Doomsday Bunker Upgrade

With slightly trembling fingers, he opened the album, which contained old yellow photos.

Most of these old photos are photos of Chen Xin's parents when they were young, because later, when Chen Xin was in college, the rise of digital cameras made it not popular to take photos.

Gently stroking these photos, looking at the high-spirited and splendid parents and himself who was just a child, the tears on Chen Xin's face grew even more.

Everything in the photos has long since become memories, and even the place where these photos were taken no longer exists, and it is difficult to find them.

The biggest regret and sadness in life is this.

Fortunately, it's not that Chen Xin has no chance to see his parents again, as long as he can traverse the thousands of miles in front of him.

Wiping away the tears on his face, looking at the old photos and looking at the parents above, Chen Xin bit his lip and firmly determined 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 photo of his family on the paper, Chen Xin pasted this piece of paper in the living room to be the most prominent s position.

With a firm goal, Chen Xin looked at the parents in the photo, and there was no sadness in his eyes, but only firmness.

———————————————

It is by no means an easy task to travel a distance of 600 kilometers under the current environment, and travel across four provinces to return to my hometown to pick up my parents.

Of course, it's 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 will have to run for a day and a night. Even if you take a train, it will take eight or nine hours. Traffic is now completely cut off.

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

As the northern gate of Hunan Province, this city is an important land and water transportation point connecting Hunan Province and Hubei Province. Even in this situation, there will be a train full of materials every week from the direction of Hubei Province. This city and the capital of Hunan Province adjacent to this city and surrounding counties and cities provided supplies.

Although I don't know the traffic situation between Hubei Province and Anhui Province, since the railway between Hunan Province and E Province is smooth, there should be a railway line that can be operated between Hubei Province and Anhui Province.

If Chen Xin just went back to his hometown to pick up people, without considering the system, it would be his best and only choice to find a way to catch a train to Hubei Province.

As for taking a car and taking a high-speed... Not to mention that the highway is still impassable, just driving more than 600 kilometers in this kind of weather of minus tens of degrees and then driving back is a terrible thing.

A little careless, is a car crash.

And it's unknown whether the car can make it through the road, not to mention the visibility of the black hands outside now.

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

However, although the road is difficult, if Chen Xin wants to return to his hometown smoothly to pick up his parents, I am afraid that he really can only choose the road.

In the current situation and environment, it is obviously impossible for the railway to have passenger transport, and in the end, it is too late for ordinary people to hide in the shelter, 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 most likely not choose to take the train, but to drive back to his hometown by road.

With the SUV in his garage now, of course, he can't drive it back. Even before the disaster, he set out from the city with a full tank of gas. If he wants to get to his hometown, he must refuel once, otherwise he won't be able to get home.

And now, under such circumstances, how can there be any open gas stations on the road? You can't say that you use a barrel of oil to go on the road, and you pour it into the mailbox when you run out of oil on the road?

In that case, in addition to filling up the car itself, Chen Xin must at least carry enough oil to fill two fuel 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 by changing the power.

Enlarging the fuel tank is a solution. Although carrying more oil also means that the load of the car is higher, adding more water and adding more water is indeed a solution to the problem.

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

Nuclear batteries are not something that only exists in science fiction. Its official name should be radioisotope batteries. As early as 2012, a nuclear battery that can be used for 14 years was installed on the Curiosity Mars rover launched by the Federation.

In the aerospace field, this technology is gradually being widely used.

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

The Curiosity Mars rover weighs 3,893kg. Since the nuclear battery can drive it and has a service life of up to 14 years, it is not a problem to propel a car.

However, humans have not been able to actually apply this thing to cars. As for the reason... The total investment of the Curiosity Mars rover project is 2.6 billion US dollars.

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

Although he misses his parents very strongly, Chen Xin has no intention of leaving immediately.

Now, the conditions of his shelter are not perfect. One is that he has no place to live when he brings his parents back, and the other is that the shelter is not enough for three people. People, after they can produce more food, consider bringing their parents back.

Although he is now more than enough to manage his own life alone, after bringing his parents back, it will cost three people, three times more than Chen Xin alone.

If you are not prepared, bringing your parents back will only make your life worse and let your parents suffer with you.

Therefore, despite his firm determination to bring back his parents, Chen Xin decided to do all the preparatory work first, and then proceed with the plan to bring back his parents.

After writing these things on the paper with the family portrait, Chen Xin looked at the family portrait, reached out and touched it, and strengthened his determination to bring his parents back.

Originally, I planned to post two chapters for free today, but I didn't pay attention when I posted the previous chapter, and it was sent to VIP. Now I can only make mistakes.

The outbreak occurred at night, and the tenth watch started after 12 o'clock.
