Now, after a period of recuperation, Liu Qingshan's base, basically, can be regarded as recovering a little bit of vitality. The two ore refineries have also been rebuilt, and the natural ore harvesting has returned to normal conditions.

At this time, Liu Qingshan considered that in fact, if he wanted to really destroy the enemy's base from that fundamental, he should base himself on a super weapon - vacuum implosion bombs, and then on the role of that kind of surface ship - dreadnought-class warships. However, at present, if we want to achieve such a strategic goal, the only way is to first stabilize the construction of our own bases and work hard to develop the economy, and this is the only way, but now, if we want to achieve such a strategic goal, the only way is to first stabilize the construction of our own bases and work hard to develop the economy.

However, things are not as simple as Liu Qingshan imagined. Yes, that's really how it is. During this period of time, although his own base has suffered great damage, the bases of those enemy troops have also suffered considerable damage, and their damage is no less than Liu Qingshan's base.

In this case, it would not be so easy for the enemy to launch a counterattack. However, however, things were beyond Liu Qingshan's imagination. The enemy's combat strength is really much faster than his own! Wow, he's a girl, I didn't expect it, I really didn't expect it!

The two enemy peacekeeping bombers, as fast as lightning, suddenly appeared in the sky above Liu Zheng's base. Then came the painful bomb drop. No, it should be the projection of that kind of air-to-surface missile. One after another, the missiles whizzed and whirled, streaked across the sky, and shot at each other. Their rear tails were all dragging the long tail flames, the long orange tail flames, and hit the target fiercely: several of their own three-star elite-level Reaper mecha in Liu Qingshan's base.

"Boom, boom, ~~~~~boom, boom" With the sound of strong explosions coming continuously, Liu Qingshan saw that among his five three-star elite-level Reaper mechas, at this time, as many as two had actually been knocked out! The huge explosive force caused the two three-star elite-level Reaper mecha to burst all at once, and the countless wrecks and fragments scattered in all directions, shooting into the sky one after another.

However, the other three Liu Qingshan's three three-star elite-level Reaper mechs naturally did not watch the surprise attack of the two enemy Reaper mechas, and began their air defense attacks in the face of the enemy's peacekeeping fighters that had already launched air-to-ground missiles. 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.

In this way, the anti-aircraft missiles fired out by Liu Zheng's three three-star elite-level Reaper mecha flew away one after another, spraying the long orange tail flame, and the two peacekeeping bombers that followed the enemy army chased after each other and roared away......

"Boom Boom Boom Boom ~~~~ Boom Boom Boom Boom ~~~~~" Finally, those few anti-aircraft missiles finally hit the target, and there was a booming explosion. One of them, after being hit, suddenly lost its balance, and then, dragging the billowing black smoke, fell from the air.

"Boom~~~" The enemy peacekeeping fighter plane fell to the ground like this, making a strong explosion sound. The wreckage and fragments of the countless warplanes scattered in all directions and shot into the air one after another......

The other enemy peacekeeping bomber, after being attacked by those dense anti-aircraft missiles, actually exploded in the air at once, and the air exploded suddenly, and the flames were everywhere, and the wreckage and debris flew away. After seeing this, Liu Zheng couldn't help but breathe a long sigh of relief.

"Wow, wow, shit, fuck! How cheap you want to make it again, hum, that's absolutely impossible, that's absolutely impossible! Liu Qingshan couldn't help but think to himself, biting his lip tightly, a little bite, and then, Liu Zheng thought about it, Liu Qingshan couldn't help but think to himself, biting his lip tightly, a little bite, and then, Liu Zheng thought about it, and then, he decided to kill the enemy's fighter!

Yes, take out the airfields of the enemy army! Because, from the perspective of ground combat strength, the ground combat strength of the enemy's army, basically, will not pose any threat to Liu Qingshan's base. And if it can pose a certain threat to Liu Qingshan's base, it is only the enemy's air combat power. In particular, those aerial bombers are quite powerful. In particular, now, Liu Qingshan knows that he belongs to the period of base restoration, and during this period, his combat strength, especially that kind of air defense combat power, is very lacking, so naturally, there will be a shortage of anti-aircraft firepower for a certain extent.

