Although it cost 1 million to upgrade the science and technology center and 50,000 yuan to upgrade the hospital, plus the money he had saved before and the money he had recently sold medicine, Meng Xiang still had more than 1.4 million on hand, which was much better all of a sudden.

Upgrades, still upgrades.

The mining plant also needs to be upgraded.

The next step is to upgrade the tank factory and the logistics equipment center, which are the main sources of weapons and equipment, and naturally should be prioritized.

By the way, Meng Xiang also built the Air Force Command.

Without the Air Command, it would be impossible to develop the air force. The devil's plane is coming, and it can only be bombed passively. It's just that the requirements for the place where the air finger department needs are relatively high, because the airport is built together with the air finger department, and the airport covers a large area and needs to occupy a lot of land. However, there is no such suitable place in the core area of the main base.

There is no way, this still needs to communicate with the locals, it is not possible to force it, it can only be purchased. Fortunately, the area under the direct jurisdiction of the base has been expanded, and there are more places to choose from. In the end, he spent 100,000 oceans to buy a large piece of flat land.

In Meng Xiang's impression, there will be a military airfield here in the future. It was also tested by the base, and the most suitable place for the construction of an airfield was within the jurisdiction.

Because of the distance from the base, a company of security guards was stationed here.

All of a sudden, more than a million went out. Meng Xiang's money bag is about to be empty again.

Meng Xiang looked at the display on the big screen and wanted to cry without tears.

He himself has been counting for a long time. 100,000 for mining plant upgrades; The tank factory was upgraded to 500,000; A logistics equipment center actually needs 100,000 yuan, and other building upgrades are similar to the construction cost, but the logistics equipment center upgrade is doubled; Another empty finger department was built, and another 500,000 yuan was spent.

Coupled with the cost of production of weapons and the like, in this way, there is only a little more than 100,000 left on hand.

The huge amount of money that passed through is gone. I thought that with the huge profits of arms, it would be faster to make money, but who knew that it would be faster to spend money.

This time, plus the construction and upgrading took a lot of time, after all, the construction of robots is limited, and this time there are many buildings to upgrade.

Looking at the upgrade and the construction robot that looks like an ordinary person is busy, Meng Xiang's heart is also filled with a sense of fulfillment. My own world is being built step by step.

In a week's time, according to the money on Meng Xiang's hand, the upgrade of the upgrade was completed, and the construction of the construction was completed. Even the mining vehicle, Meng Xiang has upgraded two, if it is not for the lack of extra money, he will upgrade.

At the beginning, Meng Xiang tried to spend 50,000 yuan to upgrade a mining vehicle, but found that the surname of the armed mining vehicle upgraded to the second level could be greatly improved, and there was a earth-shaking change.

The speed of the mining truck has increased to 30 kilometers per hour, and the load capacity has increased by five times, reaching 50 tons. The problem of transportation was solved at once.

As a result of the upgrade, the power required for each building has doubled. The energy supply has not kept up.

There are abundant coal resources in the surrounding area, but it can't be mined or transported. The surname of the mining vehicle can be greatly improved, and the long coal transport vehicle can be liberated.

A fully automated armed mining vehicle can mine and transport 50 tons of coal in an hour, and the speed of running back and forth from the nearest coal mine does not exceed half an hour, and nearly 800 tons can be mined and transported in a day, and two vehicles can meet the needs of a first-class power plant.

In this way, the power plant can also be upgraded. The problem of doubling the amount of coal required to upgrade the power plant has been solved.

In addition to the coal in charge of the power plant, the 12 mining trucks can also mine some mineral resources in exchange for money.

A car specializing in mining and transporting aluminum ore can earn 16,000 yuan a day, which is also a lot of wealth.

Still, relying on the gold and silver traded is not an option. After all, the total amount of gold and silver in the world is not much, until the end of this century, gold is only 50,000 tons of inventory, silver is only more than 400,000 tons of storage, all hollowed out is not enough to upgrade the base to the highest grade.

Now the base level is low, and it can't be revealed, and it can be dealt with through gold and silver trading, but in the future, I am afraid that there will be a shortage of gold and silver. During the war, gold and silver were held in people's hands, and most of them were concentrated abroad. When the time comes, where will there be so much gold and silver available?

Or the most real exchange of minerals for money, at this time the mining of underground minerals has not yet been charged all kinds of taxes and fees, in addition to the mining vehicles consume some low-cost electricity, the total cost is lower than the production of weapons, that is, the time may be a little slower, and the mining of the descendants of the future generations, Meng Xiang, who had scolded a lot in the previous life, was a little embarrassed.

But now it is important to protect himself, Meng Xiang is not a pedantic person, so Meng Xiang thought about upgrading all the mining vehicles and building dozens more, but unfortunately the money is gone.

I can only save money and continue to sell arms.

"Why? Why do you do it again? Is this restriction or masochism? Meng Xiang once again squatted in the corner with a wronged little daughter-in-law, silently tearing and drawing circles, he no longer had the heart to argue with Zhinao, its ubiquitous rules.

But after the brain was upgraded, Xiaohua undoubtedly became a lot more surnamed, and she was still trying her best to explain it to him.

"Commander Xiaobai is no longer a first-level novice commander, and after being promoted to second-level in the center of the main base, the novice protection regulations have been canceled. A total of 22 Catch-laws have been adjusted accordingly. As soon as Meng Xiang heard the twenty-two military regulations, he figured out that he was not too wronged.

"So, let's talk about it, how to calculate the cost of the weapons produced by the base?" Meng Xiang's tone had calmed down a lot, but his mouth was still grinning.

Originally, the base was constantly upgrading and building, which was a great joy, but Meng Xiang was not happy for long, and he found that the accounts on the money were a little wrong, and when he asked Zhi Brain, he learned that there was a problem with the production of weapons that Meng Xiang relied on the most: the cost of weapons has been greatly adjusted, and the cost of some weapons has increased.

After upgrading, the level of science and technology has improved, but the cost has increased? Meng Xiang was angry and came to Xiaohua Theory again. Xiaohua's system adjustment crushed Meng Xiang's anger. It's an adjustment again, Meng Xiang heard it, and there was only a grudge left, and when the system was adjusted, he didn't reason with you at all.

"The cost of weapons is calculated differently depending on the time barrier and the level of the base. The production of a weapon at the current stage of the Space-Time Barrier requires only a quarter of the lowest cost of that weapon at that time. Half of it is the super-tech productivity level bonus of the base, and the second half is the excess consumption bonus generated by the base transportation without breaking through the time and space barriers. If it is a stage that crosses the barrier of time and space, or crosses the base level, it also has a bonus of one-half to one-third each. ……”

After Xiaohua was upgraded, it was true that the surname was changed a lot, but after saying a lot of things that still made Meng Xiang dizzy, he could only ask for example: "How much does it cost me to produce the Mauser G98 rifle, according to your formula, give me a list." ”

"Now the international average cost is 18 US dollars, one-half of the base super technology productivity bonus, one-half of the saving transportation consumption bonus, because the Mauser G98 rifle can be produced in the first World War base, and the cross-base level is added to one-third, so the base production cost of the Mauser G98 rifle is 1.5 US dollars, and the Chinese silver dollar is 4.6 yuan according to the average price comparison of the time."

It's a lot lower than the original price, so some weapons cost less.

Meng Xiang patiently asked the others, and finally after Xiaohua answered them one by one, he finally understood one thing:

After getting rid of the newbie protection, there are good and bad.

(Today, I will continue to watch three more, and I have not yet left the novice area, and newcomers urgently need to recommend and collect)
