Because of the protracted nature of the war, Liu Qingshan already has a deep understanding of this. Therefore, in such a situation, he knew that if he forcibly launched an attack, the consequences would be unimaginable.

Therefore, under such circumstances, Liu Qingshan decided that no matter what, he should also strengthen the construction of his base. The first thing to do is to once again consolidate the achievements of its own economic construction and strive to be able to store more funds for production and construction. After all, this evil city is extraordinary, and it is impossible to make the enemy disarm and surrender in a very short time.

Therefore, Liu Qingshan repeatedly reminded himself that it was a protracted battle. There is still a long way to go. Therefore, in order to win this protracted war, the most important thing is to make adequate preparations in terms of economic construction, and to store a sufficient amount of funds for production and construction.

Not long ago, Liu Qingshantong launched those two attacks, although they also destroyed some of the enemy's military facilities, but, in general, the losses were still very large. This is also Liu Qingshan's real realization that this evil city of the Evil Alliance is not so easy to capture. After all, this evil city is the economic and political center of the enemy's army, and the evil alliance does not know how long it has been operating here, so the defensive combat force on one side is very strong, it is really the Longtan Tiger's Den, and after the attack, it is impossible to retreat with all his body. Not to mention, to destroy those important military installations inside. Therefore, after the previous attacks and operations, Liu Qingshan actually had a new understanding of this evil city.

－－－－－－－－－－－－－－－－－－－－－－－－

So, under such circumstances, Liu Qingshan gave an order to temporarily return his two three-star elite-level mammoth tanks to his base from the south gate of the evil city. Because Liu Qingshan knew that according to his previous experience, after his attack was frustrated, the ground side would definitely retaliate, so under such circumstances, it was still very necessary for him to return the two three-star elite-level mammoth tanks to his base as soon as possible to strengthen the defensive combat force of his base camp base and use them to deal with the enemy's possible counterattack.

Sure enough, not long after, seven to eight enemy Scorpion tanks and some enemy infantry, with the air cooperation of several Viper fighters, began to attack Liu Qingshan's base camp position. At the forefront were the seven to eight Scorpio tanks of the enemy. Those Scorpio tanks, all over the body, were painted with the color of red, which looked very dazzling. At the same time, one after another beams of light shot out continuously, breaking through the air, and hitting Liu Qingshan's two three-star elite-level mammoth tanks fiercely.

In this case, Liu Qingshan has nothing to get up at all, but fortunately, the health of these two three-star level mammoth tanks has been tenaciously restored to the peak state. Therefore, their attacks are very strong, very aggressive, and even, these two three-star elite-level mammoth tanks eat laser beam attacks and artillery fire attacks at the same time. Due to their very strong defenses, and at the same time, after upgrading to the three-star elite level, their excellent health self-recovery ability also allows them to be even more powerful, and in the face of the enemy's crazy attacks, they will continue to attack regardless of them. Relatively speaking, the attack of this mammoth tank is much more powerful than the attack of those Scorpion tanks of the enemy army.

Therefore, in this situation, although Liu Qingshan only used two mammoth tanks to fight back against the enemy's seven to eight Scorpion tanks, he did not have the upper hand at all. Moreover, it was not long before those enemy Scorpio tanks, which had been beaten to the brink bèi, were equipped with wire racks.

Soon after, Liu Qingshan was dispatched from his base camp to pull three newly-produced ordinary mammoth tanks. In this way, Liu Qingshan's story has naturally been further strengthened. On the enemy side, more than a dozen infantrymen, like a tide, swarmed from the left and right sides at this time. They began to attack as they charged, shouting frantically. However, at this time, just after the enemy infantry had just entered the firing range of those machine gun turrets, they saw that the dozen or so machine gun turrets high above were firing one after another.

Dada, dada...... Dense firepower burst out, forming a network of firelines one after another, completely enveloping the opposing infantry's combat forces. So, on the ground, those enemy infantry, ghosts crying wolves, screaming one after another, Liu Qingshan watched, one by one, the infantry was directly bought out, like being harvested. Above the ground, soon after, he spread across the ground, and rivers of blood flowed.

