North of Qingquan City.

Near the elevated Fifth Ring Road, a team of six people slowly marched along the cold and dead streets against the howling wind.

Originally, there were only five people on the planned trip.

At that time, in the central square of the outpost, Chu Guang brought four heavily armed young players and was preparing to set off. However, before he could get out of the south gate, Luo Hua chased after him and said that he wanted to go together.

As for the reason, it's also very simple -

"There are many possible products of carbon dioxide traps, and the captain asked me to go with you. Although the probability of large-scale storage of dangerous goods in the city is very small, he is still worried that you may encounter danger due to improper operation. ”

Someone offered to help out of kindness, and of course Chu Guang would not refuse.

Although some of his players understand chemical engineering, they don't recognize the words of this world, he is literate, but he can't understand professional symbols.

The blind box of chemicals can not be opened, and it is better to have a knowledgeable person to follow.

And so, the six of them set out on the road together.

It's just that no one expected that on this originally sunny day, it was only halfway to the blizzard.

Recently, there have been more and more days like this.

Chu Guang estimated that when it entered November, the weather in this wasteland would probably be even more exaggerated, and the days would become more and more difficult day by day.

The progress over there in the greenhouse ruins needs to be rushed!

Lao Bai, who was walking in front of the team, raised his head, looked at the sudden expedited snowfall, and couldn't help but empty his eyes.

"The last time I saw such a heavy snowfall was in Harbin City."

"I'm on TV," he said, holding the dawn in his hand, his eyes wandering on both sides of the street, "but I'm more worried about something suddenly coming out of the side than snow." ”

Lao Bai sighed lightly: "To be honest, I miss Ye Shi a little, without his perceptual attributes, I always feel that something is missing." ”

"Plus one, our team has one less eye." Tempest held a short spear in his right hand and scanned the streets on both sides, his nervous look was even more exaggerated than Fang Chang.

I can't help it, I have to be careful.

The two of them are now equipped with one more expensive than the other, and if they are slightly careless, they will be wiped out in waves, and it will be like returning to the pre-liberation period.

This right hand of steel is so awesome that the wind is reluctant to wash its hands now.

Listening to these guys all the way, the edge paddling shouted dissatisfiedly: "Gan! Isn't it enough for me? I'm also a perception department.,And I'm almost at level 7, okay! ”

Tempest: "You're almost a little six." ”

Fang Chang: "Indeed, I'm level 8, the wind is fast, and Lao Bai is about to reach 9." Brother, you have to come on. ”

Edge paddling: "@#%! ”

Walking next to Chu Guang, Luo Hua, who couldn't understand what the shelter residents were talking about, couldn't help but sigh softly.

"I always thought that only indigenous people would speak languages they didn't understand......"

Halfway through his words, he suddenly realized that there seemed to be something wrong with his statement, so he hurriedly added an explanation.

"Well, I didn't mean to be offended, I just thought it was weird. This is because the residents of the general shelter speak a standard Mandarin language, and rarely even have an accent. ”

Chu Guang smiled faintly and didn't care.

"It's okay, I feel as strange as you, why?"

For questions that don't know how to explain, it's good to throw them back as they are, this trick Chu Guang has tried and failed.

Instead of making up an excuse full of loopholes to make others think that you are not sincere enough and have something to hide, it is better to express the same confusion as the other person, and the other person may also stand in your position and help you consider the reason.

Why is the sky blue?

Yes, why, the editor is also very curious, what do you think?

Luo Hua didn't ask, he had seen too many strange things along the way, and this little thing was not surprising at all.

The group quickly arrived at their destination.

It was an abandoned office building, and from the outside, it was hard to tell what it was used for in the pre-war era.

Perhaps it is precisely because of this unsightly appearance that it has been left behind from two centuries of searching.

According to the map given by Captain Lu, the group moved along the edge of the hall, entered the safe passage, and went up the stairs to the target floor.

The hallways were crawling with dark green slime molds, some of which had turned dark brown, and dozens of xenomorph corpses were lying crookedly on the ground.

The xenos here have been emptied, and there are no new xenos roaming around for the time being.

"I'm ...... What is this? "Squatting next to a humanoid xenomorph more than three meters tall, he stabbed it with the bayonet of his rifle with a stroke on the edge.

The dark skin was so stiff that the bayonet poked it like it had hit the tires of a heavy truck, and it couldn't be stabbed at all.

Is this thing really a carbon-based creature?

