On Earth, many creatures have natural enemies that are incompatible with them.

Just like cats and mice, mosquitoes, flies, spiders, frogs and various insects... This food chain that has evolved from ancient times to the present is the most fundamental comparison of the strength of organisms. They have existed since ancient times and will continue on a fixed trajectory.

Of course, lions can still eat mice and grasshoppers to survive. However, there are very few lions and never even disdain to do such things. Because the amount of meat in that bite is too small. Instead of wasting time and energy, it is better to continue to pursue zebras and catch antelope.

Of course, ants eat elephants, but that is not the main source of food for ants. Through factors such as region, species, quantity, and the size of organisms, the corresponding populations are gradually fixed on the earth, and then exist in the genes of each organism in a genetic form.

When mice see cats, birds will tremble when they see snakes, which has become a fixed biological instinct. Although parts can be erased through acquired training, just like bears and ducks performing on the same stage in a circus, in essence, they have become deeply rooted with the genetic genes and become an eternal imprint in the depths of thinking consciousness.

According to research in the future world, 70% of the mutated creatures entrenched in abandoned cities are infected with insect genes, 20% have genes for small mammals such as rats, cats, and dogs. The remaining 10% are mostly mutant zombies (storm corpses or mad corpses).

This data is actually not accurate. Among the different types of mutant creatures, there are actually many evolved individuals with complex genetic evolution. In the military archives, Su Hao has seen records of tiger people, lion people, deer people, and turtle people more than once. The reason for the emergence of these special individuals is nothing more than the abandoned city local zoos or feedlots. Especially in some fresh food supermarkets near the eastern coastal and mainland cities, crab people and fish people have even been found.

However, no one can deny that insect-type mutants account for the vast majority of them.

It is a very strange phenomenon that many monsters coexist in the city.

The Academy of Sciences has never been able to understand why cats and rats can sleep in the same room, but they will not bite and fight each other? In the 22nd year of the Black Age, a researcher tried to put feline pheromones in the cage that captured cats and rats, which triggered a fight between mutant creatures. The two cats and people lost six rats. The crazy monsters sat on the pile of corpses and chewed heavily, and finally ate until they died.

They are indeed natural enemies, and the instinct hidden deep in the gene chain has always existed. As for why it did not cause confusion before... the final research result of this by the Academy of Sciences is to understand it as "insufficient pheromones concentration."

Mutant creatures seem to know the importance of peaceful coexistence. In a narrow space, they will hide hostility from each other and reduce the release of hormones, thus creating a strange scene where wolves and little white rabbits live in the same room.

According to Su Hao's request, the "Nighthawk" helicopter deployed a large number of dragonflies, frogs and spider pheromones in the core area near the south of the city. These extremely high concentrations of hormones immediately caused chaos in the mutant creatures. Although the surrounding space was very narrow, it was not completely closed. In panic, the cockroaches, mosquitoes and flies mutants in an opposing position began to flee around. Because they all have population characteristics, they quickly gathered a huge number. Although other types of mutant creatures are not sensitive to pheromones, they are swept by the huge impact tide and run wildly towards the areas they think are safe.

When setting up the minefield, the search troops had followed Su Hao's orders to install explosives inside the tall buildings in the area, causing the buildings to collapse in the predetermined direction. When the road was completely closed, the area behind them was filled with powerful threats from natural enemies, and the mutant creatures naturally had the only passage directly in front of them.

"Fire———"

With Liu Jiangyuan giving the order to the microphone, in an instant, the rough and harsh and dense gunfire pierced the silence above the defense zone. The hundreds of machine gun positions spewed out flames, and the bullets flying through the air accurately hit the bodies of the mutant creatures, knocking them out of balance on the spot. While dense blood splashed in the air, they staggered and fell, turning over the large number of monsters that followed closely behind.

"Continue shooting and kill all these damn bastards———"

The direct aim guns set up at the top of the fortifications in the rear continuously fired shells, creating explosions and deaths in the depths of dense monster groups. The caliber of these guns is less than fifty millimeters. Even if firepower coverage is applied to a certain area, it is impossible to achieve an annihilation effect because the shells are insufficient. However, as a fixed defense device in the main direction, regardless of range or firepower, the threat to single targets is far greater than that of assault rifles.

The 517th Division has been besieging Lujiang County for several months. In order to strengthen its position, a large number of reinforced concrete fortifications with staggered heights were created around the highway. In addition to these, the roof of the nearby high-level building was also set up as a machine gun position. In order to achieve the best effect of this battle, Liu Jiangyuan transferred two infantry fighting vehicles brigades and arranged them along both sides of the kilometer base to block the mutant creatures' running wildly with fierce car cannons.

Su Hao formulated a very clever plan - in addition to burying explosives inside the building, the soldiers also set up more than 30 small sealed metal tanks in the neighboring blocks. These iron tanks have been opened in sequence according to the speed and time of the impact of the mutant creatures. The pheromone stored in the tubes quickly formed a spacious enough wall in the south of the city, which is tantamount to a "dead road" for the mutant creatures.

