The drone sent the latest footage of the front line of the battlefield, and the first line of Kuroshio swept towards the defense line of the base at a heart-wrenching speed.

"Searchlight running at full power!"

Zheng Xiao gave the first combat order.

Above the walls of the base, dozens of large-caliber laser searchlights suddenly lit up, and beams of white light tore through the darkness, reflecting the perimeter of the base as if it were day.

This order sounds redundant, and it will even deplete the energy reserves of the base. The soldiers were all equipped with night vision devices, and darkness did not affect their vision.

But when you think about it, it's necessary. Because the bright light from the searchlight will cause some trouble for the oncoming monsters, there are many nocturnal creatures among the upcoming enemies, and the evolution direction of the visual organs has long been closer to the darkness, and the bright light will cause damage to their retina.

Even if most mutated creatures don't rely entirely on vision for perception, being able to cause some interference to them is already a great gain.

After all, this is how the advantage on the battlefield is accumulated little by little.

No one can say for sure, but which idleman will be the straw that crushes the camel's back.

The light reflected by the searchlight also comes with unplanned benefits.

That is, to give courage to those who have no experience in group combat, so that they can clearly illuminate the enemy's dynamics and position in their field of vision.

As soon as the outcasts try to turn around and run towards the base, the bright light will immediately cause them to lose their sense of direction.

Zheng Xiao stared closely at the big screen in the command room and asked:

"Has the preliminary assessment report for the calculation of the battlefield situational awareness system come out?"

"Right now!"

The dispatcher immediately divides a small area on the screen and projects the data calculated by the AI.

In the picture, the number of mutated creatures detected at the beginning is shown as a histogram, climbing upwards at a rapid speed, and the scale of the ordinate is also expanding by multiples.

After a few seconds, the table finally calmed down and presented an eye-popping number:

“1.9w+!”

In the pie chart on the right, the species structure of the Mutant Legion is marked in different colors:

"Swift Seed: 33%"

"Armed species: 26%"

"Savage: 19%"

“……”

These constantly beating numbers drained the air in the command room like a storm, and the cold and cruel tickled at the nerves of every officer.

Zheng Xiao's face didn't have any superfluous expression.

"Too little!

The calculation model is too conservative, and the parameters are magnified by 3 times and adjusted immediately. ”

A layer of cold sweat broke out on the data analyst's forehead, and he questioned, "Commander, the calculation model used by AI has just been revised and has been verified by the military department, and in our past use experience, the sample error is no more than 5%......"

"Don't talk nonsense, carry out orders." Zheng Xiao interrupted him, but he still added his own reason, "Have we ever encountered a 'black tide' of this scale in the past?" ”

Data analysts can't argue with that, they can only do it.

After more than ten seconds, the data on the screen scrolled rapidly again.

This time, according to the parameter coordinates required by Zheng Xiao, the number of mutated creatures reached a terrifying level of 100,000.

"Immediately send this report to the rear command, and issue a second-level invasion warning, apply for emergency support!"

The officers looked at each other, and they all felt that Zheng Xiao's reaction was a little excessive, and even crazy.

Once the secondary alert is activated, it means that the forward base is close to losing the ability to resist.

It is very likely that the command will misjudge the battle situation, and may even directly mobilize missile units to carry out long-range saturation fire strikes.

At this time, they have not yet had a head-on conflict with the Kuroshio, and they may be under the devastating blow of their own side.

The staff officer swallowed and had to stand up.

"Commander, I think you are too pessimistic, the situation is far from deteriorating to that extent, we can wait a little longer."

Zheng Xiao didn't even explain, and immediately slapped the table hard.

"Execute the order!"

The law of the military department was extremely strict, and the commanders of the front-line units were fully authorized to deal with any officer of a lower rank without request in wartime.

The commander's orders may be wrong, but the results of disobedience are even more terrible than death in battle.

Under Zheng Xiao's strong posture, this highly controversial report was still passed to the rear.

