Chapter 1755: Building a Closed Loop Ecosystem

Cuckoo took the registration book and walked around the greenhouse.

Registered all the performers, signed them, and reminded them of the relevant precautions.

Because the notice of the New Year's Eve party was issued too hastily, it was a mess.

This made Zuo Ruxue and Cuckoo feel a little unsure.

As time passed, the on-site layout in the No. 52 greenhouse became more and more perfect.

They even got a lot of colored lights and arranged them in the entire venue.

The star-shaped colored lights flickered in the greenhouse, plus flowers and green plants, and the red carpet in the center, making the entire venue full of festive atmosphere.

In the rehearsal room next door, the people who were going to perform on stage were also stepping up rehearsals to ensure that this performance would go smoothly.

Outside the greenhouse.

There was also a row of roll-up banners hanging outside, with a few big words on them: Happy New Year.

Da Zhangshu Base, Outer City.

Arsenal.

At present, this arsenal has five bullet production lines, which can produce a lot of bullets every day.

Da Zhangshu forces also consume bullets.

For example, every time the transport brigade goes out, a certain amount of bullets must be consumed.

There are also guards stationed in the sentry towers to protect the mines.

Zombies can often be encountered.

In addition, target shooting in the training ground will also consume bullets.

However, the current rate of bullet consumption is not as fast as the rate of bullet production.

Therefore, of the five production lines, they only maintain the production of two production lines.

Once there is demand, they can immediately double the production of bullets.

The raw materials for producing bullets are now fully mastered. The copper, steel, and lead required for bullet shells can be found in the mines and refined.

As for gunpowder, given the current strength of the Dazhangshu base, they have also found raw materials to manufacture it.

In addition to these five bullet production lines, they also have two small-caliber artillery production lines.

There is also a hot weapons maintenance department that specializes in repairing weapons such as firearms and artillery.

"Director Zhou, how is the production of fireworks and firecrackers here?" He Chao walked into the arsenal and asked Zhou Ran, the person in charge of the arsenal.

Zhou Ran used to be a person from the state-owned machine tool factory and had followed Lao Qin.

Currently working in the camphor tree base, the supervisor is responsible for the upper and lower affairs of the arsenal.

Hearing He Chao's voice behind him, Zhou Ran turned and looked at He Chao.

"He, firecrackers and fireworks are simple. We have made them now and are preparing to go to the fourth outer city for experiments. Do you want to take a look?"

"Okay, Director Zhou is really efficient." He Chao gave a thumbs up and praised.

Zhou Ran shook his head helplessly.

It's really a luxury for the people in their arsenal to make fireworks and firecrackers.

These gunpowders are all used to make bullets and kill zombies.

However, the productivity in the base is now saturated, and it is harmless to take out a very small amount of flames to make fireworks and firecrackers.

This time, he received an order from the upper level to make a small amount of fireworks and firecrackers for this New Year's Eve party.

After debugging, it was made soon.

However, these fireworks and firecrackers are quite powerful.

"Old Song, take these fireworks and follow me." Zhou Ran said to Song Yiming.

Song Yiming was a weapons manufacturing expert in the North. Asking him to make fireworks and firecrackers was like using a cannon to kill a mosquito.

Soon, they arrived at the fourth outer city.

Pushing open the gate of the training ground.

Most of the training ground is open-air. Now the temperature is minus fifty degrees, and there is basically no training activity.

Moreover, the training ground is large and wide, with few people around. It is also a closed space, which is very suitable for experimenting with the effect of fireworks and firecrackers.

They came to the shooting range, and there was open space within a hundred meters around.

The cold wind was biting.

Song Yiming asked the workers to put two firecrackers in the center.

The firecrackers they made were much larger than the ordinary firecrackers before the end of the world, at least three or four times larger.

Each one looked like the size of a bullet.

They spread out the firecrackers, lined them up, and placed them on the snow.

It was about six or seven meters long, and the workers raised their hands to indicate that they could be lit at any time.

Zhou Ran looked at He Chao, "Director He, shall we start now?"

"Let's start. I haven't heard firecrackers for many years." He Chao said with some emotion.

He remembered that when he first came to the Dazhangshu base, the base had a rule that people were not allowed to make too much noise. Even at that time, everyone defaulted to not clapping, because they were afraid that too much noise would attract zombies.

But as the Dazhangshu base grew and grew.

The base has been surrounded by zombies countless times.

There have even been many cases of zombies piling up.

Attract zombies?

So what!

Besides, the zombies within a dozen kilometers around the Dazhangshu base have been cleared by them one after another.

