As a result, one after another, shells fell from the sky, whistling, and landed on Liu Qingshan's regional armored troops and Feng. Although the armored troops in that area were well defended, in the face of such a dense bombardment, some of them were still tightly packed, and some even directly lost their combat capability. Moreover, at this time, the enemy's follow-up Scorpion tanks, which numbered twenty or thirty, had already attacked. For a time, the form became extremely critical.

However, now, Liu Qingshan saw that the heavy armored combat units that had set off from his individual base were still on the mainland, and they were still at least 78 minutes away from here. Liu Qingshan knew that the remaining 78 minutes were very critical for him. That was to decide the outcome of both sides, and Cui was so busy that he was angry. However, looking at the dense combat forces gathered from all directions on the side of the Unholy Alliance, in particular, the twenty or thirty Scorpion tanks that had rushed to the front of their defensive positions, they had already formed an absolute offensive advantage over the remaining dozen or so regional armored troops. In this case, his own, the dozen or so regional armored soldiers, may be wiped out at any time.

"In any case, you must stick to seven to eight minutes!" Liu Qingshan clenched his teeth, his eyes widened, and he said fiercely. However, in this case, how to build and hold seven to eight points, Liu Qingshan knew that this was definitely not an empty word. With these infantry combat forces in their own defensive positions, it can be said that it is too difficult to accomplish this task.

Suddenly, Liu Qingshan shouted: "Sonic cannon attack, give me full support!" ”

Judging by the current situation, the situation on the battlefield is not optimistic at all. Yes, in the face of the arrival of such a fierce brigade of men and horses on the enemy side, to be honest, Liu Qingshan knew very well in his heart that the line of defense he had carefully built on that transportation artery was actually very fragile. At best, that is, it can withstand the temporary attack of the enemy army, and after a long time, it will definitely not work.

Therefore, when more and more combat forces of the enemy army appeared here, Liu Qingshan had already realized that it was now an extremely critical moment. In this case, Liu Qingshan knew that if he didn't take some emergency measures, it would definitely not work. So, after thinking of this, therefore, at the critical moment, Liu Qingshan thought of his other air support force, the light wave cannon, to attack.

It should be said that this light wave cannon is very suitable for attacking enemy forces in a large area. Apologize, in the face of seven hundred enemy combat units, swarming to use this light wave cannon to attack it in a large area, it should be said, is a very good opportunity. So, after thinking of this, with Liu Qingshan's order, suddenly, on the ground, in the middle of the enemy's dense group of various attack combat troops, suddenly, there was a continuous sound of explosions. At the same time, clusters of white explosive light continued to shine, and it looked as if some ripples had suddenly appeared on the wide surface of the water.

Liu Qingshan saw that the attack range of his light wave cannon this time was at least 7-8 kilometers away. Therefore, almost all the combat forces of the enemy army that rushed up were shrouded in the attack range of their light wave cannons. For a while, the screams continued one after another, and the explosions of the chariots came and went. This went on for about three minutes before it slowly came to an end.

In the face of Liu Qingshan's attack from the light wave cannon that had just risen to power, the attack combat troops of the dense group of enemy troops, in the end, discarded too many corpses and the wreckage of too many chariots, and retreated one after another. In this way, on the side of the Evil Alliance, although in the end 7,000 mobilized the vast majority of the combat forces and went to the evil center to relieve the siege, in the end, the defensive fortress built by Liu Qingshan finally played a positive and important role, and at the same time, the attack of the light wave cannon also formed a large area of casualties for the Tiqin, and finally led the enemy's attack to end in failure.

However, despite this, Liu Qingshan knows that the opposing team will not give up. It will not be long before they will make a comeback, and with their obvious numerical superiority, they will continue to charge at the line of defense they have built. Originally, Liu Qingshan had also considered that under the current situation, he must find ways to further strengthen the combat strength here. However, the mecha combat units that rushed over from their base camp were still halfway there, and they were still at least two minutes away from here. Therefore, the best way is to continue to use air transport in Guò to further strengthen the combat forces here with the help of air support. Other than that, there's no other good way.

However, Liu Qingshan also knew that his kind of air support force actually had a cooldown time. The Lone Goose Defensive Rifle Squad, the Machine Gun Squad, the Area Mounted Soldier Squad, the Sniper Squad, or another kind of large-scale aerial fire support, including light wave cannon horizontal fire support, as well as Ukrainian fighters and fire support, before the two support operations, they all have a certain cooldown. In the current situation, the only air support force that can be used is the cluster bombing of Ukrainian fighters.

