Now, for Liu Qingshan, it is simply a very severe test. What is certain is that the six or five Marauder tanks that are left behind are now fighting to the death for those alien aliens, and the maintenance drones that are constantly flying over the tank factory are going all out to repair the damaged Marauder tanks. However, now, after all, his subordinates only said that they had six Marauder tanks. The number is too small. In terms of alien aliens, every time they attack, dozens of combat units will be mobilized at every turn, and the momentum is huge, and the attack ability is very strong. If it goes on like this, it won't be long before the only 6 Marauder tanks they have will also be martyred, and in this case, they will definitely not last long.

－－－－－－－－－－－－－－－－－－－－－－－－－－

However, even so, Liu Qingshan would never take the initiative to contact his three-star elite-level commando Falcon. He knew that although the Seventy Falcon was born to lead that operation team, although it was his only hope, the situation of that special operations team would not be much better than his own. Their situation is even more dangerous than their own. After all, the road is long, and along the way, you will definitely encounter all kinds of alien alien combat forces. After all, that special operations team only had five regional armored troops, and seven members of the missile troop team.

In fact, Liu Qingshan knew very well that if he was only going to complete a certain reconnaissance activity, then he would naturally not be so passive. The problem is that their main task is to escort the two engineers to occupy the two power plants. Therefore, in this case, their actions will definitely be greatly involved, and the two engineers themselves do not have any combat capabilities, in this case, they must allocate a part of their forces to protect the absolute safety of the two engineers. This is the task that must be done.

However, the crux of the matter is that in this way, naturally, the speed of their movement will be greatly limited, and in this way, the safety of the entire operational detachment, because of the obvious impact on mobility and flexibility, will certainly be greatly reduced. However, that operational team is shouldering such a very difficult mission, so their situation will be even more dangerous. Liu Qingshan is naturally very clear about this.

Again, in the current situation, the only thing I have to do is to find ways to do everything possible to ensure the safety of my military base. This is a qiē army. And now, he only has six Marauder tanks in his hands, and a squad of seven to eight missiles. Relying only on these combat forces, it is obvious that it is not easy to defend one's military bases. It seems that he has to find a way.

At this time, Liu Qingshan was in the abandoned military base, repeatedly inspecting. His original intention was to learn more about the terrain, and then, make full use of the characteristics of the terrain, and fight the final decisive battle with the alien alien combat forces that are constantly besieging him. However, at this time, Liu Zhengran suddenly discovered that around the abandoned military base that had been occupied by him, there were actually four or five things that looked like dead trees. Moreover, those few things like dead trees, their position distribution is very even, very regular, obviously, this location, this distribution, with a very obvious artificial color. After seeing this, Liu Qingshan couldn't help but be stunned, could it be that those things like dead trees contained any secrets?

So, after thinking of this, Liu Qingshan had a very strange feeling, and received a knife from one of the trees that looked like a dead tree to the side of the empty one. Looking closely, I saw that that one thing was completely buried in the yellow sand, only faintly, revealing some rough outlines. Randomly, Liu Qingshan completely cleared the yellow sand above, and at this time, a guardian cannon finally appeared in front of Liu Qingshan.

After seeing this in front of him, Liu Qingshan couldn't help but be overjoyed. Guardian cannons? Wow, you know, this kind of tree or cannon, which is a land-based defense provincial military facility with very strong attack capabilities, has a pivotal role in defending the position of the base. It seems that at the beginning, the Unholy Alliance really invested enough money to defend their military base.

It's just that those same guys, aren't they also this kind of defender cannon? After thinking of this, Liu Qingshan removed the dust from the other things that looked like dead trees at a very fast speed. Sure enough, Liu Qingshan's expectations were exactly the same, and the other three were all Guardian Cannons. At this time, the excitement and excitement in Liu Qingshan's heart were naturally indescribable.

He knew that in this case, if the four Guardian cannons could work normally, then his base defense would also increase many success points. So, in this case,

In a damp mood, Cheng Hao ordered the members of the missile squad to rush over in a row, and try to see if they could still attack normally with the shield cannon.

