After thinking of this, Liu Qingshan gave an order, and as a result, his four MiG fighters all roared into the air one after another, flying straight in the direction of the enemy's super fortress. In mid-air, it immediately crossed four smooth and white tracks, which looked very eye-catching. So, just when the enemy's super fortress was about to attack Liu Qingshan's defensive position again, Liu Qingshan's four sorties of MiG fighters finally began.

Yes, when Liu Qingshan saw that it was really a super fortress of the enemy army, rushing towards his base, he was naturally shocked in his heart. Yes, you know, that kind of enemy super fortress is really not a joke. That guy has quite a lot of destructive powers.

Yes, the blow just now, although it was protected by the black hole shield of its own raid destroyer, did not cause too much damage to its base, but, then again, if you give yourself such a blow, the consequences will be very strict. Yes, it is. For this point, Liu Qingshan's heart is as bright as a mirror.

Now, Liu Qingshan has four MiG fighters in his hands, and although he has already built another airfield, due to time constraints, he has not produced four fighters. So, now, the number of their own fighters is still only those four.

Originally, Liu Qingshan knew that if he used his four MiG fighters, he could also complete the attack target. But, then again, even so, on the other side of that mountain, there were several defenders of the enemy-VX. In this case, the Defender-VX also has quite good anti-aircraft attack capabilities. In this case, his four MiG fighters will naturally suffer a great loss.

So, later, Liu Qingshan thought about it again, and he should use his bullfrog vehicle! Yes, his own kind of bullfrog vehicle, now, in his own base, there are as many as seven or eight. In this case, as long as you gather five or six of them, and then implement the Iron Curtain device on them, then it will naturally not be a problem to defeat the super fortress of the enemy army. Yes, that's definitely not going to be a problem. Even, in that case, their own MiG fighters will no longer need to be dispatched, and naturally they will not be damaged at all. Save them for when it's most critical to use them, and they'll work even better.

Yes, Liu Qingshan's idea, it should be said, is still very good. It's pretty good, indeed. In this way, the combat power is saved, and at the same time, the purpose of the super fortress that shoots down the enemy is achieved, so why not?

―――――――――

And now, Liu Qingshan already knew that the super fortress of the enemy army had temporarily retreated into the fog of war. However, Liu Qingshan knew according to the past law that it wouldn't take long, yes, it wouldn't take long at all, and that one of the enemy's super fortresses would appear again! Moreover, after that appearance, the nature will be very different from this one. Yes, it's a big difference. Why?

The reason, in fact, is also very obvious. That is, the appearance of the enemy's super fortress just now, including its attack, is actually just for the sake of temptation. Yes, it is. It's just a temptation. Therefore, after the temptation of Tong Guò, that guy has already figured out the specific situation in Liu Qingshan's base. So, when it comes up again, the situation, naturally, will be very different, and it will really be very different.

After thinking of this, Liu Qingshan gave an order, so, immediately after, Liu Qingshan gathered five bullfrog vehicles in his base at once, and then gathered them together, so that the iron curtain device could be implemented on them. Finally, Liu Qingshan saw his five bullfrog vehicles, and finally squeezed together! So, with an order, I saw that as Liu Qingshan recited the magic of the Iron Curtain device, Liu Qingshan soon saw that a dark red network suddenly enveloped his four bullfrog vehicles.

Then, as the dark red network gradually disappeared, the target chariot immediately became a scene of red and black: the whole body was cross-controlled by the red and black, and it was constantly changing, looking very strange. It looks like a piece of iron that has just come out of a steelmaking furnace, like a millstone that has endured through the ages, and like the hot magma, which is constantly tumbling, surging, and rushing, as if it has an unrivaled power. At this point, Liu Qingshan knew that the target combat vehicles had all been successfully implemented with an iron curtain device, and the duration should not be less than half a minute.

