Fall in love with the technology tree [Three Kingdoms]

After getting Uncle Ding's promise, Ah Sheng felt like a Buddha, sitting quietly in his seat thinking about his next plan.It wasn't until the tea and snacks were exhausted that she stood up in a daze, and followed the others to the banquet hall, where lunch should have been served.

A little Douding bumped into him just at this moment, and if Luo Chi hadn't blocked him, he would have almost bumped into Ah Sheng, who hadn't noticed his surroundings because he was distracted.

Xiao Douding was pulled away by Luo Chi, and knelt down on the ground: "Father, I want to read."

It is Cao Yu.

If he hadn't been able to meet during the New Year's ancestor worship, Ah Sheng would have almost forgotten this brother.

"Ayu? What are you doing weird in front of the guests?" Cao Song shouted.

As soon as Cao Song drank, the wet nurse and Yin Shi who rushed out from behind also followed with a "plop" and cast their bodies on the ground: "Your Majesty, calm down."

Cao Yu is two years and one month younger than the twins, and is now six years old, and looks white and tender.He bit his lip, not daring to answer his father's words, but held back his tears and raised his head, his eyes full of anticipation.

Uncle Ding and Cousin Ding were embarrassed at this time, because they encountered other people's housework.Although the Yin family used to be the servant of the Ding family and the dowry of the Ding family, she is now Cao Song's concubine.According to the established etiquette, the Yin family, Cao Yu, and the Ding family have no relationship at all, just like the Zhang family has no relationship with the Zhang Wen family.

Cousin Ding took a step aside: "Why don't I go ahead with my father? It's enough to have a servant to lead the way, and my father knows the way." She is not in her position and does not plan for her own affairs. She is very organized and does not mess up when things happen.

Uncle Ding quickly agreed: "Jugao, you take care of your housework first, and Cheng Ji and I will go to the banquet hall first."

Cao Song was very embarrassed: "I'm sorry."

When the guests left, Hu took the lead in attacking: "Yin, what do you mean? I have never been short of you for food and clothing, but it was because of the opening of Meng that you were evaded for two days because of filial piety, and you gave up in front of the gentleman and the guests." I'm ashamed?! That's fine! I can't control this matter, let your husband decide for you!"

This is the end of her words, Cao Song must protect the dignity of his wife: "My maidservant has a son, what characters do you recognize? Jili and Ruyi haven't had a teacher for three years. If you want to find a teacher, you must first follow your son."

Yin fell on the ground and did not dare to raise her head: "Mr. Lang, Madam, please be kind to Ayu."

Cao Song waved his hand annoyedly: "It's also my flesh and blood, what would I do with a child? Since you can't raise a child and let him cause trouble, then don't raise it. Send Ayu to the main courtyard today."

Hu: "I don't want it!"

Uh... Ah Sheng and his brother looked at each other, and his mother was obviously angry.Hu has a straight temper, it is best not to confront her at this time.

Mrs. Hu sneered: "I think it would be good for Ayu to be raised in the maid's house." Worse than a decent servant.

Yin Shi lay on the ground and shook, even if she couldn't see her face, one could imagine that she was crying. "The maidservant's life is so cheap... It hurts Ayu... It makes Lang Jun feel ashamed..."

Hu's nurse, Chang, saw that things were stuck, and hurriedly stepped forward to remind her: "Mr., madam, the Ding family's guests are still waiting in the banquet hall."

Cao Song slapped his forehead. "That's right, that's right. Come here, send Yin's mother and son back to the room, and stop for a month to reflect on your mistakes." He then coaxed Hu: "Let's go first, don't let the Ding family see the joke."

This little storm has come to a conclusion.

Only then did Cao Yu regain his composure, kneeling on the ground and crying loudly.From the beginning to the end, no one cared about the matter of "he wants to be literate".

Ah Sheng also regretted it later. At that time, her mind was completely occupied by the Hainan Island project, and she did not devote her thoughts to the out-of-school children and the mothers of out-of-school children.

That night, Yin was hanged on the beam of his room.

"This... is this dead?" When the news came, Hu's hands trembled, his face turned pale, "I just reprimanded her a few words? Why did she die?"

