Apocalypse Rebirth: 3000 million won at the beginning

Chapter 2184 Sound Wave Resonance Corpse

As soon as Su Yan finished speaking, Liu Jianwen offered his thoughts:
"Then just find a knife processing plant and continue producing guillotine blades. We have a lot of tungsten ore stockpiled anyway."

"With the production capacity of our base, surely the production speed can't keep up with the rate at which the blades break down."

"Uh..." Su Yan glanced at Liu Jianwen somewhat awkwardly:

"Actually, there is an even better way."

Second Uncle Li Hongda looked at him and asked, "Tell me about it."

Su Yan mustered his courage and spoke:

"Actually, all you need to do is replace the original guillotine blades. The guillotine blades used before were made of cemented carbide and manganese steel. The blades made of these two materials have a very good balance of hardness and toughness."

Firstly, this type of blade is effective at killing ordinary zombies.

The second type of blade, compared to tungsten carbide blades, is more resilient, so even if it hits a Vajra zombie at high speed, it will not break like the current tungsten carbide blades.

Even after repeated collisions with the King Kong zombies, the metal will wear down and become dull, but it can be repaired and polished for reuse.

"Therefore, I suggest switching back to the original guillotine blades."

Everyone was somewhat surprised when they heard his words.

A guillotine blade made of emotion is not as good as the original blade.

However, Li Hongda did not believe his one-sided story, so he asked Li Gang to call Zhao Sunli, the director of the knife factory.

Ten minutes later.

Zhao Sunli hurriedly arrived at the command hall.

Upon entering, he saw a room full of big shots, and Su Yan standing in the corner.

He was accompanied by He Bing, Vice Minister of Science and Technology.

As soon as the two of them came in, the second uncle explained the problem of tungsten steel alloy guillotines being prone to breakage and told them about the suggestions Su Yan had made.

After listening, He Bing nodded and said:

"From a materials perspective, that's indeed the case. We previously used a combination of cemented carbide and manganese steel, which balanced hardness and toughness, but..."
Using the original guillotine, which collided violently with the King Kong zombie during rapid operation, it was not easy to break, but it was prone to dulling.

Once the zombies become dulled, problems will arise when facing hordes of zombies, especially ordinary zombies.

Tungsten steel blades have high hardness, are not easily deformed during cutting, and have low dullness, while manganese steel blades have relatively low hardness, are easily deformed during cutting, and are relatively less sharp.

Therefore, my idea is: the spine of the knife will still be made of carbide and manganese steel, but the blade edge will be inlaid with segments of tungsten steel. Even if one segment is damaged, that small piece of the blade can be replaced, without having to replace the entire knife.

"Moreover, tungsten steel blades are much sharper than manganese steel blades, and their power is definitely greater when cutting through ordinary zombies."

After he finished speaking, considering that everyone was not a professional, he borrowed some draft paper and a pen and drew a diagram of the new blade.

Looking at the draft, Zhao Sunli nodded vigorously and said, "I think Minister He is right. His method is feasible."

Liu Jianwu continued to ask:
How many of these blades can a knife factory produce per day?

After pondering for a moment, Zhao Sunli replied:
"This kind of blade can be brazed from the existing guillotine."

"If all the production capacity of the tool factory is utilized, it is estimated that 4000 guillotine blades can be modified per day."

Everyone breathed a sigh of relief after hearing Zhao Sunli mention the knife factory's production capacity.

One day's production capacity is enough to replace the first layer of guillotine blades.

The threat posed by the guillotine blades from the Vajra zombies is not a problem at all.

After listening to the discussion, Li Yu, who was sitting in the center, spoke up:
"That's settled then."
"Zhao Sunli, you need to modify the blades as soon as possible and send the first batch of modified blades to Edge City immediately."

Zhao Sunli straightened his back and nodded, saying, "Yes, sir, I guarantee I will complete the mission."

Li Yu then looked at Su Yan:
"Su Yan, once you get the modified guillotine blades, immediately conduct small-scale experiments. If the results show that the blades are indeed better than the current ones, then replace them all."

"As for the existing tungsten carbide blades, they can be recycled and reused to make tungsten carbide alloy bullets or segmented blades."

"also."

Li Yu looked at Yi Jing and said, "Old Yi, give the order to the brothers to accurately shoot the King Kong zombies. These things are too much of a threat, so try to kill them as much as possible."

It also provides an opportunity for the brothers to hone their marksmanship in real combat.

The commander-in-chief had spoken, and no one dared to object; they all echoed his words.

