Chen Wenhui was not angry enough, and then said: "For example, the most girls in the Black Academy are Meixiutang. But the deputy hall master of Meixiutang is here, I want to ask, can you Meixiutang embroider my veil like this? ”

After speaking, he finally took out the half-hidden and half-exposed handkerchief in his hand, hanging Zhou Mingli's appetite, and spread it on the table generously, the kitten on the handkerchief looked cute, the eyes were particularly expressive, and he had a naughty demeanor, even Ding Chuan and others, who didn't know how to embroidery, felt that they were skilled, and couldn't help but secretly draw a pair of hands in their sleeves, and Zhou Mingli, as an insider, had straight eyes, and finally couldn't help but stretch out his hand and take the handkerchief in his hand. It was a docile expression, and Ding Chuan was amazed, no wonder Zhou Mingli lost her temper for this handkerchief, it is indeed a miraculous skill, in this way, there is really nothing in this beautiful embroidery hall that can teach other little girls. But Ding Chuan was unwilling to say: "Well, actually, I see that Miss Chen has a talent for inventing utensils, so I want to introduce you to Heigetang." ”

Qin Mingming, the deputy hall master of the Black Ge Hall, nodded and looked at Chen Wenhui gently. Before, Chen Wenhui's recliner for washing her hair was very liked by Qin Mingming, and she was very appreciative of Chen Wenhui's ingenuity, but now when she looks at people, she is a beautiful little girl, full of intelligence, such talents must be recruited to her own Heigetang. How do you know, Chen Wenhui smiled lightly and said: "I think there is nothing I want to learn in Heigetang, for example, this, can Deputy Hall Master Qin understand it?" ”

As he spoke, he plucked a very beautiful rose-shaped gold ring from his head. This golden ring is a flower branch entwined with a half-opened rose, which is beautiful but not surprising.

Qin Zhizhi had already seen the gold ring on Wen Hui's head, but he thought it was very well designed, but he didn't look carefully, after all, he was a little girl, how could he, a man in his thirties, be embarrassed to stare at other people's hair.

Now that Chen Wenhui handed over the golden ring, Qin Mingzhi knew that this golden ring would not be so simple, and hesitated, after all, the other party was a little girl. If it's an indigenous woman, it's fine, but the other party is a girl from a big family, how can she take the gold ring that has just been plucked from someone's head? But seeing Wen Hui's firm expression, he secretly felt ashamed in his heart. The little girl is just testing his skill level, how can he think of etiquette again. So, I didn't hesitate, I reached out and took it, and as soon as I took it, I was stunned, this gold ring is really a hidden mystery, and I actually looked away before. He fiddled with it carefully for a while, pressed a bracket, and the half-placed rose suddenly stretched out its branches and leaves. The flowers are all released.

This change surprised Qin Mingming, and also surprised Zhou Mingli, where is there a woman who doesn't like jewelry hairpin rings, Zhou Mingli's brother is Zhou Maocai, the hall master of Heigetang. In the past, Zhou Maocai would give a copy of any kitkat jewelry made by Heigetang to his two sisters, so Zhou Mingli had a lot of kitkat jewelry, but he had never seen such a thing, and he couldn't help but show a look of envy.

Tang Guanghui, the owner of Jinming Shop, who had been silent all the time, had bright eyes, such jewelry was really a coincidence. If you take it out and sell it, it will be very popular. It seems that not only the Hei family has good things, but there are also good things in Xinguang City, which he didn't fancy before, maybe he should really cooperate with them, not to mention anything else, if they cooperate to do business, they can communicate with each other. You'll definitely be able to make more money.

Ding Chuan was also taken aback, this girl from the Chen family was really prepared. At this moment, it was no surprise that Qin Mingming also fell into a scientific frenzy, fiddling with the golden ring repeatedly. Serious study, he couldn't say a word, in fact, it wasn't that he didn't want to speak, he entered the state of research all of a sudden, and he didn't think that this was not his studio, it was the hall of the City Lord's Mansion.

Ding Chuan looked at the two obsessed Mei Xiu Hall deputy hall masters Zhou Mingli and Hei Ge Hall deputy hall master Qin Mingming beside him and shook his head. This little girl is really hard to deal with.

How do you know that Chen Wenhui is still not satisfied, and she wants to provoke Jin Mingpu, I only heard her say to Tang Guanghui, the owner of Jin Mingpu: "Tang shopkeeper, I want to try it with you." ”

Tang Guanghui was very surprised and said, "What are you trying to do with me?" ”

Chen Wenhui said: "We try arithmetic. About buying and selling. If a businessman is not good at accounting, how can he do business? ”

Ding Chuan didn't say anything, this little girl surprised her too much. This Chen family, this Xinguang City also surprised him too much, it turns out that people have so many good things, it seems that he was too arrogant last time, the master is right, the biggest enemy of people is pride.

Tang Guanghui is a businessman, different from those Frankensteins, there is a kind aura on his body, I saw him smile slightly and said: "Miss Chen is naturally smart, but after all, she is too young, I can't win, let's do this, I'll call a disciple to compete with you tomorrow." ”

This is already a lot of face for Chen Wenhui, as a shop owner of Jin Mingpu, in addition to being able to do business, he is also a mathematician. Very studied for arithmetic. In fact, he had been studying the scriptures before, and he had solved a lot of problems. As a mathematician, how can you compete with an eleven-year-old girl without shame? Isn't that bullying? It's better to send your own disciples to teach the arrogant Chen Wenhui a lesson, and teach her to be humble in her studies.

