Fortunately, the seven raid four-wheel drive vehicles are becoming more and more courageous at this time, although its machine gun attack is not very lethal, but, after all, it is outside the range of the enemy's missile attack, and it can attack the target. In this way, it took some more time, but the final result was that the civil buildings in front of the four fortresses were knocked down.

And after losing the protection of the building, the enemy's missile squad is not vulnerable at all, and after a painful bullet is fired, it hits them so much that they are holding their heads and running away, crying for their father and mother! After that, the arrogant guys whose psychological defense line had long since collapsed finally died under the dense bullets.

After eliminating the surrounding armament, the enemy's third fortress was completely displayed in front of him! Give an order, attack with all your might! Fortunately, although this kind of enemy fortress building looks solid and powerful, its defensive capabilities are not very strong. In particular, it does not have armed forces of its own, and it is just allowed to attack with all its strength by Liu Qingshan's few raiding four-wheel drives! After a long time, the other side has no reinforcements to come, and the consequences can be imagined.

……

In this way, finally, after a period of searching and attacking, the four fortresses that the enemy had built around their sub-bases were finally killed by themselves. However, what Liu Qingshan didn't expect was that after the four fortresses had just been destroyed, the enemy army actually launched a counterattack on their base frantically!

Moreover, every time they counterattack, they are always so clear-eyed! Sometimes, a positional war is organized, and more often than not, guerrilla warfare. Because the other party is very familiar with the terrain here, this guerrilla war is really impressive! There will always be a time when Liu Qingshan didn't expect it at all, under unexpected circumstances, he will come to him so suddenly!

As a result, it really made Liu Qingshan restless. In desperation, Liu Qingshan had no choice but to divide his combat troops into two lines: offensive and defensive. He is responsible for the direction of attack, and in terms of defense, Xiao Yiming is in charge.

Liu Qingshan repeatedly told Xiao Yiming, that is, he must protect his mining vehicle. You know, that's the lifeblood of your own side! However, when Liu Qingshan saw that Xiao Yiming was just deploying his combat forces at the entrance and exit from the mine to his base, he couldn't help but remind him: What if the other party launched an attack on him directly in the mine and when his mining vehicle was collecting ore?

The words finally made Xiao Yiming understand! So, Xiao Yiming then led the improvised defensive combat force to the mine to carry out the most direct mine guard.

Yes, Liu Qingshan knows very well in his heart, that is, as long as his own side can effectively protect his mining vehicles, then he will have enough time to fight a war of attrition with the enemy. After all, here, you are the master! Although my base here is just a simple base, it has everything.

As for himself, he led the attack combat force that had just received some replenishment, to find the next target for attack. Not long ago, the headquarters sent information that there must be something wrong with the fact that the opponent was able to attack him in such a ubiquitous way in such a short period of time, like flowing water and the wind.

And according to the reconnaissance of the headquarters, it has been basically determined that the enemy army has built a super radar station! In that super radar station, a high-power radar system was built, which completely covered Liu Qingshan's base and coordinated the operation of the entire battlefield.

So, according to the meaning of the headquarters, first find the super radar station, and then destroy it. And once the opponent after the loss of the radar station is like a deaf man, a blind man! In this way, then, it will be much easier to deal with.

And now, Liu Qingshan is leading the attack combat force that has just received a little replenishment, marching and searching in the southwest direction. There, it was a wide area that had never been explored. Therefore, it is not known what military facilities the other side is building there.

From a distance, Liu Qingshan saw a hillside, although it seemed that there was nothing special about that mountain city, but Liu Qingshan still thought that there must be something wrong with this mountain city based on his intuition! Yes, Liu Qingshan has already smelled a breath of industrialization from there. There, most likely, is one of the enemy bases!

Thinking like this, Liu Qingshan gave an order, so he led his own attack force, an attack combat force still composed of "raid motorcycles" and "raid four-wheel drives", and hurried forward. It's closer, it's closer, it's closer to that mountain city! It was only at this time that Liu Qingshan saw that this was ......

