Now, Liu Qingshan has built three crushing plant cranes. And the role of this kind of crushing plant crane, needless to say, is known, can provide health recovery for those injured combat forces. Naturally, for Liu Qingshan, it is indeed crucial.

Now, the enemy's main attack is still limited to that kind of air attack. Peacekeeping bombers have become the main force that bears the brunt of the attack. With the sound of whistling one after another, bombshells fell from the sky and smashed into the defensive position in front of Liu Qingshan's base, blowing up smoke and clouds that rose into the sky......

However, because Liu Qingshan has now prepared a sufficient number of bullfrog vehicles, Liu Qingshan is not too worried in the face of the enemy's successive air raids. And, more importantly, in his own base, at the edge of his own defensive position, he has already built three crushing plant cranes! Liu Qingshan wasn't too worried. And, more importantly, in his own base, at the edge of his own defensive position, he has already built three crushing plant cranes! In this case, even if it is your own air defense combat power, including the Bullfrog vehicle and the Reaper mecha, once it is attacked, then, it doesn't matter, as long as they are not knocked out all at once, then, okay, we have a way to restore it! In this case, can't the matter be solved well?

Of course, at the same time, Liu Qingshan also made plans for the next step, that is, to seize the time to build his base into a stronger one, and for the next step, he really has the strength to achieve a major counteroffensive. For this reason, Liu Qingshan decided, first, to build his own combat room, also known as the Combat Research Institute. In this way, some of their more threatening combat power will also be produced. Second, build your own shipyard. Liu Qingshan knew that as a type of Soviet combat power, his own shipyard produced excellent warships like dreadnought-class battleships.

The reason why that kind of fighter is excellent is that its attack range is quite long, and second, the missiles it launches have a long range and strong lethality. Although the guidance effect is very poor, for the kind of moving target, there is almost no automatic pursuit ability, however, for the fixed buildings of our enemy army, there is almost no automatic pursuit ability, however, for the fixed buildings of our enemy army, it has a rather unusual attack effect. Therefore, it has always been very tempting for Liu Qingshan.

And now, that combat research institute, and that shipyard, are in the process of being built. It is estimated that in another ten minutes or so, Liu Qingshan will be able to have them. After thinking of this, Liu Qingshan couldn't help but breathe a sigh of relief.

"Well, Lao Tzu can't always be beaten passively like this! Damn, he's a girl, no, no, it can't go on like this! He's a girl! Lao Tzu also has to send some combat forces to the enemy's base to inspect and prepare for the attack of the pearls! Liu Sen thought like this and decided that there was no need to send too much combat power over, because the main purpose of sending combat power over this time was to go to reconnoitre.

Therefore, Liu Sen decided to send five hammer tanks as the main ground attack force, in addition, plus three V4 missile launch combat vehicles (in preparation for production) as a long-range attack force. Also, it is necessary to keep up with at least three more anti-aircraft combat forces, because once it is attacked by the enemy's air power, then it will be really troublesome. Because once it encounters the enemy's air power, then it will be really troublesome. Therefore, without the power to shake in the air, it is also absolutely impossible. However, as for what kind of air shaking force to send over, Liu Sen really hasn't made up his mind. Although it is said that the most ideal plan is the kind of bullfrog vehicle, Liu Sen actually knows this, and it is almost irrefutable. However, the Bullfrog vehicle also has one of the biggest drawbacks, that is, it cannot be grounded, only air.

"Wow, wow, shit, fuck! In this case, if you encounter the enemy's infantry combat power, wouldn't it be broken? You must know that although your own hammer tank has quite good ground attack capabilities, it is only effective against the enemy's mecha combat power. And once it is replaced by other combat power, although it has a fairly good ground attack ability, it is only effective against the enemy's mecha combat power. And once it is replaced by other combat power, especially once it is against the enemy's infantry combat power, it will be even more troublesome! Well, yes, it's very troublesome, because in the face of the enemy's infantry combat power, basically, I just don't have the power to fight back! Wow, wow, shit, fuck!