Guilty and guilty, she arrived at the scene, glanced at the corpse and looked away.

At the end of winter and the beginning of spring, the weather was still cold, and there was no brazier in Yin's house, so the body was already chilled.Cao Yumu knelt on one side in a daze, with a dull expression, he didn't know whether he was frightened or frozen.Because even when the Yin family was restrained, he didn't respond at all when Cao Song called him, so everyone said that Wu Lang was probably stupid.

It is very unlucky for the masters to die just after leaving Xiaoqi's house.Under the persuasion of several sisters-in-law, Hu asked alchemists, Taoists, witches and the like to come to the house several times to remove bad luck.She didn't really believe this at first, but since Yin's death, she has been haunted by nightmares, and she can only be a dead horse as a living horse doctor.

Since Hu married into Cao's family, there has been no mistake. Until this incident, it is possible to say that she treated her concubine harshly and forced her to commit suicide.That's why it bothered her so much.

A Sheng was also worried about this.

"Asheng, aren't you going back to the other courtyard today? Why did you stay for an extra day? Because of Ayu's mother?" Cao Cao asked her.

A Shenghu sat on a big rock outside Cao's residence, resting his chin on one hand imitating the "Thinker" sculpture: "Why did A Yu suddenly run out?"

Cao Cao spread his hands: "Probably someone provoked it. The Yin family is stupid, or someone wants to harm the Yin family. Who knows? In short, it has nothing to do with us."

"I still remember how she picked up leaves in her mother's yard with her big belly. After all, there is some old friendship. I thought she was luckier than my mother, and gave birth to the child safely, but I didn't expect that she still couldn't escape a 'death' 'Character."

Cao Cao broke a newly grown dogtail grass from the side. "Does she deserve your sympathy for her own death? Did she think about Ayu's feelings when she wanted to die? Even if she is dragged down by her biological mother, as a child, she still wants her mother to live."

"Eh? Did I say that she committed suicide by herself?"

"Eh?"

"Ms. Yin was hung up after being strangled to death. The strangle marks on her neck came to the back, but mother and father didn't check carefully. They wanted to expose this matter as soon as possible."

"That……"

"Ayu lives next door to the Yin family. If he saw it, it would be even more pitiful."

Cao Cao's face darkened: "Someone in the family sneaked into the house late at night to kill someone? You can't keep this kind of person! Are you looking into it? If you don't look into it, I will look into it!"

"Then brother, let's go and investigate, just to get to know the woman's pathetic tricks." Ah Sheng had a complacent expression on his face, "I've been dizzy for the past two days, so I won't get involved."

With Cao Song's filial piety, the house fight also kicked off again, which seems to be an inevitable thing.But just like Cao Cao said, no matter how much they fight, they dare not easily touch the son-in-law who is surrounded by loyal servants.There is no danger, but Cao Cao is not very happy.In his simple concept, both the murderer and the messenger should be judged with justice.However, in fact, except for the bottom executioner, he couldn't get more results he wanted.

When Cao Cao dragged Ayu to the other courtyard, Asheng was teaching the "first-year students" in person, talking about refraction of light paths, the use of sextants, and the measurement of latitude and longitude.Students who have only studied elementary school mathematics for three years are confused by trigonometric functions.

"If you have any questions, just ask them."

Twenty Seven raised his hand hesitantly. He was almost 14 years old, and his height began to increase rapidly. Coupled with his strong muscles, the seat seemed narrow.But no matter how strong and healthy he is, he still has to give up in Ah Sheng's class.

Ah Sheng wiped his chalk-stained fingers: "Twenty-seven."

"Master, is the earth really spherical?"

"I don't care if it's spherical or not, and it doesn't matter what the book says. You can only know if you measure it yourself."

"Oh... the person under the ball... won't fall?"

"There is heaven and earth first, and then there is up and down. You and the people on the back of the ball think that the direction of the sky is up, and the direction of the earth is down. As for the earth itself, it is suspended in the void and wrapped in air, and there is no distinction between up and down. "Ah Sheng spread his hands, unable to bear to look at the children's shattered eyes.Today's class must be beyond the outline, and she speaks relatively fast, presumably most people can't keep up.But her purpose is not to teach, but to select children with good geography and geometry talents as one of the first candidates to be sent to Jiaozhou.

