Iron Dynasty

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

　　Using the rolling bearing on the bull-powered rollover can naturally save the cattle a lot of effort. As a result, the hydraulic rollover that originally required four bulls would only need two bulls.

　　The invention of the rolling bearing in his time needs to be traced back to the 17th century. The most important component of this rolling bearing is the steel ball, and the outer ring of the bearing is relatively simple.

　　 But even so, Xiao Ming is still unable to make artisans produce high-precision rolling bearings. His method of manufacturing steel **** is only the lowest 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 will quickly cool down into steel **** when falling into it.

　　The steel **** produced by this method have different sizes and different surfaces. The next step is the processing of the grinder, and try to grind the steel **** into spheres of the same size.

　　 Now Xiao Ming uses this kind of bearing on the Niu Li rollover, so that the rollover has an irreplaceable accessory. In this way, no one can copy it at will.

　　Because he is still going to sell it to the merchants who open the mines with Niu Li.

　　In this era, the water in the mine is the most troublesome problem for the miners, and the hydraulic dump truck can not only irrigate the cultivated land, but also extract the water from the mine.

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

　　 The always shrewd businessman would naturally not ignore this news, in fact, because of the things that Xiao Ming had invented one after another.

　　 Now businessmen are very concerned about any disturbances in Qingzhou, hoping to seize business opportunities before others.

　　 Of course, Xiao Ming didn't hide it, and directly asked the Equipment Department to roll over Niu Li and place it on the side of his field.

　　 "Your Highness, this waterwheel is really good. The water pumped this day is worth the previous ten days."

　　 The first to learn the news was naturally the local wealthy family in Qingzhou. Wang Shijie and others found the waterwheel within a day.

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

　　Because it was only since then that the person's rough palms and the look of surprise at the waterwheel could be seen.

　　 "Wrong, at least twelve days." Xiao Ming believes that although this bull-power rollover still uses bull-power, its capacity is basically equivalent to that of a modern small electric pump.

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

　　 Qin Mu has returned from Chang'an, this time Wei Qing and Sun Dong have also arrived, and all four self-appointed ones have arrived.

　　 Since Qingzhou flooded into a large number of foreign businessmen, the four of them have been more attentive to Xiao Ming, and now they are like a **** all day.

　　 "Twelve days!" Qin Mu exclaimed, looking hard at the structure of the overturned car and secretly noted it.

　　Sun Dong and Wei Qing are the same. This time Xiao Ming squeezed a lot of oil and water out of the four auction houses of the Chamber of Commerce.

　　 Now they all want to save, and it's different from soap. This is the flippant.

　　 Xiao Ming smiled secretly and didn't reveal it. He couldn't hide the fact that the car rolled over. Now he can only say that if someone else can make it, he can only recognize it.

　　 If he can't make it, he will be profitable.

　　Using the Patent Department, he can control that no one in the fief dared to imitate it, but he could not control the rest of the country.

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

　　 "His Royal Highness, these four are clearly stealing lessons." Luluo said contemptuously.

　　 Xiao Ming smiled faintly: "Hey, you can learn by stealth. It's not certain whether you can learn."

　　 After finishing speaking, he turned and looked at the fields along the Xiaoqing River. Lu Fei’s winter conscription has ended. Five thousand recruits and three thousand remained in Qingzhou, and the others were assigned to other states and counties.

　　 Lu Fei’s heart grew stronger because he got one million taels of silver. In the spring, he still didn’t stop conscription. He discussed with Lu Fei and planned to conquer another 5,000 people and control the fief’s army to 13,000 people.

　　If there is sufficient food in Qingzhou in the coming year, he will consider continuing conscription.

　　 Among the newly recruited people, Xiao Ming asked Lu Fei to pick out some fishermen's children along the coast.

　　 Naval construction is not a matter of overnight, just finding a direction in the sea is a problem.

　　 The so-called basic SH ship for navigation in this era travels along the mainland so that it will not lose its way. Xiao Ming selected these people to train 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 in his field, recruits are pulling cattle to reclaim the land, and hundreds of cattle are busy pulling plows.

　　 In other uncultivated places in Qingzhou, Lu Fei also took the soldiers under his hands to reclaim the land.

　　 In order to allow the Construction Corps to quickly mobilize the fields, this time Xiao Ming equipped the Corps with the best farming tools. Not to mention sufficient cattle, this is the first time that the cattle power dump has been delivered.

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

　　 Luluo followed Xiao Ming's gaze and said with a smile: "His Royal Highness, this is the first time I have seen soldiers in this place."

　　 Xiao Ming knocked Luluo on the head, "Follow this king, UU read www.uukanshu.com, how many things did you see for the first time?"

　　Walking around the cultivated land, Xiao Ming checked the reclaiming situation, and then went to Qingzhou City with Luluo.

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

　　, like his fief, is a place full of hope.

　　 After two or three months of busy work, he invented a lot of products that the country did not have, and these products are also expanding their influence to bring him continuous profits.

　　 But the way forward is unknown, he dare not relax at all.

When 　　 was born in the royal family, sometimes he couldn't help himself, and if he didn't move forward, there was an abyss behind him.

　　 Entering the city of Qingzhou, Xiao Ming smiled by the shuttle of foreign merchants. Now he has taken at least the first step. Next, he will attract more merchants to buy land and build workshops in Qingzhou.

　　The goods produced from Qingzhou are then continuously shipped to all parts of the country, bringing huge profits.

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

　　 Perfume, soap, and liquor are only the lowest-end in Xiao Ming's eyes. Niu Li has a little bit of science and technology, and countless technologies in the science and technology library are still waiting for him to become actual commodities here.

　　 But now Xiao Ming realizes a problem, that is, his fief is severely lacking technical talents, and Pang Yukun has set a good precedent for sending craftsmen from various states and counties to study.

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