So. After thinking about it again and again, Liu Qingshan finally decided that the anti-aircraft firepower he wanted to send over would be set on that kind of Reaper mecha! Yes, just use it! You know, that kind of Reaper mecha has quite comprehensive attack capabilities! Not only can it be against the air, but also on the ground! The kind of missiles they launch are all good for air and ground! Wow by wow, he's a girl, why didn't Lao Tzu think of this just now? Hey, hey, that's it, that's it!

Yes, yes, we must not allow the enemy to continue to run rampant. Wow, wow, he's a girl, has Lao Tzu's base been used as your training ground? Yaya, see how Lao Tzu cleans up your Yaya!

In the end, in order to strengthen the air defense force, Liu Qingshan still added three more bullfrog vehicles to the base of the combat power he had planned just now. After all, for some time now, the enemy's air strike capability has become more and more rampant. Wow, wow, shit, fuck! You can't, before you reach your destination, you'll be defeated by the enemy's air power! Wouldn't that be a loss?

All the way. And the process of marching on this road, just as Liu Qingshan expected, really encountered a large number of enemy air attacks. And among the air attacks of those enemy forces, the main one is the air bombardment of the peacekeeping bombers.

Listen, a rumbling roar is coming! Not good, Liu Qingshan has already seen two enemy peacekeeping bombers, which have already swept over the mountain, swept over the forest, and have flown over the head of his own attack team! Liu Qingshan couldn't help but be a little flustered for a while, but he himself forcibly controlled his panic and calmed down. Then, after spotting the target, an order was given, and the air defense forces of his own group were fully fired! In particular, the three bullfrog vehicles are quite good. Tom tom ~~~~ tom

The sound of continuous anti-aircraft artillery firing was endless, and one after another anti-aircraft guns roared out, cutting through the sky and drawing a series of shining fiery red tracks. After that, it hit the target - in mid-air, on the enemy peacekeeping bomber, and there was a violent explosion.

And the attack ability of those two Reaper mechs is also quite terrifying. I saw that in the face of the enemy's fierce-looking peacekeeping bombers, they did not dodge, but bravely rushed up, pointing the barrels of the special anti-aircraft guns upward, and constantly changing their positions in the same place, looking for the best attack point. Then, the attack began. I saw that with the piercing sound of "whoosh" one after another, Liu Qingshan saw that countless rockets shot out from the barrels above the battery of the group of Reaper mechas, and those dense rocket shells were dragging the orange flames, spraying the scorching main air waves, roaring away into the sky, one after another, one after another, so dense, the scene was like the spectacular scene when the salvo of rocket artillery was fired.

And with the sound of that whistling sound endlessly, one after another anti-aircraft missiles hit the target one after another. And the enemy's second peacekeeping bomber, after the successive anti-aircraft missiles broke through the wind, after they hit the target one after another, finally lost their balance at once, and then, dragging a puff of black smoke, whimpering, fell from mid-air, slammed into a dirt mountain, and exploded with a bang.

However, although the two peacekeeping bombers of the enemy army were defeated, the combat strength of Liu Qingshan's troops, too, also suffered great losses. A Reaper mech was blown up, a hammer tank was gone, and an anti-aircraft weapon, the Bullfrog vehicle, was blown up.

However, at this moment, just when Liu Qingshan felt very angry, as his expeditionary force continued to march, several enemy peacekeepers actually appeared in front! Liu Qingshan knew that although this kind of enemy peacekeeping infantry could not be compared with those heavy combat vehicles, once a cluster advantage was formed, it would be very incredible. Therefore, Liu Qingshan did not dare to be careless. However, at present, among their own combat power, only their own Reaper mecha has a certain strength to fight with them. So, there was no way, Liu Qingshan had no choice but to order his two remaining Reaper mechs once again to fire and attack the enemy's peacekeepers!
