For the sake of the strength of the entire wall, the interior is not as good as possible with more layers. Although the firepower is fierce when there are more layers, the solidity of the city wall is much worse.

For the sake of the fortification of the walls, in fact more places inside the walls are solid. There's not a lot of space to carry soldiers. But even so, it was enough for the defenders.

The order is given. Fifteen defenses of the entire city wall opened fire at the same time. For a moment, a dense layer of bullet-forming torrential rain instantly formed in front of the entire city wall. Hideously and arrogantly climbing the sea of zombies, in the face of such a torrential rain of bullets, there is almost no doubt that he was beaten into a sieve by bullets. Only a handful of zombies broke through and broke into the city walls, but were swept to death by heavy machine guns with adjusted corners.

The lucky of the few lucky ones broke through the machine gun fire net and grabbed the city wall, and the moment they touched the city wall, the body's instinct drove the zombies to climb towards the top of the city wall with their hands and feet, but then it was those zombies who were desperate. A row of sharp thorns blocked their path.

The amount of climbing the body of a zombie is not large. For the sake of his climbing characteristics, his body is weaker than ordinary zombies. Faced with a rigid thorn with a diameter of more than 30mm, there was nothing they could do. As they hesitated in front of the dense row of stabs, the soldiers of the 13th Army at the top of the city wall were carrying small small sniper rifles and firing accurately downward.

"Roar! Roar...... "The zombies roared unwillingly, and then fell to the ground and fell into a puddle of flesh. Reports of the last zombie being killed. There was a huge cheer from the entire border stronghold!

"Ahh Come on, son of a bitch. Let you brutes know how good we humans are! ”

……

"Hahaha. When they arrived, I asked them to taste the heavy machine gun bullets! A soldier waved his hands, which were a little numb from the shot he had just taken, but his face was still full of excitement......

The entire frontier stronghold was in a state of triumph. This time, the human soldiers who were located inside the stronghold of the first and second border passes were mostly recruits who had not experienced a large-scale zombie extermination war. Although they have been trained as recruits, they have not actually had time for a major battle to temper them.

Today, many of them are on this kind of large-scale battlefield for the first time, although it may not be the first time to kill zombies, but in the face of this overwhelming sea of zombies, the vast majority of them are still the first time. If it weren't for the fact that it was within a strong wall. It is still surrounded by powerful heavy machine guns and a solid supply of ammunition. At the same time, there are also the 500,000 comrades-in-arms who fought side by side. I'm afraid that some of these recruits will drop their chains in this kind of scene.

But in fact, although I didn't see anything in the battle just now, in fact, there are not a few recruits who have dropped the chain, and when the recruits who faced this massive number of zombies were holding heavy machine guns, many of them opened fire with their eyes closed. If it weren't for the fact that the number of heavy machine guns firing at the same time was too many. It is likely that the number of zombies that break through the machine gun defenses and climb will be more.

Compared to the cheers of the human soldiers, the 400,000 zombie soldiers were extremely calm. For these intelligent zombies. When they were first created, they were fed with the memories of veterans who had been on the battlefield for a long time. So for these zombie soldiers. This kind of petty fights really isn't worth the excitement once.

Just like the zombie soldiers at the front line, just such a small victory could not arouse Hailin's excitement, and even there was no special notice to the liberators of the West Bank base, such a small victory was just a general account to send back to the base.

The attack of 500,000 zombies is just a temptation, and the brood area has experienced a year and six months of continuous accumulation of strength in the last days, and now it has become rich. The climbing zombies that originally belonged to the technical arms on the battlefield have now become cannon fodder. This had to make Hailin think deeply. This time the zombie attack is even crazier than ever.

In fact, there is another point that Hailin and even the entire Berlin Lake base do not know. In addition to the Spanish brood area, in fact, many important places on the continent today are home to brood cities that used to be hidden. The appearance of these brood cities makes it easier for the zombies to replenish their forces. The offensive trend will be more fierce in the future.

……

On June 21, the second year of the last days, after yesterday's temptation, the command zombies in the sea of zombies who attacked the Berlin Lake base system knew. The defenses of the two positions are almost identical. Therefore, it is no longer wise to attack two bases at the same time. Concentrate forces to attack one place, and if there is a tendency to transfer troops in another place, it will turn around and attack directly.