Two hours later, the first batch of manganese steel blades brazed with tungsten steel was delivered to the outer wall of the city.

At this moment, outside the edge of the city, the gathered zombies had completely surrounded the city.

Even outside the southern city wall, piles of zombies over ten meters high had formed.

boom!
A combatant, holding an automatic rifle, aimed at the head of a King Kong zombie in the horde of zombies.

A bullet struck the King Kong zombie precisely in the head, and even pierced through several other zombies behind it.

These tungsten steel bullets have extremely high penetrating power and are currently the only bullets capable of killing King Kong zombies.

The King Kong zombie's skin is silvery-white, and when light shines on it, it reflects light, making it relatively easy for combat personnel to find them among hordes of zombies.

Outside the walls, besides the King Kong zombies, there are many other types of zombies.

There are towering, five-meter-tall giant zombies, and another type of zombie that resembles a cat but is much larger.

These zombies climb quite fast, but they don't have the same skin as the King Kong zombies, which is strong enough to withstand tungsten steel guillotines. Once they reach the first layer of guillotines, they are cut in half.

sizzle-

The combatant heard Li Gang's voice through his earpiece:

"The Southern Third Squad has suspended its killing of the King Kong zombies to conduct a guillotine replacement test."

He holstered his automatic rifle and looked down at the guillotine beneath the wall.

I didn't even notice, but they've already replaced the first layer of switchboards.

After the third squad ceased firing, the Vajra zombies at the base of the wall immediately rushed towards the piled-up zombie horde and quickly reached the first layer of guillotines, which was over twenty meters high.

They had been precisely shooting at the King Kong zombies, so much so that the King Kong zombies didn't even have a chance to climb over to the guillotine.

Under the watchful eyes of numerous combatants, a dozen or so Vajra zombies climbed to the first layer of the guillotine.

The first Vajra zombie was struck by the guillotine, producing a duller sound than the previous impacts.

thump~
The King Kong zombie fell into the horde of zombies.

“This guillotine sounds much sturdier,” one of the combatants remarked.

Bang bang bang~
More than a dozen Vajra zombies were knocked down one after another.

The King Kong zombie was very heavy, and when it crashed down, it crushed a whole bunch of zombies.

Just at this time.

Buzz—Beep—

An invisible sound wave spread out from somewhere, and this sound wave was completely inaudible.

This invisible sound wave is like infrasound mixed with the high-frequency reverberation of shattering glass.

"what!"

My ears~

The combat personnel in this area covered their ears, squatted on the ground, and their faces were full of pain.

One of the combatants fell to the side and tumbled over the wall.

Seeing this, a nearby combatant quickly reached out and pulled him back.

But blood immediately started flowing from the ear that wasn't covered.

This time, the sound waves affected dozens of combat personnel, and those who were a little further away felt palpitations and nausea.

"Quickly, put on your tactical headsets!" the squad leader shouted into the communicator.

Then run to the watchtower as fast as you can and find the noise-canceling tactical headset in the box inside.

Put it on immediately.

My body, which had been teetering on the brink of collapse, suddenly felt much better.

Crack! He had just looked up when the window glass of the watchtower shattered, falling to the ground with a clatter.

He immediately contacted the company commander using his headset:
"Squad leader, our third squad has encountered a sonic attack from zombies. It's similar to the previous screaming zombies, but stronger, and we still can't locate the zombies."

The message was passed up the chain of command.

The message quickly reached the command center.

At the Second Outer City Research Institute, Bai Jie, Ma Di, and others were still studying the three new types of zombies they had just captured when they immediately received an order from Liu Jianwen to go to the South District 3 of the Outer City to check the situation.

Simultaneously.

Old Zhou from the military industry department and Qin Feng also rushed over here.

On the wall of the South Third District.

Li Gang, wearing noise-canceling headphones, looked extremely grim.

There were simply too many zombies, and dozens of different types of zombies, so they couldn't find the zombie that was emitting those sound waves at all.

"Since we can't find it, then let's bomb it indiscriminately!"

"Yes." Second Squadron Leader Zhao Chen's eyes were filled with anger.

The sudden sonic attack just now injured dozens of his men.

He was rushed to the hospital, but the severity of his injuries is still unknown.

"On my command, artillery teams and machine gun teams in Sector 1-4, aim at the zombies below and fire indiscriminately!"

"receive."

"receive"

"receive."

One minute later.

All firepower from South Zones 1, 2, 3, and 4 was unleashed towards the horde of zombies below.

Even a close-in weapon system (CIWS) joined the battle.

The close-in weapon system is equipped with an 11-barreled 30mm rotary cannon, making its firepower extremely formidable.