－－－－－－－－－－－－－－－－－－－－－－－－－

So, just like that, in this situation, Liu Qingshan ordered the members of the Missileman squad to start trying to see if those Guardian Cannons could be used normally.

Of course, the members of the missile troop team, after all, they are not professional artillerymen, and their best means of attack is to use shoulder-mounted bazookas to launch missiles. However, now, Liu Qingshan has no other troops to use, and there are only seven to eight members of the Missile Troop team under the tree. So, before those alien alien creatures launched the next attack, those members of the missile team, following Liu Qingshan's order, began to try to see if those guardian cannons could be used normally.

At seventy, Liu Qingshan didn't have much hope, because, after all, this was sitting on the Guardian Cannon, in disrepair, looking mottled and rusty, and in the current situation, Liu Qingshan was desperate to get some powerful weapon support. Therefore, Liu Qingshan was looking forward to the fact that those guardian cannons would be able to get their wish and let out a roar, so that the defense of his military base would be strengthened by another layer.

At this time, the first Guardian cannon, under the control of those members of the missile troop team, suddenly let out a roar, and then, a huge cannonball, with the barrel of the cannon shining dark red explosion fire, tom, burst out, three thousand meters away, exploded.

After seeing this, Liu Qingshan's excitement at that time was indescribable. Immediately after, the second, third, and fourth Guardian cannons were able to fire normally as they wished.

Liu Qingshan knew that with these four Guardian Cannons, the level of his base's defense had naturally been further improved. In this way, Liu Qingshan believes that on his side, he can at least face the fierce attack of the alien alien, and he can hold on for at least half a day.

"God help me!" At this time, Liu Qingshan couldn't help but sigh with emotion, and kept sighing in his heart, it seems that God is giving the driver a chance, which is the so-called endless road. In the next step, he should make full use of these four Guardian cannons to further strengthen his positional defense, in this way, he can correctly kill and injure the enemy to the greatest extent, as long as he is here, he can hold out for a period of time, then it is very likely that his special operations team will be able to occupy those power plants, so that his entire strategic intention will be realized.

Sure enough, not long after, another attack on the alien alien side finally began. This time, the first to attack were four to five alien alien Shenwu fighters. These biological fighters look like a huge bat, and their flight has no rules at all, without any rules, up and down, left and right, and in this way, it naturally brings certain difficulties to the air defense attack of Liu Qingshan's missile trolley squad members.

However, at this time, under such circumstances, those members of the missile troop squad still showed a very professional level of air defense attack capability. In this case, although the alien alien biological warships were very strange and the flight trajectory was very strange, but completely relying on experience, those members of the missile troop team, almost completely relying on experience and feeling, finally shot down three of them quickly. The last moment, in this situation, he had no intention of fighting, and after being seriously injured, he dragged the billowing black smoke and fled.

－－－－－－－－－－－－－－－－－－－－－－－－

Soon after, the alien alien ground attack finally began. Rushing to the forefront, this time, is still a large number of low-level satellite creatures. These low-level alien creatures, at this moment, seem to be extremely crazy. It looked like a tidal wave, emitting a shrill scream like a tsunami.

Facing these alien alien creatures that attacked like a tide, Liu Qingshan couldn't help frowning tightly. He knew that for these low-level alien creatures, his own Marauder tanks were not very advantageous killers for them. On the contrary, once their own marauder tanks are surrounded by these alien alien creatures, the consequences will be unimaginable.

Therefore, under such circumstances, Liu Qingshan resolutely decided to use his four guardian cannons that he had just discovered, all of them to fire, and use the fierce cannonballs to deal with these low-level alien alien creatures that were as dense as the tide. So, ~~~~~ rushed out of the opportunity, Liu Qingshan gave an order, only to see that dense cannonballs were whistling, shooting out from the bitter place of the cannon barrel, and then, one after another, they fell from the sky one after another, smashing into the middle of those crazy to low-level alien alien creatures. Immediately after, boom...... Explosions suddenly sounded one after another, and at the same time, a dark red explosion of fire flashed continuously, countless alien alien creatures, their corpses were blown into the air, for a while, on the ground, in mid-air, there were filthy alien corpses everywhere, stumps and broken arms, everywhere.

