They all love freedom and don't like restrictions, but real soldiers are very strict in all aspects. Jiang Ning doesn't think the four of them can adapt.

The idea of ​​joining the army was proposed by Zhang Chao. He explained: "Aning, natural disasters continue to this day, and they are getting more cruel and unpredictable. We are lucky to survive the sandstorm, but what about the next time?"

They can't fight against natural disasters with just a few of them, so they can only choose to rely on the country.

There are not only technology and national defense here, but also a lot of strong equipment to resist natural disasters. If they obey the country and follow the command, their chances of survival will be higher.

As expected of a salesman, he wants to be more comprehensive than others.

Thinking that they all have a place to go, Jiang Ning is very relieved from the bottom of his heart, and hopes that they can all be well.

She asked curiously, "Are you divided into different branches when you join the army?"

"Yes, the base is divided into the Army and the Navy, and we belong to the Navy's submarine group."

"You can also learn to drive a submarine?" Jiang Ning pretended to be surprised. "Submarines are not easy to make. There were only a handful of them in our country before the natural disaster. How come they are now so common?

I took a look at the central hall last night. It seems that submarines can be traded abroad. Is this true or false?"

Several people looked at each other, and Zhang Chao smiled and explained: "This submarine is not that submarine. It is specially designed to deal with the plate collision that may occur in the future."

Jiang Ning dropped his jaw in shock. "Plate collision?"

Lu Yu and others only heard about it when they arrived at the base. Just thinking about it makes people shudder. It is simply not giving humans a way to survive.

However, the four people were lucky enough to pass the assessment and join the army. Everything follows the country. If they can't even resist the power of the country, it's useless for them to be afraid.

After thinking it through, he was not so scared anymore.

Lu Yu comforted him, "Aning, you don't have to worry so much. The base has been thinking of countermeasures for a long time. The reason why we can become submariners is one of the plans to resist plate collision."

Just when he was worried about not being able to find anyone to ask, Jiang Ning suddenly became interested, "What plan are you going to implement? Can you tell me?"

This is already an open secret, and everyone in the army knows it.

Lu Yu and others did not hide anything. "The base has a port and a shipyard, and we are now increasing the horsepower to produce submarines."

Jiang Ning frowned, "Submarines can travel through the underwater world, but if there is a real plate collision, the ocean will experience severe earthquakes and tsunamis, and submarines have no way to withstand it."

Once the parts are damaged, it will still endanger lives.

However, Lu Yu is very confident, "They are not only submarines, but also hibernation cabins..."

This is a new type of submarine. When encountering an irresistible marine disaster, the engine device and other parts can be retracted into the cabin, and the submarine will drift with the current.

The inner cabin has a shock-absorbing design, and the oxygen bags and food can be supplied for half a year. The outer shell material is extremely hard, and it will not be damaged even if it hits a reef or is attacked by marine life.

Jiang Ning thought, "Since the new submarine is so powerful, why do we need to escape on land?"

Lu Yu explained, "A submarine can only carry 10 people, and the entire base has more than 200,000 people. Not to mention the production capacity of the shipyard, special rare metals are needed just to build submarines."

It has been nine years since the end of the world, and even if the whole country is combined, it is still impossible to supply smoothly, not to mention that there are many materials that use rare metals.

Warships, ships, airplanes, land escape vehicles...

The scavengers have made great contributions to the scale of the base today. For survival or rescue, they travel through cities at great risk and find many special materials.

As natural disasters continued to cause damage, materials became increasingly difficult to find. Not only could scavengers not find them, but even the military did not gain much.

Jiang Ning was suspicious, "Since there is a shortage of materials, why do you still sell submarines to the outside world?"

"Of course, it is to encourage scavengers to find them by all means, otherwise the points of scarce materials would not soar so much."

But Jiang Ning always felt that something was wrong, "Building a submarine consumes a lot of materials and labor, but in the end it can only carry 10 people to escape. Isn't it a waste?"

After a few glances at each other, Zhang Chao smiled and solved the mystery, "The base cost so much to successfully build a submarine, it is naturally impossible to just carry humans to escape."

The Spark Base, everything is done for inheritance.

In addition to the inheritance of life, there is naturally civilization and technology.

Let's put it this way. A submarine is a big engine. In addition to human escape, it also needs to carry giant storage boxes.

Zhang Chao compared it to a tractor, "It's like a tractor, dragging containers forward."

The containers may contain books, antique calligraphy and paintings, seeds and grains, clothes and leather, medical equipment, precision machinery, etc., collectively referred to as human civilization products.

If the natural disaster ends, these civilizations are enough for humans to recover or develop quickly.

It's just that the base always puts humans first. The containers will be riveted to the sea with the submarine. If an irresistible disaster occurs, the soldiers can consider disconnecting the riveting and escaping on their own.

The container is made of special materials and can withstand tsunamis and earthquakes. Whether it is a vast sea or a mulberry field, the device design inside can ensure that the items will not be destroyed within 20 years, and at the same time, it will continuously send out signals.

The military or official high-level officials have signal receivers in their hands. If a disaster is over one day, they can use the signal receivers to dig or salvage containers and use these containers to restore human civilization.

Jiang Ning was unable to calm down for a long time after hearing this.

Unexpectedly, the military would make so many preparations based on the "prophetic letter". Perhaps this is the power of the country.

At present, as the giant containers are built one after another, the civilized products from all over the country will be sent to the military base in South China.

As far as Zhang Chao and others know, there are 3,000 containers alone, and each of them is about 400 cubic meters.

For ordinary people, this data is already amazing enough, but it is a drop in the bucket for the country's civilized products.

They can only do so much for future generations.

In the two months since entering the military base, Zhang Chao and others would inquire about the news every two days, hoping that Jiang Ning and Huo Yishen would show up.

God will not let down those who work hard, and they finally arrived safely.

"Aning, what are your plans for the future with Brother Shen?"

Jiang Ning did not hesitate, "Maybe you will be scavengers."

Lu Yu was surprised. "You and Brother Shen are so good at fighting, so there is absolutely no problem for you to join the army. If you become scavengers, not to mention that it will be difficult to survive, if a plate collision really occurs in the future, you can only obey the base's arrangements and choose to escape by land."
