Qi Su Niang slowly knelt down in Chen Yan's three long live voices, watched the corners of her clothes fly in front of her, and the group entered the main room in a blink of an eye. It's just that when the eighth master of the big noble man with full flags walked in front of her, he seemed to pause, and then he also passed.

There were seven people in the room for a while, but there was not a trace of sound, Qi Su Niang and Chen Yanju changed their clothes in addition to filial piety, and asked Kangxi for peace again.

Qi Su Niang never thought that a fugitive slave like her would see the emperor one day, and she was worried. She peeked at it, and the emperor was taking a detailed look at the water shape diagram on the table, and the others didn't dare to disturb. The white-bearded old man, who had just called out to "change", his eyes fell on her, and after a careful look, he turned away.

Qi Su Niang's heart moved, knowing that this old man was what Chen Niangzi had said, such as Mei Wending, the first person in arithmetic today. Although he is not a scholar, he is highly respected by Kangxi, and Chen Yan's arithmetic is taught by this person.

"I heard Zhang Pengxi say that the water map you made is very fine, and it is more useful than the official system, so I came over today to take a look, and it is so." After a while, the emperor finally put down the river map in his hand and turned his head to look at Chen Yan, "I didn't expect you to know much about the Yongding River." ”

Chen Yan hurriedly knelt down and said: "Back to the emperor, the Yongding River is related to Gyeonggi, and it is diverted every year, and the weight of the flood is not deep, and the students dare not not investigate." ”

When the emperor heard that he called himself a "student", he knew that he was famous, nodded, and said while looking up and down: "Listen to Mr. Mei, you are only eighteen this year, but you are studying arithmetic and the way to govern the river, and it is really a family history." He turned his head to look at Qi Su Niang and said, "This woman is your wife?" Qi Su Niang heard the words "family origin", and it was expected that it was not that Chen Niangzi knew arithmetic, but that she was talking about Chen Yan's deceased father. She was puzzled, and when she heard Kangxi ask about her, she was suddenly shocked.

"Your Majesty, she is the wife of the student's mother, the Qi family. Because of the flood, her parents died, and she was helpless, so she fled so that the students took her to live with her. After the filial piety period, Fang Baitang got married. ”

The emperor nodded slowly and said, "Since she is helpless, it should be like this, let's get up." ”

The two replied in unison, "Thank you, Your Majesty." Standing aside, Qi Su Niang originally said in a suppressed voice, but unexpectedly, the emperor was extremely deaf, pouted slightly, turned his head and said, "Who are you?" Look at your appearance and accent, you don't look like a Jianghuai person. ”

Qi Su Niang had no choice but to reply: "Back to the emperor, the people's daughter was sold to Jianghuai by the Yongding River flood the year before last, but she was young and couldn't remember where her home was along the Yongding River. She also had some broken memories in her body, only remembering that there were brothers and sisters at home, but they were very vague, so she also threw them away.

Unexpectedly, the emperor didn't ask much about Chen Yan's life experience, but asked her a lot of questions. Qi Su Niang was panicked, where did she know about these past things? I wanted to make up a few nonsense, but I knew that there was a "crime of bullying the king" in this world that could kill the head, and such a small thing could be found out if it was true or false. Although he knew that the emperor didn't have the time to check her, he didn't dare to leave a bane for the future for the sake of temporary convenience. She didn't dare to lie, so she had to be vague, all under the pretext that she was too young to remember. But she is now eleven years old, and what a normal child of seven or eight years old can remember, unless she is a fool, where can she not remember? But in front of the emperor, she didn't even dare to deliberately pretend to be stupid, and she could only shake her head if she couldn't answer.

Kangxi didn't seem to expect such a scholar with "family roots" and fame to actually order a fool's wife, and he groaned for a while. Qi Su Niang lowered her head, dripping in cold sweat. Fortunately, he didn't ask again, and only ordered Chen Yan to take out all the pro-system river maps, and Qi Su Niang dared to breathe a sigh of relief and took the opportunity to retreat.