It's almost the same strategy as the Zerg attacking the border strongholds of the Buddha Alliance. Respond to all changes with the same, and drive the human side to divide the army with heavy troops. A bloodless conspiracy.

Compared to the border stronghold of the Buddha Domain Alliance. The border strongholds of the Berlin Lake base system are better guarded. This is because the span of the two canyons that enter the Bolin Plain is not very large. Therefore, it takes three million soldiers to defend the stronghold of the Buddha Domain Alliance's border pass. The follow-up increase in troops also needs to reach 10 million, but the border stronghold guarding the Berlin Lake base system only needs 500,000. And these 500,000 soldiers still don't need to all climb the walls together.

It's okay to work in three shifts. As much as possible to call the soldier a maximum state of mind to meet the battle.

Of course, in addition to the front-line combat units, the logistics troops are also very important. For the garrison of these half a million. But there are still 100,000 logistics troops. There are also hundreds of thousands of rear workers who serve these 500,000 soldiers day and night, and the soldiers of a stronghold. The situation is more or less the same in the other bases. So although it seems that there are many people available at the entire Berlin Lake base, it is actually not like that. Nowadays, even a large number of zombie soldiers are produced every day. But the people available in the hands of the freers. The available forces are still stretched.

……

"Oh my God. How many zombies must be there! "Experienced yesterday's victory. The soldiers of the 13th Army on the front line obviously have undergone some qualitative transformation. But the main force of today's zombies that followed was once again directly regretted the psychological defense line of these soldiers. Some of the soldiers even trembled a little when they spoke. The hands and feet were trembling incessantly.

A dense sea of zombies. More than yesterday. Endless. Boundless. They move slowly, but they are extremely oppressive. That kind of came slowly. Slowness mixed with self-confidence can ruin the feeling of miè qiē.

The first part is the giant zombies, and the difference from the previous giant zombies is that it is only a row, but this time the giant zombies sent out by the zombie side are more than one row. There are at least hundreds of rows of densely packed ones. The number of giant zombies has increased, and their size is also bigger than ever. In the past, the height of giant zombies was about five meters, but the number of giant zombies in this attack base has reached an average of seven meters, and some huge ones have even exceeded eight meters.

There doesn't seem to be anything in front of these giant zombies. But behind him is a slowly fat thirty. One by one, they clinged to the giant zombies like parasites, and slowly advanced towards the first stronghold of the Berlin Lake Base as the giant zombies slowly advanced.

"Fire on the fifteenth floor!" Hailin's order came. The human soldiers on the top floor of the border stronghold simultaneously pulled the trigger of their heavy machine guns. The heavy machine gun loaded with the chain of Dam machine gun bullets instantly erupted into an angry fiery snake.

"Dada...... Dadada......"

Due to the height of the fifteenth floor, the heavy machine gun on it can shoot the farthest distance. In order to test the defense of these giant zombies. Hailin gave the order to shoot first to test it.

The result was just as Hailin envisioned. Even with dummmy rounds, the heavy machine gun still struggled to break through the dense defenses of the giant zombie surface. A dummy bullet is not an armor-piercing round. Only when the dummy bullet attacks into the body of the zombie can the warhead open and produce huge destructive power, but if the bullet can't enter the body of the giant zombie, it can't inflict great damage on the giant zombie.

The heavy machine gun ate deflated Hailin and was not discouraged. In fact, after studying the corpses of the captured giant zombies in the base, the results also showed that the defense of these big men was even better than that of some second-order corpse kings. Zombies with pure defense, after sacrificing most of their movement speed, attack speed, and even reaction speed, are exchanged for a mutated zombie whose pure defense can surpass that of the second-order corpse king. If this kind of zombie rushes into the crowd, it will cause great damage to the crowd. Its thick arms and body can cause huge casualties when they walk by.

But again, if there are few people, and the survivors are calm enough. Giant zombies can't even attack a normal human, because their speed is so slow, and the process of bending down is enough for some agile humans to dodge.

"Mortar positions. Incendiary bombs. Carpet bomb the giant zombie camp! Hailin gave the order in a sonorous voice in the rear headquarters.

