In this way, Liu Qingshan passed guò Fire Eagle fighter plane and successfully shot down the alien alien side, three destroyer battleships. Thus, once again successfully guaranteed the security of its own Eastern Front.

Under these circumstances, Liu Qingshan's horns shone on the Eastern Front of the Mammoth heavy tanks, which had reached thirteen. You know, such a number, that is the highest number of your own mammoth tanks since the advantage. Although, among these mammoth tanks, there is no three-star elite-level storage zài. However, just with such a number, Liu Qingshan also has absolute confidence and dares to have a fierce battle with any combat force in terms of satellite aliens. Even air battleships on the alien side.

So, under such circumstances, Liu Qingshan decided that with these thirteen mammoth tanks, he should carry out a northern expedition. Yes, it is. Because Liu Qingshan knew that the last military base in the alien alien area was located in the place, about 300 kilometers away from his base camp. Moreover, this area is basically all mountainous, with strange rocks and complex terrain. There are all kinds of Gobi desert, there are five high mountains towering, and in some places there are even large areas of vast desert.

Although the terrain is complicated, for Liu Qingshan, who has now assembled thirteen heavy tanks, it is inevitable that he will be ambitious and stirring in his heart. Yes, it is. In many cases, in many situations, in the face of absolute strength, a given will inspire one's own ambitions. Full of confidence, even bordering on madness.

However, for Liu Qingshan, conducting a Northern Expedition War, in fact, is not only his huge confidence in these thirteen mammoth tanks, but also Liu Qingshan's overall battle plan. Yes, since the last military base in terms of satellite aliens is on the other side, and through its own reconnaissance satellites, it has also roughly understood the specific direction, but it is not clear to me about the terrain, landform, combat environment, climatic characteristics, and so on.

And these things, in many cases, in many cases, can determine the defeat of a war. Therefore, it is undoubtedly very important to conduct field visits to understand and grasp the specific details there. This was also one of the main purposes of Liu Qingshan's plan to carry out a Northern Expedition. Of course, if any military action or any battle plan is to be put into practice, strength is the guarantee. It's the foundation, it's the premise. Without sufficient strength, any battle plan can only be a utopian dream or even a fantasy.

Now, since he has thirteen Mammoth tanks in his hands, and all of them are assembled on the Eastern Front. In addition, Tong Guò's own Fire Eagle fighter just now participated in the battle, and very easily shot down the trivalent destroyer air battleship in terms of satellite aliens. Since then, with the cooperation and support of air combat forces, Liu Qingshan feels that his heart is more confident. As a result, Liu Qingshan organized the thirteen mammoth tanks into a special operations squad of the Northern Expeditionary Army, which was mainly composed of these thirteen mammoth tanks, and in addition, Liu Qingshan equipped it with four Fire Eagle fighters and other air force combat forces to support. In addition, in order to make up for the emptiness of his defensive position on the Eastern Front after the departure of these thirteen mammoth tanks, Liu Qingshan transferred five mammoth tanks from his base camp military base to take over the defense there.

In this way, after all the preparations were sufficient, with Liu Qingshan's order, the Northern Expedition special operations team composed of thirteen mammoth tanks officially set off. Along the way, there is a mighty and mighty place, and the place where it passes looks imposing and seems to be invincible. Yes, this mammoth tank, as the most valued main battle tank in Liu Qingshan's hands, has always been valued by Liu Qingshan, so it is recognized by it.

Relying entirely on its extremely strong defensive capabilities, in addition, there are multiple attack firepower for ground-to-air attacks, it should be said that this mammoth tank has always played a huge role in the entire combat process of Liu Qingshan. Although his speed is effective and slow, his excellent moral performance in terms of overall combat effectiveness should be more than enough to compensate for the disadvantage in speed.

Now, the thirteen mammoth tanks, in battle formation, rumbled, boomed, and kicked up a cloud of smoke and dust, leaving a deep trace of tracks rolling over the ground wherever they passed. After about three hours of travel, the thirteen mammoth tanks finally arrived at a rocky hill. This piece of rocky hill is full of strange rocks, and all kinds of boulders are all over the ground. According to the satellite map, Liu Qingshan roughly calculated that the location of this piece of chaotic stone hill was basically located in the central position between the last military base in the satellite alien and his base military base. It should be said that the geographical location here is very important. And, since there are all sorts of things around, the middle part, which is relatively flat, can be used to gather combat forces here. So, apparently, this is a natural military outpost.