Yes, that is indeed a nearly fixed airflow.

In this hot season, there is usually no wind that is too strong. In addition to carrying canned pheromones, the helicopter also installed a high-power directional blower. The hormones that permeate the air are wrapped in the wind and enveloped the mutant creatures like poison. They have nowhere to escape, and are desperate in the sound of rolling cannons and gunshots, passing through the cracks of collapsed buildings. In the end, they can only follow the lines drawn by Su Hao on the map and escape to the outside of the city along the Central Avenue.

Su Hao did not release too many pheromones, nor did he release more species at the same time. The throwing location was not located in the core of the city, but was shifted south by 500 meters.

According to rough estimates, the number of mutated creatures gathered in this city has exceeded 100,000.

In the monsters' dictionary, there is no word "surrender". Of course, they do not want to die, but they have not been able to evolve corresponding wisdom.

The 517th Division has a limited number of troops and cannot strictly seal the entire city. Especially when a large number of heavy troops are equipped with a southern highway, the guardians in other directions will naturally be reduced to a certain extent.

"Separating the flow direction of the region" is a tactical term for the future world. Its meaning specifically refers to the separation of mutated organisms in a fixed area when there are too many mutated organisms in a fixed area and cannot be annihilated at one time, using light, sound waves, odors and other methods to separate mutated organisms, and reduce them in batches, and ultimately achieve the goal of complete annihilation.

Biological things are not machines. They have independent thinking consciousness. Even humans will follow most people in a fixed direction in panic and chaos.

Although, they themselves don't know if it's safe? Or is it leading to death?

The hundreds of meters long road is crowded with insect-type mutant creatures of various forms. They fly over the walls and principles, using their newly evolved hard wings to glide in the air. Several carapace-shaped humanoids had just jumped out of dozens of meters and landed on the ground. They were immediately trampled by the ants-shaped humanoids as stepping stones.

Looking at the dense red light spots representing mutant creatures on the electronic map, Liu Jiangyuan's pale face gradually showed a large flush on his pale face. He held the microphone tightly and stared at the humanoids and corpse people getting closer and closer. When these hideous and terrifying creatures continued to run forward in the rain of bullets and bullets, and then occupied almost the entire street, Liu Jiangyuan finally roared at the microphone with an unprecedented arousal and fierce look.

"Detonate————”

With the order transmitted by electronic signals, houses over 100 meters long on both sides of the highway exploded, and tens of thousands of dense steel balls and fragments shot out, completely blocking the entire street, forming a bloody path of hell covered with flesh and blood.

On this road, Su Hao arranged thousands of directional landmines.

These mines do not need to be buried, but are set in holes dug temporarily on the wall of the house. All mine detonation directions are adjusted to one side of the road, and they are demolished and detonated by electronic signals. Steel ball fragments flying in the fan can instantly cover the entire road, mercilessly colliding, cutting, and tearing between the blood and flesh.

In the biological wars in the future world, directional lightnings with metal fragments as the main killing method are used in large quantities. The energy radiation area they cause is not large, and the area generated by the explosion is small, but the fragments released are numerous and dense. Once triggered, they cannot be avoided at all.

The military strictly prohibits the use of large-scale energy explosion weapons, but does not regulate the fragment damage caused by directional lightning explosions.

These orders once puzzled Su Hao. He spent a lot of time studying and finally found specific implementation details from the military computer.

In fact, there is only one ban on the military headquarters——It is strictly forbidden to use energy weapons with destructive power exceeding 50 by 50 (meters) of the corresponding area.

The "destructive power" mentioned here refers to the effect of the explosion intensity being killed on the spot in the prescribed area with the ""-level mutant creatures as the standard. According to the explanation of military computers, the high-power lasers and electromagnetic cannons of linear attack are not within the prohibited range, and the metal fragment casualties caused by directional lightning are not listed here. Because the damage area of ​​the former is limited, it only affects single bodies and straight targets. Although the latter causes tablet injuries, it does not belong to the category of energy explosions. At best, it is just a chemical detonation within the controllable range.

There are many things that are literally obscure and difficult to understand. Only by actually operating them can you understand the specific functions.

The streets filled with mutant creatures, filled with strong impacts and roars, quickly became silent. Thousands of humanoids and corpses have turned into pieces. The mutant creatures located in the middle of the road have a light damage, but their flesh is still blown up, covered with wounds of all sizes. They struggled in the flesh of their kind or companions. The ground was covered with blood and flesh, and thick corpses were stacked layer by layer, nearly two meters above the ground. Some frog-shaped human bodies with special structures were cut open by shrapnel, and yellow-green pulp kept flowing out of the torn body. These liquids were obviously strongly acidic. When they flowed through the surfaces of other corpses and meat pieces, they always had a faint pungent smoke, burning out a terrible "hissing" sound.

A few minutes later, the tall wall of flesh and blood was pushed away from the inside, and as many as thousands of mutant creatures flocked out again. They had no interest in the fresh meat everywhere. Apart from escaping and staying away from this city as soon as possible, their simple minded brains had no extra thoughts.

