate the Eight Wilderness! Yes, that's how it is. After all, that thing, with its combat performance, is really too strong!

Now, in order to be able to produce a sufficient number of Iron Crow fighters, Liu Qingshan simply shifted the upgrade mode of his star port from the direction of the "real room" to the direction of the "reactor". In this way, you can spend the same production and construction money, but you can produce two identical combat units! In this way, in the near future, Liu Qingshan will also have a large number of Iron Crow fighters.
