Chapter 59 Technical Traps

Rolling bearings are generally used for rotating parts, which can greatly reduce the friction of rotation.

The use of rolling bearings on the bull-powered rollover naturally saves a lot of effort for the cattle. As a result, the hydraulic rollover that originally required four bulls to pull only needs two bulls.

The invention of the rolling bearing in his era needs to be traced back to the seventeenth century. The most important part of the rolling bearing is the steel ball, and the outer ring of the bearing is relatively simple.

But even so, Xiao Ming can't let the craftsman make high-precision rolling bearings now. His method of making steel balls is only to use the lowest-end free fall motion.

This method is to let the molten steel fall freely. In the process of falling, the molten steel will naturally form a spherical shape like water. Below the molten steel is cooling water, and the molten steel falls into it and quickly cools into steel balls.

The steel balls produced by this method have different sizes and surfaces. The next step is to grind the steel balls into spheres of the same size.

Now Xiao Ming uses this kind of bearing on the Niuli rollover, in order to make the rollover have an irreplaceable accessory, so that no one can copy it at will.

Because he is also going to sell it to the merchants who open the mine with the bull power.

In this era, the water in the mine is the most troublesome problem for the miners, and the hydraulic rollover can not only irrigate the farmland, but also pump the water from the mine.

As Pang Yukun issued a decree to send skilled craftsmen to Qingzhou to study, the news of Niuli's overturning gradually spread.

Businessmen who have always been shrewd will naturally not ignore this news. In fact, because Xiao Ming has tinkered with things one after another.

Now business people are very concerned about any troubles in Qingzhou, and they hope to seize business opportunities before others.

Of course, Xiao Ming didn't hide it, and directly asked the equipment company to roll over Niuli and place it on his field for a live demonstration.

"His Royal Highness, this waterwheel is really good. The water pumped this day can be worth the ten days before."

Naturally, the local nobles in Qingzhou were the first to learn the news. Wang Shijie and others found the waterwheel after only one day.

Moreover, this kid is very cunning, and he also brought a servant, but Xiao Ming only glanced at it and knew that this person must be the top carpenter of the Wang family.

Because it was only from the rough palm of the man and the surprised look at the waterwheel that he could see it.

"Wrong, at least twelve days." Xiao Ming said to himself that although this kind of bull-powered overturn still uses bull-force, its power is basically equivalent to a modern small electric water pump.

If the cattle are continuously replaced to work continuously, the amount of irrigation is very considerable.

Qin Mu has already returned from Chang'an, this time Wei Qing and Sun Dong are also here, and the four self-proclaimed ones are all here.

Since a large number of non-local businessmen have poured into Qingzhou, the four of them have been more attentive to Xiao Ming.

"Twelve days!" Qin Mu exclaimed, looking hard at the structure of the overturned car and making a secret note.

The same goes for Sun Dong and Wei Qing. This time the four auction houses of the Chamber of Commerce were squeezed out by Xiao Ming.

Now they all want to save as much as they can, and unlike soap, this rollover is obvious here.

Xiao Ming laughed secretly, but he didn't reveal it. He couldn't hide the overturning. Now he can only say that if someone else can make it, he can only recognize it.

If he can't make it, he can make a profit.

Using the Patent Department, he can control no one in the fief to dare to copy, but he can not control the rest of Dayu Kingdom.

The four of them looked at it for a while, chatted with Xiao Ming for a while, and went back separately.

"His Royal Highness, these four are obviously stealing their studies." Luluo said contemptuously.

Xiao Ming smiled lightly and said, "Hey, just steal it if you steal it. It's not certain whether you can learn it or not."

After he finished speaking, he turned to look at the fields along the Xiaoqing River. Lu Fei's winter conscription had ended. Of the 5,000 recruits, 3,000 stayed in Qingzhou, and the rest were assigned to other states and counties.

Lu Fei's heart was also strengthened because he got 1 million taels of silver. He still did not stop recruiting in the spring. He discussed with Lu Fei and planned to recruit another 5,000 people and control the fief's army to 13,000.

If there is enough food in Qingzhou in the coming year, it will only consider continuing to recruit.

Among the new recruits, Xiao Ming asked Lu Fei to try his best to select some fishermen's children along the coast.

Naval construction is not an overnight thing, just finding a direction in the sea is a problem.

In this era, the so-called sailing is basically a Shanghai ship that travels along the mainland, so as not to lose its way, and Xiao Ming selected this group of people specifically to cultivate a generation of people who know how to sail.

Now his plan is being realized step by step according to the plan, such as the construction of the corps. Now, on his farmland, recruits are pulling oxen to reclaim the land, and hundreds of oxen are busy pulling plows.

In other uncultivated places in Qingzhou, Lu Fei was also busy reclaiming the land with his soldiers.

In order to allow the construction corps to quickly settle the fields, this time Xiao Ming equipped the corps with the best farming tools, not to mention the sufficient farming cattle, this cattle overturned is also the first time to deliver.

He is counting on the granary of the fief to be full in the coming year.

Luluo followed Xiao Ming's gaze and said with a smile, "Your Highness, this is the first time I have seen a soldier like this."

Xiao Ming tapped Luluo on the head, "Follow this king, what more things did you see for the first time?"

After walking around the cultivated land, Xiao Ming checked the situation of the reclamation, and then went to Qingzhou City with Luluo.

At this time, there is still snow on both sides of the official road leading to Qingzhou, and the cold of winter has not yet faded away, but spring is not far away, and it will be a season full of hope.

Like his fief, it is a place of hope.

After two or three months of busy work, he tinkered with a lot of commodities that Da Yu did not have. These commodities are also expanding their influence and bringing him continuous profits.

But the road ahead was unknown, and he did not dare to relax at all.

Born in the royal family, sometimes you can't help yourself, if you don't go forward, you will be behind the abyss.

Entering Qingzhou City, the rushing businessmen from other places made Xiao Ming smile. Now he has at least taken the first step. Next, he will attract more businessmen to buy land and build workshops in Qingzhou.

Then the commodities produced from Qingzhou are continuously transported to various places in Dayu, bringing huge profits.

In order to achieve this goal, he also needs to come up with more products that attract merchants.

In Xiao Ming's eyes, perfume, soap, and liquor are just the lowest-end ones. Niuli rolls over a little bit of technology, and countless technologies in the technology library are still waiting for him to turn into actual products here.

But now Xiao Ming has realized a problem, that is, his fief is seriously lacking in technical talents, and Pang Yukun has set a very good precedent by sending craftsmen from various states and counties to study.

Now is the time to reserve technical talents to expand the scale of production, and this batch of technical talents will be born from slaves, because this is currently the easiest person to control.
