Then, in the same way, Liu Qingshan once again destroyed the enemy's second ship dragged from the left ship. However, although in the end, the two ships that destroyed the enemy were dragged to the ship, but the number of mammoth tanks under his command was no longer five. Not long ago, when he was dragging his two monuments against the enemy army, he was destroyed by the fierce laser beam. So far, Liu Qingshan's hands have won three mammoth tanks. Moreover, one of them is in the general class, and the other two are in the three-star elite class. It can be seen from this that the superiority of this three-star elite-level combat unit in the process of battle is self-evident.

In this case, facing his own mammoth tanks, which were damaged by Yan Zòng, Liu Qingshan knew that if he continued like this, he would suffer even greater losses. Therefore, it is imperative that you first take a break from your seven mammoth tanks. Recharge your batteries before you can attack.

Now, Liu Qingshan finally understands that the evil center of the Evil Alliance is really not so easy to overcome. After all, this evil center, which is the last foothold of the Unholy Alliance, is also their economic and political center. Not long ago, five bloodthirsty mammoth tanks, including two three-star elite-level mammoth tanks, rushed into the evil center of this enemy army, and at first, the progress was relatively smooth. However, as time went on, more and more enemy resistance forces were encountered. In particular, in the face of the fierce attack of the enemy's four monument laser turrets, coupled with the enemy's side, they took this opportunity to mobilize the vast number of Scorpio tanks to attack, therefore, in this case, Liu Qingshan's attack combat unit felt powerless, if it persisted any longer, then the final result would be the annihilation of the entire army.

Therefore, at the last moment, Liu Qingshan sacrificed two mammoth tanks as cover, and the remaining mammoth tanks, in the end, this can be regarded as a safe departure from the land of right and wrong. Now, these mammoth tanks have been moved to safety. Here, at the very least, there is no enemy force to pursue at the moment. Here, at the forefront of the enemy's defensive positions, so to speak, people are still on the doorstep of the enemy's army. Although Liu Qingshan can also continue to withdraw his combat troops, if that happens, he will increase the prestige of the other party and extinguish his own spirit. Therefore, Liu Qingshan decided that although it was very dangerous, they still had to stay here. Of course, Liu Qingshan will also find a way to further consolidate the position of this outpost. Because, after all, he had gone through the enemy's defensive position, and although in the end, the wolf escaped unbearably, but after all, he must have dealt a blow to the arrogance of the other party.

Now, Liu Qingshan has a plan, that is, here, it is better to build his own outpost position, and at the same time, build a chariot factory. In this way, he directly deployed his troops to the enemy's doorstep, and in this case, the enemy army will definitely do everything possible to get rid of his outpost position. In this way, it will definitely become a major battleground.

At seven points of battle between the two sides, although a large number of combat units will be consumed, there is also a chance to gain more experience for your combat strength, and then upgrade to the three-star elite level. Liu Qingshan knew very well in his heart that once his Mammoth Tank was upgraded to the three-star elite level, it would have a very terrifying combat capability. However, the only way to level them up is to let them participate in more battles, gain more experience points in battle, and continue to grow and rise in the test of blood and fire, and eventually become a three-star elite level.

Only when you have a certain number of three-star elite-level mammoth tanks can you gallop in this evil center, invincible, invincible, and comfortable. So, after making this decision, Liu Qingshan immediately ordered his base camp base to produce a reconnaissance vehicle, because only with this kind of reconnaissance vehicle can he build his own outpost position.

Soon after, several reconnaissance vehicles were finally produced. From the perspective of type, the survey car is very rehabilitated, even a little small and exquisite, and the image is very ugly, without a little momentum. However, Liu Qingshan knew that even so, once this reconnaissance car felt it, it could become a control center. Within the sphere of influence formed by the control center, it is possible to build various military facilities as if it were in your own base camp, thus forming an outpost position. Therefore, it can be said that this reconnaissance vehicle is the core of the construction of an outpost position.

In fact, it can be said that at the doorstep of that evil center of the enemy army, you see an outpost position, but the main purpose is to upgrade your own combat units. It can also be said that where it is, in fact, it is a training ground. In the battle of real knives and guns, let your mammoth tank get more exercise, can gain more experience points, can maximize the speed of upgrades.

