Daming: I, Yang Xian, really govern Yang!

Chapter 141 Modern Scientific Experiments
Yangzhou.

In this era, all skilled craftsmen are absolutely reliable in their craftsmanship.

But they all have one common problem, that is, they don’t know much about literacy.

Yang Xian set up an adult school in Yangzhou, where he hired people to teach his craftsmen how to read.

Because modern experimental theory cannot be separated from the most basic cultural knowledge as a basis.

It may be difficult for the older generation to change, and those in Yangzhou Primary School are still too young.

Yang Xian only hopes to cultivate some real scientific talents among the younger generation, not just machines that follow his orders step by step.

What Yang Xian has to do is to teach them modern scientific experimental methods with his own practical actions.

glass factory.

Bags filled with sand were numbered with charcoal on the outside, from 1 to 7.

Each number represents the sand from a different region.

Yang Xian asked the workers to clear out an open space, and then spread straw mats on the open space, and then spread snow-white sheets on the straw mats.

Then Yang Xian asked the workers to pour the sand representing their respective numbers onto the straw mat in front of them.

Finally, I took out a special fine-toothed bamboo rake.

"Sir, is this?"

Master Jin saw the magical fine-toothed bamboo rake in front of him, with a puzzled look on his face, and he couldn't help but ask.

I saw a mysterious, dark, long and thin stone tied to the rake teeth of each rake.

He didn't know what this thing had to do with firing colored glaze.

Yang Xian smiled and said, "Do you know why the glass you make is mixed with various colors?"

Master Jin shook his head.

This has been the case since ancient times. He only knew that the colors of the colored glaze fired from sand in different regions were different.

Some are green, some are yellow, and some are red
All they can do is write down the colors that can be produced from their respective sand and gravel mines.

Yang Xian said: "That's because there are impurities in the sand, and iron is the main component. The special fine-toothed bamboo rake in my hand is used to remove iron."

Yang Xian said and started to demonstrate.

I saw him holding a special fine-toothed bamboo rake in his hand, and began to plow the white sand on one of the straw mats in front of him.

Master Jin watched Yang Xian's movements, his attention gradually shifted from him to the special fine-toothed bamboo rake, and then he saw an unexpected picture.

Master Jin rubbed his eyes with an incredible look in his eyes.

He stepped forward, squatted down in front of the straw mat, and looked carefully. He saw that as Yang Xian plowed the sand over and over again, some black and brown powder in the white sand were constantly being removed by the piece tied to the special fine-toothed bamboo rake. A dark, slender stone was sucked out.

"Sir, is this dark stone a magnet?" Master Jin couldn't help but ask.

Yang Xian nodded, smiled and said: "Since we know that the reason why the glass is mixed with mixed colors is because of impurities, mainly iron, then what we have to do is to remove the impurities. Use this special fine-toothed bamboo rake The process of plowing sand is to remove iron from quartz sand.”

"Old Jin."

"The little guy is here."

"Next, I will hand over this task to you. Use the method I just used to remove iron from the sand one by one, then put it into the glass for firing, and keep a record. What we have to do now is Find out where the quartz sand produced is most suitable for making transparent glass." Yang Xian said.

It’s not just these seven bags of sand that need experimenting.

Next, there will be a steady stream of sand from all over the country sent to Yangzhou.What Yang Xian has to do is to find the optimal solution based on the current conditions.

In Yangzhou, everything is progressing in an orderly manner.

On this day, Yang Xian received a letter from Li Jin.

In addition to greeting Yang Xian, the content of the letter focused on the current situation of the Hu family and his daughter in Dingyuan County, talked about Hu Yeer's admiration for Yang Xian, and talked about their hardships in fetching water.Li Jin asked Yang Xian in the letter if there was any way he could help the father and daughter.

"In this matter, if there is anyone in the world who can really help them, the only one I can think of is Mr. Yang."

“Student Li Jin, here’s to Jin An.”

Yang Xian put down the letter in his hand.

After thinking about it seriously, it was difficult to get water, so a water tanker would be enough.

The waterwheel first appeared during the Three Kingdoms period in my country and was invented and manufactured by the Wei people.

Later, in the Tang and Song Dynasties, waterwheels had developed to the point where they could use water power as power to make a cylinder wheel, which could be used with a pool and a connecting cylinder to deliver low water and high water.

By the Ming Dynasty, waterwheel technology had become very mature.

But the biggest difficulty now is that, according to Li Jinxin's description, the place to collect water is at the foot of the mountain, but the fields for cultivation are on the mountain.

At such a high distance, even if a waterwheel was built, it would be very laborious to collect water.

Yang Xian already has an idea in his mind, but he still needs to conduct an on-site inspection before doing so.

But before that, the rail train must at least be built in Dingyuan County, Fengyang Prefecture.

Although as the merit points continued to nourish and transform Yang Xian's body, Yang Xian found that his vision, hearing, memory, and various reflexes had reached an extremely terrifying level.

Not talking about various fighting skills, if it was just pure hand-to-hand combat, he thought no one would be his opponent now.

When he first got the transformation the year before last, he thought he could only defeat five Wang Yuemin at one time. Now he thought that it would not be a problem at all for him to defeat five Lan Yu at one time.And it’s the kind that doesn’t take too much effort.

Of course, this is without talking about various fighting skills and the premise of not using weapons.At this point, the battle-hardened Lan Yu is naturally not comparable to Yang Xian.

But no matter how hard you fight, you are still a human being after all.

Therefore, Yang Xian thinks that it is better for him to be more cautious when going out now.

Beijing.

The imperial palace, the Hall of Supreme Harmony.

"Completely abolish corvee?" Zhu Yuanzhang suspected that his ears had heard wrongly.

You must know that corvee has existed for thousands of years from ancient times to the present, and it has been this way in all dynasties.

But now Zhu Biao suddenly said that he would completely abolish corvee service. How could this not shock Zhu Yuanzhang?

"Yes, Father, you heard me right, that is to completely abolish corvee." Zhu Biao nodded firmly.

Then he talked about Yang Xian and what he said about the dangers of corvee labor, and how the court needed to hire workers after the abolition of corvee labor, and share the labor service with the farmers.

The more Zhu Yuanzhang listened, the more frightened he became, and the more he listened, the more excited he became.

Because Yang Xian said that the reason for the short life span of various dynasties and generations was largely due to corvee service.

And now if the Ming Dynasty completely abolishes corvee service, does it mean that the Ming Dynasty can last for thousands of generations?
You can count many shortcomings of Emperor Hongwu.

But there is one thing he lacks the most.

That is courage!
