The rolling mill made in this way cannot be too powerful, and the operation is very complicated, but fortunately it is rolling copper sheets instead of steel plates. Although there are many problems, it can still be used with difficulty. The failure rate is also very high, and it can only continue to make people

Carry out repairs and prepare a large number of spare parts made of iron and wood.

Moreover, they cannot perform continuous rolling. They can only roll copper plates piece by piece. First, the copper material is rolled into thick copper plates, and then it is lifted to another rolling mill and continued rolling to make it thinner.

By adjusting the distance between the rollers repeatedly in this way, the copper plate is gradually rolled into copper sheet.

Just the process of rolling the copper sheets wasted a lot of their time. After the ship was modified, just waiting for the copper sheets wasted a lot of time.

Nanri Island's own water resources are very limited. Currently, it is only enough to support their personnel use and agricultural irrigation. The reason why Yu Xiaotian wants to transfer industry to fresh water is because Nanri Island's water resources are not rich enough, which has restricted industrial development.

important factors.

Therefore, the rolling mill for rolling copper plates requires water power and can only be produced in fresh water. It took a long time to roll the copper sheets back and forth.

After testing, they found that the thickness of the copper sheets they rolled themselves was only about one millimeter, which was much thinner than hand-made copper sheets. In addition, the quality was also very uniform, which was much better than hand-beaten copper sheets.

Although their rolling mills are thick and stupid, have extremely high failure rates, and are very troublesome to operate, they are still a hundred times better than manpower. Several sets of extremely crude rolling mills, and the copper plates rolled every day, can make these workers,

Even if you work for more than ten days, you may not be able to catch up.

This is the power of industry. Once machinery is put into use, even the simplest machinery, the production efficiency will be much higher than that of a purely manual small workshop.

As production efficiency increases, output increases and production costs decrease. This is why after the industrial revolution, large-scale small workshops were unable to survive, causing a large number of them to go bankrupt and ultimately being hired as industrial workers by factory capitalists.

The development of industrialization also requires a large amount of manpower. These small workshop craftsmen can be absorbed into industrial workers, and a large number of manpower can be absorbed into factories to work, freeing up more land and forming a specialized working class.

The development of industrialization will produce a large number of products, and industrialized products need to be consumed. This also encourages capitalists to sell their goods. The country will definitely not be able to consume a large number of goods, so they will dump them abroad.

Dumping overseas requires a market, and occupying the market sometimes requires force to ensure it. This is one of the reasons why global expansion began after the Industrial Revolution in Europe.

In modern times, China has never carried out an industrial revolution, and has always been engaged in small workshop-style production. Naturally, the country does not need to dump a large amount of goods overseas, and capitalists will not vigorously promote the development of force. So in the 18th and 19th centuries, China became

It became a poor and backward country and became the meat of the European powers, including the newly rising Japanese in Asia.

Therefore, at this time, Yu Xiaotian decided to spare no effort to promote the industrialization process, at least within his jurisdiction, to promote the development of mechanized production on a large scale to change the course of historical development.

Yu Xiaotian now has considerable strength. He would not consider these things before, but now he has begun to seriously consider future development issues.

He is no longer satisfied with his original idea. He is just satisfied with supporting his own troops, occupying a corner of Taiwan Island, and surviving in the troubled times in the future.

As his power grows, he considers more and more things, and they start to look further and further away.

However, these words were a bit far-fetched. At the moment, he was still concerned about the problem of the ship. After the copper problem was solved, the renovation project of this three-masted Dafu ship began to become smoother.

In addition to copper sheet, there is another problem in how to cover the bottom of the ship with copper sheet, that is, iron nails cannot be used, because after the contact between iron and copper, there will be electrolytic corrosion problem in sea water, so

Copper nails must be used, and people in this time and space have no idea about this. Initially, the boathouse planned to use iron nails to nail these copper nails to the bottom of the ship and pull it down.

However, Yu Xiaotian immediately stopped their recklessness and ordered that copper nails be specially made as a means of fixing the copper skin without any expense. Copper nails must be used instead of iron nails to cover the bottom of the ship with copper skin. Otherwise, it will not take long.

, the copper skin on the bottom of the boat will undergo an electrolytic reaction with the iron nails in the sea water, and eventually corrode and rot, losing the role of protecting the bottom of the boat.