Therefore, in this case, once the enemy's air combat power comes again, then he will be really miserable. Therefore, Liu Qingshan's operational idea of "killing the airfield in the enemy's base" still has a certain amount of truth.

Moreover, this task, naturally, and understandably, fell on Liu Qingshan's "double-edged helicopters". Yes, it's those "double-edged helicopters". Now, Liu Qingshan's five double-edged helicopters have been upgraded to the three-star elite level, and the double-edged helicopters under this level have quite powerful ground attack capabilities. And a double-bladed helicopter under such a level, its ground attack ability is quite powerful. Although they do not possess that kind of anti-aircraft combat capabilities, targets on the ground, in general, will not escape their clutches.

Therefore, Liu Zheng still has considerable confidence in this kind of "double-edged helicopter" of his own Samsung elite level. After thinking of this, Liu Qingshan gave an order, and then, his five double-edged helicopters roared, rotating their huge spiral wings, and flew along the zigzag coastline towards the enemy's base.

Above the sea, the waves were turbulent, and countless seagulls were flying and flying freely above the sea. The waves are blooming, the waves crashing on the shore, rolling up thousands of piles of snow. And above that shore, there are precipices that rise like knives, cutting into the sky. In this way, Liu Qingshan's double-edged helicopters flew along the tortuous coastline towards the enemy's base......

Flew past an ore refinery that looked like it had been abandoned, and beyond that, there was the mouth of the mountain. And when he flew here, Liu Qingshan couldn't help but feel a little nervous. I remember that the last time, after leading five double-edged helicopters to fly here, just above the sea, an enemy biplane flew into the air, and Liu Qingshan's double-edged helicopters were a painful blow. As a result, as many as two were knocked down on the spot. Therefore, the shadow of that defeat has always shrouded Liu Qingshan's heart. And now, when he once again led five double-bladed helicopters to fly here, the past naturally came to his mind.

Yes, for this attack on the enemy base, it can be said that it is a retaliatory attack. Yes, you blew up Lao Tzu's two three-star elite-level Reaper mechas, then, Lao Tzu naturally wants to get them back! And his five three-star elite-level double-edged helicopters are naturally the best choice for his revenge.

Finally, Liu Qingshan's five three-star elite-level double-bladed helicopters finally flew near the enemy's base. The scene there, what made Liu Qingshan feel very happy was that the scene there looked very good. There were no enemy air defense units there to defend it. It seems that the enemy's combat preparations, the scene there, what makes Liu Qingshan feel very happy is that the scene there looks very good. There were no enemy air defense units there to defend it. It seems that the enemy's combat strength preparation is also enough. The lesson he had just given him was enough for him!

"Well, let's take out the enemy's air base first! Yes, let's take out that enemy air base first! Haha, haha, the air base, that's a nice place! It looks magnificent, but, alas, it won't be long before you're in ruins! After thinking of this, Liu Qingshan gave an order, no longer hesitated, and began to attack towards the target!

At this time, there happened to be an enemy helicopter gunship, which was produced from the enemy's air base, and slowly flew out of the opening of the heavenly warehouse. However, for Liu Qingshan, it happened to be together, becoming a live target for his five three-star elite-level double-edged helicopters. I saw that with a series of machine gun bullets firing out, the sound of "sudden burst" cannon fire continued to come, and if five double-edged helicopters fired at the same time, then the bullets of the machine gun burst out, which was almost equivalent to a rain of bullets irrigation for the target on the ground. At the same time, the kind of missiles hanging under them are also constantly being launched, "Yo Yo Yo Yo ~~~~" They all dragged a stream of orange tail flames, shooting away in that kind of parabolic trajectory, whistling and flying, making a strange sound. Then he hit the target hard.

As a result, for a while, the sky above the enemy's air base almost became a red sky. The countless orange-red missiles flew in that trajectory of that trajectory, dragging the purple-red tail flame, and the whole body was bubbling with that brilliant firelight, piercing through the clouds and fog, breaking through the wind, crossing an arc, and accurately hitting the target!

"Boom, boom, boom~~~~~boom, boom, boom~~~~~" The sound of explosions sounded one after another, and one ballistic missile after another hit the target, and the wreckage and debris of countless buildings burst one after another. Half a minute later, the enemy's air base finally lost its last bit of health, and exploded with a bang.