Kangxi looked at the river map, and if there was any uncertainty, he ordered Chen to give a speech. Chen Yan studied this way deeply, and he was confident and talked eloquently. Later, Kangxi specially allowed Chen Yan to express what he had seen, and the emperor asked him a difficult question, but Chen Yan still answered like a stream, and Qi Su Niang's stupid appearance of not knowing everything was heaven and earth.

Kangxi Longyan was very happy, and he didn't care that it was too late, so he gave a seat to the accompanying eighth elder brother Yinxi, the governor of Liangjiang Zhang Pengxi and Mei Wending, and asked Chen Yan to sit down together, and discussed the matter of governing the river under the oil lamp.

Qi Su Niang wiped the cold sweat on her forehead in the side room, while thinking about the "Eighth Master", a nobleman with a full flag. When she heard what Xiao Cui said, she knew that the "eighth master" was not an ordinary person, but she didn't expect it to be the prince. Now seeing him on the emperor's side, he is very favored, and he can't help but be terrified. Fortunately, she realized that she didn't see herself in half of her eyes on this day, even if she was just talking on the street, although she was rude, she didn't show any major flaws, so she was a little relieved.

She opened the door and looked up at the sky, the hourglass had passed the end of the hourglass, about seven o'clock in the evening, and she didn't know if the emperor wanted some food. Just as he hesitated, he stood motionless at the gate of the courtyard for two hours, looking at the plainclothes eunuch who was about thirty or forty years old, suddenly moved, glanced at Qi Su Niang, walked up and said softly: "Miss Qi, is there food in the stove?" ”

Qi Su Niang hurriedly nodded and said: "Back to my father-in-law, there are also the vegetable porridge and pastries that I boiled last night, if it doesn't work, I will have it in half an hour, but it is all coarse food, I am afraid that it will not be able to enter the eyes of the emperor." ”

The big eunuch thought for a while and said, "The emperor has stopped eating because the people in Huai'an have been severely affected, so you can take our family to take a look." ”

Qi Su Niang hurriedly brought the big eunuch to the stove. The eunuch saw that the stove room was tidy and the utensils were clean, and he was satisfied with it for three points, and then tasted the vegetable porridge and the dim sum that was warm in the pot, and he was also satisfied. He nodded while looking at Qi Su Niang without a trace, as if he didn't expect that such a stupid girl who couldn't even remember her parents would live a good life. The eunuch said, "That's it, the emperor is tired today, and he must be hungry." It's too late to do something new. He said, "Miss Qi, our family still has to worry about you." ”

Qi Su Niang hurriedly said: "Father-in-law, please speak." ”

"The emperor is discussing the matter of river work with Mr. Chen, and he must not be able to listen to our family's advice to eat, and ask Miss Qi to give Mr. Chen a look, and our family can do things."

Qi Su Niang smiled bitterly: "Father-in-law doesn't know, it's not Su Niang's excuse, it's really Brother Chen's thought of governing the river, even if the thunder in the sky can't be heard, where can you still see my eyes?" ”

The eunuch was stunned, and the two were working in the wax room, when they suddenly heard Chen Yan calling in the courtyard: "Su Niang, Su Niang." ”

Qi Su Niang was stunned for a moment, exchanged glances with the eunuch, hurriedly walked out, and said, "Brother Chen, I'm here." ”

Chen Yan looked excited, and said: "The emperor just asked about the method of diversion of the Yellow River, to calculate the flow of the Yellow River, although there is Mr., Lord Zhang, and Eighth Elder Brother to help, the manpower is still not enough, I know that you are literate and understand arithmetic, and ask the emperor to calculate it together." With that, he led her to the main room.

Qi Su Niang was dumbfounded, and said in surprise: "Brother Chen, how do you know that I am literate and understand arithmetic?" ”

Chen Yan said casually: "The books on my bookshelf are numbered in the number of the return, and they are all placed randomly on weekdays, but you have sorted them out at all, and I use those arithmetic books every day, and every time I see traces of turning, who else is there in this room besides you?" Don't worry, you just have to keep a count, and that father-in-law is afraid that he doesn't understand. ”

Qi Su Niang heard that Chen Yan was so careful, and she was secretly shocked, only to feel that although he was concentrating on river work, he was worthy of being Chen Niangzi's biological son, and he generally had eyesight. Now, Qi Su Niang had to follow behind him, walked in to take a look, and saw that Kangxi and several people were all sitting on the desk to check the calculation, and when she came in, she didn't realize it, and Chen Yan didn't teach her how to act, and she went to check it herself.

