Zhu Youzhen just wanted to touch the feel of silk, but he didn't know that he touched a hard thing.

When I took it out, it turned out to be a very beautiful jade.

When he saw the appearance of the jade clearly, Zhu Youzhen suddenly said a slump.

It's exactly the same as the legendary jade seal.

Its square circle is four inches, on the new hand over five dragons, the front is engraved with the eight seal characters of "ordered by the sky, both longevity and Yongchang", in order to serve as the token of "the imperial power is granted by heaven, orthodox and legitimate".

Zhu Youzhen suddenly burst into ecstasy:

"Hahaha, it's really effortless to break through the iron shoes and find nowhere to get them, don't look for Lao Wang, the jade seal is here."

This is indeed the piece of jade seal that Huang Taiji obtained, when Dolgon Da Yu'er fled in a hurry with Fulin, the jade seal and some close-fitting clothes were taken by Da Yu'er, she didn't let anyone know, even Dolgon didn't know.

After these people escaped from the tunnel, they were caught by Huang Degong, and Huang Degong, a big man, didn't pay attention to it, and threw the cloth bag into the pile of gold, silver and jewelry when he went back.

Although the soldiers were very jealous of so much gold and silver, but now the Ming army has strict military regulations, and no one dares to touch these gold and silver jewelry, resulting in the world's largest treasure drowning in the pile of gold and silver.

If it weren't for Zhu Youzhen remembering his inner money, if it wasn't for the system reminding him, I really don't know when the jade seal would come out.

Hearing that the jade seal had been found by the emperor, Lao Wang quickly ran to Zhu Youzhen's side.

Excited, he forgot his identity, and reached out to take the jade seal and look at it carefully.

"That's right, this is the jade seal, exactly the same as the legend, congratulations to Your Majesty, congratulations to Your Majesty, the jade seal of the country was finally ...... by the Ming Dynasty"

Lao Wang fell to his knees, raised the jade seal high above his head and handed it back to Zhu Youzhen.

Those Dongchang fans also knelt on the ground together, shouting long live my emperor.

Regarding Lao Wang's recklessness, Zhu Youzhen didn't feel anything unhappy, knowing that he was excited for a while, and it was also because he had Daming in his heart.

"Haha...... All quickly flattened, and each person was rewarded with five hundred taels of silver. ”

Zhu Youzhen asked everyone to be even, and each person was rewarded with five hundred taels of silver, which made those fans happy.

Five hundred taels of silver is nothing to Zhu Youzhen, but for those fans, it is definitely a big fortune, and they can find a wife to live a good life.

The emperor spoke golden-mouthed, saying that the reward would definitely be rewarded, and after they thanked the emperor, they withdrew from the treasury after receiving the reward.

But Wang Chengen didn't move, Zhu Youzhen patted Lao Wang's shoulder and smiled:

"Lao Wang, go get it yourself, and pick any gold and jewelry."

Lao Wang bowed and saluted:

"Your Majesty Longen, the slave has no family and no descendants, and it is useless to ask for too much silver."

Seeing that Lao Wang didn't want to reward him, Zhu Youzhen didn't force him, but Zhu Youzhen wouldn't let this loyal old eunuch suffer.

"Old Wang, I know that you are loyal, and you will live in the palace until you are old, and I will support you!"

"Thank you, Your Majesty Longen, how can the slave and maid be so virtuous, and let the saint treat him so kindly......"

Lao Wang was excited at first, and now he is moved again, and he can't help but cry.

"Thank you, Your Majesty, Longen!"

As the weather gets colder and colder, the briquettes produced by the Xishan Coal Yard are entering Jingshi and nearby areas in a steady stream.

Ordinary people with poor families are provided with coal stoves and briquettes free of charge.

And those wealthy families and rich officials need to buy honeycomb coal, and the price of honeycomb coal is almost half cheaper than charcoal.

