Not long after Jin Yutang's maidservant left, Mo Shiyun and her personal maidservant came to the door of the Li Mansion not far away, and the two of them were still dressed as men.

Mo Shiyun's footsteps became slower and slower, and finally stopped, and she was confused for a while. What if he wants to copy "Drumming" by himself when they meet? What if I go out alone to meet a strange man and my parents find out?

Seeing her stop, the maid knew the contradiction in her heart, and took her hand and persuaded, "Forget it, let's go back." What kind of "Geometric Original" looks like you have lost your soul, these days you are stunned, all day long non-stop writing and calculating, people have been stunned. ”

As soon as she heard the words "Geometric Original", Mo Shiyun squeezed the book in her hand hard, her eyes became firm, and she walked towards the Li Mansion again.

Mo Shiyun can't make an objective evaluation of the value of this book for the time being, but it is undeniable that this book has opened up a new world of mathematics, and the content of the book is completely different from what she has learned before.

From the five simplest axioms, countless geometric theorems are deduced step by step. The logic of the derivation process is extremely rigorous, the whole logical system is unquestionable and irrefutable, and the reasoning process can only be summed up by the word "perfect".

There is such a thing in the world!

Mo Shiyun sighed, but in the process of studying, she couldn't understand some of the difficult questions in the book. For the problems on this overseas mathematical masterpiece, I am afraid that no one in the Great Song Dynasty can answer it, unless it is Li Hao.

After a fierce ideological struggle, Mo Shiyun decided to come to the door to seek advice. It takes a lot of courage for a lady to come out alone to meet a strange man. A few days ago, Mo Shiyun couldn't imagine that she had the guts.

At the door of the Li Mansion, the porter stopped Mo Shiyun.

Mo Shiyun's maidservant said: "This is the second son of Mo Mansion, Mo Fan's younger brother, and he came to visit Li Gongzi. ”

Li Hao didn't see outsiders casually, but Mo Fan was a frequent visitor to the Li Mansion, and the servant who guarded the door hesitated for a moment, feeling that the people from the Mo Mansion were coming, and they should still be informed. "Childe, please wait, I'll go and tell my young master."

The servant hurriedly ran over to tell Li Hao, Li Hao frowned when he heard this, Mo Fan's younger brother? Mo Fan has only one sister, could it be a cousin? However, since he is a member of the Mo family, he naturally wants to meet him, "You take him in, and I will wait for him in the living room." ”

As soon as they met, Li Hao was surprised: "It's you?!" ”

Mo Shiyun's face flushed slightly, "I've seen Li Gongzi!" Thanks to Childe for the gift of "Geometric Original", after reading this book, the little woman has a lot of puzzles, Childe is a generation of mathematical masters, the best in learning, and I beg Childe to solve my doubts. ”

"What? A generation of grandmasters? Li Hao shook his hand again and again, "No, no, no, my math level is very shallow, I never dare to be a generation of grandmasters, girl, don't say that again, if you are an expert, you will laugh off your big teeth when you hear it." ”

Don't say it's yourself, even if you are a doctor of mathematics, or even an expert from the Institute of Mathematics of the Chinese Academy of Sciences, do you dare to call yourself a grandmaster in mathematics? Do you dare? Do you dare? Do you dare? Nima, if this is a generation of mathematical masters, then what are the shining names of Cadilla, Gauss, and Euler?

A generation of grandmasters is definitely not counted, but if it is only said that it is the best in mathematics, this seems to be a proud admit. It is now the thirteenth century, and the modern mathematical system is far from being established, and its own level of mathematics is indeed ahead of this era.

Li Hao saw that Mo Shiyun's face was a little strange, and asked, "What's wrong?" Is there anything wrong with me? ”

"Ah, no, it's just ......"

Li Hao smiled: "What can I say directly, my face is thicker than the city wall." ”

This is the most ordinary sentence in the main world, but it is the first time that Mo Shiyun has heard people compare their face with the city wall, and they feel very fresh, she chuckled, "I thought you were very arrogant when we met last time, but I felt very humble this time, this has changed too much." ”

"Actually, it's not arrogant and modest, it's just facts. By the way, I have been a tutor and taught students, so you can just ask any questions. ”

Mo Shiyun was secretly surprised when she heard this, you must know that the Song Dynasty has great respect for teachers, and it is not simple to be able to be a teacher, the so-called heaven and earth monarch teacher, although the "teacher" in this arrangement respects the last position, but can be ranked with the king and parents, which has already shown the degree of importance to it.

Li Hao has taught students at such a young age, how great is that? However, Mo Shiyun thought again that with this person's academic level, at least in mathematics he was much better than his previous husband, and it was not surprising that he could teach students.

Mo Shiyun poured out the questions he didn't understand, Li Hao answered them one by one, and he was surprised by Mo Shiyun's progress in reading: "In just a few days, you have read so much?" ”

Mo Shiyun nodded: "I don't have anything to do these days, I just keep reading this book." ”

Li Hao was stunned, you must know that this "Geometric Original" is not a pastime book, this book is even more difficult to bite than a mathematics textbook, because the textbook has been systematically arranged, and there are many examples from shallow to deep. This little girl read nearly a third of this book in just a few days, and listening to her questions, you know that she has learned quite thoroughly, and if she had been forced to eat this book back then, her self-learning progress would definitely not be comparable to her.

Li Hao couldn't help but secretly admire, if she grew up in the 21st century, she would have a proper master of science, or even a doctorate. But if she had grown up in a 21st century atmosphere, would she still be able to maintain her interest in mathematics? I'm afraid it's unlikely. How many girls in the Overworld would be interested in math?

