"Hehe, Master Ma laughed." Su Lun smiled at Ma De, asked Luo Xin for another greeting, and then said: "The master, the uncle, and the sixth master are in the Deqing Building over there, and when they saw the adults and Xingge shopping here, they asked the adults and Gege to go over to talk about it. Two ...... Please! ”

"Uncle? Sixth Master? Ma De understood who these two people were after a little thought, and the ones who could make Su Lun call him the uncle and the sixth master were naturally Kangxi's eldest brother Prince Yu Fuquan and sixth brother Prince Gong Changning.

"Why is the master here?" Since it was Kangxi who called someone, he had to go. Therefore, Ma De had no choice but to follow Luo Xin and a group of subordinates behind Su Lun towards Deqing Tower.

"The uncle and the sixth master went to the queen mother to say goodbye, and when they saw the master, they chatted and chatted to arouse the master's interest, so they came out together to breathe...... Just now, before the master entered the house, he also chatted with the master for a while. "Although Su Lun is already the first guard of Ouchi, he can't compare with Wu Dan. Wu Dan's status is enough to be on an equal footing with the minister of the study, and he can not sell anyone's face, but he can't, he can't be rude to a courtier like Ma De, who is quite valued by Kangxi, not to mention that Ma De is next to Luo Xin, who is very favored in front of the Empress Dowager, so he doesn't dare to be rude.

"Lord Gao was there just now?" It seems that Kangxi came to inspect it temporarily today, does this guy really want to play some kind of "Weifu Private Interview", Ma De pouted secretly.

"Master Gao is the chief examiner, and he wants to enter the invigilator, just passing by, the master chatted with him for a while......" Su Lun explained.

"Oh!" Mader nodded and didn't speak again.

……

Deqing Building is a famous store in the city of Beijing, not too far from the Gongyuan, not far away.

Su Lun took Ma De and Luo Xin straight up to the third floor, where Kangxi and his two brothers had already taken over the entire floor. However, although it is said to be breathable, the Ouchi guards around the three of them are still a large group of people who are openly and secretly, and the second floor is actually almost all covered. In the entire Deqing Building, except for a few guests on the first floor, the others are either the inner guards or the palace guards, which are really "shrimp groups" (in the Qing Dynasty, the guards are also called "shrimp"), so Ma De and Luo Xin's subordinates can only be with these guards, and only the two of them can go up to the third floor.

"Ma De, what about Fei Aiqing? I remember that you were always together, why weren't you together today? After meeting and saluting, Kangxi let Ma De and Luo Xin sit opposite him, with Fuquan and Changning on both sides. However, this special encounter made Ma De secretly thank Bumin. An emperor and two princes stayed opposite each other and stared, and no one felt comfortable.

"Back to the emperor, Brother Yu was invited by Yin Yuheng of Shuntian Mansion, saying that he wanted to rectify the overpass, and wanted to ask his opinion, so Sister Jing went with him; As for Fei Lao, his old man is trying to find a way to improve the production efficiency of Fengtian at his residence! ”

"Productivity? Mader, what does that mean? "Prince Gong Changning and Ma De and others are also acquaintances, so they don't speak politely, and they call their names and surnames as soon as they come up.

"This, how to say it......" was quick to talk for a while, and moved out a "new word", but Ma De couldn't think of how to explain it for a while.

"Production efficiency, to put it bluntly, is to allow a person to do more work in a certain period of time......" Luo Xin saw that Ma De was suffocated, so he made a more popular explanation on the side. This is not talking about any state affairs, and it is okay for her to interject.

"Hehe, that's interesting, Ferdinand has such ability? There is a number of dry meals that each person eats, how much work they can do, and more work? Could it be that he, Ferdinand, could have turned a powerless guy into a strong man? Chang Ning said with a smile. And beside him, Kangxi and Fuquan were also smiling, and their faces were extremely obvious in disbelief.

"Lord Gong, you are mistaken. You don't have to have more strength to do more work, and the knowledge in this is great......" Ma De saw that Chang Ning didn't believe it, and immediately argued.

"Oh? This work is still learning? What the hell is going on? Ma De, you can talk about it, this king wants to listen to what kind of knowledge is here......" Fuquan glanced at Kangxi and spoke on the side.

"Prince Yu, do you know what 'integrated mathematics' is?" Luo Xin said suddenly.