Now it is the coldest time of the year, and no zombies have been seen for many days.

They have long returned to normal, speaking in normal voices and broadcasting normally, and they are not afraid of attracting zombies. After all, if zombies are attracted, the zombies can't do anything to their Dazhangshu base.

Let alone the outermost buffer city wall, it is nearly 40 meters high.

Mobile gates, ultraviolet lights, and cameras are installed on the fence to monitor the movements on the fence at all times.

In addition, there are patrol officers on duty in rotation, providing multiple layers of security.

Outside the buffer city of the camphor tree base, all trees within two kilometers were cut down, just to ensure that the vision of the guards on the wall can see far enough.

Training ground.

Zhou Ran nodded to the worker and shouted: "Light it!"

The worker took the lighter and clicked!

The flame slid out.

Zizizizi--

The fuse, which was nearly 20 centimeters long, sizzled and smoked.

The worker ran and ran to Zhou Ran and his friends.

Zhou Ran and his friends were about 10 meters away from the firecrackers.

When the worker just ran to Zhou Ran, the firecrackers behind him exploded instantly.

Bang bang bang bang!

The snow on the ground was blown away and splashed on Zhou Ran and his friends' heads.

The explosion lasted for about half a minute.

Gun smoke filled the air, a white smoke.

When the white smoke was blown away by the wind, small pits were blown out of the snow on the ground, about four or five centimeters deep.

"Uh"

He Chao swept the snow off his head and looked at Zhou Ran with some palpitations.

"Director Zhou, is this firecracker too powerful?"

The surface of this firecracker is wrapped in paper, so the damage caused by the explosion is not that strong.

If the paper is replaced with iron or plastic, the lethality will increase.

Zhou Ran coughed to cover up his embarrassment.

"Well, let's reduce the gunpowder in it by half. The power is a bit strong."

He Chao frowned, "No, not enough, at least reduce it by three quarters. With such a strong power, if the distance is closer, it will hurt people."

"Okay, I'll change it later." Zhou Ran looked at the worker and asked him to arrange the fireworks.

Two workers carried a box of fireworks over.

These fireworks and firecrackers are all modified based on the gunpowder of the bullet production line, so they are more powerful.

"Director He, cough cough, the power of that firework is probably stronger than that of the bullet. Why don't we take two steps back." Zhou Ran said to He Chao.

He Chao wanted to curse in his heart.

Damn it!

Are they making fireworks or bombs?

The fuse of the fireworks is longer, reaching one meter long.

This also gives the person who ignited it enough time to escape.

The worker repeated the previous operation, checked the fireworks, and lit them.

He ran away.

This time he ran faster.

Just kidding.

This is more dangerous than firecrackers. Fireworks are centralized. If the gunpowder inside is connected in series, the explosion will be extremely powerful.

Firecrackers are at least single and lined up in a row.

He ran to the back of their parked car, about 30 meters away from the fireworks.

Boom!

I saw a correct version in the 16-9 book and forum!

Whoosh whoosh whoosh!

Several fireworks streaked across the sky and exploded.

Bang!

Bang bang bang!

The sky burst into brilliant light.

Then, several more fireworks flew into the sky, bang bang bang!

So beautiful!

He Chao was a little amazed at the fireworks flying hundreds of meters high. They were indeed made by the arsenal.

It was awesome.

The fireworks he had seen before the end of the world were only a dozen meters high, and the highest was dozens of meters high.

But the fireworks made by Zhou Ran and his team were at least a hundred meters high.

Bang Bang Bang!

The fireworks were still blooming.

At this moment.

In the camphor tree base, people in the inner and outer cities or the buffer city heard the sound and ran out to watch.

Because it was daytime, people who were farther away could not see clearly.

But people who were closer to the fourth outer city could see it very clearly.

They looked at the gorgeous fireworks with surprise in their eyes.

It was the end of the world, and there were still things like fireworks.

The camphor tree base was really magnificent.

One minute later.

Training ground.

He Chao looked at the fragments of the fireworks paper box after it exploded, and there was a large pit with a radius of several meters, and fell into deep thought.

"Hey, can we also reduce the power a little bit? Keep the current height of the fireworks, but can we reduce the power?"

Zhou Ran looked at the pit created by the explosion and said quickly: "No problem, for sure, this is not a test."

"Okay, then reduce the power. This explosion is too powerful, it's not good."

He Chao reminded:

"The city lord will come to watch at that time. Your power is too powerful and the hidden danger is too high. What if the city lord is injured."

He Chao didn't finish, but Zhou Ran understood the key.