And the enemy's gold kept up with the serpent fighters, crowded to the point that since they came, naturally, they must give full play to their attack capabilities. And the main object of their attack is still their old opponent, that is, Liu Qingshan's mammoth tank. However, it is known that the air defense capability of this mammoth tank itself is also very good. Therefore, in this situation, the mammoth tank turret was equipped with an indicator missile launcher, and one ring after another was fired from anti-aircraft missiles. Between the execution of the anti-aircraft missile, the rear tail dragged the gray-white tail flame, wearing the change of the direction of flight, in the process of flying, while constantly correcting the direction of flight, and then, at high speed and quickly approaching the target, and finally hit. So, boom, boom, coax, as a burst of explosions continued to sound, in mid-air, those enemy Viper fighters, facing the air defense attack of Liu Qingshan's two three-star elite-level mammoth tanks, were powerless at all, and were quickly shot down.

――――――――――――――――――――――――

At this time, in the former enemy headquarters of the Evil Alliance, General Pearson, the former commander-in-chief of the enemy, was pacing around, and his eyes looked very anxious. Yes, right now, indeed.

At this time, a senior staff officer, standing aside, with inaudible eyes, stared at General Pierce. It looked as if he was waiting for a reply. After a while, General Pierce finally stopped pacing, turned around, and whispered to the senior staff officer: "You go and tell the leader, now, the situation is urgent, please be prepared in two ways." On the one hand, that is, continue to fight and fight to the death with the enemy. However, I mean, but still leaning towards the second aspect, which is that if it is necessary for the generation, then, be prepared in time for an early retreat.

"Because, according to the information we have now, there is no rush to attack on the ground side. This means that the other side wants to fight a protracted war for us. You know, in this situation, a protracted war is very disadvantageous for us. Because the enemy army has surrounded our evil city, the regiments. In this case, our mineral resources are very comprehensive. This has a direct impact on our economic construction. In this case, after a long time, our combat strength will definitely be unable to make ends meet, so this is very unfavorable to us.

"In this case, if we can't prepare to retreat, once we are surrounded by a large number of enemy combat forces, then, at that time, our entire unholy alliance will really be wiped out. As long as we can rush out some combat forces and preserve the foundation of our evil alliance, then the so-called stay in Qingshan is not afraid of running out of firewood. Besides, our planet Teslam has a very large land area, even if we lose this evil city, we can even be forced to move to those deserted places in desperation. Although it is uninhabited, very barren, and the mineral resources are very good marksmanship, it is precisely because of this that it is easier for us to gain a foothold there. As long as we have worked hard and tirelessly, when our combat strength has reached a certain level, we can launch a counterattack at any time to retake our evil city. ”

－－－－－－－－－－－－－－－－－－－－－－－－－

Hearing this, the senior staff officer gave General Pierce a standard military salute, and then, turning around, walked out of the former enemy headquarters.

At this point, General Pierce turned again, and he let out a long breath of relief. Yes, it should be said that the battle is going on to this state, and it is not optimistic for the future. Years of combat experience told him that now, on the base side, a larger-scale encirclement operation is brewing. In other words, the other side can only continue to fight, and once the attack is renewed, it will be ruinous for themselves and for their evil city.

Yes, it is. The more the other side is in no hurry to launch an attack, the more calm the other side will be, and the more the other side will strengthen its economic construction, which means that the other side will also be terrible. And their evil city is also in danger.

Now, General Pierce stood in front of the map with a pencil in his hand, he stared at the map and did not speak for a long time. However, he sighed one after another, looking very helpless. In the end, General Pierce drew a circle at that location on the map. Then, he ordered to a senior staff officer, "Pass my order to build an ore refining plant in the Tiberon Mine in the south gate of our evil city, Chugo. In any case, if we don't have enough money for production and construction, then we are dead. Therefore, even though at the western gate of our evil city, we have seized that Tiberon deposit, and we have seen an ore refining plant there, this military operation, although it has a relatively large home planet, but in the current situation, this risk is also very worthwhile. ”

Yes, the circle that General Pierce drew on the map with a pencil just now is the Tiberon deposit at the western gate of the Evil City. Originally, General Pearson had thought about the Tiberon deposit. Yes, it should be said that the Tiberon deposit is the closest to the city of evil. It's right on their doorstep, so to speak. However, it was precisely because of this that General Pierce felt very sad.

