They all love freedom and dislike constraints, but being a soldier means following strict rules. Jiang Ning doesn’t think the four of them can adapt. 

The idea of joining the army was proposed by Zhang Chao. He explained, “Anning, the natural disasters have continued to this day, and are becoming increasingly brutal and unpredictable. We’ve survived the sandstorms by sheer luck, but what about next time?”  

They can’t fight against natural disasters with just a few of them, so they can only choose to cling to the thigh of the country. 

Not only does the country have advanced technology and national defense, but also the strongest equipment to withstand natural disasters. By obeying the country’s commands, their chances of survival would be higher. 

As expected from a salesman, Zhang Chao’s thinking was more comprehensive than the others. 

Thinking that they all had settled down brought Jiang Ning great comfort, and she hoped everything would turn out 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 submarine group of the navy.” 

“Can you also learn to operate a submarine?” Jiang Ning pretended to be surprised. “Submarines are not easy to operate. There were only a few of them before the natural disaster in our country. How come they are now so common? 

“I checked the central hall last night, and it seems submarines can still be traded. Is that true?” 

The group exchanged glances, and Zhang Chao smiled as he explained, “This submarine is different from the usual ones; it’s specially designed to deal with possible plate collisions in the future.” 

Jiang Ning dropped her jaw in shock. “Plate collision?” 

Lu Yu and the others only heard about it after arriving at the base. Just thinking about it was terrifying; it was as if there was no chance for humanity to survive. 

However, the four of them were lucky to pass the assessment and join the military, following the country’s lead. If even the nation’s strength couldn’t withstand it, being afraid wouldn’t help. 

After thinking it through, they were less scared. 

Lu Yu comforted her, “Anning, you don’t have to worry so much. The base has been thinking about countermeasures for a long time. The reason why we can become submariners is one of the plans to fight against plate collisions.” 

Jiang Ning was worried that she couldn’t find anyone to ask, and she immediately became interested. “What plan are you going to implement? Can you tell me?” 

This was already an open secret; no one in the military was unaware of it. 

Lu Yu and others did not hide it. “The base has a port and a shipyard, and it is now working hard to produce submarines.” 

Jiang Ning frowned. “Submarines can travel in the underwater, but if a plate collision really occurs, the ocean will have severe earthquakes and tsunamis, and submarines have no way to resist 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 and other devices 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 packs 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 seemed to be thinking about something. “Since the new submarines are so powerful, why do we need to escape on land if everyone can just escape in the submarine?” 

Lu Yu explained, “A submarine can only carry 10 people, while the entire base has over 200,000 people. Not to mention the shipyard’s production capacity, just building submarines requires special rare metals.” 

It has been nine years since the end of the world, and even if the whole country were to unite, the supply would not be smooth, not to mention that a lot of materials require rare metals. 

Warships, ships, airplanes, land escape vehicles… 

The scavengers have made great contributions to the base’s current scale. For survival or rescue, they risked their lives to travel through cities and found many special materials. 

As natural disasters continued to destroy, materials became increasingly difficult to find. Not to mention that the scavengers could not find them, even the army did not gain much. 

Jiang Ning was suspicious. “Since there is a shortage of materials, why do they still sell submarines externally?” 

“Of course, it is to encourage scavengers to do everything they can to find them; otherwise, the points of scarce materials would not have soared 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?” 

A few people looked at each other, and Zhang Chao smiled and solved the mystery. “The base spent so much to successfully build a submarine; it is naturally impossible to just carry humans to escape.” 

The Fire Seed Base purpose is to ensure survival and the continuation of civilization and technology. 

To put it simply, submarines are large engines. Besides carrying humans, they also need to carry giant storage containers. 

Zhang Chao compared it to a tractor dragging a container forward. 

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

If the natural disaster is over, these civilizations will be enough for humans to recover or develop quickly. 

However, the base always prioritizes human safety. The containers will be secured to the sea along with the submarines. If an unavoidable disaster happens, the soldiers can detach the containers and escape on their own. 

The containers are made of special materials and can resist tsunamis and earthquakes. Whether it is the sea or the mulberry fields, 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 the official high-level officials have signal receivers in their hands. If the disaster is over one day, they can use the signal receivers to dig or salvage the containers and use these containers to restore human civilization. 

Jiang Ning couldn’t calm down for a long time after hearing this. 

Unexpectedly, the military would make so many preparations based on the “prophecy letter.” Perhaps this is the power of the whole country. 

At present, as the giant containers are built one after another, the products of civilization from all over the country will be delivered 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 rewards those who work hard, and they finally arrived safely. 

“Anning, what are your plans for the future with Brother Shen?” 

Jiang Ning did not hesitate. “Maybe we will be scavengers.” 

Lu Yu was stunned. “You and Brother Shen are so good at fighting, there will be no problem joining the army. If you become scavengers, not to mention the difficulty of survival, if a plate collision really happens in the future, you can only obey the arrangements of the base and choose to escape by land.”
