In this way, the three alien alien air warships really flew towards Liu Qingshan's defensive position again!

And at this time, in the alien alien headquarters, the commander-in-chief, General Chelsea, frowned, clenched his teeth, and said viciously: "Hmph, Fire Eagle Fighter, Fire Eagle Fighter!" Damn, no matter how powerful you are, but there are times when you run out of ammunition! I'll see what you can do with the ammo after you've run out of ammunition! Isn't it just to go back and reload ammunition? And now, for Lao Tzu, it is a very good opportunity, a very good opportunity! ”

Yes, General Chelsea, he is still very confident in his air warships. Yes, it is. This is true whether it is its own destroyer battleship or that kind of alien mothership. General Chelsea is convinced that as long as his three remaining air warships, once they approach the core of the opponent's outpost base, with their incomparably powerful air-to-ground attack capabilities, they will kill the only remaining building factory in the opponent's outpost base, then this outpost base will basically be finished!

And once this outpost base is destroyed by himself, then things will be much easier. Yes, it is. At the very least, in a short period of time, it is impossible for that "ironclad god of war" to build a new and other outpost base at his "doorstep" so quickly. Yes, that's for sure.

It should be said that General Chelsea was still very satisfied with the lethal effect caused by his superweapon, the Space-Time Rift Destroying Miè Armor attack just now. That attack directly wiped out the opponent's outpost base, which was in the process of continuous improvement, including a tank factory, a recruit training camp, and two airfields! There is only one construction plant, one ore refinery, and another airfield!

He believed that with his two aerial warships finally reaching the core of the opponent's defense base, with their extremely powerful attack capabilities, it would be very simple to directly kill them on the basis of the superweapon attack not long ago.

Therefore, when General Chelsea saw Liu Qingshan's three Fire Eagle fighters and finally flew away, he concluded that they were going to reload ammunition. And this is undoubtedly a very good opportunity. So, he gave an order and ordered his remaining three air warships to accelerate towards Liu Qingshan's outpost base and rush towards it.

However, he General Chelsea did not notice that five or six anti-aircraft guns were being built on the ground. Yes, it's no wonder that that kind of anti-aircraft gun looks very inconspicuous, it's like a dirt bun, it's rustic, and it's hard to find it at all. And in this case, it is normal for Chelsea not to attract attention.

However, just as the three air warships on the alien side were approaching the edge of Liu Qingshan's outpost base, all of a sudden, from the ground, one after another on the earth-colored "mounds", they continued to shoot into the sky, bursting into the sky! Yes, the frequency of those anti-aircraft fires was so high that it was almost unparalleled, and it had even been intertwined into a network, like fireworks rising into the sky, whistling, breaking through the air, and attacking the target fiercely!

―――――――――――――――――――――――――――

And for the three alien alien air warships, they couldn't help but be stunned in the face of the sudden attack of anti-aircraft fire from above the ground. Yes, such an air raid is indeed too fucking sudden! How did it start so suddenly without warning!

"Didn't the commander-in-chief detect the presence of anti-aircraft artillery fire here? And the whole thing is constantly monitored! But doesn't that make us all jump into the fire pit with a glare? One of the alien pilots said dissatisfied.

However, now, since they have sunk into it, it is useless to sigh, only try to concentrate all the firepower and kill those few anti-aircraft guns! So, suddenly, the rain of the ground attack beam shot down to the ground like raindrops, and then a series of violent explosions erupted one after another, sounding deafening and endless.

Although, those three alien alien air warships caused a certain amount of lethality to the air defense guns on Liu Qingshan's ground, but, then again, after all, those air defense guns, that are professional-level air defense forces, that kind of high-frequency air defense fire attack, for the ghost-like alien alien warships in mid-air, it is even more fatal!

So, for a while, the battleship of the destroyer at the front of "Boom Boom~~~" was shot down as a matter of course, and from that mid-air, it suddenly lost its balance, and then, it began to roll, circle, roll, fall from the sky, and then hit the ground, blowing up countless wreckage and fragments, scattering in all directions!

