PS: Three of the five more chapters today have made up the monthly pass and added the update, and as of this chapter, 540 monthly passes have been added. There is one more chapter in the early hours of the morning.

――――――

The arrival of 20 billion US dollars is just the beginning of a series of economic developments, and Cai Ruichen does not plan to spend even a cent of this money to develop the base.

Rather, it is to take out this money to contribute to a larger economic empire in the future.

His current eyes are not only at the level of tens of billions, but also at the future future technology group, and the army to be raised is not only a few hundred thousand, but most likely a scale of several million.

The development of a multi-million army from scratch, plus the construction of modern troops, will require the consumption of tens of trillions.

As for arms sales, even if all countries in the world buy arms from Future Technology Group, the annual sales of arms in the international market are tens of billions of dollars.

If you want to compare monetary gains, the most important thing in arms deals is geopolitical interests.

Now that everything is starting from scratch, there is so much that needs to be done.

At present, all development must be based on the base, supplemented by economic development, and the combination of the two is the king.

Leaving the $20 billion account behind is far from enough compared to the various investments that follow.

Open the main map of the base, and today's day's harvest can almost come to an end.

On the map of the main base's control screen, deep in the desert of southern Iraq within the base's defensive radius.

A solitary structure spreads out between several large sand dunes in the desert, and a large camouflage net covers the entire building.

Here, there is no half of a human figure in sight, this strange building, and there are no doors or windows. It looks like a factory with a strange shape.

However, under this huge desert, five hundred meters underground, a small underground space has been opened.

This underground space was naturally carved out by the construction of the tank factory, and there are several passages leading to the technology expansion station above.

It's just that the production lines in the tank factories below were all dismantled. In the spare place, an ore refining plant was built.

This is a new construction mode of Cai Ruichen's DIY, because once the chariot factory is sold, the whole space will become unstable.

So simply move those production lines out of the way, use the space of the four tank factories, and build the ore refinery directly.

In the beginning, he just tried to see if it would work, and it turned out to be.

So he immediately revised the construction plan, and the ore refinery was supposed to be built on the desert. None of them are needed now.

Subsequently, the ore extraction shaft was also built underneath, and the construction of the entire capital chain from ore extraction to recovery was completed directly underground.

Now, this construction mode is still expanding, and the ore refinery built in the wasteland world is combined.

It only takes one month for the amount of funds recovered by the base to reach 500,000 per day.

As a result, all kinds of industrial construction. It can also be used immediately after.

It's just that until now, Cai Ruichen is also distressed about the five million funds consumed to build the science and technology expansion station.

After all, for him in the early stage of development. Five million is really a lot, and when you put it in the lowest level of technology, these five million funds are enough to use for several months.

Now, his eyes are used up in the blink of an eye, and Cai Ruichen, who understands more and more that funds are easy to use, is indeed a little painful when he thinks about it.

And half a month later. It's about to officially use troops against Samarra, and the funds are still relatively tight.

At present, the daily capital income of the base, except for the production of machine stewards, the rest is used to build regular army units.

In half a month, the construction of two infantry battalions and a fire support battalion has been completed.

The next half month. This construction work will be accelerated.

At present, the base barracks can recruit 150 regular army soldiers every day, and after the recruitment of any other branch of the army has been stopped, at least 2,250 regular troops can be called up in half a month.

This is also the first infantry brigade planned by Cai Ruichen to form six infantry battalions and one fire support battalion.

It is true that even if this brigade is formed by then, it will only be a basic structure.

A temporary command structure is somewhat simple because there are other branches of the armed forces and technical units that have not yet been built.

But if it is used to command operations, there is no problem.

After all, a direct combat force of more than 3,000 people, supplemented by 2,000 mobilized soldiers under the command of Idris, is also quite good in combat effectiveness.

And this brigade, plus those 2,000 mobilized troops, the actual strength reached the scale of 5,000.

The 1st Infantry Brigade is really small compared to the forces that ISIS and the Iraqi government have invested on both sides of Samarra.

But this time, instead of dealing with the two major forces in one go, Idris is participating in the fight against the Islamic State in the name of Idris in the Iraqi government.

So the real enemy is just ISIS.

As for the Iraqi government, it would like those local armed forces to be involved with the Islamic State, and naturally it will not refuse Idris's troops.

And such a battle will not end in a short time and a half, after all, the Islamic State has nearly 100,000 troops, and it will also reinforce the battle in Samarra.

Even if the 1st Infantry Brigade participates in the battle, it will be a protracted battle, but fortunately, after a long time, the base will be stronger, and there is no fear of the increase of ISIS.

And Cai Ruichen did not think about it, and then join the war after the development of the army is more complete and stronger.

He could afford to wait anyway, but the Iraqi government forces really couldn't hold on, once Samarra was completely occupied by ISIS.

Then he will have to face the Islamic State alone, so he must support Samarra while the Iraqi government still has the ability to defend.

According to estimates, the Iraqi government forces were barely able to support it for a month, and by now the fighting has a tank company, eight MIA2 main battle tanks, which were destroyed by ISIS forces in Samarra.

At present, the Iraqi government army still has more than 200 M1A2s, but there is no more than one battalion of armored troops that can still be dispatched.

Therefore, a month's time, it is almost the same, and when the Iraqi government army is exhausted, then the Red Guard Corps will set off to turn the tide.

According to Cai Ruichen's resounding calculations, when the time comes, let the war last for two months, so that the Islamic State and the Iraqi government will not be able to hold on, and then establish the sovereignty of Samarra in a big way.

At that time, when the two sides were exhausted, who could stop Idris from taking over Samarra.

Of course, if we want to accomplish these steps, it will be quite a test for the overall planning ability of the troop commanders. (To be continued.) )
