Time Travel: After Seizing the Throne, I Lead the Ming Dynasty to Take Off

“Pour the coal into the water…wash the coal??”

Hearing these words from Jinyiwei Captain Wu Yongliang, everyone present was completely bewildered. They only felt that these few simple words came out of Captain Wu's mouth, but when they heard them, they had no idea what they meant...

They know the uses of coal.

It is mostly used for smelting copper and iron weapons, firing ceramics, etc.

Something to burn.

Why are you throwing it into the water? Will it still burn?

Isn't this a waste of so many miners working day and night to dig and crush ore?

and also……

What the hell is coal washing?

This pitch-black thing, you still want to clean it? How is it possible?

Many questions suddenly appeared in everyone's mind, and everyone looked at the captain Wu Yongliang in front of them as if he were a fool.

Being stared at by everyone.

Wu Yongliang couldn't help but pursed his lips nervously, and even his back felt a little hot, with waves of uneasiness and guilt.

He was merely summoned by Song Zhong to do the work. He shared the doubts in these people's eyes, but he had orders to follow. Commander Song had specifically stated that this matter was personally ordered by His Majesty, and if he didn't handle it well, his entire family might be executed...

Thinking of this, Wu Yongliang forced himself to remain calm and shouted, "Get to work! What are you all looking at me for?!"

Everyone looked at each other in confusion, not daring to say anything. After all, this gentleman came from the capital, and the Jinyiwei token always made people tremble with fear.

But in the end, someone couldn't help but speak up.

"Captain Wu, this charcoal...it's for burning!"

"Nonsense! Do you think I'm a fool?" Wu Yongliang felt helpless, but in order to carry out the mission, he could only scold harshly.

"If the quality of this batch of coal is not as good as Captain Wu wants, all the efforts of so many people mining and sorting it out can be taken away by the blacksmith shop at the foot of the mountain. It won't be a waste of effort." Someone suggested cautiously, with a hint of heartache on his face.

"Pour it in!" Wu Yongliang deliberately put on a cold look, took out the Jinyiwei badge from his waist and showed it in front of everyone, "So my words are useless, right? Huh?" As he spoke, a hint of murderous intent appeared in his eyes.

no way.

The little ancestor in the palace has a request.

No matter how absurd the matter is, he has to go ahead with it.

The Jinyiwei were responsible for such unsavory work as monitoring officials and interrogating them about crimes.

Over the years, his eyes seemed to hold knives.

It immediately shut everyone up.

"Yes……"

"Yes, let's pour it in right away."

"Come on, come on, Captain Wu has spoken, it's time to get to work!"

"..."

Life was at stake, so the people below didn't dare to say anything more. After shouting a few times, they poured the raw coal they had brought in carts into the puddle one by one. For a moment, black smoke and dust filled the surface of the water.

This is more than just a puddle.

There are also some thick and long wooden beams around the puddle. The tops of the long wooden beams support each other to form a central intersection. Several pulleys are hung at the intersection. Several thick hemp ropes are hung on the pulleys. One end is held in the hands of several big men, and the other end is directly immersed in the water. No one knows what is hanging under the water.

These are simple equipment used for washing coal.

The principle of coal washing is to utilize the different physical properties of various components in the raw coal, use water as the medium, and jig and stratify the various components during the flow of the medium to screen out the ash, part of the sulfur, gangue, etc.

The higher the quality of the coal, the lower its density, so it will float to the upper layer of the water when the water medium flows.

Waste materials in coal, such as coal gangue, are much denser than clean coal and will sink to the bottom of the water faster.