In this way, as Liu Qingshan finally carried out a successful implementation of the iron curtain device with his five bullfrog vehicles, Liu Qingshan saw that his five bullfrog vehicles were immediately "changing the old look into a new look". It's all completely dark and crimson coloring. After Liu Qingshan saw this, he already understood very well, that is, this time, the implementation of the iron curtain device of his five bullfrog vehicles was quite successful.

Yes, it was quite successful. In this way, then, this time, I will naturally have a considerable degree of success in the air defense attack of the enemy's super fortress. After thinking of this, under Liu Qingshan's personal command, his five bullfrog vehicles were black and red, and it looked like a black and red cloud, rushing towards the front of his defensive position. There, in the sky, the super fortress of the enemy army has already reappeared.

"Yaya, Lao Tzu this time, but I'm really not afraid of you! Hahahaha, come on, come on, you girl, this time, Lao Tzu will definitely let you taste it, Lao Tzu's bullfrog vehicle is amazing! Liu Qingshan shouted through gritted teeth.

At this time, the super fortress of the enemy army happened to rush straight towards Liu Qingshan's base again. The huge body, the hideous face, when it flew through the sky, the buzzing sound, made people shudder. However, now, with that quite good attack ability—of course, this is of course referring to that kind of quite powerful air defense capability—the bullfrog vehicle is there, and Liu Qingshan's heart naturally doesn't feel so uneasy.

At this time, Liu Qingshan's group of bullfrog vehicles, as many as five of them, had already rushed over. And in the middle of the air, the super fortress of the enemy army is also fully prepared. Of course, Liu Qingshan also understood that another attack by that guy was actually inevitable. Yes, it is. It's really inevitable.

However, fortunately, at this time, Liu Qingshan's five bullfrog vehicles were already far away from their bases. In this case, then, naturally, the enemy's super fortress, even if it wants to attack Liu Qingshan's base, or towards Liu Qingshan's defensive position, it will be too late. Yes, it's too late. In other words, there are already some whips that are beyond the reach of some whips.

Now, the enemy's super fortress can attack, in fact, only Liu Qingshan's five bullfrog vehicles. And as for the rest, that's simply impossible. However, Liu Qingshan's five bullfrog vehicles have now been defended by the kind of "Iron Curtain Device" implemented by themselves, so in this case, naturally, even if the enemy's super fortress is powerful, what can it do? That's okay either. After all, as long as the effect time of that kind of iron curtain device did not expire, then Liu Qingshan's five bullfrog vehicles would not be destroyed. This, for sure.

Now, Liu Qingshan saw that the enemy's super fortress was ready to attack. I saw, and then, with the screaming sound suddenly sounded, Liu Qingshan saw that a thick laser beam suddenly shot out from the top of the enemy's super fortress, the blue and white mixed laser beam, almost ionized the space, the space shook slightly, and everywhere it passed, all the trees and buildings were blown up and burned. And when the spearhead of the attack just touched Liu Qingshan's four bullfrog vehicles, it was as if out of thin air, cutting through a furrow......

However, although with the extremely thick laser beam breaking through the sky, the ground, the hillside, some of the rocks, and some of the woods were almost all destroyed, but because Liu Qingshan's five bullfrog vehicles had been implemented by Liu Qingshan with that kind of iron curtain device, they were not affected at all - of course, their health.

Yes, it is. And now, now that the super fortress of the enemy army has appeared, then, naturally, their attack has also begun. "Tom Tom Tom~~~" With the fierce sound, the extremely dense, and the crazy sound of shelling continued to sound, Liu Qingshan saw that the shells were fired away, whistling, and hit the huge monster in mid-air, the super fortress of the enemy. Moreover, because it was a five-car bullfrog vehicle, attacking the target at the same time, the health of the enemy's super fortress was actually descending and descending at a speed that was visible to the naked eye. After seeing this, Liu Qingshan couldn't help but feel very pleased.

"Well, it seems that this one of my own methods still really works! Or really right! In this case, it will definitely not be long before the enemy's Super Fortress in mid-air will definitely be shot down by itself! Well, yes, that's almost a certainty, that's almost a certainty! "Liu Qingshan is now full of confidence.

