"Order the posts to hold their defensive positions and not to panic."

"Turn on all searchlights and leave no dead spots behind."

"The second echelon is always ready to fill the defensive gap, and those monsters must not be allowed to rush in."

Xu Renjie gave instructions in an orderly manner. Under his orders, the airship and the ground forces reached a near-tacit cooperation. A large number of aerial bombs were constantly dropped, tearing through the dense formation of mutant creatures. Although they kept rushing towards the walls, they could not dodge the dense barrage of barrage. The towers, the top of the walls, and the searchlights in the sky illuminated the night as bright as day, and there was no cover around, so they could only rely on their speed and the bodies of their companions in front of them, roaring towards the sturdy and tall protective walls.

A burly pig-like humanoid with his head in his hands, fearlessly rushed through the machine-gun blockade, with bloody bullet holes all over his body, and rushed towards the city wall with the most strength and inertia. The moment the thick pig nose and forehead touched the wall, dense blood splattered in all directions. The force was extremely powerful, and the impact force was measured in tons. The ceramic layer on the wall suddenly cracked. Under the cover of the pigmen's massive bodies, a group of agile small gecko people immediately jumped up and pounced on the two nearest machine gun towers with dizzying movements.

According to Su Hao's suggestion in the document, Xu Renjie equipped each firepower point with at least two fighters. They immediately swung their tomahawks and knives and slammed into the gecko humanoids that swooped down in the air. The violent high-speed impact caused the carbon tomahawk to exert its amazing power, breaking open the gecko man's forehead without hindrance, and splitting the entire humanoid in half from the middle.

There are just too many of them. Although a few fighters were strong, they couldn't take care of them all. Several gecko men took advantage of the chaos to pop out sticky tongues, wrapping the soldiers at the machine gun control from the side, dragging them away from behind the mounts and throwing them into the air, throwing them out of the city walls.

"Fill the empty space right away, strengthen the defensive line of the fighters, quickly"

One of the captains roared, slicing a humanoid neck with his tomahawk. Nearby, a corporal quickly stepped over the still convulsing humanoid corpse and rushed into the gun mount, and the heavy machine gun, which had just been silent, immediately resumed its sharp roaring fire.

The degree of evolution of mutated organisms has far exceeded that of the same period last year.

A giant humanoid with the characteristics of a bull and seven or eight meters tall rushed out of the darkness. It grabbed a dead bloody corpse in front of it as a meat shield, roared, and strode toward the walls at a terrifying speed. The bull man raised his fists and smashed them against the hard wall, his fists covered with black thick hair were full of strength, and they were no weaker than the third-order strengtheners in the most exuberant period. Although a dozen or so defenders quickly turned their guns and fired straight at the bottom of the city walls, they still couldn't stop the bullmen's frantic movements. Its face was contorted, and it was clearly furious. The bullets that burrowed into its body caused it to feel so much pain that it could only roar and slam its horns against the wall, smashing bricks from the wall.

A large number of frogmen still gathered near the city gates, spitting out sticky acid. Thanks to the battle report of the Xinlan side in response to the "moon tide", Xu Renjie added anti-corrosion coatings to the surface of all the city walls in the new Chengdu base city. The thick green slime had no effect at all, but the dense cluster of frogmen became the target of the airship's attention, and was hit by a flying bomb falling from the sky, killing and wounding heavily.

A cold night breeze blew, dispelling the restless frenzy in Xu Renjie's heart, and the red face with boiling blood gradually calmed down.

So far, the battle has gone well. Although the number of mutated creatures besieging the base city is large, it is hindered by the defense power set up at multiple levels, and it is impossible to break through the city defenses. If this continues, we might be able to wipe out all of these guys.

Just when Xu Renjie's tense face slowed down slightly, the adjutant came over from the side and said in a slightly nervous tone: "General, the airship unit reported that they ran out of ammunition and requested to evacuate the battlefield and go to the airport to replenish. ”

"Order the fighter brigade to launch an attack on the subsequent swarm of mutant creatures."

