Dragon cubs are the group pet of the Qing Palace

In fact, I don’t blame Kangxi. After all, the main purpose of the missionaries who entered the Qing Dynasty was to preach, and they didn’t care about bringing in the latest theories from the West.

Kangxi himself was very interested in mathematics. When he studied mathematics with Nan Huairen, he even translated terms such as "root", "yuan" and "time" by himself.

He also set up the Mengyangzhai Mathematics School in Changchun Garden for the children of the Eight Banners to learn arithmetic.

Under the influence of Kangxi, the elder brothers are also good at arithmetic, but Yinzhen can discuss the contents of the books brought back with Kangxi.

What Kangxi held in his hand at this time was "Mathematical Principles of Natural Philosophy" translated by Yinzhen, and it was inevitable to ask Newton, the author of this book.

"If you go back to Huang Ama, it is said that this person is the president of the Royal Society of Great Britain." Yinzhen said.

When Kangxi heard this, he subconsciously thought of Louis XIV's French Academy of Sciences, and couldn't help thinking deeply.

After the father and son chatted for a while, Yinzhen bowed and left.

He left from the imperial study room but didn't go out of the palace directly, but went to see Cheng'an on the way.

Liu Cai saw him coming, saluted and told him softly that the little guy was sleeping.

"Why are you sleeping at this hour?"

At this time, it was said whether it was early or not, and there was still a little time before noon, so Yinzhen was a little confused.

Liu Cai was about to reply when he heard a voice from behind——

"Ninth Brother!"

Yinzhen saw the little guy sitting up on Luohan's bed rubbing his eyes, and walked over in three steps at a time.

"Where is the fourth brother? Isn't An An writing?" The little guy raised his head and asked suspiciously.

Seeing him asking herself in reverse, Yinzhen felt a little funny, but she could tell that he was writing and fell asleep while co-authoring.

The fourth brother is really, how old is the little guy, as for asking him to write so many words so early...

Yinzhen slandered in his heart, sat next to Luohan's bed and asked him: "How many words have you written?" He fell asleep while writing.

Seeing him sitting down, the little guy moved his little butt and leaned against him, then counted with his fingers, and told him after counting: "An'an wrote ten characters!"

"You fell asleep after writing ten characters together?" Yinzhen was a little dumb, thinking that he had wrongly blamed the fourth brother.

Cheng An probably heard the surprise in his tone, and couldn't help puffing up his cheeks slightly.

"I mean Cheng An is really amazing, he actually wrote ten characters!" Yinzhen immediately said after seeing his expression.

Only then was the little guy satisfied, and turned his head to look around.

"What are you looking for? The fourth brother should have left." Yinzhen saw his movements and said.

"Where's Brother Ten?"

It's no wonder that Cheng An subconsciously looked for Yin'er when he saw him, it's because the two of them have a good relationship, and they basically appeared in front of the little guy together.

Speaking of which, although Yin'e has a good relationship with Yinhu and Yinzhen, but in terms of being the closest, it must be Yinzhen. After all, the two are only a few months apart in age, and they grew up together since childhood.

When Yinzhen heard him ask Yin'e, it was difficult to say that Yin'e was restraining her feet, so she said: "Your tenth brother has something to do, so I probably don't have time to see you recently."

"What is Brother Ten busy with?" Probably in the little guy's impression, Shu Yin'e had the most time to play with him, and when he heard that he was busy, his tone was full of doubts.

Yinzhen heard his tone, and couldn't help being a little funny: "Huang Ama didn't punish him for copying books, he has to be busy copying books."

After the little guy nodded, he suddenly waved to him.

Seeing his movements, Yinzhen frowned slightly, and then lowered her head in cooperation.

"Ama wants An An to copy the book too. I said no, so I don't need to copy it~"

When Yinzhen heard the little guy whispering in her ear, the corners of her lips rose slightly, thinking that he could just say that, if Yin'e dared to say that, her legs would be broken by Huang Ama.

"So Huang Ama asked you to write?" Yinzhen smiled.

The little guy nodded: "Yeah."

"Then how much do you write?" Yinzhen asked again.

