I am engaged in construction in Datang

The punch hit hard.

Xiaoqiu hadn't gotten used to the pain yet and was stunned for a moment, which gave the man a chance to escape.

The other party slipped out like a loach, trying to distance themselves from each other, but Xiaoqiu, who had reacted, grabbed his ankle with one hand and pulled hard...

"Good boy, you have amazing strength!" The man was shocked and said, "Fighting requires more than just strength."

After saying that, the man followed the hand that Xiaoqiu was holding and dragged the other person over with force.

What's the point of being strong? This weight can't control the situation at all!

Look at this boy, he is not short, just very thin.

If a man were to grab her and lift her up, she would be unable to resist.

Xiaoqiu immediately let go of the opponent's ankle and punched the opponent's arm with his left fist.

"Hiss!" The man groaned in pain and let go of his hand.

This is going to break his bones!

It was no use being careless, so the man started to use some fighting skills, and before long Xiaoqiu started to fall into a disadvantage.

"Little guy, strength alone is useless!"

After the man said this, he tripped Xiaoqiu to the ground and picked her up before she could react.

"You are very strong, and I can't trap you, but if I throw you down like this twice, how many times can you withstand it?"

"But those hits you made on me really hurt!"

The man thought for a moment and was a little bit unbelievable: "You showed mercy with your strength? Then I have to thank you..."

In just one or two seconds, Xiaoqiu raised her fist again and was about to hit the man's chattering mouth, but was thrown out before she could hit him.

He fell so hard that it seemed as if all his internal organs were displaced.

Fortunately, she has small breasts, otherwise they would have been exposed in the fight.

"Little wolf cub, eat more." After the man said that, he turned around and left with his brothers arm in arm, still crying out in pain.

Seeing that there was nothing exciting to watch, the people around immediately dispersed.

"You're great, kid!" Zhao Tianzhu couldn't help but walk over. After all, Xiao Qiu was his man.

"Do you want me to avenge you?"

"I knocked that guy down with three punches." Zhao Tianzhu pointed at the man's back. The man turned his head and saw his fierce eyes, and ran away in fear.

"I'll report it myself." Li Xiaoqiu propped himself up and stood up slowly.

This forced persuasion failed, we will try again next time.

Apart from the captain, only the military doctor knew her gender in the mansion. She had to go and have a look to avoid any problems that would delay her training.

"You have a temper!"

Zhao Tianzhu looked at his back and shouted, "We still have to train in the afternoon, don't be late."

……

In half a day, you can see all the beautiful buildings and pavilions, and the whole city of Chang'an is full of brocade flowers.

"Sister Li Yin, what do you think of my outfit?"

Li Yin looked at Wang Erya's clothes for the eighth time. She had two buns on her head, one on the left and one on the right, with a cherry headdress on it. She was wearing a lotus pink dress and had big round eyes. She looked very cute.

"She is very beautiful. I have never seen a girl cuter than Jingyi." Li Yin answered again without getting tired of it.

"Will the master accept me?" Wang Erya was very nervous: "I am a woman."

Li Yin smiled and touched Erya's head. Zhuangzi had told her about Erya's situation in advance, and the other party meant to assess her qualifications personally.

She didn't think Erya was worse than others, but she couldn't guarantee that the other party would accept her.

Bureau of Historiography.

Li Chunfeng drank tea and waited for Li Yin to bring people over.

Master Li personally endorsed that the girl was a rare mathematical genius. The other party also sent her many mathematical books, which made him study day and night for several days.

The owner of the manor said he didn't mind the secret transmission, so he asked his disciples to take a look at it as well. However, they couldn't understand much in the first few chapters, let alone the calculus in the later part?

"Li Shilang, Master Li is here." The servant hurried in. He had been waiting at the door as the other party had instructed.

"Ask me to go and meet her." Li Chunfeng's eyes lit up and he put down the teacup.

Over there, Li Yin also walked in with Erya, and the two groups met.

"Li Shilang." Li Yin bowed with a smile.

"Master Li, I have long heard of your name." Li Chunfeng returned the greeting and then looked at Wang Erya. Is this the little genius?

"Li Shilang, she is the child I mentioned before." Li Yin pushed Erya forward: "Her surname is Wang, and her name is Jingyi."

"Jingyi meets Li Shilang." Wang Erya stepped forward to greet him at the right time.

"Hey!" Li Chunfeng was happy when he saw this girl: "She looks very smart."

"Let's go inside first." Li Chunfeng led the two of them inside: "I have a lot of questions that I would like to ask Master Li to answer."

The three of them entered the room and a servant poured them tea.

"Master Li, I have been immersed in these advanced mathematics books these days, and they have really broadened my horizons." Li Chunfeng sighed, these things are much more advanced than what he has studied.

"This math is very useful!"

For example, Li Chunfeng thought that calculus could be used in business.

Nowadays, only the "Ji Gu Suan Jing" records how to find the positive roots of cubic equations, and these things can only be regarded as intermediate mathematics in the mathematics books given by Master Li Zhuang, not even advanced.

"Li Shilang, mathematics is the cornerstone of science and technology. If you want to develop the Tang Dynasty, mathematics is indispensable."

"When we are officials, mathematics can help us estimate the living standards of the people in the coming year. When we are civilians, mathematics can help us measure the land and calculate the area. When we are craftsmen, mathematics can help us calculate the stability of the structure. When we are businessmen, mathematics can help us calculate the gains and losses of profits."

Li Yin drank a sip of tea to moisten her throat. There were already three makeshift teams in the college (physics, chemistry, and medicine). If they could trick the mainstays into coming, there would be no need to worry about the rest.

"That's true." Li Chunfeng understood what Li Yin said. If one studies it deeply, he will know how terrible mathematics is.

"Master Li, what has Jingyi learned now?"

Hearing this, Li Yin smiled.

Arya is much better than her, even better than the child prodigies she had met at that time.

"I'm almost done with advanced mathematics."

Li Yin said: "If Li Shilang doesn't believe it, you can test it."

Li Chunfeng's eyes widened. Some of his disciples who studied mathematics with him couldn't even understand elementary mathematics at the age of 8. How could Wang Jingyi, an -year-old kid, almost finish learning intermediate mathematics?

Are you lying to me?

"Then I'm going to ask a question."

Li Chunfeng wrote the question on the paper with a mysterious look on his face: "Let a＞0, b＞0, if…"

The question is not long. It just uses the geometric mean to find the minimum value of a function.

This was made up by Li Chunfeng based on the contents and exercises in the math book. He could guarantee that the little girl had never seen it.

"Jingyi, you do the math." Li Chunfeng handed the pen and paper to Wang Erya, his eyes full of disbelief.

The question was not difficult. If it were placed on a math test, it would be no more than a multiple-choice question. Wang Erya knew what was going on after just two glances.

She began to calculate, and in just a minute or two she had the answer.

"The minimum is 8."

Li Yin also looked at the question and the answer was indeed 8. She nodded and gave Erya an appreciative look.

When they looked up again, they saw Li Chunfeng's dazed expression.

"ah……"

Li Chunfeng said: "This girl, please be my personal disciple."
