In addition to this regiment, Meng Xiang also put the air force in a separate column, although there are no planes yet, but soon there will be.

These frameworks have been developed, but they have been slow to be filled. The biggest key is that there is not enough money. After the money of 2.8 million yuan was replaced by new weapons, Meng Xiang's pockets had been emptied by half, and the new weapons were easy to use, but the cost was also much higher. Soon, though.

Not only has the hospital doubled its production line, but the production speed of the chariot factory has also increased greatly, and the output of both the fast ones has been greatly increased.

Although the tank factory did not increase the production line, the production time was cut in half. A 75mm gun takes only 7.5 hours to complete.

It won't be long before there will be arms sales again.

Coupled with the money from the recent sale of medicines, there are still more than 1.5 million in his pocket, and Meng Xiang has to plan how to spend it.

The empty finger department needs to be upgraded, it takes 500,000, and the money is not much, so let's take a break for the time being.

Upgrading the tank factory can temporarily ease the supply, and there is no hurry.

The supply of the three power plants is a bit tight, and after upgrading two of them first, after spending 200,000 yuan, each power station can produce 300,000 kilowatts. It's just that the supply of coal is tight, and 6 mining vehicles have been upgraded, which can barely solve the coal supply problem.

The mining vehicles at the sub-base must be upgraded, otherwise the supply of coal will not be available, the protection there will be very poor, and there will not be much strength to support it.

There are still quite a few buildings to be built.

For example, the refining workshop can increase the comprehensive utilization rate of minerals and the conversion rate of minerals.

For example, the next step is the oil problem. With the mechanized layout in Meng Xiang's next plan, Meng Xiang is very worried about the oil problem, a little bit in the early stage can be purchased, but not in the later stage, it is easy to be stuck by others.

Without fuel, tanks and planes can't move.

Meng Xiang checked the supply in the base, but found that the exchange price was very high, far several times higher than in reality, this was the only item he saw in the logistics equipment center that was higher than the real price.

"Why is it so high? Where did this oil come from, PetroChina or Sinopec? Citigroup now sells for less than $2 a barrel, and you start with $10 here. Why is it not in line with international standards? ”

"That's not a lot of money based on the average price of time and space." Xiaohua is now answering questions in a timely manner.

"It's fate!" Meng Xiang couldn't explain some things and Xiaohua in the later generations, so he could only sigh.

The exchanged oil is okay for emergency use, but it is not cost-effective to use too much. He remembered that there were oil well facilities in the game, which could be used to exploit oil fields. It's a pity that even if he knew that there was oil nearby, he didn't dare to mine it at this time, and it was easy to summon the devil if he did.

"It's a hassle to have no oil!" Meng Xiang sighed. It was mentioned on many forums in later generations that the Germans during World War II were short of fuel, which caused tanks and planes to lie on their stomachs and lose a lot of combat effectiveness, otherwise they could have jumped for a few more years. He said that he was also short of oil, so he made a strategic adjustment that he had to go south.

At this time, even if the base has built a large number of aircraft and tanks, if there is no fuel, it will be the same as a gun target.

It seems that I can only buy oil from Britain and the United States and other countries, but the money is not much, and if there is an extra piece of oil that costs a lot, I am afraid that it will be even tighter in the future.

"Isn't there some other way to get oil?"

He unconsciously asked Xiaohua, but Xiaohua told him a piece of exciting news: because the coal oil technology has matured, the mining plant can completely convert coal into oil. It's just that the conversion rate is a bit low, and it takes 4 tons of coal to convert into one ton of oil.

Meng Xiang calculated it, although it was more expensive than the oil in reality, it was much cheaper than the exchange from the base, and the key was that he didn't need to pay for it himself. And Xiaohua also specially reminded him that if there is an ore refining workshop, the ratio of coal-to-oil will reach 3:1, which is already very cost-effective.

In the later period, the use of oil was very large, and a little fluctuation in the price was a huge number combined, so in order to save, the refinery must also be built. In addition, in order to mine gold and silver more efficiently, a sub-base needs to be built there.

It's just that the expenditure of 400,000 yuan is a bit too high, and for the time being, we can only build one in the main base to solve the problem of oil first.

The repair shop is still in a state of shutdown, and there is no service for the time being, and the upgrade is suspended.

After the base was upgraded to the second level, a new building appeared, the radar station.

After the base was upgraded, the area under its direct jurisdiction reached a distance of 100 kilometers. But beyond this distance is still a blind spot. But radar stations can provide more information from a distance, and with radar, radio applications and control can be carried out. It is possible to provide various types of radio services to combat units, and even decipher enemy codes.

The range of the first-stage radar station can reach up to 100 km, as at the base. It may not seem far away, but if the radar station is located at the very edge of the direct area of the base, then the detection range of the base can reach 200 kilometers away. No matter how far it goes, it is limited by the level of science and technology at this time, and there is not much good way, so it can only be upgraded and improved.

But this is already much better than the simple radar surname before World War II in reality, which has the role of the base brain. For its own safety, it directly took over the control of the radar around the base, which made the radar of the base very different from the radar in reality.

In order to defend against the devil's planes, Meng Xiang specially set up a radar station near Jinan. The first is to take care of Jinan's defense, and the second is to detect the movement of the devils in the direction of the base in advance. In order to prevent the destruction of the devils, the radar station is still set up in a relatively remote place, and there is a squad of people guarding here.

With the radar station, the logistics equipment center will be able to produce all kinds of communication equipment.

Siemens spent 5 sets of military telecommunications equipment, 30 sets of military telephone exchange equipment, and 50 sets of radio stations, including accessories.

After the radar station used another 100,000 yuan, Meng Xiang ran out of money again. However, Meng Xiang has become accustomed to spending money like water.

Meng Xiang's troops were adjusted, and as the new weapons slowly arrived a week later, the last batch of old weapons was also packaged and sold to Han Fuyu. There is no need to calculate carefully, all depreciation is a mess, and the mess is another income of more than 500,000 yuan.

What I got was to upgrade the last 4 mining vehicles first, and spent another 200,000 yuan, and in the direction of Qingdao, Meng Xiang built another radar station. If the devil's plane comes from the sea, it can be detected in advance. It's still a squad of guards.

The radar station consumes a lot of electricity, and one needs 50,000 kilowatts, so it has to be upgraded again, and another 100,000 yuan goes out.

Meng Xiang has been pondering for a while, although a lot of production in the base is very cheap and convenient, but relatively speaking, it is very power-consuming. However, even with the addition of electricity, it is very cheap.

In order to cope with the increasing demand for coal, two more mining trucks had to be produced and upgraded, so that another 200,000 yuan went out.

In the blink of an eye, there were only tens of thousands left.
