The 'Chirp Chirp' intelligent robot fired, quickly firing incendiary grenades from the rifle, and as the shells fired, the robot's arms could only raise their arms rhythmically. The intelligent robot's accurate computing power is undoubtedly exposed, because the grenade is a parabolic firing principle, so only the robot has been pulling the trigger, but none of the shells are connected to the burning range.

As the cannonballs fell, the zombies within the range of the cannonballs were instantly engulfed by the flames, and the zombies had no chance to react at all. Many zombies received the order of the mother body and were charging towards the base with human flesh, who would have thought that what was ushered in was a powerful incendiary bomb, and some of the zombies that fell in the middle were vaporized in an instant. When the temperature reaches 5,000 degrees Celsius, it can instantly vaporize the human body, and the three-meter central area of the super-concentrated solid gasoline bomb can instantly release a high temperature of 7,000 degrees, and the high temperature can reach 4,000 degrees within 20 meters, and at least 30,000 zombies are drowned in the fire, and they fall silently with the falling incendiary bomb.

"Twitter!!! The mother zombie let out a shocking high-frequency scream, and all the zombies also made an earth-shattering sound with the mother's shout.

(Master, the zombie mother body is summoning all the mothers within thirty kilometers, it is angry and scared, it is rescuing!) ）

(Damn, rescue with a face, is there a bit of morality!) ）

(The owner can rest assured that there are only two zombie mothers within thirty kilometers.) One is the parent body of the airport, which controls about 300,000 zombies, and the other is the prison matrix, an old friend of the owner, who currently only has more than 100,000 corpses. The owner can rest assured that the two zombie mothers themselves control relatively few corpses, and they should not pay attention to its pleas for help to support it, but may move out of this area! ）

(Huh?) Why? ）

(Master, I said that the zombie mother body is an intelligent and brain-like existence, do you think animals with intelligence and feelings will die in vain?) The millions of corpses controlled by these two mothers are all afraid, so isn't it useless for their hundreds of thousands, hundreds of thousands of corpses to come? Besides, the loss of the zombie mother body is equivalent to the big girl stripped naked and pouting her ass on the street! ）

(System, you've changed!) But I like your analogy! Liu Long thought with a lewd smile in his heart.

While chatting with the system, Liu Long also paid attention to the battle outside the base. The mother zombie lost three percent of its corpses at once, and it was enraged, and no human had ever been able to do such harm to it, because without exception, all of them were eaten by themselves. The zombie mother also needs human genes, and the more people the zombie mother eats, the stronger the intelligence will improve, and she can control other mothers to expand her team.

This mother body is obviously a zombie mother body that has undergone an evolution, and first ordered the zombie army to stand by by trembling, and a look of thought erupted in a pair of small eyes.

"Look, boss!" Xue Peng shouted at Liu Long, asking him to pay attention to the changes in the zombie army.

"Damn, what's this, decentralized attack?" Liu Long was also shocked when he saw the transformation of the zombie army, and the distance between all the zombies was about one meter, and they continued to rush towards the base.

"Don't these fools know that our incendiary bombs can only hit once? Isn't this kind of scattered attack a target, and zombies without a number as a base are not to be feared. Liu Long smiled and looked at the zombie's actions.

"Boss! It's true that we don't have incendiary bombs, but we still have all kinds of grenades and missiles fired by 81 rifles, and the scattered attack of zombies directly minimizes our artillery advantage! Xue Peng immediately reminded Liu Long who was in Silly Music next to him.

"I'm wiping it! You're right, the scattered corpses are not conducive to any of our artillery fire! Liu Long only understood the seriousness of the situation when he heard Xue Peng's reminder.

"Boss, we can only put the zombies close and use rifles to block them, but our ammunition is not very sufficient, only about 200,000 rounds." Xue Peng expressed his opinion and watched Liu Long wait for him to come up with an idea.

"Then let's get closer!" With Liu Long's order, the members who were originally going to block the artillery fire were replaced by rifles.

With the rapid advancement of the zombie group, it soon entered the firing range of the 81 rifle, and Xue Peng ordered to put the zombies into the city wall when there were still three hundred meters away from the city wall to block the attack!

"Fire!" Liu Long ordered.

The entire city wall, including the top of the wall, was divided into six layers, and after removing the top of the wall, there was a shooting hole every two meters in the wall of each floor. Because the wall is so thick, the shooting port is designed as a cone extending from the inside out, the innermost round hole is only the size of a cigarette box, while the round hole on the outer wall is a large round hole with a diameter of 40 centimeters. This way, the firing angle is not blocked, and the gunner can accurately aim at threats outside the wall.

On the three-meter city wall where the zombies attacked, fire snakes were sprayed everywhere, and the zombies were quickly killed by bullets one by one. The powerful penetrating power of the bullet directly hit the zombie's head, and the huge force made the fast-running zombie directly backwards. The zombies looked like a tragic scene of people turning over on their backs, and the zombie mothers in the distance were about to burst into fire when they saw it.

"Twitter!!" The mother zombie let out a loud and piercing roar again, and then its whole body trembled rapidly, as if it had given a very long series of signals.

(System, why does this matrix keep calling?) Also, why is this thing shaking like what's inside? Liu Long covered his ears and observed the zombie mother through the debugging of the electronic eye, Liu Long saw where the zombie mother body was five kilometers away and screamed, and shook his body at a high frequency.

(Master, the zombie mother seems to know that it can't summon rescue, it's summoning scattered zombies within 30 kilometers, and the mother's cry can only travel a distance of 30 kilometers, and this distance will change according to the barrier in the middle, but it can be determined that it is summoning wandering zombies.)

The zombie mother body commands the zombies through the high-frequency vibration of the whole body, and the length of the vibration time represents the length of the command order, it seems that the zombie mother body is directing the zombie army to deal with the current one-sided situation! ）

(One-sided?) Liu Long was stunned for a moment, then looked at the battlefield outside the base. The firepower of the members of the base suppressed the zombie army that had been beaten and retreated, and the army of the zombie mother body was afraid of the power of the incendiary bomb, and did not dare to use the tactics of the sea of people, so from the battlefield Liu Long had the advantage, the current blocking area has been blocked from the original 300 meters to 500 meters, the zombies can not rush in at all, and the blocking area of the guns is still expanding, it is estimated that the range of the blocking area will be expanded to the maximum range of 81 guns produced by the system is about 800 meters.
