Because the terrain here is very peculiar, there are many ditches and bumps. Therefore, in this case, it is very easy to make full use of such terrain and build fortifications. Liu Qingshan knew that the alien alien three-legged alien monsters on the ground were very powerful in battle. The kind of dark blue laser beam they fired has a long attack range and great lethality, even if their mammoth tank has the reputation of the king of land warfare, but in the face of this alien alien aspect, the most powerful ground combat price, to be honest, if it is one-on-one, it is not the opponent of the other party at all.

In this case, one can only rely on fortifications, relying on that kind of hard fortification, to strengthen one's own defense capability. Now, after about ten minutes or so, the fortifications are basically completed. Five mammoth tanks drove into a deep ditch, and that deep ditch was the so-called fortification. With the defense of a deep ditch, it should be said that it can absorb and block the sharp laser beam attacks of the three-legged alien monsters that come here, so as to be able to protect themselves well.

Liu Qingshan, on the other hand, called this kind of defense a "deep ditch defense." In the world, this kind of deep ditch belongs to it, and it really plays a great role. ~~ In terms of alien aliens, those three-legged alien monsters, at this time, kept roaring, discouraged, and the long tentacles were constantly fainting, and in their eyes, the dark red evil crazy light kept shining. At the same time, one after another, a fierce dark blue laser beam shot out.

The dense dark blue laser beam of the quality inspection broke through the air like lightning one after another. Everywhere you go, the space is interesting. The fierce momentum of the battle, with the spirit of ruin, fiercely attacked Liu Qingshan's few mammoth tanks ambushed in the deep ditch. Because it was protected by a deep ditch, the laser beam was shot at and attacked fiercely.

Soon after, the health of the five Mammoth Tanks had been destroyed by the Thirty Effect. However, at this time, Liu Qingshan looked very golden. She waited silently. The three-legged alien monster that was waiting for the other party came closer.

He knew that the closer the distance, the higher the hit rate and the greater the lethality of his mammoth tank when it began to attack. Although, at that time, those mammoth tanks were stunned by the fierce attack of the other party, but, then again, even so, only calm down, can give the other party a fatal blow at the critical moment. Otherwise, even if you are in a hurry, it is very likely that you will reluctantly attack, and it will be counterproductive. Not only can it not effectively kill and injure the enemy, but it will even be directly destroyed by the enemy. For this to make sense, I, Liu Qingshan, know very well in my heart.

Finally, at this time, those three-legged alien monsters in terms of alien aliens finally approached. One hundred and fifty meters, one hundred and twenty meters, eighty meters, seventy meters, fifty meters! Attack! In this way, with Liu Qingshan's order, five mammoth tanks were poured, and at the same time, they launched a fierce attack on the alien alien three-legged alien monster that rushed to the front.

One after another, heavy shells shot out, broke through the wind, whistled, crossed arcs, and accurately hit the target, and at the same time, another attack weapon of this mammoth tank, the missile attack, also opened fire in full force. This missile attack, in fact, is mainly used for air defense. However, these missiles are often used in attacks, especially when attacking targets that are moving faster. After all, this kind of missile attack has a very good automatic guidance capability, even if the target moves extremely fast, but under the control of its own automatic guidance ability, this missile can still accurately track the target and hit it.

———————————————————————— in this case, those three-legged alien monsters in the alien alien side have taken the liberty of becoming. Yes, they didn't expect that those Mammoth tanks, which were about to be completely destroyed by their own fierce firepower, would launch such a fierce attack at the last moment, when they were only fifty meters apart.

Such a dense artillery attack, mixed with a dense missile attack, mixed together, like a storm, but there is no head and no face. As a result, for a while, the attacked satellite alien laurel tree kept roaring, obviously, she had been blinded by this fierce attack and was angry. In the midst of the continuous headers, the more intense dark blue laser beam attack began again.

However, it is a great pity that, after all, it was the couple mammoth tank, concentrating all their firepower and attacking the moving target. One can imagine how powerful the lethality is. Therefore, soon, the three-legged alien monster that had already been enraged, only after firing a laser beam attack, the last bit of health disappeared. Then, helplessly, he raised his head to the sky and let out a long roar, fluttered, fell to the ground, and soon turned into a black smoke and disappeared between heaven and earth.

