According to Liu Qingshan's plan, when the enemy's reconnaissance vehicle is deployed, the opponent's combat forces will definitely be deployed around the reconnaissance vehicle for defense.

At this time, his combat unit, from the west, launched an attack on the enemy outpost that had just been built. In this way, the enemy side will fight back with all its might. In this way, it will be possible to attract the enemy's defensive combat forces to the west side, and thus get rid of the attack of the two monument laser turrets.

Now, for Liu Qingshan, the main battlefield has become two, one is located at the south gate of the evil city, and the other is located at the west gate of the evil city. It should be said that he has invested heavily in these two battlefields. However, the types of troops invested are not exactly the same. Moreover, they all have their own emphasis.

Among them, those deployed at the south gate are mainly tank combat units. In particular, a mammoth tank dominates. The deployment in the Xinmin direction is mainly infantry combat units, including sniper combat squads, ~~ machine gunner combat squads, and regional armored combat squads. Liu Qingshan knew that the evil city mainly relied on the south gate and the west gate to keep in touch with the outside world. In this case, as long as these two gates are tightly encircled, then it is impossible for the enemy to get in touch with the outside world. In particular, wanting to go outside the city to collect ore resources has been decisively vetoed by Liu Qingshan. Not long ago, the Unholy Alliance had tried to build an ore refining plant on top of the Tiberon deposit outside the West Gate, but in the face of the powerful combat troops sent by Liu Qingshan, it had already been beaten back without a rendezvous.

Moreover, for Liu Qingshan, the military positions he deployed at the west gate and south gate of the evil city were all seen near the Tiburon deposit, so on the one hand, he besieged the evil city, and on the other hand, he also guarded the old Tiberon mine. After all, the Tiberon Mine is very important to me. Of course, I won't refuse such a double thing.

Knowledge, his own outpost in the direction of the south gate of that evil city, it seems, it seems too far away from the south gate of that evil city. In this way, it also allows those enemy combat units that come out of the south gate to choose more directions. Because, after coming out of the south gate, there are at least three roads that lead to your own defense area. Yes, it is. One of them is to pass through your own outpost position before you can reach your base camp. And for the two roads, which lead to guò in other directions, it is still possible to reach their base camp. Therefore, although it is said that most of the enemy's combat forces coming out of the direction of the South Gate are along the direction of this Tiberon mine, passing through their own outpost positions, after all, there are two other directions, which has brought a series of troubles to the security of their base camp.

Therefore, Liu Qingshan decided that his next military action was to further advance the encirclement force at the south gate of the evil city, from the vicinity of the Tibron deposit to the edge of the south gate of the evil city. Yes, it is to build your own outpost near the south gate of that evil city, at the door of the enemy's house. In this way, it is not only possible to prevent the enemy's combat forces from coming out of the south gate to attack their base camp positions through other directions and along other roads, but also to give their mammoth tanks a head-on duel with the enemy's combat forces coming out of the north and south through guò here, at the enemy's doorstep, providing more opportunities for experience points.

－－－－－－－－－－－－－－－－－－－－－－

So, after thinking of this, Liu Qingshan gave an order and ordered his base camp military base to quickly produce a survey vehicle. Then, a large air transport plane flew the survey vehicle in the direction of the south gate of the evil alliance in the shortest possible time.

Naturally, the speed and efficiency bottlenecks of transporting the survey vehicle to the designated destination are much higher with guò air transport aircraft. It only took five minutes for the large transport plane, carrying the survey vehicle that had just been produced, to the designated position. That is, near the south gate of the evil city.

At this time, Liu Qingshan saw that the large transport plane, carrying a survey vehicle, had stopped in the sky near the south gate of the evil city.

The location chosen by Liu Qingshan to build the outpost position is still very ideal. With a cliff in the back and in front on the right, is the south gate of the Evil City. In this way, it is not conducive to being besieged by enemy troops, and it is the so-called back to the mountains to enjoy the shade. However, according to Liu Qingshan's instructions, the large transport plane slowly landed in mid-air, and the altitude gradually changed from 3,000 meters to 1,000 meters, and then to 1,500 meters, and finally landed safely and securely on the ground.