"What? Command...... What is the system? Fuquan was stunned, stunned that he couldn't get the four words "overall mathematics" together.

"Lord Wang, Luo Xin, what she said is 'co-ordinated mathematics'!" Ma De said with a smile, looking at Luo Xin's eyes full of admiration. It's worthy of being his wife, this brain is good, isn't coordinating mathematics a kind of knowledge to arrange work?

"I understand what mathematics means, but what does it mean to 'coordinate mathematics'?" Kangxi asked. Although he has learned a lot of things in Western studies from Western missionaries, such as plane geometry, astronomy, calendars, etc., and knows that mathematics and arithmetic are fundamentally different, Kangxi really doesn't know what it means to coordinate mathematics.

"Back to the emperor, the overall planning of mathematics, in fact, is also the overall method, which is a mathematical method for arranging the work process." Ma De remembered the texts he learned in middle school quite clearly, so he answered smoothly.

"Scheduling the process?"

"Not bad. Your Majesty, the overall planning method is actually the arrangement of the process. For example, if you want to make a pot of tea. The situation is: boiling water is not available; The kettle should be washed, and the teapot and cup should be washed; The fire is lit, and the tea leaves are there. So what to do? There are three methods: A, B, and C. Method A: Wash the kettle, fill it with cold water, and put it on the fire; While waiting for the water to boil, wash the teapot, wash the teacups, and take the tea leaves; Wait for the water to boil and make tea to drink. Method B: Make some preparations first, wash the kettle, wash the teapot and cups, and take the tea leaves; Everything is ready, pour water and boil water; Sit back and wait for the water to boil and make tea. Method C: Wash the kettle, fill it with cold water, put it on the fire, and wait for the water to boil; After the water boiled, I hurriedly looked for tea leaves, washed teapots and cups, and made tea to drink. …… May I ask your majesty, which of these three methods does you think is the most time-saving? "It's good to be able to endorse it," Madele asked leisurely.

"Hehe, of course the first method saves time and calmness." Kangxi smiled.

"The emperor's discernment, this is actually the wonderful use of the overall planning method." Mader said.

"What else should I be awesome about, what is this? Can this also be considered a college question? Ma De, you shouldn't have casually used words to get the emperor and this king, right? Prince Gong Chang Ning said dissatisfied. He really didn't find anything noteworthy in this.

"Lord Wang, how can you talk nonsense? The benevolent see the benevolent, the wise see the wise, why did you talk about bullying the king again? Luo Xin said to Chang Ning.

"Yes, this king can't afford to offend you Xingege, it's done, I won't say it." When he was in Fengtian, Chang Ning had learned Luo Xin's chili temper, and even heard that she was tough in front of thousands of elite cavalry, teaching her main general Nian Qianyao a lesson. Now, Luo Xin has the support of the Empress Dowager Xiaozhuang behind him, and he can only soften his mouth.

"I remember that in the history books, during the Northern Song Dynasty, the Fenghua Hall caught fire, and most of the palace was burned down. At that time, Bi Shichi, the waiter of the Ministry of Works, was ordered to repair. He did not wait for all kinds of materials to gather before starting, but directly dug up the royal street, burned bricks with soil, and used the burned bricks to build Fenghua Palace. After that, the dug royal street was connected to the river in the palace, and boats were brought in to transport timber and various materials to the construction site

When the Fenghua Hall was completed, he opened a diversion canal to drain the water in the royal street, and buried the bricks and mud that were transported later and the sundries left after the repair of the temple into the ground, and then filled the royal street. In this way, in less than a month, all the work has been done, much faster than people think. At that time, everyone called Bi Shichi a capable official...... Now that I think about it, this Bi Shichi's approach is also quite in line with the meaning of this overall planning law. Kangxi said. (I remember that there was such an incident in the Song Dynasty, but unfortunately I can't remember it clearly, so the palace name and the character name are all fake, so don't take it seriously.) ）

"Listening to what the emperor said, it seems quite like this. It seems that it is worth thinking about ...... good students" After listening to Kangxi's words, Fuquan also had an understanding.

"Ma De, I have studied Western studies with Tang Ruowang and Nan Huairen, why haven't I heard of the co-ordination method in Western studies?" Kangxi asked Ma De again.

