The Kangxi Imperial Ship was wide and huge, with three floors high. In addition to the elder brother, ministers, and guards, there are also bookkeepers, long-term entourage, and small servants that they can bring according to the system, and the cabins on each floor where they live are customized.

Kangxi specially ordered Mei Wending and Chen Yan's cabin to be set up near the royal car, and Qi Su Niang was also stained and lived in a cabin on the right string of the front cabin, which was connected with Chen Yan, and opposite was the cabin of the princes and the personal eunuchs and palace maids.

Starting from Jiangning, from the Yangtze River to the Cao River, along the way to Changzhou, Jiangdu, Gaoyou, Baoying to Huai'an Qinghe. It took a lot of time, Kangxi summoned Chen Yan to accompany him day and night, inquired about the control of the river, and ordered the third elder brother, fifth elder brother, eighth elder brother, thirteenth elder brother, and fourteenth elder brother who accompanied him to learn more arithmetic from Mei Wending.

On this royal ship, on the side of the Son of Heaven, there are rules for advancing and retreating, not to mention kowtowing and saluting, please say hello, it is the time to drink water and eat a meal. Qi Su Niang is not afraid of planting vegetables and feeding chickens in the countryside, washing and cooking, although it is hard to be busy every day, and there are many rules, but she can barely feel at ease, but she really can't stand these. She was taught by Chen Niangzi to understand again, and she knew that none of these things could be wrong. As long as Mei Wending doesn't call her out to check the calculations together, or summons her to Chen Yan's room once a day and personally teaches her arithmetic for half an hour, she will only be timid and stay in the room to be a female celebrity.

One day, she was making shoes for Chen Yan, and Mei Wending asked someone to call her to the front cabin. She was puzzled in her heart, and when she arrived at the front cabin, she saw Kangxi and Chen Yan pointing to the river at the bow of the boat, and there were two little princes standing beside her, she recognized them as the thirteenth elder brother Yinxiang and the fourteenth elder brother Yinzhen.

At that time, the thirteenth elder brother was thirteen years old, and the fourteenth elder brother was only eleven, the same size as Qi Su Niang, and they all stood on one side and listened. The third elder brother and the eighth elder brother in the cabin were arguing over a matter, and Mei Wending and the fifth elder brother were frowning and silent on the side.

In the past few days, Qi Su Niang has known that several elder brothers have been taught by Kangxi since they were children, and they have dabbled in both Chinese and Western arithmetic, especially the third elder brother, and he has great respect for Mei Wending. But at this time, the third elder brother and the eighth elder brother were fighting each other in front of Mei Wending, although their voices were not high, they both turned a little pale.

Qi Su Niang saw Mei Wending's embarrassed look, and knew that it was not a good thing, and her footsteps couldn't help but stop, but Mei Wending saw it, and hurriedly called: "Su Niang, you came just in time." ”

At that time, Kangxi was only forty-five years old, the third elder brother was twenty-one, the fifth elder brother was twenty, and the eighth elder brother was only eighteen. The thirteenth elder brother over there listened attentively to Chen Yan's pointing out the water shape, but the fourteenth elder brother turned his head when he heard the sound, glanced at Qi Su Niang, and then turned back.

Qi Su Niang didn't dare to look at it more, lowered her eyebrows, greeted her brothers, and asked Mei Wending, "Mr. call me?" ”

Mei Wending looked at Qi Su Niang with a smile on his face, and said in a harmonious voice: "Su Niang, the third elder brother and the eighth elder brother are arguing about the number of forces on the Gaojiayan break, which is always wrong, and one person is needed to help check the calculation, and you and the eighth elder brother are in a group to calculate them separately." ”

The third elder brother Fang saw Qi Su Niang for the first time, and saw that although she was gradually formed, she was obviously only eleven or twelve years old, and she was still a child, so she couldn't help but laugh and said, "Sir, she is the Qi family who the emperor personally ordered to drive?" ”

Mei Wending nodded, Qi Su Niang felt that the two elder brothers had won the fight, I was afraid that she was a little angry, and seeing the slight disbelief in the eyes of the third elder brother, she knew that he was quite conceited in arithmetic, no wonder people like the eighth elder brother could also fight. She thought about it again, and remembered the gestures that the eighth elder brother made at random in the poplar forest, and suddenly woke up, the eighth elder brother is not so soft as it looks on the outside, and he will not be soft at all if he wants to do it, no wonder the two of them can stand up.

She saw the eighth elder brother waving and smiling at her, so she walked over, and the four of them were divided into two groups, each according to a table, and checked by themselves.