"Molotov cocktails, targets, giant zombie camps ahead. Launch! "The forward mortar position immediately launched an attack on the giant zombie camp at the same time as receiving the order from Hailin to attack. Unlike most of the people guarding the walls below are zombie soldiers or human recruits. At the top of the city wall was a mortar division composed of veterans of the 13th Army. The vast majority of them took part in the battle to regain the seven cities of Lake Berlin, and a few also took part in the battle to regain Italy. Although at the time of the battle to regain the seven cities, the Berlin Lake base still did not have such a powerful logistics industrial system. Most of the weapons used were cold weapons, but at least they experienced that period of close combat. These people are the elite troops in the 13th Army of Europe today. Compared to those soldiers who had guns as soon as they joined the army, more of them had the kind of blood that recruits rarely had.

As artillerymen. Although they are only mortars, they cannot open fire at will. It takes orders from higher to open fire in a unified manner, and one or two mortars don't play much of a role in such a sea of corpses...... Only that kind of intensive bombardment can cause great damage to zombies.

Order. The soldiers on the city walls, who were already gearing up, took out the incendiary bombs from the ammunition boxes around them. Reload. Put!

"Boom, boom, boom!" For a time, except for the sound of machine guns. Outside the stronghold, there was another loud explosion. With the sound of a huge explosion, the flames rose to the ground. Early in the morning, the soldiers on the lower floors had already been notified, and the firing ports were covered with steel plates. But even so, the soldiers inside the city walls instantly felt a scorching wave coming. And this scorching wave is getting more and more unbearable as it goes down. But fortunately, at the bottom are all hard-working zombie soldiers.

"Roar, roar, roar...... Roar...... "Giant zombies, although the ontology defense is extremely perverted. But after all, there is no need for those real corpse kings, and their huge defense power is mostly concentrated on the surface of the body. Internally, however, it is correspondingly much more fragile. Flames are terrifying to giant zombies, as they can quickly scorch their inside, even though their skin is intact.

The rugged and terrifying roar of fear characteristic of giant zombies came instantly. The soldiers on the human side were overjoyed when they heard this corpse roar. But not yet, their joy is widened. The mutation is happening again.

"The fire is out, the fire is out" The soldiers at the office observation posts built on the cliffs on both sides of the flanks sent back the message to the rear and mortar positions in a timely manner when the forward surveillance equipment could not provide an accurate impact in such a situation. When he heard that the flames of the incendiary bomb had just ignited and was about to be extinguished, the expression on the face of the commander of the mortar division, who had a hideous smile on his face, froze instantly.

"Second round, put!" This division commander can be regarded as a person who has seen a big scene. Knowing that the flames were about to be extinguished, he did not hesitate to give the order to continue the bombing.

"Boom, boom, boom!" Another round of mortars bombarded the camp of the giant zombies. This time, however, the explosion of the hideous slapping shell did not set off a monstrous flame again. The original flame was quickly extinguished. Once again, the cliff observation post gave accurate information.

"Fat zombies? A bunch of nasty guys. Hailin, who was located in the rear, looked directly at the screen and saw the situation around the giant zombie, muttering to himself while the fierce light in his eyes gradually emerged.

"Fat zombies? A bunch of nasty guys. Hailin, who was located in the rear, looked directly at the screen and saw the situation around the giant zombie, muttering to himself while the fierce light in his eyes gradually emerged.

"Forward observation posts transmit coordinates to heavy artillery positions in the rear. Liquid Nitrogen Bomb Attack. ”

For the kind of fat zombies that can extinguish fires, the Berlin Lake base has developed liquid nitrogen shells early to deal with it. Although fat zombies can extinguish fires. But they are virtually defenseless for extremely low temperatures.

In addition to being lethal to fat zombies, liquid nitrogen cannonballs have tremendous lethality to almost all zombie types. Although his lethality is inferior to that of human incendiary bombs, it still does not change its powerful nature. If it weren't for the limited production of the liquid nitrogen plant inside the Berlin Lake base, this shell would even become the mainstream of the battlefield.

Hailin gave an order. Forward observation posts and heavy artillery positions were immediately ordered. After a lot of observations, the facility calculated the location of the giant zombie formation. The forward observation posts immediately transmitted the information they received to the heavy artillery positions in the rear.

The heavy artillery position was located behind the seventh wall of the first frontier stronghold. There is still a long way to go from the front line, but the 205mm caliber heavy howitzer must be placed a little further back.

The commander-in-chief of the artillery position, who had obtained the coordinates of the zombies' location, immediately gave the order. All heavy artillery reloads.

"Click...... "......Click, click

"Reload the Elements!"

"Put!"

"Boom, boom, boom! Boom ......" Suddenly, the front of the world was discolored, and the entire heaven and earth were squeezed by the huge sound of the 205mm heavy cannon.