In fact, Liu Qingshan knows very well in his heart that the general-level mammoth tank, although as a heavy tank, has a very good combat ability ~~~~, but, after all, this evil center, Crouching Tiger, Hidden Dragon, is well defended, there are traps everywhere, there are traps everywhere, and there are 22 firepower pawns everywhere, once you go deep into it, you will suffer an extremely huge attack. Therefore, this evil center, it is really Longtan Tiger's Den, it is easy to carry out, but if you want to come out and get out of the whole body, it is not up to you to have the final say.

This is in this situation, Liu Qingshan decided to find death, and trying to find an opportunity to upgrade his mammoth tank as much as possible is the only way out. The Mammoth Tank, among all its combat forces, is the most powerful, and it has always been the most important. Its own defense is very good, and its attack performance is also remarkable. Ground-to-ground attacks mainly use artillery attacks, which have a long range and high lethality. Ground-to-air attacks are attacked by missiles, and this kind of missile attack has a very good ability to highly intelligently guide, and once the target is locked, it is very difficult to escape their attack.

－－－－－－－－－－－－－－－－－－－－－－－－－－

Now, Liu Qingshan sees that the survey car has finally been produced. Immediately afterwards, Liu Qingshan called an air transport plane, loaded the reconnaissance vehicle into it, and then flew towards the location of his attack front line. After all, the distance is relatively far, and there are actual kilometers. If you use that survey car and use it yourself, it will take at least half a day. This is naturally undesirable for Liu Qingshan, who is sucking today. The large transport plane, loaded with the reconnaissance vehicle, rose directly vertically into the air, and then, whistling, flew towards the designated position at high speed.

It should be said that now, the kind of air transport aircraft owned by Liu Qingshan has very good performance. First of all, it is capable of transporting a large amount of war materials, and the flight speed is very fast, I don't know how many times higher than ground transportation. It can fully meet Liu Qingshan's requirements for the transportation of strategic materials.

Although it takes a certain amount of production and construction funds to call a large transport aircraft for air transportation, this is not the same thing at all for Liu Qingshan, who attaches great importance to the efficiency of operations. After all, efficiency always comes first in the course of combat. As the saying goes, the time never comes again, and on the battlefield, the fighter plane is fleeting, so in many cases, in many cases, even if it costs some production and construction money, it is very worthwhile.

In just half a minute, that large transport plane had already transported the reconnaissance vehicle that Liu Qingshan had just produced to a designated location -- an empty field at the front of the defensive position of an evil city. There, the entrance and exit are a few hundred meters away. Then, with Liu Qingshan's order, the large transport plane slowly descended from mid-air. Yes, it's still that kind of vertical landing. You must know that now, whether it is this kind of large transport aircraft, or its own various fighters, whether it is a Ukrainian fighter or a Fire Eagle fighter, it has achieved the take-off and landing capability of vertical lift-off and vertical landing. In this way, it is certain that the efficiency of the operation will be greatly improved.

Not long after, the reconnaissance vehicle, under Liu Qingshan's order, began to unfold slowly. However, he unfolded slowly, and it took at least ten minutes from the beginning to the final completion. Liu Qingshan knew that the process of unfolding this reconnaissance vehicle was the process of transforming from the so-called reconnaissance vehicle to the core of the outpost base. Therefore, it is normal that it takes a certain amount of time. Finally, ten minutes passed. The reconnaissance vehicle finally unfolded smoothly and became the core of an outpost base. Yes, the core of this outpost position should actually be called a command center. His sphere of influence is relatively large, with this rear center as the center, and within a radius of several hundred meters, it is the sphere of influence of this command center.

Within this sphere of influence, Liu Qingshan could build the military facilities he needed as he pleased, exactly the same as in his base camp. Yes, and there are no other differences. Under such circumstances, Liu Qingshan randomly built a chariot factory, which was in the middle of his outpost position. That tank factory can release maintenance drones, and it can repair its own damaged tank combat units very effectively. Moreover, the repair function is very powerful, and it can completely repair those damaged vehicles in the shortest possible time. And this is also the fundamental reason why Liu Qingshan has to find a way to build such an outpost position at the enemy's doorstep no matter what.

