Chapter 250 Fang Yiyu: You still say that numbers were not invented by you?

Fang Xuanling was furious, not because Yaya was his goddaughter.

Mainly, the Marquis of Lantian’s Mansion was an important place in the Tang Dynasty, and His Majesty had sent people to protect it. Why would there be more than a dozen thieves breaking in?

Their purpose was to rob and kidnap.

For a moment, Fang Xuanling’s heart was covered with a layer of fog.

“Liu Xuan, have you offended anyone recently?”

“No, Old Fang, you know me, I’m ordinary, I don’t like to make trouble, and I’m not the kind of person who takes the initiative to provoke others.”

Fang Xuanling frowned. It was true that the Marquis of Lantian had only smashed some colored glaze in Chang’an so far. This kind of behavior was just a drizzle among the nobles. Who hasn’t done such a thing?

What else can those Hu people, ordinary people, say?

They should not be Hu people, nor ordinary people.

“Then who will they be?”

At this time, a footstep appeared quickly in the backyard.

"My Lord, I got it!"

Liu Xuan glanced at Xue Rengui who was running fast. Xue Rengui might eat a lot, but he was definitely not a reckless man. When he saw Liu Xuan talking to Fang Xuanling, especially when Liu Xuan showed doubt, he immediately knew that he should show up with the so-called confession.

When Fang Xuanling saw the confession, his face quickly became dusty and gloomy.

Fang's plan and Du's judgment, Du Ruhui used to like to hide himself in the dark. Now that Du Ruhui is gone, Fang Xuanling found that he was more and more like the combination of the two.

Xingyang Zheng, these four words directly appeared in Fang Xuanling's mind.

"Liu Xuan, don't worry, they are just some petty thieves, haha, we have to strengthen our vigilance at home in the future."

Liu Xuan smiled calmly, understood, and said nothing: "Eat more, eat more, and tell Miss Fang about the way to settle the account later."

At this time in Chang'an City, in Pingkangfang, on a luxurious attic, Zheng Youlai was constantly brewing tea for the old man.

"Grandpa, my little sister is young and naive. Don't worry about it. Someone from our family has already gone there. We should be able to find her soon."

While speaking, Zheng Youlai still quietly glanced at the old man's face.

The old man's face was very calm. He looked at the spring scenery mixed with the boundless autumn scenery in Pingkangfang, and his face was calm.

After a while, a hoarse voice with firm majesty came.

"Your sister is naive. Are you naive?"

"She was the prince before, then the King of Yue, and then the descendants of the nobles. She didn't see any of them. She ran away all day long. It's clear that she didn't take you, her brother, seriously."

At this moment, footsteps were heard under the attic.

"Master, Master, the young lady went to the Lantian Marquis' Mansion!"

As soon as the four words Lantian Marquis' Mansion came out, Zheng Youlai's heart trembled instantly.

He didn't know this Lantian Marquis, but he had eaten at the Datang Hotel. He heard that the Lantian Marquis was conferred by His Majesty because the dishes at the Datang Hotel were so delicious that His Majesty lingered there.

"Marquis of Lantian?"

"Someone in the family has visited him many times, but he has never been seen. Is this Marquis of Lantian a person who keeps himself to himself?"

"Impossible. Since ancient times, no one in the court has been innocent."

The old man narrowed his eyes: "You bring someone to the door."

Zheng Youlai felt uncomfortable all of a sudden. The other party was Marquis of Lantian. Although Zheng Youlai was famous among the scholars in Chang'an, he was still just a scholar and had not entered the officialdom properly.

With this identity, he went to see Marquis of Lantian? This is not appropriate.

"Grandpa, this seems a bit inappropriate. How about letting uncle go?"

The old man was silent for a while and continued: "You can go. Zheng family of Xingyang is willing to go to see a marquis who came from a commoner family. It has given him face."

"Cheng Yaojin didn't have this face back then."

Zheng Youlai felt a little bitter in his heart. He has always taken good care of Zheng Liwan and has many ambitions. He also knows one thing, that His Majesty seems to be full of resentment towards the aristocratic family.

Why does the family need Zheng Liwan to get to know those people now? Isn't it because the family's power has become smaller?

What kind of operation is this? I don't understand it, I can't figure it out.

But since the old man in the family said so, just do it.

...

When Fang Xuanling left, Fang Yiyu hadn't left yet. He was in Liu Xuan's study, staring at the strange symbols written in white ash on the ink-colored board.

Zheng Liwan was pouring tea and water on the side, and she was also very curious.

"Liu Xuan, what is this?"

"You can call this a number."

"Numbers? Aren't they all..."

Fang Yiyu picked up the brush and wrote down the Tang people's counting method on the paper. Numbers are actually just Chinese characters.

Liu Xuan looked at the beautiful handwriting and nodded: "Indeed, but it is not convenient to record. From today on, whenever you use numbers, you have to use this."

"This is 0, this is 1..."

Zheng Liwan on the side poked her head out, as if she was listening to a book from heaven. She also learned the method of accounting when she was a child and knew how to calculate. Some strange methods were extremely difficult to remember, but these seemed to be no problem for Liu Xuan.

After an incense stick, Liu Xuan asked: "Miss Fang, do you think you remember these 0 to 10?"

Fang Yiyu's face showed doubts: "Liu Xuan, this is too simple, of course I remember it, is it that simple?"

Liu Xuan smiled: "It's normal, it means you are talented and smart!"

Few people dare to say that mathematics is simple. You can say that this question is simple, but if you say mathematics is simple, especially if you say it loudly in some cafeterias near the mathematics college.

Immediately, many eyes will look towards you, with enthusiasm in their eyes, just like a teacher who sees a good idea and is about to give a question.

After some discussion, Liu Xuan discovered that Fang Yiyu could memorize Arabic numerals very quickly.

"Liu Xuan, did you invent this number?"

Liu Xuan looked at Fang Yiyu seriously: "Miss Fang, you can't talk nonsense."

"I'm just picking up people's wisdom. This number was invented by someone from a foreign country. It's just that it's very convenient to use, so many people have learned to imitate it."

Fang Yiyu's eyes flickered, and he was already making calculations in his mind.

Although this Liu Xuan was an upright man, he never told the truth.

Last time he said he couldn't write poetry and didn't like reading. So how could you write those famous lines?

Later, he said that he was not interested in money. It was okay not to be interested in money, but why did you earn so much?

Now you say you didn't do this.

Are you a liar?
