The Dadu Port, that is, Panzhihua, gave Zhu Changhao a situation in which the southwest strategy finally converged, but this is the first step in integrating the southwest, and it also indicates the arrival of a new prosperous stage in the southwest.

Since the Han Dynasty, due to factors such as humid heat and inconvenient terrain in the southwest, the population has never been greatly improved, even on the peninsula south of western Guangdong, there are only human tribes on the plains formed by silting up on both sides of the river, and other places, not to mention.

Now after these places are consolidated, Zhu Changhao plans to tidy up the Wusi-Tibetan area, which is the highest plateau in the southwest, and must strengthen the local management of the imperial court. In the future, the Ming Dynasty will make a large number of steam trains, for the Wusi-Tibet region, to build a railway, it is also possible, but I am afraid of the so-called frozen soil problem, after all, this is the category of climate, to overcome the work of frozen soil, Zhu Changhao believes, that is, in the summer, to build a railway.

But on the plateau, generally speaking, June and July are the best months to build railways, and it is a little cold in May, and in August, it is not good. But the current level of industrial science and technology in the Ming Dynasty, that is, this level, the plateau railway, can only be built for two months a year.

This winter, Zhu Changhao plans to study with the subordinate officials of the palace, what should the Rui Wangfu do next year, what is its goal, and what are the processes and means?

After Zhu Changhao made a hand-cranked generator in the treasure hall in the palace, he immediately asked Sun Yuanhua, Song Yingxing, Dai Cang and others to be invited to the palace to explain to them the use of this thing.

When Zhu Changhao used a copper ring and an iron ring to fix the copper ring and the iron ring under the two magnets, tied a copper wire and iron wire respectively, and then put it in a porcelain basin filled with water, after shaking the rotor, he saw that the porcelain basin was constantly blistering, Zhu Changhao asked Dai Cang to shake the rotor, and held a reed rod with only Mars left in his hand, and at the end near the copper wire, the reed rod of Mars burned at once.

Near the end of the wire, a green flame generated on the surface of the water, but the reed did not burn.

After this test was completed, Zhu Changhao said, "Three, this test is called the electrolyzed water test. The bubble that made the reed rod burn just now is called oxygen by the king, and the bubble that produces a light blue flame on the surface of the water behind it is called hydrogen by the king. These two kinds of bubbles, the first we can use to weld iron plates, steel plates, and can also save people when they are dying, and the second one, we can burn, and we can also remove some rust spots such as patina and rust. ”

Next, the three of them tried it again, and it was as the prince said.

Zhu Changhao saw the interest of the three of them, and said, "Our ironclad ship, in the future, will collect the gas that makes the reed rods burn, compress it in the cylinder, and then release it through the guò iron can, and then ignite it to melt the gaps between the steel plates, and then weld it." ”

The evolutionary history of human industry is often changed by small things, and those small changes in the past are caused by human beings unconsciously.

Thinking of this, Zhu Changhao felt that the Ming Dynasty had not experienced such trends as the "Renaissance" and the "Enlightenment", which would cause people's lack of the spirit of scientific inquiry.

Daming Royal University of Science and Technology, Zhu Changhao plans to give the students inside a winter vacation this winter. This winter vacation, it can be said that the seven royal schools outside Hanzhong Mansion will not have a holiday, Zhu Changhao took advantage of the rare vacation, to teach the students of these seven universities, to instill modern industrial civilization, the concept of the legal system, patriotism, the most important thing is to emancipate the mind, to make them understand that morality is important, law is more important, and the survival needs of the Ming Dynasty are extremely important.

That is to say, in a certain way, they must abandon the concept of Confucianism, and change the concept of the Ming Dynasty from "guard dog" to "steppe wolf".

This is just an improvement of the minds of adults, but for the Boy Scout Academy, Zhu Changhao will not relax, and his own guards will be based on these Boy Scouts in the future.

To tell the truth, starting next year, the first batch of scouts will leave the school, their age is almost seventeen or eighteen years old, their thinking is that can stand the test, besides, the children in this are all orphans, most of them are the seven years of the apocalypse, the people who escaped from the famine, and now after three years of brainwashing, Zhu Changhao believes that this group of people will be the mainstay of implementing his orders in the future.

There are a lot of complicated things, in addition to starting lectures every day, Zhu Changhao went to the ordnance supervision in the afternoon to see how the electrolytic water and oxygen welding equipment is now configured.

This configuration is basically no problem, but it is quite laborious to move, if you turn the iron pipe into a hose and put an iron nozzle on it, it will be much easier.

Therefore, Zhu Changhao decided to send people to the south to contact the Portuguese and Spaniards in Guangzhou, and let them transport a batch of rubber tree seeds from the Americas to mature.

