"That's fine!" Seeing Qiu Qianzhang go away, Hong Qigong sighed, that Qiu Qianzhang is not easy to get along with, if he comes directly to ask for "Wu Mu's Testament", he is afraid that he will not give it, if it is a fight, no matter who wins or loses, it is a grievance, it is better to let Qiu Qianzhang quietly take things away, so that it can save some entanglement.

After Qiu Qianzhang left, everyone continued to walk, and the next day they arrived outside a forest, Huang Rong looked up from Guo Jing's back and said, "Brother Jing, go to the right front obliquely." ”

Guo Jing walked diagonally to the right front according to his words, Huang Rong silently counted his steps, and when he counted to ten steps, he said, "Take eight steps to the left." ”

Guo Jing did as he said, and Huang Rong said again: "Take another ten steps diagonally to the right." One pointed, the other followed, and the two of them walked in the zigzag of the woods where their fingers could not be reached, while Shen Long and Hong Qigong followed behind them.

This Qimen Dunjia technique is somewhat interesting, when Huang Rong is healed, I want to learn from her, if I have the opportunity to go to Peach Blossom Island in the future, I have to ask Huang Yaoshi to inquire clearly; Shen Long is not lacking in martial arts now, in his opinion, the martial arts in "The Legend of the Condor Heroes" only "One Yang Finger" and "Innate Skill" can make him a little interested, and now when he saw the formation laid by Aunt Ying at the door, he suddenly remembered that this knowledge may come in handy.

Sometimes to the left, sometimes to the right, sometimes to the backwards and diagonal steps, as if the journey is more and more circuitous, how do you know that before a tea hour, a vast white mist in front of you wraps the two huts, and outside the huts is a dark and swarthy swamp; Huang Rong observed for a moment and asked Guo Jing to do as he said, and Guo Jing stepped on the wooden stake in the mud to the door of the thatched hut.

"In the past, the guests took the liberty to enter, but it was really a last resort, and I still ask the virtuous master to be generous and tolerant." After saying that he stopped for a while, he walked into the hall, only to see a long table in front of him, on which there were seven oil lamps, arranged in the shape of Tiangang Beidou, although it was daytime now, but the indoor light was dim, the oil lamp was still on, and there was a gray-haired woman squatting on the ground, wearing a linen shirt, staring at the countless pieces of bamboo one by one on the ground, obviously thinking about himself, although he heard someone coming in, but he did not look up.

Shen Long and Huang Rong looked at the same time, and immediately recognized that this was the calculation chip for doing arithmetic, and secretly counted the number of operators, knowing that she was calculating the square root of fifty-five thousand two hundred and twenty-five, at this time, the "quotient" position had been calculated to two hundred and thirty, but seeing that the old woman was playing with the operator, she was about to calculate the third digit, and without waiting for Huang Rong to speak, Shen Long blurted out, "Five!" Two hundred and thirty-five! ”

This knowledge is considered a great knowledge at the moment, but in the later generations, it is only at the level of junior high school students, Shen Long inherited the talent of Ivan Vanke, how could someone who understands mechanics and physics not be proficient in mathematics, so he can see it at a glance.

Aunt Ying fiddled around for a while, and sure enough, she calculated that it was "two hundred and thirty-five", looked up and glanced at Shen Long again, the look of surprise on her face quickly disappeared, and she saw her angry face again, as if to say, "It turned out to be a kid, you just guessed by chance, why is it strange?" Don't bother me here. Shun wrote down two hundred and thirty-five on the paper, and calculated the next arithmetic problem, this time it was to find the cube root of three thousand four hundred and one thousand two thousand two hundred and twenty-four, and as soon as she put the calculation plan down, Shen Long said, "Three hundred and twenty-four." ”

At this time, not only Aunt Ying and Huang Rong were surprised, she had just counted the hundreds; Aunt Ying was willing to believe it, and calculated the result after a cup of tea.

"If it's a prescription, you can use the Tianyuan Technique!" Shen Long picked up an arithmetic chip and drew the formula of opening the square and opening the square on the ground, the so-called Tian Yuan Shu is the ancient Chinese method of solving equations, he replaced the modern mathematical symbols with the symbols in Tian Yuan Shu and showed it to Ying Gu.

Ying Gu looked at it for a long time, brought the two numbers just now into the formula, and found that the speed of the operation was really much faster than her just now, her eyes stared at Shen Long, and she suddenly pointed to the inner room, and said, "Follow me." He picked up an oil lamp and walked in.

The people followed in, and saw that the walls of the inner room were surrounded by a circle, and the ground was covered with fine sand, and many horizontal and vertical symbols and circles were drawn on the sand, and some words such as "Tianyuan", "Diyuan", and "Renyuan" were written; Guo Jing and Hong Qigong didn't know what to do, for fear that they would break the runes on the sand, so they stood at the door and didn't dare to enter.

Shen Long took a look, this is the Tianyuan technique he just showed, these problems that have plagued Ying Gu for a long time are just some simple one-dimensional quadratic and two-dimensional quadratic equations, as long as the junior high school mathematics can be passed, it can be easily solved, so he stepped forward and gave the answers one by one.

Aunt Ying pondered these arithmetic questions for several months, but did not get a solution, so she couldn't help but be surprised, stayed for a long time, and suddenly asked, "Are you human?" ”

"What's the point?" Not to mention the scientific literacy of Ivan Vanke and Lao Bai, how can I say that I am also a person who has studied advanced mathematics in college, and you use junior high school mathematics to rely on me, isn't it too underestimating people?

"Your algorithm is naturally a hundred times more accurate to me, but I ask you: how to arrange the nine numbers from one to nine in a column, regardless of the vertical and horizontal oblique, each word adds up to fifteen, how to arrange it?" Aunt Ying asked again.

"Haha, this one is even easier!" Primary school Olympiad mathematics does not test these questions now, "There are four solutions to this problem..... Hey, this is a little familiar, it looks like Kong Yiji.

Daddy just came up with one, and he saw four at a glance, Brother Yang is not only strong in martial arts, but also in arithmetic.

Jiugongge can be regarded as an interesting Sudoku game, since Aunt Ying gave herself a problem, Shen Long was not polite, and directly took out many Sudoku variants, such as diagonal Sudoku, mini Sudoku, diagonal Sudoku, Siamese Sudoku, killer Sudoku, etc., which made Aunt Yinggu stunned.

"It's just a little bit of a trail, it's not worth mentioning at all." Shen Long brushed on the sand and wrote the big killer, but it was the calculus co-founded by Leibniz, the great sage of the Taixi Apple Tianzun Newton, the maniac of the forehead integral, and the emergence of calculus officially distinguished classical mathematics from modern mathematics, leading mathematics into an unprecedented period of prosperity.

At the same time, a seed was planted, and this seed would grow into a tree called Gaoshu, and the tree was covered with the corpses of countless scholars, so that many people hated Newton, Leibniz, Cauchy, and others when they heard them.

If Aunt Ying only admired Shen Long's subtlety of arithmetic before, now seeing this scene, Aunt Ying was like being struck by lightning, and she opened her mouth wide and couldn't make a sound for a long time, although she couldn't fully understand this, but just a glimpse of the harvest had already numbed Aunt Ying in shock.

Hehe, compare math with me? It's not that I said, if you want to talk about martial arts, there may be a few tricks that can beat me in this world, compared to mathematics, if you call all the mathematicians in the world, I'm afraid it's not enough to fight!