However, when the large transport plane was making the final operation and releasing the reconnaissance vehicle inside, all of a sudden, a dazzling purple-red beam of light whistled through the air. That purple-red beam of light, as if it had just been idle, without any warning at all, suddenly burst over. Slammed into the large transport plane that was finishing the final touches. As a result, just such an attack, just this laser beam attack, that large transport plane, in the end, still failed to complete his last big operation step, and in the blink of an eye, with a deafening explosion suddenly sounded, it was blown into countless wreckage and debris. Of course, the survey vehicle it was carrying was not spared, and disappeared with him.

After seeing this, Liu Qingshan naturally couldn't help but be surprised. When exactly did the enemy build a monumental laser turret on the left and right sides of that southern gate? Why didn't you pay attention at all? Liu Qingshan knew that this kind of enemy monument laser turret could be said to be the most powerful one among the land-based defense military facilities of the Unholy Alliance. With a long range and a lot of lethality, even the most defended mammoth tank would be overwhelmed by the full force of this monumental laser turret, not to mention the other combat units.

Unfortunately, the large air transport aircraft that had just been destroyed had very poor defensive performance, and in this case, it was reasonable to destroy a laser beam in one fell swoop. In this case, Liu Qingshan decided not to do anything, since he had already discovered it, then he would simply destroy it. It just so happens that this is also a very good opportunity to accumulate experience points for your mammoth tank, the creation zào.

So, with Liu Qingshan's order, two mammoth tanks that had been upgraded to a one-star veteran-level tank, (these two one-star veteran-level mammoth tanks, their own health points, were very dissatisfied, and they were in a peak state) boomed, and the chariots roared, and they drove at full power, attacking towards one of the monument laser turrets located at the south gate of that evil city.

Tom tom, tom tom Cheng Hao one after another heavy shells, burst out, the cannon roared, after locking on the target, it was a painful and fierce attack. However, the two monument laser turrets were naturally not ambiguous, and suddenly, there was an extremely powerful purple laser beam, which shot out Cheng Hao knew that this laser beam contained the attack energy of the two monument laser turrets, so it was powerful and powerful.

－－－－－－－－－－－－－－－－－－－－－－－－

After being attacked by that extremely powerful fuchsia laser beam, the mammoth tank that was attacked was knocked out more than half of its health in the blink of an eye. However, fortunately, their artillery attacks have now begun to bear fruit. The monument that was attacked was magnified, and at this time, dark red flames had risen and billowing smoke, constantly surrounding the monument laser turret, and it seemed that there was not much health left.

"You must hold on to me, you must hold on to me! Hold on a little longer, and the goal will collapse! Hold on a little longer, and the target will soon collapse! At this time, Liu Qingshan was also very anxious and anxious. He was most worried that in the face of the extremely fierce laser beam attack, the mammoth tank that was attacked, very good, and Yan zhòng, would, suddenly, be unable to support it and be defeated, if that was really the case, it was very likely that his military operation would be wasted and his achievements would be lost.

Fortunately, the two mammoth tanks, in the end, with their extremely strong defensive capabilities, persevered, persevered, and vowed not to give up until they reached their goal, and in the face of the extremely fierce laser beam attack, they still continued to send one shell after another to the laser turret of the Magnetic Energy Monument located at the south gate of the evil city.

Finally, with a deafening explosion suddenly sounding, Liu Qingshan saw that the monument laser turret located on the right side of the south gate of the evil city had finally been destroyed. At this time, his own mammoth tank that was attacked was only a millimeter away from the last bit of health.

Seizing this opportunity, Liu Qingshan hurriedly produced a survey vehicle again, and then hurriedly called an air transport plane again, only to see that soon, just after the survey vehicle was produced, in mid-air, several huge air transport planes appeared out of thin air. Then, in a roar, the large transport plane slowly landed on the ground, and then, through the standard mechanical operation, the survey vehicle that had just been produced was loaded into the cabin.

Soon after, there was another roar, and the large transport plane, slowly, with a powerful thrust, rose into the air, and then, whistling, flew again in the direction of the southern gate of the evil city. This time, because Liu Qingshan had already destroyed one of the monument laser turrets. Therefore, when Xiangke, a large transport plane, finally arrived at the designated destination, and then released the survey vehicle of the situation, the whole process was relatively smooth. In addition, before that, Liu Qingshan had already sent five Mammoth tanks, which were deployed there first to prevent them from being attacked by the enemy's sudden appearance of ground combat forces.