For this reason, the British also encountered such a problem. After searching for a long time, they discovered the problem of fluid electrolysis reaction in seawater when copper and iron contact each other. They solved this problem by replacing all iron nails with copper nails.

As a latecomer, Yu Xiaotian certainly knew these things, so he could not take such detours again and directly solved this problem in one step.

In addition, he also explained the reasons for doing this to the craftsmen in the boathouse. However, for these craftsmen who were once illiterate, talking to them about such a chemical reaction was obviously difficult for them. No one but Xiaotian

I can't tell them anything more for the time being, just let them understand that they can't use iron nails for the time being.

As for education, he can only place his hope on the schools he has opened now, starting with the children and providing them with a more systematic education, and only then can the cultural quality of the population be improved.

But now his biggest headache is probably the issue of education.

Although Yu Xiaotian attaches great importance to cultivating children and teenagers, he has opened schools in Nanri Island, Tamsui and even Keelung Fort to absorb the children of the Sea Wolf tribe under his command and the children of the people within his jurisdiction, and even a large number of people from the mainland.

Collect orphans and place them in schools for education.

However, he seriously lacked teaching resources, because very few scholars in this era were willing to become thieves. There were only a handful of scholars like Lin Yiyang who were forced to have no other choice before joining his service.

The cultural education in ancient China attached great importance to the so-called loyalty education. It is not just a matter of words to sell the learned arts and martial arts to the emperor's family. The purpose of scholars studying is to be named on the gold medal list one day and obtain an official position from the imperial court.

He rose to the top of this society, and scholars extremely despised thieves like Sea Wolf and others.

Therefore, although Yu Xiaotian has been trying to attract some scholars to work for him through various means over the years, even resorting to violence, kidnapping or inducement, the results have not been good.

Even if many scholars are poor, they are not willing to work for him. The reputation of a thief makes them feel that it will bring shame to their ancestors. Therefore, in the past few years, the scholars that Yu Xiaotian has obtained are the highest.

With the academic qualifications, they are considered to be scholars at best, and there are only a dozen or so of them.

However, there are only a few of these people who are really dedicated to working for him, and the more common ones are only some children. At best, they can only read a little and can write and calculate things.

Therefore, the most serious lack of teacher resources in his school is that although he arranged for a group of scholars to serve as teachers in the school, there are very few things these people can give to the students. They are just some old things like the Four Books and Five Classics.

Teaching these things to students may not necessarily do him much good.

Because most of what the students learned from these things was loyalty to the emperor, which had a negative impact on him, he really couldn't come up with much useful things in terms of teaching materials, and he really didn't have much time himself.

, to write the teaching materials myself.

Among these teachers, very few know anything about the study of things, and it is impossible for him to personally teach students any courses in algebra, geometry, physics, chemistry, biology, mechanics, etc. at the moment.

Therefore, although he has run several schools, they can only be regarded as literacy schools in essence, allowing students to learn to read and write first. As for how to educate them in the future, he can only postpone it for the time being. In addition, students who pass literacy education can also be given to craftsmen.

Conduct literacy exercises with the Sea Wolf tribe.

At present, the so-called educational work he is doing is basically stuck at the literacy stage. If he wants to take a step forward, he has encountered great difficulties. How to solve this problem, he still has no good solution.

After he recovered slightly, Yu Xiaotian went to the pier to inspect the deeply modified Dafu ship. The ship had indeed been modified according to his vision. The ship now has sails and ropes.

Everything is ready, and the artillery has also been installed in place, and several trials have been carried out.

At present, it seems that the transformation of this ship should be quite successful. After the transformation, the center of gravity of the ship has not been significantly changed after careful trim adjustment and the installation of artillery. Even if a large amount of cargo is not considered,

After increasing the weight of the ballast stones on the bottom of the ship, the center of gravity of the ship has also been lowered.

As a result, the stability of this ship has been improved to a certain extent when sailing at sea. Under normal sea conditions, this ship can carry out normal battles. After the gun window of the gun cabin is opened, water will not enter.

Even when the sea conditions are relatively bad, it will affect the lower gun cabin and the closed gun window cannot be opened, but the upper deck cannon can still be used normally, so overall, the transformation of this ship is relatively successful.

This is also a success achieved on the basis of the previous modifications to several No. 2 Fu Ships. Without the initial experimental modifications on other ships, it is estimated that it would be difficult to directly modify this ship to such an extent.