Sure enough, as Liu Qingshan expected. Yes, it's exactly the same! Now, Liu Qingshan saw that the super fortress of the enemy army, now, its health value has almost reached the final critical point! Suddenly, Liu Qingshan saw that the behemoth, after losing the last bit of health, suddenly slammed it, and then, it began to roll up, and suddenly lost its balance, and then, from the middle of the air, with a strange scream, it fell! It looks like a huge meteorite falling from the sky!

"Hehe, hehe, it is said that when that kind of super fortress is shot down, especially when it explodes, it is very, quite spectacular! Well, Lao Tzu has not appreciated this beautiful and spectacular scene for a long time! Hahahaha~~~" Liu Qingshan couldn't help laughing. He laughed out loud at the fact that his five Bullfrog vehicles were finally able to shoot down the enemy's Super Fortress.

Then, Liu Qingshan began to open his eyes wide, looking at the scene that should be quite spectacular, the spectacular scene that exploded when the Super Fortress fell down and smashed to the ground. I saw that all of a sudden, he shook violently, and then he lost his balance all of a sudden, and then he rolled and roared, like an extremely huge meteorite, tumbling and falling from the air!

"Boom~~~" slammed into the ground, and then, that huge monster complex, just like that, suddenly burst open! The wreckage and fragments, large and small, were scattered and flew away, and at the same time, from the bursting core, a blue and white explosion shot out in all directions, dazzling, dazzling, and radiant. At the same time, the loud explosion sounded thrilling, and the whole space moved for it. Until the countless debris and debris of the explosion scattered and flew out, and then fell from the air one after another, scattered on the ground, but still emitting wisps of green smoke......

Seeing that his five bullfrog vehicles had finally shot down the enemy's super fortress, Liu Qingshan's heart was finally relieved. However, Liu Qingshan also knew that the enemy's attack on his base, in fact, had just begun. That's just the beginning.

Moreover, according to Liu Qingshan's understanding of the enemy army, damn it, generally speaking, the enemy army will not just produce a super fortress. Yes, it is. At the very least, at least three or five battle forts must be produced. Liu Qingshan still knows this very well. Therefore, although now, he has finally defeated the enemy's super fortress, but in fact, there will be at least three super fortresses in the future, and they will continue to launch fierce attacks on Liu Qingshan's base in the near future! Moreover, that kind of attack will be even more powerful than this first time!

―――――――

"Wow, rely on him, if Lao Tzu encounters the enemy's super fortress again, when he attacks his base, what kind of combat force will he use to deal with it? You must know that although the bullfrog vehicles you have now still have a considerable number, of course, Lao Tzu understands that once there is no protection of that kind of iron curtain device, then the bullfrog vehicles with those empty ones will not be able to play any role at all! Yes, that's exactly what it is!

"After that guy attacked with a laser beam, his own bullfrog vehicles, hehe, not to mention five or six, even more than ten, couldn't withstand that guy's sexual attack! Yes, that kind of attack, that kind of attack of the enemy's super thick laser beam, should be called 'God's Breath'! Liu Qingshan couldn't help but think to himself.

Yes, indeed! If you don't have the protection of that kind of iron curtain device, then if you want to use that kind of bullfrog vehicle to carry out air defense attacks, it will definitely not work. Yes, that's definitely not going to work. For this point, Liu Qingshan's heart is clearer than anything else, it really is clearer than anything else!

However, herein lies the problem. Yes, it is indeed here. Because now, Liu Qingshan saw that the cooling time of his own iron curtain device had not arrived. In other words, now, it will take at least a minute and a half for Liu Qingshan's attack time to attack the Iron Curtain device again. And in this period of time, if the enemy's super fortress rushes over again, then how will you deal with it?

However, although the problem is a problem, soon, Liu Qingshan is no longer worried. Yes, for some time now, due to the excellent protection of his two raid destroyers, now, Liu Qingshan's base has basically not been damaged at all. At the same time, because he built two ore refineries in the early days of the base, it should be said that the amount of production and construction funds in his base will definitely not be too low.