Xu Renjie's eyes flickered, and he kept injecting the direction of the south, where the battle was most intense, and there was a trace of anxiety in his voice: "Tell the defense troops in front of you, don't mess up." We still have laser emitters that we don't use, and it's completely possible to hold the position. ”

Southern ramparts, Fortress No. 37.

It is a type of concealed fortress set up inside the city wall and almost flush with the ground at a height. With the mechanical operation of the inside of the wall, a rectangular perforation of 20 centimeters high and 50 centimeters wide appeared on the wall, which was thirty centimeters above the ground. Just in the deepest part of the perforation, there was a faint glimmer of light.

Due to the non-proliferation nature of high-energy rays, the laser emitter does not need to have too large an emission boundary, and the firing angle of fifty centimeters is enough to cause a large area of damage. In order to ensure the stability of the walls, the fort itself was extremely strong, and the interior was filled with steel plates up to several centimeters thick. In this case, the operator can only observe through a monitoring probe at the top of the city wall, or through an on-board monitoring device. Once the laser is fully charged, it can release a death ray with a strafing area of 60 degrees by manually entering the coordinates.

In order to ensure the effectiveness of the attack, two lasers set up near the southern gate will fire at the same time. As long as the light sweeps through, it can deal at least fifty percent damage to mutated creatures on the entire defensive surface.

Just as the air shield was slowly opened, and the operator was scanning and positioning the laser emission boundary, several slender black shadows suddenly jumped in from the outside of the narrow perforation. They pounced on the operating officer like ghosts, and a terrible scream rang out in the fortress.

"Oh my god they're in, help, help"

A slender black shadow wrapped tightly around the operating officer like a noose. They struggled desperately, but they felt that their bodies were bitten by something sharp a few times, and the strengthened body could no longer produce force, and it was pitch black in front of them, and it became difficult to breathe. After only a few shouts, all the operators in the two fortresses collapsed one after another, completely losing their voice.

"What the hell is going on? Why don't you launch war lasers? ”

A few minutes later, a major with a dozen soldiers kicked open the fortress gate with a face full of rage. Just as the angry major was about to open his mouth to curse, he suddenly saw the dead body lying on the ground, and the black shadows coiled on the corpse and eating it.

Their heads are small, only the size of a fist, in the shape of an inverted triangle, with blackish-yellow mottled scales on the surface. The shape of the mouth and nose remains similar to that of a human, and sharp fangs protruding from the mouth that are more than 30 centimeters long. Under the light, you can see the thin fangs arranged in the flat lips, which makes you shudder.

This is a humanoid that has never been seen before and has a very low degree of evolution. Their bodies are still elongated, colorful and stretchable. But anyone who has seen them can easily recognize that they are terrifying mutants with snake genes.

The pupils in the Major's eyes constricted. He stared at the nearest serpentine man, and countless fearful and chaotic thoughts crossed his mind.

These snake people were unlike anything they'd seen before. They are small and nimble, allowing them to burrow into the city from any crevice. They are highly toxic, otherwise, it is impossible for all the operators in the fort to be killed in a short time. The most terrifying thing is that the fangs of these snake people stretch and retract freely, and they have also evolved canine teeth like beasts, which can tear and cut their prey.

Moving from a frightened state to an attack requires a brief mental gap for any creature. Despite the fact that the confrontation lasted no more than two seconds, the Major and the Snake Man were engaged in action almost simultaneously. The former wielded his battle axe and slashed at the snake man in front, while the latter's upper body shrank back slightly, and in a strange way with extremely strong flexion ability, his entire body was ejected towards the soldiers who broke into the fortress.

Humanoids are the product of the evolution of zombies. This is a fact that everyone knows.

Even in Su Hao's original time and space, no one knew what kind of snake people appeared later than other species?

