At seven o'clock in the evening.

The night was deep.

Next to the towering steel fortress, a heavy truck stopped steadily.

Compared with the driver who jumped out of the car, the volume of the car can be described by the word Wei'an. However, if it is put together with the steel platform and crawler beside it, the figure of Weian will seem small.

Looking from a distance, it is like a bug crawling by the shoe.

The driver who got out of the car operated the automatic loading and unloading platform with a flat plate to unload cube metal blocks from the truck.

These metal blocks are made of recycled garbage. The specifications are cubes one meter long, one meter wide and one meter high, with a density of 6 ~ 7gcm ³ Between.

There are doors, engine covers and all kinds of metal parts, all of which are firmly pressed together. It is difficult to distinguish what they looked like before.

It has to be said that the residents of those shelters are really capable. They are not only physically strong, but also have high enthusiasm for work. They almost scrape off everything that can be recycled.

The only slot point is that things that can't be recycled seem to have been stuffed in by them

But it's harmless.

These metal blocks will later be sent to a special processing workshop, run from module to module, go through a series of automatic production processes, and finally become what they need.

The unusable waste will be automatically removed from the production line in the production process.

Wearing thick protective clothing and hard hats, the engineer unfolded the flexible screen of the tablet computer and walked towards Li De standing next to the temporary warehouse.

"Today's collection volume is 112 tons of scrap steel. I will send them to the production line later, and I can start the track replacement tomorrow."

Li De: "how much steel do we need? I mean, that kind of garbage."

Engineer: "at least 3000 tons... Maybe 5000 tons."

Li De frowned.

"Why is the error so large?"

The engineer said helplessly.

"No way, the steel quality of those civil vehicles is too poor. It is estimated that it is to save cost and weight. It is filled with a large number of carbon based copolymers that cannot be recycled. Coupled with the oxidized part, it is optimistic that 400 kg can be recovered from a ton of scrap."

"In addition, I have to say that what we need is not only steel, but also rare metals... I don't expect to get titanium or uranium in this damn place, but tungsten is the bottom line. Otherwise, we can push 500 kilometers west and have to anchor again."

Track and wheel hub are the hardest hit areas of wear and tear.

Mechanical structures such as bearings and transmission wheels, not to mention, must be replaced regularly, even if they are not as serious as the loss of track.

In fact, according to the truth, the recycling value of abandoned vehicles in the underground garage without soaking water is relatively high, and the recycling rate can almost reach 40% or even 50%.

If it is those abandoned cars exposed to the wilderness or unmanned roads, the recovery rate may be 30%.

After all, rainwater is weakly acidic under natural conditions. Even if the acidity of carbonic acid is weak, the "pickling" for two consecutive centuries will be lost even if the materials and technology are advanced.

Moreover, pickling is more deadly than oxidation. Oxidation is at least rust, and the car frame may collapse, but the metal elements are still there and won't run away. If it is acid pickling, ionized cations will be brought into the soil by rainwater, which can really not be found.

Li De frowned more tightly and carefully summed up what the engineer said to him.

500 kilometers to anchor again

According to the route they planned on the map, 500 kilometers may not be out of the river valley provinces.

If you anchor in the wilderness, you're really finished.

"I understand the situation. I will ask the people of the marine warfare section to send a search team to focus on rare metal materials in this area."

The engineer shook his head and said.

"It's hard to find it in this area. I propose to find it near the Fifth Ring Road in Qingquan city. One of the most basic common sense is that the more intensive civilized activities are, the higher the macro utilization rate of rare metals is. In particular, those maglev vehicles, whether the magnetic generation devices on the vehicles, the high buildings along the way and the maglev subgrade buried under the highway, contain what we need... This Some can't be found in the suburbs without a three-dimensional highway network. "

"In addition, the search for controllable fusion fuel rods must be carried out quickly. Only 8% of the fusion fuel is left in the fuel rod we are currently using. Even if our track doesn't break down, I'm afraid we have to find a place to stop to solve this problem."

Li De: "how long will the remaining energy be enough?"

Engineer: "enough for us to use for a long time, but you know, we can't stay here all the time."

If only that production consumption, this 8% energy is enough for them to use next year.

But as his engineers said, they can't stay here all the time.

The most energy consuming part of this land fortress is not its production workshops, but its four engines.

Pushing tens of thousands of tons of fortresses forward smoothly on land, if converted into diesel engines, it is estimated that a few tons of oil will be needed for a kilometer less, which is equivalent to 1 ~ 2 Armored Divisions marching in cross-country terrain.

Li De: "the contact point of shelter 404 has just been built. Their people are helping us find a guide. We should be able to start within two days as soon as possible. The problem should not be big."

