Walking in the barracks near dusk, Cai Ruichen's originally angry mood was eased a lot because of the greetings of the townspeople.

In the barracks outside Marin Town, hundreds of mobilized soldiers are training inside.

Covering an area of 640,000 square meters (0.64 square kilometers), the barracks is surrounded by four walls and has a side length of 800 meters, which is considered a large camp.

In addition to the inability to take off and land fighters, it can already meet the take-off and landing and maintenance of a small number of helicopters.

In the corner of the barracks, there is a helicopter take-off and landing point, and two hangars, but there are no helicopters here.

And in the huge barracks, there is also a small garage where various vehicles of the scale of a reinforced battalion can be parked, as well as a garage for maintenance.

Engineers can repair armored vehicles and even tanks here.

Each barracks can barely be squeezed into a regiment of troops, and normally speaking, the size of a reinforced battalion can be accommodated, and the reasonable arrangement is about 1,000 troops.

After all, there are various training grounds in the barracks, both indoor and outdoor, as well as a shooting range, various cross-country obstacles and playgrounds.

There are various facilities such as a fighting hall, gymnasium, library, and computer room, as well as barracks, restaurants, and ammunition depots, so it seems that the barracks are very large, but the layout is actually very compact.

After all, this is not a new barracks, the soldiers in it are ready to participate in the battle at any time, once all kinds of equipment are complete in the future, the barracks is the best troop assembly point.

However, Cai Ruichen has always felt that a barracks is too small, and there is no field training ground around, and the proposed training ground is simply not suitable for large-scale training of troops.

However, it can barely be used now, and when there is a chance and time in the future, Cai Ruichen will also build the barracks together, and then connect them and use several barracks to form a more camp.

If necessary, it will be possible to accommodate a brigade or even a division-sized unit.

Of course, the real role of the barracks is not to accommodate soldiers, but to recruit soldiers.

There is real currency, and in Iraq, it doesn't matter how big a barracks you want, even if it's an airport, after all, engineers know everything.

But there's one thing that can't be replaced, and that's the base soldier's enlistment system, which the engineers can't build.

And every time a barracks is built, the real value lies in the soldier recruitment system in the barracks, and other facilities such as facilities are nothing compared to this system.

It's just that compared to the cost of manual construction, 600 funds for a barracks of this scale is simply a free gift.

Therefore, Cai Ruichen never planned to use artificial expansion of the actual scale of the barracks, not that there is no way to expand, but there is no need to spend those unjust money.

Moreover, there are not many troops now, and there is no need for him to expand the area on the basis of this barracks.

It's just next door to this barracks that the engineers are building an empty shell of the second barracks, and when the second barracks in real space of the base is completed, the wall between the two barracks will be torn down to form a large barracks.

The area will also be the sum of the two barracks, and the architectural layout of the two barracks will have to be modified, to the least.

This is the need for development, since taking the wasteland world of Shaxi Town, Cai Ruichen has also begun to focus on the real space temporarily, and the scale of the army will be further expanded.

Two barracks are not even enough, three or even four barracks are needed, and it is possible to meet the demand.

The combined area of the four barracks is almost a quarter of the size of Marin Town.

However, with the shells of various factories, all of them were built rapidly, and the area of the town was rapidly expanding.

To this end, Cai Ruichen has also made a development plan, if the future development is smooth, the town of Marin, which has a vast flat land around it, and is close to enough fresh water sources, will become a big city in the future.

Now the development of Marin Town, everything will be inclined towards industry, and when the population becomes more and more in the future, industry will be transferred outward.

As for the Red Alert weapon production unit, Cai Ruichen will make other arrangements, and from noon, he will start to build a wall under the town.

That's right, to build an underground wall at ten times the cost.

Now, a section of the wall has been completed, and according to Cai Ruichen's plan, the first underground wall will enclose the town of Marin in a five-kilometer area in the center.

As long as this wall is built, if he wants to, this wall will rise from the ground and completely protect the town of Marin.

Although for modern military warfare, the wall is not very useful at all, but it does not mean that it is useless at all, at least in Cai Ruichen's opinion, this kind of wall that can be concealed at any time is quite easy to use.

Just the circumference of a circle with a radius of five kilometers has reached 31.4 kilometers, and the wall built underground costs 5,000 dollars for every 100 meters long.

The circular perimeter of 31,400 meters is all to be surrounded by walls, and the walls will have to be built 314 times, and the funds consumed will reach 1.57 million.

Although the construction of defensive structures does not conflict with construction units and other non-defensive structures, the construction of the wall on 314 times will take about a week.

Fortunately, Rome is not something that can be built in a day, and the capital of more than one million is also a huge number for Cai Ruichen now.

Therefore, it is impossible for him to keep building, otherwise once the inventory in the Wasteland World's refined iron warehouse is exhausted, he will face the dilemma of insufficient funds.

Cai Ruichen's plan is to slowly build it within two months, and then develop the industry according to the situation, launch commodities, and after making a certain profit, build an ore refining plant in the real space, and find a way to buy ore to recycle.

But it is not easy to complete such a layout, and even in Cai Ruichen's plan, it will take at least one or two years or even longer to achieve it.

Therefore, for the current development, it is better to be down-to-earth, and the reason why he spent so much money to build a 31-kilometer-long underground fence.

It is mainly to prepare for the construction of underground industrial clusters in the future, many construction units can be built underground, and there is no need to worry about exposure of construction units built underground.

The plan is also to rationalize the development and pave the way, otherwise many inexplicable things will be too dazzling as soon as they appear.

With a radius of five kilometers, it covers an area of 78 square kilometers, which can fully meet the development of several years.

Now, Cai Ruichen's eyes have seen the next two or three years, and many plans are even scheduled for five years.

Taking a long-term strategic vision and developing from the ground up is the right thing for a qualified leader to do.

As for base funding, it will be a constant concern for the next few years.
