As for Ma Yi, the reason why he stands on the side of the female corpse king, revenge is only one aspect, on the other hand, he has to take into account the war damage of the human race, no matter who wins in the end, Ma Yi still doesn't want to see the human side lose too much, if every battle, the human race will be wiped out partly, then in the future, the human race will really disappear from this world.

Therefore, Ma Yi made a suggestion to the female corpse king, which is to first carry out a tentative attack, seize the opportunity to quickly advance a wave, and then attack to occupy the city wall, and then dispatch high-end combat power to carry out a high-level decisive battle.

At two o'clock in the morning, the human side was already a little impatient, and although Ma Yi was far away, he could see the tired eyes of the combatants on the city wall, and the high concentration made them destroy their willpower step by step.

Dozens of pitch-black C-type zombies stuck to the ground, like arrows off the string, rushing towards the protective troops outside the city wall, Ma Yi sat on the branch of a big tree, he could clearly see that the C-type zombies had approached a distance of three hundred meters, and the personnel on the opposite side had not reacted at all.

There are still two hundred meters, although several defenders are very disciplined and waiting, but still yawn, patted their faces with their hands, and kept themselves in spirit, some defenders who have had records and meritorious deeds, with cigarettes in the corners of their mouths, the stimulation of nicotine made them feel a lot more energetic, at least they were able to sober up for a while, and some people were silently rubbing weapons, all kinds of knives, guns, axes, hammers, although the types of weapons were more messy, but the shiny weapons showed that their owners often took care of them, after all, in the last days, Sometimes weapons are life.

One hundred meters, the observation team on the city wall suddenly turned their faces, their eyes showed doubts, and then their pupils began to contract, and then they raised the signal gun in front of them in a panic, and after their eyes were confirmed again, they hurriedly pulled the trigger, and the red signal flare flew into the air at a height of hundreds of meters with a whistle, and all the personnel were stunned, and then they all cheered up and looked into the distance.

"Fire." The Heavy hadn't yet spotted where the enemy was, but the red flare gun meant that the enemy had attacked, and the dense trajectory cut white chains in the night. At this time, the C-type zombies were only a short twenty meters away from the defensive position, and a few unlucky ones were directly hit by machine guns, first beaten to the body, and then slowly broken into pieces under the continuous bombardment of bullets.

The defensive evolutionaries all got up the moment the machine guns fired, and approached the Heavy one after another, forming an arc of defensive formations to protect the Heavy from being killed in the first place, and also to give the other backup Heavy time to change the guard after the Heavy was killed.

The claws of the Type C zombie and various weapons sparked, and when the blow missed, the Type C zombie turned around and attacked the evolutionary team.

The sound of machine guns rang out for nearly thirty seconds, and the machine gunners realized that there were no follow-up troops behind them, and just as they hesitated, several extremely fast black shadows rushed over again, and the machine guns rang out here.

Ma Yi can accurately see that almost all the machine guns are lit up in an instant, these troops are elites, in an instant, everyone fired at the moment when the flare was raised, but in some places, there were actually no zombies to attack at all, just reflexively fired.

Although men like weapons, Ma Yi has little research on weapons, and based on his life experience, he has not yet reached the point where he has leisure time to study weapons. It's like when he first entered the villa area to live, all the luxury cars all over the ground failed to arouse his interest, he didn't study cars at all, in his eyes, there are only two kinds of cars, common and uncommon.

The zombies launched three waves of sudden movements before and after, causing at least thirty heavy machine guns to consume a lot of ammunition, and the ordinary zombies behind gradually came to a position five hundred meters away from the defensive position under the cover of night, quietly waiting for the order of the female corpse king.

When the last heavy machine gun also stopped, the mighty zombie army began to run, hundreds of thousands of zombies acted together, the ground was making a slight vibration, and the machine gunners in the machine gun position saw the red signal flares on the city wall that were constantly being driven into the air for the first time, and the zombies attacked in an all-round way.

The sudden sound of machine guns sounded again, and when arming, each machine gun was equipped with less than ten base ammunition, and for them, ten base numbers could ensure that they could hold their positions within half an hour. In fact, for various reasons of uncertainty, ten base ammunition may not last half an hour.