Now, after finally being eliminated as a three-legged alien monster, the alien alien is obviously not in disbelief. Originally, their toe-toed three-legged alien monster can be said to be invincible. Trampling on the ground, on the bloody battlefield, on the ground of the Attorney General, on the hill of various periods, it should be said that they were very excited. It was an evil crazy excitement, it was a bloodthirsty brutal excitement.

—————————————————————————— now, however, it seems that this qiē and qiē no longer exist zài. You know, the three-legged alien monster at the front is their leader. Among the three-legged alien monsters on their roof, the comprehensive combat ability is the most powerful. But, their leader. Being wiped out is definitely a blow to them.

However, these three-legged alien monsters, as a high-level combat force in alien aliens, will naturally not stop attacking because of such a blow. On the contrary, it was not long before the scene just now completely infuriated them. That real madness, real bloodlust and brutality, is manifested once again. So, the roars continued one after another, and their eyes actually shot out a glare that shone with a dark red hopeful light. Immediately after, a dense dark blue lightning-like laser beam attacked.

Everywhere the dense laser beam passed, the sand flew and the rocks flew, the hills were tenaciously repaired, and the trees were completely destroyed. After being attacked, the five Liu Qingshan's mammoth tanks were naturally not spared. Once again, most of them lost twenty or thirty percent of their health. And now, the distance between the two sides is even closer. After being attacked, the five Liu Qingshan's mammoth tanks were naturally not spared. Once again, most of them lost twenty or thirty percent of their health. And now, the distance between the two sides is even closer.

In this case, Liu Qingshan knew that his mammoth tank was relatively more suitable for progress.

The opponent's three-legged alien monster is more suitable for long-range attacks. Therefore, now that the two sides were so close to each other, they simply did not stop doing anything, and ordered the five mammoth tanks to attack on all fronts, and suddenly drove out of that deep pit and rushed viciously towards the other side.

In fact, we can quite assume that this is indeed a kind of suicide attack. In the face of the continuous crazy lightning-like attack beams of the alien aliens, they were not afraid of death, moved forward bravely, went all out, drove their full horsepower, and rushed towards the target!

Moreover, while ramming, the shelling is still going on! Boom, boom, boom! It was a suicidal assault that bordered on madness! Before they hit the target, although one was killed by the dark blue light, and before they hit the target, although the dark blue light killed the other, in the end, the remaining four mammoth tanks still got their wish, with the help of the acceleration that had already risen, and hit the target fiercely!

You know, that kind of alien alien three-legged alien monster, although it claims to have terrifying defensive capabilities, but it is for fire attacks. In the face of the attack of these four mammoth tanks, which belonged entirely to the mechanical impact of the tank, it was difficult for them to resist!

"Bang Bang Bang Bang ~~~" That's it, even Liu Qingshan didn't expect that as his few mammoth tanks desperately hit the past, those mortar alien alien three-legged alien monsters were actually like rotten bones, with a bang, scattered all over the ground!

"Wow, damn it, it turned out to be a silver-like wax spear head!" After seeing this, Liu Qingshan couldn't help but sigh. Of course, Liu Qingshan is also clear about the reason for this, that is, it seems that the three-legged alien monster is covered with a special mecha. And this special kind of mecha has an extremely strong defensive ability against that kind of firepower attack. However, in the face of mechanical impact, it seems powerless.

In this way, with that kind of extremely powerful impact force, Liu Qingshan's four mammoth tanks tried their best and swept away! So, in the midst of that crisp noise, those three-legged alien monsters, soon after, were all crushed into a pile of bones!

――――――――――――――――――――――――

Of course, then again, in such a situation, Liu Qingshan's four mammoth tanks were also damaged, and the most powerful one actually had less than 100% health left. In this case, Liu Qingshan still felt very happy. Because, no matter what, he finally destroyed the most powerful three-legged alien monsters in the alien alien side, and finally succeeded in smashing the opponent's attempt to attack him from the northern front.

――――――――――――――――――――――――

At this time, in the command of the alien alien side, General Chelsea's face was pale, and he was angrily scolding a small leader: "Why don't you keep a certain distance from those other mammoth tanks?" Don't you know that this three-legged alien monster of ours is quite fragile in terms of mechanical impact? Your way of fighting by taking one's own shortcomings and attacking the enemy's strengths is simply stupid, that is simply stupid! ”

Subsequently, General Chelsea, who was above the angry head, was extremely angry, and ordered his subordinates to shoot the little leader who was responsible for directing the attack on the northern front just now.