Qi Su Niang didn't dare to make a sound, but she didn't know what to do, so she had to stand in a daze. After a while, Eighth Elder Brother Yinxi raised his head, handed her a piece of paper, and said, "Later, I will add the numbers given to you by the emperor and several adults in the first round, add the ones given to you in the second time, and subtract the ones given to you in the third time, and then multiply the first two and divide them by the third time." Remember, don't mess around. ”

Qi Su Niang breathed a sigh of relief and nodded hurriedly. Yinxi smiled slightly, and buried himself in the calculation. Although Qi Su Niang felt that this eighth master's appearance and demeanor were outstanding. The speech was amiable, but remembering the bloody corpse in the poplar forest, his hair suddenly stood on end, and he quietly took two steps back.

After half an hour like this, Mei Wending finished counting first, Chen Yan was second, Kangxi was third, Yinxi was fourth, and Zhang Pengxi was last. Although Zhang Pengxi was the last, he was already sweating profusely. Qi Su Niang finished presenting the numbers, Kangxi and the others saw that it was really good, and they were all surprised, obviously they never thought that she, a person who couldn't even remember her hometown and family, would actually be able to study. Kangxi couldn't help but ask her who she was taught by, but fortunately, Chen Niangzi's arithmetic attainments are not shallow, so Qi Su Niang blamed Chen Niangzi all on her, only that she taught her.

Kangxi nodded slowly, "After only teaching for half a year, I can be so ......"

Qi Su Niang understood the meaning of Kangxi's words, Kangxi did not praise her for being smart, but praised Chen Niangzi for teaching a fool like her, which is not easy.

Kangxi asked, and then discussed with Mei Wending how to distribute the next part of the calculation. Zhang Pengxi listened to their discussion, smiled bitterly, got up and played: "Your Majesty, Weichen is not an ordinary arithmetic, and he can barely support the calculation, and then it is easy to make mistakes and miss the emperor's affairs." Or, tomorrow, ask the third elder brother and the fifth elder brother to help calculate it? ”

Qi Su Niang listened on the sidelines, Kangxi and Mei Wending discussed the flow of the Yellow River every second when it flows through every gate and dam, which has to be divided into sand and gravel flow and water flow, which is indeed a more complicated calculation. At this time, there is no formula that can be directly applied, and it is necessary to calculate step by step, even if Yinxi is embarrassed, Zhang Pengxi really can't support it.

She saw Chen Yan's disappointed face, knowing that he was eager to control the water, if there were only two people in the world, even if she didn't recommend herself, she would find a way to help him, where would she dare to speak out now? Qi Su Niang made up her mind and closed her mouth, but Mei Wending suddenly asked: "Miss Qi, the old man sees that your numbers are very clear and fast, and it is definitely not a day's work, what the emperor said, can you understand?" ”

The eyes of several people in the room fell on Qi Su Niang. Qi Su Niang secretly complained, she had tried her best to slow down the calculation speed, but for more than 20 years, Mei Wending was old and old, and she couldn't hide it no matter how she covered it up. Although she was covering it up, she didn't dare to let people find out that she was deliberately hiding, so as not to cause more trouble, and seeing Chen Yan's look of hope, she sighed secretly and replied softly: "Sir, if the emperor allows it, Su Niang can give it a try." ”

Kangxi is obviously also calculating the prosperity, no matter who it is, as long as the top is used, even the sound is accurate, Qi Su Niang took the opportunity to say: "Your Majesty, because the people's daughter has never heard of the cause and effect at first, I want to ask the emperor to be lenient for half a moment, let Brother Chen tell me," looked at Kangxi's face, and said: "It's late, although the poor family doesn't have much good, the vegetable porridge and noodles were all saved last night, and the emperor ......."

Mei Wending was very courteous to Kangxi, nodded and smiled: "Your Majesty, I think she is reasonable, I need to let Chen Yan explain it to her, and besides, the emperor is inspecting the river workers outside today, he must be tired, but this kind of coarse food ......"

