However, the usual way is to fight against the low temperature of minus five or six degrees at most, which is already an extremely low temperature for a tropical country like Malaihua.

However, during this time of the Little Ice Age, the temperature in Malaijuya will drop to about ten to twenty degrees below zero...

A country that has never experienced cold protection suddenly has to face severe cold across the country.

The rubber tree will die at five degrees above zero.

How can you keep it?

Forest greenhouses are useful in theory, but there are two fatal problems.

First, there is no experience in code to attract Asia.

In the past, the growers of Yaliya used to prevent the growth of rubber trees from being too high. Who would have expected that they would have to prepare for the cold today.

Second, costs are not directly proportional to benefits.

Building a forest greenhouse requires a lot of loss. Even if the rubber trees can be preserved, so what?

Let the rubber trees live until October, when the peak production period is reached, a large amount of high-quality rubber can be harvested, but after harvesting one crop, the next harvest will be in October next year.However, the sun will go out next June.

Moreover, the forest greenhouse may not necessarily be successful.

Using forest greenhouses with very high cost and unpredictable success rate to bet on the high production of rubber trees, it is better to harvest the rubber trees at the initial production stage before the small glacier.This is the most economical and most reasonable approach.

The atmosphere fell into dead silence, and there was no way to break the situation.

At this time, the director of the Rubber Bureau stood up and proposed: "Master Commander, can we follow the example of Longguo and move the rubber trees underground?"

The director of the Small Rubber Plantation Production Management Bureau shook his head and said, "That's impossible."

"Rubber trees like high temperature and humidity. The required annual average temperature is about 25 degrees to [-] degrees. Moreover, the annual average precipitation needs to be between [-] milliliters and [-] milliliters..."

"Transferred to the ground, let's not talk about how huge this project is, whether Malaisuya can sustain it."

"Even if it is really successful, how can we guarantee the high temperature and high humidity requirements of rubber trees underground?"

"In the closed underground, how to ensure the large amount of oxygen needed by rubber trees?"

"The rubber tree is also a tree species that likes strong light. If it is really transferred to the ground and artificially provides these cultivation and growth conditions, the cost paid is not as good as the benefits brought by the rubber tree." Ma Jilong was upset and said: "We It is impossible to migrate."

"First of all, Dragon Kingdom was able to carry out this plan because they were already constructing dungeons, and now they just included forest resources by the way."

"If we want to follow suit, we have to add additional excavation projects and dig out a special underground space for rubber trees. Is this possible?"

He sighed heavily.

Now the domestic situation is grim, and even human life may not be saved, so how can I care about rubber trees.

"I know that many people present have their own rubber industry, and rubber is almost linked to your assets."

"I didn't care about this before, but it doesn't mean I don't know!"

"During the Little Ice Age, not only the rubber trees were affected, but even our citizens may freeze to death, so restrain yourself and hide your thoughts."

"From now on, the country will begin to tap rubber for the first time. Before the Little Ice Age comes, all rubber trees will be cut to minimize losses as much as possible."

"At the same time, start preparations for the national cold protection plan."

The hearts of the people were awe-inspiring.

It's time to change the world...

On the last day of July, at this night, Longguo was brightly lit, and a large number of trucks and trains carried trees and rushed to the nearby underground city, and even further north.On July 31, at 13:[-] p.m., the NO.[-] underground city in Sichuan Province.

This underground city is close to the southwest forest area. After a large number of tree species are excavated, they will be transported to dozens of underground cities in Sichuan Province.

At the same time, the provinces of Yunnan and Tibet are also receiving tree species in the southwest forest area.

As the Southwest Forest Region, the second largest forest region in Longguo, the forest ecological area of ​​the underground cities in the three provinces is far from enough.

Therefore, except for these three provinces, all provinces in the Southwest have the task of receiving tree species exported from the Southwest Forest Area.

Eight thirty in the evening.

It has been an hour and a half since Longguo announced the start of the forest transplanting plan.

At this time, the first batch of tree species from the southwest forest area arrived at the NO.13 underground city in Sichuan Province.

The local person in charge, Wang Gang, came to greet him in person.

There are also reporters, media and so on.

As the first dungeon in the country to accept tree transplanting, the No. 13 dungeon in Sichuan Province is now attracting the attention of the people of the whole country and even the whole world.

"Hello, everyone. I'm Zhang Yang, a reporter from the main station. I'm in Sichuan Province. Behind me is the first dungeon that received transplanted trees from the forest area!"

A fair-skinned, slender female reporter smiled cheerfully at the camera. She had a face of first love, with delicate features and gentle manners.

"Standing next to me is Professor Wang Gang. Professor Wang is the chief designer of Tianfu Square in Sichuan Province, and also the chief engineer for the renovation of Yuewang Building! Professor Wang is well-known in the architectural circles at home and abroad!"

"Professor Wang Gang once met Director Xu, he is the person in charge of the dungeon personally appointed by Director Xu!"

When these words were spoken, the eyes of the people around showed envy.

Wang Gang showed a refined smile, and said, "It's a great honor to have Director Xu's trust. Wang will definitely do his best to build this underground city in Sichuan Province to everyone's satisfaction!"

Rumble.

In the distance came the roar of a truck engine.

Wang Gang turned his head and looked excitedly, and said: "The members of our forest ecological zone have arrived, the tree species from the southwest forest zone!!"