General Chelsea knows very well that now, due to his battle plan for feints on the northern front this time, it will eventually go bankrupt, so the battle plan for the main offensive on the eastern front will naturally be cancelled. Yes, that's all, that's all.

Originally, he wanted to figure out the feint attack on the northern front of Guò and attract the other side to send a part of the combat force to the northern front from the direction of the eastern front to support. In that case, if you launch the main attack from the Eastern Front, you can take the opportunity to take down the opponent's military base in one fell swoop. However, the other party did not fall for it, but sent five heavy tanks from its core position, and then with excellent tactical means, it crushed its own attack this time!

"It seems that now, I can only stop for the time being! Look for a better opportunity again! There are many things that are forced to do it knowing that it is impossible, and it is destined to have no good results. The Chelsea general let out a long sigh, then turned to face the large map, and once again fell into deep thought, silent.

――――――――――――――――――――――――――

On Liu Qingshan's side, he was rejoicing at the victory just now.

Yes, of course, he knew what the significance of his victory in this battle was! The meaning is heavy dà, it is really the meaning of heavy dà! In this way, it is certain that the opponent will no longer be able to attack his position for a certain period of time. The other party's sharpness has been bruised by himself!

On the battlefield, opportunities don't always follow you. Once lost, it means that it will not be possible to have it again for a period of time.

As for himself, now, it should be said that after smashing the feint attack on the northern front in terms of alien aliens, there is completely time to readjust. Yes, it's a realignment. Now, Liu Qingshan knows that his most important task is to produce mining vehicles. At the beginning, his mining vehicle had already been destroyed by the attack on the Eastern Front by the alien aliens, and even less than ten percent was left. Without the Mining Vehicle, it would be impossible to mine the Tybron ore again. Not being able to collect Tybron ore resources means that their base construction and combat power production will be directly affected.

The truth is very simple. However, now, in Liu Qingshan's hands, there is no penny!

"You can't do it without money! You have to find a way! Liu Qingshan muttered to himself repeatedly. He knew that the alien alien side's attack on his base had only come to an end. Soon after, it will be launched again. Therefore, I must make full use of this precious time and strive to restore my production capacity. Only in this way can you truly make yourself invincible.

Looking back, Liu Qingshan found that there was a mammoth tank in his tank factory, and at this time, the production progress had reached more than 70 percent, but because the production and construction funds could not be connected, he had to stop production.

After seeing this, Liu Qingshan couldn't help but be overjoyed. Yes, that's a godsend! In this way, as long as he cancels the production plan of this mammoth tank, then he can completely give away some of the funds for production and construction. To produce a mining vehicle, only fifteen hundred production and construction funds are needed, which is enough. And from the production of the unfinished mammoth tank, the funds released for the production and construction of the tank should be sufficient!

In this way, not long after, Liu Qingshan finally used the freed up production and construction funds to produce a mining vehicle. Looking at the mining vehicle, staggering out of his own chariot factory, Liu Qingshan's eyes were almost emitting a greedy light!

Yes, it's like a chicken laying eggs and then hatching chickens from the eggs. After having this mining vehicle, then, next, you can use that rich Tybron ore resources to fully mine ore. Anyway, he has already deployed enough defense forces on the Eastern Front, and in terms of alien aliens, if he wants to do something about his mining vehicle there, it will be absolutely impossible to succeed.

"Hmph, damn it, in terms of aliens, you group of hateful aliens, this time, I will be merciless, completely uprooting all your combat forces! Either drive you back to your planet, or wipe you out cleanly! Liu Qingshan shouted through gritted teeth.

It should be said that Liu Qingshan's decision to vigorously develop his own economic strength first under the current situation is very correct. After all, if there is no money, a qiē is indeed just an empty word, without any practical meaning. Finally, after producing five mining vehicles, Liu Qingshan finally felt that now seemed to be the time! Yes, five mining trucks, one after another, are constantly collecting ore, which is indeed a huge income for Liu Qingshan's current situation.