For every kilogram of seeds, they were paid 500 silver dollars, but they had to ensure that the seeds took root and germinated.

Zhu Changhao handed over the matter to the royal firm of Guangzhou Mansion to deal with, and after paying a deposit of 1,000 silver dollars, the Portuguese merchant agreed to the matter.

It just so happens that now is the time when the prevailing westerly wind rises, starting from the port of Guangzhou, and going straight to the Americas.

It's just that this rubber is shipped back, and it will be next summer, after five or six years, it can be large-scale rubber tapping.

But it doesn't work without gum, Zhu Changhao immediately asked the ordnance supervisor to find a way, and someone really came up with it.

Use pine, cypress, as well as pepper trees, peach trees, fish bone glue, pig trotter glue, cow tendon glue and other gums, mix them together, and then boil them, brush heavy oil on the iron rod, and when the heavy oil volatilizes almost, leaving only the black-brown carbon black on it, immediately brush the glue on it, and then wrap a circle of cotton thread on it, and then brush a layer of glue.

After the two layers of glue have dried, apply one layer to the brush. Finally, twist the hose and let it squeeze out of the iron bar.

Then test the airtightness and the pressure you are subjected to.

In this way, this hose mixed with animal glue and vegetable glue is finally made, on the brown and yellow bright colloid, you can also see that there is no melted rubber particles at all, and in terms of ductility, it is not as good as natural rubber, but at present, it can solve the problem of mobile oxygen welding and the air tightness of the oxygen tank.

Before Zhu Changhao reminded the three ordnance supervisors that the bio-glue manufactured was registered at the patent yamen, Sun Yuanhua had already written the materials, as well as the relevant gelatinous objects, and the hose to the patent yamen.

This rubber is there, and I am going to make glass when I make it. I used to think that a lot of travelers made glass and soap, but I didn't think that I would still take this old road of invention.

For making glass, it seems that in the 21st century, there is a chemistry textbook in middle school, Zhu Changhao remembers that it is made of sea sand, quartz sandstone powder, soda ash, dolomite and other raw materials, prepared according to a certain proportion, melted at high temperature in the melting kiln, the liquid glass flows continuously from the pool kiln to and floats on the surface of the molten metal, spreads into a glass strip with uniform thickness and is polished by fire, cools and hardens and is separated from the molten metal, and then annealed and cut into transparent colorless flat glass.

The specific proportion is not clear, but Zhu Changhao decided to let the craftsmen of the Ordnance Supervisor try it, knowing that they would try to make the best proportion.

For soda ash and dolomite, when the Ming Dynasty made steamed buns, it was already used, dolomite in Mianxian County, Hanzhong, as well as Ningqiang, Luoyang, this process is not complicated.

When Zhu Changhao finished these ingredients, he asked people to fire them in proportion, and emphasized that the bubbles in the glass must be reduced.

Almost eight tests were done in a row, and on the third day of the lunar month, Sun Yuanhua reported that the ordnance supervisor had made glass, but because of the primitiveness of some processes, the glass was only the size of a palm, and there was a green halo on it.

But Zhu Changhao is already satisfied, for glass, you can use the levelness of the liquid glass at the beginning, and use the blow molding method to blow it into glass utensils that can hold utensils, but the Damingrui Mansion is still in the exploration stage.

When Zhu Changhao saw these glasses, he said, if you use mercury to stick tin foil behind the glass, it will be a way to make a fortune.

As a result, with the encouragement of Sun Yuanhua, these craftsmen of the Ordnance Prison used mercury and pasted tin foil or silver powder to really get a brilliant glass mirror.

When Song Yingxing came to the palace with a mirror in the carriage, Zhu Changhao knew that he had an extra way to get his wealth.

Later, the patent for the manufacture of glass, as well as the method of manufacturing mercury powder mirrors, were registered with the patent yamen.

Since Zhu Changhao was the initiator, he still had a copy of this patent, but Zhu Changhao didn't ask for it, and still used the reward mechanism to send silver dollars to the inventor, as well as certificates such as master craftsmen.

Oxygen welding, hoses, glass and glass mirrors were completed, and on the third day of the lunar month, the income of Chongzhen in the prefectures and counties of the 3,000-mile waterway of the Han River was reported in Hanzhong, and Zhu Changhao found that the tax revenue obtained this year reached 60 million silver dollars.

And from heavy industry steel manufacturing, shipbuilding, to light industry textiles, as well as all kinds of food processing, wood furniture, the entire Ruiwangfu sphere of influence, are light and heavy industry at the same time, the service industry is needless to say, inns, green buildings, tea shops, music shops and so on.

In a word, after nearly three years of development, Zhu Changhao, the prince of Hanzhongrui, has been full-fledged and has obtained the capital to compete for the world.