Chen Wenhui didn't appreciate it, you are proud, I will defeat you fiercely, and I will be more proud than you, she smiled slightly and said: "There is no need to test too difficult, I will say a question, if the Tang shop owner can answer it, I will go to the black house to worship the Tang shop master as a teacher to learn the way of arithmetic management." ”

Tang Guanghui still refused, Chen Wenhui had already said: "My topic is about planting, in a side-by-side ten-ridge field, choose two ridges to plant two crops A and B, each planting one ridge, in order to facilitate the growth of crops, the interval between the two crops A and B is required to be no less than 6 ridges, how many different selection methods are there?" ”

This is a permutation and combination problem, and in his previous life, Chen Wenhui only learned it after he went to college, and I believe that no one in the current black family can solve it.

Sure enough, Tang Guanghui began to be careless, and calculated it with his hand in his sleeve, and as a result, he found that such a seemingly simple problem was really complicated to solve, and it was no longer possible to calculate silently in his heart. Tang Guanghui immediately asked for pen and paper like Ding Chuan, and Ding Chuan also knew mathematics. also calculated silently in his heart, and also found that he couldn't calculate it silently, and after listening to Tang Guanghui's words, he hurriedly called his subordinates to prepare paper and pencils. And said that he would prepare two copies, he was already attracted and wanted to do the math himself.

The servant was about to leave, and Qin Mingzhi on the side also spoke up: "You also have to get me a pen and paper." ”

Zhou Mingli had been looking at Chen Wenhui's handkerchief seriously, and couldn't help but raise her head when she heard the words, in fact, she also knew a little about these arithmetic and the like, the children of the Hei family were all knowledgeable and talented, she didn't expect that it sounded so earthy, such a simple topic, and it could actually make three of the best people of the Hei family put forward it at the same time to take paper and pen to calculate. So she also quietly counted it in her heart.

The servant quickly brought three pens and paper. As soon as the three of them got their hands, they couldn't wait to count it. Chen Wenhui had a smile on the corner of her mouth, quietly gave her brother a look, drank tea leisurely, and tasted a small snack with tea in a leisurely manner.

The brother and sister chatted softly. It's really a stealing half a day. Time passed quickly, originally, I had finished lunch when I came, but in the blink of an eye, an afternoon passed, and the light in the hall gradually dimmed, showing that the sun had set outside.

The people in the City Lord's Mansion don't know why, why are the two brothers and sisters from Xinguang City so valued. This meeting was an afternoon, and it was time for dinner, but before he left the council hall, those stewards were talking about it, which is really rare. Usually, there were many powerful people who came to visit the City Lord's Mansion. However, even if the head of the Huang family, the Gu family, the Liang family, or the head of the indigenous people of the big tribe arrived, the city lord did not receive him for such a long time. This time it's unprecedented.

The news quickly reached the backyard. The city lord's wife is a member of the Gu family, Ding Gu has been the city lord's wife for a few years, and she knows her husband's temperament very well, and she also begins to wonder why this brother and sister of Xinguang City are so valued by her husband. Before, she had received a letter from her mother's family, asking her to take care of the Chen family brothers and sisters, after all, although they were young, they held real power, Xinguang City now brought a lot of silver to the Gu family, and they were the gold owners, so they must take care of them as much as possible.

However, Ding Gu knew that his husband would not take care of the city lord brothers and sisters of Xinguang City in the face of his mother's family, so he was a little embarrassed, but he didn't expect that without her greeting her husband, the husband actually looked at the two brothers and sisters so differently, which was really unexpected, so Ding Gu was even more curious about the two brothers and sisters, and made up his mind that he would definitely invite them to sit in the mansion tomorrow.

The reactions of the people in the City Lord's Mansion here are mixed, in the hall, this problem has been solved, of course, the first one to be solved is Tang Guanghui. After all, although these people can do arithmetic, only Tang Guanghui can be called a professional.

Tang Guanghui said to Chen Wenhui: "This problem is really difficult, and its practical stupid method can be arranged, but then it is not arithmetic, I calculated a lot, so I found a way, and the final number is twelve, right?" ”

These words woke up the city lords Ding Chuan and Zhou Mingli, who were still struggling next to them, and Qin Mingming. The three of them didn't have a clue yet, and at this moment, Tang Guanghui had already calculated it, and they all looked at Wen Hui with blank eyes, waiting for her to announce the answer.

Chen Wenhui smiled slightly and said: "The Tang shop owner is really everyone, this answer is right, but I don't know how you calculated it?" ”

Tang Guanghui was busy telling the process of his calculations, and I have to say that he still used a stupid method and did not use a permutation and combination formula.

However, this method is much more ingenious than Ding Chuan and Zhou Mingli, and Qin Mingzhi's own method is already much more ingenious. The three of them all looked at Tang Guanghui with appreciation, and thought to themselves, it is really a wonderful idea to be worthy of being the most outstanding arithmetic master of our black family.

How do you know that after listening to Tang Guanghui's words, Chen Wenhui shook her head and slowly said her own method, this is the knowledge obtained in the previous life, using the formula of permutation and combination, which is naturally much more ingenious.

Tang Guanghui, Ding Chuan, Zhou Mingli, and Qin Mingzhi were speechless when they heard Chen Wenhui's method.