―――――――――――――――――――――――――――

"It seems that it is really impossible for me to build another outpost of my own here without occupying the Tiberon mine opposite the Great Rift Valley!" Liu Qingshan couldn't help but think to himself.

Since this is the case, then, simply, Lao Tzu fought with them!

At this time, Liu Qingshan had already produced more than a dozen mammoth tanks. However, it is a pity that this kind of mammoth tank, although its comprehensive combat capability is very good, is not able to call an air vehicle, that is, that kind of large air transport aircraft. In this way, their mobility and agility have naturally been greatly affected. And in many cases, in many cases, the mobility and flexibility of a unit are, indeed, an important factor in judging their comprehensive combat performance.

Therefore, although Liu Qingshan knew that his kind of mammoth tank was indeed a rare unit with multiple combat capabilities, because it did not have the ability to roar large air transport vehicles, it was decided that they did not have the power to go to that rift valley and carry out tasks at all.

Since this is the case, then, simply, if you don't do two rests, Lao Tzu will use that kind of regional armored troops. Well, just use them! Liu Qingshan couldn't help but think fiercely. Yes, the regional armored corps, not long ago, used this kind of regional armored corps as a striker, and as a result, it was once brilliant.

However, this kind of regional armored forces do not have the ability to fight air defense. And now, the alien alien side seems to pay special attention to that kind of air strike, and in this case, if there is no air power, how can it be done! That's not exactly a live target for alien attacks!

"Take the regional armored corps as the main force, and then, with the appropriate air defense!" Liu Qingshan thought to himself.

Although now, there is no longer a mobile air defense force in Liu Qingshan's outpost base, but at this critical time, Liu Qingshan has already decided to simply use more than a dozen Men Niu Dog chariots from the nearby outpost base as his own air defense firepower.

However, now, in Liu Qingshan's hands, there are only six or seven regional armored soldiers. And his own boot camp, that is, not long ago, has been directly wiped out by the superweapon bombardment of the alien alien. Therefore, in such a situation, he simply does not do anything, and he will first borrow two or three regional armored soldiers from the outpost position of his own friend, which will be enough to really occupy a strategic place on the other side of the Great Rift Valley, gain a firm foothold there, build his own outpost base, build an ore refinery there, collect ore resources, and convert them into more production and construction funds......

So, for a while, with Liu Qingshan's order, from a nearby outpost base, seven Menniu dog chariots and fifteen regional armored soldiers, all of them flew straight towards the front line of the battle on a large air transport plane. But even if it's the nearest outpost base, then again, so what? Anyway, it will take at least a three-day flight!

With the help of this opportunity, Liu Qingshan commanded the mining vehicles under his command that had already arrived in the process of ore quarrying, and continued to collect ore. Yes, it is. Although, now, Liu Qingshan also knows, that is, there is not much Tabyron ore on the Tiberon deposit in his outpost base.

Therefore, sending troops to the opposite side of the Great Rift Valley to occupy the Tiberon mining area there has become the only way out for Liu Qingshan now. Yes, there is no other choice.

At this time, reinforcements from another outpost position finally arrived. Including more than a dozen Men Cow Dog chariots, in addition, there are more than a dozen regional armored soldiers! Time was urgent, and Liu Qingshan was not in a hurry to reorganize this support army, so he directly ordered them to set off immediately!

――――――――――――――――――――――――――

So, soon, in mid-air, above the Great Rift Valley, "comets" appeared one by one again! Yes, behind them, there was a milky white tail flame, whistling, cutting a beautiful arc, and then, straight to the opposite side of the Great Rift Valley!

There, although a certain amount of defensive combat force was once again deployed by the alien aliens, but, after all, there were no too strong combat units, and they looked helpless in the face of Liu Qingshan's dozen regional armored soldiers falling from the sky.

Immediately afterwards, the dozen or so regional armored soldiers once again began to attack the target with dense laser beams! With his own life and blood, he once again captured a beachhead! A beachhead soaked in the blood of too many warriors! Then, Liu Qingshan used a large air transport plane to transport the dozen or so menniu dog chariots. In this way, even if some enemy air attack forces came over, Liu Qingshan was not very worried.

