Speaking of this, Liu Yu couldn't help but get nervous.

It's simple to turn your face and don't recognize people, just Dai Jinxian's mathematical level, which is considered a master in this era, but in the eyes of Liu Yu, who went to school in his previous life, it is the same thing, the level of rough calculus, right?

But even if you turn your face and don't recognize people, you won't be in contact with each other in the future, so what's the matter with your previous close relationship? If something happens in the future, will someone take advantage of the opportunity to make trouble?

Liu Yu only felt a little sweat on his back, and muttered, "Yes, my son knows." However, Western learning does have merit, and if we cut off contact with the West because of this, I am afraid that it will be detrimental to the country? In the previous dynasty, Xu Guangqi was so talented, and he still praised Matteo Ricci's talent, and there were books such as "Geometric Original" and "Taixi Water Law" in circulation. Today, it's not just Chixian in Kyushu ......"

Liu Sheng sighed and said, "How can I not know? In the past, no one in the military government could preside over such a major event, so it could only be done by Western missionaries. The matter of the map, the life of the country, how can it be easy to deal with people? But there's no way, we won't. The map of the Celestial Empire surveyed and mapped by the French missionaries, then the passes, mountains and rivers of the Celestial Empire, the French people know everything! ”

"Measuring the calendar, there is no one in the Qintian Prison who can beat it, so he can only cry 'It is better to make Zhongxia have no good calendar, than to make Zhongxia have Westerners', but what is the use? Just like the Che Chi Guo fighting method in "Journey to the West", gambling on his life to calculate the solar eclipse, as a result, all the people in the Qintian Prison lost the bet, and after losing the bet, they refused to die, and the face of our country was lost. ”

"The former Ming Dynasty's "Wanli Ye was compiled" said that there was a ban on astronomy at the beginning of the country, and those who studied the calendar were sent to war, and those who made the calendar died. Freezing three feet, not a day's cold. ”

"Don't I know that there is something to learn from Western knowledge? But now the Holy See has sent people here, with arrogant rhetoric, forbidding Chinese believers to worship their ancestors, and demanding that the cities be fully opened to allow missionaries to come and go freely. Whoever doesn't allow it. ”

Liu Yu also sighed, he knew about the mapping of the Celestial Empire a few years ago, relying on French missionaries.

Because Galileo came up with the longitude measurement method for the moons of Jupiter to do standard time, a map of standard latitude and longitude appeared for the first time in the world, and Louis XIV saw a map of France with standard latitude and longitude for the first time, and he complained: Scientists have lost more land than I have lost a battle.

France is also known as the "filial son of God", and the Holy See is fighting with Dashun because of the ceremonial dispute, while France seized the opportunity to send missionaries, and there are even academicians of the French Academy of Sciences.

His father, Liu Sheng, said that my country is facing mountains and rivers, and the French people know everything...... In fact, why does the French know everything? Even some missionaries among the princes of the HRE who had never been to China were able to compile and draw a complete map of the Han provinces, marked clearly.

Surveying and mapping is the lifeblood of a country. Liu Yu is very clear.

In the previous life, all the longitude and latitude of civil maps were Martian coordinates, and it was strictly forbidden for other countries to survey and map their own maps.

Dashun is not brainless, the Ministry of Military Affairs is doing this, the four divisions of the Ministry of War, the weight of the responsibility cannot be faked to others, and the dynasty is not unclear.

But now they can only rely on Westerners, because the local surveying and mapping method is seriously distorted.

The terrain of mountains and rivers has been left by Westerners, and it will be a hidden danger in the future.

There is a great hidden danger, but if there is a little way, the thing of surveying and mapping must not be left to foreigners to do.

Now that the gap between the East and the West has widened, the blind fierce man Euler, who can mentally calculate calculus and solve the three-body problem of the sun, earth and moon, has emerged, and is about to unify the symbols of later mathematics textbooks.

The partisan struggle between the West French Party and the Old Conservative Party broke out at this time, and the Holy See was clinging to the issue of etiquette, and it was impossible for the two sides to reconcile.

