Mengniang martial arts world

(This is the second update of today's guarantee, but it is actually the third update.)

When Ying Gu heard this question, one head was bigger than two.She quickly took out the counting chips she carried with her and calculated: "Each soldier has three more dou, the fifth soldier has fifteen dou, the sixth soldier has eighteen dou, the seventh twenty-one dou... the eighth twenty-four Dou..." She counted down one by one, and after a while, a few strands of her hair turned gray again, and she was dripping with sweat.

After a long time, she only counted fifty soldiers, and she was already sweating profusely.

Li Yan smiled and said: "You can't do this. This is an arithmetic progression problem. There is a difference of three buckets of rice between every two soldiers, and there are 180 intervals between 179 soldiers, that is, 179 multiplied by 3. A soldier starts with 3, so the final answer is 179 times 3 plus 3, and the final answer is 540, which is 540 buckets of rice."

As soon as these words came out, Gu Ying was shocked, she hurriedly followed Li Yan's train of thought to think again, and she suddenly understood, there was no need to add them one by one, as long as she found the pattern, it would be easy to solve.

She exclaimed in surprise: "Arbitrariness series... This is a new numerology term, I have to write it down quickly. Arithmetic series can be easily obtained by multiplying the interval number by the difference, clever, really incomparable clever……"

Speaking of this, she glared at Li Yan, and said with a snort, "You know this arithmetic sequence, but it's not necessarily better than the arithmetic in "The Picture of Heluo". This question alone is not enough to prove anything."

Li Yan wanted to impress her, so he smiled and said, "Then let's change the question a little bit. The question is still the same as before. Give the soldiers rice, but the question now is not how many buckets of rice should be given to the 180th soldier, but how much rice the 180th soldier should give out. ... How many meters do we need to distribute for all [-] soldiers?"

When Ying Gu heard this, her expression changed drastically, she turned a corner in her mind, and said tremblingly, "The first soldier has three fights, the second soldier has six fights, and three plus six equals nine. The third soldier has nine fights. Nine plus nine equals eighteen. The fourth soldier is twelve, and eighteen plus twelve equals thirty..."

She counted for a while, and she only counted twenty or thirty soldiers. After dozens of additions, one head became two bigger, sweating profusely, and a few strands of gray hair.

She couldn't help but said to Li Yan: "This... isn't this kind of question a tosser? Just now, I only calculated how much rice the 180th soldier needs to send. You can quickly calculate it with the trick you mentioned, but this time the 180th soldier needs to be paid. Adding up all the rice, it’s impossible to have a trick, right?”

Li Yan laughed and said: "Of course there are tricks, this is called 'Summation of Arithmetic Sequences', there is a formula available, as long as you substitute that formula, you can quickly get the answer, if you teach me loach kung fu, I will teach it All the arithmetic formulas you and I know are guaranteed to be much more useful than this "Picture of Heluo", do you believe it?"

Ying Gu and Li Yan met for the first time, how could they trust him so easily?She still believed in "The Picture of Heluo" more, hesitated for a while, and hesitated. .

Li Yan opened "The Picture of Heluo", opened to the page of Jiugongge, and then drew a picture of Jiugong on the ground with a charcoal pencil. The so-called Jiugongtu is actually a number-filling game. In the nine grids, it is necessary to ensure that the sum of the three horizontal, vertical and oblique numbers is equal.

Li Yan smiled and said: "This is a relatively advanced topic in Jiugongge, the map of Heluo."

Ying Gu quickly nodded and said: "That's right, this is also the most important calculation problem in deducing the changes of formations. If you can master the Jiugongge proficiently, you can easily handle any complicated Qimen and Five Elements formations. All changes in the law, so that you will not be trapped by the formation."

Li Yan said with a smile: "This is just a children's problem. Come on, let me show you something more interesting." After speaking, he drew a huge table on the ground with charcoal, including nine nine-square grids. There are nine squares in total. Nine 81 grids.

Seeing so many grids, Yinggu immediately panicked, and shouted, "What kind of problem are you doing? Why did you draw nine grids?"

Li Yan said with a smile: "This is called 'large number reading'. On the basis of one nine-square grid, it is expanded into nine nine-square grids. Numbers from 1 to 9 must be filled in to ensure that each horizontal column and vertical column has 123456789. number, cannot be repeated."

Ying Gu was stunned: "This...is... so difficult?"

Li Yan said with a smile: "It's not difficult, it's just a very simple question. If you can read the numbers well, you will be able to understand all the changes in the Jiugongge. Then no matter what five-element formation, no matter how it changes, You won’t be troubled. In fact, counting is not arithmetic at all. If I teach you seriously, the sum of arithmetic progressions is just a small problem. After you learn all the magic formulas of hyperbola and parabola, no matter what Any formation, in your opinion, is nothing more than commonplace."

Ying Gu was overwhelmed by the huge reading table. She finally believed that the arithmetic recorded in "The Map of Heluo" was not as good as Li Yan's. Without any hesitation, she bowed down to Li Yan and said excitedly. : "I'm looking for my brother to teach me arithmetic..."

Li Yan said with a smile: "Okay, okay, Senior Sister Yinggu, you can go back first. From now on, every evening after school, you come to my dormitory, and I will teach you a class of arithmetic."

Ying Gu was overjoyed, thanked Li Yan quickly, and went happily. Before leaving, she took a piece of paper and copied back the number reading that Li Yan had drawn on the ground. This number reading question seemed to be enough She is happy.

Li Yan thought to himself: She studies arithmetic so hard, is she also going to Peach Blossom Island to break the organ formation and rescue the old naughty boy Zhou Botong?Probably not, my intuition tells me that Zhou Botong is a woman.