Cheng An stretched out his hand again, counted with his fingers and told him: "An An wrote ten~"

It's been a while since the little guy returned to the palace, and now that this year is over, he still only wrote ten characters, and if he guessed correctly, it seems that he wrote it today, Yinzhen didn't know what to say for a while.

Yinzhen thought that if the fourth brother was not there, he might not even have written these ten characters, and thought to himself: I really blamed the fourth brother...

"Ninth brother?" Seeing that he suddenly stopped talking, the little guy tilted his head and looked at him.

"You are so courageous." Yinzhen rubbed his head and then reminded, "If you have time, please write quickly, don't wait for Huang Ama to ask you that you haven't written much yet."

"Understood~" The little guy agreed very quickly, but when Yinzhen asked to accompany him to write for a while, he immediately talked about him, "Ninth brother, can you tell a story to An An?"

Yinzhen saw that he didn't want to write, and thought that it would be noon soon, and he wouldn't be able to stay for long. In the end, he didn't force it, but casually told him about the content behind Robinson Crusoe.

After telling the little guy a story, Yinzhen got up and left, and Kangxi came back not long after he left.

"Ama~"

After a good night's sleep, the little guy woke up with better spirits and ran to the door to meet him when he heard the sound.

When Kangxi saw his younger son, he bent down and picked him up, and asked him what he did this morning as he walked inside.

"An'an is learning poetry from my fourth brother~" After the little guy finished speaking, he shook his head and recited it.

Kangxi nodded slightly when he heard it, and when he finished reciting, he praised him well.

The little guy who got the compliment was happy, and said again: "Fourth brother also brought An An to write~"

After speaking, he twisted his body and got out of Kangxi's arms, and ran over to show him the words he wrote earlier.

He didn't mention the word Kangxi and almost forgot it. After reading the few words he handed over, he said, "Have you finished the words I asked you to write?"

Hearing this, Cheng An couldn't help but clasped his little hands together. After looking around with his dark eyes, he suddenly ran over to fetch the teacup on the table.

"Ama, would you like some tea?"

Kangxi looked down at the well-behaved little guy in front of him, took the teacup in his hand and took a sip.

Before the little guy who thought it was all right had time to laugh, Kangxi raised his hand and poked him on the forehead after drinking the tea and put down the cup: "Tell me, how much did you write?"

"What?" The little guy took two steps back following his strength, with an innocent expression on his face.

"Don't pretend to be stupid." After Kangxi finished speaking, he suddenly had a guess, picked up the few words just now and said, "It took so long for you to write these words?"

The little guy hung his head and said nothing, obviously acquiescing.

Although Kangxi didn't take this little punishment of him to heart, he was still a little angry when he learned that he only started writing today, and it was obvious that Yinzhen came to ask him to write.

"An'an will start writing right away, Ah Ma, don't be angry, okay?" Cheng An found that he was unhappy, and immediately rushed over to hug him.

The little guy did what he said, and he was really ready to write after he finished speaking.

However, he was going to have lunch soon, so Kangxi was not willing to let him write on an empty stomach, so he stretched out his hand to take him back and said, "Forget about today, and start writing ten words for me every day from tomorrow."

"Ama, you are so kind~"

The little guy didn't really want to write, and he rubbed happily in his arms when he heard his words.

Yinzhen was not a professional translator after all, and the books he brought back were eventually taken by Kangxi to someone to translate.

At the same time, Kangxi attached great importance to the Ruyi Pavilion he had built, and began to consciously recruit useful talents into the museum, which meant that the Ruyi Pavilion was similar to the Royal Society of Great Britain.

Days passed by, and it was February in a blink of an eye. Cheng An, who felt like he hadn't seen his tenth brother for a long time, couldn't help but start talking.

Kangxi was busy studying recently, when he saw Yin'e mentioned, he glanced at him lightly: "Have you read the book? Have you written it?"

For his sake, Kang

Xi's punishment of Yin'e before was regarded as a light punishment, so naturally he didn't want to hear him keep mentioning Yin'e.

It's still morning, so the little guy is naturally not so active in reading and writing.

Seeing him shaking his head, Kangxi said, "If you haven't, hurry up."

Seeing that his expression was quite serious, the little guy immediately turned around and ran out: "I'm going to study with my second brother!"

Compared with Kangxi and other elder brothers, Yinfeng spent the most time on enlightening the little guy.

