Today's natural rubber has footprints all over any human industry.

And in the near future, we may bid farewell to the era of natural rubber.

In the next two months, global rubber will usher in an early tapping period, when the output of the rubber industry will show a bright future.

Since then, natural rubber has suffered from freezing damage due to rubber trees, and there has been little production.

The association hereby requests and appeals for assistance from all walks of life. We need a plan to help the rubber tree survive the crisis, so that this great material can still be alive after the Little Ice Age! 】

This statement was quickly circulated by high-level officials from various countries.

Almost everyone shook their heads and sighed.

Berry Country Capitol.

It's outrageous. Seeing this joint statement, I frowned.

According to statistics, the monthly consumption of natural rubber in Berry Country is about 700,000 tons, while the domestic production of Berry Country can only meet about [-] tons of it.

In other words, the remaining 600,000 tons must be imported from all over the world.

One of the largest exporters of natural rubber in Asia is Raspberry.

The rubber industry has been hit hard, and it will also affect the development of Berry Country's next plan.

"Damn it, what the hell are Dragon Kingdom and the others planning!"

"Why didn't they summon at all!"

"Their people look relaxed, busy with their own affairs, not worried about the Little Ice Age two months later, let alone the sun going out!"

Seeing that the commander was furious, Ain and the others did not dare to speak, and silently lowered their heads to bear it.

The outrageous eyes were compelling, and he said without hesitation: "In this case, in the next two months, we will step up pressure on other countries, list natural rubber as the highest level of combat readiness materials, and hoard them in large quantities!"

"The reason why Berry Country is strong is that the whole world is its warehouse and factory!"

These words made everyone present feel a sense of pride.

Te outrageously patted the table and said with a sneer: "Heh, in the apocalyptic era, the strong prey on the weak. Berry Country has been the overlord for so many years. Under my leadership, it will continue its glory until...human beings civilization extinction

When the whole world is panicking because the rubber trees will be wiped out in the severe cold, the people of the Dragon Kingdom are at home, packing up their belongings.

Although the Crisis Bureau has not yet issued a national relocation order, the sudden southern census, numbering, and the withdrawal of some elite forces from the construction of the underground city to build temporary housing... Various behaviors herald the news , is already on the verge of coming out, just short of the official announcement of the crisis situation bureau.

And when the joint statement "The era of natural rubber is coming to an end, more than 300 years of history has come to an end" spread to China.

People yawned and said calmly:

"Rubber is of course very important, but our Dragon Kingdom should have figured out a countermeasure long ago."

Someone said: "We are not worried. Even the Little Ice Age, the extinction of the sun and other horrific disasters, the country has already taken preventive measures. It is just a tree. What are we worried about!"

Someone said: "I believe in the country! Dragon Kingdom has already made a perfect plan!"

A practitioner in the automotive industry made a statement, saying:

"In fact, our country has been looking for a substitute for natural rubber since more than ten years ago."

"The reason is very simple, because we are too dependent on natural rubber. We only account for 40.00% of the global rubber output value, but consume [-]% of raw materials. We were originally the world's largest natural rubber demander!"

"However, in the past few years, Longguo has successively launched national key special projects such as the 'New Functional Compound Elastic Preparation Technology Emergency Rubber Substitution Project' and so on!"

"In the past two years, these projects have achieved results. The rubber forests in Xishuangbanna and other areas have been eradicated and returned to the forests. The measures such as returning rubber trees to forests' have shown that the demand for rubber in Longguo is decreasing. Small!"

"So trust the country! Rubber tree, it's just a tree, no big deal!"

now.

In the Office of the Chief of the Security Bureau Building, Xu Qiu, Zou Botao and the others laughed dumbfounded when they saw the reaction of the people.

Zou Botao was in a very good mood, and said with a smile: "The people have confidence, so why worry about no power in this country?"

Lu Guangyuan said respectfully: "Over the past few days, Director Xu has built up infinite confidence in our people, so that they will not worry about any difficulties, even if it is a disaster that will destroy the world!"

"Because behind them, there is a dangerous situation, and there is this powerful Dragon Kingdom!"

Xu Qiu relaxed, leaned on the back of the chair, and said: "I am also very fortunate to be born in the Dragon Kingdom and become a member of the Dragon Kingdom. I am also honored to have such people and work with you!" Zou Baitao, Lu Guangyuan and others People bowed and bowed to express their gratitude and respect.

After a while, Xu Qiu sat upright, took a sip of tea, and said leisurely: "Rubber is an important raw material, and it plays an important role in automobiles, ships, and various types of machinery."

"Our migration plan is mainly aimed at virgin forests, and all kinds of tree species with ecological value, such as rubber trees, palm palm trees, camellia oleifera, etc., will be excluded."

"They mainly produce economic benefits, but they don't have much value for ecology, climate, and preventing soil erosion."

"And in the coming time, economic benefits will be the least important thing."

"And the sunlight, oxygen, and moisture that we humans rely on for our survival will become luxuries, and these are the three main problems that we need to solve in the construction of underground cities."

"The forest is a natural oxygen plant and a purifier of the air. At the same time, it can also accumulate soil moisture, etc. In the construction of the underground city, this is the necessity of dividing the forest ecological zone. Economic forests, etc., are not considered for the time being."

°Xu Qiu thought for a moment and said, "In the next eleven months, we must find raw materials that can completely replace natural rubber!"

Zou Botao said: "As ordered, I will interview the relevant departments today and urge them to speed up the development and search of rubber substitutes. Please rest assured, Director Xu!" Xu Qiu nodded, leaned back in his chair, and began to close his eyes and rest.

