In the following days, Fang Zhengyi inspected the county departments.

The sweet potatoes were handed over to the people of the Agricultural Department to carefully plant them and sent heavy troops to guard them.

You can also slow down the other things, and there must be no problems with this thing. Then you need to transport the things to the capital as soon as possible after the harvest is obtained.

The research institute has made rapid progress. With Fang Zhengyi's personal guidance and full efforts, magnifying glasses and microscopes have also been released one after another.

However, the microscope looks extremely rough and the effect is not very good.

Perhaps it is because the lenses are not polished fine enough, or the lens arrangement is not accurate enough.

But in the end, it is still useful, and you can vaguely see the microorganisms swimming in the water.

With this thing, penicillin research can be smoother.

The method of making penicillin left by Fang Zhengyi is very rough, but at least it makes people have traces to follow.

Although he poisoned more than 50 people, he didn't know what the specific problem was... It was probably because there were too many impurities in the bacteria.

Scientific research is most afraid of not finding a direction and wasting time and money. Founder Zhengyi does not understand technology, but being able to roughly know the direction of technology is like taking many detours.

After two days of research on penicillin, there was no progress. Founder Zhengyi decided not to wait anymore and packed up his things and went back to Beijing.

Before returning to Beijing, I packed a lot of things, including about ten magnifying glasses, two microscopes, and a large cart of sanitary napkins...

On the day of Fang Zhengyi's farewell, the whole city saw him off again, but the sadness of the crowd was obviously much better this time.

Obviously everyone knows that Fang Zhengyi will come back.

Ao Chen walked to Fang Zhengyi and said carelessly: "Master, please be careful when you go here. When will you come back next time?"

Fang Zheng was quite reluctant to see the crowd. His life in Taoyuan County was still comfortable, and at least he could have a good sleep.

"It's hard to say when you will come back. Ao Chen, there is still a task to hand over to you."

"From tomorrow, the roads in Taoyuan County will continue to be repaired, and I will be able to reach the capital in half a year!"

"It is difficult to build bridges when you encounter mountains and rivers. But I believe you have no problem. After the roads are connected, it will be no problem to communicate between Taoyuan County and the capital."

"Also, let the county's industries find ways to increase production capacity! After the roads are connected, I will be counting on you!"

After saying that, he got on the carriage and was about to enter the carriage, Yu Guang suddenly turned around and found a figure in a prison uniform among the crowd.

Fang Zheng pointed at the man together and said, "What? What is this man doing? He just ran out of prison?"

Everyone looked in the direction of Fang Zheng's finger.

A woman in a prison uniform walked out with a smirk.

"Sin girl... Oh, I've seen the master."

Seeing this, Ao Chen leaned into Fang Zheng's ear and smiled, "Master... This is a prostitute from Xueyuelou, wearing prison uniforms to act... Xueyuelou's new project, this is called Pure Prison Wind."

"I heard that it was created by Wu Sheng. Many people like it. They are all good at it. He also made a lot of money because of this."

Fang Zheng frowned. This old pervert has a lot of fun!

He whispered: "Stay closely, don't play too much and cause injuries. Also, this prisoner is taken from the county prison. Did Wu Sheng pay that dog? He is deducted 50% of the money!"

"I understand, sir!"

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

After another bumpy ride, the group returned to Fang Mansion. It was already evening.

After the meal, a group of people sat around the dining table.

On the dining table are sanitary napkins with hills high.

Looking at the sanitary napkins, Fang Zhengyi fell into deep thought...

This thing looks completely different from what I watched in my previous life's advertisements...

The middle is almost the same but there are no wings, and there are four long straps in the four corners, which is very confusing to see the style...

After a long time, Fang Zhengyi hesitated and said, "How to use this...?"

Everyone's puzzled eyes focused on Fang Zhengyi.

"What's this?"

"It's called sanitary napkins, menstruation."

Upon hearing this, Zhang Biao and Ruffa turned around silently, and went straight back to their room as if nothing had happened.

Bai Yi and Xiao Tao's faces turned red, and Bai Yi couldn't help but cover her face with both hands.

Xiao Tao said shyly: "Young Master! Why are you doing so many of this stuff? Take it away! It's still on the table, so embarrassing!"

Fang Zhengyi looked at Xiaotao in confusion: "Have you never seen this in the county?"

"No! I've been playing around these days...why am I watching it? Stop talking! Take it away!"

Seeing the two women's attitude, Fang Zhengichi was also a little helpless.

He specially designed the sanitary napkin to develop the sanitary napkins in the county, but later he found that only the textile factory could not complete the task.

I found a paper mill again. Although the production of paper mills in the county is not very high, it seems that the technology tree has been skewed under the influence of Founder Yi.

Paper is beginning to continue to move towards flexibility and durability.

Now that the two factories jointly manufacture this thing, it is a great achievement.

The reason why this thing is so important is that the ancients have been unable to regain their habits and have always regarded women's aunts as a disaster.

When life was not rich before, many women hid at home as soon as their menstruation came and did not go out until the end.

Not only are men afraid of women in this regard, but women themselves are also deeply ashamed of.

If you don’t care about it, just use cloth. If you are better, use something called menstruation cloth, which is filled with things like hay, carbon ash, and is used to absorb water and sterilize.

At first, Fang Zhengyi was completely unaware of this, but he often felt it in his heart if he didn't see Xiaotao for a few days every month.

Later, I ordered the county's medical clinic to collect information, and even set up a special female clinic for this purpose. I realized that many women were sick or died because of this incident.

Fang Zhengyi hates this bad habit!

This time I brought this car of sanitary napkins back, mainly because I wanted to try selling them to promote them. By the way, I found new growth points for Taoyuan County.

The glass products in the county are good, but that road... I still forget it and I can't get to the capital, and it will be completely broken. Even if I build a new factory in the capital, it will take a lot of time to cultivate reliable newcomers.

He doesn't have to consider civilians, but they can recommend them to the high-end market.

This piece costs three cents to a bowl of noodles. I don’t know how many pieces you need to use in a month, but it’s certain that ordinary people will never spend so much money on this matter.

We can only use high-end users first, reverse the social atmosphere, and then slowly plan for it after the sweet potatoes are promoted and society gradually becomes rich.

It's also a pre-preparation.

But this first step was difficult. He didn't know how to use this thing, and the two maids were unwilling to say it.

Fang Zhengyi was angry and slapped the table hard: "Xiao Tao! You said! What are these straps for?"

Xiaotao covered her face and said in a muffled voice: "It's tied around her waist..."

Fang Zhengyi suddenly realized and then touched his nose awkwardly. The ancients seemed to have no habit of wearing underwear... I forgot.

This is also a good business! Just have some fun underwear and other things...

After thinking for a while, an idea slowly took shape in Fang Zheng's mind.

But as soon as I looked up, I saw Bai Yi and Xiao Tao still covering their faces tightly, and Fang Zhengyi's temper came back.

What's going on? I don't care about my own problems! I'm still shy about solving them for you!

Fang Zhengyi slapped the table hard again and said loudly: "You guys listen to me! In the future, all women in the mansion will have to use this for me! Free use, must be used!"

"I have to tell me my thoughts after I use it! For example, if there is any leak... That's it!"

Then he thought that if he gave it for free, there might be two dealers in the mansion, so he added: "Everyone receives three pieces a day! Xiaotao, you are responsible!"

Xiaotao nodded shyly.

Bai Yi's palm quietly spread a gap and looked at Fang Zhengyi in horror.

Too perverted...
