Rocky, who had made a lot of money from the sale of his armor, could not let this huge amount of money rust in the vault, and he immediately used all the gold coins.

Everyone understands that it is difficult to make money and easy to spend, especially in Rocky, who now has two sky cities and a land base under his rule, and not only is there a lot of places to spend money, but it is like a bottomless pit without a head.

For example, Thunder Eagle City, now Thunder Eagle City is undergoing urban upgrades, although Rocky has allocated tens of millions of gold coins for this big project before, but in fact, this is already a few months ago, and in a few months, tens of millions of gold coins have already been spent.

It is undeniable that this kind of spending money is simply too fast, but it is also a reasonable thing, think about it, the price of a large super crystal is close to 10 million gold coins, expanding the city, expanding the airport, building a new airport, rebuilding the research institute, this kind of everything is also a big project, so tens of millions of gold coins are really spent after speaking.

Fortunately, Rocky had expected this, he had already known that it would cost a lot of money before the upgrade, and he was ready to fight a protracted battle, and now thanks to the booming sales of the armor, he directly invested his general income in urban upgrades.

Although these investments are not as huge as they were at the beginning, not reaching the scale of tens of millions of gold coins, they are expensive in the long run, at least until the war begins, the sales of tank armors and thunder eagle armors can remain hot, so Rocky can continue to invest a lot of gold coins in city upgrades, and once the war really breaks out, Rocky believes that the sales of armors will be even more popular, so the situation can still be maintained until the city is really upgraded.

Of course, Rocky doesn't invest in city upgrades, he only uses his general income to upgrade cities, and the other general income is used to strengthen his troops.

Just like the other city lords in the sky, while the three major local forces were targeting him, he also had to be fully prepared for the third counteroffensive war, so in addition to waiting for the Apple Tree Chamber of Commerce to send more rune warships, he also began to gradually expand his armor troops.

Don't look at the fact that there are two arsenals in Thunder Eagle City now, but since the first arsenal was completed, he hasn't made too many armors for himself, except for the original attempt to break through the blockade of Heavenly Fury City, he hardly let the arsenal work for himself, and basically used it to produce orders.

And now, there are already two arsenals in Thunderhawk City, and the output has more than doubled compared to before, which finally gives Rocky some opportunities to 'profit' for himself, so when he completes some large orders, he temporarily hands over the task of completing the orders to one of the arsenals, and the other arsenal begins to mass-produce tank-type armor for Beishan Village.

According to Rocky's judgment, once the counteroffensive war breaks out, the peace of the world will be completely over, and the enraged demons will inevitably fight back wildly, and the most important target of their counterattack will naturally be the industries and bases on the land.

So Rocky must strengthen the defense capability of Beishan Village, the current Beishan Village seems to be actually very strong, but this is only the current standard, if this standard is raised a little, you will find that the defense of Beishan Village is still very fragile.

Lodge once asked Aniye and Athena about the scenes of the first two counteroffensive wars, according to Aniye, once the war broke out, the number of demons would increase exponentially, and now the number of demons harassing Beishan Village may only be a few hundred, and some more are only a few thousand, but once it is a time of war, the number of demons faced by Beishan Village will often be thousands, or even tens of thousands of demons.

In the face of so many demons, the current strength of Yibei Mountain Village is simply unable to hold it, and it is necessary to increase the investment in defensive forces, and the most important thing is naturally the tank armor.

Since the first version of the tank armor was designed, it has been several years since the development has been developed, and after three generations of changes, it can be said that the tank armor has been a very mature and practical armor, and it is the best choice to invest this mature armor in the defense of the mountain village, and the manufacturing cost of the tank armor is not high, and the training of the driver is much easier than the traditional air demon warrior, which can be said to be the most suitable choice.

In addition to mass-producing tank armors, Rocky is also producing another big killer, which is the Mobile Fortress!

It is no exaggeration to say that if it wasn't for the fact that the kingdoms didn't survive to the end, so that the research institute of Cassin City could not have the resources to build the mobile fortress completely, then it is really hard to say whether Cassin City could be attacked by demons!

Because the combat power of the mobile fortress is too strong, its steel body, as well as its incomparably strong attack power, is simply a demon's nightmare, and don't forget that after getting the mobile fortress, the research team of Thunder Eagle City modernized this behemoth, so that the combat effectiveness of the mobile fortress has become even stronger, and now it has become an insurmountable barrier in the defense network of Beishan Village, not to mention hundreds of demons, even if thousands of demons appear together, don't think about crossing the fortress half a step.

And for this kind of big killer Rocky, it is naturally impossible to forget, so he plans to use this last bit of time before the outbreak of the Great War to build another mobile fortress.

This matter is not difficult for Rocky technically, because not only does he have all the research materials for the development of the mobile fortress, but the R&D team has taken the opportunity of transformation to understand the top and bottom of the mobile fortress, inside and out, so there is no difficulty in manufacturing.

The only difficulty is production, the mobile fortress is not a tank armor, this behemoth is impossible to produce with a factory, because there is no factory in the world today that can produce a mobile fortress, so Rocky can only send another one, for this he deliberately found Orton, who is fully promoting the armed plan of Thunderhawk City, and Orton is worthy of being a master, and he immediately thought of a way with his experience in leading various large projects and big projects, that is, assembly.

Thunder Eagle City now has its own arsenal, so it can produce some of the parts needed for the mobile fortress as much as it can, and as for those parts that Thunder Eagle City can't produce, you can buy them from the outside, so that as long as you buy all the parts needed for the mobile fortress, you can assemble them in Beishan Village.

I have to say that Orton is really spicy for Jiang Lao, and one solution solves a big problem, and Rocky naturally immediately found this way to implement it, and began to order a large number of parts needed to move the fortress from the outside.

Of course, this kind of thing is not as simple as words, it still needs money, and a lot of money, but fortunately Rocky has money now. 2k reading web