Maybe it's because snakes need to hibernate in a special habit?

Or maybe they need to molt every time they grow?

But no one can deny that the smaller, agile snake-like humans do pose a threat that other humanoids can't match.

The battle axe in the Major's hand accurately severed the snake man's body. The moment the axe fell, the Major's throat was also bitten by the broken snake man's upper body. He let go of the axe, grabbed the snake man's head with both hands, and screamed loudly, pulling it down his throat. Then, staggering back and forth a few steps, he fell hard.

The soldiers shot at the snakemen who were rushing towards them. In a state of panic, this kind of shooting is not accurate, and the fear of the unknown greatly reduces their combat effectiveness. The snake man coiled around his comrades made it difficult for the soldiers to aim and unable to continue pulling the trigger. They retreated from the fort, running back to widen the range and shouting warnings in all directions.

The number of snake people is not large, only a dozen. But they have a devastating effect on soldiers and the fighting situation. The entire garrison near the city gate was suddenly thrown into chaos. Although several officers brought in flamethrowers and fought their way into the underground fortress and closed the laser emitter, the tide of the battle changed due to a brief disturbance.

Dense defensive fire makes it impossible for mutant creatures to break through the city. The fighter planes that succeeded the airship dropped bombs again, tearing apart the dense bio-frenzy. Just as the area near the city gate was gradually emptied, a large group of mutated creatures suddenly rushed out of the depths of darkness.

That's a giant humanoid with thousands of heads.

With an average height of over six meters, their massive bodies contain terrifying strength. Every time you move your legs and feet, you can step a distance of more than ten meters. Due to the weight of the body and the number of people, the ground was trampled by countless hooves and feet, and trembled slightly.

No one noticed exactly when the group of giant humanoids gathered. No sooner had they come into range than the searchlights were met with intense fire. The heads of the pigmen who rushed to the front were blown off the spot, and huge blood holes appeared in their chests and shoulders. Their bodies had not yet been crooked, and the other mega-humanoids following them had already grabbed them. Relying on this method of using the corpses of their companions as meat shields, the giant crowd quickly rushed to the bottom of the city walls. They swung the corpses in their hands sideways, raised their arms to cover each other, and under the dense inclination of bullets, quickly gathered the mutated creatures that died nearby, and piled up a mountain of corpses with a sloping slope at the bottom of the corner.

Seeing this scene, Xu Renjie only felt shocked, and his hands and feet were cold.

"They...... How did they evolve intelligence? How do you know how to cooperate with each other and use the terrain? ”

Without waiting for the thoughts in his mind to become completely clear, Xu Renjie grabbed the microphone of the communicator next to him and roared sharply in a thunderous voice: "All the defense troops pay attention, immediately concentrate on sealing the edge of the outer wall." The air force changed its tactics and immediately sent construction machinery to clear the outer city walls. ”

Before the words fell, Xu Renjie's worries had become a reality.

In the depths of darkness that cannot be seen through by the naked eye, tens of thousands of dog people, blood corpses, and cat people have poured out...... These agile mutant creatures followed closely behind the giant humanoids, along the mountain of corpses that had just piled up, and in a matter of seconds, they were already jumping up the city walls.

At night, the movement of mutated creatures is hidden. Their eyes reflect yellow-green fluorescence in the night, and many species have eerie vertical pupils. Although the fighting troops quickly picked up their weapons to meet them, they could not withstand the frenzy of tens of thousands of massive creatures at the same time.

A corporal roared and turned his machine gun and fired at the monster that had just pounced on the wall, only to be swept in front of him by a bloody corpse that leaped up along the wall, cutting off his head with his sharp forelimbs, and spurting a fountain of blood from the broken neck cavity.

A lieutenant slashed with two carbon battle axes and slashed five or six humanoids in a row. He rushed so far that he forgot to keep enough distance from his companion next to him. The spider-man lying on the edge of the wall immediately stared at him, and took advantage of his unpreparedness to spew out a stream of spider silk with a strong fishy smell, sticking to the lieutenant from behind, dragging him fiercely, and dragging him down from the top of the wall.

