Old man Lin straightened his face and said sternly: "The way of the formation is as vast as the sea, and I have studied the formation for more than 100 years, and I have only seen the tip of the iceberg. If you have the idea of learning something casually in order to defend yourself, I advise you to die of this heart long ago, lest you lose your life in the future. ”

But he left the table. Qianxue stood still, not knowing whether to catch up and apologize.

Lin Cheng on the side saw Qianxue's appearance, and said: "Don't pay attention to that old man, now that the formation has declined, it is a fact, but he doesn't believe it, he still studies it day and night, and he is really stubborn." ”

"I just want to learn some elementary formation knowledge, why is Senior Uncle Lin so angry?" Qianxue said puzzled.

"The formation is different from others, and it is the most meticulous. Two almost identical formations, due to some subtle differences, will lead to completely opposite changes, some beginners who only know one and do not know the other, in the face of the plausible formation, it is very likely to go to the death without knowing it. ”

"In that case, why did the way of the formation decline?"

"Do you think that anyone can study the formation? Those who can understand the true meaning of the formation and innovate and promote it are all people with unparalleled talent and intelligence. Since they are the pride of the sky, they hope to use the power of the formation to overwhelm the monks of their generation. But since the Demon Sect Holy Maiden broke through the five elements of the world, the source of the formation has been extinguished, how can those monks who are superior in both intelligence and temperament be willing to continue to study the formation and be willing to be inferior?"

Lin Chengyi continued: "Without the participation of genius cultivators, the level of the formation is still the same as it was a hundred years ago, and there has been no major progress. Nowadays, if a low-level monk wants to arrange a formation, he only needs to go to Fang Market to buy a formation flag, and according to the instructions, he can lay it down step by step, and there is no need to study it carefully. ”

Listening to the young man talk about this endlessly, Qianxue was unmoved, just because the situation that night was still vivid, if she knew a little about the formation, not to mention breaking the formation, at least she would not inexplicably enter other people's formations without knowing it.

Thinking of this, Qianxue said to the young man: "If I want to learn the formation, what should I do?"

Lin Chengyi pursed his lips and said, "How do I know this? If you really want to learn, you have to ask that old man, and now in the Zhenyi Sect, he is the one who has studied the formation the most." ”

After speaking, he approached Qianxue's side and said mysteriously: "I heard that Senior Sister Luo of Jiuxiao Peak and Senior Brother Li of Jade Emperor Peak met to compete in Qingxin Valley, do you want to go and see the excitement?"

Word by word, she got into Qianxue's ears, she felt that her ears were a little itchy, and hurriedly avoided them, and said, "What do they have to do with me? ”

"Don't you wonder what they are fighting for?" After speaking, he followed the old man's appearance, sitting on the futon, as if you came to beg me.

Qianxue didn't bother to take care of him anymore, so she left the teaching hall and went to Old Man Lin's cave.

When she arrived outside the cave mansion, Qianxue took a note and went in, speaking earnestly, asking Old Man Lin to teach her the way of formation.

After a long time, there was no response, and Qianxue had to go back. Early the next morning, Qianxue went again, but there was still no response. In this way, Qianxue's move gradually spread in the True One Sect, and it was only when everyone learned that the ruthless real person had accepted another disciple, who was personally selected by the Qingzhu Daoist. Many monks who were happy to be quiet stopped outside the door of Old Man Lin's cave mansion, with an innocent gossip heart, paying attention to the development of the situation.

In fact, Lin Shi has not had a good time these days. He naturally knew everything about the things outside the cave, and slowly inquired that Qianxue was actually a disciple of a ruthless real person, which startled him, and he didn't dare to teach Qianxue the formation, to let the Qingzhu Dao people know, he still had to take off his skin?

"Taishang Laojun, Taishang Grandpa, alas, the old man begs you to let Qianxue not come again today. He prayed silently, but out of the corner of his eye, he caught a glimpse of a transmission note running towards him in a hurry, so frightened that he took several steps back before he could stand still.

So, he was finally convinced that if he didn't give a reason to refuse, she would not give up no matter what, and it had to be a very convincing reason. He thought about it for a long time, and finally let him come up with a solution.

One day, Qianxue went to greet Old Man Lin's cave as usual, never thinking that the cave was wide open, as if she was waiting for her arrival. She was overjoyed, thinking that the old man had finally relented and was willing to teach her the formation, so she hurriedly walked into the cave.

Seeing the old man sitting precariously and looking at her with a solemn expression, she felt a pang in her heart, dared to slack off, and hurriedly stepped forward to give a salute.

Old man Lin nodded with satisfaction and said, "Xiaoyou's earnestness to learn the formation, the old way has already understood, but if it is only like this, it is not enough. ”

"But what is missing? If it is a spirit stone, there are still some juniors. Qianxue said busily.

When the old man heard this, his eyebrows raised slightly, and he quickly returned to normal, and said, "Well, learning the formation naturally requires a large number of spirit stones, but it is still the same." This time, he didn't wait for Qianxue to ask, so he said: "The most important thing in learning the formation is understanding, if Xiaoyou doesn't have enough understanding, even if I am willing to teach, it will not be useful." ”

"Senior sister said that I have excellent qualifications, and I must have a good understanding. Qianxue said politely.