It's useless to think too much, Li Yan took the hand of the girl with ponytails, and seriously searched for the cheats he wanted to learn.

There are not many cheat books on the high-level martial arts bookshelves. Compared with the low-level and intermediate-level bookshelves, they can only be described as sparse. It can be seen that the more advanced martial arts, the less!Most of the kung fu is mediocre and ordinary, and it is far from advanced.

Li Yan saw a secret book of "Capturing Dragon Kungfu" in front of him. This is a kind of kung fu of extracting objects from a distance, which is quite powerful. In the book "Ba Bu of Tianlong", Qiao Feng used the skill of capturing dragons before. , With just one wave, the enemy's weapon flew into Qiao Feng's hands, it was really cool, it could be said to be a kind of unreal kung fu.

Li Yan thought to himself: Firstly, this kung fu is fun to play, and secondly, it is also very suitable for girls with ponytails. She and I can practice together, so we might as well borrow it, so he put this cheat book in his arms.

In a blink of an eye, he saw the Quanzhen swordsmanship on the shelf next to him. Li Yan thought: I am practicing Quanzhen internal strength, but I have never practiced Quanzhen swordsmanship. If this set of swordsmanship is combined with Quanzhen internal strength, theoretically speaking , should be much more powerful than Songfeng swordsmanship, you might as well borrow it to learn it, so I reached out and took it down.

In the end, there was still a quota, so Li Yan began to worry about gains and losses. Looking at the shelves full of good books, he didn't know which one to borrow.At this moment, he suddenly thought of Ying Gu who had just left, and he couldn't help but think: Ying Gu learned arithmetic to learn the formation of "Qi Men Wu Xing". is fake.But in the martial arts world, it's unmistakably true.For example, Peach Blossom Island has formations. In the book "The Legend of Condor Heroes", Huang Rong also used small stones to form formations to resist the enemy.

For ordinary martial arts practitioners, the Qimen Five Elements is very difficult, and they can't even get started, because the Qimen Five Elements need mathematics as a foundation, but most of the ancient people's mathematics is very bad.Looking at all Jin Yong's martial arts novels, only Huang Yaoshi, Huang Rong, Ying Gu, and Cheng Ying studied mathematics intensively, and the others may not even be able to do multiplication and division well.

But for the full-score man Li Yan, Qimen Wuxing is an easy thing to learn, because the mathematical foundation of the full-score man is much better than that of people on this plane. He is sure that even if Huang Yaoshi sits in front of him, He can solve math problems together, let alone Huang Rongying or something.If they can learn Qimen and Five Elements, then Li Yan will definitely be able to.

For Li Yan, who lacks skills, many advanced martial arts cannot be practiced, such as supernatural powers, Li Yan is absolutely unable to practice now, but Qimen Wuxing does not need the foundation of internal skills, as long as he can calculate Yin-Yang and Five Elements, he can master them proficiently .

After making up his mind, Li Yan searched the bookshelf for a while, and finally found the book "Qimen Five Elements" in an inconspicuous corner. Obviously, this book has been neglected for a long time, and a thick layer has accumulated on the spine of the book. The thick dust, Li Yan took it off, blew away the dust, held it in his hand and couldn't put it down.I thought: as long as I learn this, I can also fight against opponents who are much stronger than myself like Huang Rong. Even if I can't beat them, I can defend with a formation.

The ponytail girl was happy seeing him, and she was also happy: "Student Li Yan, have you chosen? Let's go to the librarian to register."

Li Yan nodded and said with a smile: "I have chosen, let's go, let's go find Miss Wang Yuyan."

The two of them searched around the Sutra Pavilion, searching every corner, but they still couldn't find Wang Yuyan. The ponytailed girl couldn't help but wonder, "She didn't go to the bathroom, did she?"

Li Yan shook his head: "It's strange, she wasn't there when we came. We discussed with Ying Gu and looked for the books I wanted to borrow, which wasted a lot of time. Let alone go to the bathroom, she has finished washing even after taking a shower." ? Why haven’t you come back yet? This is a strange thing.”

The ponytailed girl's face suddenly turned red, and she whispered, "Isn't she hiding in the grove to have a tryst with the boy she likes?"

Li Yan sweated profusely: "Wow, if Wei Xiaobao said this, I would think it's normal. Why would you say such a joke?"

The girl with the ponytail blushed like blood. It turned out that she thought of herself. She used to practice boxing in the grove, and she could be found in the grove at any time, but recently, as long as she is not in the grove, she is always around Li Yan. , That's why she misunderstood Wang Yuyan's matter.

Li Yan thought of the name Murong Fu, and thought: what the girl with the ponytail said might have a surname, maybe Wang Yuyan really went to have a tryst with Murong Fu.

He looked around and saw a dense forest behind the Sutra Pavilion, so he said to the girl with ponytails: "Let's go, let's go to the small forest and see if she is really having a tryst with a man."

Diary of a lonely man:

I used to be so lonely, without a friend, without a confidant.

But when I came to this plane, inadvertently, I already had a large group of friends, and even my first woman.My life has turned upside down, it is no longer gray and white, but colorful.

I found that after having more friends, the trajectory of life will change accordingly, and there will be more things to do.Because I am no longer alone.While I take care of myself, I also take care of my friends.

I worry when they do something dangerous.When they are sad, I am sad too.When they are in trouble, I want to help them.When their fate is heading towards the abyss of destruction, I will use all my strengths to reverse their tragic fate.

For this, I need strength!More power!

Li Yan
