Datang: Acting as a celestial mystery at the beginning

Who is Wang Xiaotong? Li Yi'an can also find the answer in the systematic material inheritance. The mathematician in the early Tang Dynasty was the first mathematician to study cubic equations. His book "Jigu Suanjing" is one of the ten books of Tang Dynasty Suanjing , is the mathematics textbook of Guozijian.

Since he was studying cubic equations, Li Yi'an revealed to him some solutions to cubic equations in advance.

The first sentence is the solution that Wang Xiaotong proposed later, and he probably hasn't thought of it now, and it was also advanced by Li Yi'an.

The second sentence was proposed by Qin Jiushao in the Southern Song Dynasty. The solution of the cubic equation in one variable and any higher-order equation, the positive and negative formulas, are of great use to Wang Xiaotong.

The achievements in mathematics in ancient China were also very great.

These esoteric words, to Li Liangping and others, seemed like a fairy tale. They didn't understand what it was, and they were about to refute Li Yi'an, but when Wang Xiaotong closed his eyes and pondered, he held back immediately.

He was worried that Li Yi'an would slap his face again.

After a while, Wang Xiaotong opened his eyes and said, "Come here, bring me a pen and paper!"

Immediately, someone brought a pen and paper, and Wang Xiaotong sat on the side, writing down Li Yi'an's two words just now, as well as some of the insights that appeared in his mind at that moment, for fear that he would forget them later.

After writing a full page, Wang Xiaotong stopped writing, cupped his hands, and said respectfully: "Lang Jun's two words made me think a lot. In terms of spells, I am far inferior to Lang Jun!"

what!

Everyone has forgotten how many times they were shocked today, and now even the prince they respect admires Li Yi'an so much, as if they heard it wrong.

Li Yi'an hurriedly turned sideways to avoid his salute: "Your Majesty's words are serious, but in fact I'm just like that."

Wang Xiaotong tidied up his sleeves, changed another ceremony of apprenticeship, and said more respectfully: "The two sentences just now completely solved the problems I have studied for many years. These are all taught by your lord, so I want to pay respects. Your husband is your teacher!"

He really wanted to be a teacher, and he thought he was not as good as Li Yi'an, so he didn't feel ashamed.

As soon as this remark came out, it exploded from the crowd like a bomb.

The prince is a representative of the highest level of the Tang Dynasty, and he wants to worship Li Yi'an as his teacher. Who can accept this?

The most difficult person to accept is none other than Li Liangping. In today's Chang'an Poetry Festival, he was originally the leading actor, but Li Yi'an appeared in the sky, stealing his limelight, and even taking away his heroine.

Just now he respected Wang Xiaotong very much, but he never thought that Wang Xiaotong would turn around and worship Li Yi'an as his teacher. This is stepping his self-proclaimed talent into the mud.

"Li Yi'an, you...why do you insist on fighting against me?"

Li Liangping shook his body, his blood surged up, his eyes darkened, and he passed out from anger.

He is the flower in the greenhouse. How could he have suffered such setbacks? Just like Lu Deming, he couldn't bear the failure.

"Brother Liangping!"

Lu Xiuran immediately supported him, and then called the people from the Li family over, but he didn't dare to do anything to Li Yi'an, so he had to leave Furong Garden with them.

"Young people these days really can't stand setbacks!"

Li Yian let out a long sigh.

Everyone looked at him strangely, thinking that you are also a young man.

"Lang Jun, please accept me!"

Wang Xiaotong was not affected by Li Liangping's coma, and said respectfully again.

Li Wenkang was puzzled, he also wanted to be a teacher, but the one who wanted to be a teacher was that little girl Wanshun, why the prince is also like this, he wants to be a teacher who is so much younger than himself.

"Impossible!"

Li Yi'an raised his bowing hand and said, "My lord, how old am I? How can I be your teacher."

"Teachers, there is no age distinction, those who have mastered are teachers."

Wang Xiaotong said with certainty.

"No, absolutely not."

Li Yi'an saw that he was completely unwilling to give up, so he had no choice but to say: "How about I talk to Wang Gongping, you can just call me Yi'an, and we will study the problem of spells together later, how about?"

Wang Xiaotong thought about it carefully, and thought it was not bad, he said with a smile: "It's the best, it's the best."

Li Wenkang hurried up and said, "Lang Jun, I want it too. In fact, I still want to worship my little sister as my teacher, but... I'm sorry."

"You're so stupid, I won't accept you!"

Wan Shun pursed her mouth, her face full of pride.

They were all amused by the little girl.

"Okay, let's go back!"

Li Yian waved his hand.

At this time, Wang Rujing suddenly whispered a few words in Wanshun's ear.

Xiao Wanshun took Li Yi'an's hand and gently swayed, "Brother-in-law, it seems that you haven't written any poems today, and those poems were all written by you before."

Li Yi'an coaxed her and said, "Okay, I won't write any poems, let's write a poem first!"

word?

According to the research of later generations, Ci is not unique to the Song Dynasty. It may have originated in the Sui and Tang Dynasties. There are other sayings that it is derived from long and short sentences in the Book of Songs.

However, the words at this time were still folk music, which also originated from the folk, and their status was not high. Even in the Song Dynasty, it was just the song of Hu Yili Lane. Even when Su Dongpo and others sorted out their anthologies, the words were put at the end.

Li Yi'an is going to write lyrics here?They all froze for a moment.

"The sound of the flute swallows, Qin E's dream breaks Qin Louyue. Qin Louyue, the willow color every year, Baling hurts farewell."

"On the Qingqiu Festival in Leyouyuan, the ancient roads of Xianyang are full of sound and dust. The sound of dust is perfect, the west wind shines, and the Han family mausoleum is quelled."

Before they could react, Li Yi'an had finished reciting the poem and walked away.

The rest of the people are reminiscing carefully. The lyrics are based on Leyouyuan as the background, and they are written about the sorrow and sorrow. It sounds very sad, but the Qingqiu Festival is a bit off topic.

However, Li Yi'an will not change!

He has no way to change the words of Li Bai, one of the ancestors of the hundred generations of lyrics and music.

Cui Rongrong could tell that this word used Xiao Shi Nongyu's allusion, and compared her own situation, she couldn't help but sneer.

What did she get after waiting for so long?

It's sad to get nothing.

Back in the carriage.

"Sir, you are showing off today, are you satisfied?"

Wang Rujing laughed.

"You didn't make trouble for me!"

Li Yi'an kept a straight face on purpose, and said, "Next time, don't use Wanshun to instigate me."

"My brother-in-law loves me the most."

Wanshun happily hugged Li Yi'an's arms.

Li Yi'an was about to hug her, when suddenly he frowned, a bad premonition filled his heart, he did a simple calculation, and immediately shouted: "Stop!"

Almost at the same time, the traveling carriage stopped, as if echoing Li Yi'an's words.

"Sir, Ma'am, there is a strange person blocking the way outside!"

"He's really weird," said the driver driving the car.

"Take Wanshun back first!"

Knowing the danger, Li Yi'an opened the curtain and jumped out of the carriage, only to see a man in black clothes, whose face could not be seen, standing in front of Li Yi'an.

He is the wolf lord.
