At this time, there was a breeze in the rockery, and the white fog seemed to have dissipated.

Cheng Linzhi sat there, her beautiful eyes flickering, as if her mind was still immersed in the thrilling chess game of Fang Cai.

Zhang Di coughed and reminded: "Miss Cheng Er, this game of chess has been cracked, can you pass the test?"

"Ah!" Cheng Linzhi blinked, only then did she come to her senses, her eyes swept over everyone present, and she saw that the faces that were still standing were quite normal, and there were more than a dozen people, and the rest of the people couldn't withstand the impact of the gods and ghosts on their thoughts, and they either meditated cross-legged, or their faces were ugly.

Cheng Linzhi groaned, got up and saluted Zhang Difu, and said with a toothy smile: "This exquisite chess game handed down by my father can be cracked by Wang Gongzi, which really makes the little woman feel grateful in her heart, if my father knows, I'm afraid he will also be very happy, right? Please accept the little girl's gift." ”

"Don't dare to be, it happened to be cracked in the next, Miss Cheng Er doesn't have to be polite. Zhang Di stepped forward to help her up, and his hands touched her silky and warm wrists, and he didn't feel a wave in his heart.

I saw Cheng Linzhi's face turn red, and she hurriedly withdrew her hands, raised her eyes and looked at Zhang Di deeply, and said, "Wang Gongzi has passed the test and can go to the next level through the stone beam, please!"

Zhang Di pondered for a while and said, "Can Uncle Lu, the attendant below, bring it over, he just protects me and does not participate in the selection of a son-in-law." ”

Glancing at the tall and mighty old donkey's head, Cheng Linzhi smiled and said: "This is naturally possible, Wang Gongzi's attendant previously relieved the siege for the little girl, and he must also be a hero, let him accompany Wang Gongzi to the next level." The little woman is also more relieved. ”

The words were full of warmth. Jean Zhang touched his nose, a little embarrassed.

He didn't say much. Arched his hand to Cheng Linzhi, and then took the old donkey's head through the stone beam to the front, passing by Linzhi's side, smelling a fragrant fragrance that invaded the heart and spleen, Cheng Linzhi's face was slightly red, and his eyes were shining as he passed by, and the atmosphere was quite ambiguous.

Seeing Zhang Di and the two passing, Cheng Linzhi seemed to look at him differently, and everyone else shouted: "Miss Cheng Er." Ten people have been selected to pass the test, and there are still eight places! Let me go too!"

Cheng Linzhi withdrew his gaze from Zhang Di's back, glanced at the others present, stretched out his finger and said, "Please pass the Xiaoshan faction and Min Yuezong's Xiao Gongzi and Zhao Gongzi! This Jin Hongming and Master Bai will pass the test, and Lu Fei and Lu Gongzi will ......."

Pointing at random, they are all people who have just participated in the chess competition, in addition to these people, there are three other people, all of whom look slightly better in the face of the chess game. It can be regarded as withstanding the test of the gods and ghosts.

As for Xing Bin, who had been accompanying Zhang Di in, he had no chance to come back, so he could only watch with regret and admiration as Zhang Di's back disappeared into the fog, and he looked up to Zhang Di a lot in his heart.

......

Zhang Di cut through the mist. After walking through the stone beam, the scene in front of me changed, and I came to a flower red willow green. There is a small courtyard with a babbling stream flowing around.

I saw a man about fifteen or sixteen years old, dressed in a green coat. A beautiful girl with a bit of coquettishness is squatting on the ground with one hand on her cheek. In the other hand, he held a bamboo stick and wrote and drew on the sand in front of him, and he still had words in his mouth.

Zhang Di's divine thoughts have been greatly enhanced at this time, comparable to a monk in the middle stage of foundation building, but as soon as his mind moved, he heard the girl say clearly: "Cutting twenty-four goblets thinks that forty-eight goblets are the technique: also make the radius a string, half a side is a sentence, and seek shares for it." Put on the small string curtain, four and one, and get 1,737,787,366?"

With a sweep of his eyes, he saw clearly the dense formulas and symbols written on the sand flat, and he couldn't help but sigh, and saw that the girl was calculating some kind of extremely cold and obscure arithmetic problem.

Zhang Di originally studied hard under the teaching of the second uncle, and was no stranger to arithmetic, and after joining the formation hall, in order to study the formation, he also studied all kinds of mathematical knowledge all day long, because the layout of the formation requires accurate calculation, so that the formation materials can play the maximum effect, and simulate a trace of the rules of heaven and earth.

What's more, since Zhang Di cultivated the Demon Dao Distraction Dafa, his divine thoughts have been divided into four, and then into eight, and now he is divided into thirty-six divine thoughts, and his ability to deduce arithmetic has been greatly enhanced!

So as soon as he saw the girl's calculation, he blurted out directly: "Cutting twenty-four goblets thinks that forty-eight goblets are the technique: also make the radius a string, half a side a sentence, and ask for shares for it." Put a small string curtain, four and one, get 1,737,787,366 suddenly, and the rest is abandoned, that is, the power of the sentence. To reduce the chord power, the rest, open the square to divide, to get nine inches, nine minutes, one centimeter, four millimeters, four seconds, four flickering, five cents, four flickering, five cents, flickering, four. In order to reduce the radius, the remaining eight centimeters and five milliseconds and five fifths of a second are called small sentences. The half of the goblet is also called a small strand. Ask for a small chord for it. Its power is 17,112,278,813 and the rest is abandoned.

Divide the square square, get the small string one inch, three points, eight millimeters and six flickers, and the rest is abandoned, that is, one side of the forty-eight yao. Multiply it by a radius of one foot, and multiply it by twenty-four, and we get a power of thirty-one thousand, three hundred and ninety-three thousand, four hundred and forty-four million. Divide by 10 billion, and get 584 of 313 inches and 625 minutes, that is, the power of 96 inches. ”

When the girl heard someone speak, she looked up, only to see a pair of bright big eyes flickering, and when she heard clearly what Zhang said was actually the result that she had been trying to solve but could not get, she screamed, jumped up, ran to Zhang Di, grabbed his sleeve and ran to Shaping, and said: "Hey, hey! You can help me calculate, I have solved this problem for a month, and I can't figure it out, you can help me!"

Zhang Di couldn't cry or laugh, he didn't expect this girl to be so innocent and romantic, she didn't ask who her surname was, she just pulled her sleeves and rushed to Shaping, and she couldn't help but feel a good feeling in her heart.

He didn't talk nonsense, took the bamboo stick handed by the girl, walked to the blank space next to the sand ping, groaned slightly, waved the bamboo stick, and swooped on the sand ping, and soon formulas and symbols jumped out.

Seeing that the girl's eyes were shining, she said continuously: "Yes, yes, yes, why didn't I think of ......this? How can this be counted? I'll have to do the math again!"

At this time, the fog outside the small courtyard flashed, and other people who kept passing the test walked out, Xiao Gongzi, Zhao Gongzi, Jin Hongming, Master Bai, Lu Fei......

When they saw a cute green-robed girl squatting with Zhang Di, the two of them were next to each other, their heads touching their heads, and they were writing and drawing on the sand with bamboo sticks.

Note: The text cites the circumcision technique (or limit theory to calculate pi) of Zhang Cang's "Nine Chapters of Arithmetic" in the Han Dynasty, which is nearly a thousand years ahead of foreign countries. borrowed in Xianxia novels, I hope it will not bring a sense of disobedience to everyone.