It's like plowing a field, sweeping across the ground layer by layer within a two-kilometer radius.

Fire shot into the sky.

The moment the firing began, shells and bullets poured out, raining down on the ground as if they were free.

The tracer bullets stretched out in a continuous line, making it seem as if we had entered daytime.

The zombies within a two-kilometer radius suffered a devastating blow.

Boom~
A shell landed next to a giant zombie, instantly turning it into watermelon juice.

da da da da~
Heavy machine gun bullets swept across.

At this point, the bullets are no longer intended to hit the target precisely, but simply to provide firepower coverage.

A zombie's chest was riddled with bullet holes.

Some zombies even had their heads blown off.

The most powerful of these is the close-in weapon system (CIWS), which fires nearly 10,000 30mm bullets per minute with tremendous impact.

A bullet fired at a zombie felt like a needle puncturing a water-filled balloon.

There were many zombies below, and they didn't even recognize all the different types of zombies.

However, under heavy fire, they were still killed.

five minutes.

Under the bombardment of 100,000 bullets and hundreds of artillery shells.

The area within a two-kilometer radius has been reduced to scorched earth.

Not a single zombie survived.

Even the towering giant zombies, the incredibly tough-skinned Vajra zombies, and the extremely agile mutated zombies were all killed in this saturation bombardment.

The soil on the ground has been reduced to scorched earth.

Thick smoke filled the air, along with the stench of rotting zombie corpses.

Some of the zombies were also burned by the explosion.

The zombies and soil within a two-kilometer radius were all mixed together.

After the bombing ended.

Li Gang took off his headset, and the sound waves disappeared.

He breathed a sigh of relief; he had finally taken down the zombie that emitted sound waves.

They had encountered screaming zombies before, whose sound waves could cause dizziness.

But this time, they couldn't find the sonic zombies they were facing!

The previous screaming zombies had very clear physical characteristics: red eyes, exposed bone spurs on their chests, and heads twice the size of ordinary zombies.

Just as Li Gang finished dealing with this matter, the voice of Wang Xin, the captain of the West District Armed Forces Brigade, came from the West Second District:
"Captain Li Gang, we've also encountered sonic zombies. The windows have shattered, but we all wore headsets beforehand, so no one has been injured yet."

"Damn it!" Li Gang slammed his fist heavily on the wall, his face full of helplessness.

His hands hurt, but his heart ached even more.

They used up so many shells and bullets in five minutes, even though they wiped out all the zombies within a two-kilometer radius.

But this is only temporary.

Sure enough, in just one minute, zombies from afar surged up again, taking the places of the zombies that had been killed earlier.

Blessings are unparalleled, and misfortunes do not come singly.

Wang Xin, the head of the West District, shouted again:

"Captain Li Gang, there's a problem with our guillotine. It seems the sound waves emitted by these sonic zombies are affecting the moving guillotine. When the Vajra zombie hit our guillotine, it shook violently and the blade broke off in the middle."

"The guillotines that collided with the King Kong zombies were mostly broken, with about a dozen blades broken off."

"We are now focusing our fire on the King Kong zombies."

"What?!" Li Gang's expression changed drastically.

The series of bad news caught Li Gang off guard.

But he quickly realized, "Yes, you did a good job. Never let the King Kong zombie climb onto the guillotine."

"Have the repairman replace the fallen switch as soon as possible."

"I'll send someone over right away."

He knew he could no longer continue using indiscriminate saturation bombing.

The appearance of the second sonic zombie told him that there were definitely more than just one or two sonic zombies.

Therefore, indiscriminate saturation bombing is not very meaningful.

The shells are being used up too quickly, so we can't keep going for too long.

The most urgent task is to get the people from the Zombie Research Department and the Military Industry Department to come and see if they can come up with a solution to quickly pinpoint the location of the sonic zombies so that they can strike them accurately.

At the same time, the frequency of the sonic vibrations may have affected the rapidly moving switch.

Otherwise, how could the switch break and fall down so easily?

Even if tungsten carbide alloy switches are used now, it's still the same; the switch failure rate shouldn't be so high.

He quickly picked up the communicator and called headquarters for command.

"Something's happened again at the Edge City walls; a new type of sonic zombie has appeared."

In just one hour it will be 2026. Wishing all my brothers and sisters a happy new year!
May your family be happy, your health be good, your wealth be abundant, and everything go smoothly. May your youth last forever, and may you still smile in the spring breeze next year!
Love you all.

I need a monthly vote, it'll expire if I don't vote soon, haha.
