048 Xu Guangqi arrived

Sun Yuanhua originally lived in the eastern suburbs of Beijing, but later the emperor gave him a four-entry courtyard next to the two courtyards next to Dongshunmen Street, and moved his family over again. On weekdays, he and Yuan Chonghuan trained their recruits separately in the Beijing camp, and they didn't come back often. If there is a big courtyard, there is also his wife and daughter Sun Yousu, and occasionally Chen Zilong and Song Yingxing will also come over to support the affairs of the house.

Yesterday, Sun Yuanhua sent his own soldiers to pass the word, saying that he would come back tomorrow with Xu Guangqi, who went to Beijing, and that Lord Xu Guangqi would temporarily live in the courtyard next door.

Mrs. Xu had arranged for someone to tidy up for a long time since yesterday afternoon, and before midnight this morning, she pulled her throat to settle the servants to sprinkle water and sweep the streets.

"Mother......" her daughter Yousu was wearing a moon-white jacket, standing at the door of the lobby and stomping her feet and shouting.

"Daddy, even if he went to the Eighteen-Mile Pavilion early in the morning to pick up people, and picked up Teacher Tai when he returned home, it was already past the unitary time, how could you clean up every day before dawn, and let people not sleep."

"Miss, miss." Before Mrs. Xu could speak, Yinqiao, a maid about the same age as Miss, hurriedly ran out, holding a cloak in her hand, "Why did you come out in a jacket, and you are not afraid of freezing." ”

Mrs. Xu took the cloak, and then said to Yinqiao dotingly: "You still said that your young lady, look at you." Yinqiao was in a hurry, and ran out wearing only his underwear.

Mrs. Xu is an enlightened person, and while putting on a cloak for her daughter, she said: "Everyone is a beautiful girl, but you let your father spoil you." After a while, your Senior Brother Sun and Song Juren will come over, and our family will have no rules. ”

Mrs. Xu is also religious, and the two of them are restricted by the rules of the church, and there is no concubine, and there is only one child, Yousu. Since childhood, he has studied Western studies with Xu Guangqi and his father, and also studied Chinese medicine with his mother.

At noon, Chen Zilong and Song Yingxing also arrived with the drunken and Chun cook. A few people were talking and laughing when they heard the sound of a carriage outside the door.

"Dad and Master Tai are here."

The boy didn't see his father a few times a month, so he rushed out happily when he heard the voice. Seeing Xu Guangqi who had just gotten off the carriage, "Thank you, Teacher Tai, for thinking about Yousu, and Yousu kowtowing to Teacher Tai." ”

After that, she knelt in front of Xu Guangqi's knee and kowtowed three times. Teacher Tai is not as serious as his father, and he always sends her some good things on weekdays, so she prefers Teacher Tai, and Teacher Tai also dotes on her the most among the disciples. Like this time, Chen Zilong and Song Yingxing were just standing in the distance to give a salute, watching the little junior sister holding Teacher Tai's arm and coquettishly.

Xu Guangqi stroked his beard and looked at this female doll with pink makeup and jade makeup and smiled from ear to ear.

"It's done, Daddy still has something to tell Teacher Tai, you let go of your hands first." Sun Yuanhua patted her hand, "The gifts that Sister Martina and the teacher brought to you are all in the carriage behind. ”

"You Su doesn't care about any gifts," she said, looking behind her, and seeing that everyone was laughing, she said, "Aren't people thinking about Sister Mar?" ”

Martina is Xu Guangqi's youngest granddaughter, and the old man has been taking him with him lately. Getting off the bus with Mardina was Xu Ji, the eldest son who accompanied his father-in-law Gu Changzuo, Gu Changzuo was not in good health, and he was out of breath all the way.

Several people have met, Mrs. Xu took her daughter to help her son settle Gu Changzuo to rest, and Song Yingxing settled Tang Ruowang. Sun Yuanhua hurriedly invited Xu Guangqi and Chen Zilong to the study to talk.

Sun Yuanhua was the only person who had dealt with this emperor, and he also knew how much this emperor did not follow normal rules. Other emperors want to meet with ministers, and there are a lot of processes, and it takes four or five days to get a good lineup. But this one is different, maybe he will come over in a while.