"Your Majesty, the overall planning method is a practical knowledge. However, in Western studies, it is just a sign of it, and not many people know about it. Minions and others have only learned a little occasionally, and they are far from attainments. "Old man Hua Luogeng, it's not that we don't want to mention your name, the key is that we can't mention it now, although I learned this co-ordination method from you, buddy, but...... Alas, I'm sorry. Ma De said to himself.

"Fengtian's turn of things is not as easy to do as boiling water to make tea or repairing the palace, it seems that Ferdinand is busy this time. I said Made, since you are a group, why don't you help take a look? Chang Ning asked again.

"Lord Wang! Every man has his own thing. Although the slave is close to Fei Lao and Brother Yu, they are like a family, and they often discuss everything. However, Fei Lao is the Yin of Fengtian Mansion, and the matter of Fengtian is still the most clear to his old man, we don't understand the situation, and we are messing around with ideas, I am afraid that it will become more and more messy, which will make Fei Lao annoyed. Mader replied.

"Hmm!" Chang Ning, Kangxi, and Fuquan glanced at each other, and they were all very satisfied with Ma De's answer. Kangxi nodded secretly in his heart: "This Ma De is telling the truth, and he doesn't shy away from the suspicion of forming a party at all...... He seems to be an open-minded man. ”

"Your Majesty, the slave has a word I want to ask, I don't know if it's okay?" Ma De suddenly asked Kangxi again.

"What?" Now that it has been preliminarily determined that Ma De is open-minded, Kangxi's face is even more pleasant.

"Your Majesty, it's the things that Fei Lao said a few days ago...... "Although Fuquan and Chang Ning are princes and have also commanded the army, they have no power to discuss politics, so Ma De didn't say what happened that day, anyway, Kangxi understands it.

"That's what happened." Kangxi smiled slightly, shook his head again, and said, "No, the law of the ancestors cannot be changed without authorization." Although Fei Aiqing has good intentions, there is a lot of trouble in this, even if I am I, I can't make a decision casually. ”

"That's right...... In that case, the minions and others have nothing to say. However, please remember that Fei Lao has worked hard and forgiven his sins......" Ma De stood up and knelt down and kowtowed to Kangxi. Luo Xin naturally knew what he meant, this was taking advantage of Kangxi's good mood, pleading for Fei Lao's head insurance and striving for the best result, so she also knelt down towards Kangxi. However, seeing them kneeling on the ground, Fuquan and Yongning beside them with unknown faces, Kangxi didn't say anything, but just said to himself: "The ancestors didn't allow the banner people to do business, but the Internal Affairs Office didn't have too many restrictions. Now that I have officially appointed Ferdinand as the Minister of the Interior, I think he should know what to do if there is something going on in the future......

"The head of the Ministry of Internal Affairs? …… The slave thanked the emperor for Fei Lao. Ma De and Luo Xin quickly understood the meaning of Kangxi's words, and they were immediately overjoyed, and of course, they had to kowtow when they were happy.

"Haha, get up! I am not an unreasonable person, and I am a person who really thinks about my Qing Dynasty, how can I be guilty? You're worrying too much. Kangxi smiled and put on a holy look, and ordered someone to pick up Ma De and the two.

"Your Majesty, what the hell is going on? What is the one who does not condemn one? Confused by the words between Kangxi and Ma De, Chang Ning couldn't help but ask again.

"Hehe, lord, is it like this......" Hearing Chang Ning's question, and seeing that Kangxi had no objection, Ma De told him about the situation that day, of course, while talking about him, he mixed a few words of praise for Kangxi in the middle.

"What else should I do? The emperor even pardoned Guo Xiu's fierce seed at the beginning, can Ferdinand still be compared to that Guo Erpole? You guys, you're worried, you're worried......" After listening to Ma De's narration, Chang Ning said again and again.

"Hehe, what the prince said is ......" Ma De laughed again and again, but his heart suddenly felt crooked.

A few people continued to chat, Kangxi didn't speak, and Ma De couldn't retire and leave, so he could only stay there with Luo Xin. However, after chatting for a while, there was a commotion not far away.

"Sulun, go see what's going on." Hearing that the commotion was particularly loud this time, and the direction was a little wrong, Kangxi ordered Sulun.

Su Lun took the order and left, and soon he returned, but his face was not very good.

"Your Majesty, it seems that something happened to the Gongyuan!"
