"Sir is right, Sir and Miss Ali are both children."

Li Xiang pursed his lips and tried his best to hold back a laugh.

The teenagers of the Tang Dynasty all developed very early, and even their minds and bodies developed earlier than those of later generations.

But, for the gentleman, it's still a little too early, right?

"Alright, I'm going home, where's that guard of yours?"

Having arrived at the gate of the palace, Yang Jian stopped and asked Li Xiang behind him.

"He's almost there, sir, please wait a moment."

Li Xiang looked at the people coming and going in front of the palace, and the crowded Suzaku Street, although it was only separated by a wall, it was two different worlds.

"yes, okay."

Yang Jian carried his hands behind his back, looking like a little old man.

"By the way, sir, are those numbers you teach today really from Arabia?"

Thinking of what Mr. taught in class today, Li Xiang asked again.

He has always been a studious prince.

"Of course."

Yang Jian was a little absent-minded, he just wanted to go back early now, lying on the kang of Xu Geng's house, even if the kang was uncomfortable, it was more comfortable than now, his small waist was still painful!

"What is Arabia?"

Li Xiang really studied hard and asked questions.

"Ah, ah? Arab? ”

Yang Jian suddenly realized something and asked in surprise.

"Yes, sir, where is Arabia? Why are the people there so clever that they can think of representing numbers in such a simple and easy-to-remember symbol, and it is very convenient to calculate? ”

Li Xiang looked at Yang Jian, grabbed the last moment before he left, and asked shamelessly, you know, it will be two days before I meet my husband again.

"Eh, Arabia, Arabia is the big food in the Tang Dynasty!"

Yang Jian remembered that Arabia in history textbooks was the great food country of the Tang Dynasty.

"But the students know a lot of Arabs, and they don't use these symbols to represent numbers, do they?"

As the prince of the Tang Empire, Li Xiang is naturally well-informed.

"Oh, really?"

Yang Jian was shocked, he had forgotten when Arabic numerals were invented, could it be that in the Tang Dynasty, the big cannibals didn't know Arabic numerals?

"yes, how did the gentleman know?"

Li Xiang broke the casserole and asked to the end.

"Oh, that's right, Arabic numerals are only common in a small tribe of today's big food country, my grandfather met a small tribe of big food country to do business in Datang by chance, it was he who taught my grandfather to use these Arabic numerals to represent symbols, but, in fact, according to that person, these Arabic numerals were not the first to be invented by the people of the big food country, the people of this tribe said that they first learned from the neighboring Tianzhu country and brought back to the tribe."

Yang Jianxin mended his lies by the reins.

"So that's the case, so the people of Tianzhu are also very smart."

Li Xiang knew that at the beginning of the founding of the Tang Dynasty, Emperor Taizong had filmed a monk to go to Tianzhu to learn scriptures and seek the law, and after returning to the country, he still preached the law in Chang'an for many years, but the monk did not bring back the symbolic counting method of this number. Perhaps, if necessary, next time I should ask my father to send envoys to Tianzhu Kingdom again to learn their advanced cultural knowledge.

Li Xiang obtained knowledge and information from Yang Jian, but he thought more far-reaching.

"It should be, okay, Third Highness, the guards have arrived, I'll go first, we'll see you the day after tomorrow!"

After Yang Jian finished speaking, he ran to the side of the horse in three steps and two steps, and then stretched out his hand, the guard took his little hand, and he jumped up with the help of his strength, and sat on the horse's back.

"Goodbye!"

Li Xiang looked at Yang Jian's figure leaving in a hurry, and always felt that today's little guy was preoccupied, maybe he was scared by Princess Xianyi and them during class today?

Thinking of this, Li Xiang couldn't help laughing again.

But his brother couldn't laugh at the moment.

"Mao'er, you said that your husband punished you for copying the Book of Poetry ten times?"

Concubine Wu Hui watched her young son sit at the desk, copying the thick book of poetry - where did this come from? How dare you punish her son? And it's still punished for copying the Book of Poetry ten times?!

"Mother, it's Mao'er's fault first, and Mr. should punish Mao'er."

Li Mao's little hands are not as big as the brush, but he grasps them very steadily, stroke by stroke, neatly worked.

Today's events, the initiator is really not him, when he heard that his husband was the child he saw at the New Year's poetry party that day, it was the sudden appearance of the child, and the three emperor brothers that night suddenly showed great courage and won the year's poetry award in one fell swoop.

Although he knew that the Three Emperor Brothers' victory over Shikui had nothing to do with Mr. Xiao, at that time, he was a friend of the Three Emperor Brothers, but he was sure, so as soon as his two little sisters heard that it was him, they thought of a way to rectify this little gentleman, and then from the advice to the specific implementation, it was the two younger sisters.

But the fault of his two young sisters can only be borne by himself, because the reason why the two younger sisters did that was not to vent their evil anger for themselves" and what Mr. said at that time was so serious, thirty canes? Don't you beat your two sisters to the soul?

"Shangxian, Xianyi, you two come here!"

Concubine Wu Hui has long heard about what happened in the Thirteenth School Park today, and it was her two precious daughters who caused the trouble, but now she wants her brother to be punished for them.

"Mother?"

The two princesses, Shangxian and Xianyi, knew that something was wrong when they saw the clouds on Concubine Wu Hui's face, and they came from the corner of the study at this moment, and they were also trembling all the way.

"The good things you two have done, but let your brother suffer, you say, should you two also be punished?"

Concubine Wu Hui looked at her two little daughters with a very angry face.

Compared with her two daughters, she loves her son more, only her son can bring her supreme glory in the Tang Empire, and only his son can compete for her in the future for the infinite country of the Tang Dynasty!

Whoever harms her son will kill her!

"Mother, we know it's wrong—"

Xian Yi Shangxian's face was frightened.

"Knowing mistakes is not a substitute for forgiveness, since my brother was punished by Mr. Xiao to copy the Book of Poetry ten times, and you two sisters also accompanied your brother to be punished together, you now go and get paper and pen, and copy the Book of Poetry ten times carefully and neatly for me!"

When Concubine Wu Hui spoke, her face was still blazing with anger.

"Mother?"

Of course, the two princesses Shangxian and Xianyi knew what a huge project it was to recite the Book of Poetry ten times, and they were immediately frightened.

"Scared? If you're afraid, you dare to encourage your brother to do these things? You don't know that my brother is now like a prince, he must be sensible, courteous, law-abiding, and be an example for all princes and the people of the world! ”

Concubine Wu Hui's mind is only known to herself, only if you suffer hardship, you can become a master, even if you are a prince, you must pay, only by paying with all your strength, can you get all you want!

"Okay, mother-"

As soon as Xianyi and Shangxian saw Concubine Wu Hui's angry face, they knew that this catastrophe was sad.

"Mother, don't blame my sister, my sister is also angry for me, and besides, the little gentleman has indeed been rectified, and I am also very happy, but the younger sisters are still young, so my mother will spare them, and I will bear all the punishments. Mother rest assured, Mr. only punished me to copy the Book of Poetry ten times, and it was not to be whipped, and copying the Book of Poetry is also beneficial to children. ”

Although Li Mao is young, she has a unique perspective when she sees problems and thinks about things.

"Son, do you really think so?"

Li Mao's answer was unexpected by Concubine Wu Hui, but it also made her feel comforted.