Qi Su Niang saw that Mei Wending was here, but she couldn't say a word, so the governor had something wrong, so she didn't rush to check it, but only carefully looked at a few sets of numbers on the paper. The eighth elder brother didn't urge her, and sat leisurely on the side to enjoy tea.

Although Qi Su Niang did not investigate on the spot, she was very familiar with the formula to be used to calculate the force, and at this time, she only had a set of these numbers, so she knew that there were errors and omissions. She didn't want to say it, but when she saw the water shape map of Gaojiayan on the table, she knew that it was the actual evidence of Gaojiayan that broke the embankment on paper. She lost Qi's parents in the flood, suffered a lot, almost sold herself into slavery, and saw a lot of tragic conditions of the victims who drowned, starved to death, and froze to death. ”

When the eighth elder brother heard this, the smile on his face deepened, Mei Wending was surprised, and exclaimed: "That's right, the old man was also suspicious, and the eighth elder brother also meant the same, but he was not as sure as Su Niang. The data of Gaojiayan is the most important place for the emperor to investigate this time, and there is no room for error. ”

The third elder brother and the fifth elder brother raised their heads and looked at each other, the fifth elder brother had a calm face, but the third elder brother was quite unconvinced. At this time, Kangxi walked in and said with a smile: "Don't say whether it's right or wrong, I must go to Gaojiayan in person, and I can know the truth immediately." He turned his head to the thirteenth elder brother and the fourteenth elder brother who were following him and said: "The Qi family is the same size as you, Chen Bianzhi's mother only taught her for half a year, and then she took books as her teacher, and her academic attainments are especially above your brothers." You must remember that God rewards hard work, and you must not slack off. Yinxiang and Yinzhen responded in unison.

Qi Su Niang's heart was shocked, the management of the river is a major matter of life, and she specialized in the supervision of bridges and dams in her life, although she does not know how to govern the river, but she is very familiar with these related calculations. She is covering it up again, and when she encounters evidence that she knows is wrong, she really can't ignore it with her conscience, and the flaws will inevitably get bigger and bigger. Mei Wending prefers Chen Yan, and he prefers her even more, but it's okay. Kangxi and several elder brothers were not suspicious.

Qi Su Niang peeked at the expressions of several elder brothers, and secretly pondered for a while, suddenly suddenly. One is that arithmetic is originally about some talents, and the other is that she is not a little folk girl, how can it be worth the attention of nobles? The third is that although these brothers practice arithmetic, they still focus on scripture and political strategy, horseback riding and bow shooting, and the time spent on arithmetic must be short, so Kangxi took the words "God rewards diligence" as an encouragement. But she didn't know anything except arithmetic, so it's no wonder they weren't suspicious.

Qi Su Niang secretly breathed a sigh of relief, after she came to this world, how could she not regret that she was too partial to study in her previous life, and her knowledge of literature and history was all about coping with the exam and losing it after swallowing dates, and if she had leisure on weekdays, she would rather watch urban soap operas. For the things in this world, except for knowing that Kangxi has a long enough life and is famous enough, he doesn't know anything else. Now, it seems that such a blind eye is not a blessing.

Just look at a powerful eunuch like Li Quan'er can understand, these days the nobles are all shrewd, she is an orphan girl from a poor family, and she can't remember her parents with a stupid head, if everything is known, the flaws will be revealed unconsciously, and it is inevitable that people will not see the problem. After studying arithmetic, she knew that pretending to be stupid was a difficult technical job, and she really didn't have much confidence.

Qi Su Niang was secretly glad that the third elder brother heard that Kangxi was going to be in danger, and said: "Huang Ama, the Gaojiayan breach is huge, and it has not been blocked so far, and there is danger from time to time, my son is willing to inspect the water shape on behalf of Huang Ama, and I also ask Huang Ama to take care of the dragon body." ”

Kangxi shook his head and said: "Since I ascended the throne at the age of eight, I have known that the Huanghuai water is dangerous, and I have been studying the matter of river control since that year, but it is still careless. During the second southern tour in the 28th year of Kangxi, he knew that if there was no accurate evidence, the so-called methods of blocking, leading, blocking, and leaking could turn benefits into harms. After returning to Beijing, he asked priests to teach me the arithmetic learned in the West, and now I have not known it for ten years. The stakes are too great for me to decide. With that, he waved his hand and ordered everyone to stand back.

Qi Su Niang slowly walked back to the cabin, heard the footsteps afterwards, turned her head to look, but it was Chen Yan who chased after her, secretly handed her a paperwork, and whispered: "You take it well." And he turned and went.

Qi Su Niang entered the room and opened it, and her heart was beating wildly, it was actually Wen's Su Niang's deed of sale!