Shortly after it was issued, the officer in charge of the communication network immediately said with an ugly face:

"Detection of large-area electromagnetic interference......

Communication with the rear was completely cut off. ”

At this moment, all the officers in the command room were dead.

Finished!

As soon as the second-level invasion warning was handed out, the command lost contact with the forward base, and the rear was likely to make a judgment based on this that the forward base had fallen.

The command has no scruples and is likely to give the order for a devastating saturation strike......

Zheng Xiao didn't pay attention to the other people's thoughts.

What he was thinking at the moment had gone beyond the height of a front-line commander, but was standing in the overall situation, thinking about how to create an advantage in this war to the greatest extent.

"How many thermobaric bombs are left at the base?" He asked.

The officer in charge of logistics and ammunition management was stunned for a moment, and then replied, "34!" Of these, 25 are in combat condition, and 9 are undergoing routine inspection and maintenance. ”

"25? It's a little little, but that's all. Zheng Xiao muttered softly, and then gave an order aloud, "In 10 minutes, all the stabilizing bombs will be launched, and the coordinates will be in a circular range with a radius of 4 kilometers from the base as the center." ”

Thermobaric bombs, also known as cloudburst bombs, are conventional weapons of mass destruction second only to nuclear weapons, and the BU52 thermobaric bombs equipped with the base are powerful enough to scorch an area within a radius of one kilometer.

The high temperature and high pressure generated by the explosion of the thermobaric bomb can spread in all directions, causing chemical changes in the nerves and blood tissues of the organism in an extreme time, and the oxygen in the central area will be quickly drained, which can hit the living force in the range to the greatest extent.

And at a distance of 4 km, 25 thermobaric bombs exploded at the same time, and the shock wave could even cause serious damage to the base.

"I'm against it, it's too close, and we're also in the range of thermobaric bombs!" An officer retorted.

"Only this once," Zheng Xiao didn't even raise his head, "there is no room for a second voice in my troops, especially in wartime. If you survive this battle, you can be court-martialed, and now ......"

"Execute the order immediately!"

"If anyone questions my orders again, the gendarmes, shoot them directly!"

"Yes!"

More than a dozen gendarmes with red trim on their cuffs immediately responded.

……

Front.

The dense mass of mutated creatures had crashed into the area of the searchlight.

The displaced people could not withstand the suffocating pressure and pulled the trigger when they were out of range of the firearm.

Generally speaking, the effective firing distance of an ordinary automatic rifle is only five or six hundred meters, and beyond this distance, the trajectory will deviate under the influence of gravity, wind, and air humidity, and the accuracy will drop significantly.

At this time, the vanguard of the Kuroshio was still 2 kilometers away from the position, and it was a problem whether the bullets could reach it.

After the first shots rang out, the other homeless people woke up from a dream and pulled the trigger indiscriminately without aiming or assigning the strike area.

Fortunately, there are so many mutant creatures and they are huge, so there will always be unlucky people who hit the gunline.

Chen Yu didn't shoot immediately, he was given a PL-59 automatic rifle, although the model is very old, but the caliber of 7.62mm still guarantees the power.

He took off the magazine and observed that the warhead of the bullet was very different from that of a regular bullet.

The warhead is carved with spiral lines, and these shallow tiny dimples are filled with a fluid substance much softer than the alloy shell, which shows a bright color in the light.

It's a Mithril substance.

Chen Yu couldn't help but sigh.

This magazine is already enough to catch up with his annual income.

Only the military department with deep pockets has the confidence to carry out large-scale installations.

Of course, there are advantages to being expensive. The Mithril Warhead has a special killing effect on mutated creatures, and ordinary soldiers armed with Mithril guns can also effectively kill mutated creatures.

Chen Yu readjusted his guns and observed the movements of the black tide.

Although the outcasts' shots were not accurate, many bullets still hit the enemy.

There are very few mutated creatures that can be killed or severely damaged.

Because of the waves of the Black Tide, there are rows of monsters holding bone giant shields and charging rapidly.