Kangxi was actually so hungry that he didn't have time to take care of it when he checked it, so when he heard this, he called: "Li Dequan." "The plainclothes eunuch Li Dequan served the porridge and food, and the emperor gave it to everyone to share the food. Su Niang saw that Chen Yan couldn't care about eating, so she was about to say something, so she pulled him away a few steps and said with a smile: "Brother Chen, I have just heard a lot, and I probably understand, but I am afraid that there will be a mistake." Listen to me while you eat, and if you're wrong, it's not too late to say it. ”

Chen Yan hesitated, then nodded in agreement, and sold a mouthful of porridge and dried vegetables to listen to Su Niang's narration. When he finished eating, Su Niang also happened to finish speaking, and it was really the same. Chen Yan was overjoyed and said: "Yes, yes." Su Niang, you are really inferring from others and being very smart. ”

Kangxi, Mei Wending and others all chuckled, Kangxi smiled and said to Mei Wending: "Mr. Mei, your student is so straightforward. ”

Mei Wending was very relieved to see that Chen was loved by Kangxi, and said busily: "What the emperor said is that he is young and young, although he has the ambition to specialize, he will inevitably be blinded. ”

Kangxi shook his head slightly, "Specialization is extremely rare." After that, put down his dishes and chopsticks, Li Dequan came in and cleaned up, and a few people didn't need to be greeted, they all started to check, and the matter of unification was entrusted to Zhang Pengxi.

Although the calculation of the water flow cube is complicated at this time, it is not difficult for Qi Su Niang. It's just that where does she dare to make people notice? She had just seen everyone check the calculations, and she knew their calculation ability, and she didn't worry that Mei Wending could use it for two purposes, and found that she was delaying time, deliberately slowing down the calculation speed greatly, and it was only when Yinxi was half a pillar of incense late that the results were presented, which was already a great surprise to everyone.

Kangxi and several people got strong help, rushed to work overnight, and repeatedly checked the diversion of the Yellow River, to the point of extreme difficulty, the five people were divided into two groups, each of them checked, it is inevitable that there are two numbers wrong when checking, or there are different algorithms, Mei Wending is just fine, Chen Yan is also a person who does not recognize people, and Kangxi dares to top it. Qi Su Niang on the side was so frightened that she couldn't pounce on her to cover Chen Yan's mouth, for fear that Chen Niangzi's only son would anger the emperor and lose his life. Fortunately, Kangxi really remembered the same as she vaguely remembered, he was a "Ming Jun", he saw that Chen Yan was so serious about the river work, and he was not annoyed at all, but he was refuted a few words and responded with a smile. Qi Su Niang was shocked and shocked this night, and she was already sweating on her back.

When the sky is about to brighten, the cold dew is a little bit, Kangxi threw down his pen and said: "The Yellow River and the Cao River must be two-pronged, which is a long-term plan, and there are several dam gates such as Gaojiayan that have not been obtained. ”

Although Yinxi and the others were afraid that Kangxi would be too tired, they didn't dare to persuade him at this time, Zhang Pengxi took the first step and rushed to the berthing of the imperial ship to arrange it thoroughly, Kangxi strode towards the courtyard gate, and said: "Mr. Mei and Chen Yan will go with me." After a pause, he said, "The Qi family is going together." ”

Qi Su Niang quietly wiped the cold sweat in the palm of her hand on the corner of her clothes, she knew the rules of this world, ordinary women still pay attention to talentlessness is virtue, Chen Niangzi is like poetry, arithmetic, and a poor woman who understands the world is difficult to find. Although Chen Yan is her son, he is also an ordinary man in the end, and he may not like his stupid wife who has not passed through the door to go out and show up. She turned her head to look at Chen Yan, but when she saw that he heard this, her face was full of joy, and there was no displeasure, and she whispered to her: "I'm not worried about you being at home alone......"

Qi Su Niang glanced at Chen Yan, turned her head back to the house and hurriedly packed a few clothes for her, took her own baggage, and hurriedly locked the door with Chen Yan, who was holding a bunch of river maps.