Sure enough, at this time, Liu Qingshan saw that just after the chariot factory was built, the five of them were left to repair the drone, like little bees, flying up and down around the chariot factory, looking very dedicated. After seeing this, Liu Qingshan felt very relieved. Yes, it is. Owning such a tank factory is equivalent to owning a tank repair shop. Especially at the doorstep of the enemy, especially in the future, there will be an extremely brutal battle, in this case, on the one hand, you will definitely need to invest a lot of combat troops, invest a large number of chariots to fight, so that there will definitely be a lot of chariots damaged.

Yes, you have to face reality. Fighting, that's what you put in, fighting, that's what you need to sacrifice. Although, Tong guò has a certain strategy, and you can use your combat forces to defeat powerful enemy forces. Although, you can think of ways to understand reasonable strategies and tactics that can minimize casualties, reduce your own losses, and improve the efficiency of operations. However, in general, it is impossible to win a battle at a certain price. It's like the law of conservation of energy.

Since this is the case, then, Liu Qingshan knows that the only thing he can do is to make reasonable repair and maintenance means to maximize the value of each of his chariots. In this way, it is necessary to use guò maintenance means. As for the means of maintenance, it can only be provided by the construction of a tank factory. At the same time, there is also a very important aspect, that is, in the process of combat, those vehicles that are damaged and should be repaired, precisely because they have been damaged, it just means that they have accumulated a certain amount of experience in the combat process, so it is naturally very helpful for their next upgrade. Yes, it is. Wouldn't it be a pity to be attacked by a vehicle that has accumulated a considerable amount of experience points, but when it is about to rise, it is destroyed by the enemy because it has not been maintained in time?

Soon after, Liu Qingshan drove all the mammoth tanks that had just been withdrawn from the front line to the surroundings of the newly built tank factory. There was no need to look closely at all that the seven mammoth tanks that had just been withdrawn from the front line had all been damaged in a certain way. Yes, you know, they retreated from the rain of bullets, from the artillery fire, from the smoke of gunpowder. It is no exaggeration to say that it is already a miracle that they were able to retreat from the battlefield alive. However, these damaged chariots will become the objects of their next focus on training and training. Because, in the bloody battle not long ago, under the premise that they were defeated with a certain amount of health, they also severely damaged the enemy army. As a result, they have accumulated a considerable amount of experience on their own, which makes them a priority for leveling up.

At this time, Liu Qingshan saw that those maintenance drones were constantly hovering over the cheers of those damaged chariots, using their special maintenance methods, conscientiously and wholeheartedly, performing their duty of chariot maintenance. Soon after, the mammoth tanks, their health, were finally completely repaired. Soon after, Liu Qingshan sent several more mammoth tanks to join this combat unit. After all, this is the front line of battles, and large-scale fierce battles can occur at any moment. Therefore, it is necessary to intensify the deployment of combat forces here. At the same time, with several mammoth tanks that have already undergone a brutal baptism of battle, Liu Qingshan believes that in the near future, several more three-star elite-level tanks will definitely be born. And for himself, being able to train a few three-star elite-level mammoth tanks is the most important goal for him during this period of time.

Yes, it is. In fact, he didn't have to attack the enemy at this time. Because, that doesn't make sense. With his current combat ability, that is, he can penetrate into the enemy's defensive position and assault the interior of an evil city, but before there are enough three-star mammoth tanks, this can only be a meat bun and a dog without returning. After experiencing the ambush just now, Liu Qingshan already knew very well in his heart that he was definitely not able to act rashly now. What I have to do now is to strengthen the mechanism and recuperate, only in this way can I grasp the situation when the time comes.

In this way, not long after, as Liu Qingshan expected, another large-scale breakthrough operation on the side of the Unholy Alliance finally began. Yes, more than a dozen Scorpio tanks, mixed with dozens of infantry combat forces, were mighty, and from the gate of the city that was besieged by Liu Qingshan, they rushed over. Faced with the combat strength of such a large scale of enemy troops, Liu Qingshan couldn't help but be shocked. It seems that on the side of the enemy army, this time, it is really moving. However, with that tank factory and those maintenance drones, Liu Qingshan believes that this is an opportunity for himself, and it is a very rare opportunity to upgrade his tank combat unit. As long as you can grasp it well, I believe that this opportunity is very rare and very important for you.
