Chen Wenhui said: "Of course, I solved it myself. I'll do anything more difficult than that. For example, in the arithmetic of earth and stone engineering, if you know the length, width and height, you can calculate the volume, the cylindrical shape can be calculated, the conical shape can also be calculated, and the trapezoidal shape can also be calculated. ”

Chen Wenjun knows this, Chen Wenjun has heard his second brother say countless times that his sister is too good at arithmetic, these things that he has to count for a few days and need many craftsmen to help, she can calculate it at once, almost in the blink of an eye, which really amazes him. Later, it is said that the second brother also learned this aspect of arithmetic like his sister, and his sister gave him a few formulas, and he taught it in three nights, and later, the second brother himself was able to calculate so fast.

But these words fell into the ears of those people in the Hei family, and there are many people in the Hei family who are interested in these, such as the three in Jin Mingpu, who are already obsessed with the way of arithmetic, and they are even more scratching their ears and cheeks when they hear it, and they can't wait to study and discuss it now.

In addition to them, the three of Heigetang are also very concerned, and they can't wait to ask immediately, they have to build a large number of projects every year, there are many arithmetic problems, and they carry out forging and manufacturing machinery, all of which need to be accurately calculated, which also requires a lot of arithmetic knowledge, it can be said that the three of Heigetang, in arithmetic attainments are no less than Jin Mingpu, but they are more inclined to plane geometry and solid geometry, and Jin Mingpu is biased towards mathematics.

Also interested in this are the three members of the Calligraphy and Painting Hall. The calligraphy and painting hall also shoulders the responsibility of cultivating the children of the black family, that is, running a school to educate the children of the black family. Arithmetic is an important course. Therefore, the successive hall masters and deputy hall masters of the calligraphy and painting hall have some small achievements in arithmetic, such as the city lord Ding Chuan, who was the hall master of the calligraphy and painting hall before becoming the city lord, and had studied arithmetic for a period of time. So, yesterday, those topics of Chen Wenhui. He was also happy to see the hunt, and couldn't help but count it himself.

The three beauties of Meixiutang didn't react much to this. There are also places where Meixiutang uses arithmetic, such as arithmetic fabrics and the like. But there are too few to be counted, but they can be the hall masters, and the deputy hall masters have all studied in the black family system, and they have also learned arithmetic, so they can also be regarded as some simple things, but there is no Jin Mingpu and Hei Getang fanaticism for these.

The most stable is the Black Knife Hall. These three are all authentic martial artists, although they also learned some arithmetic knowledge when they were children, but after focusing on martial arts, they didn't think about these problems anymore.

The three members of the Alchemy Hall looked dispensable. None of them liked arithmetic very much, and more important to them was the medical aspect. Therefore they are also sitting in the presence of the old gods.

Tang Guanghui and Chen Wenhui of Jin Mingpu were already familiar with each other, so they didn't have any worries and said directly: "Miss Chen, I don't know if you can help me solve a few problems?" ”

It looks like I'm going to start researching it right away.

Chen Wenhui smiled silently. Chen Wenjun coughed and said, "Master Tang, if you want to study arithmetic with your sister." You can come to our Shin Kong City, we are always welcome. I wanted to talk to the lord of the city about cooperation yesterday, but as a result, I was always calculating the topic yesterday, and I didn't have time, so today we want to solve it as much as possible. Our Xinguang City is still in the initial stage, and it is not a short time for our brothers and sisters to come out. There must be a lot of business piled up in the city waiting for us to go back and take care of it, so we don't have time to stay here for long. ”

With these words, the city lords Ding Chuan and Tang Guanghui both blushed a little, and people came all the way over. It's just to cooperate with them, but as a result, these people only care about pestering other little girls to do arithmetic, is this what is going on?

Ding Chuan hurriedly said, "Hey, I'm sorry. As soon as those of us encounter the matter of studying knowledge, we can't control it, and we forget all the serious things. Please tell me about our future cooperation. It just so happens that this year, the hall masters and deputy hall masters of our black family are here, so let's discuss it together. ”

Chen Wenjun said: "Before, we just wanted to set up our family's shops and restaurants in the Black Iron City, and we also regularly bought some Black Iron City specialties, and we also had some Central Plains specialties to trade with you." Now I don't think so. I want to ask one thing now, where can the current fleet of the Black Iron City go? Is there the most trade in Nanyang, are there any supply points, and can you share these supply points with us? ”

Ding Chuan's face changed when he heard this, and he couldn't help but look at Huo Hongming, the hall master of the Black Knife Hall. Huo Hongming's face did not move at all, but his eyes burst out with a shooting light. Ding Chuan's heart calmed down and said, "Where is City Lord Chen talking about?" Our Black Iron City is just an inland city on Yizhou Island, where there are sea ships, where can we reach the South Seas, and there is no supply point. Since our ancestors arrived on Yizhou Island, we have been cut off from the mainland for hundreds of years, and all these years we have been working behind closed doors. ”

Chen Wenjun had expected it, and he was not busy talking, but looked at his sister.