―――――――――――――――――――――――――――

In this case, Liu Qingshan knew that his top priority was to quickly consolidate this area and gain a firm foothold. Then, here again, the outpost base across the Great Rift Valley, will be transferred. As long as you build the Tybron ore refinery here, then you will basically succeed. You must know that you were only beaten so badly by the other party just now, and an outpost base that has been built almost completely was destroyed by the other party, which is a great shame for yourself, and it is a great shame for yourself!

Then, Liu Qingshan scattered all the combat forces that had flown over the Great Rift Valley around the Tiberon mine. Then, just wait for the arrival of that reconnaissance vehicle. However, that reconnaissance vehicle is in production! Although it is said that the production of that kind of reconnaissance vehicle does not need to consume too much production and construction funds, the problem now is that Liu Qingshan has no money on hand!

"Sell, sell! This is the only way to get production and construction funds! Liu Qingshan thought helplessly.

However, there are not many military facilities left in his own outpost base on the other side of the Rift Valley, which can be sold! Build a general plant, an ore refinery, and a power plant that provides the minimum power supply to the base. Therefore, these buildings naturally cannot be sold. The construction of the main factory is the core and foundation of a base; The ore refinery, which is also responsible for the task of collecting the last bit of Tabron ore here, also has a certain role, so naturally it cannot be sold.

And since then, the only one that can be sold is that one airport. Yes, although there are still four Fire Eagle fighters parked on it, it's just that now, Liu Qingshan knows very well in his heart that if there is no money, the entire outpost base will no longer be able to be saved. In this case, then, naturally, one qiē and one qiē will not be able to be saved. As the saying goes, "Under the nest, the beggars have finished hatching!" ”

So, after thinking of this, Liu Qingshan gritted his teeth, stomped his feet, and gave an order, so that airfield, together with the four Fire Eagle fighters parked on it, had been sold in the blink of an eye! And this whole process, that is, only two or three minutes.

―――――――――――――――――――――――――

In fact, just that airfield is not worth much at all. But, then again, on top of that airfield, there were still four Fire Eagle fighters parked! You must know that if each Fire Eagle fighter is in production, it will cost at least 3,000 production and construction funds! Now, even if it is sold at a discount, it will be discounted by some price, which is probably just the way it can be sold back to 7% off. That's a pretty good sum of money!

In this way, not long after, the airfield, along with the four Firehawk fighters on it, were all sold. Although Liu Qingshan's heart was very heartbroken, he had no choice. Subsequently, it was with the use of the production and construction funds that were sold that Liu Qingshan finally produced the survey car.

Yes, you know, if there is no such reconnaissance vehicle, then it is impossible to extend the influence of your base to the other side of the Great Rift Valley. Moreover, that kind of reconnaissance vehicle can roar large air transport aircraft. In this way, although this kind of reconnaissance vehicle does not seem to have much value, it can often play an extremely huge role at critical moments.

―――――――――――――――――――――――――――

In this way, after Liu Qingshan spent a certain amount of production and construction funds very generously, next, a large air transport plane arrived at the request. Then, immediately afterward, I saw the large air transport plane descend from the sky, and, then, the survey vehicle that had just been produced was hoisted onto it, and then, flying over the Great Rift Valley, was finally transported to the vicinity of the Tiberon deposit on the opposite side of the Great Rift Valley.

Seeing that the reconnaissance vehicle was finally transported here, the excitement in Liu Qingshan's heart was almost needless to say. He knew that with the arrival of this reconnaissance vehicle, it basically meant that on the opposite side of that rift valley, here, he would really gain a foothold. Now that he has the right to collect ore resources, then he Liu Qingshan is still afraid of a bird!

"Unfold!" In this way, with Liu Qingshan's order, the survey vehicle finally unfolded slowly, and at the edge of the Tiberon deposit, it unfolded into an outpost in the true sense.
