Murda rode the well turtle out of the book. I thought that the word was known, but I don't know what customs Lu Dao has in Daqin, and I don't know what etiquette Lu Dao says. Although he is a descendant of China, he really doesn't know the etiquette of his ancestors at all. For example, when I really saw Qin Shi Huang one day, I didn't know how to kneel three times and knock nine times. Thinking about it, Moda rode the well turtle to the "Li" character of the Great Highness.

Before entering the main hall, Mao Qiuci and Du Ji chased out from the word soil.

"Moda, it's not so easy for you to humiliate our Du Daoxiu and want to leave! I won't agree to Mao Qiuci! ”

Moda was very annoyed in her heart, why didn't these two people give up. If you win, they can't do it, you can't hide by yourself, and now they are chasing them out endlessly. Raise your eyes to look at the two of them, said

"Brother Mao, you call it all extermination, why bother. Just now, Du Daoxiu was just careless and let me play a game. I know in my heart that the great talent of the Dao Cultivator is not enough. Otherwise, I'll go back to the book and compensate you in front of you. ”

"Isn't it a loss?! How could Du Daoxiu's reputation be ruined by you, just now Daoxiu was unwilling to use all his strength, and I was afraid that he would bully you, a newcomer. Now I will accompany you with Du Daoxiu to enter the method of counting and arithmetic among fellow practitioners, do you dare?! ”

"Well, initiates don't dare. Presumably Brother Mao must be a master of arithmetic when he says this, you two please first, and I will arrive later. ”

"Well, I don't think your lame leg can catch up with us! Brother Du, let's go. ”

After speaking, the two of them stepped into the 'counting' hall.

Moda laughed in his heart: Arithmetic, I just used the math knowledge of modern elementary school to get you done. Well, since you are dead, I will show no mercy. shouted 'hot sauce', and drove the well turtle to 'count' the soil.

As soon as he entered the main hall, Moda was startled, and there was a huge military formation with bronze men in the main hall. Each bronze figure was a thumb high and had archers, cavalry, infantry, charioteers. The phalanxes are neatly arranged. I thought: It's bad, don't you have to rely on my formation, how can I. It looks like it's going to be planted this time.

There were more than fifty Lone Bamboo disciples standing around the military array, and they thought they should be classmates. Mao Qiuci said loudly

"Ancestral Guide! Today, I am counting with Meda and the others, can I ask Senior Brother Zu to be a witness. ”

Mao Qiuci looked up at an old man and said.

"Who, didn't you see me count this army formation? Wait a minute, I'll get down as soon as I'm done. ”

Murda saw that the man had a white beard and was dressed in white clothes, like an old fairy. After waiting for a moment, the man floated down with a red-crowned crane.

"You disciples who are cultivating the soil, you are going to come and go every day. The reason why I am called a fellow practitioner is that it means to cultivate together, how can I fight with the same door. ”

"Ancestral Guide, you are merciful, how can this Moda be so wild that he actually took the initiative to challenge Du Ji's Guide. Now it's time to challenge you to be old. You are too deep to come forward, I just need to come forward. ”

Mao Qiuci actually hit a rake. Moda didn't defend himself, and looked at where Mao Qiuci was performing.

"Ancestral Daoxiu, what were my grades when I graduated from the 'Counting' Soil?"

Mao Qiuci asked

"It's a master, you can be regarded as a master, you can be regarded as basically mastering the "Yellow Emperor Ninety-Nine Sutras"."

Zu Dao Xiu replied

"Okay, I'll compare this algorithm with you today!"

Mao Qiuci's eyes revealed a fierce light, and he was extremely proud. Murda said

"Well, what's the algorithm?"

"Look at this army first, how many archers are there? I can figure it out in no time."

Murda looked back and saw that the archer formation was a phalanx, with nine columns and nine rows.

"81 people!"

Some disciples immediately counted them one by one, and after a while they turned around and shouted

"Accurate!"

"You instruct a team of people to test me!" Mao Qiuci looked proud.

"How many of those shieldmen there are?" Moda pointed to a military formation of seven rows and five columns.

"35 people!" The disciple counted for a while and shouted

"Accurate!"

"Well, that's right!"

Mao Qiu's words are proud.

Mo Da thought to himself, could it be that this "Yellow Emperor Ninety-Nine Sutra" is the multiplication formula we memorized in kindergarten? It is no wonder that Mao Qiuci is proud, with the level of mathematical development in the Qin Dynasty, it is rare to be able to use multiplication formulas.

So he casually pointed to a phalanx of crossbowmen

"Where's this?"

Mao Qiuci was stunned, this phalanx has 11 columns and 27 rows. It is beyond the scope of the multiplication formula, and I am sweating anxiously. Babbling

"Ten is a hundred, and ten is a hundred, and a column of twenty-seven, and seven times ten is seventy. In common...... Two hundred, two hundred and twenty-seven, plus seventy....... two hundred and ninety-seven! Wait...... yes, two hundred and ninety-seven people......"