The father and son sighed at each other, but after all, Liu Sheng still waved his hand and motioned for Liu Yu to leave.

"Just write it down, and don't spread the word about it. The booklet I just gave you, you should go back and read it, it will be very helpful. ”

"Yes. The son wrote it down. ”

Liu Yu touched the pieces of paper in his hand, and he didn't know what was written inside. Do fathers and sons still use dumb riddles? You just say no and you're done?

He bowed, retreated to the door with broken steps, pushed the door and left.

"It seems that the imperial court is going to ban religion?"

…………

Walking outside from the outer study, Liu Yu felt quite depressed, and the cicadas in early autumn were even more irritating and squeaking.

The steamed bun was still honestly waiting for him by the stable, and he watched Liu Yu bow his head and droop his horns from a distance, and he also had an ominous premonition in his heart.

hurriedly walked to the side, and Liu Yu remembered that there was a nervous little guy beside him.

"It's okay, it has nothing to do with you, you can rest assured."

"Hoo ......"

The steamed bun chief breathed a sigh of relief, reached out and stroked his chest, wiped the sweat on his forehead and said with a smile: "I saw that the third master had a bad complexion, and I thought that I was going to be beaten with the third master again." Since there is nothing to do, the little one will go to Quanliuju first to inform them, so as not to worry about those people. ”

"Well, good. I won't go, there are some things, I'm not in the mood to eat and drink. Don't say I'm not going, just say ......"

"These words are still the third master's teaching? I said that the third master was stopped by the prince and asked about learning. ”

Seeing that he was clever, Liu Yu smiled and took out a small piece of broken silver from his arms and threw it over: "It's just right, on the eighth day of the first month today, there is a temple fair in Huguo Temple." You just go play, I won't go out today, it's none of your business. ”

This is his confidant, who has grown up together since childhood, and the treatment is naturally different.

The steamed bun took the money and saluted, seeing that Liu Yu was still full of sadness, he said with concern: "The third master is in a bad mood?" ”

Liu Yu nodded, and said in his heart that he was in a good mood? Looking at the four seas rising to peace, in fact, the world has changed drastically, Lao Tzu doesn't want to eat and wait for death, and he doesn't want Dashun to repeat the humiliation after a hundred years, but after thinking about it, he can only sigh and say: "I have no choice but to pay Yaoqin, there are few bosom friends, who listens to the broken strings?" It's none of your business, you go and do your job. ”

Mantou didn't ask any more questions, went to the stable to fetch the horses and left.

Liu Yu was in a bad mood and needed to think about some things clearly, so he had to go back to his residence first.

He has not yet married and has no position, and now he still lives in the inner courtyard of the Guogong Mansion. Although the Guogong Mansion is large, the memories imprinted in the bones will not change, and it will not be impossible to find where you live.

Slowly passed through the outer instrument gate, and it was a courtyard more than twenty zhang wide. The front is a large front hall with five rooms, but this is not the main house of the Guogong Mansion.

Along the path full of flowers and plants, I passed through the front hall, and there was another instrument door, which was the inner instrument door.

After entering the inner instrument gate, further on, it is the main hall of the Guogong Mansion, with seven open halls, which is the system licensed by the Gonghou Mansion.

Under the business of Shinong, no matter how rich the merchant was, he could not build the main hall of seven rooms. That's trespassing, the crime of killing the head.

As usual, either the emperor decrees or the prince visits, this main hall can be used, and it is usually just a decoration.

Liu Yu's place of residence is still far away, there is a hall here in the main hall, walk more than 100 steps to the right after the hall, and then walk through two courtyards, which is where he lives.

Under the etiquette system, brothers and sisters cannot be together for too long. Once you reach puberty, you have to live apart. His sisters are in some courtyards behind the main hall, and his mother is also there, so that he can take care of and educate his sisters.

It is said that the dirty Tang stinky man, in fact, the prince's mansion doesn't care too much, mainly because he is afraid of going further, and directly makes out "Lu Dao is dangling, and Qi Zi is home." It is said that it is both a return to the end, and a stop is conceived".

