golden scales

In April of the sixth year of Longjing, "Emperor Ming Bulletin" spread the good news again that Empress Duan gave birth to a son safely, named Zhu Heyin and recorded it in the genealogy.After the Taizu, there were very few emperors of the Ming Dynasty who were so prolific, especially since all the sons were born in the middle palace, and none of them died young, which is rare in ancient and modern times.Qin Tianjian is almost going to report it to auspiciousness and record it in the annals of history.

Empress Duan hadn't confinement yet, Zhou Hou had already been urged several times, and had to go out with the Supreme Emperor Chongzhen.When she came to Baoding, she was still thinking about her confinement daughter-in-law, and even wanted Concubine Yuan to accompany Chongzhen Nanxing, and then returned to Beijing by herself, but was finally persuaded by the female officer around her, and there was no trouble.

The so-called pillow has no saints, as the wife of Chongzhen, Zhou Hou has no fear of the emperor at all.

Zhu Cihong sent his father, queen and mother outside the gate of Daming all the way, and finally settled a major event.Although Emperor Nanxing's project has indeed had a considerable social effect, and even the commercial level of the areas along the route has developed significantly, the feeling of being pushed all the time is not good after all.

Duan couldn't go out to see the wind, couldn't see him off, so naturally he wasn't in a good mood.She was not worried about her aunt, but about Qiu Guan.Even though she knew that the crown prince would not suffer hardships along the way, the worry of the mother who traveled thousands of miles could not be exempted.As soon as the emperor and the crown prince left, the palace seemed much deserted.Zhu Cilang simply started the overhaul of the Qianqing Palace, mainly to build sanitary water intake and floor heating pipelines.

At present, the traditional heating methods in the palace are ground fire dragons and fire walls. Although the effect is good, it is also a waste of money.Many officials, gentry and large households have started to use copper and iron radiators for heating with circulating boiler water, which is trendy and affordable compared to the traditional fire dragon wall.

Although Zhu Cihong is still concerned about Zhu Hegui's ideological problems, but thinking about when he first entered the university to study law, he was also full of innocent feelings of upholding justice and defending legal beliefs.But after all, he became a realist in pursuit of success, so the crown prince might turn in reality and return to himself in the future.

With the advancement of the renovation project of the Forbidden City, Zhu Cihong also had time to sort out various civilian technologies of Ming Dynasty.From a general perspective, Daming is still following the road of steam mechanical civilization.Because of the continuous progress of steam engines and metallurgical technology, some factories and mines in Liaoning have begun to lay rails.The use of steam locomotives for short-distance transportation has sprouted.

From a small point of view, mining forged cement is obviously very profitable, so that now people in all counties and counties across the country have opened cement factories.These factory owners are not all aiming at making money, because many officials, gentry and big households adhere to the "small peasant consciousness", but they produce everything they need by themselves.Because my family needs to build a house and repair roads, I simply set up a cement factory to burn cement, not only can I get cement at cost price.It can also be sold to neighbors and even the imperial court.Because transportation costs are still high, the imperial court is more inclined to purchase locally.

Of course, prefectures and counties with conditions will also set up government-run cement factories, but the officials who do this are mainly to promote the transition of the professional population and gain political achievements.Among them, many officials were also sacked because of corruption, but because of poor management of the cement plant.lead to failing the exam.

"How is that thing made?"

Zhu Cihong leaned on the back of the chair, trying hard to search for the memory from half a century ago.

indeed.That is the dividing line between the two eras, and it is also the key for mankind to truly enter the era of science and technology.It does not require a detailed accumulation of knowledge, and even primitive people can verify it through the senses.

That is electricity.

To say that electricity and magnetism are inseparable.As early as hundreds of BC, the Chinese invented the compass, and the Greeks also discovered the phenomenon of static electricity.Later, the compass became a compass, and Europeans also discovered that friction can artificially create static electricity.However, according to the historical script of Zhu Cihong's previous life.Electricity, which can truly revolutionize productivity, will not appear by accident for another century and a half.

It was an accident caused by a frog's leg.

When the Italian scholar Galvani was treating the frog's leg for his wife, which was a drug in Europe at that time, he accidentally discovered that the frog's leg convulsed when he touched the frog's leg with a metal fork.

This phenomenon is discharge.

Of course, Galvani noticed this phenomenon.But I don't know what I found.He had to go through a lot of experiments to rule out the electrification of the tableware, the bioelectricity in the frog's legs, external influences, etc., and finally found that as long as two different metals are mixed with salt water, the conclusion that electric current can be generated.

These are of course meaningless to Zhu Cihong, even with the science level of a liberal arts student, he can directly copy the voltaic pile.

Volta is a friend of Galvani. Based on Galvani's experiments, he used zinc and copper sheets to sandwich paper sheets soaked in salt water to form a stack to generate electric current. This device was later called voltaic electricity. heap.He also put zinc sheets and copper sheets in a cup filled with salt water or dilute acid, and connected several such small cups to form a battery pack to increase the current intensity.