The barrel is the most important thing of a machine gun, and if used for a long time, it will cause the barrel to become red and soft, and if it is dangerous, it will explode, and the heavy machine gun will be scrapped.

Rows of zombies swept over the white chains as if they were mowed, and fell to the ground, and then they were trampled by the follow-up zombies at a distance of 500 meters, even if there were dozens of white chains crossing strafing, they were still shrinking.

At a distance of three hundred meters, the automatic anti-aircraft machine guns on the city wall have been in full array, and dozens of base ammunition are neatly put aside, this time the base has almost all the anti-aircraft machine gun ammunition moved out, ensuring that the six anti-aircraft machine guns can achieve maximum lethality in the shortest possible time, and now the distance is still a little far, at least wait for these zombies to reach a position of one hundred meters or even closer.

In Ma Yi's eyes, as long as he is obedient and sensible, whether it is a zombie or a human, he has no bad feelings, but now he sees thousands of zombies being smashed into pieces by bullets in a few minutes, and his heart is still inexplicably uncomfortable, especially when he understands that zombies may evolve into a new species.

He tried to stop it, but the female corpse king disagreed, after all, he was just a passerby, and he didn't want to go too far and try to control everyone or zombies.

The machine-gun positions gradually fell silent after twenty minutes. Some of them were because the ammunition was consumed by the constant firing, and some were because the barrel had turned red and softened, and for a while, all the evolutionaries were ready for hand-to-hand combat.

In the ordinary zombies mixed with a certain number of D-type and C-type zombies, to face the relatively powerful masters of the human evolutionaries, ordinary zombies are much stronger than the first-level evolutionaries of humans and D1 and C1 are much stronger than the second-level evolutionaries, only the evolutionaries close to the third-level can initially contend with them, as for D2 If you fight alone, you must also have at least a fourth-level evolutionary, depending on the number of people, the third-level evolutionary is also possible. In the same way, D5-level zombies need at least three level 6 evolutionaries to compete, which is still considering that humans have rich combat skills and are very skilled in cooperating.

The zombies are not suppressed by the machine guns, and now they are beginning to rush over quickly, and the evolutionaries are constantly retreating regularly like the position of the city gate, after all, there are tens of thousands of evolutionaries outside the city wall, if they don't gather at the gate, after the battle, there is no time to retreat to the base.

Swords and claws are intertwined and fought together, zombies are not afraid of death, as long as humans are caught and bitten by zombies, they are destined to be infected, so they are also sacrificing their lives for righteousness, and the attack is twice as strong as when they are not injured.

Human beings are fighting while retreating, some people are obviously constantly speeding up in the process of retreating, and the people at the front, even if the protection on their bodies is relatively tight, is still a little not enough in front of a steady stream of zombies, if you cut down two, there will be four squeezed over.

The anti-aircraft machine gun fired, and the rattling bullet casings fell from the chamber of the gun invariably, and the six anti-aircraft machine guns cut off a piece of the zombie group dozens of meters away in front of the city gate, and the zombies outside could not enter, and the zombies inside were not enough for the evolutionary to kill.

After the zombies that were cut out were quickly eliminated, the anti-aircraft machine guns ceased fire, and when the zombies surrounded them, they continued to fire and cut off small pieces of zombies from the large zombie herd to ensure that the zombies and the evolutionaries had a certain contrast.

"I'll go, this machine gun is amazing." Ma Yi had now stood up from the branches, staring at the machine gun that was constantly spraying bullets and rain. Although it is not as shocking as Gatling in the movie, the two barrels are also constantly spitting out half-meter-long flames, and the bullets are connected in a line in the flames to sweep through the zombie group, and the powerful bullets of the condescending machine gun directly pierce the ordinary zombies from the head to the back, and the power is many times more powerful than the fire stick in the previous machine gun position.

"The zombies can't attack at all, but this thing spits bullets too fast, so it shouldn't last long." Ma Yi looked at the bullet casings that fell in a hurry, more than a dozen bullet casings fell in this second, and it was not a thousand bullets in that minute, so how much ammunition was prepared on the southern base.

