End of the World: My Items Can Be Upgraded Infinitely

The life radar of the lv19 flying wing tank is much stronger than Lin Feng's personal telepathy.

The detection range of five kilometers can detect a semicircle with a radius of five hundred meters under the surface, and naturally can detect the movements of the Zerg underground in advance.

At this moment, there are already many red beetle swarms that have dug out nearly a hundred meters deep wormholes from the foot of the service area into the urban area of ​​Wucheng.

If even they are like this, then the front line of defense is estimated to have been dug through by the Zerg and infiltrated.

After all, that is where the main force is fighting.

At least 90% of the exchanges of fire occurred outside the solid defense line that stretches for twenty kilometers.

Shen Jie believed in Lin Feng's words.

Last time, he was also alert in advance, allowing himself and other team members who went to harvest to evacuate the hinterland in time, so that they were lucky to escape the sneak attack of the second-level Zerg, the tiger spine worm.

Thinking of the scene of being chased by three golden giant insects, the speed was close to 100 kilometers per hour, which made Shen Jie, who stepped on the accelerator hard, still remember it vividly.

Now a greater danger is about to come.

This is undoubtedly a heavy challenge for the outpost base with insufficient manpower.

Once the black-spine insects break through the city wall, the 201st company, which has no defenses, will definitely suffer heavy casualties.

The experienced Li Ran also realized the danger of being surrounded by the insect swarm.

Don’t think it’s so easy to deal with the black-spine insect swarm attacking from the east now, because most of the manpower is arranged in the direction facing the Zerg territory.

Once it is attacked from the front, back, left, and right, and the manpower is dispersed, it is difficult to have such a dense firepower output as now.

Lin Feng saw the heavy worry on the two's faces. As the backbone of the team, he comforted them:

"Don't worry, there is enough fuel for the generator at present, and it will work for several days. At night, the searchlight will be turned on, and everything within hundreds of meters will be visible..."

"Let the team members cooperate with each other. With my support, even if there are tens of thousands of black-backed insects, we can bite them hard."

"As long as we survive this battle, the queen mother will either put the main force on the front line of defense or send more powerful second-order tiger-backed insects, but no matter which one, we can achieve our goal!"

"Notify the team members to be ready."

"For the team members who are about to awaken in this battle, let them take turns to rest and complete the awakening first."

As he said, Lin Feng shook the bright black gun in his hand.

Seeing the powerful weapons in the hands of the other party, Shen Jie and the others recalled the large-scale coverage bombing they had seen in the suburbs, and gradually calmed down.

They finally remembered that Lin Feng's first display of superpowers was the famous super-powered bullets!

And this powerful superpower has the ability to influence the outcome of a small war!

Looking at the entire 13th Division, among nearly a thousand awakened people, there are only three super bullet awakened people, and each of them is a treasure among treasures.

Their treatment is one level higher than that of ordinary physical enhancement awakened people, and the weapons they hold are also specially equipped for them by the research institute, which can release the super power injected into the shells to the maximum extent.

Let the ordinary grenade increase its power by more than ten times.

Therefore, the outpost fortress is guarded by Lin Feng. Except for the lack of reinforcement, in other aspects, it is actually much stronger than the main fortress on the front line.

At this moment, in the 100 main fortresses, the commanders on the front line also received news from the technical department, detecting a lot of vibration noise underground, and the Zerg have dug holes underground to cross the defense line.

It is very likely that tonight, under the cover of night, they will carry out front and back pincer operations.

If the reinforced company of 150 soldiers is divided into two, the firepower will be directly reduced by half.

Moreover, these new recruits who have just become enhanced people have not experienced night battles. Not to mention the lack of experience, many new recruits are nervous and even have difficulty aiming and shooting.

Although the speed of the black-backed insects is not as fast as that of cars, it is far faster than that of humans, comparable to beasts such as lions and tigers. It is actually very difficult to hit them in the middle of the night when the vision is limited when they attack at full speed.

This is also the reason why the veterans are worried.

There is no entrance door on the front of the defense line, but on the side facing Wucheng, under the corridor between the main forts, there are two narrow doors with a width of only one and a half meters.

When it was designed, it was originally intended to be narrower. After all, as long as the Zerg invasion can be prevented, the personnel hiding in the defense fortress will be absolutely safe.

But considering that equipment, materials and instruments need to be moved into the main fort, and the speed of personnel transfer during the later evacuation...

