As a superior person, Li Shimin needs to start from more aspects when considering the problem.

Although the imperial court is now rich, the price of two sets of 50,000 guan is still unaffordable.

Of course, this is not a question of whether it can afford it, even if the imperial court can fully afford it, it will never accept this price.

What are the prices in Datang now?

A bucket of rice that is not in good condition is four dollars, and the best rice on the market is only twenty or thirty dollars a bucket.

The price of a piece of cloth has dropped to seventy yuan, and even if it is a batch of silk, it is only more than two hundred yuan.

With the development of the past few years, the salary has gradually improved, and the average is about four yuan a day.

Although there are several large workshops with official backgrounds that have raised the ceiling, it cannot be denied that as long as you can find a job to do, even if it is just a small job, you can earn two or three dollars a day.

Although all aspects are developing, it is still in short supply, and it is difficult to get a large increase in wages before supply and demand are balanced.

This also means that the imperial court must stabilize prices as much as possible, if prices suddenly skyrocket, then the order that has been established for several years will not be lost?

Li Shimin doesn't have any particularly clever means, but he just thinks that the money can be released, but it should be released evenly, just recruit people to build roads or something and give the average salary, and let the people scatter and spend, so that the impact will be smaller, or even no impact.

If the money is given directly to Li Yuanjing, people like Cheng Chuliang, if they do something in their brains, it may directly cause prices to skyrocket in some aspects.

In fact, if it weren't for the imperial court has been pressing, the prices of many things would have flown up a long time ago, and of course, this has also made another industry fly.

Black market.

Despite how hard the imperial court tried to control it, there would always be some goods that fell into the hands of the black market, which could not be bought at a reasonable price, and people who were not short of money would naturally go to the black market to buy them.

Therefore, when facing Cheng Chuliang, Li Shimin was not so polite.

It was given the same conditions as Li Yuanjing, responsible for the wages and food of some workers, giving 200 yuan of profit for each unit, providing all the materials, and then placing a single 100 sets of five-piece road repair sets and 10,000 floor ploughers and graders.

Although the number surprised Cheng Chuliang, he hadn't seen any special floor turners and flat floor machines himself, okay? How is this going on?

"How do you say you can do such a simple question?" Li Yuanjing looked at Cheng Chuliang speechlessly, and secretly said that this product has never worked in the field?

Isn't it just putting the plow on the machine? Is it hard?

Cheng Chuliang nodded subconsciously: "What's the matter?" ”

"You are the stupidest person this king has ever seen, there is no one!" Li Yuanjing felt a pain in the egg.

"Shrink this thing to ...... third," Li Yuanjing pointed to the experimental machine in front of him, and after thinking about it, he felt that the layout was not suitable.

And the size is reduced, which means that the space is reduced, and the number of occupants must also be reduced.

Besides, it doesn't make sense for this thing to be too big, first of all, the steam engine technology is not advanced enough, and the power provided is not as bad as imagined.

The bigger it is, the heavier the body, and it will consume a certain amount of power to move itself, and it will be a little difficult to plow the ground, so reducing it is the best choice.

Li Yuanjing thought about it, and still felt that it was most appropriate to operate alone.

Then, Li Yuanjing found a piece of paper and drew the general shape of the tractor on it, although it is very abstract, but let's look at it alive, after all, it is not a professional drawing, and his own drawing is to tell them a general direction, and there are people to study behind the specific layout.

"The front with small wheels is good for controlling the steering, the steam engine is placed in this position, it doesn't need to be so high, but the length is greater than the height, the coal filling port is placed here, and a small coal box is placed next to the operator, and you can add coal to it regularly." Li Yuanjing pointed to the back and said: "For the coulter, a rotating winch is added above and below, and the left and right are fixed here, and the device that can move up and down can be used to fix the coulter.

When walking normally or when you need to steer, you can lift the coulter through this winch, and use this winch to let the coulter go into the ground when you are working, the only difficulty is at the interface, the shaking amplitude is too large and easy to break, too tight and not easy to control, here you let them find a way to solve it.

The motor grader is simpler, the rest remains the same, it is also a structure that can be adjusted up and down, and a ...... is installed behind it.

"Forget it, let's show you in person!" Li Yuanjing found out that with Cheng Chuliang's IQ, it seemed that he was a little difficult to understand when he said this.

At the moment, regardless of the cold weather, I grabbed a handful of soil directly on the ground, fortunately, there were still some mounds of soil when I was conducting experiments before, and now the soil is not dry in this weather, and it will be directly formed after a little pinching.

Then Li Yuanjing found some small branches and hay on the ground and stuck them on the stick.

"This width is as wide as the body, and these branches and hay should be replaced with iron, and the top should be bent to a certain extent, and the point is to push it through, and cover everything you pass.

In addition, this roller should be able to rotate by itself, and the speed can not be slow, when the time comes, just pull an axle out of the car, this is not a problem, and finally add a layer of iron plate on it, one is to prevent injury, the other is to avoid dust, understand? ”

Cheng Chuliang nodded subconsciously: "Such a high-level ......"

"......" Li Yuanjing was speechless for a while.

There are many equipment for mechanized farming, automatic manure spreaders, automatic cultivators, automatic harvesters, so many that you can't think of it, where is this?

However, Li Yuanjing in the back doesn't plan to continue to intervene, and it's time for these people to use their brains.

Of course, these devices are not realistic at this point.

It's not that it can't be made, but the people can't bear it.

Can you think of farming, people are planting one grain at a time? Put it in the cultivator and pull the seeds directly through the slow row, which in their eyes is a complete waste of food.

Automatic harvester? When they see the food scattered on the ground, they feel distressed, enough for the family to eat for a long time.

Straw grinder?

It's funny, there is no waste growing in the field this year, these straws are all treasures, it is impossible to burn them, all of them are brought home to feed livestock, and they can be used to make beds in winter, how warm they are.

For the first time, Li Yuanjing saw that the irrigation methods of the ancients were collapsed, carrying a bucket and a specially made water scoop, and watering them one by one, and not watering much, for fear of wasting a drop of water.

Li Yuanjing felt for a moment that the wisdom of the ancients seemed to be used to develop how to save the earth's resources, and if there was not enough water, wouldn't he dig a deep well? Ten meters without water will be drilled 20 meters, 50 meters, people can't go down to use equipment, a 50-meter-deep well, put it now, even if there is a big drought for three or five years in a row, it can ensure that there is continuous water in it.
