Doomsday Bunker Upgrade

, The fastest update I can upgrade the latest chapter of the shelter!

"Dididi, Dididi..." Chen Xin opened his eyes and got up from the bed when the alarm sounded.

Brushing his teeth, washing his face, and the separate toilet from wet and dry in the car allowed Chen Xin to even take a shower, but he didn't have this need in the morning and he didn't go into the bathroom.

After finishing personal hygiene, Chen Xin came to the Liulitai, crushed the two energy bars that came with the refuge food, put them into a cup, added a little salt and sugar, and brewed them with hot water. , Serve as your own breakfast.

After eating this semi-liquid breakfast, Chen Xin tasted the semi-salty and unsweet taste of the energy bar in the cup, and couldn't help but muttered: "With less sugar, it seems that you can grow coffee beans and beets in the future."

While muttering these, Chen Xin came to the cab, put the cup in his hand in the cup holder on the operating platform, and opened the map projection on the operating platform, thinking about how to go today.

The city where Chen Xin's home is located is the northern gate of Hunan Province. Leaving the administrative area of ​​this city is equivalent to leaving Hunan Province and entering the boundary of Hubei Province.

Chen Xin is very familiar with this section of the road. After all, in the past, his parents would bring him here every year to soak in the hot springs.

Moreover, the city adjacent to Hunan Province, E Province, is also very famous in history. The "Three Kingdoms Zhou Lang Chibi" mentioned in Su Shi’s famous piece "Niannujiao·Chibi Nostalgia" is located in this city named after this. city.

Speaking of the famous battle of Chibi, apart from this city, it also has a deep relationship with the city where Chen Xin's home is located.

After all, the Yueyang Tower, which has the same name for the ages, was originally the military reading building used by Soochow Lusu to train the navy. The Sanjiangkou where Cao Jun and Soochow Allied Forces fought in the Battle of Chibi was the mouth of Dongting Lake into the Yangtze River, where Jingjiang, Yuanjiang and Xiangjiang converge. The place.

It can be said that the battle of Chibi back then had a deep relationship with these two cities.

However, as Su Shi said in his words, "the great river goes east, the waves are exhausted, the eternal characters", more than two thousand years have already washed away the traces left by the heroes of the past, and now even those inscribed The traces on the rocks have also been covered by ice and snow.

I don’t know if one hundred years later, will anyone still remember that such a legendary war happened under this piece of ice and snow?

This thought came to Chen Xin's mind, but he didn't want to pay tribute to the ancient battlefield. The route he planned was to pass through the urban area of ​​Chibi, and would not reach the ancient battlefield by the Yangtze River.

On the way that Chen Xin was advancing, he would pass by a hot spring resort, which made Chen Xin interested, but also some nostalgia. After all, when his parents took him to the hot spring, he went to that resort.

Just on the way, Chen Xin did not change his direction. After eating the breakfast in the cup, sending the cup back to the counter to clean, and pouring himself a cup of hot water, Chen Xin released the bottom of the car. The auxiliary **** that fixed the body started the engine and moved on.

Due to geological activities in the area of ​​Hubei Province, there are quite ample geothermal resources underground, coupled with abundant water resources, which has created the reputation of the hot spring city here.

If it were in the past, hot springs might be just tourism resources for leisure and vacation, and geothermal development might not have been applied on a large scale due to technical reasons. But in the current environment, a mouthful of hot springs can affect countless lives and deaths.

If a refuge is built around hot springs, water, heating, power supply... can all be solved by geothermal resources. It can be said that as long as the geothermal resources can be used effectively, they can survive the end times.

Thinking of this, Chen Xin couldn't help feeling that there was a large circle of hot springs around his city, but the city he was in did not have hot springs.

Even the hot spring water in his refuge was produced because of the earthquake before. Even if you want to use geothermal resources, there are not enough geothermal resources to use. Only shallow geothermal energy can be used. People have to envy these surrounding cities. Of natural geothermal resources.

However, this also has advantages and disadvantages. The rich geothermal resources also mean that underground magma activities are abundant. The impact caused by meteorite impacts is likely to aggravate geological activities and cause magma eruptions in weak areas on the surface.

For regions rich in geothermal resources, nature also means danger.

Although there are no volcanoes in this generation at the junction of Hubei and Hunan provinces, magma is also likely to form new volcanoes due to earthquakes and other reasons. After all, the volcanic and seismic zones on the Blue Star are highly coincident.

Fortunately, the problem that Chen Xin was worried about did not happen, and he did not see any volcanoes along the way, but when he arrived at the original hot spring resort location, he found out through the radar on the car and the infrared camera of the drone. A refuge built around the hot spring.