It's not that Kangxi didn't want to teach the little guy himself, but he thought it would be good for Yinreng to have something to do, so he didn't interfere too much, and only occasionally taught the little guy.

Xian'an Palace.

Yinreng was in a good mood when he saw the little guy coming, so he directly led him into the study.

"Second brother, An An misses tenth brother."

After entering the study, Cheng An didn't sit behind his exclusive small desk, but stretched out his hand for Yin Reng to hug him.

Counting the days, Yinfeng bowed his head and said to him, "He will come to see you in a few days."

"Can An An go to Brother Ten?"

"No, Huang Ama will not agree."

The little guy was a little disappointed, but then he became strange again: "Why doesn't Brother Ten live in the palace?"

"Your tenth brother has his own home." Yinfeng patted his head and said.

"Isn't this the home of Brother Ten?"

"It's okay, but he's living at home outside now."

After Yinreng answered his few questions, he began to take him to read.

The little guy is smart but smart, but he is still young and can't sit still easily, so Yinfeng always teaches him for a while and then takes him to play for a while.

That's the case, while the little guy was studying, he had to insert a few off-topic words from time to time, such as "Why hasn't Brother Fourteen come back?" and so on.

Seeing this, Yinreng couldn't help but think of Shangshufang's 120-time reading method, and wondered whether he would be able to adapt by then.

But he is still young, maybe it will be good after waiting for two years?

Yinfeng thought uncertainly.

At the beginning of April, Yin'e finally lifted the ban. After taking a bath and changing clothes with a sense of ritual, the first thing to do was...to pay respects to the Queen Mother and Kangxi.

Of course he wanted to be the first to see Cheng An, but the etiquette cannot be waived, so he could only bite the bullet and go to see Cheng An first.

It's okay to go to the Queen Mother. After a few months, the Queen Mother didn't say anything about him.

But when seeing Kangxi, Yin'e became nervous unconsciously.

No matter what Yin'e's personality is, he definitely really likes Cheng An as his younger brother. It is precisely because of this that he has also reflected on it during these days in the mansion.

Thinking that the little guy flew directly to a place as far away as Great Britain because of a word he said that day, and everything would have been unknown if Brother Nine hadn't been there, Yin'e felt very regretful.

Probably thinking about it every day and dreaming at night.

He then had a dream, in which there was no Yinzhen, only he and the little guy went to Great Britain together, they almost didn't starve to death when they couldn't speak the language and had no money, and the most terrible thing was that they even encountered someone who wanted to snatch the inheritance. Ann's bad guys... Fortunately, at the critical moment, the little guy finally turned into a dragon, but they didn't know the direction to go back, and ended up living on a deserted island...

Yin'er is also really an emotional person. When he woke up from the dream, thinking of how miserable the little guy was with him, even knowing it was a dream, he couldn't help but shed two tears, and then vowed to think through his mind before speaking next time. .

Probably because he had reflected deeply, instead of dawdling at home, Kangxi saw him after a few months, but felt that he was a little more stable.

Even so, Kangxi still beat him a few words before letting him back down.

Yin'e secretly breathed a sigh of relief, and finally could go to see Cheng'an after bowing and leaving.

"Brother Cheng'an misses you so much!"

When the little guy saw him, he was about to speak but he took the first step. He waited until he hugged him in time before he said, "An'an misses brother ten so much!"

Seeing their appearance, which they hadn't seen in hundreds of years, Yinzhen couldn't help shaking her head slightly.

After expressing his longing, Yin'e looked down and saw that the little guy's face was plump, not at all like the skinny one in the dream, so he finally felt relieved.

"Go tenth brother, An An will take you to play~"

The little guy finally saw him and dragged him out excitedly.

"What are you playing?" Yin'er's tone rose, apparently in a good mood.

After arriving in the imperial garden, Yinzhen probably guessed what the little guy wanted to play, and immediately found a nearby pavilion to sit down, and showed with actions that he would not participate.

The little guy even specially asked him to come out, and when he saw that he was not playing, he raised his head and shouted to the sky: "Baibai—"

As soon as he finished his voice, a handsome sea dongqing fell from the sky.

Yin'er recognized that this was the crinoid that was brought back from Tibet before, and couldn't help boasting: "Cheng'an has raised this crinoid really well."

