In ancient times, there were many restrictions on brothers and women, who believed that their chastity was very important.

Although this idea is too patriarchal, one-sidedly speaking, avoiding women and brothers from getting close to outsiders when they are young is a kind of protection in disguise.

Therefore, when Qin Muwen was too free to instill the notion that Xiao Baozi could not be hugged, hugged, or kissed by anyone other than Daddy and Daddy, Li Jin not only did not stop it, but rather agreed.

Li Jin still remembers that in his previous life, he often saw news about girls or boys being molested, and even many criminals were acquaintances.

The most worrying thing is that those children first said that their buttocks hurt, and the parents did not realize what was happening.

Little Bun is now four and a half years old, and Li Jin usually only hugs him when he can't walk, and rarely kisses Bun on the cheek.

Although he is the father of Baozi, he is also a man.

Li Jin then thought about it, although her husband's life is always on guard, but at any rate his buns have a general idea of ​​this matter and will not be taken advantage of by others.

Qin Muwen bluntly changed the subject and asked Little Bun: "Is my brother awake?"

"No, Dad is in good health?"

Qin Muwen coughed slightly, not knowing what he thought of, his face was a little unnatural, and said, "It's much better."

Sure enough, the topic of the little bun was taken away. Seeing that he really missed Dad, Li Jin took him to the bed, removed his footwear and robe, and let him lie on the bed with Dad.

Baozi's little face was full of excitement, and he had been sleeping in his small room since he could remember.

Apart from rushing to the village or going back to the village, there are few opportunities to sleep with Daddy.

Baozi is very happy to be with A-da again today.

Seeing him cuddling with his dad, Li Jin couldn't help but smile and said, "Oh, dad will come back this afternoon."

"Yeah! Baozi obeyed!" Little Baozi nodded frantically.

Li Jin immediately went to Mr. Zhu Shan's house, and when he reached the door, he found that he was too excited after receiving the letter and forgot to buy a gift.

After he went back at night, he also recorded the incident in his diary. A hundred years later, the diary was studied by later generations and turned into a beautiful conversation.

In history, this day is even called the first "meeting" of two applied mathematics masters.

But at this moment, Li Jin only wants to share his research on ship dynamics with others.

Sooner or later, their country will have to build a sailing ship.

After seeing Li Jin, Zhu Shan was also taken aback: "I didn't expect the little friend to be so handsome."

I wish you a happy New Year, but because of the wind and rain all year round, the whole person is dark and strong.

He does not look like a scholar, but like a farmer who works all day.

But this made Li Jin feel close to him a lot. He smiled and said, "Mr. Zhu's research is well applied, and he must do everything by himself, and he admires him very much."

After a pause, Li Jin explained: "When I received a letter from my husband in the late birth, I rushed over directly. I forgot to bring a gift in a hurry, and I hoped Mr. Haihan."

It is indeed impolite to come empty-handed when visiting a respected elder for the first time.

But instead of being annoyed by Li Jin's failure to come to the door, Zhu Shan smiled and greeted him entering the door.

"I'm so happy that you can come, so why bother about those pompous gifts?"

There are not many people who can devote themselves to studying the scriptures in the dynasty. Li Jin is so young, and Zhu Shan has high hopes for him.

Zhu Shan has read through the book of "Meng Xue Shu", the content is easy to understand, and the examples are quite interesting.

Not only has the effect of popularizing mathematics, it can also bring up Mengtong's interest in mathematics.

Therefore, Zhu Shan is very optimistic about Li Jin, otherwise he would not write so many letters to him.

Li Jin did not live up to his expectations, and he rushed here as soon as he received the letter.It can be seen that Li Jin also really likes math.

I wish you good luck and sent someone to open a pot of wine.

"Let's drink and talk. I don't have any other rules here. As long as I'm interested in arithmetic, I will treat you with wine and food."

"Mr. has a nice temperament, and he admires him late."

In the subsequent exchanges, Zhu Shan asked Li Jin what he was studying recently and what plans he had in the future.

Li Jinzhi said that he has been studying shipbuilding engineering recently, covering both hull structure and dynamics research.

Zhu Shan's eyes lit up again. Don't blame him. The ancient traffic was blocked and Ningxing Mansion was far away from Beijing. Zhu Shan could only rely on guessing the direction of Li Jin's research.

He originally thought that Li Jin was studying and compiling enlightenment or elementary mathematics.

Unexpectedly, Li Jin's real research direction is actually the same as him!

How to make him calm down?

Zhu Shan stood up and sent someone to the study to get a pen. The pen was soaked in ink. He drew the bow and stern pointy on the paper, and wrote some general data.

"In this way, can you possibly estimate how big, heavy, and manned the ship is?"

Li Jin has been studying this recently, without even writing a pen, and directly reported the threshold of the ship's various data.

For one thing, Mr. Zhu Shan didn't embarrass him either. The data in it were very small and suitable for mental arithmetic.

Secondly, Li Jin has been studying the shipbuilding industry for a long time, and is already familiar with the algorithms in it. He even thought of a lot of innovative algorithms.

Zhu Shan laughed loudly. It was a confession to meet such a talented junior.

After that, Zhu Shan would ask Li Jin whether he was going to the Ministry of Industry or the dock of the Ministry of Industry at the Beijing Ferry if he had time to go with him. Li Jin couldn't ask for it, and naturally agreed to go with him.

Theoretical knowledge is one aspect, and personal operation is another aspect.

After all, it is not advisable to talk about soldiers alone, so Li Jin cherishes this opportunity very much.

The next day, Zhu Shan and Li Jin went to the dock of the Ministry of Industry Dushuiqing Lisi, Li Jin followed his husband, holding a pen in his hand, and recording data intently.