The engineer sighed.

"I hope so. In fact, it's not so urgent to recycle nuclear fuel rods than to collect them. As long as they can be found before departure. Speaking of this, I have to praise those blue coats. Their work efficiency is beyond my expectation. What benefits have you promised them? I think their work is like taking drugs."

Speaking of the second half of the sentence, the engineer looked at his boss curiously with an incredible expression on his face.

Li De's face was also complex, and he didn't seem to know how to answer the question.

To be honest, when he saw the results of today's resource collection, he was also surprised.

According to their past experience, it's good to hire local survivors to help pick up garbage and collect 300 kg of garbage every day. After all, cutting, handling and compaction all take time, while those aborigines are stupid and procrastinate in their work, which makes people's blood pressure soar.

However, these blue coats took only one afternoon, and the per capita collection reached more than 500 kg! Reached 200% of their expectations!

If they were given a whole day, wouldn't the per capita scavenging capacity be more than one ton?

The enthusiasm for this work is almost gone!

Although it has nothing to do with himself, Li De still couldn't help wondering how much their managers paid them in order to make them motivated.

"Where are they?"

"I've come back. I'm cooking in the camp now."

Reed nodded.

Just come back safely.

At this time, a staff member of the logistics section suddenly came from the side.

"Section chief, I have your phone."

"Call me."

He took out the earphone the size of a toothpick box from his pocket and hung it next to his ear. Li De stretched out his index finger and gently clicked on the white earphone.

The dark green light beam is projected forward, and soon a three-dimensional holographic image is woven in front, showing each other's facial features and bust.

"Your holographic communication system is good. How much is it?"

Looking at the curious Chu Guang, Li De coughed gently.

"... we haven't considered selling this for the time being."

"All right."

Chu Guang in the holographic image nodded, as if to show understanding. Li De hoped that he really understood.

Squeeze a smile from his face, Li De continued.

"What's up?"

Chu Guang didn't answer this question directly, but looked at him, smiled and said in a relaxed tone.

"Nothing special. I just want to ask, how do you feel about the work efficiency of our workers?"

"Very... Very good." Li De wanted to say very good, but suddenly thought that he was facing an old fox who was good at disguise, and immediately changed his mouth temporarily.

Unfortunately, however, the other party seemed to catch the change of expression on his face, and a faint smile appeared at the corners of his mouth.

Li De suddenly felt remorseful.

Or you shouldn't have taken this holographic image communication equipment.

The original intention of this thing is to make communication more convenient.

But now it seems that only one person is convenient.

"I'm glad to get your high evaluation!"

"Well, actually, it's not as high as you think, but it's also good. I have to admit that your workers are very dedicated, which is very valuable."

"Then let's talk about the cost!"

Hearing this, Li De's expression suddenly changed. Although it is far from turning over, it is still somewhat ugly.

"My friend, haven't we talked about salary? Temporary price increases are not a sign of keeping promises."

"Please don't be nervous, my friend," Chu Guang continued after relaxing with a relaxed smile. "What I want to say is not about salary, but about... Um, value-added services."

"Value added service?" Li De was stunned, and his tense expression subconsciously relaxed for a few minutes.

It was the first time he had heard such a strange word.

Chu Guang continued with a smile, "yes, when you want to improve the efficiency of the workers, you have to put money in their pockets and bribe them to work harder rather than pay them dead wages... Or to put it another way, you have to give them a commission to make them feel the joy of growth from the process of production. Do you want to know what I do?"

Li De wanted to say he didn't want to know, but he always felt that no matter what he said, this guy would find a way to continue the topic, so he didn't speak at all.

Sure enough, the manager in the blue coat didn't let him down. The guy didn't even give him time to answer. He continued talking to himself without pause for a second.

"In addition to the hourly salary in the regulations, I will give them a sum of money for every kilogram of scrap they collect, so they will work hard. The figures you see from the production list now are not because of their courage and strength and what you said, but because I threw money."

Li De doesn't want to listen anymore.

In fact, there is only one meaning to go around.

He said with a straight face.

"How much do you want?"

Chu Guang smiled and said.

"Not much. In terms of our close relationship, how about per ton... Um, 5cr? For you, it's just a few more barrels of instant noodles."

Although he won't use the money to buy instant noodles.

After hearing Chu Guang's request, Li De didn't express his position immediately, but silently calculated an account in his heart.

If the daily production capacity is 200 tons, it means that they have to spend an additional budget of 1000cr.

How to put it?

This number is just stuck in a very ambiguous range.