"Baibai is amazing, and he will help me deliver letters to my eldest brother and fourteenth brother~" the little guy told him with his head raised.

Costin's ability to recognize the way is not bad, especially since it comes from Tibet.

Yinti and Yinzhen were very pleasantly surprised when they received the first letter from it, and then they moved to Ganzhou and deliberately took Haidongqing with them to let it remember the new place where it was before sending it back to Beijing.

"You know that you miss elder brother and fourteenth younger brother, why don't you want them to send me a letter?" Yin'er's tone was sour.

"Brother said that Brother Ten will come to see An An soon." The little guy was still a little unhappy when he saw him. He put his arms around him and coaxed him a few words before saying, "Brother Ten, don't be angry, An An will play with you~"

"Why are you playing with me?" Yin'e pinched his face, and finally didn't bother with him anymore, "Tell me, what are you going to play with?"

"Play An'an and don't let it be caught in vain~"

what is this?

Yin'e was a little puzzled, but when Hai Dongqing attacked him, he quickly understood what kind of game it was.

"Why are you chasing me! I never heard that Hai Dongqing cannibalize..."

"Brother Ten, don't be afraid, An'an will protect you!" the little guy said while spreading his hands in front of him to prevent Hai Dongqing from attacking him.

Obviously, this is a game that the little guy came up with based on Hai Dongqing catching Yuanyuan before. The human Hai Dongqing played with him for a long time, but it would not hurt anyone.

But even knowing that it won't hurt people, being attacked by this kind of raptor is still quite scary. Anyway, other elder brothers are unwilling to play this game with the little guy after trying it once.

"Cheng'an, hurry up, hurry up, block it, ah, it's coming..."

"I'm coming, Brother Ten, don't be afraid!"

"Chirp—"

Pavilion.

Seeing that Yin'e was having a good time after getting used to it, Yinzhen couldn't help but stroke his forehead with his hand, feeling that she really underestimated him.

After the game, Yin'e and the little guy were covered in sweat, but the Costin looked very energetic.

After Yinzhen ordered someone to feed Hai Dongqing some meat, he wiped the little guy's sweat himself.

Probably because he was used to taking care of him in Great Britain, and he also took care of the little guy subconsciously after he came back.

"Wipe it for me too." Yin'e moved her head closer.

"Go away." Yinzhen pushed his big head away in disgust.

Yin'e hummed lightly and said, "I'm your younger brother too, what's wrong with me?"

"I'll wipe it for Brother Ten!" Hearing what he said, the little guy picked up the handkerchief Yinzhen put on the stone table and raised his hand.

Yin'e didn't dislike that it was the handkerchief he used just now, leaned his head towards it, and said while enjoying it: "It's better for Chengan to treat me well."

"Can you act like an older brother?" Yinzhen gave him a sideways look.

Yin'e didn't care about his words, but instead said: "You just envy Cheng'an for treating me well."

Resting in the pavilion for a while, waiting for Haidongqing to fly away, the three brothers wandered around the imperial garden again.

After not seeing each other for a few months, Yin'e noticed that Yuanyuan had rounded again, and subconsciously wanted to say, I don't know if such a fat sheep is delicious.

But he thought that Cheng An liked this sheep very much, so he held back the words after a while.

After Yin'e's ban was lifted, the little guy was so happy to have another person who could play with him.

At the end of April, Kangxi moved to Changchun Garden. Obviously, the little guy's birthday will probably be spent here this year.

The reason why Kangxi came to Changchun Garden before it was so hot was naturally because it was more convenient for him to study Western learning here.

These days, he not only studied the books brought back by Yinzhen by himself, but also brought Yinfeng, Yinzhi and other elder brothers with him from time to time.

Kangxi was getting old, and his energy was not as good as when he was young, so he told his sons to study hard, especially Yinzhi who participated in the compilation of the book.

Yin Zhi participated in the compilation of the book titled "The Origin of the Law and Calendar", which is a series of books covering astronomy, mathematics and music theory.

The part about mathematics is called "The Essence of Mathematics", which was compiled under the guidance of Kangxi.

Kangxi originally thought that "The Essence of Mathematics and Physics" was already the most profound mathematics today, but now he found more than that, so he naturally had to study it again.

