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

Just as Zhu Su was muttering in his heart, he heard Zhu Yunhuan directly ask: "Fifth Uncle, do you have anything else to say?"

Zhu Su's heart skipped a beat.

He forced himself to remain calm and said, "This is the purpose of my audience today."

"As for what Your Majesty has mentioned about organizing and collecting medical prescriptions and establishing and promoting a medical system within the Ming Dynasty, it will be a time-consuming task. My doctors, imperial physicians, and the Imperial Hospital are currently deliberating on this matter."

"Now that this matter is settled, I will take my leave."

Zhu Su immediately took the opportunity to ask tentatively. He was not sure whether this kid had really revealed what had just happened. Of the thirty-six strategies, running away was the best one.

But he felt that he might not be able to escape.

The imperial power is above all else; all under heaven belongs to the king, and all within the four seas are his subjects.

however.

Zhu Yunhuan just waved his hand casually: "Go."

Zhu Su was stunned for a moment, then felt a sense of relief and then ecstasy. He immediately bowed and said, "I will take my leave!"

After saying that, he took a few steps back and hurried out of the Qianqing Palace.

Seeing Zhu Su running away in fear, Zhu Yunhuan shook his head and smiled helplessly, muttering to himself: "Fifth Uncle is too cautious. Am I really that cruel?"

But he also understood Zhu Su's thoughts.

After all, as soon as he ascended the throne, he issued an edict prohibiting the princes from entering the capital. Smart people could see that he was wary of the princes and even wanted to trick them. But Zhu Su was called to Yingtian Prefecture at such a sensitive time.

It’s no wonder that Zhu Su was nervous.

Moreover, he had just proposed a theory and asked Zhu Su to investigate and verify it. After Zhu Su had finally finished the paper, he was told that it could not be published. Even a clay man would still be angry... It was indeed easy for Zhu Su to misunderstand that he was setting up a trap.

Think of this.

Zhu Yunhuan lowered his head again to look at the "paper" on the dragon desk and the optical microscope drawing next to the paper. With a faint smile on his face, he raised his eyebrows thoughtfully.

"This is indeed a great article. Now the first lens has been hand-ground. Although the magnification should only be a dozen times, I can skip the creation process from ordinary microscopes to modern microscopes!"

The magnification of an optical microscope.

It is the result of multiplying the magnifications of the objective lens and the eyepiece.

Next, you just need to make a mold with the convex lens in your hand, and it will become much easier to make a convex lens of the same magnification.

As long as you have two lenses with sufficient magnification, and ask the Ministry of Industry or the Industrial Department to make the other parts of the microscope, the first microscope of the Ming Dynasty will be ready.

Even if both lenses only have a magnification of more than ten times, multiplying them by two, this microscope can have a magnification of more than one hundred to more than two hundred times.

"With the advent of the microscope, antibiotics became available."

"Who says that human life span is fixed? Who says that life span cannot be extended?"

Zhu Yunhuan chuckled, tapping the table subconsciously with his fingertips, a look of determination flashing in his eyes.

"The rest depends on the cheap cloth produced by the Industrial Department and the Ministry of Industry, and the washing out of anthracite."

Zhu Yunhuan was secretly plotting in his heart.

He pondered for a moment.

He looked at the lanterns hanging on the corridor outside the hall swaying in the wind and sighed softly: "The weather is getting colder and colder..."

……

the other side.

On the way back to the medical hospital from the Qianqing Palace, Zhu Su walked for a long time before he felt relieved and breathed a sigh of relief.

“Huh…Huh…I thought I was going to die here!”

"But he was so wary of the vassal king, and I revealed such a huge flaw, but he really just ignored it? Did I misunderstand him? Or does he have other plans?"

"This article of mine will be useful sooner or later..." Zhu Su walked quickly towards the medical hospital, muttering in a voice that only he could hear, with a look of disbelief on his face.
