Doomsday Bunker Upgrade

"DiDi, DiDi..." The alarm clock sounded, and Chen Xin opened his eyes and got up from the bed.

Brushing his teeth, washing his face, and the separate wet and dry bathroom in the car allowed Chen Xin to even take a shower, but he didn't go to the bathroom without such a need in the morning.

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

Eating this semi-liquid breakfast, Chen Xin tasted the half-salty and not sweet taste brewed from the energy bar in the cup, and couldn't help but mutter: "I put less sugar, it seems that I can grow some coffee beans and beets in the future."

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

The city where Chen Xinjia is located is the northern gate of Hunan Province. Leaving the administrative scope of this city is equivalent to leaving Hunan Province and entering the boundary of Hubei Province.

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

In addition, the city of E Province, which is adjacent to Hunan Province, is also very famous in history. The "Three Kingdoms Zhoulang Chibi" mentioned in Su Shi's famous poem "Nian Nujiao: Chibi Nostalgia" is located in this named after this. City.

Speaking of the famous battle of Chibi, not only is it related to this city, but also has a deep relationship with the city where Chen Xin's family is located.

After all, the Yueyang Tower, which is also famous through the ages, was originally the military parade building used by Lusu in the Eastern Wu Dynasty to train the navy, and the Sanjiangkou, where the Cao Jun and the Eastern Wu Allied Army fought fiercely in the Battle of Chibi, was the mouth of the Dongting Lake into the Yangtze River, where the Jingjiang, Yuanjiang and Xiangjiang rivers meet. The place.

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

However, as Su Shi said in his words, "the great river goes east, the waves are washed away, and the romantic figures of the ages", more than 2,000 years have already washed away the traces left by those heroes and heroes in the past, and now even those inscribed The traces on the rocks have also been covered with ice and snow.

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

Chen Xin had such an idea in his mind, but he didn't have the idea of ​​paying 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 other hand, Chen Xin would pass by a hot spring resort on his way forward, which made Chen Xin involuntarily interested, but also had some nostalgia. After all, when his parents brought 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, he sent the cup back to the washing machine to wash it, and poured himself a cup of hot water. Chen Xin released the bottom of the car. The hoe that fixed the body, started the engine, and moved on.

Due to the geological activities, there are abundant geothermal resources underground in this area of ​​E Province. Coupled with the abundance of water resources, it has created the reputation of the city of hot springs.

If it was in the past, hot springs may only be a tourist resource for leisure and vacation, and geothermal development may not be applied on a large scale due to technical reasons, but in the current environment, a sip of hot springs can affect countless lives and deaths.

If a shelter is built around hot springs, water, heating, power supply... all can be solved with geothermal resources. It can be said that as long as geothermal resources can be effectively used, they can survive in this apocalypse.

Thinking of this, Chen Xin couldn't help but sigh that there is a large circle of hot springs around the city where he lives, but there is no hot spring in the city where he lives.

Even the hot spring water in his shelter was produced because of earthquakes before. Even if he wanted to use geothermal resources, there were not enough geothermal resources to use, so he could only use shallow geothermal energy, which made people envious of these surrounding cities. natural geothermal resources.

However, this also has advantages and disadvantages. The abundance of geothermal resources also means that the underground magma activities are relatively abundant. The impact of meteorite impacts is likely to intensify geological activities and cause magma eruptions in weak areas on the surface.

This naturally also means danger for geothermal-rich regions.

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

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, through the radar on the car and the infrared camera of the drone, he found A sanctuary built around a hot spring.

"Hot Spring Refuge? It's really built around hot springs!" Chen Xin couldn't help feeling a little surprised when he looked at the picture sent back by the drone on the monitor.

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

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

He had just set out for a few days, and the supplies in the car were very abundant, and he did not need to replenish the supplies.

What's more, even if he needs to replenish supplies, Chen Xin is more inclined to replenish after entering Chibi urban area, rather than replenishing in the refuge in front of him.

Therefore, although he is curious about how the current shelter 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 with this shelter. Contact ideas.

Continue along the road, just in case, Chen Xin released a second reconnaissance drone. While letting the two drones monitor the situation before and after him, he also turned on the console. radio station next to it.

In this car, Chen Xin installed a high-power short-wave radio. Under good conditions, this radio can transmit signals up to 6,000 kilometers away. When he was idle last night, he did receive it. A message in Russian.

Chen Xin didn't understand Russian very well. He tried to send a reply in English. The other party seemed to be very excited and babbled a lot, but Chen Xin could hardly understand it. , but did not establish effective communication.

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

As long as the frequency and conditions are suitable for short-wave communication, it is not particularly difficult to communicate with people all over the world.

For example, on the radio that Chen Xin has opened now, there is a sound that he can't understand at all, and can't even tell what language it is.

Chen Xin felt a little helpless and adjusted the frequency of the radio, but no other signals were received.

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

The road from this hot spring sanctuary to Chibi urban area seems to be often passed by vehicles, which should be left by the communication between this hot spring sanctuary and Chibi urban area, which also makes the road smooth and easy to walk a lot.

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

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

"I don't know if these fields can still be planted when the snow melts..." Chen Xin couldn't help but have this idea in his mind, but he quickly burst into laughter.

When the snow melts, there is no shadow. The existence of animals and plants in the soil is lost, and the ecological cycle should be gone. Even if the ashes of the previous global fires can be used as an inorganic fertilizer to increase soil fertility, wait until the snow melts. At the same time, this meter of snow will turn this place into a muddy swamp.

Maybe by then, humans will no longer need to reclaim farmland? After all, it is a long period of time until the snow melts, and during this time, humans are affected by extreme cold and no sunlight, and agricultural production patterns should change greatly.

After all, agricultural planting now relies entirely on greenhouses and artificial light sources. Even if the light is restored in the future, if you want to cultivate on the surface, you can only rely on building a greenhouse and clearing the snow on the surface. It is not an easy task.

Coupled with the progress and improvement of human technology over a long period of time, it may be that humans will adopt more efficient planting methods at that time, rather than traditional farming.

Maybe you can develop yourself in this direction?

Chen Xin remembered the upgraded planting greenhouse in his home, and felt that the multi-layered three-dimensional planting system was very valuable for promotion, but he still has no way to replicate this system in other places. Maybe he can study it after he goes back.

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

However, just when he was about to do this, the sky suddenly lit up, and a bright fireball illuminated the dark sky, pierced the sky in the billowing smoke and dust, and fell toward the ground.

Chen Xin looked at the huge fireball in surprise. He was stunned by what he saw in front of him. He had not 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 also awakened by the light that gradually brightened in front of him. He hurriedly stepped on the brakes and stopped the car in an emergency. The body is fixed, ready for the impact of the fireball falling to the ground.

Fire from the sky, no prize quiz