"The hot spring refuge? It was really built around the hot spring!" Chen Xin couldn't help but feel a little surprised when he looked at the picture returned by the drone on the monitor.

Although the shelter is built around the hot springs and relies on the original hot spring resort, the surface is still covered with this thick layer of snow, but it is affected by the relatively high internal temperature. The vents and gates of the shelter are located The obvious heat source is very obvious under the infrared sight of the drone.

Looking at the refuge in front of him, Chen Xin did not rush forward. Although he was curious about what the refuge built around the hot spring was like, he did not visit this refuge directly.

He had just set off for a few days, and the supplies in the car were very abundant, and there was no need to supplement supplies.

What's more, even if they need to replenish supplies, Chen Xin still prefers to replenish them after entering the city of Chibi, rather than replenishing them in the shelter in front of him.

So although he is curious about how the refuge in front of him uses geothermal resources, Chen Xin is not the kind of person who will take risks for his own curiosity. After thinking about it, he still gave up on the refuge. The idea of ​​contact.

Moving on along the road, just in case, Chen Xin released a second reconnaissance drone. While allowing the two drones to monitor the situation before and after him, he also opened the console. Next to the radio station.

In this car, Chen Xin installed a high-power shortwave radio. Under good conditions, this radio can transmit signals up to 6000 kilometers away, and he did receive it when he was idle and bored last night. A message in Russian.

Chen Xin didn't understand Russian well. He tried to send a reply in English. The other party seemed to be very excited. He talked a lot, but Chen Xin hardly understood. The two sides talked with each other for a long time. , But it has not established effective communication.

However, Chen Xin could hear that the other party was still very happy to receive the information, and his tone was full of excitement.

As long as the frequency and conditions of shortwave communication are right, it is not particularly difficult to talk to people all over the world.

For example, on the radio station that Chen Xin opened now, what came out was a voice that he could not understand at all, and could not even tell what language it was.

Feeling helpless, Chen Xin adjusted the radio frequency, but no other signals were received.

This made him feel a little regretful, so he could only turn off the radio again and drove on.

The road from this hot spring refuge to the city of Chibi seems to be often passed by vehicles. It should be left by the exchange between the hot spring refuge and the city of Chibi, which also makes the road smooth and easy.

Chen Xin moved along the tracks of the rut, and the speed was much faster. According to his estimation, he might be able to reach the downtown area of ​​Chibi before noon.

Although it is a road, it is actually buried by snow. Even the roadside is flat, and the farmland in the original impression of Chen Xin is completely buried under the snow.

"I don't know if these fields can be planted when the snow melts..." Chen Xin couldn't help but think of this idea, but he quickly lost a laugh.

There is no shadow when the snow melts. Animals and plants are lost in the soil, and the ecological cycle should be gone. Even if the ashes burned by the global fire as an inorganic fertilizer can increase soil fertility, wait until the snow melts. At the time, the snow of more than one meter thick will turn it into a muddy swamp.

Maybe human beings no longer need to cultivate farmland by then? After all, it is a long time to wait until the snow melts. During this time, human beings are affected by the extreme cold and lack of sunlight, and the agricultural production mode should be greatly changed.

After all, agricultural planting now relies on greenhouses and artificial light sources. Even if the light is restored in the future, you can only plant greenhouses on the surface to clean up the snow on the surface. It is not an easy task.

Coupled with the advancement and improvement of human science and technology over a long period of time, it is possible that at that time, humans will adopt more efficient planting methods ~www.ltnovel.com~ instead of traditional farming.

Maybe you can develop in this area?

Chen Xin thought of the upgraded planting greenhouse in his home, and felt that the multi-layer three-dimensional planting system was very valuable for promotion, but he still has no way to replicate this system in other places, and perhaps he can study and study after returning.

He made up his mind, and there were no traces of other moving objects behind him, and Chen Xin also planned to take back the second reconnaissance drone.

However, just when he planned to do this, the sky suddenly lit up. A bright fireball illuminated the dark sky, cut through the sky in the billowing smoke and fell towards the ground.

Chen Xin looked at the huge fireball in surprise. He was stunned by what he saw. He hadn't seen what the sky looked like when it lit up for more than half a year.

However, as the fireball got closer and closer to the ground, he was awakened by the light that gradually lit up in front of him. He hurriedly stepped on the brakes and stopped the car in an emergency. At the same time, he quickly put down the **** under the car, The body is fixed, ready to meet the impact caused by the fire ball falling to the ground.
