Daming: Grandpa Emperor, please get up and sit on my throne!

This process naturally has mature industrial operation methods in modern times, but in this era of simple conditions, only some simple jigging can be carried out.

Although it can't be that precise.

But it is still possible to achieve the level of usability.

"Captain Wu, they've all... fallen in."

After the first batch of coal was poured into the water, everyone stepped aside and reported the situation.

His face was filled with confusion, puzzlement, regret and many other emotions.

Wu Yongliang pondered for a moment.

His eyes fixed, and then he looked at the muscular young men who were holding the other end of the hemp rope beside the puddle, and nodded: "Let's start."

After saying that, he stared at the water nervously.

As his words fell.

Several muscular men immediately pulled the thick hemp rope in their hands. Driven by the pulley, the heavy object sunk in the water at the other end of the hemp rope slowly rose up, and the water surface floated, as if it was about to boil.

These devices are used to stir the water in the puddle.

Once the water is stirred, the raw coal inside will naturally be driven to roll while flowing as a medium of water, and then stratify itself under the action of gravity.

"One, two, pull!"

"One, two, release!"

"One, two, pull!"

"One, two, release!"

Several young men had veins bulging on their foreheads. They shouted slogans and kept pulling the thick hemp rope back and forth.

The water in the puddle was constantly stirred.

The raw coal that had been dumped into the water was swirling and surging in it, floating up and down...

After stirring it for a while.

Then the voice of Captain Wu Yongliang was heard again: "Almost done, start fishing!"

The words fell.

The miners who had been waiting nearby since early morning immediately followed Wu Yongliang's instructions. They picked up the bamboo baskets in their hands and threw them into the water as if they were drawing water from a well, and then used ropes to pull the bamboo baskets to the shore.

It’s different from fetching water.

The water in the bamboo basket will leak out, and what is blown up is the clean coal carried to the upper layer by the water flow, which is the so-called anthracite.

In this era, human resources are the least valuable.

With the actions of many miners, the coal that had been submerged in water and then fished out again soon piled up into a small hill.

This batch of coal salvaged was visibly purer, pitch black, without any stones, ash or other things.

However, no one understood what this meant at the moment.

To everyone, the pile of stuff was still the same pile of stuff, it just had been in the water and seemed to have become wetter and darker.

"Take out some and dry it over a fire."

Wu Yongliang swallowed nervously and began to process the wet coal according to the processing procedures given by Zhu Yunhuan in advance.

He reviewed it in his mind, making sure he hadn't missed any steps.

Then, I began to think: If what Your Majesty said could really be realized, then after this batch of coal is dried (baked), it will become anthracite...

The title of Jinyiwei was very effective. Even if there were doubts, no one dared to refute it.

The miners present immediately did so.

As someone started to light a fire and heat the coals.

The scene fell into silence, with only the roar of the waterfall nearby and the occasional crackling of firewood as the only sounds.

Everyone, including Wu Yongliang, stared at the part where the test sample of coal was taken out for drying, nervously and curiously.

Throw the coal into the water, stir it, then take it out and dry it...

Think about it, this is not something a decent person would do. It is even more outrageous and ridiculous than a three-year-old child peeing and playing in the mud. But the imperial court actually sent a captain of the Jinyiwei to this mountain to do this. It is even more outrageous. It is outrageous to the extreme.

But it's already been done.

Naturally they wanted to see it.
