Farmer Xianlang who traveled through time

"Brother, what I saw with my own eyes is what he did!"

Li Jinlin suddenly got up and stood up, with an excited expression on his face, he shouted loudly, "Don't you believe me?"

"Lin'er, sit down!" Li Zhenghao stared at him and snapped, "Calm down, let's see what you look like."

"Brother, brother, he doesn't know each other..."

"It's not that he doesn't believe you, what he means is that Jiang Yu'er may have someone backing him up." Li Jinshu said flatly.

"Lang'er is smart." Yan Xuanyi smiled slightly, "That's exactly what I meant, I'm afraid someone deliberately disturbed the peace of Calabash Village."

"It's possible."

Li Zhenghao nodded, and cast sharp eyes on his son Li Jinlin, "Especially you, don't be impulsive when you encounter something that you can't handle, come back and find someone."

"Father, I understand." Li Jinlin still knew the seriousness of the matter, and obediently nodded in agreement.

"Yulan is so pitiful." Li Jinrong showed sympathy, and Yang Yulan was also one of her good friends.

"The Yang family is in trouble, I hope we can survive."

Li Qiushi sighed softly, "Your elder brother will bring Yulan to help you, so you should treat him better in the future."

"Mom, I know!"

……

The base of the new house of the Li family was full of hustle and bustle, and Yan Xuanyi stood in it wearing a plain long gown.

He was instructing the craftsmen to lift the huge wooden beams and columns, the surface was repaired very flat, the craftsmen chanted and lifted them to prepare for the recess.

The craftsmen on the pavement leveled it with a wooden hammer, and the walls and woods were tightly fitted together, as if they were integrated, and the shape of a courtyard has begun to take shape.

The old courtyard of the Li family looked a little peaceful and serene!

The brothers and sisters of the Li family were sitting in the yard, each writing a book, while a girl dressed as a maid waited beside them.

"Brother, what are you writing? Why are they all so ugly, like ghost charms." Li Jinrong raised her head, frowning and asked suspiciously.

"What ghost talisman? You're talking nonsense. These are called Arabic numerals." Looking at the Arabic numerals on the paper, Li Jinshu laughed and scolded.

"Arabic numerals? What are they?"

"A method used exclusively for bookkeeping."

Li Jinshu explained and glanced at her, "Are you familiar with the multiplication formula?"

"Small meaning, I got familiar with it yesterday." Li Jinrong showed a little pride on her small face, picked up the paper she wrote and handed it to him, "Brother, check if it's right, I just wrote it silently."

"Really?" Li Jinshu raised his eyebrows, "Let me take a look first."

"Uh!"

It was the first time that Li Jinshu saw the multiplication tables with uppercase numbers, and Li Jinshu had a weird expression on his face.

"Brother, I did not make a typo!"

"I haven't finished it yet."

After all, Li Jinshu is familiar with the formula, so he read it quickly, and a smile appeared on his handsome face, "Yes, it seems that you are really familiar with it."

"Of course!" Li Jinrong's small face was filled with a bright smile, and her tone was flattering, "Brother, you should teach me other things now!"

"No problem, today I will teach you Arabic numerals."

Putting the Arabic numerals he had written in front of her, Li Jinshu instructed: "You not only need to learn to recognize, but also to be able to write."

"Be able to read and write!"

Li Jinrong pointed at something that looked like a ghost symbol, and gestured for a while, her little face flushed more and more red.

"Yes, you can read and write."

Seeing her like this, Li Jinshu couldn't help laughing, "When you learn Arabic numerals, you will find it very simple and convenient."

"Brother, can't I use capital letters?"

"No, unless you're not going to learn how to do business with me."

"I, I learn!"

Li Jinrong put away her bitter expression, and her eyes gradually became firm: "I don't believe that I can't learn it."

"What is Rong'er going to learn again? Are you familiar with the multiplication formula?" The figure followed the voice, and Yan Xuanyi appeared at the gate of the courtyard.

"Brother, you are back."

Li Jinrong smiled at him, "The multiplication formula has passed, brother is going to teach me Arabic numerals."

"Arabic numerals? What are Arabic numerals?"

Hearing the novel trick again, Yan Xuanyi became a little interested, "Show me, what are Arabic numerals."

"Here, bro, take a look." Li Jinrong handed it to him.

"This……"

It was completely unfamiliar symbols, Yan Xuanyi frowned slightly, glanced at Li Jinshu in surprise, and said with a smile: "It's very interesting, Lang'er, don't mind if I listen in!"

"No problem, pay the tuition!" Li Jinshu stretched out his hand, and Li Jinshu would not miss the opportunity to ask for money.

"Tuition fees are easy to talk about, pay the debt first!" Yan Xuanyi gave him a sideways look, with a righteous expression on his face.

"shameless!"

Li Jinshu glared at him with contemptuous eyes, gritted his teeth angrily, "Get away, I will teach you and I will teach you."

"Lang'er is gentle and generous, don't worry about such trivial matters."

A certain person looked serious, and preached seriously, "Teaching one person is no different from teaching two people. Well, they can also study together."

He pointed to Yang Yulan next to him, seeming to explain or remind him, "Rong'er will need her help in the future, it will be easier for Rong'er to learn these things."

Li Jinrong's eyes lit up, and she exclaimed happily, "Ge Lang is right, Yulan will learn with me."

"Rong'er really needs help, and Yulan is just right."

Nodding slightly, Li Jinshu waved to the people beside him, "Yulan, come here."

"Young master, please order." Yang Yulan walked over with a stiff and nervous expression.

"Don't be nervous, Yulan, do you understand what we mean?"

Li Jinshu smiled and said in a very gentle voice, "Of course, if you don't want to, we won't force you to study."

"Yulan, don't be afraid, I can teach you what you don't understand in the future." Li Jinrong promised generously.

"Eldest son, eldest miss, I, I am willing."

Yang Yulan nodded heavily, clenched her small fists tightly, showing gratitude.

"It's fine if you want."

Li Jinshu smiled, "When Rong'er is free, I will teach you how to read first. As for other content, don't worry, just learn it step by step."

"Yes, eldest son, Yulan understands."

"Hee hee, Yulan, I will teach you well."

"Thank you Miss, Yulan."

"Okay, it's all my own people, don't thank me."

Li Jinshu interrupted their conversation, and said again: "The strokes of Arabic numerals are relatively simple, especially for the convenience of accounting, and they are clear at a glance."

"One vertical, it has the same meaning as the capital one, this one looks like a symbol, it represents the meaning of two, the same as the capital two..."

Explain the Arabic numerals while writing a capital next to it.

Not only is the explanation clear, but it is clear and clear in comparison.

For the convenience of keeping accounts, Li Jinshu didn't know what kind of disturbance the Arabic numerals created by him caused in this time and space.

Thousands of years later, Arabic numerals were called "Li Jinshu numerals" by later generations.

……

"Aww—"

"Squeak creak—"

"Don't worry, don't worry!"

Ignoring the little guys who were eager to reward them, Li Jinshu stared at them and said, "I said, you have drank a lot of my Qi Condensing Pill liquid recently, why haven't you become a spirit demon yet?"
