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

"Logically speaking, there really is no answer."

"I'd like to see what this young emperor has to say."

While thinking.

They saw Ma Sanbao, the most favored eunuch beside the emperor, had walked to an antique display stand not far behind Zhu Yunhuan's couch.

This display cabinet is not only filled with exquisite and beautiful antiques, porcelain, jade, etc., but more unusually, there is a board hanging on it with some strange words, contents, and symbols written on it.

They did recognize a few of the words on it.

But as for other contents and symbols, I had no idea about them and had never seen them before.

The chief eunuch Ma Sanbao skillfully turned the board over, and on the back of the board... was an even stranger... painting?

at the same time.

They also saw that the young emperor, who had been lying lazily on the couch, slowly stood up and walked towards the board.

Zhu Yunhuan stood in front of the board.

He tapped the blackboard habitually: "Look here, the excessive amount of Ming Dynasty treasure notes has caused prices to rise in the country, resulting in the shrinking of wealth in the hands of the people. This is the reason."

And when Zhu Yunhuan finished speaking.

Yu Xin, Gu Pu, Xia Yuanji and Lin Chengxuan all stared at the picture that Zhu Yunhuan's bony hand was pointing at, as if they had discussed it beforehand.

Frowning.

And their expressions seemed to say: That's it? A painting, something that can't even be called a painting... What the hell is this?

This is a picture that they don't understand.

There are some horizontal lines, vertical lines, and curved lines intertwined with each other on it. In addition, there are also some symbols that they cannot recognize.

There are a few words they can recognize.

They are: "value of money", "price level", "amount of money", "money supply curve", "money demand curve", "equilibrium value of money", "equilibrium price level"...

However, even in this "painting", there were a few words that they could recognize, but that was only limited to the level of "recognizing the words". As for what these words meant when put together... they had no idea what they meant.

This is the picture Zhu Yunhuan gave them.

In fact, it is the "relationship diagram of money supply and money demand determining monetary balance" in the later "Macroeconomics".

Currency, prices, inflation…that kind of stuff.

Zhu Yunhuan once talked to Ma Sanbao in front of Zhu's coffin about some simple and plain truths, using his "low-cost mass production of glass" as an excuse.

But that just gave Ma Sanbao a rough idea.

And real economics.

But it is an extremely complicated thing.

Because it attempts to integrate all economic activities of a country into a system, making it visible, predictable and calculable.

If we want to truly achieve the level of being able to regulate the entire national economy, it is not practical to just talk about some glass.

The four people in front of him were the ones specially selected by Zhu Yunhuan to be responsible for the country's economy, banking system construction, and macro-control in the future.

Of course Zhu Yunhuan wanted them to learn thoroughly.

Yu Xin and others stared at the picture that Zhu Yunhuan pointed at for a long time.

"This... a painting... is a bit confusing, with all the horizontal and vertical lines..."

"This thing..."

"How could it possibly be the answer to the question His Majesty asked?"

"Forgive my humble opinion, I cannot understand your Majesty's deep meaning."

"..."

To them, it was like reading a book written in heaven. Naturally, they all shook their heads and gave up.

At the same time, I felt funny.

"A tangle of lines, a jumble of symbols... Seeing your Majesty's incredibly serious and solemn expression just now, I honestly thought you had the ability to explain something so complex."

"Ridiculous! What on earth was I expecting? Is this another one of His Majesty's new tricks?"

"Forget it, forget it. The current young emperor is notorious for his eccentricity and cynicism. Don't overthink anything else. Just be careful with your words and actions. Don't displease His Majesty and bring yourself into trouble."

"..."

On the surface, several people spoke carefully and acted cautiously, but they had already started to secretly complain in their hearts.

Zhu Yunhuan certainly could not hear their voices.

However, he had seen this kind of scene many times before, and he knew exactly what the other party was thinking!

Of course, when Zhu Yunhuan heard the people in front of him describe his classic economics coordinate chart as "horizontal lines, vertical lines, and incomprehensible paintings".

Zhu Yunhuan suddenly realized a problem.

Damn! There's no such thing as a "coordinate system" yet... It was invented in 1637 by French mathematician and philosopher René Descartes, who combined geometry and algebra to create analytic geometry...

Calculate the time.

It’s still more than two hundred years too early!

Zhu Yunxun sighed softly and complained in his heart: "My head hurts. Opening up new land is so difficult!"

However, he had encountered this kind of conceptual and cognitive problem many times before.

At least I'm familiar with the route.

No problem, the invention is great, I'll own it next second. (This is a rhyming pun, but I'm sorry, it's mine next second.)

After a pause, Zhu Yunhuan explained calmly, "This is a data representation method. You can call it the Kaiqian coordinate system."
