In the next two days, Xu Yuan still did not cross over to the end of the Ming Dynasty.

Instead, they waited for the goods to arrive through the warehouses of the alliance companies.

At the same time, a new purchase order was also prepared, and Lao Zhu was responsible for the next batch of purchases.

Because at the end of the Ming Dynasty, the spring plowing work has officially begun.

In addition to Xujiazhuang, there is no need to add too many things, and the other ten newly established manors, in order to improve production efficiency and increase this year's grain production, some products of modern society must be purchased.

For example, the drought-fighting pumping machine, which is an essential artifact to ensure a good crop harvest, must be purchased at least ten per estate.

For example, excavators are used for the construction of roads and irrigation canals, the construction of houses, and the clearing of land.

For example, the ploughing planter, while ploughing, also completes the sowing work, can plough hundreds of acres a day, but also have to buy hundreds of units.

There are also improved seeds, fertilizers, and pesticides, which are indispensable.

In addition, the electric rice mill in the rice mill can quickly remove the husks and is used to process rice and wheat, which is extremely efficient, replacing the hard and inefficient work of the ancients.

A beater for grinding beans.

Mechanical press equipment for oil mills.

Wood cutting machine for furniture factories.

Can sealing machines for canneries, as well as sheet metal for raw materials.

Seamless steel pipes, processing machine tools, compound fertilizers, potassium nitrate, sugar, bicycles, motorcycles, and civilian walkie-talkies used to increase mobility are used in the military.

Finally, there is the energy aspect.

In order to drive pumps, excavators, cultivators, motorcycles and other equipment, diesel fuel is purchased in large quantities, hundreds of thousands of tons, and it may not be used for a long time.

In order to drive power-consuming equipment such as rice mills, pulpers, presses, and cutting machines, it is necessary to purchase a large number of photovoltaic power generation panels, install them on the roof of the house, and use photovoltaic power generation to solve the power supply problem of a large number of electric machinery.

With a power generation of 40 watts per square meter of photovoltaic panels, each manor has to install about 10,000 square meters of photovoltaic panels to meet the most basic production and living needs.

Ten new estates means buying 100,000 square meters.

This does not include items such as batteries, transformer equipment, power lines, etc.

In a word!

This time, Xu Yuan had to purchase a lot of materials and equipment, and it took a lot of money to spend a lot of money, and it took Xu Yuan two days just to sort out the orders and think about the number of purchases.

And this is just a preparation for spring ploughing.

When the autumn harvest arrives in a few months, when the grain is ripe in a large area, we have to start thinking about whether to buy large agricultural machinery such as combine harvesters to speed up the harvesting efficiency.

It's just that Xu Yuan has too many aspects to consider, so he can only come step by step, and first find a way to do a good job in the spring plowing work in front of him.

So here's the problem.

This is a pump, an excavator, a cultivator, a rice mill, a cutting machine, etc., and a large number of diesel and photovoltaic panels are also purchased, all of which are products of modern high-tech industrialization, is this too troublesome?

Although they can bring a hundredfold increase in production efficiency, the dependence on Xu Yuan is too high, once he stops purchasing diesel and repair parts from modern society, the manor at the end of the Ming Dynasty may immediately be paralyzed and unable to operate normally.

Why not try to tap the manpower, animal power, and natural resources at the end of the Ming Dynasty, such as the invention of cattle pulling cultivators, horse-drawn seeders, and water-powered rice mills, wind-powered cutting machines, wind-powered water lifters and other facilities, although the production efficiency has increased only a few times, more than ten times, but with the work efficiency of human muscles, opened a level of gap, and also brought a huge increase in productivity, and will not form a serious dependence on modern society.

Why not take this path of primary industrialization, but play such a high-end in the first place?

Xu Yuan did this intentionally.

It was also in the 'Crossing the Grand Alliance Exchange Group' that I got advice from the bigwigs.

Because a world in the late Ming Dynasty that does not form a serious dependence on Xu Yuan and can gradually develop by itself, there is no need to exist, after all, in the later stage, there is no difference between Xu Yuan and no Xu Yuan, so what else does Xu Yuan do?