One after another, trucks entered from the entrance of the dungeon, which was more than 20 meters wide, and went all the way down into the dungeon.

Reporter Zhang Yang had an unconcealable pride in his eyes, and said, "This is our Dragon Country!"

"In ancient times, the Foolish Old Man moved mountains, but today, all the people of the Dragon Kingdom transplant forests!"

In the shot, the truck is loaded with tree species and rushes to the forest ecological area of ​​the underground city.

There is a regular ball of soil at the bottom of each tree, which is covered by a cloth net to prevent the soil from falling and exposing the root system.

It was already [-]:[-] at night, and most of the Long Country was already dark. However, construction lights were everywhere in the underground city.

White, yellow, all kinds of lights illuminate the faces of the roadside workers.

These simple laborers are now excitedly watching the fully loaded cars drive past them. In the next few months, these trees will witness the birth of the dungeon with them!

Zhang Yang reported to the camera: "Friends in the audience, this is actually the first time we have seen the prototype of the Dragon Kingdom dungeon. You see, the area where each truck is driving has completely been turned over. There's a pothole, and that's the forest biome!"

"And our dungeon construction area is on the other side of the forest ecological area, so even if the forest ecological area is full of trees, the construction of our dungeon will not be affected in any way!"

"These forests will become the green embellishment of our dungeon in the future. Even if you live in the dungeon, everyone can come here for an outing!"

The camera rotated slowly, taking in the prototype of the entire dungeon.

Behind is the forest ecological area, a long queue of trucks driving to the end of the forest ecological area, preparing to plant tree species in sequence from far to near.

Under the command and assistance of the forestry personnel, the workers unloaded the trees one by one from the truck, and then lifted the thick trees with the help of a crane and put them into the pothole.

The camera shifted again to the dungeon construction area.

Greenhouses have been set up one by one on the construction site, and these are the residences of the construction workers of the underground city.

On the top, there are several huge ventilation facilities, which are all set up to ensure the air circulation in the underground city.

In the future, the underground city will adopt the structure of its own air circulation and be completely isolated from the surface.

However, these advanced air circulation structures can only be laid in the later stages of the dungeon construction.

Just like repairing a house, the house must be repaired, and then the water and air will be ventilated.

If the house is still laying the foundation, it is obviously unreasonable to suspend the water pipes and wires of the house in advance.

And farther away, there is endless darkness, over there is the dungeon area that is being developed.

These places will need to be developed with high-tech machines such as shield machines, and the development work will also be carried out together with the forest transplanting plan.The people of Dragon Kingdom are in shock.

"Is this our dungeon? It's endless at a glance, it's too wide!"

"This is just the beginning of the construction of the dungeon, and the border is no longer visible. If the dungeon is completed, how big it will be!"

"Damn it! I thought it was a cramped and narrow space like our basement! So it's so big!"

"Living in the dungeon is no different from the ground!"

"I have full confidence in our country's dungeons! Long live the Dragon Kingdom!"

"In the future, you can still breathe the fresh air of nature in the dungeon. Just thinking about it will make you feel comfortable. This is really not much different from the cities on the ground!"

All the major media released news one after another.

[Longguo Xinhua News]: "The underground city of Sichuan Province is the first to receive transplanted tree species from the southwest forest area, and everything is going well! Longguo's forest transplanting plan is sure to be a great success!"

[Sichuan Provincial Daily]: "The underground city of Sichuan Province is fully prepared to welcome all the transplanted trees from the southwest forest area and the surrounding small forest areas. It will not disappoint Director Xu's entrustment!"

[Tiandu Daily]: "Our city has completed the development of forest ecological zones in several underground cities, and we are ready to welcome the workers from the Ministry of Forest Transplantation and Transportation! We are waiting for your arrival!" In cheers.

This night, countless people had such a dream.

After the sun was extinguished, the blue star was frozen, and above the surface, there was a constant wind blowing all day long.

This strong wind also carried ice slag, skipping the frozen Pearl Tower of Shanghai, the white Great Wall, the snow-capped and frozen Wuyue Mountains and the Yellow River and Yangtze River.

The whole world has turned into ice and snow.

The Statue of Liberty in Berry Country was frozen, and the torch became an ice sculpture forever.

Countless icicles hang down from the Leaning Tower of Pisa.

The Bali Iron Tower was crushed by thick ice and snow, and the ruins became part of the glacier.

In the monastery, countless people hugged each other and died under the statue of the Virgin...

And in the dungeon of Dragon Kingdom, people raised their wine glasses to celebrate the annual Spring Festival.

Some people travel to other dungeons, from the Canton dungeon in the south to the dungeons in the frontier, to see the appearance of the cattle and the Tibetan antelope.

Some people stayed in their own dungeons, went outing in the forest, went fishing in the lake, and gathered in the entertainment center, counting down the countdown together, watching the fireworks exploded in the holographic projection in the sky

At this time, a reminder from the Emergency Bureau sounded on the radio: "This year's sub-zero temperature on the surface has reached 230 degrees, and there are too many extreme weather. Please travel inside the dungeon. Unless there are special circumstances, do not go to other dungeons."

Countless people smiled in their dreams.

Such a scene is so warm, so comforting, and so intoxicating.

Ten o'clock at night.