－－－－－－－－－－－－－－－－－－－－－－－－

However, despite this, Liu Qingshan knew that he had to grasp the best time to bomb.

It is similar to the attack of the light wave cannon, focusing only on the cluster bombing of Ukrainian fighters, and also prefers dense targets. The denser the target, the more powerful it will be. The more it can cause a greater effect on the sand. Therefore, now, what Liu Qingshan has to do is to wait patiently, hold his breath, calm his breath, and wait for the enemy's attacking combat troops to rush up in dense air again. Then, give them another heavy blow.

Sure enough, three minutes later, the enemy's attacking combat unit gathered again, like a tide, along that communication artery, towards the defense line built by Liu Qingshan, and frantically launched another attack. So, for a time, the chariots roared, marched quickly, all kinds of infantry, fired together, and the shouts were earth-shattering, one after another. Let's not talk about anything else, just looking at this kind of formation, it can be said that it is earth-shattering and crying ghosts and gods. However, for Liu Qingshan, it is nothing at all. Because, in his opinion, what is really terrible is not the numerical superiority of the enemy, but the quality of the opponent in terms of technology and tactics. However, what made him a little disappointed was that this time, General Pierce, the former commander-in-chief of the enemy appointed by the Unholy Alliance in the Evil City, can be said to be very lame in terms of strategy and tactics this time.

If Liu Qingshan is painted, then he and his followers will definitely rush away from other directions, and continue to forcibly attack in the direction of the evil center. And definitely not to hang on this tree. However, the other party still has gathered all their combat forces, and it seems that they are invincible, and their momentum is like a rainbow, and they will not give up until they achieve their goal. But in fact, this has laid the groundwork for their final defeat.

－－－－－－－－－－－－－－－－－－－－－－－

In this way, just as Liu Qingshan saw that the enemy army had once again gathered dense combat troops, and had already attacked the edge of his large defensive position. It looks dense and very ferocious. So, under such circumstances, Liu Qingshan gave an order, and then, in mid-air, the flight formation formed by seven Ukrainian fighters roared and fell from the sky, and soon after, they were already talking about the sky above the dense combat force of the enemy. Immediately afterward, dense high-explosive bombs fell from mid-air one after another, and above the ground, all of a sudden, it became a sea of explosions.

After being attacked so fiercely, on the ground, the enemy's group of combat forces immediately became disorganized. Taking advantage of this opportunity, with Liu Qingshan's order, and then, the dozen or so regional armored soldiers who were left behind them suddenly activated the sandbags behind them, so one after another, the armored soldiers died in a very small mid-air, and the rear tail sprayed a white tail flame, and the public prosecution flew, and soon after, they each fell to the most ideal attack position. Immediately, a fierce attack began. One by one, white laser beams shot out of the air and broke through the air, killing some of the attacking infantry with one blow. Others attack the chariot and immediately knock out 60 or 70 percent of the target's health. And those combat units of the other side, because they had just suffered from Liu Qingshan's cluster bombing of Ukrainian fighters, therefore, until now, they were still six gods and masters, and they had increased, and it was precisely taking advantage of this opportunity that the dozen or so regional armored soldiers showed their might and attacked with all their might, I don't know how many of the opponent's infantry and combat vehicles were buried in their attack.

Soon after, on the side of the Unholy Alliance, the large number of combat troops, once again relieved, and then, adjusted their formation, and continued to attack.

Under such circumstances, Liu Qingshan's regional armored troops fought desperately, were not afraid of death, and went all out to block the enemy's attack. Helplessly, the number of opponents is too much, and in addition, all kinds of chariots, all kinds of infantry, mixed together, the attack ability is even more powerful. Therefore, seeing that more than a dozen of Liu Qingshan's armored soldiers were wiped out by the enemy one after another in the battle between power and the enemy. Soon after, the attacking combat troops of the group of enemy troops, like a flood of fierce beasts, had already approached the city and were launching a final attack on Liu Qingshan's defensive position.

At this time, Liu Qingshan clearly saw that his armored combat unit had finally arrived. Among them, nine Mammoth tanks, in addition, there were a dozen Marauder tanks, dozens of machine gunners and riflemen. At this critical moment, the arrival of support troops rushing from the direction of their base camp undoubtedly had a great impact on the entire battle situation. With the addition of these new forces, for a while, Liu Qingshan's combat troops, who were all very fortifications, had a great increase in morale, and the firepower of counterattacks was also clearly strengthened a lot.