"Hehe, there is no enemy anti-aircraft fire yet! There is no enemy anti-aircraft fire yet! Okay, I'll just keep doing it, and then continue to fight! If I don't hurt you, you don't know how powerful Lao Tzu is~" Liu Qingshan saw that there was still no enemy air defense force rushing over, so he really put his mind at ease, in front, next to the enemy "air base" that had just been knocked out by himself, it was a military research institute of the enemy army. Liu Qingshan knew that this military research institute of the enemy army was the prerequisite for the enemy's high-level combat power to be produced. Once it is destroyed, then the enemy army will definitely not be in a short period of time, and this military research institute of the enemy army is the prerequisite for the enemy's high-level combat power to be produced. Once it is destroyed, then the enemy army will definitely not be able to do anything in a short time. There's no high-level combat power to produce, and it's still a fart!

In this way, with Liu Qingshan's order, his own three-star elite-level double-bladed helicopters once again attacked the target on the ground! "Yo Yo Yo Yo ~~~~" They all dragged a stream of orange tail flames, shooting away in that parabolic trajectory, whistling and flying, making a strange sound. Then he hit the target hard.

And just like that, another rain of bullets flew, another fuchsia flame rose into the sky, and once again countless wrecks and debris of buildings scattered in all directions, and once again the ground burst into flames. Soon after, the enemy's military research institute was once again destroyed. However, Liu Qingshan found that at this time, it was still there, and there was still no air defense combat power from the enemy! At this moment, Liu Qingshan is very happy.

"Haha, haha, yes, yes, in that case, then, Lao Tzu will give you a little color again! Kill one more military facility for you! Hehe, hehe, this is cheap, that's really ......" After thinking of this, Liu Qingshan once again led his few three-star elite-level double-bladed helicopters to attack the target again. And this time, the building of the enemy army that was attacked was a war factory of the enemy army. Yes, what a war factory means for a base, I believe that every player, even if you think about it with your toes, will get the answer.

However, this time, just when Liu Qingshan had begun to attack the enemy's war factory above the ground with his five three-star elite-level double-bladed helicopters again, on the ground, an enemy javelin soldier did not know what had appeared under Liu Qingshan's five three-star elite-level double-edged helicopters. And so the attack began!

To be honest, the anti-air attack of the enemy's javelinmen was really powerful, and Liu Qingshan did not suffer such a loss. However, now, his five three-star elite-level double-bladed helicopters are at the critical juncture of attack, and it is too late to get out of the way. Therefore, the only way to do this is to destroy the enemy's war factory first. At this time, the enemy's war factory, under the fierce attack of Liu Qingshan's five three-star elite-level double-bladed helicopters, its health value had dropped to only forty or fifty percent, and success was almost in sight.

However, at this time, the air defense attack of at least two javelinmen of the enemy army also began. I saw that the anti-aircraft missiles "whoosh~~~~~swish~~~swish~~~~swish~~~~~~~~~" The anti-aircraft missiles broke through the air from the barrel of the anti-aircraft javelin in the hands of those enemy javelinmen, roared, flew over a large arc, and then soon rushed towards the double-edged helicopters that were fighting in the middle of the air, Liu Qingshan. And this time, the roaring sound came out deafeningly, "boom, boom, boom, boom~~~~~" With the sound of continuous explosions, one of Liu Qingshan's five three-star elite-level double-bladed helicopters has been knocked out more than 30% of its health.

However, Liu Qingshan did not intend to stop like this, and still insisted on using his five double-edged helicopters to continue to attack the target with a painful onslaught. Finally, ten seconds later, the enemy's war factory was finally knocked out of the last bit of health by Liu Qingshan's double-edged helicopters, and exploded with a bang.

However, at this time, just when Liu Qingshan wanted to lead his five double-edged helicopters to retreat quickly, it was already too late. The anti-aircraft assault of the enemy javelinmen continued. And in the process of retracting and flying, Liu Qingshan's double-edged helicopter that was attacked, suddenly, with the hit of another anti-aircraft missile, the whole body shook violently for a while, and then, suddenly, it lost its balance, swayed, fell from mid-air, and then smashed the cliff, and exploded with a bang.