Chen Wenhui said: "I have long heard that the children of the Hei family in Black Iron City are all talented, it just so happens that there are some talented people under my subordinates, I want our people to have a small competition with the people of your black family, okay?" ”

Huo Hongming, the hall master of the Black Knife Hall, had not been silent, but at this time, he raised his eyebrows and asked, "I don't know what Miss Chen wants to try?" ”

Chen Wenhui said: "The black family is full of talents, all-encompassing, and the people under my command are not talented, but I want to try each one." ”

As soon as he said this, all the hall masters of the Hei family were moved. These people are not stupid, on the contrary, they are all extremely smart people, and when they hear it, they understand that this is a competition proposed by the Chen family brothers and sisters in order to share the interests of the sea with them.

It's just that the black family thinks highly of themselves, and they never thought that someone would provoke them like this, and it was such a comprehensive provocation, which was really the first time in hundreds of years.

Suddenly, several hall masters were in high spirits and said to the city lord one after another, asking for a competition.

City Lord Ding Chuan was also a little annoyed, thinking to himself, we respect your Chen Wenhui's arithmetic knowledge, it's not that we are afraid of you, this is respect for knowledge, you two young people, you are actually going to provoke the Hei family, even the three major families on the island are also desperately trying to tie up the Hei family, where can anyone dare to provoke?

Thinking of this, the city lord Ding Chuan said with a dark face: "The way of learning is to make progress in continuous learning, so our Hei family has to compete every year." Now, Miss Chen proposed to have a competition, so let's confirm each other and learn from each other. Which one comes first? ”

Before the words fell, Tang Guangqi had already stood up, and first arched his hand to the hall master Huo Hongming and said, "Hall master, the last general is not talented, and I want to fight the first battle." ”

Before Huo Hongming could speak, Chen Wenhui said: "I also agree with the city lord's statement, the important thing is to keep exploring, the road is long, and I will go up and down to seek." Only by constantly learning can we continue to make progress, so I proposed to have a competition, but we came from afar, and there were not many people with us, so we could only compete once in each class, what do you think? ”

If Chen Wenjun said this, they would naturally have a lot to refute, but it was the delicate Chen Wenhui who said it, Chen Wenhui is an eleven-year-old girl, much younger than all of them, and many of them have granddaughters who are so old. Naturally, it's not good to deal with her, and besides, she has already shown that this competition is for the study of knowledge, and there is no mention of what will happen if you win or lose, which is equivalent to playing a friendly match, what can you do with others? Besides, the tradition of the Black family is to respect knowledge and talented people, so the successive city lords of Black Iron City are rarely the masters of the Black Knife Hall who hold the power of the army, and most of them are from the Calligraphy and Painting Hall and the Jin Ming Shop.

Ding Chuan looked at his hall masters, and saw that they were all nodding slowly, so he smiled and said, "It's a guest from afar, we should respect it, let's try it every time, and the question will be made by Xinguang City." Just think of it as an exchange. ”

Huo Hongming said: "Let's come to the Black Knife Hall first." Let's just let Deputy Hall Master Tang and Xinguang City have a discussion, and it's over. ”

Tang Guangqi's face was overjoyed, and he happily accepted the order, standing and waiting for Xinguang City's side to fight.

Chen Wenhui was already prepared, looked at his brother, and said, "Just let my guard Jian Da and Deputy Hall Master Tang have a discussion." ”

Jian Da, who was sitting at the bottom of the house, immediately stood up when he heard this, walked to the front and asked, "This place is narrow, where can we compete?" ”

Tang Guangqi took a closer look at Jian Da, and saw that Jian Da was in his twenties, similar to his age, heroic, like an unsheathed sword, and he cherished it in his heart. He smiled and said, "Not only is the place narrow, but there are also ladies present, we are not good at fighting and killing, so let's go to the open space on the other side of the lake and try it?" Is it a test of fists and feet, or a sword? ”

Because the city lord said just now that the topic was from Xinguang City's side, Tang Guangqi asked Jian Da to ask the question. Jian Da said: "I am a person who uses a sword, how about I try my swordsmanship?" ”

Tang Guangqi was overjoyed: "Okay, I've always been obsessed with kendo, so I just took this opportunity to learn from the masters of the Central Plains." ”

After saying that, he turned back to the seat and took out a sword. This sword has a scarlet spike, a beautiful and smooth pattern engraved on the white scabbard, and Tang Guangqi is dressed in a cyan suit, which looks like the style of those swordsmen that Wen Hui saw on TV in his previous life, Wen Hui couldn't help but cheer loudly in her heart, and at the same time thought to herself, Fortunately, I made Jian Da prepared.

I saw Jian Da reach out and take off his coat, revealing a neat white power suit, turned around and grabbed a sword, choked and came out of the sheath, like a pool of autumn water, the people in the Black Knife Hall and the Black Getang couldn't help but shout: "Good sword." ”

Chen Wenhui was full of pride.