Because of Kangxi's attention to Xiyang, the brothers are all busy.

Yuanmingyuan.

The retainers in Yinzhen's mansion found that their grandfather seemed to be in trouble, so they naturally wanted to help him out.

"Fourth Lord, could it be that the emperor has given you some trouble?" Dai Duo asked.

While speaking, he was thinking quickly in his mind, thinking that his father had never shown such a dignified expression when he settled the debt owed by the household department, what kind of problem would make him so embarrassed.

Yinzhen nodded slightly, and handed over the real problem in his hand.

Dai Duo thinks he is a smart person, but when he saw the content on the paper, he felt like a fool.

"Dare to ask fourth master, what is it on paper?"

"Huang Ama gave me a math problem." Yinzhen had an expression of knowingly asking, "Maybe you understand?"

Dai Duo shook his head. Seeing his disappointed expression, he immediately said that he could go down and study.

Yinzhen didn't refuse and asked him to copy a copy.

Not only Yinzhen, but other elder brothers also received the math problems assigned by Kangxi, and suddenly felt that this was even more troublesome than a major event in the court.

Now Yin'er is not happy about the lifting of the ban, but instead said: "If I knew this, I might as well continue to be locked up."

"You are locked up and it doesn't affect you to do the questions. Do you think Huang Ama won't let people send the questions to your house?" Yinzhen pointed out his innocence.

"It's too difficult. I can't even read it. I should have thrown away the box in my hand when I came back!"

Yin'e thought that her recent pain was all caused by the books she brought back from Great Britain, and felt that she was a fool for still clinging to that box.

"After the emperor Ama found out, he could just throw you away." Yinzhen said coolly.

Until the day of Cheng An's birthday, the elder brothers finally had a day off in his favor.

The child grows when he sees the wind, and the little guy has grown taller now, wearing the new clothes that Kangxi ordered someone to make for him, as exquisite as a fairy boy who fell from the sky.

The little guy especially likes to celebrate his birthday, not only because he can receive gifts, but also because he thinks it will be a very lively day, and everyone will come to accompany him.

"Is Cheng An happy today?"

When watching a play after the banquet, Yin'e put his arms around him and asked.

"Happy, I want to celebrate my birthday every day~"

"Brother Ten also wants you to celebrate your birthday every day." Yin'er's tone was very sincere, after all, he could also relax when he celebrated his birthday.

Yinzhen didn't know what was going on in his heart, so she stretched out her hand to take the little guy away from his arms, so as not to be spoiled by him.

"Why does Cheng An want to celebrate his birthday every day?" Seeing Yinzhen hugging him, Yinhu asked with a smile.

The little guy raised his face and said in a milky voice, "This way my brother can play with me every day~"

When Yinhu heard this, he felt a little weak and patted his head.

"You are not young anymore, don't just think about playing." Yin Yin

Zhen Road.

Yin Zhi: "Today is Cheng An's birthday, fourth brother, don't be so serious."

Because of the little guy's words, the brothers didn't rush to leave after the show, but had a good time with him for a while.

After dinner, the little guy was playing with the gifts from his brothers, but was suddenly picked up by Kangxi.

"Ama let me down~"

The little guy hadn't had enough fun yet, and he reached out to get the gift on Luohan's bed.

"Don't want to see the birthday gift I gave you?" After Kangxi finished speaking, he had the intention of letting him go if he didn't want to.

Cheng An heard the words, but immediately put his arms around his neck and said: "An An wants to see!"

Kangxi didn't tease him either, and carried him directly to the observatory.

There is a Galileo telescope on the observatory. This is one of the gifts from Xiyang before. After Kangxi saw it, he kept it in his private treasury. It was also because he paid more attention to Xiyang recently that he was rediscovered. .

"What is this?" the little guy asked curiously.

"Telescope." After Kangxi finished speaking, he taught him how to use it.

"Ama, why can't I see anything?"

"You turn a blind eye and close your eyes."

"An'an is closed, I still can't see it!"

Kangxi was wondering that he was fine when he saw it just now, but why he couldn't see it, and when he found that he closed the eye facing the telescope, he said in a helpless tone: "You closed the wrong eye..."