The old man remembered the day he first met her, and she also said that she had excellent qualifications, but he didn't take it to heart at the time, thinking that she didn't know the height of the sky, but now he knows that it was Qingzhu's evaluation of her, and her qualifications are naturally good. What if she did pass his test?

After thinking about it again and again, he still followed the plan and said: "It's not up to you to decide whether your understanding is good or not, and the old way won't make it difficult for you, you go back and study this book well, as long as you can see the doorway inside within three years, I will teach you the formation, and I will never regret it." As he spoke, he took out a bamboo slip from the storage bag and gave it to Qianxue.

Qianxue took it, but it was a bamboo slip engraved with "arithmetic".

Spring is going to winter, and Shinyikyo is ushering in a new year.

This year, the True One Sect added many new disciples, many of whom were extremely talented. If you want to talk about the recent news in the True One Sect, it must be a month later. The disciples are all gearing up, hoping to get to the day of the competition as soon as possible and show their strengths. Some people who are interested pay attention to Lingbao Zhai all day long, for fear that a certain treasure will be bought by others.

Old man Lin Shilin was no exception, with a pair of cloudy old eyes, staring at Lin Chengyi and said, "I said what I said before, say it again, if you can't break into the top ten, then don't think about taking another spirit stone from me." ”

"Old man, you can rest assured to earn spirit stones," Lin Chengyi was full of confidence, "Senior Sister Luo and Senior Brother Li fought a defeat that day, and they haven't recovered until now, how can they be my opponents?"

After that, he said strangely: "That girl hasn't been here for more than a year, has she given up? But this is fine, so as not to miss her future." ”

Old Man Lin was silent for a moment, and only said, "Maybe." ”

Speaking of Qianxue, what is she doing now?

It turned out that after the agreement with the old man, Qianxue was very busy every day. At the beginning, she devoted half of her energy to practicing water dueling, and half of her energy to study arithmetic. It wasn't until half a year later that I found that it was useless to leave the water in the decision, although this method can extract the water within a few zhang, but the spell casting time is also a little longer, and the more grooved cake is that the monks are often separated by dozens of zhang, and they are easy to get close.

In this way, she temporarily gave up the decision to leave the water, and concentrated all her energy on studying arithmetic, the more she studied, the more fascinated she became, to the point of forgetting to sleep and eat, she completely forgot about cultivation, and after another year, when she thought that she had mastered arithmetic, her cultivation had only reached the fourth level of qi training.

She got carried away and ran to find Lin Shi and said, "I've learned to pull arithmetic, you can teach me the formation quickly." ”

Old man Lin asked a few questions casually, and when he saw that she could answer them very smoothly, he knew that she had really learned.

So, he said, "I'll just ask you one last question, and if you can answer it to my satisfaction, I'll teach you." ”

"Ask, ask. Qianxue was a little impatient.

"What do you learn from arithmetic, or what do you think arithmetic is?"

Qian Xue didn't expect him to ask such a simple question, and said without thinking: "Arithmetic is naturally a knowledge that studies numbers and shapes. ”

"No, no," the old man narrowed his old eyes, raised his hand, and gave an eviction order, "You better go back and study for another year." ”

Qianxue was not convinced, and wanted to reason with him, but the old man never answered her again, so she had to go back to the nest and study from the beginning.

Looking at the results again, she still didn't change her original intention. This arithmetic book contains two contents, one is dedicated to the study of the structure of numbers, and the other is specialized in the study of the properties of figures.

After thinking about it again and again, she still couldn't figure out the doorway, so she looked through the arithmetic over and over again, trying to find out what she had overlooked.

Time passed silently, and the bustling sect Xiaobi had already fallen into a dazzling scene. The victor is happy, and the loser is depressed.

On this day, Qianxue slept soundly, she dreamed that two balls of light, one black and one white, flew around her happily, and finally merged into one, and suddenly a hideous string appeared, which frightened her into a cold sweat.

When she woke up, she felt as if she had caught something, but when she thought about it, she forgot to clean it up. Thinking back to the situation in the dream, he finally suddenly realized that he muttered to himself: "The crowd looked for her thousands of times, and suddenly looked back, but the person was there, and the lights were dim, and the ancients did not deceive me." ”

After finding the answer, she was not in a hurry, she slowly freshened up, and when her clothes were neatly dressed, she found that she had grown two points taller, which made her a little happier.

Seeing Qianxue's confident appearance, Old Man Lin knew that she must have thought of a very weighty answer, but he didn't think that she could find the real answer, he thought about it for nearly five years, and finally Shizun unintentionally revealed it to him, and he only knew.

"The Tao divides yin and yang, and so does arithmetic. "Senyuki-do.

"Do you want to use mysterious things to fool Lao Dao?" Lao Dao was extremely angry, and he still had something to look forward to.

"Old man, you listen to me first," Qian Xue forgot her honorific title for a while, and said what was in her heart, "Arithmetic is ostensibly a study of numbers and shapes, but if you think about it deeply, aren't numbers and shapes equivalent to yin and yang? Therefore, the essence of arithmetic is what numbers and forms have in common, and what allows them to transform into each other. ”

"What it is. Old man Lin couldn't help but ask, not caring at all about Qianxue calling him 'old man'.

"The essence of arithmetic is immutability. "Senyuki-do.

When the old man heard this, his eyes widened, and he still didn't believe that she had really said it, maybe she just happened to say it?

So, he said, "What do you say?"

Qianxue talked eloquently and said something that convinced the picky old man.