The top of the city wall, large enough for two heavy trucks to drive side by side, was soon filled with the corpses of humans and mutated creatures. Broken body fragments and shredded flesh were everywhere, and blood flowed from the corpses in a trickle, leaving along the walls, staining the entire wall red.

New Chengdu Base City, a civilian area.

Despite Xu Renjie's repeated orders to maintain order in the city, civilians were not allowed to go out during martial law hours without permission. However, due to the lack of supervisors, the guards deployed a large number of soldiers to support the battle at the southern gates, and the situation in the city still inevitably became chaotic.

"This is our best chance. Only once, and never a second time. ”

"What we have is people. As soon as they rush into the military control zone, there are large quantities of weapons and ammunition, and there is an endless supply of food and canned food. The trucks inside were all filled with gas, and all we had to do was rush in and drive them away

"Only the bravest can get rich. Snatch it up, and the cuckolds can't tell whose it is. Lao Tzu has long had enough of being ridden on the head and shit and pee. Listen to me, there is not only food and weapons in the military zone, but also fortifying potions. Do you want to be like this forever, to be an ordinary person who is called to drink? ”

There is no shortage of careerists among the common people. Even the most humble person has the idea of wanting to get on top by any means subconscious. The confrontation between the population and the military has existed since the early days of the virus outbreak. Under the high-pressure control, they have to curl up and lie dormant in fear of death. Now that most of the city's troops have been moved to the south, and the guards in the various control areas are sparsely populated, there is no better chance of fighting than now.

The riot first took place west of Base City.

A mob armed with sticks attacked several soldiers guarding the street. Despite the fact that the soldiers were fortified people, they were still deceived by the mob with rhetoric and were hacked to death on the spot when they were caught off guard. The thugs who got the guns became more and more frenzied, and the killing frenzy affected more and more people. Soon, the riots had spread to more than half of the city, and almost everyone was coerced into participating. They began to besiege the towers and checkpoints in the city, throwing Molotov cocktails at the various strongholds, and the sound of gunfire and explosions even overwhelmed the defensive sections of the southern wall.

In all fairness, not everyone wants to rebel. However, this is the case with the herd mentality of human beings. When the submissive people see the mob rushing up and killing the soldiers, taking the guns from the corpses, and getting military rations and all kinds of precious objects that are difficult to obtain in ordinary times, the ordinary psychology of thinking about being an honest person will suddenly be distorted in an instant.

Xu Renjie focused his defense on dealing with mutant creatures, and the armed forces responsible for controlling the city were naturally greatly reduced. Although the soldiers were able to fire at the rioters with the help of the guard towers, they were still terrified. Especially when the numerically superior thugs lay siege to the ground posts, beating their comrades to death with sticks and machetes, there is always a sense of helpless despair.

When the mob stormed the eastern outpost and looted a truck full of explosives, the situation in the city spiraled out of control.

A lunatic man who had been injected with a large amount of heroin and was extremely energetic got into the cab, and amid the cheers and cheers of many rioters, he stepped on the accelerator fiercely, drove the truck at high speed and rushed to the wall between the military control zone and the civilian area, and exploded a rift tens of meters long.

The dense crowd quickly sloped towards the breach of the wall. Tens of thousands of people poured in from the gap. Despite the desperate shooting of the nearby guard towers, they could not stop the frantic crowd. The road leading to the breach of the city wall was soon filled with civilians who had been shot and killed, but many more people used various equipment to block the bullets and ran wildly in the direction of the breach. They cursed the soldiers on the tower who shot at them, their minds filled with dreams of becoming fortified overnight. As soon as you are out of the shooting range, immediately throw away the obstacles in your hands, draw the knife from your back and waist, open your red eyes wide, and loot any property that is taken care of.