Around this mountain city, there is actually a stinky ditch that surrounds that hillside. And the source of the stinking ditch is from a dark hole at the bottom of the hillside! After seeing this, Liu Qingshan couldn't help but rush over: Stinky ditch? Industrial wastewater? Hmph, here, there must be a problem! Rush in and have a look!

――――――――――――――――――

However, at this time, Liu Qingshan found that for a period of time, the enemy seemed to be more crazy about the attack on his base. Moreover, it is obvious that the main target of the opponent's attack is basically concentrated on some of his own mining vehicles!

Originally, Liu Qingshan prepared at least five to seven mining trucks by himself just in case. However, because he was not fully aware of it for some time before and deliberately protected their safety, most of them were wiped out by sporadic or organized attacks by the enemy. So far, Liu Qingshan has been looking all over the ground, but he has only found two!

Without the mining cart, then, one's own actions are basically a game of dead chess! Economic construction will always be the premise and foundation. Of course, Liu Qingshan understands this deeply. Therefore, in this case, although Liu Qingshan knows that now, the army is quite tight, but even if it is tight, the mining vehicle must be produced!

So, Liu Qingshan once again made up his mind that the production plan of the five mining vehicles would be drawn up immediately! At the same time, in order to speed up the collection of Tyberon green crystalline ore, Liu Qingshan built an ore refinery in his temporary base......

Looking around at this mining area again, Liu Qingshan couldn't help but feel emotional. It should be said that it is an abandoned mining area. The terrain of the mine is basically very flat, and in general, it is a big crossroads. And his temporary base was built in the center of that crossroads.

Such a location feature, on the one hand, is certain that it is quite convenient for their own ore gathering. Your own mining vehicle can go to the Tiberon Green Crystal Mine in any direction to collect ore, but everything has advantages and disadvantages. On the other hand, such terrain also facilitates the harassment and attack of enemy troops on their bases. However, fortunately, Liu Qingshan still grasped the defense very tightly, and basically, he did not give the enemy a chance to directly attack his base.

So far, it should be said that the Tiberon ore in the other green crystal mining areas has been basically collected. Only the main mine on the north side is still covered with large, green Tybron ore crystals.

However, the enemy forces naturally discovered this through their reconnaissance system. As a result, the direction and focus of their attacks and harassment have shifted more and more intensively to this direction! As for Liu Qingshan, he ordered his guards to draw some troops from the base to strengthen the defense there.

――――――――――――――――――――

Now, at the foot of the plateau mountain city that he had discovered not long ago, Liu Qingshan was gathering his troops there. The follow-up combat force is marching here. Right next to that waste ditch, Liu Qingshan knew that here, it should be said, must be a stronghold of the enemy. Because, this is the boiling waste water ditch, which is an illustration! If there is no active industrial production, how can there be any wastewater!

For this, Liu Qingshan naturally knows and understands. It's just that, at present, the strength of his own attack force has been reduced quite severely, and there are less than five four-wheel drive vehicles in the raid. The long-range attack force, armed rocket troops, at this time, was already only five or six. With such combat power, if you don't get it right, it's not enough for the enemy troops guarding there to stuff their teeth.

However, in the process of Liu Qingshan's troop assembly, from that high platform on the dirt slope, the enemy actually took the initiative to attack! More than a dozen armed rocket soldiers of the enemy army, carrying a kind of double-strand long-range rocket launcher in their hands, are almost exactly the same type as their own armed rocket soldiers, a kind of combat power, and even, together with the appearance, are exactly the same.

For this kind of self, he also has armed rocket soldiers, to be honest, Liu Qingshan's heart is still really quite jealous. Because of course he knows that these guys, relying on that kind of long-range rocket attack, are still very difficult to provoke. However, fortunately, his raid four-wheel drive vehicle has decent armor and should be able to withstand it for a while.