He nodded like a chicken pecking at rice, "Don't worry, Director He, I will go back and adjust it."

Everyone put the remaining paper box fragments of fireworks into the car and drove away from the training ground.

The inner city of the big camphor tree base.

The two tall mountains surrounded a reservoir.

And on the hillside, there are several caves.

These caves were dug and built step by step over the years.

Most of them were built to resist natural disasters.

At present, some of these caves are used to store valuable materials, and some are used as indoor plantations, indoor breeding farms, and fisheries.

Li Yu stood at the entrance of the cave and looked towards the direction of the Fourth Outer City.

He just heard the explosion and ran out of the cave in a hurry.

The Fourth Outer City was not very clear from here, but with his good eyesight, he could see clearly that it was fireworks.

"This firework is so powerful!" Li Yu sighed.

Turned and entered the cave.

In the cave, Lai Dongsheng, his father, and Zhou Weiguo were all here.

There are pools made of cement everywhere in the cave. Oxygen pipes are inserted into the water and the water surface bubbles.

This cave covers an area of ​​approximately 2 acres, which is quite large among caves.

They keep most of the fish, shrimps and crabs here.

In rivers and lakes in the apocalypse, many aquatic creatures are eaten by zombies.

Coupled with so many natural disasters, many fish and shrimps in the south have been frozen to death, or died of drought due to lack of water.

The fish, shrimps and crabs cultured in the Da Zhangshu Base are still alive and doing well.

Because every time before a natural disaster comes, they will concentrate on catching these fish, shrimps and crabs in the Shantang Reservoir and put them in the indoor fisheries at the foot of the mountain and the cave.

Not just fish, shrimp and crab.

The same goes for breeding farms.

Over the years, after they have determined that the wild animals they captured outside are not infected with the zombie virus, they will be kept in isolation.

Such as elk, wolf, golden monkey, pangolin, South China tiger, hedgehog, fox, panda, etc.

Among them, the panda was the one I encountered on the way back when I went to the Western Conference, so I simply captured it.

Originally, they planned to kill the meat-eating ones directly, but considering that giant pandas were too scarce, they were not short of food at that time.

Even if they were killed, they wouldn't be able to eat much meat, so they raised the few red pandas.

Anyway, there are a lot of bamboos in the base, which can feed them.

Cases like this have happened many times.

But most of the wild animals caught mainly have one characteristic, that is, they are more cute and cute.

Time has passed, and today, seven years later, the number of animals in the Da Zhangshu Base has exceeded 150 species. They have tried their best.

These wild animals are not plentiful and it is not difficult to feed them.

As for cattle, sheep, and pigs, they are the most numerous, and they are raised solely for meat.

Da Zhangshu has developed to this day. As a super large force, it has to consider the future from a human perspective.

For the sake of biodiversity and considering that the living environment outside is too difficult, they continue to do this.

In the cave, Li Yu's father Li Hongyuan was fishing with a fishing rod. When he saw Li Yu coming back, he asked worriedly:

"Xiaoyu, what was the big explosion outside just now?"

Li Yu closed the cave door and said with a smile:

"I guess they are experimenting with fireworks. My second uncle said that since we are celebrating the New Year, we must have fireworks. Without them, there would be no New Year flavor."

"I thought since we don't lack this little gunpowder, we might as well get some firecrackers to celebrate."

Li Hongyuan breathed a sigh of relief when he heard the sound of fireworks.

He thought it was some pipe explosion in the industrial area.

After all, in this kind of weather, no enemies should be coming, and there are currently no enemies in the Da Zhangshu Base. Only the northwest base is a threat.

"Fireworks and firecrackers."

"I haven't seen it in several years. Before the end of the world, we were not allowed to release it. But now, it's strange to see it released in the end of the world."

Li Hongyuan looked at Lai Dongsheng and said with a smile:

"At that time, the control was very strict, and bacon was also regulated. Lao Lai, do you still remember that you were smoking bacon in your yard, and you were fined 200 or something?"

Lai Dongsheng smiled bitterly and shook his head and said:

"Yes, I was fined 200 yuan, and I also wrote a guarantee letter."

"It was very uncomfortable for me at the time. It was so difficult for me to earn two hundred yuan. You said you were smoking bacon, and I was fined."

Li Hongyuan pointed at Lai Dongsheng and smiled: "Hahaha, then"

Li Yu watched the fish float and said, "Dad, the fish is hooked!"

"Hey!"

Father Li turned his head and saw the fish float sinking, "It's true."

He slowly pulled the rope and lifted it up.

A golden carp surfaced.

(asking for monthly ticket)