"Tyrant." Chu Guang glanced at the alien species on the ground, his brows furrowed slightly, "There is actually such a monster on the Fifth Ring Road. ”

"Your Excellency, is that tyrant difficult to deal with?" Fang Chang looked at him and asked.

"It's not easy to deal with," Chu Guang thought for a while and said, "If you encounter it in this kind of terrain, a team like you can probably wipe out two." ”

Actually, he hadn't seen it.

But there's nothing wrong with blowing to death.

Fang Chang swallowed, the wind shrunk his neck, Lao Bai and the edge of the stroke didn't feel anything, their equipment was now at the level of a whiteboard.

To die is to die.

Bypassing the corpse of the tyrant, Chu Guang led the group through the alloy gate that said "Idle people are forbidden to enter" and came to the inside of the carbon dioxide trap.

It's a lot of space, taking up almost half of the entire floor, and opening up the space on the upper floor.

The carbon dioxide produced by the entire building is sent here through a central ventilation system, where it is broken down into graphite and oxygen as needed, either by adding hydrogen or replacing it with hydrogen.

For the people of that era, the atom was like a toy in their hands, with an almost endless amount of energy enough for them to squander and transform the creations of nature into what they needed.

And those that are produced are packed in special boxes, stacked next to special freight elevators, waiting for the staff who will never come to transport them.

Looking at the hundreds of large and small squares piled up in the room, Chu Guang roughly estimated that there were about three or four hundred cubes.

He couldn't help but ask.

"Haven't you captains been curious, what are the contents of those boxes?"

"There's no need to be curious, as long as there is enough energy, we can do it, at most it is a matter of cost...... For example, this row of black boxes looks like graphite, so it seems that your luck is not very good. ”

Luo Hua laughed and walked over to the other row of boxes.

Holding a flashlight on it, he read the text on it and continued to comment with interest, "This is okay, it's a bunch of polymer fibers...... Look at the label is X-4. ”

“X-4？”

"A kind of numbering, after all, their spatial structure is complex and bizarre, and we can't always use chemical formulas to represent them." After a pause, Luo Hua continued, "By the way, although its main use is to make clothes, if you need it, you can also use it to replace the wood fibers in smokeless gunpowder, and the detonation speed and power can be increased by at least 20%...... That's what we did. ”

It's much easier to understand.

In terms of the game, it is - [rifle ammunition power +20%, chamber explosion probability +?] 】

Chu Guang silently noted down its purpose, and glanced at the number of similar boxes, which looked like there were about forty or fifty.

At the end of the year, it is estimated that there are twenty or thirty tons.

Looks like it's been enough for a long time.

At this moment, Luo Hua, who was walking in front, suddenly let out an exclamation.

"Holy?!"

Chu Guang, who was interrupted from his thoughts, raised his head and immediately walked to his side, and the four little players who thought that the plot had been triggered also followed and leaned their heads over curiously.

"What's going on?" Chu Guang asked for them.

"Dilart rubber!"

Looking at the unsightly gray box in front of him, Luo Hua took a deep breath, looked incredulous, and said with envy in his eyes.

"How did this thing end up here?! It's so unusual! ”

Chu Guang: "Is there any problem?" ”

"Absolutely! The products of carbon dioxide traps are mainly determined by the industrial demand of the region, and starch, graphite, and polymer fibers are generally more common, and olefins, alkanes, and even benzaldehydes and ketones may appear near industrial areas. But Dilat rubber ...... I've only seen it near the Aerospace Industrial Park, so is there an aerospace industry in Qingquan City? ”

Taking a deep breath, Luo Hua made a summary.

"In a word, you're rich!"

Dilat rubber, a composite nanomaterial formed by the chemical bonding of organic and inorganic components at the molecular level.

Yes, it is not a simple organic component, it cannot be synthesized by relying solely on carbon dioxide and water, and other substances have to be imported into the reaction system, which can be sold for a lot of money even in Ideal City.

That's why Luo Hua was so surprised.

In an anaerobic environment, its molecular structure folds and arranges, and it exists macroscopically in the form of a gelatinous liquid. Once it encounters oxygen and is at room temperature, it will be converted into a solid state in a short time, and the molecular structure will also change, showing a crystal-like form.

It's like cement that has undergone a hydration reaction.

This process is usually irreversible due to changes in molecular composition.