Taking advantage of the time when Sun Yuanhua went out to settle down for dinner, Xu Guangqi flipped through the two pamphlets on his desk. The names of both books are easy to understand, one is called "Training Manual" and the other is called "Mathematical Simplification Symbols", and next to them are a pamphlet bound on white paper and two strange pens of red and black colors.

Sun Yuanhua came in and saw the teacher holding two pamphlets flipping through them, so he smiled and said:

"This is also the reason why the students are not considerate of the teacher's long-distance fatigue, and the previous students have already given the previous version of the booklet to the teacher, what do you think?"

A few days ago, Sun Yuanhua couldn't hold back his mood, so he asked his relatives to quickly send the first two books to his teacher, and now the two books on the table have added some new content.

"The old man was puzzled." Xu Guangqi scratched his white hair. "You are better at training than the old man, but this old man in mathematics is in charge. If this is really the experience of His Majesty today, it can only be said that God bless the Ming. ”

Not long after, Song Yingxing also came in, Xu Guangqi originally wanted to call Tang Ruowang over, but was stopped by Sun Yuanhua.

Sun Yuanhua took out the ruler, triangular ruler and compass handed over to him by the emperor a few days ago. According to the emperor's usage, the usage was quickly demonstrated. And it was marked with the so-called Western letters and numbers that the emperor had taught. Obviously, it is much faster and clearer than my teacher's use of traditional Zi Chou Yin Mao to mark the geometric originals of the translation.

Song Yingxing quickly indulged in it, Xu Guangqi was an official after all, suppressed his surprise and interest in these, and forced himself to sit down and drink tea before asking:

"The teacher is a little upset, you tell me what you know about the current majesty."

Sun Yuanhua had never seen his teacher behave so badly, and while thinking about it, he said slowly:

"A hammer in the east and a mallet in the west. I understand everything, and I can pick up the secrets of any family. There is no portal view, and there is nothing hidden and tucked. ”

Sun Yuanhua pointed to the tools on the table:

"The last time I saw this on His Majesty's desk, I was also amazed. The emperor didn't hide his secrets, so he showed me the method of bisecting the circumference, and marked the symbols while doing it. I don't understand either, but this is another lesson, and I explained the use of symbols to me and Inspector Yuan Chonghuan for most of the night. ”

"The next day, the minister sent me these tools. I took the time to compile what His Majesty said into this booklet, and the emperor was very happy to see it, and he revised it for me with a pen. "Sun Yuanhua opened a cabinet with a lock, took out the version of the booklet that the emperor had personally modified, and handed it to Xu Guangqi." I don't understand some of them, and the emperor said that the teacher will come in the future. ”

"So the emperor is better at Western mathematics than Mr. Xu?" Chen Zilong, who was listening, asked curiously. In his heart, he really has never seen an emperor who is good at learning.

"I can't say it, it feels like it's been simplified a lot, like I learned it directly from Western books."

"The key is that the emperor knows more than this, for example."

As he spoke, Sun Yuanhua unfolded a blanket on the ground that was spread on the soft collapse of his study. In the puzzled eyes of everyone, he spread the blanket on the ground, squatted down, and folded the blanket into a boxy piece with sharp edges and corners. Next, tie a long strap with a quilt behind you.

"Your Majesty will also sort out the methods of these women?" Chen Zilong didn't understand, and asked a little frivolously.

Sun Yuanhua said to him: "I must recommend you to Your Majesty when I go back, Zilong must be cautious in his words and deeds." After finishing speaking, he turned to his teacher Xu Guangqi, and saw that Xu Guangqi was confused, so he explained:

"The students were just like the teachers. The emperor asked me to persevere in the 500 new army. But it's only been a month, but I've seen the changes in these big-headed soldiers, I can't say it specifically, it just so happens that the research institute that focuses on firearms outside the country Zijian that the emperor said is together with the Royal Army Academy, and the teacher is also free to meet. ”

"Royal Army Academy," Xu Guangqi wrote these words on the paper, and then pointed to Sun Yuanhua and said: "Yuanhua, these words don't look like they came from the ancient books of the Ming Dynasty, but more like they came from Franco?" ”

A few people were chatting, and there was a sound of kneeling outside the door, and several people looked at each other and hurried out.

I saw that the front yard was already kneeling, and a young man wearing an official school uniform marked with a black dragon pattern walked in stride, and said as he walked:

"Get up, and don't kneel once. I heard that Xu Guangqi had arrived, so I came over to take a look. ”
