Doomsday Bunker Upgrade

　　 trembling fingers opened the album, which contained old and yellowed photos.

　　 Most of these old photos are photos taken by Chen Xin’s parents when they were young, because afterwards, when Chen Xin was studying at the university, the digital camera became popular, and it was no longer popular to keep photos.

　　 gently stroking these photos, watching the energetic and vigorous parents and the self, who was just a kid, more tears on Chen Xin’s face.

　　 Everything in the photos has long since become memories, and even the places where these photos were taken no longer exist and are hard to find. I have grown up to the age of the parents in the photos, and my parents are already gray-haired and old.

　　 The child wants to raise up but does not wait for relatives. There is no greater regret and sorrow in life than this.

　　 Fortunately, Chen Xin is not without the opportunity to see his parents again, as long as he can traverse the thousands of miles blocked in front of him.

　　 wiped away the tears on his face, flipped through the old photos and looked at the parents on it, Chen Xin bit his lip and confirmed that he wanted to go back to his hometown to find his parents.

After tearing off a piece of paper from the notebook, writing the words “I want to go home”, and pasting a family portrait of his family on the paper, Chen Xin posted this paper in the living room most conspicuously s position.

　　 Chen Xin, who had determined his goal, looked at the parents in the photo. There was no sadness in his eyes, and some only had determination.

　　————————————————

　　 It is not an easy task to traverse a distance of 600 kilometers under the current environment, and cross four provinces to return to their hometown to pick up their parents.

Of course, it is not impossible to imagine. Although the round-trip is 1,200 kilometers, which adds up to nearly 3,000 miles, even if you drive a car before the disaster, you have to run a day and a night. Even if you take a train, it takes eight or nine hours. Traffic is completely cut off now.

　　 According to what Chen Xin heard from Qin Lan, although the national railway network and highway network have been greatly affected, the main railway lines connecting the provinces are still open.

As the north gate of Hunan Province, this city is an important land and water transportation link connecting Hunan Province and E Province. Even in this situation, there will be a train loaded with supplies coming from E Province every week. The city and the capital of Hunan Province adjacent to the city and surrounding counties and cities provide supplies.

　　 Although I don’t know the traffic conditions between Hubei and Anhui provinces, since the railways between Hunan and Hubei provinces are unobstructed, there should be a working railway line between Hubei and Anhui provinces.

　　 If Chen Xin just returned to his hometown to pick up people, without considering the system, finding a way to get on the train to E Province is his best and only choice.

　　 As for taking a car to go on a high speed…not to mention that the highway is not accessible, it is just a terrible thing to drive for more than 600 kilometers in this kind of weather of minus tens of degrees.

　　A little carelessness is a car crash.

　　 And it’s still unknown whether the car can go on this road, not to mention the black and invisible visibility outside.

　　 Even if Chen Xin wants to choose a road, he can only consider choosing a road by transforming his car into an all-terrain vehicle with the help of the system.

　　 Although the road is difficult, if Chen Xin wants to return to his hometown to pick up his parents, he really can only choose the road.

　　Under the current situation and the general environment, it is obviously impossible for the railway to have passenger transportation, and under the end of the day, it is too late for ordinary people to hide in the refuge. Who will take the train to travel far?

　　 So even if Chen Xin might get a train ticket through Qin Lan or the SWAT team, he would probably not choose to take the train, but drove the road back to his hometown.

　　 Of course, the SUV in his garage can’t be driven back. Even before the disaster, he set off from the city with a tank full of gas. He definitely had to refuel once on the road to his hometown, otherwise he couldn’t run home.

　　 And in this situation, how can there be any gas stations on the highway that can operate? You can’t say that you put oil on the road in barrels, and pour it into your mailbox when you run out of oil?

　　 In that case, in addition to filling up the car itself, Chen Xin must at least carry enough fuel to fill two tanks in the car to ensure that he can drive the car over and back.

　　 So to drive back, Chen Xin had to upgrade his car, either by increasing the fuel tank or changing to a different power.

　　 Increasing the fuel tank is a way to solve the problem. Although carrying more fuel also means that the load on the car is higher, but adding more water to the surface and adding more water to the surface is indeed a way to solve the problem.

　　 If you change to a different kind of power, it is expected that the system will be upgraded to an energy source that can be used for a long time, such as a power source such as a nuclear battery.

A nuclear battery is not something that only exists in science fiction. Its official name should be a radioisotope battery. As early as 2012, the Curiosity rover launched by the Federation installed a nuclear battery that can last for 14 years~www. mtlnovel.com~ In the aerospace field, this technology is gradually being widely used.

　　 Chen Xin felt that if he could install a nuclear battery like this in his car, it should be enough to go back to his hometown from the city and then run back.

　　 Curiosity rover weighs 3,893kg. Since nuclear batteries can drive it to run and have a service life of up to fourteen years, it is naturally not a problem to drive a car.

　　 But humans have not yet been able to really apply this stuff to cars. As for the reason… The total investment in the project of the Curiosity rover is 2.6 billion US dollars.

　　 Of course, for Chen Xin who has a system, he only cares about how many survival points he needs to consume to upgrade his car to nuclear power.

　　 Although he missed his parents very strongly, Chen Xin did not intend to leave immediately.

The conditions of his refuge are not perfect now. Taking his parents back is that there is no place to live, and the refuge is not enough to cover the consumption of three people. He must upgrade the evacuation as a whole at least once so that more refuges can live in. People can produce more food before considering bringing their parents back.

　　 Although it is more than enough to take care of his own life by himself, after taking his parents back, it will consume three people, which is three times more than Chen Xin alone.

　　 If you don’t prepare well, taking your parents back will only make your life worse and let your parents suffer along with you.

　　 So despite his firm determination to bring back his parents, Chen Xin decided to make all the preparations first, and then plan to bring back his parents.

　　 wrote these things on the paper pasted with the family portrait. Chen Xin looked at the family portrait and touched it, making him more determined to bring his parents back.