－－－－－－－－－－－－－－－－－－－－－－－－－－

In this case, although along the way, Liu Qingshan's Northern Expedition special operations team did not encounter an overly powerful alien alien blocking force, they were all stragglers, and they were not vulnerable at all. However, although Liu Qingshan also had it, he knew that he was red, and he kept moving forward, moving forward, and the car kept pushing forward, knowing that he had encountered the main combat force of the alien alien, or knowing that he had driven to the vicinity of the last military base of the alien alien.

However, after thinking about it again and again, Liu Qingshan still believes that in this case, although his Northern Expedition combat team has thirteen mammoth tanks, after all, it is a lone army to go deep and ride alone for thousands of miles, which is already a taboo for soldiers. In addition, he does not have the support of the backup force, nor does he have the outpost military base as a base, so it must be too rash to continue to march.

Therefore, after thinking of this, Liu Qingshan decided to stop advancing for the time being, and gathered all his thirteen mammoth tanks in this messy stone hill. Around, strange rocks are craggy, forming a natural barrier, easy to defend and difficult to attack. If possible, you can even build an outpost position here, build a chariot factory here, and in the event of a battle, your own mammoth tank that has been damaged will not have to return to your base camp military base, and you can directly recover your health here. Yes, it is at least more than 300 kilometers from here to his base camp military base, and it will definitely take too much time to go back and forth.

In this way, after thinking of this, Liu Qingshan gave an order and assembled the Northern Expedition special operations team woven by his thirteen mammoth tanks into that messy stone hill. At the same time, Liu Qingshan gave an order and once again prepared to produce a survey vehicle. The aim, of course, is to build an outpost here. As much as possible, we must be steady, step by step, step by step, only in this way can we avoid excessive losses and truly maximize our benefits.

－－－－－－－－－－－－－－－－－－－－－－－－

However, just when Liu Qingshan had just gathered his thirteen mammoth tanks into the messy rocks, the situation suddenly changed. But a dozen medium-sized alien alien ground man-making forces, whispering, should belong to biological mechas, and quickly rushed towards here. Yes, those medium-sized alien alien biological mechas, moving very fast, brushing, brushing, brushing, in the process of action, constantly emitting a very special sound, which sounds creepy.

Soon after, the dozen or so alien alien biological mechs rushed to the vicinity of a chaotic rocky hill. Immediately after, while roaring and roaring, he began to attack Liu Qingshan's thirteen mammoth tanks in the chaotic stone hills. Whizzing, swishing, a dense stream of surface-to-surface missiles, raining down from the sky, rained down on the heads of the three mammoth tanks in a small area in the middle of the rocky hills. However, since the Mammoth Tank itself has extremely strong defense capabilities, it is nothing to give in the face of the attacks of those alien alien creatures. In addition, those strange-shaped boulders also play a very obvious defensive role. Weaken the attack effect of those alien alien creatures for a certain time.

Soon after, with Liu Qingshan's order, the thirteen mammoth tanks, relying on the barrier cover of the rocky beach, immediately began to counterattack. Knock knock, knock knock...... One after another, heavy shells continued to expand and contract with the thick and long barrel, and quickly shot out, attacking the dozen or so alien alien creatures.

At the same time, the mammoth tank shone on the missile launch vehicle gas, and it was also firing at full speed. So, for a while, the cannonballs were so crazy that they rained down on the heads of those alien creatures. Boom, boom, boom...... The sound of explosions was incessant. In the face of the fierce attack of such a large number of mammoth tank clusters, the dozen or so alien alien creatures were blinded at once. Yes, it can be said that in the face of such a strong and dense fire attack, even these alien alien creatures, in the crippled, in the brutal, in the bloodthirsty, in the madness, are powerless.

For a while, the screams continued one after another, the severed limbs and stumps were blown into the air, and the blood flowed like rivers on the ground, and the corpses were all over the ground, a mess. Soon after, the dozen or so alien alien horn gods were all wiped out in this way. It should be said that this is a typical positional defensive battle. With great vitality, with the favorable terrain, with the very strong defensive barrier, with almost no morning to the situation of its own, it was very easy to eliminate more than a dozen medium-sized biological mechs in the satellite alien side, it should be said that this was a great victory.

