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

"Fifth Uncle, retreat."

"You're meddling a little too much."

There was a hint of majesty in Zhu Yunhuan's voice that brooked no room for questioning.

As the words fell.

He had already pushed aside the water cup, soil and other debris on the dragon desk, picked up a memorial from the desk, opened it, and began to read it.

It was obvious that she had no intention of listening to him say another word.

He was clearly just quietly reading the memorials, and one could even see a hint of childishness on his handsome face.

But it gives people an inexplicable sense of oppression.

Zhu Su was slightly startled, pursed his lips and swallowed the words that were about to come out of his mouth, secretly regretting that he had opened his mouth.

What he had just seen and heard was so novel, and he had been entrusted with such great responsibility and trust by Zhu Yunhuan that he lost his composure for a moment.

Looking at the young man who was reviewing memorials with an indifferent expression on the dragon desk, he suddenly remembered that even though this young man was his nephew and someone with whom he could discuss trivial matters, before all these attributes, he was first and foremost an emperor!

Cruel and extremely powerful!

Now the other party really has no intention of touching me, but instead seems to want to use me.

But what if one day I have the intention to overstep my authority?

Zhu Su had no doubt at all.

His nephew would immediately put the knife to his neck.

After a pause, Zhu Su said, "It is my humble servant's fault for being reckless. I will take my leave."

But he just took a few steps back.

Then he heard Zhu Yunhuan's voice reminding him: "Fifth uncle, I forgot the microscope. Also, I don't want anyone else to know about this except those related to it."

Zhu Su's heart skipped a beat.

He hurriedly stepped forward to take the microscope that Ma Sanbao had handed him, responded, and then left the Qianqing Palace with a heavy heart.

Zhu Yunhuan wrote "Read" on the memorial in his hand and closed it.

He glanced at the place where Zhu Su disappeared at the door with great interest, and smiled faintly with satisfaction: "It seems that my fifth uncle is very considerate."

Ma Sanbao, while tidying up the debris on the dragon desk, echoed softly, "Your Majesty is the Son of Heaven, with great power and vast knowledge. You know things that ordinary people don't know and see things that ordinary people dare not imagine. Who dares not to respect you?"

After hearing Ma Sanbao's compliment, Zhu Yunhuan casually picked up the convex lens that had been placed on the table and asked thoughtfully, "What about those prisoners I asked you to bring up in prison?"

Just as Zhu Su desired.

Zhu Yunhuan also wanted to get a more sophisticated and higher magnification microscope.

Fortunately, he already had a template for the convex lens, so this thing was no longer a castle in the air that people of this era had no idea about. As long as someone could understand the related principles of glass, refractive index, focal length..., people of this era could continue to grind out a larger magnification.

Zhu Yunhuan no longer had to worry about this matter.

Zhu Yuanzhang was a strict ruler. In addition to ordinary criminals, there were also high-ranking officials with good knowledge in the prison.

"Return to Your Majesty."

"I have nominated twenty people who have committed serious crimes and circulated your Majesty's theory to them for study. Two of them can understand your Majesty's intention." Ma Sanbao replied.

Zhu Yunhuan was not surprised by this. After all, people who were called "learned" in this era mainly studied Confucianism, and not many of them could quickly accept and understand physics and mathematics.

He raised his eyebrows and said nonchalantly, "Keep them under secret custody and let these two men grind the glass. The others can be dealt with. If we don't have enough manpower, we can just try with some more prisoners." He needed to keep it a secret.

That's why the prisoners are taken.

Even though he had absolute power over life and death, he would not execute an innocent person simply because the person had seen something that could not be spoken of.

After handing this matter over.

Zhu Yunhuan continued to review the memorials without taking it seriously.
