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

"The principle of coal washing is actually not that complicated..."

Zhu Yunhuan raised his eyebrows and wrote down the three words "Industrial Department" after the second question - at this time, only "strange skills and tricks" could be relied upon.

The members of the Industrial Department were originally descendants of Wang Zhen and his team of craftsmen.

They were good at agronomy and also good at designing and manufacturing machinery. They had even invented a water-powered spinning machine that was hundreds of years ahead of its time...

Just let them understand the principle of simple coal washing.

If we let them apply their knowledge and talents in mechanical transmission, mechanical design and manufacturing, why can't they come up with something like a "hydraulic coal washer"?

It just so happens that the spinning work of the Industrial Department is almost finished.

Even if it is necessary to continue producing yarn, it only needs to be supervised by someone who is familiar with the operation of the water-powered spinning machine, and there is no need for the head of the family, Wang Yingxin, to do it personally.

Think of this.

Zhu Yunhuan immediately looked up at the gate and said, "Someone come."

"Yes, Your Majesty, I'm here." The eunuch in charge of staying outside immediately walked in and responded.

"Go to the Industry Department... No, he's currently at the Royal Manor outside the palace. Go there and convey my order, asking Wang Yingxin to come to see me at the Qianqing Palace."

Zhu Yunhuan immediately gave an oral order to summon the person over.

"Yes, Your Majesty."

The eunuch replied and was about to leave to pass on the imperial edict when he was stopped by Zhu Yunhuan: "Wait, I have other things to do in the morning. Ask him to wait until the afternoon and come to see me again."

"Yes." The eunuch replied and left the Qianqing Palace.

Zhu Yunhuan's gaze fell on his dragon desk again.

He asked Wang Yingxin to come back for an audience in the afternoon, not for any other reason, but because he was more anxious to deal with the third issue written on the paper - the transportation issue.

Current traffic.

It's nothing more than land transportation and water transport.

Even if the court's transportation channels were used, it would take at least one or two months to expedite the delivery of light goods such as cloth, not to mention things like anthracite that were heavy, bulky, and required a large transport volume - just like the idea of ​​transporting anthracite this time, it was a complete mess.

This is just the current situation.

In the future, we will have to develop the industrial revolution and the domestic production economy, which will require a lot of transportation. Otherwise, why would China in the 21st century become an infrastructure maniac? This is all due to demand.

And about this point about transportation.

Of course Zhu Yunhuan didn't even have to think about it: prepare for railway construction!

When it comes to railway construction, we are back to one of the most important materials - the Great Leap Forward in Steel Production.

When the eunuch who delivered the message closed the door.

Zhu Yunhuan also wrote the words "railway transportation" and "steel smelting" on the third question on the paper.

"Come here, go to the Alchemy Department. I want to see my elixir in person." Zhu Yunhuan put away the paper on the table and said loudly.

The idea of ​​the Great Steel Production Campaign was his from the very beginning.

Industrial Revolution.

Make weapons.

The basic material is indispensable.

However, steelmaking is not that easy, and there are more urgent things to do in the past two months, so the current progress is to build a brick furnace for making refractory bricks.

What to do next.

It is the refractory material high-alumina bauxite needed to burn refractory bricks, the high-burning temperature coke needed to produce high-quality steel, and the mining of iron ore.

In this era dominated by cold weapons, the mining of iron ore does not require special effort. As for coke, coal mining is now in full swing, and to obtain coke, one only needs to desulfurize and coke the mined coal.

The only remaining unresolved issue is the refractory material high-alumina bauxite.

The use of this thing has not been fully developed in this era, and there is not even any record of it.

Zhu Yunhuan had to start from scratch.

Fortunately, the Alchemy Bureau has been established now.

The alchemists who are tinkering with elixirs have the most mineral materials of all kinds, colors and properties.

Maybe we can find high-alumina bauxite directly through these alchemists.

Fortunately, Wang Yingxin still had to come from the royal manor outside the palace, which would take some time. Zhu Yunhuan simply went to the Alchemy Department to take care of this matter first, and gave them two lessons to further deepen the concepts of chemistry. It was also helpful to put these spare cattle and horses into use as soon as possible and start chemical and military development as soon as possible.

Following Zhu Yunhuan's order.

The Dragon Guard and the Tiger Guard naturally arranged for the imperial carriage immediately. Zhu Yunhuan, accompanied by his eunuchs and the Embroidered Uniform Guard, arrived at the Alchemy Department, which had just been established yesterday...

Inside the Alchemy Department.

The fifteen "alchemy immortals" personally selected by Zhu Yunhuan were of course not making elixirs at this moment.

People like Zhang Yuchu of the Zhengyi School and Ma Rui of the Quanzhen School have at least started the path of inner alchemy practice. Their minds are not entirely focused on refining these so-called external elixirs, so they still meditate and practice in their free time.

But there are many other alchemists.

But at this moment he looked extremely confused.

to be honest.

Just yesterday, their worldview collapsed.

Everything they had been striving for so long had become a complete joke. The essence of this world had become various so-called "elements." Their alchemy was nothing more than the transformation and combination of various elements. Not only would eating them not lead to immortality, but they would also...

Who the hell wouldn't be confused all of a sudden?

"His Majesty has arrived!" At this moment, a shrill voice came from outside.

This voice naturally immediately captured everyone's attention—who was the one who had shattered their worldviews and perspectives?—wasn't it the so-called "tyrant" who had brought them here?

"Your Majesty... Your Majesty?"

Everyone's eyes lit up immediately, and with a mixture of love and hate, as well as anticipation, they looked towards the Young Emperor who appeared at the door of the Alchemy Department...