However, next, Liu Qingshan was also wondering in his heart, where did these medium-sized alien alien creature mecha come from? Could it be that they also came from their last base military base? coincides with himself, but also to launch an attack on his position again? This qiē, until it is confirmed, can only be a conjecture.

――――――――――――――――――――――――――

Under such circumstances, Liu Qingshan decided to leave eight mammoth tanks to garrison in this messy rocky hill, and then, at the beginning of the distillation of five mammoth tanks, went around to reconnoiter whether there was any specific situation here. For example, in terms of alien aliens, is there a combat force deployed here, or is there some military facility built around here?

The reason why Liu Qingshan considered it this way was actually very simple, because he knew that this area was basically located in the middle of his military base, the alien alien military base, and the strategic location was very important. Since he can think of this, it is very likely that the alien alien side will also think of this.

If you don't have the necessary reconnaissance here, you can understand the specific situation here, and force yourself to go deeper, then, it is very likely, you will be attacked by alien aliens. Yes, it is. As soon as they walked on their front feet, if the alien aliens were deployed here, then they would be assessed on their heels. That's for sure. At the same time, from their headquarters base, they are attacking a combat force to attack themselves head-on, so even if their mammoth tanks can fight well, they will not be able to resist at all. At any moment, there is a danger of total annihilation. For this, Liu Qingshan's heart is very clear.

Therefore, in this case, it is only because the major general has conducted a reconnaissance of this area, on the one hand, to thoroughly understand the topographical and geomorphological characteristics of this area, which will also help to carry out work in this area in the future in case the battle is limited to a stalemate. The so-called precautions, whenever you have to make some plans, make more preparations, and prevent problems before they happen, Liu Qingshan has always believed that it is still very desirable to take this point.

So, next, the five mammoth tanks immediately set off from the rocky hill and began to reconnoiter the surrounding area. With solemn strength, even as a reconnaissance unit, it is full of confidence, majestic and intimidating, and it doesn't care. It seems to have some overkill.

As the reconnaissance force composed of five mammoth tanks continued to blow into the unfamiliar area, Liu Qingshan saw that the terrain here was indeed very peculiar. You can even say that the whole environment looks very sinister. Poor mountains and bad waters, no life. Everywhere there was next door, everywhere and not even a single tree was found. In this case, it is so deserted.

"It seems that the reason why the alien aliens chose such a place as their military headquarters base is that they have taken a fancy to this. Even in a deserted place, the safety factor should be greater. Because this place is inaccessible and full of sisters, it is naturally difficult for others to find this place.

While he was on the move, not far ahead, there was a sudden burst of strange sounds. This kind of voice sounded very peculiar, which made Liu Qingshan can't help but be alert. Yes, according to his own experience, Liu Qingshan has already made a judgment now, this kind of voice is definitely not the sound of nature in nature, then, on this planet, the evil alliance so far, their strength has basically been produced by themselves, even if there are still some remnants of the defeated generals, they don't know where to hide. In the face of their growing combat strength, the Unholy Alliance will definitely not show its face lightly. So, in this case, or in such a desolate environment, what power and what else can make such a strange sound?

－－－－－－－－－－－－－－－－－－－－－－－－

Sure enough, it wasn't long before the answer came out. With the reconnaissance force of the five mammoth tanks, they continued to advance, and soon after, behind several huge and strangely shaped boulders, they suddenly rushed out dead objects and threw alien creatures.

Those alien alien creatures looked like they had a way out, with long tentacles all over their bodies, and their eyes also radiated an evil dark red light, which looked very effective. At this time, they were rushing towards Liu Qingshan's reconnaissance force at an extremely fast speed. As it continued to impact, it kept squirting new green venom from their mouths. These bright green venoms, when they streaked through the space, and even the surrounding air, made a squeaking sound, which shows how strongly corrosive the venom sprayed by these alien alien creatures is.

Soon after, the venom they spewed out was like half of the brand, and it was densely handed over to Liu Qingshan's five mammoth tanks. Suddenly, a rustling sound suddenly came out. Liu Qingshan knew that this sound was the sound made by those venoms when they were corroding their mammoth tanks. It sounds creepy and chilling.