So the entrance and exit door originally planned to be one meter wide was expanded to one and a half meters.

With this width, the black-backed insects will definitely not be able to get in.

Even if they look like long-legged spiders, they are more than two meters wide after retracting their limbs.

But what the officers are worried about is not the black-backed insects, but when they launch an attack, the defenders will be distracted, allowing a large number of red beetles to break in directly from the door.

These low-level bugs are just big enough to fit into the gate, causing chaos inside the defense line.

Although the recruits, as enhanced people, can quickly clear the red beetles with rifles, it is easy for large-scale riots to occur in such a state of high nervous tension.

This gives the black-spine bug army an opportunity to take advantage of.

The black-spine bug's huge jaws cannot attack the solid concrete wall, but it can break through the iron door at the entrance and exit, and bite the door railing to expand the entrance.

In this way, it won't take long for a large number of black-spine bugs to rush into the fortress and break through the defense line.

Only by eliminating the black-spine bugs outside the city wall can the safety of the defense line be guaranteed.

As orders were issued one after another, the recruits who had just experienced some small-scale battles and had not yet come out of the joy of victory were about to face the night defense, which was several times more difficult.

Fighting during the day was just a preliminary test of the Zerg.

Find out the firepower level of the defense line so as to make arrangements in advance for the general attack at night.

As sporadic gunshots came from the defense line, the sun gradually set and night fell on the earth.

The vibration of the generator sounded, and countless searchlights emitted straight apertures from the shooting window layer of the ten-meter-high city wall.

The shooting window was only half a meter high, so there was no need to worry about the attack of the blue-winged insects, and it was enough for the soldiers to turn their guns.

Because they had to defend the two directions inside and outside, the personnel layout was divided into two, and the firepower density was greatly reduced.

At this time, heavy weapons such as mortars and rocket launchers in the main fort became the last means to fight the enemy.

Because they were limited in number, they could only be used at the most critical time to alleviate the Zerg offensive.

And the three super bullet awakeners were secretly placed in the main fort of the defense line to deal with the night attack.

When it was midnight, the tense atmosphere lingered in the defense line for a long time.

Until the moon was covered by a black cloud.

When the brightness of the entire city dimmed a little bit...

Suddenly, a large number of red beetles emerged from the green belt beside the road not far away and the trees and grass everywhere, followed by a huge army of black-spine insects with limbs shaking.

The Zerg's midnight attack finally started!

At the same time, on the front battlefield on the east side, countless black-spine insects rushed out together, fearless of life and death, and rushed towards the solid concrete defense line.

The entire battlefield was so wide that more than half of the hundred main forts were engaged in fighting.

Thousands of heavy machine guns and hundreds of machine guns fired fire snakes and explosions, which had covered the sound of nearly ten thousand rifles.

Bullets and shells hit the black-spine insects.

The explosion flames directly illuminated the night, with sparks scattering everywhere...

But these attacks could not stop their pace.

Because of the weakened firepower and the decreased chance of aiming and hitting at night, the attack strength of the defense line was far less than that during the day.

Already, nearly 30% of the black-spine insect swarms had rushed into the hundred meters outside the defense line.

They rushed directly to the bottom of the defense line, like stacking blocks, trying to climb to the shooting window above and attack the enemies inside.

In the back city, the red beetle swarm directly dug a wormhole not far below the defense line. Those black-spine insects cooperated with them, and gradually twisted and deformed the seven or eight centimeters thick iron door by swinging their jaw hammers.

Many soldiers obeyed the order, poked their guns out of the lower secret compartments, and fired crazily.

Or fired grenades from the top shooting window to attack the Zerg army that rushed to the front.

At the same time, three super bullet awakeners in the 13th Division were cooperating with the artillery to carry out firepower coverage strikes on several places where Zerg swarms gathered in large numbers.

Weaken the support of the Zerg as much as possible.

Just as the battle was in full swing and extremely fierce, the senior staff who came from the division headquarters to guide was being held in the basement of the main fort in the second line of defense.

At this moment, the members of the awakening camp were basically sent to the first line of defense to cooperate with the company to fight.

And in the second line of defense five kilometers away, in addition to the garrison soldiers, there are also middle-level commanders on the front line.

Among them is the highest commander of the awakening camp.

The newly promoted second-level awakener, Cheng Zhan, Colonel Cheng.

Under the dim light of the dungeon, he was interrogating the senior staff, where is the fuel-air bomb placed by the senior leaders in the first line of defense.