If they do not pay the money, the other party is estimated not to take "extra" money to subsidize their workers and stimulate them to improve production. I'm afraid it will be difficult for those blue coats to work as hard as they do today, even if they don't work hard.

Do you spend nearly 1000 CR more on the so-called value-added services every day?

Or maintain the current fixed expenditure and reduce the production capacity to the "normal" level?

Chu Guang waited patiently for the logistics section chief to think without urging.

His eyebrows relaxed and wrinkled, and he seemed to have made a judgment in his heart. Li De said with a straight face and staring at his holographic image.

"What about today's value-added services? Do I have to pay you an extra sum of money?"

Hearing this, Chu Guang's face showed a happy smile.

He's a salesman. He knows this very well.

When a customer keeps making inquiries or nitpicking, it shows that he is hesitant. He may or may not buy. The probability is 50-50.

And when the customer put aside the transaction itself and asked about those unimportant gifts, the transaction was basically stable.

Next, we just need to make the customer feel that they have taken advantage of it.

"That's not necessary. Today's six hours are the trial period of value-added services, free of charge."

Li De smiled.

"You taught me a lesson... Are you interested in working in an enterprise? I can write you a letter of introduction and recommend you to enter the management. Seriously, you are inferior in staying in this damn place."

Chu Guang said modestly, "no, I just want my residents to live in this miserable world, so I live more carefully."

I feel a little more comfortable.

Li De sighed, looked at the sky, and slowly nodded his raised head down.

"Deal."

……

The budget of about 1000cr extra expenditure per day is not unacceptable.

After all, the labor cost here is much cheaper than the mechanical cost, and the efficiency of the latter may not be higher than the former in a complex environment.

1000cr is 500 kilograms of grain, or a ton of monosaccharide or polysaccharide that can be synthesized by "consuming some air".

If they need gunpowder rifles, it's even better to deal with the leftover materials from processing parts. The cost is not as cheap as crops that need time to cultivate.

At this time, several soldiers, drivers and engineers of the marine warfare section were coming back from the direction of the shelter camp with their shoulders on their backs and talking and laughing.

"That mutton horn mashed potato is delicious!"

"How did they think of it? They can cook the food with steam! And it's so delicious!"

"From the data, it seems that people ate like this 300 years ago."

"300 years ago?! that was long enough."

"Yes, it's older than the era of prosperity... But I doubt that steaming alone can really kill microorganisms in food?"

"Look at you. The temperature of steam is much higher than that of boiled water!"

"The truth is this... Well, the only problem that can be picked out is that it costs more fuel. First boil the water, and then use steam to heat the food. These blue coat days are very enjoyable."

"Strange knowledge has increased again."

Today's work is over. If there is no emergency, the rest of the time belongs to them.

The most comfortable enjoyment in life is to get off work on time after a busy day, take a comfortable hot bath, then go to the canteen to pick up a cup of synthetic milk or hot cocoa, go to the activity room to play two games of billiards or poker with colleagues, and chat a few words by the way.

By the way, we have to share the joy of tasting delicious food with everyone!

Just need a bucket of instant noodles, you can buy a bowl of fragrant mashed potatoes. It's so affordable!

And there's fish soup with pine nuts tonight! It seems to be called that name.

I don't know what forage those blue coats put in the soup, which makes the fishy and smelly mutant catfish smell less smelly. If you bite it down, you will feel full of collagen. The taste and taste are absolutely amazing!

The food they usually eat is light, less salt and less oil. Although the nutrition is completely sufficient, the taste is always worse.

The "canteen" of those blue coats is good everywhere. The only drawback is that they need to bring their own dishes and chopsticks, and there is no disposable bowl.

But it's nothing to them.

Several people first went to the engineer brother engaged in production in the logistics department for discussion, and soon persuaded the guy with a bowl of mashed potatoes to operate the processing workshop with a flat plate, and gave them several thin steel bowls like paper and spoons for soup.

These steel bowls are not pure steel, but high molecular polymer composite steel. The material is mainly the leftover materials from cutting steel. With some cheap synthetic resin, the cost is very cheap. They all use them as disposable dishes and chopsticks. They throw them away when they use them up. They even save the effort of washing dishes.

"... we are busy outside, but those lucky dogs are sitting in the office blowing the hot air. It's so annoying!"

"Just don't show them off. I'm sorry for the northwest wind we drink today!"

"Agree, you must show off!"

"Hahaha, greedy these dogs say!"

A group of young men reached a consensus and stood on the elevator talking and laughing. It was like finding an oasis in the desert.

Li De, who stood not far away from the statistics materials, and the engineer with the tablet looked confused. They seemed to understand what they were saying, but they didn't seem to understand.

“……?”

“?”
