As the saying goes, there are 10,000 people without borders. Tens of thousands of landwalkers, as the forwards, really rushed towards the X base like a black wave. However, under the protection of the blue energy field, Base X is like a reef in the waves, no matter how turbulent the tide is, it will eventually turn into pieces and scatter all over the sky the moment it collides with the reef.

As a result, in a burst of dense sizzling sounds, countless landwalkers who intended to cross the blue energy field turned into blue coke and disappeared. Looking at the consistent blue energy field, and the landwalker who was like a fire-fighting moth in front of the blue energy field, everyone on the wall couldn't help but secretly breathe a sigh of relief. Because under such circumstances, I am afraid that no matter how many landwalkers come, they will only turn into a part of the ashes in the sky, and they will not hurt everyone in the slightest.

However, things will not always be as smooth sailing as people expect, and one thing that many people overlook is that there is a law in the world called conservation of energy. No matter what technology this blue energy field relies on to develop, maintaining this huge energy field must require a huge amount of energy. Especially when the landwalkers turn into intrusion energy fields and turn into ashes, this consumption becomes even more terrifying. I saw that after Lu Walker launched a ten-minute suicide attack, a slight ripple appeared on the surface of the energy field that was originally as symmetrical and blue as an eggshell. Looking at this small but obvious wave, the faces of those who knew something about the defensive energy field changed in unison. Especially the Void Emperor, his face instantly darkened.

"Is something wrong with the energy field?" Looking at the Void Emperor's darkened face, a bad premonition suddenly appeared in Zhou Yulong's heart.

"There are too many landwalkers breaking in, and killing them consumes too much energy. This blue energy field, I'm afraid it won't be able to support it for a long time. The Void Emperor nodded, and said in a gloomy tone: "If these landwalkers continue to fight to the death like they do now, then in less than an hour at most, this energy field will completely collapse. ”

"Damn, didn't you say that the technology of this energy field is very mature, how can it only support it for so long?" Hearing Emperor Xu's words, Zhou Yulong's face changed, and he scolded in a low voice: "An hour, an hour to use a bird." Even if you can deal with some of the Landwalkers, what about the rest of the Landwalkers and Bone Eaters? What's more, there's such a terrifying Karammon waiting outside! ”

"The technology of the energy field is very mature, but our energy technology is not mature enough." Looking at the slightly rippling energy shield, the Void Emperor sighed and said softly: "The supporting energy source of the energy field technology should have been Atlantis's magneto-fossil energy system, but due to our lack of conditions, we can only temporarily replace it with nuclear power generation. Originally, these nuclear energy sources could reasonably last for a few days, but under the attack of this density, the energy system is likely to be completely overloaded and exploded. So, we have to shut down the nuclear energy before it becomes unstable, in case the nuclear fuel inside explodes and blasts us into the sky. ”

"Since the shield needs a steady supply of energy, listen to me, turn off the shield in fifteen minutes, and let those landwalkers in." After listening to Emperor Xu's words, Zhou Yulong pondered slightly, and then said: "After letting the land walkers in, we can use the weapons and automatic defense weapons in our hands to deal with them, reduce the consumption of energy in the base, and wait until we can't stop them, and then open the protective shield, cut off their team, and intercept and kill them." Second, we can also give the shield a buffer time, so that it can be used to protect us at critical times. After all, the eight hundred bone eaters and the most terrifying minotaur hadn't done it yet. ”

"No problem, I'll go and tell them to get ready now." Looking at the Minotaur and the Eight Hundred Bone Eaters who were standing still in the distance, the Void Emperor nodded, and then said softly, "You come with me, and I will take you to the material storage warehouse by the way." The big war is coming, and you must increase your power as soon as possible. With that, the Void Emperor turned around and walked under the wall.

"Well, when the war starts, the doctors will help you protect the walls. But they have their own way of fighting, so you can leave them alone and let them play on their own. Following behind Emperor Xu, Zhou Yulong said word by word: "As for the other side of the city wall that I am responsible for, there will be ordinary soldiers of the Dragon Tooth Squad to guard it. As long as the large forces don't attack that side, I think they can still hold it with their strength. ”

"With the help of the doctors, I have a better grasp of holding the walls." Hearing Zhou Yulong's words, a smile finally appeared on Emperor Xu's face. Then, he took Zhou Yulong to the special metal storage room located in the X Research Institute.

――――――――― ―――――――――― cut ―――――――――――― line――――――――

Not long after Emperor Void and Zhou Yulong entered the research institute, the blue shield that had been surrounding the base began to slowly fade. As the blue shield became lighter and lighter, those landwalkers who had crossed the blue energy field no longer turned into char ashes and annihilated as they had done at the beginning, but fell to the ground one by one, struggling and writhing. When the blue shield was completely gone, the landwalkers who followed crossed the line of death unharmed and began to rush towards the wall at high speed.

Looking at the land walkers who were returning at high speed, the people on the fence who had already been warned were not worried. They hadn't fired yet, but they all raised their guns with solemn faces and aimed them at the landwalkers. Because they were waiting, not only for the landwalkers to come into their range, but also for the other mass killers to show their hideous fangs.

"Boom! Boom! Boom! ”

The first to strike were the huge mechanical automatic cannons, which launched a fierce bombardment when the first landwalker came within 800 meters of the wall. The precise lock-on guidance technology almost allows these accurate mechanical automatic cannons to be fired without firing within a range of 800 meters. Nearly thirty cannons fired in unison, blasting a neat crater almost eight hundred meters from the wall. And these large craters, which are almost seven or eight meters in diameter, are densely covered with the wreckage and flesh of the landers. There were even some landwalkers who were lucky enough to survive, still struggling in the artillery crater, trying to climb out of the artillery crater and continue to attack the wall.

