R&D equipment, sometimes to adapt to local conditions, like ball grinding machine, Yang Wenli has a unique design.

After the small steel rod is extruded by two hemisphere molds, it shows the rudimentary shape of the ball, but there are more burrs, and it is not absolutely smooth, which requires grinding, grinding is divided into fine grinding and coarse grinding, modern is the rough grinding of ball mills, but the equipment is too complicated, Yang Wenli has developed a simple and efficient coarse grinding equipment.

The principle is very simple, it is a fixed rotating screw rod, and a mold is set on the outside, but this mold is a shape with a large end and a small end.

The big end is put into the rough embryo of the ball, the ball is pushed forward by the screw, because the outer mold continues to shrink, the burr of the ball is constantly flattened or broken to remove, to the back section, the gap between the outer mold and the screw is just the diameter of the ball, as long as the force is large enough, the ball is forced to squeeze to round.

The final fine grinding is actually polishing, Yang Wenli uses a kind of oil stone, grinds it into powder, and then uses fish glue to dip it into a coarse cloth to make a primitive abrasive cloth and grinding wheel, and carries out manual mechanical polishing.

The key here is this kind of oil stone, Yang Wenli has no scientific instrument analysis, I don't know what substance it is, but it is extremely fine after grinding into powder, comparable to the fineness of the gray surface, and has natural oiliness, after the ball is finely ground, it is extremely bright, like a mirror, the light can shine on people, it is an extremely rare high-quality natural abrasive.

"Wow! Your Majesty, after the balls have been finely polished, how can they be so smooth and shiny! It's almost time to make gems. Yang Liren picked up a finely ground ball and smacked and exclaimed.

Yang Wenli also picked up a ball and measured it with his perverted divine sense, (Note: It can't be measured at all with ordinary tools.) Finding that the balls were extremely standardized, the diameter was surprisingly consistent, and the error was several zeros after the decimal point, and he measured several pieces one after another, all of which were so, so he couldn't help but nod with satisfaction: "Yes, these balls are qualified, and in the future, they must be made in large quantities, and this kind of balls must be used as a standard." ”

Yang Wenli's words were said casually, and they had nothing to do with Yang Liren, it was Wang Rucheng's work, so Yang Liren asked him again: "Your Majesty, what else do we have to do now?" ”

"Let's cast the inner and outer jackets of the bearings, and then assemble two bearings to try." Yang Wenli replied casually.

"Whoa!"

In this way, Yang Wenli took the slave soldiers tirelessly to do various experiments, first developed the bearing, and then made persistent efforts to develop hot extrusion equipment, straightening machines, primitive transmission belts and so on.

This original transmission belt is a steel shelf, the steel rod in the middle is not fixed, can be rotated, this is because when the wire drawing machine straightens the steel pipe, the steel pipe is still red-hot, there must be a straight and horizontal frame to support it, do not bend the steel pipe.

This busyness is another ten days and a half months of work, and during this period, the changes in Sapporo can be described as a thousand miles in a day.

Because they are all low-rise residences, the highest is only a four-story building, and it is built in a cement frame style, and the speed is so fast that it flies, and one building after another rises from the ground.

There are special foundations, there are special houses, there are special paintings, there are special decorations, and the final landscaping, we have divided labor and cooperated, forming an assembly line operation, and its construction speed must be described with Shenzhen speed.

People are divided into grades, of course, the construction of houses is also in order, the first to build is Yang Wenli's palace, the shape of the palace is in European style, in fact, it is borrowed from the architectural design style of the Palace of Versailles, but there are no exquisite sculptures and complex decorative strips, no matter from the outside to the inside, it is a simple design style, simple but not simple.

Yang Wenli's royal palace is three main buildings in the shape of a zigzag, and the main hall facing south is the living place of Yang Wenli and his wife, as well as the place where the court meeting was held.

As the king of a country, his residence can not be shabby, the scale is not inferior to the Palace of Versailles, not counting the underground overhead layer of up to one meter five, it is also a two-and-a-half-story building, the upper half floor is a thermal insulation layer, the total construction area has also reached an astonishing 110,000 square meters, the main hall alone is 670,000 square meters, there are more than 500 large halls.

Ezo Island is one of the best places in the world to refuge, and although it is only a temporary palace, it cannot be too shabby as a palace for the future royal family, so Yang Wenli designed such a large scale.

The square in front of the main hall is also designed with a huge fountain, because there is no electric motor for the time being, so this fountain may be the only living water fountain in the world, the water comes from the dam established on the mountain, and the gravity is used to make the fountain, so that this pool of tens of thousands of square meters is not dead water, but living water, which can ensure that the water quality is clean and does not rot for many years.

The remaining two auxiliary buildings, temporarily used as the office space of the government department, will be the office of the palace guard and the royal family institutions in the future, now, the royal family is very shabby, only Yang Wenli and his wife, there are not so many rooms, in order not to waste, so it is diverted for other purposes.

It must be explained that the Palace of Versailles in France took decades to build, the main reason is that the main body of the Palace of Versailles is a marble building, which takes a lot of effort, and the Far Eastern Kingdom is a concrete frame building, without complicated sculpture and craftsmanship, and sufficient manpower.

The large army led by Yang Rentian came back at this time, and everyone was stunned by this huge and exquisite building complex, you know, not long ago this was still a dense primeval forest.

As if they had been promised a spell, such a huge complex rose from the ground overnight, do you think they could not be surprised?

Among them, Taricona is completely convinced, big power or big power, not at all his small tribe can be invincible, from the perspective of this grand palace, they are indeed going to live here for a long time.

Matsumae Gonghiro, who is in the ranks of the logistics troops, is a mixed bag, thinking that his Matsumae family arrived on Ezo Island more than 200 years ago, and for such a long time, it is not as good as the achievements of others in a month, it is really ashamed to say it, it seems that what His Majesty said, he is bringing civilization rather than destruction, it is true, the people of China, it is really not simple.

When Yang Rentian led his generals to meet Yang Wenli in the king's tent, he was told by Yang Renhong, who was in charge of the outer guards: "Big brother, brothers, Your Majesty is not in the tent, he went to the factory to conduct experiments, every day, you go back to rest first!" Come back tomorrow morning. ”

Yang Wenli's hobby, several of their brothers knew, so it was not surprising, Yang Rentian replied on behalf of everyone: "Well! In this case, I will go back to settle the troops first, and come back tomorrow to see Your Majesty, and goodbye to the seventh brother! ”

"Goodbye!" Yang Renhong raised his hand and saluted.
