The group drove back to the county again, but they had an extra cart of sweet potatoes with them when they returned to the city.

When they arrived at Laoliu Restaurant, Zhang Laoliu was instantly stumped by the sweet potatoes.

I've never seen this thing, and I don't know how to make it.

Later, Fang Zhengyi personally taught me how to make some simple baked sweet potatoes, steamed sweet potatoes, and sweet potato porridge.

Finally, I made a plate of candied sweet potatoes myself.

A bunch of sweet potatoes had just been made and Fang Zhengyi tasted one. It was far less sweet and sticky than the advanced improved ones such as Yanshu No. 25.

So in order to ensure the publicity effect, a handful of white sugar was sprinkled into the sweet potato porridge.

When the food was served, everyone seemed a little impatient as they smelled the strange fragrance.

Smell this...Such a high-yield crop doesn't seem to taste that bad?

In order to ensure that everyone could eat it with confidence, Fang Zhengyi picked a small roasted sweet potato and ate it in two or three bites without even peeling the skin.

Seeing this, everyone felt relieved and started eating.

Fang Zhengyi attentively brought the candied sweet potatoes to Emperor Jing's table and performed a candied sweet potato show on the spot.

Emperor Jing was extremely satisfied after eating. Such high-quality and delicious food can be called perfect.

During the dinner, many people showed their goodwill to Fang Zhengyi.

Are you kidding? With such a great achievement... no one would dare to say anything to Fang Zheng even if he spent the rest of his life lying in the imperial court.

What's more, he was already favored by the emperor, and now he is even more prosperous than before!

...........

The next morning, Emperor Jing and all the officials prepared to return to the capital.

Fang Zhengyi asked for two days off and took Li Yuanzhao and the princess with him. Emperor Jing readily agreed and left a group of guards.

When Emperor Jing came to see him off, he patted Fang Zhengyi on the shoulder and said, "Fang Qing... remember to bring the prince and princess back soon. I will also give you a great reward!"

Fang Zheng smiled and said modestly, "How dare I ask for any reward! I am only doing what I should do for Your Majesty."

"Okay! Then I won't give it to you!"

"............, Your Majesty is really a joker."

"Hahahahaha, okay, I'm leaving. Remember to take the prince with you to watch and learn more."

After saying this, Emperor Jing got into the car and drove away.

Fang Zheng kept sucking his teeth as he watched the carriage going further and further away.

Your Majesty is too cunning, you must be careful when fooling others in the future!

When Li Yuanzhao saw the emperor leave, he immediately shouted, "Old Fang! I want to watch Legend of Jigong!"

Fang Zheng glanced at him and said disdainfully, "What's so good about that thing? There are some good things in the county government office. I'll take you to have a look later."

"I'll walk with the princess first!"

Li Yuanzhao immediately bared his teeth and said, "I'll go too!"

Fang Zheng had no choice but to accompany the princess to the women's clinic with his burden.

The original purpose was to bring Li Miaohan to the county's women's clinic for a checkup. Ordinary clinics do not have the habit of keeping analysis files.

However, under Fang Zhengyi's order, the county's medical clinic has established a rough filing system for the patients.

The ancients were too ashamed to talk about some gynecological diseases, which caused them to waste their lives in vain.

In masterpieces like Compendium of Materia Medica, Li Shizhen also warned men to stay away from women during their menstrual period so as not to weaken their yang energy.

There are some things that are inconvenient for Fangzheng Yi to do in Taoyuan County. Not only will they be criticized, but they are also difficult to push forward. After all, it is a fight against the backward ideas of the whole society, and it is extremely difficult to accomplish anything.

However, the potential future profit space for sanitary napkins is very large, and if it is successful, it will be a win-win situation. Having a strong backing like Princess is perfect.

I was worried that she was too young to handle the pressure, so I sent her to the women's clinic to help her strengthen her advanced concepts and learn some knowledge.

After sending her to the women's clinic, Fang Zhengyi felt it was not convenient for him to stay any longer, so he just told a few guards to look after the princess and then went to the county government office with his burden.

Li Yuanzhao kept shouting along the way that he wanted to see some good things.

Fang Zheng sneered in his heart, what a good deal, isn’t it? When I see you later, your three views will be shattered!

................

In the county government office, Li Yuanzhao looked at the device in front of him that looked somewhat like a telescope with a confused look on his face.

Pointing at it, he asked, “What is this?”

Fang Zhengyi sighed: "This is called a microscope."

I just learned from communicating with Ao Chen that the microscope has already reached its third generation.

The two microscopes he had brought back earlier were very blurry. Fang Zheng felt that they were useless and unconvincing, so he just threw them home to collect dust.

He has tried this third generation twice and it is much clearer than before, and he can clearly see the cells.

It can be said that it has great practical significance.

"Your Highness, this is truly a good thing, the high-end technology of our Taoyuan County!"

"In short, it's the best of magnifying glasses! You can use it to see things you can't normally see!"

"Clam?"

Fang Zheng took some water from the flowerpot tray next to him and dropped it under the microscope: "Look from top to bottom, and you can see what's in the water."

Li Yuanzhao moved closer, looked at it for a while with his butt sticking out, then exclaimed and quickly dodged.

Looking at Fang Zheng suspiciously, he said, "Is this... something in the water? Why is it so messy and something is moving? I think the water droplets are quite clean!"

"That's right, we can't see it normally. Diseases come from the mouth, which means invisible things can make people sick, so we have to pay attention to hygiene!"

"Your Highness, please study it first. I have something else to do and will be back soon. Don't break it. This is the only one in the county!"

Li Yuanzhao waved his hands impatiently, then stuck his butt out and started studying with great interest again.

Seeing that he was calm, Fang Zheng went straight to find Ao Chen.