The rules here are completely different from those of the previous life, and although the words are similar, they are actually two worlds entirely.

Liu Yu is not used to it after all, so he can only adapt slowly.

Moved to his own small courtyard, there are two white fruits in the courtyard, and the sun is shining, casting a little mottle.

A few little maids were sprinkling water there, and two little maids were carrying a long bamboo pole, on which were hung with clumps of gluten, and they were aware of it, probably because they were afraid that the annoying cicada song would disturb the child's dream.

Before entering the door, a maid wearing a green and yellow skirt greeted her, and without waiting for Liu Yu's instructions, she first brought water to wash her face, and stood aside with a towel in her hand and waited.

"Why did the third master eat this wine so quickly today?"

The little maid stood very close, exhaling like an orchid, and she also contained some mint leaves on weekdays, which was cool and itchy.

Without waiting for Liu Yu to answer, the maid handed over the towel and asked Liu Yu to wipe his hands. Sniffing the faint smell of wine exhaled by Liu Yu, he took back the towel, and said with a smile: "I knew that the third master was going to drink, and I prepared the maple birch dew from the north, and it was cold, just drink it, go to the wine." ”

While talking, Rou Yi dragged a towel in her tender hand and gracefully went to prepare maple tea.

There seemed to be some residual smell of fragrant powder on the girl's fingers on her face, and she turned to look at the other maids who were serving, Liu Yu pulled her fingers and pulled her waist, her bones gurgling.

I thought that after such a life, it was no wonder that the nobles had fallen so quickly. It is said that if you go to school in Wude Palace, you have to eat and live in Wude Palace for 100 days a year, otherwise you will not be rated as superior, but even so, some noble children feel bitter.

Feeling the little girl beside her, Liu Yu seemed to empathize. With such a day, who wants to go to Wude Palace to brush up on classes? If you don't fall, you can have ghosts.

The maid named Swift just now, who was extremely standard, was specially arranged by her mother.

In recent years, some things from the West have been introduced to Kyushu, including crops such as corn and potatoes, handicrafts such as glass clocks, and syphilis from the Americas.

It was the age of the bloody Fanggang, and her mother was worried that Liu Yu would go out to indulge in Hualiu, so she deliberately chose a delicate girl, hoping to make Liu Yu more nostalgic for her family and go to Hualiu Lane less.

It's not that it's a bad thing to be greedy for flowers and willows, it's just that I'm afraid of getting bayberry sores, which is not good.

But when the swift came for a while, as soon as the mother asked, the swift said that the third son either reads books or picks up stone locks on weekdays, but he never touches her and abides by etiquette.

It is said that this is a good thing in line with the "poetic rites", but my mother was anxious when she heard it.

The personal maid was sent, it was originally for the sons to vent, as long as you don't believe the nonsense in those scripts, and use an equal identity to fall in love with the master. If you fall in love, you have to fight to the death, but if you play with it, your family still supports it. It's better to be sparse than blocked, and your own maid is at least clean.

It's not that Yuyan doesn't understand what Liu Yu's mother means, but she can't pull her face down and make some foxy tricks, just looking forward to the day when it will come to fruition.

Liu Yu's mother heard Yuyan say this, at the age of sixteen or seventeen, she was indifferent in the face of a beautiful maid, could it be that her son has the good of Longyang and the habit of breaking sleeves?

Or is it that the son is young, and he doesn't like such a smart maid, but he likes those ripe women? If it weren't for the loss of face, I'm afraid that a well-known cook in the house would have been arranged a long time ago.

I had to arrange for someone to privately ask Swift a few words, all of which were red-faced words. With such a mind, the selected swifts are also beautiful in the world, and they are even more well-behaved and lovely.

At this time, the swifts had already made tea, and put some maple and birch dew from the bitter cold land in the north, and the fragrance filled the house.

Liu Yu took a sip of tea with the taste of maple birch, and the aftertaste was full, like autumn with a mountain of maple leaves in his mouth.

took a sip of tea and looked at the swift carefully.

