"Have you thought about it? If you think about it, ask a professional to plan the construction of your city for you, in the same way, if you want to show your achievements to your imperial grandfather, it is not enough to rely on a few books, he wants to build a military fortress here, and when he wants to establish an invincible martial arts in the north, this Beiping city will become his last guarantee! ”

Li Hang estimated that this Emperor Yingwu wanted to destroy the Turks in his lifetime.

Li Hang was more concerned about whether this Emperor Win Wu could go north directly to the North Pole by destroying the Turks.

If you can occupy a large amount of territory in the north, then it is called cool.

It must not be forgotten that Russia will be an exporter of resources in later generations, which means that it is quite rich in resources.

If you can occupy that place, it is estimated that you can directly occupy those rich resources.

With the invention of cotton and ondol, coupled with the excavation of coal, if it is possible to develop shipping, at least the coastal shipping can be replenished.

This allows direct control along the coast.

Expanding the territory, how many ancient emperors could resist such a temptation?

Absolutely nothing!

Ying Yun is also thorough at one point, and he understands the key point at once. "You said that the imperial grandfather wants to solve the Turks?"

"Almost, it's not killed or disabled anyway! It's just that you won't fight pregnancy, "As long as the compensation operation is good this time, it is possible to completely cultivate the military strength of the Great Win Dynasty."

At that time, no matter how many years the armistice agreement is, the Turks will only have a chance to breathe.

When the time comes, as long as the things are in hand, the Turks can be destroyed.

"By the way, our workshop has already taken out a prototype of this water wheel, you can take a look!"

Li Hang said and showed Ying Yun the way.

The workshop is still not a secret to this imperial grandson, but it is to open some of the outside to him, and as for some of the innermost rooms, they are almost completely closed.

This is Li Hang's dedicated workshop, although there are not many things in it, but the setting alone is enough to dazzle.

All the oil lamps were surrounded by water, and they were protected from any possible fires, not to mention, and even the contents were stored according to the categories.

Not to mention the anti-theft measures that are close to the level of perversion ♂.

Not to mention the heavy iron door, there is a lock on the outside, and a simple combination lock inside.

If you don't push things to the corresponding position, you can't unlock them.

This is also what these craftsmen came up with.

And now Li Hang showed them the bamboo human-powered waterwheel made by his own group of craftsmen!

The whole rickshaw is made of bamboo, mainly to save man-hours, after all, compared to the wood to hollow out the center, the hollow bamboo is undoubtedly the best material, and the bamboo is not easy to deform and crack due to long-term soaking.

It's even better.

"Although this kind of car is difficult to step on, it is much more convenient to lift water in efficiency than those who use buckets to carry water, especially in some dangerous places that cannot go down, only need to hang down one or two people, and these things can be installed, mainly after this kind of thing is installed, the water in these places can not worry, and after the construction of this kind of waterwheel, it can also build a hydraulic mill, so that you can also use water to grind millet, and even to hull rice."

In fact, many of these things are done by manpower, for example, the founding ancestor has the kind of thing that is used to threw with his feet, a simple wooden structure, a simple shape, and the use of the lever principle.

These things are very simple and practical.

Li Hang also made it together.

Anyway, when the time comes, these prototypes will be placed directly in an empty house, and whoever needs them will use them.

As for the value of this kind of thing, it mainly lies in its promotion value, not its use value in its own place.

Once it is popularized, this kind of thing can be put into the utensils category of that agricultural and mulberry book.

And this kind of thing can also be used to teach your own students.

Seeing that the waterwheel had been made, Ying Yun was also a little impatient. "Can I try it?"

"Yes! I'm going to get those kids moving in a minute, so let's give it a try and get it all installed! Let's give it a try! ”

These waterwheels or something, the main focus is to make simple installation, simple maintenance.

Even people who can do some simple carpentry work can easily repair it, and that's the way to go!

"You let these kids pretend?" Ying Yun was a little dumbfounded.

Can't you take such an important thing seriously?

Li Hang shook his head, looking like he took it for granted. "This matter will be delegated to those rural areas in the future. The illiterate farmers, and the artisans who don't have much experience, so we need some tests to get these kids and these illiterate people to assemble! ”

The method adopted by Li Hang is actually very simple, that is, according to the way he made his own Gundam figure in his previous life, mark the number on each installed interface, and draw an arrow on this to mark the splicing of two identical interfaces.

In this way, even illiterate people can also be spliced as long as they find the same number, anyway, as long as the production is standard, all the interfaces and sizes are the same flowers, there will be no installation problems.

As for the production of such a waterwheel.

Li Hang didn't care too much, according to the current standard, anyway, the weights and measures are there, and all he wants is to improve the level of quality inspection.

At least you don't need to polish it repeatedly after someone gets it in your hands.

Once all these quality controls are in place, this is easy to do.

A dozen children dragged the things outside, and that's where the prairie raiders were burned in the first place.

Li Hang asked them to start splicing these rice machines according to these number marks.

These things are relatively simple, and the installation is relatively simple, and you only need to tell them to install it according to the same symbols.

You don't even need to tell them what the symbol means. As long as they follow the symbol, and a piece of paper is attached to tell them how to put it together, it is estimated that they will soon learn how to put it together.

As for the meaning of this symbol, when the time comes, they will slowly become curious and learn by themselves.

And after Ying Yun saw the things drawn on those few pieces of paper, the whole person felt bad.

"Oh my God! Li Hang, do you really paint these things for those clay legs? Are you really going to teach them how to use it? ”

Teaching those peasants and lowly people, if he hadn't seen it with his own eyes, he would even think that Li Hang was crazy.