On the space exchange day last year, she got a map of the distribution of major minerals across the country.Although a bit rough, the accuracy absolutely beats the military maps of the Eastern Han Dynasty in the same period.With the map, there must be a surveyor who can determine the latitude and longitude for prospecting. The Ding family will provide a guide who is familiar with the southern customs. servant.In the end, there must be a diplomat who can handle the scene and deal with the rich.

Speaking of diplomats, Ah Sheng thought: "Kong Mo."

"No, no. I'm here." Kong Mo suddenly raised his head from the pile of draft paper, "Master, I also think that what Hun Tian said is more reasonable than what Gai Tian said. Look at the carriage coming from afar, The canopy is often exposed first, which is a proof that the earth is arc-shaped. And the earth revolves around the sun, which perfectly explains why there are four seasons. If the lunar eclipse revolves around the earth, then both solar and lunar eclipses can be Calculated!" The more he said, the more excited he became. "I'm going to make an 'all-sky sphere' to ensure that it can measure the astronomical calendar, which is more accurate than the armillary sphere!"

The students were too enthusiastic, and Ah Sheng was speechless. She was not used to such a "modern" science madman as Kong Mo.

"Carpenter Ai?"

Carpenter Ai nodded: "Understood. Does the master want more sextants? There are still some small pieces of flat glass left."

Yan Wen, who was sitting in the last row of the classroom, raised his hand: "I also understand. I have some new ideas about terrain sketching, please correct me, Master."

"Where's Mrs. Liu?"

Mathematics teacher, southern native, Mr. Liu hated his colleagues for half a second, and then decided to tell the truth: "I don't understand."

"Okay, Kong Mo, you will take the lead and be responsible for teaching everyone the method of latitude and longitude measurement. Tomorrow I will talk about the earth's magnetic field and map drawing. get out of class is over!"

Ah Sheng left the students who were still in a dazed state, and ran out the door. "Why are you here, brother?"

Cao Cao stroked his chin: "Ah Sheng, is the earth really a sphere?"

Ah Sheng: ... "Hey, it doesn't matter if it's round or not. When you can lead troops to fight, I'll keep and send you a few technical soldiers who can draw maps. Why did you bring Ah Yu here?"

My sister didn't want to go into details, and Cao Cao didn't bother. He really stayed away from the scientific research work in other courtyard workshops.

Although Cao Yu was dumbfounded, his gaze was fixed without any dodge: "Second brother, I want to learn how to read and write."

"This...you should find your parents..."

"They won't teach me!"

"Ayu..."

"Second brother, I'll sign a contract for you, let me study."

Don't talk stupid things, no matter how low the status of the concubine brother is, can he really be used as a servant?It is no longer the pre-Qin period when the status of children followed their mothers.A Sheng said with a serious face: "You are not allowed to mention the matter of body deed, it is inhumane and unreasonable! Besides, I don't have time to give you counseling. If you want to learn, you have to hide your name and work with the servants. What you learn is not traditional. The Five Classics are useless for an official."

Cao Yu's eyes widened slightly, and Ah Sheng could almost see the light of hope in them: "Second brother, I'm learning with the servants. I just want to learn. Learn... the earth is a ball."

It is also fate to be able to speak here.The twins looked at each other, and the matter was settled.

"Brother, you will really cause me trouble. It's easy to talk about other things, but it's hard to explain to my mother."

Cao Cao laughed, brought tea and water to his sister, and apologized.

Mrs. Hu didn't care what Cao Yu learned at all, but the twins covered up and offended her concubine, which made her feel uncomfortable: "Erlang said that he will start teaching that kid in September. There is a buffer of half a year, and I still take care of my face. But I I always feel bad. I don’t know if Dalang Erlang will be able to take care of my child when he is born.”

Chang babbled while reciprocating to her: "After all, it's not my own. Madam still wants to have her own child!"