Compared with the southern base, a small base like the Changfeng base is really pitiful, at least the Tongshan base still has hot weapons, and the Changfeng base is all about physical defense, Ma Yi actually doesn't know, the southern base used to be a military region near here, and it was daily live-fire training, so if it is a conventional weapon, their bullet base is still quite a lot, but there are many fewer heavy weapons.

The female corpse king couldn't see her impatience at all, she didn't have any expression in the face of the killing of her subordinates, it was only less than an hour of fighting, and the zombies died at least more than fifty or sixty thousand, and it was obvious that the ground was one layer higher than dozens of meters outside the city wall, and as time went by, the closer to the city wall, the more zombies were killed and injured, and the ground was getting higher and higher.

In the heart of the female corpse king, as long as this base is knocked down, then he can replenish a lot of troops, and the remaining subordinates can also improve their strength to the next level, which is a good choice.

"Give me all back, all back into the city." The commander on the city wall began to shout, and the defenders outside the city, after receiving the order, began to gradually retreat towards the gate of the base, and the troops closest to the gate turned directly into the city. Two machine-gun positions, guarded on both sides of the gate, were ready to fire at any moment.

A few C3s were mixed in the ordinary zombie group, and began to gradually get closer, and the flexible C3 was ordered by the female corpse king to avoid ballistic contact with the high-speed machine gun as much as possible, and it was easy to be encircled in the area that was divided.

"It's a high-level ghost!" Someone saw a black shadow flashing, and four or five companions were standing beside him, so frightened that his bladder tightened, and he almost peed his pants, and hurriedly shouted to remind his team to pay attention.

The person who shouted, as soon as the words fell, he felt that his neck was hot, and a bloody arrow from a meter away spurted out of his throat, and his breath couldn't keep up, and he fell to the ground and convulsed continuously.

"Quick, high-level ghost." Guardians continue to find traces of C3, but C3 is too fast for them to fight.

Several evolutionaries jumped down from the forty-meter-high city wall and rushed towards the area where C3 was located, but as they were running, the heads of the two people flew out of their bodies.

"Retreat, more than one." The evolutionaries all widened their eyes, looking at the two C3 that appeared again, their eyes were full of fear, if the D3 zombie level 4 evolutionaries could be besieged and killed, C3 would require at least several level 5 evolutionaries to be fully armed to surround and kill, the reason is very simple, this guy is too fast, and the attack is also sharp, and if you don't pay attention, you will be scratched and infected.

"Tianfu Squad, Tianliang Squad, Tianji Squad, you go down, the other three groups observe the battlefield and support at any time." The commander looked at the several teams standing behind him, this is the most famous Southern Dipper Six Star squad in the city defense army, they are all elites in the army, and all the team members are level five evolutionaries.

"Yes." Each of the three squads is six people, and the title also corresponds to the Six Stars of the Southern Dipper, eighteen fifth-level evolutionaries, jumped from the city wall, compared to the several fourth-level evolutionaries just now, they landed like cannonballs, and these eighteen people seemed light.

"A fifth-level evolutionary?" Ma Yi watched more than a dozen people jump from the city wall, compared to the people who jumped down just now, under Ma Yi's perception, they were obviously much stronger than those who could throw out the slash just now.

There are many new faces on the city wall now, there are young people, middle-aged people, and two old people, in their bodies, Ma Yi feels much stronger than the dozen people who just jumped down.

"The one above is a sixth-level evolutionary? It's not a big base, and there are still a lot of sixth-level evolutionaries. After Ma Yi sensed the strength of these people, he casually swept the city wall, and found that there were no less than twenty sixth-level evolutionaries on the city wall, and there were hundreds of fifth-level evolutionaries, with a reference, Ma Yi felt that the eldest brother Xu Qiang was actually a fifth-level evolutionary, it seems that the southern base has cultivated talents in a short period of time, otherwise with Xu Qiang's strength, when he went to the Changfeng base, he would not have discussed so kindly, and he would have killed the three giants of the base directly. Sending a fifth-level evolutionary to sit in a small base is not much stronger than a fourth-level evolutionary.