However, the efforts of these landwalkers were doomed to be in vain, and after many days of preparation, a total of sixty of these mechanical automatic cannons were placed on the four walls of X. After the thirty mechanical automatic cannons closest to the target point were fired, the remaining thirty mechanical automatic cannons also spat out their deadly tongues of fire. Thirty shells that could explode the armor of the main battle tank almost overlapped into the craters created by the first wave of bombardment. Bombarded those who were lucky enough to not die, as well as the landwalkers who rushed up again, into minced meat.

In this way, after sixty mechanical automatic cannons fired four times in unison, that is, two hundred and forty shells, these mechanical automatic cannons finally ceased firing and entered the period of cooling and reloading. The land walkers behind quickly climbed over the cannon craters, which were already eight or nine meters deep and connected in a line like a canyon, and kept approaching in the direction of the wall.

"Dadada!"

Unbeknownst to these landwalkers, however, there are even more terrifying weapons of war waiting behind the mechanical automaton. When the first landwalker was within five hundred meters of the wall, the automatic machine guns, which occupied almost three-quarters of the entire wall, finally spat out long tongues of fire at them. Accompanied by a dense burst of gunfire, countless huge brass bullets erupted from the muzzle of the automatic machine gun, and then rained down on the landwalkers.

The lethality caused by the large-caliber bullets was so great that even the almost immortal body of the landwalker was suddenly shattered by the dense rain of bullets, and fell to the ground like a tattered cloth bag. And even if some high-level landwalkers can resist bullet rain attacks with their tough skin, they will continue to retreat because they can't withstand the huge kinetic energy brought by the bullets, and they can't get close to the wall at all. There were even many high-level landwalkers who had no scars on their bodies, but they fell to the ground with blood from their mouths and noses. That's because a lot of bullets have gotten into their bodies through their eyes, ears, mouths, and noses, and then destroyed their bodies from within.

And when countless landwalkers used the same kind of flesh and blood as shields, and approached the wall four hundred meters step by step, those terrifying mechanical automatic cannons were reloaded and cooled down again. With a burst of cannon roars that almost deafened everyone's ears, the four waves of cannon rain instantly swept away the land walkers who were close to the fence and even over the crater canyon. All that remains are cannon craters and flesh and blood wreckage, telling the horror of modern technology.

"Waste, you can't even hit such a small place. The Bone Eaters Team 1, the Defenders 123 Attack! "Look at the landwalkers who are constantly dying in the rain of bullets, but they can't get close to the wall anyway. The Minotaur finally couldn't hold it back, roared, and reissued the military order.

"Boom, boom!"

At the command of the Minotaur, a hundred fat bone eaters and three huge defenders began to leave the group and move towards the wall. Looking at the bone eaters and defenders who were slowly approaching the wall, the soldiers on the wall who knew something about biological weapons all changed their faces in unison. In particular, the killers who had participated in the sniper operation with Zhou Yulong even dodged to the sentry tower next to the wall. Because only in this place with tiles covering their heads, it is possible for them to minimize the possibility of being sprayed by venom.

"Everyone, mind you, the automatic machine gun locks onto the Landwalker, and the mechanical automaton is immediately reloaded, aiming at the defenders and bone eaters to attack. Also, Doom One is charging and ready to launch. "Just when everyone was worried about the bone eaters and defenders, the Void Emperor suddenly reappeared on top of the wall and gave orders to the researchers who were manipulating various defensive weapons.

"Yes!"

The appearance of the Void Emperor was like a shot in the arm that quickly stabilized everyone's uneasy mood, and in any case, everyone still trusted this man's strength very much. As a result, with the light sound of machine adjustments, the automatic machine gun and the mechanical automatic cannon suddenly staggered in their aiming directions, each aiming at their own target.

"Fire!"

When the mechanical automatic cannon was reloaded and cooled, the Void Emperor gave the order to fire. Because according to observations, the 100 bone eaters and defenders had already entered the cordon 1,800 meters from the wall. And this distance happens to be within the attack range of the mechanical automatic cannon.

"Boom! Rumble! Rumble! - Dada!"

After Emperor Xu's order, the thunderous cannons and gunshots began to sound in a staggered manner. The automatic machine gun was as powerful as ever, effectively halting the advance of the Land Walker troops within a range of 500 meters. However, the results caused by the mechanical automatic cannon made everyone stunned and exclaimed.

It turned out that at the moment when the cannon fired, the defenders didn't know why, as if they knew in advance that they would be hit by the shells. The bodies of the three defenders, each more than eight meters tall and wide, were connected to form a defensive line about twenty-five meters long. Sixty shells targeting the defenders and the bone eaters all fell on the three defenders. So, with the loud sound of explosions, the three defenders took four steps back in unison in the rain of four rounds of artillery. The ensuing flames and smoke engulfed them completely. But when the flames and smoke from the explosion cleared, the defender's massive swarthy body still stood in front of the bone eater like a mountain. This result undoubtedly shocked everyone and made them feel a little happy and chilled.

The reason for the chill was that only three defenders blocked the four salvos of sixty mechanical automatic cannons. It can be seen how terrifying the defender's defense is. And thinking that these defenders had been abolished by Brother Long, the people standing on the wall couldn't help but be extremely happy.

All three defenders are so perverted, if the number is multiplied by thirty-three times, then what weapons and equipment can destroy the defensive front they are composing?