They are more than 3 meters tall, covered with bone armor, and when a bullet hits their body, it does not hurt or itch, only a string of sparks.

These monsters with incredible protection were like a circle of flowing barriers, blocking most of the firepower.

Behind them, is the species that has evolved weapons such as blades and sickles, and their protective power is not so exaggerated, but they are well protected by the giant shield monster in front of them.

Once they break into the position, these monsters with sharp weapons are only when it is time to really play.

Kuroshio's formation is not complicated, but it is very effective.

Clearly, there is a brilliant commander at the helm of this massive army of monsters.

The mutated creatures of different races are not monolithic, and even have a predatory relationship, and many populations do not even have much intelligence. It is unbelievable that the commander hidden in the shadows can suppress the wildness and racial barriers of the monsters, so that they can fight in unity and cooperate with each other.

Human beings will have different customs and dialects due to different regions and climates, and it is extremely difficult to dispatch soldiers from different regions to order and prohibit them, not to mention mutated creatures with different intelligence levels.

To be able to do this, the creatures that command the Kuroshio are so powerful that they are desperately powerful.

One kilometer.

A shadow was buried in Chen Yu's heart.

The sound of gunfire in the ears was endless, and the sparks from the muzzles of thousands of guns overlapped, even brighter than the light of a searchlight.

But the vanguard of the Kuroshio was not hindered in the slightest.

Stable, calm, high-speed!

At this rate, in a few minutes, the defensive front of the homeless people will be completely shattered by the Kuroshio.

At this time, someone had already shot out of bullets and began to snatch the guns of the others next to him.

Someone had already dropped their guns in a panic and was running in the direction of the barbed wire.

The guns of the displaced people are no longer uniformly pointed forward. Danger can come from them at any time, and they have to guard against the cold guns that come from their sides at any time.

The line of defense formed by this rabble, under the fear of which there was already rioting, was a precursor to its collapse.

If we can't get rid of those monsters with giant shields, it is impossible for these thousands of outcasts to cause any obstacles to the Kuroshio.

Didn't the commander of the base find out about this?

What exactly was he waiting for?

Just when Chen Yu was in doubt, there were suddenly whistling waves of sound in his ears.

One after another, the anti-tank missiles dragging orange flame tails suddenly moved away from the ground at an altitude of less than 10 meters, and suddenly turned 90 degrees from a position close to the Kuroshio Tide and rose from the ground, like Kong Ming lanterns flying all over the sky.

After climbing the road at a height of fifty meters above the ground, he turned again and dived directly below, and with the blessing of gravity, he rushed into the forward of the Kuroshio at a terrifying speed far exceeding the speed of sound.

Rumble!

Rumble!

……

One after another, anti-tank missiles fell from the weakly protected head of the giant shield monster, exploding incomparably brilliant fire.

The sound of explosions was undulating, and the screams of the monsters before they died were incessant, and soon a sea of fire was intertwined.

These anti-tank missiles are also frequented, with the blessing of Mithril and accelerants, they bloom like fireworks.

The air was mixed with gunsmoke, chemicals, and the burning smell of burning flesh, and a violent explosion was not far away, provoking the eardrums with impunity.

But in the ears of the homeless, it is so pleasant.

The achievements of human civilization have withstood the test in the face of mutated organisms, and the results have been very impressive.

The giant shield monsters were eliminated one after another, and the defensive mutant creatures that followed the charge were exposed, and even the array was chaotic under this round of firepower.

Courage and enthusiasm are encouraged and stimulated, and they infect each other at a great speed.

Refugee. A cheer erupted in the front, and someone shouted:

"Kill!"

Adrenaline rushes, blood gushes, and the seeds of hatred are ignited, masking fear.

All sorts of gunfire rang out one after another, like a prelude to the movement of resistance and killing.

"Kill!"

"Kill all these brutes!"

"Here's your chance for revenge!"

“……”

The sound of shouts and guns tore apart the false tenderness and tranquility of the night, and hideous and bloody followed.