This material has excellent wear resistance, acid and alkali resistance, and has almost metal-like resistance to high temperatures, and is not as easy to age as traditional rubber, which is extremely rare in traditional polymers. It is precisely for this reason that it is commonly used as an aerospace material.

Chu Guang: "Can you produce it?" ”

The expression on Luo Hua's face was slightly embarrassed. After all, I just pretended to be forced just now, but I was slapped in the face in less than two minutes.

Coughing slightly, he tried to explain.

“…… It's not strictly a hydrocarbon! It also contains a lot of inorganic components, which is equivalent to an organic/inorganic hybrid polymer. ”

Chu Guang nodded thoughtfully, and tried to translate the words that he didn't understand.

So it shouldn't be able to be produced.

"According to a conservative estimate, there are about fifty tons of ...... here," Luo Hua looked at the situation in the warehouse with envy on his face, and said with emotion, "You must not let our section chief know." ”

"Why?"

"I'm worried he'll have insomnia."

“……”

As for such an exaggeration?

Chu Guang felt that if Li De wanted it, he would not be so stingy that he would not give it at all.

It's just that it's such a long way to get from here to the camp, and you have to move the goods down the stairs......

It's not too much to charge for shipping, right?

In short, according to Luo Hua, Dilat rubber is very versatile and valuable. Chu Guang tried to understand that its position in the rubber industry is probably similar to perfluoroelastomer in the early 21st century?

And there is no such thing as "difficult to process".

Before it encounters oxygen, it can be kneaded at will like glue, and there is no rubber material that is easier to handle than it.

By the way, due to its good sealing performance, it is widely used in aerospace, nano devices, bionic engineering, mechanical seals and other industries.

For example, the power armor produced before the war was used in this material!

Of course, its use is not limited to this, many industrial production equipment will use rubber, if it can be replaced by Dilat rubber, maintenance costs will be greatly reduced, production efficiency can also be greatly improved.

With these good things, the industrial area of the outpost will not have to worry about rubber for a while.

Of course, with so many boxes, it is impossible for only six people to move them back.

So, Chu Guang immediately updated a delivery task on the VM-

[Mission: Move the goods from the designated location back to the outpost (recommended power system)]

[Reward: 10 silver coins per chest, 10 contributions]

Now that there is less and less work on the side of the action camp, Chu Guang always has to find something to do for these energetic little players......

……

After returning to the outpost, Luo Hua returned to the office and packed his belongings with his partner Ace.

The Trailblazers are leaving the day after tomorrow, and their work here is over, and a car will pick them up before the evening.

Thinking that this drinking friend, who had just become familiar with him, was about to leave, Chu Guang couldn't help but feel a little sad, so he returned to the shelter, selected a bottle of red wine with gold paint from the old leech's collection, and brought it to the temporary office.

"Thank you for this time, I don't have anything good to give you here." Stuffing the red wine into Luo Hua's hand, Chu Guang looked at him sincerely and said, "This bottle of wine should be regarded as a gift for the canton, remember not to drink it at work." ”

"Thank you, your friendship is the most precious gift for me!" With a touched face, he took the red wine from Chu Guang's hand, Luo Hua rummaged in his pocket for a while, and his face was embarrassed, "...... Damn, I wasn't prepared at all. ”

His pockets were cleaner than his face.

There were still a few bills before......

"It's okay, your friendship is equally precious to me," Chu Guang smiled and said, "When your Journey to the West is finished, just send me a copy." ”

"That's a must! But it's different, I have to give you something......" Luo Hua pondered for a while, and suddenly his eyes lit up, "There is!" Let me write a letter for you. ”

Chu Guang gave him a strange look.

"Write a letter?"

Luo Hua immediately nodded and said excitedly.

"That's right, I have a drinking buddy on the East Coast, and he's not as good a drinker as I am! Of course, it's not just drinking, he's an engineer...... Although I can't remember the name of the thing he studied, I always heard him complain that life in Ideal City was too boring, and he envied those of us who were lucky enough to embark on a journey for the future of human civilization. ”

"When I get back on the Trailblazer, I'll write a letter to him and recommend him to come to you!"

Chu Guang always felt that this guy was a little naïve.

Where is that kind of complaining, obviously Versailles?

But out of politeness, he smiled and nodded.

"Then I'm looking forward to your good news."

Luo Hua grinned, patted his chest and packed the ticket.

"Don't worry! I'm reliable! ”

Ace, who had already packed his luggage next to him, glanced at this guy.

If Chu Guang was not mistaken, it should be a slap in the face......