Yes, it is. It is far from their base camp base, away from that evil city, so close that they have to be under their noses, but in this situation, the grim shape makes them dare not go to mine. However, the development of the shape shì made General Pierce deeply realize that if he could not continue to mine some Tibron ore resources, then their production and construction funds would be depleted. In this way, without economic construction as a foundation and without the production and construction funds of the Zhugu as a guarantee, their combat strength will also lose the source of continued production.

In this case, once in the middle of the battle, after the enemy army launched an attack on the evil city, their damaged chariot combat force will not be able to be replenished in time. And this, for a force, for any armed group, is the most deadly. Therefore, it is precisely because of this that General Pierce knows that under the present circumstances, it is very dangerous to forcibly occupy the Tibron mine near the west gate of that evil city, because if the enemy army takes this opportunity to attack from the west gate of his own evil city, he will put himself in an embarrassing state of not being able to take care of himself.

So, with the order of General Pearson, the west gate of the evil city slowly opened. Immediately afterward, a combat force, a reconnaissance vehicle, headed not very far west of the Evil City, in the direction of the Tiberon Mine.

At this time, Liu Qingshan was standing in front of the big screen, also paying attention to the Tiberon deposit that the evil city had sucked into his father at the South Gate. Yes, according to Liu Qingshan's plan, since he wants to fight a protracted war with the enemy, then he must solve the problem of production and construction funds. He knew that the evil city of the enemy army was difficult to defend and attack, and the defenses inside were very good, and it could even be said to be impregnable. In this case, you must be prepared for a protracted battle.

However, if we want to fight a protracted war, logistics support is the most important thing. In the current situation, the Tiberon mine near his base camp has been almost collected. Although, on the east side of his base camp, he has occupied another Tiberon mine. However, the mistress there will be attacked by the enemy at any time. Of course, for that Taberon mine, Liu Qingshan will never let it go. However, under the current situation, Liu Qingshan planned to occupy the Tiberon Mine located at the west gate of the evil city first, and then deploy heavy troops there to consolidate the position. On this basis, the most important thing to solve is the Tiberon deposit located on the east side of his base camp.

－－－－－－－－－－－－－－－－－－－－－－－－

Therefore, in this case, Liu Qingshan Yixing sent that combat force to escort his own exploration, and also marched towards the Tyberon Mine located at the west gate of Evil City County. The same purpose as General Pierce was to capture the Tiberon Mine. At this point, it can be said that Liu Qingshan's single soldier Pearson is very rare to think of together.

Soon after, Liu Qingshan's combat unit (mainly composed of mammoth tanks, however, were all general-class mammoth tanks. Liu Qingshan was not reluctant to mobilize the two three-star elite-level mammoth tanks, because his base camp needed those two three-star level mammoth tanks even more) had already arrived at the Tyberon Mine located at the west gate of Evil City County, only a few hundred meters away. However, at this time, Liu Qingshan had already discovered that not far in front of him, there was also a force that was marching towards the mine. After seeing this, Liu Qingshan suddenly understood. It seems that the place has gone with me.

"This is really a narrow road, a narrow road! In this case, if you want to occupy this piece of Tiberon Mine, you have to destroy this combat force of the Unholy Alliance first! Liu Qingshan Z couldn't help but think to himself.

In this case, Liu Qingshan couldn't help but study it, and he found that it was difficult to deal with that combat force, which was mainly composed of seven Scorpio tanks. Behind them, a dozen enemy machine gunners were also followed. Moreover, just as Liu Qingshan continued to observe what kind of combat strength the enemy army's combat troops had, suddenly, on the left and right sides of the west gate of that evil city, two monument laser turrets were suddenly built!

－－－－－－－－－－－－－－－－－－－－－－－

After seeing this, Liu Qingshan couldn't help but feel a little confused. Of course, Liu Qingshan knew that this kind of monumental laser turret of the enemy army had a long range, great lethality, and an attack range of tens of kilometers. Under such circumstances, Liu Qingshan knew that just like the combat troops of the enemy army, they had to dodge the attack of the laser turrets of these two monuments. So, after thinking of this, Liu Qingshan had an idea, and for the time being, the enemy's combat unit was planned. Subsequently, Liu Qingshan ordered his own attack combat troops, and continued to move in another direction.