After Mao Qiuci finished speaking, he looked at the disciples who counted the points. After a long while, the disciple replied

"Two hundred and ninety-seven! Accurate! ”

Mao Qiu's words were very proud, and everyone around him applauded. Murda thought that this was indeed a quick calculation. Mao Qiuci said proudly

"Look at this array! How many people! ”

Murda counted it, and there were 11 columns and 72 rows. Blurt out

"Seven hundred and ninety-two!"

Everyone was stunned, it was hard to imagine that this cripple was so fast. Some disciples immediately counted, and shouted after more than ten minutes

"Accurate!"

The audience was in an uproar. Mao Qiuci's face turned pale, and he pointed to a cavalry formation

"How many people are there?!"

Murda looked like a wedge-shaped formation, with one person in the first row, and one more person in each row in the back than in the front row, for a total of fifty rows. Moda picked up a branch and wrote the formula on the ground: (1+50)x50/2 and 51x25 multiplication on the ground, and replied

"One thousand two hundred and seventy-five!"

Everyone was shocked, so fast. It takes half an hour for others to calculate, but Moda can calculate it in less than a minute.

"Wizard! I've been teaching arithmetic here for 50 years, and you're the first disciple in 50 years to be so fast without practicing the Yellow Emperor's Sutra! It seems that your talent for algorithms is different from ordinary people! Tell me how you did that. ”

The ancestral guide was amazed.

"Disciple Xian Chou, in fact, these are the arithmetic and vertical formulas that children in my hometown will learn, if you are willing to appreciate your face, I will immediately present this difference series and vertical algorithm."

Ancestral Daoxiu took Moda's hand and sat on the well turtle. The two discussed the calculation just now, completely ignoring the stunned crowd next to them, and even put Mao Qiuci and Du Ji aside.

From the equal difference number series to the equal ratio number series, and from the triangle formula of hook three strands and four Xuanwu to the circle circumference formula, Mo Da talked about all the formulas he could think of, and Zu Daoxiu listened to it with relish, and sighed at the magic of these formulas while trying carefully.

Before I knew it, it was getting late, but the disciples who had listened to Moda for a few miles still didn't want to leave, surprised by the subtlety and accuracy of these algorithms. Mao Qiuci on the side really wanted to find a crack in the ground to get into, so he had to slip away. Although Du Ji sighed to himself, he was also admiring Moda for his talent and learning, and listened to his explanation carefully with everyone.

It was already the time to hold the lamp, and the ancestral guide asked everyone to go back first, and wait for the next day to ask Mo Da to teach these algorithms. Everyone was reluctant to leave, and Ancestor Daoxiu left Mo Da alone to continue to calculate these algorithms with him.

"Murda, these algorithms are really useful. I originally only said that the algorithm of "The Yellow Emperor's Arithmetic" is powerful, how do you know that your algorithm is more accurate and comprehensive. ”

"It's all the teacher's work, I'm just mastering it."

"These algorithms are good, but you want to learn the mental arithmetic of the secret art of solitary bamboo. After you have completed your studies, you only need to list these equations in your mind, and you can get the results immediately through the mental method. ”

"I can't ask for it! Please teach me! ”

"Haha I think what my ancestor Heng has learned all his life is a person with inheritance today! ”

Zu Daoxiu then took out the "Yellow Emperor Sutra" to teach to Mo Da, this Sutra has a total of 246 subsections according to the order of the solution method from shallow to deep, re-divided into multiplication and division, fraction, composite rate, interchange, two decay, superposition, surplus deficiency, equation, Pythagorean and other nine categories, the last section is the method of solitary bamboo mental arithmetic. With the help of pictorial memories and his extraordinary comprehension skills, Moda has mastered all the contents of these 246 chapters in less than half an hour. The ancestral director couldn't help but be amazed, and even Kuamoda was talented.

While the two were chatting, they suddenly heard Murda's stomach gurgling. Ancestor Daoxiu said with a smile

"You and I have come to practice, don't delay your body. Look at you, your stomach is empty. ”

Murda scratched her head and replied

"Don't hide it, I had a bowl of chicken noodle soup made by the Mo Dian brothers this morning, and let the two children swallow Mo Di and Mo Heng. At noon, Du Daoxiu had to compete with me, but he didn't have time to eat. In the afternoon, Mao Qiuci has to test the algorithm again, and in the evening, your Yellow Emperor's arithmetic is really exquisite, and I can't take care of eating. I'm really hungry now. ”

"You actually call Mo Dian's brother and sister?! Mo Dian, the elder brother of the 'Shennong Seed'. ”

"What is Transmission?"

"Teaching is a kind of master, responsible for all the teaching matters within the species."

