Doomsday Bunker Upgrade

Although Li Yulong brought Chen Xin a fruit and vegetable machine, it was not that kind of large-scale dryer after all, and Chen Xin still needed to slowly bake the rice he picked one by one.

Fortunately, this machine can bake 20 trays of millet at a time, with a processing capacity of 30 to 40 kilograms. One bag of millet can be dried in two times, and three bags of millet are only six times.

From time to time, he stretched his hand in and turned it over. In addition to turning up the millet with moisture at the bottom, Chen Xin was also feeling the dryness of the rice with his hand.

Only after confirming that the rice grains are completely dry and feel no moisture at all can they be bagged for storage.

After drying more than 200 catties of rice, and then pounding off the bran, about 170 catties of rice can be produced. Based on the amount of food Chen Xin eats, he can eat it for half a year.

As long as he can harvest twice a year, it is enough to ensure his ration. In the greenhouse, because he does not need to consider the relationship between environmental temperature and humidity changes, he can calculate according to the most suitable conditions, with a cycle of 90-110 days. , three seasons per year.

In this way, Chen Xin can obtain more than 600 catties, nearly 700 catties of rice, more than 500 catties of rice, and more than 100 catties of bran in a year.

Coupled with the fact that he can harvest hundreds of catties of vegetables every month in his greenhouse, so much food is enough to feed two or three people.

"As long as the old farmer sends the fish again, and gets new seeds through Xiaolong and Alan... I can finally eat and drink without worrying about it." Chen Xin briefly calculated the output of his greenhouse, and finally had a feeling in his heart. A solid feeling.

When you have food in your hands, don't panic. This old saying to describe the people of the Yan Kingdom is especially true no matter when you put it.

After counting the resources in his hands and making sure that he could ensure the rations for the three people, Chen Xin finally put on the agenda to return to his hometown to pick up his parents.

The reason why he didn't think about taking action before was because Chen Xin understood that if he couldn't guarantee enough food supply, it would be useless to bring his parents back.

Now that the food supply can be guaranteed, the prerequisites for bringing back my parents are ready for formal consideration.

To pick up his parents, Chen Xin had to cross a distance of more than 600 kilometers for four high-ranking officials.

In the past, it was possible to travel at high speed without stopping, and it would take more than half a day to complete the journey. Now, in this environment where everything is frozen and the snow on the ground is almost one meter deep, it is not easy to cross such a long road. thing.

Therefore, the first thing Chen Xin needs is a car that can cope with the current environment, and can run the whole distance and then go back and forth.

Of course, there are such vehicles, generally known as all-terrain vehicles, which are capable of maneuvering in a variety of complex terrains and special conditions including jungles, mountains, deserts, snow, beaches, swamps, water networks and lakes.

Among the various types of all-terrain vehicles, like Li Yulong's remodeled luxury RV, of course, it is also an all-terrain vehicle, but compared to his luxury RV, Chen Xin is more inclined to be equipped with the military of the Yan Kingdom." The two types of all-terrain vehicles are the "Reckless" and "Horse".

Both "Meng" and "Shored Horse" are articulated hatchback tracked all-terrain vehicles, in addition to the cockpit, a carriage can be towed behind.

Among them, the Mang-type all-terrain vehicle is a heavy-duty vehicle, with a self-weight of 30 tons and a load of 30 tons. It is a very powerful and reliable large-scale transport vehicle.

The horse is slightly smaller, with a weight of about ten tons, a maximum speed of 60 kilometers per hour, and a maximum driving distance of 500 kilometers. It can easily cross a 1.5-meter-wide ditch with its tracks, and it can also climb over a 0.6-meter vertical obstacle. , climb up slopes above 30°.

Compared with Chen Xin's own SUV, the gap between the two is like the difference between an elephant and a horse.

According to Chen Xin's vision, getting a horse and then transforming the rear compartment into a RV-style living compartment is enough to meet the needs of his journey.

Of course, it would be better if there was a Mang-style. After all, the Mang-style's larger and heavier body also means that it can have a larger carriage, carry more supplies, and have a larger living space.

It's a pity that Chen Xin didn't think of this matter before the disaster, otherwise, the horse can still think of a way.

But now, he can still transform into an all-terrain vehicle by upgrading his SUV.

And to be honest, as the snow gets deeper and deeper, Chen Xin's SUV is indeed becoming more and more incompetent for travel needs.

Without the one-meter-high tires of Li Yulong's converted RV, driving on this nearly meter-thick snow, if you are not careful, the wheels will sink into the snow.

So after thinking about it, Chen Xin's first thought was to change the tires of his car into tracks.

If you compare speed, of course the tire wins, but if you compare capacity, the difference between tire and track is as big as the difference between them in speed.

If the track is changed, the engine will also need to be modified. After all, the load of the track is greater than that of the tire, which requires the engine to have a stronger output power.

In this case, a high-horsepower diesel engine is indeed more suitable than a gasoline engine.

However, for the power system of this car, if it is to be transformed, Chen Xin is more inclined to electric drive rather than fuel power.

First of all, electric drives are cleaner and more efficient, and electric vehicles are no longer a new thing. Except for the two problems of battery and charging that still restrict the use of electric vehicles, this new form of vehicles has long been accepted and recognized as the future. Trends in automotive development.

For Chen Xin, there are no factors that restrict the amount of electric vehicles. The isotope thermoelectric battery as the power source and the high-performance energy storage battery as the battery pack are enough to make an electric vehicle run for decades without stopping. .

For others, this is still an unattainable idea in the laboratory, but for Chen Xin, it is a matter of smashing the survival point and upgrading.

And he is seriously preparing to do so, intending to upgrade his car after completing the overall upgrade of the shelter.

While considering the power system and the way of travel, Chen Xin is also thinking about how to design the living compartment of this car. Is it a hatchback like the Mang-style and the horse? Or is it the same one as Li Yulong's car?

Both of them have their own advantages, but they also have their own problems. Chen Xin rubbed his lips and whiskers and fell into thinking.