Minute by minute. For Liu Qingshan, every minute is very precious. He knew that every minute of his time would cost him a lot. Therefore, next, after seeing that the enemy's attack was finally blocked, Liu Qingshan once again ordered the combat troops in the direction of the West Gate to immediately launch a general attack on the target. As a result, the Western Route Army, which was air-bounced in from the northwest, including seven Mammoth tanks (two of which had been upgraded to the three-star elite level) and a few Marauder tanks, had all destroyed the laser turret of the Zhu Weidao Monument in the center of evil at this time. At this time, the final assault was being launched with all its might towards the evil center of the enemy army, the building that looked resplendent in gold.

However, knowing that at this time, according to Liu Qingshan, he reluctantly discovered that the evil center of the enemy army that he attacked by thunderbolt was actually a phantom. Yes, it is. Despite their own combat troops, attacking with all their might, all kinds of attacking firepower hit it one after another. However, what appeared in front of him, the building that looked like a golden splendor appeared from time to time, and if there was nothing, it was not that he knew the building at all. Therefore, Liu Qingshan concluded that this was an illusion.

"It seems that the Unholy Alliance's defense of their evil center is really well-intentioned. So far, it seems that the only way to do this is to scout around and see what the reason is, and a huge building that can guide zhì to become like this. Liu Qingshan couldn't help but think to himself.

In the end, when he was helpless, Liu Qingshan dispatched seven of the most advanced reconnaissance planes to conduct a comprehensive reconnaissance of the enemy's evil city. In the end, Liu Qingshan finally discovered that in the four directions of this evil city, a strange-shaped building was built in each of the four directions. Every building is instilling some kind of energy in the direction of that evil center. After seeing this, Liu Qingshan finally remembered. Yes, she had learned that the center of evil could be guided by the help of a building that sits on a tower, and that it is completely possible to turn a tall building into some kind of phantom, which appears and disappears, and looks like nothing. In this way, to confuse the other party.

In this case, then, obviously, to the evil center that can be attacked, these four invisible towers must first be eliminated. For the completion of this task, to be honest, Liu Qingshan is still very sure in his heart. Because, in the current situation, the evil alliance has basically concentrated all their combat forces against the evil city, and is desperately trying to break through the defense line they have built, the purpose is to feel the evil center as soon as possible, and protect their evil center with all their might.

Therefore, in this case, he can send a special operations team to take out the four stealth towers. In this case, in that evil city, the enemy's defenses were already relatively weak, and even in many places, it became an empty city. Therefore, in this way, there is a high probability that the military operation to destroy the invisible tower of Nasi will succeed. Moreover, if you can send a strong combat force to complete this combat mission, then you will have a better chance of success.

After thinking of this, Liu Qingshan decided to simply turn the three-star elite-level mammoth tanks located in the direction of the south gate of the evil city into a special operations team to complete this task. Originally, according to Liu Qingshan's vision, those three-star elite-level mammoth tanks, as their general reserves, would be put into the battlefield at a critical time, and they would definitely play a surprisingly winning role. However, now, the situation is urgent, and Liu Qingshan can't take care of it so much. In any case, it is necessary to destroy the invisible tower of the four companions in the shortest possible time. Only in this way will the evil center of the enemy army be truly exposed to its own attacking firepower.

So, Liu Qingshan gave an order, and five three-star elite-level mammoth tanks immediately set off and began to attack the enemy's four stealth towers in a counterclockwise direction.

In this way, with Liu Qingshan's order, five three-star elite-level mammoth tanks rumbled, and in a deafening roar of chariots, they followed the direction of the water and followed the highway and went forward.

At this time, as Liu Qingshan expected, because of the car, basically all the combat forces were all assembled to defend their evil center. Therefore, in the process of the march of those three-star elite-level mammoth tanks, there was no strong resistance, and on the whole, the action was very smooth. In addition, five three-star elite-level mammoth tanks themselves have extremely strong combat capabilities, and even a few or even twenty or thirty main combat vehicles of the enemy army cannot stop their advance at all. Therefore, it was not long before the first invisible tower of the enemy army appeared in front of them.

Finally, the artillery fired in unison, and the heavy artillery fire attacked the invisible tower from different directions. You know, this three-star mammoth tank, that's definitely a natural killer of any building. In addition, such a number of three-star mammoth tanks attacked together, and for a while, the invisible tower of the enemy army built by itself immediately turned into a sea of fire. Then, with a bang, it collapsed and was blown into ruins.