Each manor will become independent one after another, break away from Xu Yuan's control, or be co-opted by other forces, and work hard to make wedding dresses for others.

Xu Yuan would never do this kind of stupid thing!

Like the traversers in some novels, in ancient times, steel-making, cement-burning, glass-making, soap-making, and sea salt weaving, they were very busy, and they didn't worry about technical leaks, thinking that these technologies were high-tech, and they couldn't be mastered by the heads of the ancients, so the unsuspecting end was that these technologies would spread rapidly, gradually in the hands of more powerful people, and finally bankrupt your traverser, and at most twenty or thirty years.

Xu Yuan would not be so stupid.

Because modern history tells him that even the first countries to enter industrialization will maintain their technological leadership for a maximum of 30 years; Even in a country with an extremely weak industrial base, as long as it has the population, resources, and fighting spirit, it will only be thirty or forty years to catch up with the most advanced countries.

The technology generation difference is extremely unsafe, maybe a negligence, competitors will catch up, especially the more elementary technology, as long as you know the principle, as long as you have resources, backward primitive people can catch up.

Therefore, Xu Yuan chose a high-starting point technology route.

That is, to completely skip the first industrial revolution represented by the steam engine, directly start from the internal combustion engine represented by the second industrial revolution, use the diesel fuel that can be cracked by modern chemical industry, and come up with photovoltaic power generation panels with a power generation efficiency of up to 25% in modern society, as well as a variety of mechanical equipment products that can never be manufactured by the ancients in addition to modern industry.

Among them, there is a huge technological generation gap of at least more than 100 years, and it takes a whole set of industrial systems to produce crystals, and no matter how smart the ancients are, it is impossible to crack it, and the probability of technical theft is zero.

Of course, it is not excluded that some ancients, from these modern mechanical products, got inspiration, but also imitated the principle of some water-powered cutting machines, wind-powered rice mills and other products, but these mechanical products, in front of electric cutting machines, electric rice mills, there is no competitiveness, the efficiency is several times worse, even if it is invented, it can only be eliminated, can not set off any waves.

Therefore, the scientific and technological development route with a high starting point can play a very good suppression effect and create a huge technical threshold, and it is almost impossible for the ancients to catch up.

Xu Yuan's technological leadership can be maintained for a long time.

As for low-tech products such as glass mirrors, soap, and sugar, Xu Yuan simply only imported them from modern society, and did not set up factories in ancient times to produce them.

Finally, in the late Ming world, the high starting point of the scientific and technological development route, Xu Yuan will also be adjusted accordingly according to the development and change of the situation, if the resources of the entire late Ming world are in his hands, and the rule he established is unbreakable, then in order to reduce his burden, he will also transfer the modern industrial system to the late Ming world, cultivate high-tech talents, and let the ancients also enter the modern society...... But that should be quite a distant thing, and I won't go too deep here.

Shook his head.

Xu Yuan shook off all kinds of messy thoughts in his mind.

My career is just getting started, what do you want to do so far away?

……

Day 3.

On the afternoon of May 21, through the alliance company.

In the company's warehouse, seeing this pile of materials that had been basically procured in place, Xu Yuan nodded.

"Lao Zhu, you go home from work immediately to rest, I am personally responsible for the rest of the work, and the new order has been sent to your mobile phone, I hope you can complete this batch of purchases as soon as possible, I have an urgent need."

Xu Yuan said to Zhu Yuntian in front of him.

"Okay, boss, I'll go back, I'll complete the new order as soon as possible."

After working for several days, Zhu Yuntian, who was a little tired, nodded and said.

Wait for Lao Zhu to walk out of the warehouse and drive away.

Xu Yuan locked the warehouse door, and then used his mind to manipulate it, expanding the aura, encircling the piles of materials in the warehouse, and only half an hour's effort, all these materials were transferred to the underground storage room of Xujiazhuang in the late Ming Dynasty.

Once the transfer is complete, lock the warehouse door.

Xu Yuan drove back to Villa 8 in the Shengshi Haoting Community, did not stop much, first entered the underground vault on the second floor, and then opened the time door, and stepped in, his figure finally appeared in the basement of Xujiazhuang at the end of the Ming Dynasty.
