Gu Xinran became interested and urged him to speak quickly. Grandpa Gu also came over to listen to Duan Yunchi's method. In two days, the villagers should arrive.

“Next to this farm, there is another farm of 200 mu. They can buy it together and divide the land among themselves.

I'll find someone to sign a separate deed for them and establish a new village. This will be better than living in another village, but it will cost a lot of money. The price of the farm is 2,100 taels."

The villagers of Qingshan Village were not short of money. Not to mention the silver they received from Qingfeng Village, they earned more than two thousand taels just from selling Gastrodia elata.

The problem that had been bothering Gu Xinran was solved by Duan Yunchi. He gave him a thumbs up and praised him, "Cousin, you have a really good brain!"

Grandpa Gu was beaming, his wrinkles at the corners of his eyes overflowing with joy. "Yun Chi, that's amazing! You've helped us a lot."

Duan Yunchi was often criticized, but rarely praised. Now that two people were praising him at the same time, he felt elated and said sweet things, "If you have anything to ask of me, I will definitely take care of it!"

I originally wanted to visit Gu's mother's farm, but I found that the direction was different, so I couldn't go today. However, I still had time to rush to the government office to complete the formalities.

An hour later, they returned to the government office and, accompanied by Duan Yunchi, paid more than 30,000 taels of silver notes. They were not even asked to pay the deed fee, and all the procedures were completed quickly.

At Grandpa Gu's insistence, only the five-story house and the farm were registered under Gu Yuchen's name, while the remaining two houses and the storefront were registered under Gu Xinran's name, to be used as her dowry in the future.

The matter was settled and everyone was happy. Gu Xinran felt very happy because she was also a person with property.

After returning to the Duan Mansion, Grandpa Gu and Grandma Gu looked at the deeds of the mansion and the farm again and again, and the word "satisfaction" was written clearly on their faces.

For dozens of generations before the Gu family, no one had ever owned such a luxurious house and a 500-acre estate.

History was rewritten in Gu Yuchen's generation, but unfortunately all the tribesmen were killed or injured when the earth dragon turned over, and no one came to share their joy.

However, the Qingshan villagers will be arriving soon. They are also relatives and can share as well.

At dinner time, the general and Gu Yuchen came back.

There were bruises on Brother Gu's face, probably because he trained too hard, but his whole body was glowing and full of vitality. The happiness of being able to fight for his ideals overflowed from him.

That’s great. People should live like this, doing what they want to do and living the life they want.

The general was very happy for them when he learned that they had bought the house, shop, and farm they wanted. When he learned that they had spent a huge sum of over 30,000 yuan, he quickly took out all the money he had and stuffed it into Gu Xinran's pocket.

"After purchasing so many properties, you must be short of money. Here are over two thousand taels. Spend them first."

Gu Xinran was at a loss whether to laugh or cry when she saw her uncle's behavior. Her uncle was really good to them.

She was too rich to take advantage of such a thing, so she quickly refused, "Please take it back. I've made a lot of money selling medicine and wine. Don't worry, I have enough money to buy a few more farms."

The general saw that she did not seem to be lying, so he took back the silver. In fact, he was very poor, and whenever he had silver, he could not help but give it to the soldiers in need. He had to ask his nephew for it.

The dinner was spent in laughter and joy, with people talking about moving into their new home in a few days.

After dinner, Duan Yunchi couldn't wait to pull her to the second courtyard.

The west wing of the second courtyard was crowded with people. Many accountants were doing preliminary verification work, and the account books and counting sticks covered the table.

There were piles of account books in Duan Yunchi's study. Gu Xinran couldn't help but be amazed and really wanted to take back her boast that she could finish it in two days.

But our Miss Ran is a man of her words and always keeps her word.

If you want to speed up the process, you must simplify the account books. First, you have to teach them Arabic numerals, and then teach them simple accounting tables.

One is to teach, and a group is also to teach. Gu Xinran asked Duan Yunchi to call in his trusted accountants.

She first prepared a lesson plan, listing the words corresponding to the Arabic numerals one by one. She couldn't help but sigh, she never thought that she would become a first-grade math teacher in ancient times.

When Duan Yunchi brought people in, there was one more person, her boyfriend who she hadn't seen for a day. Gu Xinran saw that he looked okay and felt relieved.

When Xiao Mingzhan heard that Ranran was going to teach everyone a new bookkeeping method, he couldn't resist his curiosity and followed her to attend the class.

The two smiled at each other without much greeting.

After everyone was seated, Gu Xinran began to earnestly teach everyone about Arabic numerals, and how to record tens, hundreds, thousands, tens of thousands, and hundreds of thousands, and to shorten the long traditional Chinese numbers into simple characters.

He then brought out rice paper and taught them to make tables based on the contents of the account books, listing the serial number, date, summary, income, expenditure, balance, and person in charge one by one.

She picked up a random account book and asked Duan Yunchi to read it. She filled in the items one by one. Soon, the thick book was condensed into a page of paper, which was intuitive and simple.

Those who come here are the elite accountants in the city. They understand as soon as they hear and learn as soon as they are taught.

They were amazed by this simple and clear way of accounting. The resentment they felt when they first came in turned into admiration. They could not believe that a little girl could have such a brilliant idea. They, the old accountants who had been in charge of accounts for decades, felt ashamed of themselves.

Xiao Mingzhan witnessed another powerful side of his young wife. Fortunately, such an outstanding person is his own.

Duan Yunchi was still immersed in the new accounting method at this time. Following this method, he soon finished organizing an account book, but the calculations were also very complicated.

Seeing that they were fiddling with the abacus too slowly, Gu Xinran decided to be a good person to the end.

Based on the first table, I taught them simple addition, subtraction, multiplication and division, carry and borrow, and finally the multiplication table was listed out for them.

Gu Xinran taught without reservation, but the people below were more and more surprised the more they learned. Can such efficient and advanced knowledge be learned without becoming a disciple?

Looking at the two big guys who were studying harder than them, he thought to himself that he might have benefited from their help.

Everyone was once again impressed by Gu Xinran's talent and vision.

Xiao Mingzhan and Duan Yunchi learned the fastest, and the more they experimented, the more shocked they became. This method was many times faster than counting sticks, and it was a groundbreaking advancement. If it could be promoted nationwide, the people would benefit greatly.

Xiao Mingzhan's deep gaze fell on Gu Xinran, and he felt a sense of unreality. How could a girl who was less than fourteen years old know so many things? Not only was she good at making medicine and brewing wine, but even her arithmetic was not in the same system as everyone else's.

Could it be that Ranran is really a fairy sent by God to save him?

Duan Yunchi directly asked the question on everyone's mind, "Ranran, your accounting and arithmetic methods are so ingenious. Did you invent them yourself?"

We cannot take credit for this. The computing system that has been slowly formed through the experience accumulated by countless generations cannot be claimed as our own.

"How is that possible? I just happened to see it in a miscellaneous book. I thought it was very interesting, so I tried to learn it."

Duan Yunchi's eyes were full of amazement, "Ranran, you are so lucky, only you can come across such a rare book."

Xiao Mingzhan was half-believing and half-doubting, but it was not surprising that his young wife had one more secret. His destined person was just so extraordinary.

Seeing that everyone had learned almost everything, Gu Xinran wanted to slip away. Counting accounts was too boring. Wouldn't it be nice to just lie down and eat and drink?
