This is really a critical moment of life and death!

At this time, Liu Qingshan felt a rare sense of crisis. It seems that if you don't want to do something, it really won't work. Liu Qingshan thought to himself.

Now, Liu Qingshan finally discovered that, in fact, the enemy's attack was basically based on ground attacks. That is, the enemy forces basically did not have an air strike force, except for at the beginning, when the enemy made three sorties of air fighters. In addition to this, basically, the enemy forces are all ground offensives.

Therefore, in this case, naturally, you only need to strengthen your ground defense capability, and you can basically do it. Now, however, the enemy's offensive has just begun, and its own defensive positions have been thrown into disarray.

"Make full use of land-based fixed defense facilities!" Liu Qingshan finally made a decision whether it was a blessing or a curse. Of course, under the current situation, Liu Qingshan has no other better choice. That's all he could be.

Liu Qingshan knew that there were two main types of land-based fixed defense facilities on his side, one was the cutting tower, and the other was the laser tower. Of course, these two different land-based fixed defense facilities also have different combat effectiveness. Among them, the main offensive combat weapon of the cutting tower is the howitzer, the composition of which is mainly composed of an energy station and three turrets.

The energy station, connected by three cables, connects the three turrets. The three turrets, on the other hand, fired cannonballs through guò to attack enemy targets. Moreover, the target that this kind of cutting turret is good at attacking, basically, it can already be said that it is mainly based on the infantry combat units of that kind of enemy.

Another type of land-based turret that can be built on its own is the laser turret. In the same way, the structure of this laser turret is the same as that of the cutting turret, which also relies on an energy station and connects the three laser towers through three cables. Its main means of attack is to rely on laser attacks, and the best target is the enemy's vehicle combat units.

However, from the point of view of cost, the cost of this laser tower is twice the cost of that kind of cutting tower.

―――――――――――――――――――

Under such circumstances, naturally, Liu Qingshan knew that he had to hurry up and build a few cutting towers as the best policy. Yes, it is. Because it is generally here, during this period of time, according to the characteristics of the enemy's attack, it is mainly a ground attack. In addition, among all the combat forces involved in the ground attack, the infantry force occupies an absolute advantage.

Therefore, in this case, it is natural that the best strategy should be to defend against the enemy's infantry attack first. It's something obvious. Among its two land-based fixed defensive combat weapons, the cutting tower is undoubtedly the most important anti-infantry combat force. Moreover, this kind of cutting tower is inexpensive, only half of the cost of the laser tower. In this case, especially under the relatively tight situation of Liu Qingshan's production and construction funds, it is natural that the construction of some cutting and cutting towers has undoubtedly become one of his only choices.

In fact, it is also thanks to Liu Qingshan's combat plan. Because in the following time, the attack of the enemy side was quite fierce. However, fortunately, in the face of the other party's crazy sniping, Liu Qingshan's freshly built cutting towers really played their role at this time!

Cutting towers, so to speak, are a sharp weapon used against infantry combat units!

The group of infantry on the other side is rushing towards here!

After seeing this, Liu Qingshan couldn't help but smile coldly, thinking to himself: It's just right, Lao Tzu just wants you to try it, what kind of attack ability does this kind of "cutting tower" have!

"Tom tom tom ~~~~" one by one cannonballs, shot out, whistling, breaking through the air! In the middle of the air, a white trail was crossed, and it went straight towards the enemy's infantry, attacking it!

"Boom boom~~~" A bang suddenly sounded, under the attack of the powerful bomb, some of the enemy's infantry, really suffered huge damage, there were more than a dozen, were directly blown into the air, and then fell down one after another, dead no longer dead.

"Haha, the first battle is won!" Liu Qingshan couldn't help but be quite excited. Yes, it should be said that so far, I have finally found a magic weapon to defeat the enemy, that is, to use this land-based fixed defensive weapon of the "cutting tower" to intercept the enemy's infantry attack force! And the actual combat results just now, Liu Qingshan found that the effect is really quite good!

―――――――――――――――――――

And in the following time, the enemy actually sent a large number of mechas. Especially that kind of Titan Mecha, it looks like it is quite large, and it should be said that the power is definitely not too small! Liu Qingshan knew that that kind of Titan mecha was a weapon that specialized in overcoming his own chariot combat units! However, in this case, it is natural that you have to come up with a countermeasure!

"Let's build a laser tower!" Liu Qingshan thought to himself in his heart.

You know, that kind of laser tower is a professional-level combat weapon against enemy vehicles! If you use them against enemy Titan Mechs, you shouldn't be wrong. So, after thinking of this, although Liu Qingshan's current production and construction funds are relatively lacking, in the long run, only by doing a good job in the defense of his own base can he get a better opportunity to attack.

Two laser towers, soon after, were finally built.

"Xiuxiu~~~" One after another, orange-red laser beams continued to shoot out, with an extremely powerful force. And the opponent's Titan mecha, after being attacked, first shook violently, and then, when the second laser beam came over again, the guy who looked very huge was finally knocked over to the ground, on all sides, like a dead elephant.

Although, in this process, it is true that some of the cutting towers or laser towers on their own side have also been violently attacked by the opponent's mechas, but, despite this, because that kind of land-based turret can be repaired at any time, it will not be killed by the enemy at once.

And, very importantly, it is certain that both the cutting turret and the laser turret are the main supply station and supply the three combat towers at the same time. Since the position of the three combat towers is at the front, it is natural that they will be the first to be attacked!

However, even if those combat towers are really destroyed, it doesn't matter. As long as you have enough funds for timely repairs, even the destroyed towers will be repaired quickly. And this is precisely the value of this kind of turret, that is, in fact, they are quite a kind of tenacious combat force.

At present, Liu Qingshan has prepared a flying combat unit, which is composed of five "poisonous night fighters." This kind of "Venom fighter" belongs to a kind of combat unit that can attack both the air and the ground, and it should be said that its combat performance is still very good. It's just that it also has a big flaw, that is, because of its relatively poor defense capability, it is simply vulnerable to the enemy's anti-aircraft firepower!

Therefore, under this circumstance, Liu Qingshan knew that if he wanted to really, if he wanted to let his air combat force, which had been formed with great difficulty, really give full play to the performance they had, then the only way was to cooperate with his ground combat forces! Otherwise, once you encounter the enemy's anti-aircraft fire, then you will have no choice at all.

―――――――――――――――――――――――

Yes, it should be said that Liu Qingshan knew very well in his heart that if there was only the corresponding ground combat infantry to cover, then, in fact, the air combat unit that had just been formed on his side should still be able to give full play to its excellent combat performance. At the very least, after combining the air attack with the ground attack, then, it is certain that the strike effect will be better than the ground attack alone. For this, Liu Qingshan knows very well in his heart.

The Tiberon mine on the left should be said to be the one that Liu Qingshan values the most. Liu Qingshan knows that as long as he can take care of that mining area, then it is certain that he will be able to truly gain a firm foothold here, so as to realize and snatch back some of the very important technical information that belongs to him!

Therefore, Liu Qingshan has always sent heavy troops to defend there, because at least half of his mining vehicles are there to collect ore. And in this case, for a long time, the largest mining area was actually very safe! The enemy forces have not yet taken an attack from there!

However, despite this, Liu Qingshan still did not dare to lift his vigilance there. After all, that piece of the Tibron mine is too important for me.