In this way, after the survey vehicle was placed, it was quickly deployed, and it was slower to become a large empty city, because Liu Qingshan knew that this process of unfolding was not so simple, and it needed to assemble, re-run-in, and debug various components, and finally, after a period of assembly and commissioning, it could operate normally. Borrowing this time, Liu Qingshan built a base camp base to build a chariot factory, of course, the location of the construction must be near the south gate of this evil city.

Soon after, the tank factory was finally built. As a result, Liu Qingshan saw that near the south gate of the evil city of the enemy army, his right outpost position had finally been built. There, the core of the outpost position, and a chariot factory. And around that tank factory, there are constantly flying maintenance drones. For those maintenance drones that are flying, Liu Qingshan is very important.

Just now, one of the two one-star veteran-level mammoth tanks that destroyed the laser turret of the enemy monument was damaged, and at this time, it looked mottled and billowing green smoke came out from above. In this case, Liu Qingshan knew that if he was not careful, something would happen to this mammoth tank. Therefore, Liu Qingshan immediately sent this damaged one-star veteran-level mammoth tank to the area around the newly built tank factory. Immediately afterwards, I saw a few maintenance factory drones, which quickly captured the information that needed to be maintained, like bees, leaned closer, and then used a special means to repair the damaged mammoth tank. I saw that the red light flashed, and a strange sound kept coming out, and the amazing thing was that in this process, the health of the mammoth tank, which was close to collapse, was actually recovering quickly at a speed visible to the naked eye. After seeing this, Liu Qingshan couldn't help but be impressed by the maintenance ability of this kind of maintenance drone.

－－－－－－－－－－－－－－－－－－－－－－－－－

Next, Liu Qingshan planned to directly destroy the other monument turret. Moreover, it is still the two mammoth tanks that carry out this task. The reason why Liu Qingshan arranged it this way certainly has its reasons. Liu Qingshan knew that his deployment of heavy troops near the south gate of this evil city was not just to besiege the enemy army, there was a more important reason for this, that is, to take this opportunity to exercise his combat strength, so that they could gain a lot of experience points in the head-to-head confrontation with the enemy's combat troops, and quickly upgrade to a higher level.

Not long ago, the two Mammoth tanks, which were already veteran-level themselves, destroyed the enemy's laser turret, and one of them must have gained a lot of experience points. In this case, if they still destroy the other laser turret, then it is very likely that after the mission is completed, there will be one that will be further upgraded to a two-star melee level such as a three-star level. This is Liu Qingshan's wishful thinking. If you switch to other vehicles, although you can also gain a lot of experience points, after all, your ultimate goal is to be at the elite level of three stars. Therefore, only by concentrating the limited experience points on a small number of combat units can it be possible to promote him to upgrade to the three-star elite level as soon as possible.

With the experience just now, ~~ when launching an attack on the remaining monument turret, it seems that Liu Qingshan County is much more calm. In addition, just now, it was facing two monument laser turrets at the same time, and finally won the final victory. Now that one of them has been destroyed, the remaining one is naturally easier to deal with. So, two mammoth tanks attacked the past, but they fell like rain, booming, and explosions continued one after another. Soon after, the laser turret, which was to be located to the right of the south gate of the evil city, was finally destroyed. Since then, the southern gate of the entire evil city has been completely devoid of the enemy's land-based defense and combat force.

In the following period of time, from the direction of the south gate of the evil city, the enemy's combat forces continued to attack, breaking through the door, in a vain attempt to break through Liu Qingshan's siege, but in the face of Liu Qingshan's heavy troops deployed there, especially in the face of those mammoth tanks' fierce offensive and solid defense, the enemy's many attacks ended hastily and did not make any breakthrough. On the contrary, at the cost of their lives, those mammoth tanks of Liu Qingshan, gained a lot of experience points. Soon after, the two Mammoth tanks that had destroyed the two monumental laser turrets on either side of the South Gate of the Wicked City finally got their wish and were upgraded to the three-star elite level after accumulating enough experience points. So far, Liu Qingshan already has four three-star Mammoth tanks.