Killing is getting easier.

The intersection was tightly blocked by machine guns and artillery, and the two-kilometer highway was equipped with up to tens of thousands of directional mines. The helicopters monitored the battle situation in the air and transmitted the number of mutated creatures in each section at any time. According to the congestion on the screen, Liu Jiangyuan ordered the detonation of mines on both sides of the highway in sections... In this way, under the continuous explosion and rain of bombs, tens of thousands of mutated creatures were unable to escape from the city. They were either bombed on the spot, torn apart by gun bullets, or crushed by collapsed houses, and died in the howling of fear.

The pointer on Su Hao's watch just ran through the 36th space.

There is no shadow of the mutant creature on the road. Looking around, the line of sight is full of blood and corpses, like a river filled with red liquid, and the corpses are floating islands flowing with the waves on the river surface.

The "Yeying" helicopter sent a signal that he was about to leave. The electronic screen was filled with blood mist, and only a few seriously injured and dying mutant creatures struggled among the ruins. The sun was still hanging in the sky, sprinkling hot arrows and light on the earth, as if satisfied with the bloody battle that had just ended. He planned to wait for the night to come and savor the stimulation and excitement in his sleep.

There was silence on the 517th Division's position.

Liu Jiangyuan slowly took off his oxygen mask and looked at the city with great shock with emotion.

He fought here for several months, and the cumulative mutant creatures he destroyed was no more than 12,000. As for the price he paid... several thousand casualties were killed or killed in the 517th Division, and he was almost forced to return to the Nanyang Base City to fully accept personnel supplements.

"It's only one day, one hour? No, not, it's only forty minutes at most. Look at how many we have eliminated? This is simply terrible. I never thought that there was such a way of fighting. Ten thousand, twenty thousand... No, there are at least thirty thousand heads here. A total of thirty thousand----"

The animal pheromones that are spreading in the air are gradually fading and cannot cause harm to the human body.

The position was covered with a thick layer of bullet shells, the heavy machine gun mounts near the armored combat vehicles had been replaced six times in a row, and empty ammunition boxes were piled up in the ring fortifications.

Liu Jiangyuan's actions quickly infected others.

Officers and soldiers kept taking off their oxygen masks and breathing in strong bloody air. They were shocked by the huge damage they caused in such a short time. Many people walked out of the fortifications and walked on the street with a confused and surprised expression, allowing the blood from the deep calves to soak the military boots, as if walking in the legendary Hell Blood River.

Huang He stood beside Su Hao, his eyes were straight, and his lips were shaking uncontrollably. Perhaps he wanted to use nicotine to drive away the chaos in his mind, Huang He took out a cigarette from his pocket, but he could not pinch it with his fingers. He finally stuffed one into his mouth, but while pulling the lighter, it fell from the crack of his lips.

No one has ever seen such a bloody or tragic scene except Su Hao.

This can no longer be considered a battle, but a massacre.

They have no brains and no wisdom, and rely on biological instincts to drill into the trap stupidly.

If it were humans, so many would not have died.

At least, humans will not encounter two explosions in the same trap.

But they are not, they are mutated creatures.

We are taking revenge, taking back our city, our home.

Huang He only felt that his thinking had become difficult, his face was so pale, and his eyes looking at Su Hao were filled with unprecedented worship and piety.

This is no longer the guiding effect of the black particles. Even if the Yellow River's identity is not a "working bee", his respect for Su Hao is indeed from the heart.

"This is simply terrible, it's incredible..."

Huang He gave up the idea of ​​continuing to stuff cigarettes into his mouth. He broke and crushed the other cigarette he had just gotten into his hand, and brought the infinite gratitude and excitement that the drowning person had just breathed the first breath of air. He lowered his head in great devout respectfully and asked in a obviously trembling tone: "Your Excellency, what should we do now?"

Only when there are no strangers next to you will the Yellow River use the honorific title "Your Excellency".

Su Hao stared at the sea of ​​corpses and blood in the distance, without looking back.

After a long time, he gave a light command: "Order the squadrons to collect crystal stones and silver bones as soon as possible. By the way, let the new recruits see the blood."

This is only the first battle.

If you want to truly regain this city, you have to continue to have at least two sieges of the same level.

An hour later, Adjutant Liu Jiangyuan, with several guards, invited Su Hao to attend the celebration dinner held at the division command center in an extremely humble and respectful tone.

It is said to be a dinner party, but it is actually a dinner party for middle and senior officers at the division level.

When Su Hao walked into the division command post accompanied by his adjutant, the crowd who had been waiting for a long time suddenly burst into extremely warm applause.

Liu Jiangyuan introduced Su Hao to all the officers, and everyone came forward to shake hands with him in sequence. People's eyes were filled with unconcealed enthusiasm, gratitude, admiration and respect. Only when they saw a strong man with enough strength would the soldiers give such unscathing etiquette, without falsehood and perfunctory etiquette.