In this way, basically relying entirely on the fierce attack of the four guardian cannons, in that roar, under the bombardment of the heavy shells that rained down, the seemingly invincible satellite alien creatures that attacked like a tide were finally wiped out. From this point of view, those low-level alien alien creatures seem to have a natural fear of this kind of guardian cannon.

Then began to attack, and it was the kind of three-legged alien mecha again. Liu Qingshan knew that this three-legged alien mecha was relatively speaking, the most powerful attack weapon in terms of alien aliens. Quietly, it is the most powerful ground attack weapon. These guys are huge, and they have strong attack power and even stronger defense. Like at the beginning, Liu Qingshan could only rely on that three-star elite-level commando to destroy it by explosives.

And now, Falcon, one of his own three-star elite-level commandos, is ten times more stunned and idle, and the special operations team is going to carry out a special mission. Therefore, in this situation, Liu Qingshan knew that he could only rely on the 6 Marauder tanks to fight back. Although, attacking this alien alien three-legged mecha monster with this kind of Linger Tank will not destroy it so lightly, there is no better way for him to do it now.

However, fortunately, there are also the Sisi Guardian Cannons around, and in this case, the 6 Marauder tanks that use the Sisi Guardian Cannons as auxiliary attack forces to assist them will definitely be further strengthened.

So, under such circumstances, Liu Qingshan gave orders one by one, and almost all the super combat units opened fire. Called the Guardian Cannon, 6 Marauder tanks, with all their might, full firepower, for a while, all kinds of shells, whistling away, hit the group of alien alien three-legged mecha monsters that came from one side.

So, for a while, the screams kept ringing out, not big, there would be a few aliens, after shaking a few times, and then boom, Don fell to the ground, and then never got up. Liu Qingshan knew that generally speaking, that kind of alien alien three-legged mecha monster, after Tang fell to the ground, he would really never stand up again.

Of course, as the battle continued, those satellite alien monsters, the 6 Marauder tanks of Cha Cheng Hao, got closer and closer, closer and closer. And their attack began. From their output, blue laser beams were continuously fired, and each time a few strands of the Nine Dead Trees squeezed on top of the Marauder Tank, they would always knock out about thirty percent of their health in one fell swoop. At the same time, the bitterness of the three-legged alien laurel tree, one would lose no time in spewing out purple flames one after another. These purple flames, burned all the way, seemed to be able to burn away a qiē, and even the space was slightly distorted by it.

So, just like that, in the face of such a fierce attack, Liu Qingshan saw that there were another Marauder tanks, which were finally destroyed. In this way, in the end, the chicken-headed satellite alien monster that arrived at Jinguan was finally completely destroyed under the combined attack of its own Marauder tank and Guardian cannon. However, he also paid a heavy price. Fortunately, those members of the Missilemen squad did not suffer much loss. However, his seven Marauder tanks, at this time, were only left dead. Looking at the three Marauder tanks, scarred, black smoke billowing and mottled, it seemed that the water was very strict. So, in this case, Liu Qingshan could only do them to drive to the side of the tank factory first, and accept the careful maintenance of those maintenance drones. At the same time, Liu Qingshan once again checked the Thinking Guardian Cannon, he knew that now, his Marauder Tank had lost two more, and in this case, in the next defensive battle, these four Guardian Cannons would take on the main defensive task.

And at this time, that commando Falcon, by virtue of a power plant that was also a special operations squad, was approaching. However, he found that crawling around the power plant was a medium-sized alien mech combat unit. There are as many as a few dozen alien combat units in that alien alien combat unit. And the combat power in his own hands, to chase and compare, it is simply a small thing, and there is no comparison at all. In this case, the commando Falcon, also really made a difficulty. He knew that every second in his current military base could be breached by enemy troops. Therefore, time is very precious.

However, he cannot act rashly, and once he fails, he will be wiped out at any time, not only his own life, not only this special operations team, but even his entire military base. Therefore, he must be cautious and come up with a foolproof strategy, he must occupy this power plant, and use this way to shake the enemy's army to reach the hearts of the army, so that the alien aliens must first take care of their arrival at the safety of the law protector, so that the attack on his own base will definitely be much more restrained.