Seeing this, Li Bingqing winked at Zou Botao and Lu Guangyuan. They understood, and left the office lightly, for fear of disturbing Xu Qiu's rest.

"Director, be careful of catching a cold."

Li Bingqing brought a thin blanket and gently covered Xu Qiu's body, reminding him gently.

Looking at this young helmsman, Li Bingqing had mixed feelings, and his eyes were full of distress and admiration.

Dragon Kingdom, Tiandu No. [-] underground city.

After transferring one-tenth of the personnel to the nearby residential area to build temporary housing, the speed of the dungeon construction has not slowed down.Two days ago, Tiandu No. 50 Dungeon finally reached the depth of [-] meters underground, and began to "hollow out" this area.

This construction method is actually very simple. It is to dig a shaft in a selected area, and then hoist personnel and equipment into the shaft. The construction workers dig out an "underground palace" like a pangolin.This is the dungeon.

According to the original plan, this project required the use of a shield machine.

The shield machine was originally an underground giant in the excavation of subway tunnels. The cutter head at the front is like a big steel tooth, which is responsible for digging and digging in, and the transportation channel for eating soil at the back is responsible for transporting the muck out.

In fact, this excavation process is quite slow.

Every meter that the shield advances, it will cost the construction workers a huge amount of money.

While the shield machine is digging, the engineers must install the concrete segments at the same time.

It takes dozens of people several hours to assemble a ring of segments, and the dungeon with a total area of ​​more than 100 hectares takes an astonishing amount of time!

In the previous plan, the construction of the dungeon only needed to dig out the area of ​​a granary.

But now, with the advent of the Little Ice Age, construction workers had to abandon the sophisticated and time-consuming shield machines and adopt more primitive methods to carry out the project.

That is to say, use machinery and manpower to dig out the area of ​​a forest square meter by square meter.

At this moment, in each construction site, different machines are running vigorously, and the workers are in full swing, transporting soil and shoveling stones, with enthusiasm!

Excavators, loaders, cutters, mixers, and cranes are running on the construction site. Above these heavy machines is 50 meters of land, and above the land is the surface.As the dirt is excavated, more and more space is excavated.

Yang Jian, a volunteer from Tiandu Sports University, was looking worriedly at the stratum more than ten meters above his head, and asked: "Brother, we have dug such a large space underground, the soil above will not Did it fall?"

The construction workers wearing yellow hard hats listened and said proudly: "Of course not!"

This old worker who followed the foreman all over the country was very happy to be called "big brother" by a college student.

He explained: "I don't know how to build a dungeon, but ah, let's take the subway."

"The design and construction of the subway must ensure that the ground settlement is within the scope required by the code. As long as the design is correct and the construction methods are correct, then there is basically no possibility of collapse!"

"And the underground city is an even greater project. How could Director Xu fail to consider this point. He definitely added the soil pressure, upper load and other loads in various places before starting the construction!"

Yang Jian suddenly realized.

Sure enough, professional things still need professional personnel!

However, he still has a problem.

Yang Jian touched his chin and asked suspiciously: "However, after the sun goes out, the entire surface of the earth will freeze, and the falling snow will thicken the ice layer, making the ground heavier and heavier. At that time, there will be a collapse accident. ?"

The old worker stretched out a finger, shook it, and said confidently: "At that time, it will be even worse!"

"Think about it, the current soil is still soft in comparison, even under such circumstances, the dungeon will not collapse!"

"And after the sun goes out, the temperature drops, and the soil freezes and becomes permafrost."

"The characteristic of permafrost is hard and compact. At that time, the 50 meters of soil above our heads had already been firmly frozen together, like a whole, and it would have a very amazing load capacity, almost There is no way a collapse accident will happen!"

Yang Jian completely understood this time.

Excavating, supporting, and building, they are about to carve out a huge dungeon!

He looked at the construction site, where cranes, winches, forklifts, commercial platform trucks, compactors, etc. carried the excavated soil and transported it back to the ground.

And the response team on the ground will drive the forklift to send the soil and stones to farther places.

In two days, this area has opened up an area of ​​nearly [-] square meters.

However, this area is still too insignificant for a dungeon of [-] square kilometers.

The person in charge of the construction team is standing at the construction site, directing various mechanical operations. He has a blueprint in his hand. This blueprint needs to open up an area of ​​about ten hectares for the migration of forest resources.

That is one hundred thousand square meters.

This area is not large, however, there are a thousand underground cities in the whole country.

Some of the non-cold-resistant tree species in the south will be transferred to the nearby underground city, while other trees with strong adaptability and not easy to die during transportation will be transported to the northern underground city.

Thanks to the natural heat preservation conditions of the underground city, these trees, even during the Little Ice Age, the underground temperature will remain above zero, at least five to six degrees Celsius.At this temperature, most of the tree species that are not cold-resistant can survive.

He crossed his hips and looked proudly at the construction site ahead.

This area happened to be dug out to the side, and the subsequent construction of the dungeon would not be hindered by the dense forest.

Even, because of the existence of the forest, construction workers can take a walk in it to cultivate their sentiments.

Thinking of this, the corner of the person in charge's mouth curled into a smile, he felt so shocked.

Director Xu's plan is simply an unprecedented and unprecedented strategy!

If there is no confidentiality requirement, the person in charge would like to yell out to let the workers below know this exciting news!

After all, when he made several tours and visited workers, he heard many people express their concerns about forest resources and how the forests in the south could survive the severe cold of tens of degrees below zero.At that time, he really wanted to tell this group of people, don't worry about it, the country has already made all plans!

However, he can only shut up and bury the secret in his heart!