Occasionally, the results of discussions between Zhu Shan and officials of the Ministry of Industry will be recorded.

The official saw Li Jin's record and said with a smile to Zhu Shan: "Your little apprentice's ability to summarize and analyze is first-class, and it is clearer than the records of my chief executives here."

After a pause, he said, "Do you have a reputation as an apprentice? If so, come directly to me as a secretary, and you have some monthly salary."

The secretary is the eighth grade official position in the Beijing official, so many people can't get in.That person could directly open the mouth for an administrative position, I think it should be a high official of the Du Shui Qing official.

Zhu Shan raised an eyebrow and smiled: "Do you think he is good too?"

The official didn't understand what medicine was sold in Zhushan Gourd, but he had a good relationship with Zhushan, so he followed Zhushan's words.

"It's not bad, why are you not willing?"

Zhu Shan said: "No, he is not my apprentice, but the best companion to study shipbuilding with me. If you let him be a steward and take notes, you can be regarded as wronged."

The official's fierce eyes were as big as a copper bell. He had known Zhu Shanshao for ten years, and he had never seen any companions around him.

At that time when Zhu Shan's fame was rising, there were many people who wanted to cooperate with him.

Zhu Shan also readily agreed at first, but before the break-in period passed, Zhu Shan broke up with others.

The reason is that the roads are different.

This official knows one of the secrets. Anyway, he is on the side of Zhushan. This kind of hard work is just right for his taste.

He is very uncomfortable with people who talk about fake things all day long, but actually just want to make money.

Therefore, Li Jin can be recognized by good wishes, and his knowledge and character must pass the test.

In the evening, Li Jin and Zhu Shan walked into the city together. He arched his hands and said, "What Mr. said at the dock today..."

Zhu Shan didn't wait for him to finish, he smiled and said: "I am out of forty seven this year. I consciously look at people with accurate eyes. Li Jin, you are not such a traitor. I am clear about this.

One thing he didn't say is that Li Jin not only doesn't take tricks, but also loves applying mathematics.

Otherwise, he would not walk in a hurry when he visited on the first day, and came with empty hands.

Another month passed, and more and more people in the capital noticed that Zhu Shan had a companion beside him.

There are well-informed people who know that the man is Li Jin who was appointed by His Majesty to publish the book.

The rumor that Li Jin's'only studying the simple calculations' is self-defeating.

The things that Mr. Zhu Shan studies are all very esoteric and obscure. Li Jin can communicate with him day after day, so why would he only discuss learning and mathematics?

Besides, some people have seen Mr. Liu, a member of the Ministry of Engineering, have a meal with Li Jin and Zhu Shan, happily.

But not everyone can speak with these two adults at the same time.

There is no shortage of princes and nobles in the capital, and the news in the circle of scholars gradually spread, so that they also heard about this young generation.

At the same time, people from the General's Mansion also came back from Ningxing Mansion to inquire about the news.

Attached is a letter written by Pang Lao. The content of the letterhead is very Pang Lao's style. It is all about letting the General Mansion not bully or provoke his closed disciples.

Mo Erye: "...what does this provocation mean?"

The messenger said: "Back to the second master, no one else in Ningxing Mansion knew that Mr. Li was apprentice under Pang Lao's school. Hearing what Pang Lao said, don't announce his acceptance of disciples for the time being."

As the eldest grandson of the long house, Mo Zixuan wanted to follow along.

In today's General's Mansion, the old general has left his hands alone. Only Mo Erye and Old Taijun are in charge, and the other uncles are leading soldiers outside.

Mo Zixuan's abilities were developed step by step.

When his body first grows up, he will have to go out and lead soldiers to fight at the time of the 14th Five-Year Plan.

In more than ten or twenty years, the lintel of the General Mansion will be supported by him.

Mo Zixuan only heard his second uncle say: "Don't provoke, absolutely don't provoke, then Li Jin is only twenty-two, and immediately became my father's junior. Can I rush to find an uncle for myself?"

Mo Zixuan: "..."

The old lady couldn't bear it and knocked on his son's head.

The old lady is a sensible, she held back the others and asked Mo Zixuan: "What do you think about this?"

Mo Zixuan said: "On the way back to Beijing this time, Grandson and Uncle Li had some contact. I can see that he is capable and vigorous and doesn't depend on the nobles. What he does will be obscured by the fame of the old disciple Pang, which is not conducive to his development in mathematics."

Mo Erye clapped his hands: "Yes, that's the truth."

The old lady also admired it very much, but she still added: "A Xuan, there is one more thing you didn't expect. Li Jin has won four yuan from the county examination, the government examination, the hospital examination, and the rural examination. Fame, it is not impossible to compete for Huiyuan and even the final champion. And if everyone in Beijing knows that he is a disciple of Old Pang, then he must think that he will develop in calligraphy in the future, which will affect his imperial examination future."

Mo Zixuan nodded seriously, he was listening.

The old lady continued: "Although this is the truth, he is the younger brother of your grandfather and father. Let the shopkeeper of General's Mansion Shusi ask him to meet him at Shusi another day. Second, you have to be a good hospitality."

Mo Erye's head hung down: "Yes." Isn't it half an elder!His second master did not panic.

Li Jin ran around every day and was a little tanned by the sun.

On this day, when Xiao Baozi entered the house in Li Jin, he looked at his father eagerly all the way.

When his father's gaze fell on him, Xiao Baozi stretched out his white and tender arm to compare with the back of his hand and said, "Daddy is dark."

Li Jin: "..."

Qin Muwen was holding a small leopard, so Wen Yan couldn't help but smile: "I said why he kept asking his father when he would be back today, so I was waiting for this sentence."

At this moment, the little leopard in Qin Muwen's arms suddenly said: "Father...hey!"

Li Jin: "...?"