Moda thought that Mo Dian was a stupid guy, but he didn't expect it to be a kind of strength, and he couldn't help but be in awe. I thought that this Lone Bamboo Clan was really powerful, just painting memories and the Yellow Emperor's arithmetic scriptures could already become a family. It also collects the world's writings, which is simply a museum of ancient Chinese science.

Just as he was thinking, someone outside shouted:

"Old man Zu, hurry up and release my brother! Otherwise, I'll rush in and embarrass you again! ”

Hearing this voice, Ancestor Daoxiu hurriedly dodged, shouting while dodging

"Ancestor, don't come! The question from last time has already made me think about it with gray hair! I'm going to kill me if you do it again! Murda, get out of the city quickly, this ancestor has to make me crazy if he breaks in! ”

Murda is puzzled, can anyone come up with a question to make it difficult for the guidance of several soils to be like this? Strange. Listening to the voice of this person outside, it is very familiar. Looking at the appearance of the ancestral guide, he must be really scared. It's not good to continue to bother yourself. So he said goodbye and drove the well turtle out of the main hall.

When I went out, I saw that the person who spoke was Mo Xin, and there was Mo Dian standing next to him, and Mo Dian was carrying Mo Di and Mo Heng. The four of them smiled and looked at Moda and waved their hands, and then looked at the well turtle under Murda, and the four of them smiled and leaned back together! As soon as he went out, he only heard a 'bang' behind him, and the ancestral guide Xiu hurriedly closed the door of the hall, which showed that he was extremely afraid of Moxin.

Murda was puzzled and said

"Mo Xin, how could this ancestral cultivator be so afraid of you?"

"This ancestor is an idiot in numbers, as long as it is about arithmetic, he will study it to the end, the master said that he has only been obsessed with this for decades, and never stepped out of the palace door for half a step. Although he is proficient in arithmetic, he will not be able to solve the puzzle as long as he is given some complicated information. ”

Mo Da thought, no wonder he can't put himself on the shelf every day, it turns out that he can't touch the ground anymore, and it's really pitiful to think about.

"What's wrong with you? Let these idiots actually hide from you like a plague god? ”

"I entered the sect with Mo Di Moheng, and the three of us practiced arithmetic at the same time. I'm very annoyed by the calculations of the formations, and I don't think there's anything new. Besides, why should the person who will lead the troops in the future personally order the troops, that is all done by the people below. What I want to think about is a way to break the formation, to win by surprise. Otherwise, how to win more with less? How to become a celebrity quickly? Remembered by the world? For the use of the Lord? I told the ancestral cultivator my thoughts, but I didn't expect him to say that I was a bastard and blasphemed the method of arithmetic. I made a bet with him that if a stick of incense could figure out my problem, I would listen honestly and let the three of us graduate if I couldn't. ”

"What's the subject?"

Murda was curious.

"Two dogs race, dog A runs fast, dog B runs very slowly, and when they reach the finish line, which dog sweats more?"

"Aren't dogs unable to sweat? How do you answer the tutorial? ”

He led two dogs and tried them in a few soils all morning, but the dogs just didn't sweat, and he didn't know how to answer. For several days in a row, I asked someone to buy different breeds of dogs at the bottom of the mountain every day, and I had to fight with myself every day, trying to figure out which one sweated more. His hair turned gray. ”

"You bad person, it's no wonder that the ancestral guide has lost to you."

Murda shook her head, feeling that Murshin was both smart and cunning.

"Although he has mastered the method of arithmetic in the world, he does not touch all things in the world. How do you know that the book of the Tao is dead, and all things are alive. The calculation can be certain, but there is no certainty in the outcome of the world. So I'm practicing in military strategy, and I always feel that those so-called art of war are like ancestral idiots. How can a soldier stick to the art of war? ”

Murda's listening to Moxin makes sense. Moxin continued

"Don't mention it, let's drink, my new research wine is called Zhuyeqing, please give it to you! Anyway, you're too slow. Fatty, you carry Moda and carry the well turtle! ”

Mo Xin pointed at Mo and said.

"Stinky letter, it's not enough for me to carry people, I have to bring another turtle!"

"Are you still drinking the wine?"

After that, he lifted the two clay bottles and looked at Mo Dian.

"Wine, wine....... this and this....... wine is good, wine is good......"

"Does the letter still stink? Stinky people make stinky wine, so don't drink it. ”

"It doesn't stink, it doesn't stink, people stink, and wine doesn't stink."

Mo Dian's eyes kept staring at the two clay vases.

"What?!"

"No, no, the wine is also fragrant. No, it's the smell of wine, and the people are even more fragrant! Let's go! ”

After that, he didn't wait for Moda to react, so he picked up Moda and the well turtle and carried them on his body and left. Five people, one turtle and two bottles of wine slowly disappeared into the night.
