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

"That's easy to say."

"We just talked about this. If an epidemic breaks out, it can affect a village, a city, or even a prefecture or a province. If it's a cold or an injury, the body may decay and become devastated and die. I'm sure Fifth Uncle has heard and seen a lot of this." Zhu Yunhuan said.

Zhu Su nodded blankly: "I have seen it, but there is nothing I can do."

Zhu Yunhuan continued, "Now that we have the concepts of microscopic life and microorganisms, Uncle Wu can imagine how those microorganisms, so tiny they are completely invisible, can invade the body through the mouth, nose, and wounds. Unseen and impossible to remove, they can continue to harm the body, eventually causing decay and decay... Do those seemingly unreasonable symptoms now have a reasonable explanation?"

After hearing what Zhu Yunhuan said, Zhu Su was already stunned and stood there with his eyes wide open.

Before he could react.

Zhu Yunhuan continued to explain:

"Healthy people can catch typhoid fever from contact with someone who has it, sometimes even just by seeing each other without physical contact, because these harmful microorganisms float from one person to another in the air like dust."

"This principle applies to everything from typhoid fever to plague. In other words, the microbes that cause plague symptoms are more easily transferred than ordinary microbes, so their effects are as fierce and unstoppable as wolves and tigers."

"If we use existing medical theories to correspond to this."

"You let the sick pass on their disease to others, and those infected with the plague spread the disease."

Zhu Yunhuan first explained it using microscopic concepts, and then found similar statements in traditional Chinese medicine for analogy.

When Zhu Yunhuan finished speaking, he stopped talking.

The entire Qianqing Palace suddenly fell into a dead silence. Zhu Su felt as if all the sounds around him were moving away from him, and he could almost hear the sound of his own heart beating.

After a long while, he took a deep breath and sighed, "That makes sense!"

He seemed to realize something and immediately covered his mouth and nose with his hands, a look of panic on his face. "That void... seems pure and clear, but are there microorganisms like those in the soil and water?"

All of a sudden, he felt like there were invisible bugs everywhere and nowhere was unsafe. He held his breath as he spoke.

Zhu Yunhuan smiled calmly, "Fifth Uncle is very insightful, but there's no need to be so alarmed. Microorganisms are divided into those that are harmful and those that are not. If everything were unsafe, wouldn't humanity have ceased to exist long ago?"

Zhu Su also reacted immediately.

He lowered the sleeves that covered his mouth and nose and smiled awkwardly: "Hehe, it seems... that's the truth."

Now, the concept has been introduced.

Zhu Yunhuan didn't hold back and asked directly, "Now that we know the reason, if we can find a way to deal with these harmful microorganisms, wouldn't typhoid fever, incurable diseases, and epidemics...be easily solved? Fifth uncle, could this...be considered a method to prolong life?"

"Uncle Wu, may I ask if this... can be called a method of prolonging life?"

When Zhu Yunhuan brought the conversation back to the real topic, his last words sounded like a thunderclap in Zhu Su's ears!

Zhu Su was stunned for a moment.

Then, his face lit up with ecstasy, eager to try, and he excitedly exclaimed, "If it could easily cure typhoid fever, rotten wounds, or even a ferocious plague... it could be called a method to prolong life!"

He had to admit.

From beginning to end, every statement was well-reasoned and impeccable, and he couldn't find any flaws or defects.

He has been studying medicine for some years.

I know that most of the time, the most common way for patients to die is due to untreated typhoid fever.

And every time a plague broke out, large numbers of people died.

If this method is feasible.
