Washing clothes and taking a bath made Wu Wu realize that there were really a lot of inconveniences in the Warring States period more than 2,000 years ago.

There is no soap laundry detergent, and the clothes are washed with plant ash, which can be washed clean?

If you want to wash it, you have to rub it vigorously and then beat it vigorously.

Originally, the hemp material was easy to break, but when it was knocked like this, it broke faster.

Seeing how the two apricot girls washed their clothes, they were anxious to make soap.

On this day, Gongzi Zheng came to study, and he took the money out and asked Aunt Yu to buy oil.

After buying it back, Aunt Yu thought she was going to cook or something, so she went into the kitchen and asked Gongzizheng to go to the kitchen without worry.

She took the grease and asked Aunt Yu and Qingxing to go out, and she took Gongzizheng to make handmade soap together.

Make soap, worry-free first let the son take the political test.

His hands were black because of the ashes of the grass and trees, and they were clean immediately after washing them with soap.

After washing his hands, Gongzizheng looked at the soap, his eyes were shining, and he didn't know what he was thinking.

Worry-free smiled: "There are others, if you want to learn, come often in the future." ”

In this way, Wu Wu and Gongzi Zheng were neighbors for more than a year, teaching him to learn papermaking and printing. He was taught how to make fruit wine, and how to grind wheat into flour, steam steamed buns with flour, make dumplings, and make noodles.

He also taught him how to make tofu, and of course, the most important thing was to teach Gongzi Zheng how to increase grain production.

Sanssouci originally thought he would stay here for a long time.

She originally thought that when Gongzizheng and Zhao Ji returned to Qin, she would also follow, and when she arrived in Qin, she could help Gongzizheng do more reform measures.

Who knows, she stayed for more than a year and less than two years, and Xiao Wan told her that she could go back.

I had been looking forward to going back soon.

But now that she's going back, she's still a little reluctant.

She got to know some people here, and she had a very good relationship with Zhao Ji and Gongzizheng.

At this time, the relationship between Zhao Ji and Gongzizheng's mother and son is very good, there is no tension like later, and she can't wait to kill each other, Zhao Ji is just an ordinary mother who wants to live her life and protect Gongzizheng to grow up well.

Gongzi Zheng is still just a child with a little temper.

There are also Qingxing and Aunt Yu.

Although these two people don't talk much, they are very dependent on worry-free and are particularly loyal.

Wuwu taught Gongzizheng so many things, and they all saw it, but they never said a word outside.

Wuwu later taught Qingxing to read and write, and also taught her to read some books, which made Aunt Yu more loyal to Wuwu.

Now that I'm leaving, it's okay for someone else, how can this mother and daughter arrange?

After thinking about it for a long time, he finally decided to entrust the mother and daughter to Gongzizheng.

It took her a few days to jot down a lot of things.

For example, how to make better iron, how to fire glass, and how to make repeaters.

After all, she just remembered what to write, a hammer in the east and a mallet in the west, and there was no qualitative.

Soon, it was time to leave.

Gongzi Zheng happily came over to find no worries.

A few days ago, Wuwu taught him what Arabic numerals were, as well as some simple accounting methods, and said that he would make a calculation tool with him that was better than arithmetic.

Gongzi Zheng was worried about this, and after coming over, he said to Wuwu: "Immortal, I found good wood, when will we do the calculation you said?" ”

Wuwu smiled and beckoned to him, and after he walked over, he took out a piece of paper and handed it over: "This is the appearance of the abacus and the preparation method, which are written on it, you can see for yourself." ”

Gongzizheng looked at it very seriously: "This is not difficult to make, but how to use it?" ”

yes, how do you use it?

Carefree waved her hand into the study, and when she came out later, she took several more pieces of paper.

"Here's the usage."

At this time, worry-free regret didn't bring an abacus when she came, if she had an abacus, she could show Gongzizheng how to use it, but unfortunately, now she can only draw on paper.

Gongzi Zheng was a little confused.

Wu Wu touched his head: "You put it away, when you become the king of Qin in the future, there will be many talents around you to work for you, and then select people who are sensitive to numbers and smart for them to study." ”

Gongzi Zheng looked up at Worry-free.

He seemed to realize something: "The immortals want to leave politics? ”

Carefree laughed: "I can't stay here for too long, it's time to go." ”

With just one sentence, Gongzizheng's tears fell all of a sudden.

Wuwu pulled him to sit down: "After I leave, you don't have to show off the ones I taught you, you have to hide them, and you will take them with you when you go back to Qin in the future, this is the foundation for you to go back and stand up, and you must take care of it." ”

Gongzi Zheng nodded vigorously: "I wrote it down." ”

Wuwu said again: "Aunt Yu and Qingxing will work for you in the future, if you go back...... If you can bring it, bring it, and ah, I have hidden a book in the secret compartment at the head of the bed in the room, don't read it now, and when you have the opportunity to return to Qin in the future, you remember to come and get it. ”

Gongzi Zheng snorted.

Worry-free smiled and hugged him: "Gathering and scattering is impermanent, fate is determined, you and I are only so fateful, don't be too forceful, after I leave, you all have to ...... well"

Xiao Wan has been urging worry-free: "Host, the time is up." ”

"Let's go back." Worry-free said to Xiao Wan.

One moment ago, he was still holding Gongzizheng's carefreeness, and the next second it dissipated into the air.

Gongzizheng got up suddenly, waving his hands and grabbing in the air, trying to catch Wuwu, but no matter how crazy he grabbed it, it would be impossible to see Wuwu again.

Soon, Carefree returned with the house.

She was in the bedroom on the second floor, and when she opened her eyes and looked out the window, the scenery had long since changed.

She saw a lot of tall trees, a lot of flowers, and a lot of asphalt roads that are characteristic of modern times.

Seeing all this, the worry-free mood is very complicated.

"Xiao Wan, how is the Gongzi Political Council?"

She asked.

Xiao Wan didn't know what would happen: "Host, the history of that time and space is already unpredictable. ”

Carefree sighed.

Instead of staying in the house any longer, she packed her things and drove to the city center.

Stayed in the house over there for a few days.

It's not just about staying in the house, she goes shopping like crazy, goes to the movies alone, goes to the playground, and plays with electric ......

After playing like this for a few days, I finally came to my senses.

I found the feeling of being in the modern era, sealed the memories of the Warring States period, and drove home without worry.

On the first night home, her live broadcast room was turned on again.

Under the canopy, in many time and space, hundreds of millions of people looked up to see the canopy lit up, and began to call friends again.

Soon, carefree appeared on the canopy.

"Hello everyone, I'm carefree, it's nice to see you all again."

"A few days ago, I invited Tang Taizong, Song Taizu and Ming Taizu to play, the live broadcast was postponed for some time, and today I happen to be free, let's continue to talk about those things in the Han Dynasty."

"I finished talking about the Western Han Dynasty last time, and this time I started talking about the Eastern Han Dynasty, who was the founding emperor of the Eastern Han Dynasty? Last time, we mentioned Emperor Jing of Han, who gave birth to a son for the country...... Yes, the founding emperor of the Eastern Han Dynasty is the descendant of Emperor Jing of the Han Dynasty, this is not ordinary, and he is known as the chosen son in later generations, okay, let's talk about the life of Emperor Guangwu of the Eastern Han Dynasty. ”