Far more than the firing from mortar positions. The power of the heavy artillery is not the liquid nitrogen shell that is known for its explosion, but even the power displayed in this way is terrifying to the soldiers on the front line.

The huge tremor made the soldiers inside the city wall feel the huge shaking of the city wall. At this time, more soldiers were vomiting and dizzy. It was a huge explosion that shook it. The smell of gunpowder from the machine guns and the smell of blood in the air were the result of a combination.

After the liquid nitrogen cannonball exploded in the giant zombie, the wrinkled body of the fat zombie clinging to the giant zombie immediately stiffened. The rapid low temperature instantly destroyed many of the secretion systems in the fat corpse. The secretory substance in the air, which could withstand the flames, stopped secreting in an instant. And with the passage of time, it is rapidly decreasing.

The body of the giant zombie was the same as that of the fat zombie, and it stiffened instantly. But the obvious giant zombie's ability to resist the cold is far greater than that of the fat zombie. The moment the liquid nitrogen shell exploded, the fat zombies that clinged to the giant zombies were already dead. But the life of the giant zombie is still not over. After a brief period of stiffness. The giant zombies moved slowly again, but this time their movements were stiffer than before. Half of them were covered in ice ballast, almost like icemen.

"These monsters!" With the help of binoculars, the soldiers at the frontier cliff observation post found that these giant zombies were still moving, and they couldn't help but feel a chill in their hearts. The explosion of a liquid nitrogen shell can instantly reduce the temperature within a certain radius to minus 100 degrees. But at this temperature, these giant zombies are still dying. This has to reflect the perversion of these guys from the side.

"Hmph. Immortal! I think they don't have the heat. Molotov cocktails! Put! "Compared with the small stock of liquid nitrogen shells, the number of incendiary bombs prepared by the 13th Army of Europe is large. If only there were no fat zombies. Hailin even tried to directly use flames to repel hundreds of millions of zombies. But that scenario is unrealistic after all.

But at this time, it is no problem to destroy these giant zombies in front of them with incendiary bombs.

"Mortar positions. Heavy artillery positions, all incendiary. Put! ”

"Boom, boom, boom! Boom, boom, boom, boom......, "For a while, the entire front line was filled with monstrous fire.

The moment the fire appeared, there was no huge roar of corpses on the entire battlefield, and it was because the previous liquid nitrogen shells had frozen all the vocal cords of the giant zombies. And the fat zombies are all dead.

Huge flames rose from the ground, soaring dozens of meters above the ground. The soldiers inside the entire city wall felt as if they had been roasted in a furnace.

......The aqueduct located above the city walls was prepared for this time. Whether it is inside the city wall or at the front of the city wall, the water curtain is as low as possible to reduce the temperature inside the city wall. Otherwise, excessively high temperatures are not only harmful to the soldier's body,. The prolonged heat may make the soldiers dizzy and their combat effectiveness greatly reduced. What's more, the blazing heat can easily cause safety hazards, and you must know that there are a lot of ammunition piled up inside the city walls. Once these munitions are detonated from the inside by high temperatures, they will cause heavy losses.

The air seemed to be burning. Many human soldiers and zombie soldiers have already taken off their military uniforms within the city walls, shirtless, sweating and holding machine guns.

The raging fire blocked the zombies behind, and although it was extremely difficult for the human side, it was the zombie side that suffered more losses. Giant zombies are not as scarce as they were when they first appeared. However, the zombie side did not know the information of the liquid nitrogen shells here in the 13th Army, so that the nearly 100,000 giant zombies and 500,000 fat zombies that were organized to attack this time were all wiped out. The mortar position was not far away, but the liquid nitrogen shells and incendiary grenades fired by the heavy artillery positions in the rear were enough to cover most of the area of the 100,000 giant zombies. The fire burned for an hour. An hour later, when the flames were decreasing, another round of incendiary bombs returned.

The giant zombies that were dying in the flames finally took their last breath under the attack of this round of incendiary bombs. Fell to the ground and quietly spent the last stage of his zombie life. Burn.

The liquid nitrogen shells of the 13th Army of Europe obviously exceeded the expectations of the zombie side, and the lack of intelligence made the zombie side lose 100,000 giant zombies in the first battle, just such an attack made them lose one-third of the giant zombies in this wave of zombie corpses.