After talking about the problems on "Geometric Original", it was still early, and the two chatted all over the world.

The more Mo Shiyun listened, the more shocked she became, how could a person's knowledge be so profound? My brother once said that this man knew astronomy and geography, and he knew 500 years before and 500 years later. She thought it was her brother bragging, but in the midst of small talk, she realized that it was true.

Mo Shiyun finally knew why her brother came to Li Mansion to chat with Li Hao whenever he was free. It is indeed a pleasure to talk to this person, to increase knowledge, to open up the mind, to be exposed to some unthinkable, thoughtful but reasonable ideas.

What's even more rare is that there are still some words that are extremely funny, until she left the Li Mansion for a long time, Mo Shiyun still had a smile on the corner of her mouth.

After this day, Mo Shiyun came to Li Hao from time to time, sometimes pulling her brother Mo Fan along, sometimes Mo Fan wanted to review, so she quietly slipped out with her maidservant and went to Li's mansion.

Time passed day by day, Li Hao's summer vacation will end in about a week, and all the work of his photo studio is ready, and it will be officially opened in a day or two.

Mo Shiyun and Li Hao are also very familiar with each other, and they come to Li Hao almost every other day, either to ask questions on "Geometric Original", or simply to chat, and eat Li Hao's ice cream by the way. Li Hao suspected that this girl was already addicted to ice cream, otherwise why would she keep running to herself?

The official office of the Great Song Dynasty Quanzhou City.

The Municipal Department of Foreign Trade is the official body that manages foreign trade, and a considerable part of its functions are similar to those of the customs of the main world, including the collection of customs duties, the seizure of smuggling, and so on.

Zheng Zhongyong, the chief officer of the Quanzhou City Shipping Division, sat with a gloomy face, and an official of the Municipal Shipping Division walked in quickly and saluted Zheng Zhongyong.

Zheng Zhongyong pointed to the stool next to him and said, "Sit, Ji Tong, how are you doing?" ”

Ji Tong was a little embarrassed and said: "That Li Hao's origin is mysterious, and the Treasure Pavilion seems to have opened overnight. The subordinates investigated in many ways, and they didn't know the origin of those goods, and it was impossible for Dashi, Daqin, and Persia to make those products. ”

Zheng Zhongyong shook his head and said: "It doesn't matter where the goods come from, what matters is who Li Hao's backstage is." ”

"The subordinates feel that this Li Hao seems to have no backstage, and he has not found out that he has dealings with officials."

Zheng Zhongyong sneered: "No backstage? Do you believe that? Didn't he later dare to blatantly sell goods that were not taxed by the city? Is it still openly listed as an overseas treasure? Without a backstage, he can avoid the sea patrol boats, and can he transport goods directly into Quanzhou without anyone knowing? ”

Ji Tong stroked his chin with a small goatee, and his eyes flashed: "Why don't you send someone to test it?" ”

"Confused, before we find out his backstage, can you let our people go out for interviews? If he was supported by a certain big man in the court, then the Treasure Pavilion was actually the money cabinet of that big man, and you dared to reach out? Even if you have a long life, don't harm your own officials. ”

"It's because the subordinates are not thoughtful, so what should we do now?"

"Keep checking, and only quietly, don't let him find out. No action can be taken until a thorough investigation has been made. Go down. ”

"Yes, the subordinates will continue to investigate. Subordinates retire! Ji Tong withdrew.

As soon as Ji Tong went out of the door, a messenger came in a hurry: "Master Ji, I found out a new piece of news about Li Hao." The yacha whispered in Ji Tong's ear.

Ji Tong's eyes flashed, "The news is reliable?" ”

The yacha patted his heart and said: "The villain's third brother is the third housekeeper in the Liang family, can his words be wrong?" ”

Ji Tong patted the Yacha on the shoulder, "Very good, your news is very timely, and after I and Master Zheng finish this matter, your reward will be indispensable." ”

"Thank you, Master Ji." The yacha smiled so hard that his eyes narrowed into a line, and he walked away happily.

Ji Tong's face turned cold, he snorted lightly, knocked on the door again and walked into the room.

"My lord, my subordinates just got the news that Li Hao took over the Liang family's industry, took over all the Liang family's residences and fields, and just made a note yesterday. My lord, it seems that Li Hao will not be the agent of the princes of the court, and it is impossible for the princes of the court to buy a house here. And according to the third housekeeper of the Liang family, Li Hao has nothing to do with officials at all levels. The eldest son of the Liang family is Cai Xianggong's person, and their news is the most accurate. ”

Zheng Zhongyong stood up with a sigh and walked a few steps beside the bookcase with his hands behind his back.

Ji Tong said in a low voice: "Then Li Hao has no background at all, just stunned." We were almost frightened by him. ”

Zheng Zhongyong returned to the bookcase, sat down slowly with both hands on the bookcase, and said in a deep voice: "Don't be reckless, just rely on the words of a subordinate in the Liang Mansion, it is not enough." In this way, you go and meet the people of the Liang family and be careful to verify it. To make sure that Li Hao has no backstage, we can do it. But be quick, you can't miss the opportunity, the things of the Treasure Pavilion are worth a lot, if we wait for other officials to know about the situation, we will miss the opportunity. ”

"My subordinates will do it."

After Ji Tong left, Zheng Zhongyong casually picked up a book on the bookcase and flipped through it, but he couldn't read a word, he muttered: "Rare Treasure Pavilion, hehe, Rare Treasure Pavilion." ”