Nevertheless, because of the huge demand, after a winter passes, it will certainly add a considerable amount of revenue to the treasury.

Three days later

Yuhuatian took Song Yingxing to the Qianqing Palace, asked Song Yingxing to wait outside the door for a while, and Yuhuatian went to see Zhu Youzhen first.

And Zhu Youzhen was planning another reform at this time, and suddenly a little eunuch came to report:

"Your Majesty, Yuhuatian, the superintendent of the West Factory, asks to see you."

"Calling"

Hearing Yuhuatian's request to see him, Zhu Youzhen immediately let him in.

Yu Huatian entered the room and bowed:

"Slave maid Yuhuatian, see Your Majesty."

Looking at Yuhuatian's dusty face, Zhu Youzhen asked:

"Did you find someone?"

Yuhuatian hurriedly replied:

"Back to Your Majesty, Song Yingxing is already waiting outside.

"Quick, let him come to me."

"Obey"

Yu Huatian immediately exited the room and went to pass Song Yingxing to see him.

This Song Yingxing is not an ordinary character, he must be introduced.

Song Yingxing (1587-1666), known as Chang Geng, was a native of Fengxin County, Nanchang Prefecture, Jiangxi Province (now Fengxin County, Jiangxi Province), and a famous scientist in the Ming Dynasty.

Throughout his life, Song Yingxing devoted himself to the scientific investigation and research of agriculture and handicraft production, and collected a wealth of scientific materials.

At the same time, his intellectual foresight made him a critical thinker of feudalism and the academic tradition of the Middle Ages.

Song Yingxing's writings and research areas cover different disciplines of natural sciences and humanities.

Among them, the most outstanding work, "Heavenly Creations", has been hailed as "the encyclopedia of Chinese craftsmanship in the 17th century".

Song Yingxing served as the prefect of Guangzhou during the Chongzhen period, and later resigned and returned to his hometown when he saw no hope.

Song Yingxing's main contribution is that he has summarized the knowledge of agricultural production and handicraft production that has appeared in China for thousands of years.

At the same time, the technical experience was summarized and systematized and organized, and then written into a book so that it could be handed down.

Song Yingxing's books include agriculture and handicrafts, such as machinery, bricks, ceramics, sulfur, candles, paper, weapons, gunpowder, textiles, dyeing, salt making, coal mining, oil extraction, and other production techniques.

In agriculture, Song Yingxing made a detailed record of the whole production process of rice soaking, breeding, seedling rolling, and grass cultivation.

He also pointed out various problems that deserve attention in rice cultivation.

In terms of handicrafts, Song Yingxing tries to use quantitative methods, and when he describes the production process, he pays special attention to the quantitative relationship between raw material consumption and finished product recovery.

In particular, the "Machinery" chapter describes in detail agricultural machinery and tools, including vertical shaft windmills, sugar carts, ox rope wheels, etc., which are of high scientific value.

Song Yingxing was the first scientist in the world to scientifically discuss zinc and copper-zinc alloys (brass).

He made it clear that zinc was a new metal and for the first time documented how it was smelted. This is one of the important achievements in the history of ancient metal smelting in China.

For a long time, China has become the only country in the world that can smelt zinc on a large scale.

Song Yingxing's method of refining brass with metal zinc instead of zinc compound (calamine).

It is the earliest record in human history of using copper and zinc to directly fuse two metals to obtain brass.

Don't say that there was no steel at the end of the Ming Dynasty, in fact, the end of the Ming Dynasty already had the most advanced steel smelting process in the world in the 17th century.

That was the iron-smelting process at the end of the Ming Dynasty. The steel production and quality of this process are the highest in the world for this era, at least 60 years ahead of the world.

It's a pity that many of his works that have been leading the world for many years have been burned by the Tartars, which is really unacceptable.

After seeing Zhu Youzhen, Song Yingxing immediately clasped his fists and saluted:

"Grass people Song Yingxing, see Your Majesty!"