At the age of sixteen or seventeen, thin shoulders, waist like willows, eyebrows and eyes like daisies, and a small delicate beauty mole under the corner of the mouth, her eyes are clear, she is indeed a beauty.

Yuyan also noticed that Liu Yu was looking at herself, and she didn't blush and bow her head shyly, making a smiling face, but the third master changed his mind today?

Could it be that those rumors that say that the third master has the good of Longyang are false?

Liu Yu recalled that he secretly scolded himself before he was really aesthetically pleasing and had a problem.

I don't have any habit of breaking my sleeves and splitting peaches, but I have followed a few gentlemen to some Fengyue places.

I have been messing with those women who have been in the Fengyue Field for a long time, resulting in a young age who actually likes the kind of plump and soft woman who takes the initiative to laugh, and the women in the Fengyue Field are really amorous.

Although the swift is good-looking, in the eyes of Liu Yu before, it is a sour fruit that has not grown, and it tastes sour and tasteless, and it is far less delicious than the soft and glutinous ripe peaches.

Before, he would rather be impulsive about the waist and hips of the cook lady and, and would not have the slightest interest in astringent fruits like swifts.

At this time, I changed my mind, and when I looked at it again, I felt quite tasteful. After looking at it for a while, he saw that Swift's face was a little red, so he looked away.

Swift's heart was pounding, and she asked in a voice like a mosquito, "The third master wants to take a nap?" Or do you want to read a book? ”

As soon as he said this, Liu Yu also remembered that he didn't know what to write on the few pieces of paper his father gave him, so he signaled that he wanted to write.

Yuyan followed Liu Yu for a long time, and when she saw Liu Yu enter the study, she hurriedly went to study ink. Liu Yu entered the study, looked at the books on the shelves, and shook his head self-deprecatingly.

"It turns out that my education level is really not low?"

He laughed self-deprecatingly, and his eyes swept over, only to see that the books on the shelves were really a little level.

The "Geometric Original" and "Taixi Water Law" co-translated by Xu Guangqi and Matteo Ricci in the previous dynasty are all Chinese translations.

In addition to the Chinese translation, there is also a half-volume manuscript of Boccaccio's Decameron.

Seeing these books, Liu Yu was even more convinced that the rumor that he was "not doing his job" was true, and he had a lot of exchanges with Western missionaries, and he even knew a lot of Latin.

And judging from the amount of information revealed in these books, I am afraid that among the Westerners I have befriended, there are all kinds of people, not just Jesuit missionaries......

I haven't heard of any missionary who can watch "Decameron", what is the difference between this and a monk watching "Monk of Lamp Grass"?

Except for these weird Western books, the rest are relatively normal.

A set of the first four histories, a bunch of military books such as "Li Weigong Asks Right", "Liutao", "Three Strategies", "Wei Xuanzi", and a "Lu Mi Gong" arquebus of the former Ming Dynasty.

Rumi, Roman, Roma, Rumilia...... Actually, it's Ottoman Turkey.

After all, Green Rome is also Rome.

At the end of the Ming Dynasty, Lu Miquan was already a little behind Western Europe, and the road was a little crooked.

This is the elite standard equipment of the fifth battalion of Dashun, but at this time, Britain is about to mass-produce the brown bass used in the Opium War. The generational gap has emerged. A glimpse of the whole leopard, Liu Yu probably knew the military strength and formation of Dashun.

At this time, the swift had already ground the ink, and in addition to the size of the writing on the pen holder, there was also a set of quill pens used to write foreign characters.

There is a small chiming clock on the desk, and next to the chiming bell is a glass mirror from Venice, and next to it is a Ruyao beauty like a slender waist woman in the palace of the king of Chu, with a bouquet of flowers inserted in it.

There was some purple smoke slowly rising from the incense burner on the table, I don't know what kind of incense it was smoked, it smelled very faint, just suppressed the faint strange smell in the ink.

Yuyan stood aside, fanning her fan obediently, carefully afraid that Liu Yu, who was blowing too much, would be uncomfortable.

Sitting at the desk, Liu Yu took out the booklet his father gave him, glanced at it a few times, and couldn't laugh or cry.