Zhu Cihong no longer remembers the various metals in the full voltaic sequence, but he is not worried. It only takes one day for the graduate students in the university laboratory to make this arrangement experiment.

In addition to having a power source, you also need wires.Both silver and copper are excellent conductors, and one only has to look at the cloisonné enamelware in the palace to know that it is not difficult to make experimental wires.As for the outer insulation, dry wood can be used, and if the experimenter is careful, the insulation is not even needed.

If the light bulb can be made, the whole electric current lighting experiment will be completed.

Well, that would require "inventing" the light bulb.

At that time, Edison also worked hard on the material of the light bulb, and conducted a lot of experiments. Finally, he obtained bamboo charcoal silk that can emit light for a long time as an ideal material, and manufactured the first incandescent lamp.Of course, the investment of time and materials can also be saved, and Zhu Cihong can directly ask people to prepare bamboo charcoal silk.

Although there is no way to fill inert gas and find rare tungsten, for experiments and the emergence of science, even if it is only a short period of light, it is enough to be recorded in the annals of history and lead the future.

What really troubled Zhu Cihong was the manufacture of hand generators and wired telegraphs.

Although the principles of both are very simple, only coils and magnets cut magnetic force lines to generate current, and wired telegraphs only need to be made in the laboratory at present, and it is enough to transmit "ticks" and "ticks" and long and short lines... But Zhu Cihong is not really talented in mechanical design, and the hand-cranked generator and the cable telegraph have only met once in the illustrations of books. After decades of separation, it is not easy to reproduce them?

"Suyao," Zhu Cihong called, "ask Song Yingxing to bring fifty outstanding teachers and students to Beijing immediately. Inform Jingshi University to prepare one hundred physicists, settle down family members, and prepare for a high-secret project."

Lu Suyao hadn't seen His Majesty the emperor so excited for a long time, she also lifted her spirits and said: "I will inform you now."

"That's right! Ask the Inner Palace Supervisor to prepare an experimental field, enough for 150 people to live in. The laboratory... can't be smaller than the sum of Wuying Hall and Wenhua Hall. Before Song Yingxing and the others arrive in Beijing, it must be ready. As for the new building It doesn't matter whether it is rebuilt or not." Zhu Cihong said.

……

"what is this?"

At the waist of America thousands of miles away, Zhu Hezhi was holding a gray-white sphere in his hand.This sphere is not very round, but it is quite elastic, and it is made of a material that has never appeared in Ming Dynasty.

"Return to Your Highness," the guard who found the ball replied, "This is a game played by the locals..."

"I know it's a ball." Zhu Hezhi interrupted the guard: "I'm asking what kind of material this ball is made of. My Ming Dynasty doesn't seem to have such a thing."…

"His Royal Highness, I have already inquired about it." The clerk at the side hurriedly stepped forward and said with a charming smile: "There is a kind of tree here, which the natives call the tear tree. When the tree is cut open, milky white resin will flow out. The ball is made of resin."

Zhu Hezhi squeezed the resin ball vigorously, and murmured, "What can this thing do?"

"This thing is suitable for use with charcoal pens." The clerk smiled and said, "In the past, when charcoal pens made mistakes, they could only draw a circle. The officer tried to use this resin ball to wipe it, and found that it could actually write charcoal pens. Wipe it off...although it's not very clean."

"It won't be useful for this." Zhu Hezhi was a little disappointed.Charcoal pencils were not originally used by the rich and powerful. For example, he himself had never used charcoal pencils before boarding the ship.That being the case, what good is a tool for erasing charcoal writing?

"Anyway, it's a local product, so you can take it home and make it into a ball for children to play with," said the former guard.

So far, Zhu He had completed his last supply from Kuwu. The fleet went straight north along the coast, crossed a strait to be named by the emperor, and arrived in the northern part of the American continent.

Because of the ice and snow there, the dry and cold climate, the fleet traveled south along the mainland after dropping the boundary markers, and found several prominent landmarks hand-painted by the emperor, which shocked His Majesty even more.

It was not until the fleet entered New Spain that Zhu Hezhi got real supplies.The remaining Ming merchants on the ship earned him the capital to continue going south, and finally came to the waist of America, which is the dividing line between the north and the south of the American continent, and has the style of another world.

"Why bring such a worthless thing back..." Zhu Hezhi was about to veto it, but then he thought that what he brought back was all the things that the Spaniards had already sold, and there was no benefit in offering it to the emperor.Although the tear tree is useless, Daming doesn't have it!Things are rare and expensive, but they can also be counted as tributes.

"Take less," Zhu Hezhi changed his words, "It's almost enough to move fifty plants. The seeds don't take up space anyway, so bring two or three sacks for preparation. I think this tree looks beautiful. I don't know where it is. Can Beijing grow a living."

ps: Today, this piece is open again. I wonder if someone will open their minds and amplify the laboratory level to the industrial level to criticize Xiaotang?
