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

Therefore, Zhu Yunhuan did not look at it too closely.

Zhu Chaofang nodded: "I understand."

"Among the nobles, there are two types: the Huaixi faction headed by Lan Yu and the other nobles. However, among the nobles not affiliated with Lan Yu, the families of Duke Wei and Duke Xin are the most suitable. Excluding these two, there is the faction headed by Lan Yu and the influence of the civil officials in the court."

"I'll make arrangements for the draft day."

"Standing in the front will be the two girls from the Duke of Wei and the Duke of Xin. Lan Yu's adopted daughter was brought into the palace to meet you once, so you should know her. There's no need to arrange anything else. As for the others, I'll place the 'ladies' with military backgrounds on the left, and the 'ladies' with civil service backgrounds on the right. You can choose as you see fit."

Zhu Chaofang thought about it for a while and made arrangements.

After all, this process still has to be followed. If Zhu Yunhuan's name is crossed out from the booklet without even meeting him, it would seem too unfair and too deliberate.

"Then let's arrange it this way." Zhu Yunxun said.

"Yes, we are still in the mourning period for the emperor, so the Ministry of Rites and the Imperial Observatory need to discuss the time together." Zhu Chaofang said.

Zhu Yunhuan nodded, nonchalantly saying, "You guys decide, time isn't important." After all, he could dance repeatedly on Old Zhu's grave, so naturally he had no taboos or particulars.

"Yes, I will retire."

Zhu Chaofang glanced at the memorial on Zhu Yunhuan's desk, a look of heartache in his eyes, but he also knew that this was something that an emperor had to face.

All she could do was give her full support, so she didn't bother him too much and left the Qianqing Palace after discussing the matter.

After Zhu Chaofang left.

Zhu Yunhuan couldn't help but glance at the memorials on the dragon desk, frowned slightly and complained: "This pile of junk is really endless."

But there was no other way around it. Zhu Yuanzhang abolished the position of prime minister, and all matters, big and small, came before the emperor, so naturally there were a lot of memorials.

Zhu Yunhuan complained.

But he still picked up the imperial calligraphy and started to deal with it.

The burden of the entire Ming Dynasty fell on his heads, and these memorials and state affairs were the basic foundation of the Ming Dynasty. If these trivial matters were not handled well, things like the Industrial Revolution and going into business would all be castles in the air.

All he can do is to consolidate the power in his hands as quickly as possible.

Only in this way will we have the capital and confidence to establish a cabinet.

Then I can free up my hands.

……

Silent all night.

The next day, after the morning court session, Zhu Yunhuan returned to the Qianqing Palace.

No new memorials had been submitted to the Dragon Desk yet, and Zhu Yunhuan took out a drawing with a strange-shaped pattern on it.

However, this pattern is definitely not unfamiliar to people in later generations - optical microscope.

The principle and structure of a microscope are not complicated.

As a top science student, I was very familiar with it - the tube with the eyepiece, the arm, the converter, the objective lenses of different magnifications, the stage, the aperture, the shutter, the reflector...

These things have been carefully outlined on the drawings.

If you want to make these parts, either the Ministry of Industry or the Industrial Department can make them. The difficulty lies in grinding the lenses - grinding the glass to a certain magnification - this is a delicate job that requires constant trial and debugging.

Even though he used the microscope many times.

You can ask him to grind convex lens glass.

We can only take it slowly.

Although with his status, he can get a lot of people to help grind with just one order.

But this involves the scarcity of "glass".

If he took out a large pile of glass and asked a large number of people to grind the magnifying glasses, the glass would become broken and the scam of deceiving the Huaixi nobles would be broken.

So he and Ma Sanbao had to grind it by hand.

Zhu Yunhuan put the microscope drawing aside and took out a piece of glass whose surface was not particularly smooth and transparent, but was thin on the outside and had convex sides in the middle.

This is the semi-finished product he had polished halfway before.

"Success or failure depends on this one move!"

Zhu Yunhuan took a deep breath, applied extremely fine friction material on the surface of the glass, and then rubbed it carefully with a silk handkerchief dipped in water.

A very subtle rubbing sound was heard in the Qianqing Palace.

Zhu Yunhuan rubbed it carefully.

I don’t know how much time passed.

When he washed the convex lens in the basin, the surface became extremely smooth, and the entire piece of glass was completely transparent...

When you hold this convex lens in your hand.

Zhu Yunhuan's heart moved, and he suddenly became a little nervous, with a vague feeling that he was going to succeed.

He couldn't wait to dry it completely.

Then he looked at the drawing on the table with a microscope on it.

The image that appeared in his eyes was exactly a corner of the drawing, and it was estimated with the naked eye that the magnification was ten to twenty times!

"Out!"

Zhu Yunhuan's heart began to beat wildly.

The first driver used a magnifying glass with a magnification of approximately this magnitude.

Although it's just the beginning.

But the subsequent things will obviously be much easier, and you will gain a lot more experience, after all, you have gone through a long process of trial and error before.

"Ten to twenty times the amount has been achieved."

"Then it will be forty times, eighty times, a hundred times."

"By superimposing and multiplying the eyepiece and the objective lens, it will be easy to make the optical microscope of the previous life." Zhu Yunhuan muttered to himself with an excited smile on his face, looking at the convex lens in his hand.

At this moment, the young eunuch outside the door slowly walked in: "Your Majesty, Princess Jiangdu requests an audience."

Zhu Yunhuan temporarily put the convex lens in his sleeve. Although he also trusted Zhu Chaofang, it was his consistent principle to do things in secrecy.

"Speak." Zhu Yunxun said.

But he was slightly worried in his heart.

Logically, there should be no other objections to the selection of a concubine, and Zhu Chaofang should be busy making arrangements now.

Zhu Chaofang walked in quickly.

With a hint of hesitation on his face, he said, "Your Majesty."

"Early this morning, the Duke of Wei's Mansion sent a message saying that Xu Miaojin suddenly fell ill and might not be able to participate in the selection of concubines." Zhu Chaofang said anxiously.
