Zhu Jianji finally asked: "The chemical group in charge of Yu Kang of the Academy of Engineering Sciences, to what extent has the research and development of the application technology for rubber development progressed, and this difficulty should not be high." ”

Hang Min said: "There are certain phased results, but the rubber made from the rubber juice taken from the rubber tree has always had problems in all aspects, and Yu Kang is adding sulfur, saltpeter powder and the like to see if it can improve the performance." ”

Zhu Jianji hummed, "The process of rubber should not be difficult, let them speed up the progress, after all, once the steam engine is available, it will involve the problem of tank tires." ”

In this day and age, tracked tanks are a little difficult.

Or use tires.

Of course, tracked tanks are also being developed, and the tires are just transitional - tires tanks, or armored vehicles, are more constrained.

Terrain can limit it.

Enemy troops can also remove the tire and make it lie on its stomach.

And if the tank is tracked, it is basically invincible.

The most important thing is to get rubber, so that the permanent bicycle factory established in partnership with Bai Gui can start production, and then harvest a wave of wealth across the country.

And since the official roads of Heiguang Road and Jingguang Road have been built, trains must be built.

The train project of the Military Research Institute of the Ministry of Industry has already been approved.

And it's been a great progress.

Unlike steel battleships, trains are one-by-one, so the power system required can be adjusted according to the power of the steam engine, and if the power of the steam engine is low, then a few carriages are missing.

Although trains run on rails, there are several bus lines that can be built in the northern city.

Steam buses can be arranged.

This one is not profitable at all.

Pure face engineering.

Foreign envoys went to Daming Gyeonggi to take a look, yo ho, there is a smoking bus system in the city, the Ming weather is really not ordinary, this face is not booming?

Hang Min said: "Yu Kang's side should be able to cooperate with the test time of the steam engine, Wei Chen estimates that it will not be long after the successful test of the steam engine, and the rubber refining process on his side should also come out, and then the tank project can be comprehensively promoted." ”

He also said: "The tank project team of the National Military Research Institute, in fact, has a large internal opinion, and many people think that it should be in place at one time, according to His Majesty's design drawings, directly design and produce tracked tanks, without the excessive tire type, so as not to waste steel, if the power of the steam engine is not enough, then continue to tackle the steam engine, and the tank project can even be delayed." ”

Zhu Jianji was silent for a while, "The crawler type is too heavy. ”

Hang Min said: "It doesn't hurt to be a little heavier, originally after the tank is equipped with a steam engine, the volume is extremely large, it really can't work, so reduce the firepower configuration, only with a firepower heavy gun and light machine gun, increase the number of tanks to make up for the lack of firepower of a single tank, such a tank, as long as we build a hundred, can also crush any army." ”

Zhu Jianji snorted and said in surprise: "Do you know the war mode of the tank cluster?" ”

This is a military theory that is ahead of its time.

Hang Min was speechless.

Am I that stupid, this thing is completely conceivable.

A single tank, even if it is invincible, in the face of a whole army, can not achieve a crushing advantage, in order to maximize the power of the tank, you have to achieve the effect of clustering from the quantity.

It's like a cavalry.

Charge in a swarm is the most lethal of the pack.

Zhu Jianji thought for a while, "Then you go down and notify the tank project department, give up the tire design, and directly engage in the tracked type, well, the tire type can also be done, but it will not be made into a tank, it will be made into a carriage style, and the carriage is open, equipped with light and heavy machine guns and rifle firing positions." ”

Firepower armored vehicles, you can still do it.

Combined with tanks, a denser network of fire can be formed.

Hang Min immediately received the order.

But he had a doubt, and asked: "Your Majesty, now to fight the South Central Peninsula, it is Mu Cong's Yunnan Soldiers and Horses, Guangxi Metropolitan Division and Jiaozhi Metropolitan Division, as well as Fujian, Guangzhou, Jiangxi, Zhejiang, and Huguang Metropolitan Divisions that support at any time, and even the Jinge Group Army will not be transferred, if the Indochina Peninsula is defeated like this, and the Jinge Group Army directly penetrates Mobei, then who will we build a tank to fight?" ”

Da Ming is already invincible in the world.

If Mobei and the Indochina Peninsula are really included in the territory, no matter how many tanks are built, there will be no opponent.

Zhu Jianji smiled, "Of course it works, our target is not only the Indochina Peninsula and Mobei, but also a very broad world, such as the Rus Principality, as well as the farther Bazhou, Ouluoba, Ouluo, Daxi, Taixi, Atlantic, Western Sea, Ouhai, God, etc., of course, these countries are all scum, what I really want is actually the Ottoman Empire in the Middle East." ”

The oil-rich areas of the Middle East must be occupied in the era of the Ming Dynasty.

Hang Min was puzzled, "Can a tank run so far?" ”

How much coal is needed.

Zhu Jianji smiled, "Don't forget that the new type of steel battleship can transport tanks, and even when the time comes, we can forcibly recruit Japanese people and build an official road that runs tens of thousands of miles!" ”

That's right, build an official road that runs through the Eurasian continent.

Costly?

Inexistent!

As long as Japan is received, Lao Tzu can squeeze out the water from Japan, and levy millions of people to build this official road, and Lao Tzu will not feel distressed no matter how many people die.

Japan...... It deserves to be squeezed like this!

As soon as this idea popped up, he couldn't suppress it, and Zhu Jianji knew that it was completely possible to fight the Middle East and Europe by relying only on the South China Sea Fleet and the subsequent East China Sea Fleet, as well as Dongfeng firearms and tanks.

But the Ming Dynasty and Europe are separated by the Siberian Plateau, and it is not easy to rule for a long time.

Therefore, the best way is for the Ming Dynasty to form a link with Europe on land.

Then the official road that runs through the Eurasian continent is very necessary.

Money is not an issue.

Daming has the big stick of Dongfeng firearms, and under the wielding of the big stick, use Daming treasure money to suck blood around the world, and how much money will be needed at that time.

Manpower is not an issue either.

The entire population of Japan and Cochin, and even Indochina, could be requisitioned.

Moreover, the Maozi in Siberia and the white-skinned pigs in Europe, as long as the Ming Dynasty crushes them, they can be requisitioned to their heart's content, and the casualties in the project are not a matter at all.

And the more they die, the better, which also consumes their potential to a certain extent, ensuring that Da Ming's will always be ahead.

In other words, I don't know if the Ukrainian girls in this era are not beautiful.

European womb?

When the time comes, Lao Tzu will call it the Daming womb!

Well...... Although it may be a toothpick stirring tank, Zhu Jianji still wants to try.

Man......

If you can do it stronger than Genghis Khan, why can't you be like Genghis Khan and sprinkle seeds all over the world?!
