"In arithmetic, the formulas are ever-changing, and the symbols are very different. However, no matter how complex it is, the ultimate goal of reasoning is only one, which is to portray the immutability buried in the depths. The Pythagorean principle in graphics is a classic depiction. ”

After listening to Qianxue's explanation, Old Man Lin knew very well that she understood the essence of arithmetic, and she had truly stepped on the threshold of arithmetic, and was qualified to study deeper things. So, he spoke: "Your answer is indeed very satisfactory to me, if you are willing, I will teach you the way of formation." ”

These days, she has been thinking about this day and night, how can she be unwilling? Hurriedly bowed her head to worship, but was helped up by the old man Lin, who was at a loss, and only heard the old man say: "Although the old man passed on your formation, he is not your master, so there is no need to make this great gift." ”

Qianxue is good as long as he is willing to pass it on, since the old man doesn't care about etiquette, she is naturally happy to do so, and said: "Please also ask Uncle Shi for guidance, where should I learn the formation?"

"You've entered the Formation Gate. The old man smiled, saw that she was puzzled, and explained: "The essence of the formation is also immutability. In any formation, no matter how it changes, there is always something unchanging, that is, the so-called 'formation', the key point of breaking the formation is to find the formation, on the contrary, the arranger should try to hide the formation. ”

"At the beginning, I mistakenly entered a phantom array full of peach blossoms, and it is always changing, how can there be anything that does not change?"

After listening to Qianxuedi's questioning, the old man was not angry, but a little nostalgic for the past, how long had he not been able to show his profound knowledge? So, he said: "It just seems to be a change, but in fact, there is a certain law behind those changes, and this law is the formation. ”

"Is it possible that there is a formation with endless changes and no formation?" Qianxue wondered.

The old man shook his head and said, "The monk can only arrange the formation as little as possible, but it is impossible to really arrange a formation without a formation. If you want to say that it is possible, I am afraid that only God can do it. ”

"Oh my God?"

"Yes," said the old man, pointing to the stone table, "you said the stone table in front of you is real?"

Qianxue touched the stone table, felt a little cool, and said: "Nature is real, this is not like the peach blossom tree in the illusion array, it looks real, but it doesn't feel when you touch it." ”

"Is it true that what you think you can feel?"

"Isn't it?"

"Let me ask you, if there are two people, one who is particularly spicy and the other is not spicy at all, and they are asked to taste a pepper that is not very spicy, what do you think they will say?"

"Naturally, one said that the pepper was not spicy at all, and the other said that it was very spicy. ”

"Okay, so is this chili pepper spicy or not? So the feeling of spicy varies from person to person, isn't it? In the same way, the sensations of color, flavor, touch, etc., all vary from person to person, so why do you say that what you feel is real?"

Qianxue pondered for a moment and asked, "Isn't there a truth in this world that everyone recognizes?"

"I ask you, if you remove everything that can be felt in the flavor, color, and shape of the chili pepper, what is left?"

Qianxue thought for a long time and said, "Then there is only room left for the chili peppers." ”

Old Man Lin nodded with satisfaction and said, "Yes, this is recognized by the vast majority of formation mages at present, that is, all matter will occupy a certain space, that is, all matter has a wide extension. ”

"Since the feeling is not necessarily real, how can you tell if you are in the phantom array?" Qianxue Qi said.

"As long as it is a formation, there must be a formation, as long as you can find it, it is in the phantom array, if you can't find it, you can only think that you are in the real world. ”

"So, can't this world be just a phantom array?"

"Yes, some of the array mages suspect that all of us are actually living in a phantom array, so they take the trouble to search for the formation veins everywhere, trying to break through the phantom array and return to the real world, but unfortunately they find nothing. ”

Then, he taught Qianxue a lot of formation points and common sense, and finally said: "Now you can also understand the "Introduction to Formation" in the Moral Pavilion, you go and see it first, and then ask if there is anything you don't understand." ”

After listening to this half a day, Qianxue benefited a lot, but she was also a little tired, got up to say goodbye, walked to the door of the cave, and listened to the old man again: "Girl! The road of formation, I haven't studied hard for decades, don't expect to have great achievements, this layer, have you thought about it?"

"Yes!" Qianxue said seriously.

I don't know who the time is, page by page, and in the blink of an eye, it is another three years.

Qianxue's cultivation in the past few years can be described as difficult to move an inch, and she is helpless about it, the higher her cultivation, the greater the energy required for the strings. She worked tirelessly refining the aura every day, but it was just a little bit of growth in the aura in her body. As a result, she became less and less interested in cultivation, and instead devoted herself to studying the formation.

As her research deepened, the materials needed to carve the array flag became more and more diverse. Sometimes, although she has all the materials, a mistake will lead to the lack of a certain material, and she has to buy the material again, which is very annoying.

She discussed with Steward Zhang and posted a miscellaneous disciple who was responsible for sorting out and purchasing materials for her, so that she could devote herself to studying the formation. There are only two difficulties, one is that this miscellaneous disciple is required to be on call, and the other is that he also requires a rough understanding of the formation and knows how to distinguish some formation materials.

The announcement was posted for a few days, but no one responded. It turns out that the reason why the miscellaneous disciples are willing to do miscellaneous labor is nothing more than to earn some spirit stones to cultivate, and when they are cultivating, they must not be disturbed, so the requirement of being on call alone has put an end to the minds of most monks, although the remuneration is much higher than other jobs, and the tempting monks are deterred by the second hope.

In desperation, Qianxue had to increase the price a few more times, and now she only lacks time and spirit stones. After she tripled her pay, she finally waited for someone to respond.

After carefully looking at the female monk in front of her, who looked a little delicate, Qianxue took out more than a dozen materials and said, "Look at it, how many can you recognize?"

The nun only glanced at it twice, then picked up the material casually and said the same: "This is echo grass, this is the broken intestine branch, this is the traceless liquid, this is the ......"

After the female cultivator recognized seven or eight materials in a row, Qianxue was like a treasure, and immediately said, "What's your name, when can you come?"

Who knew that the female cultivator said: "I'm Mo Qiuping, but you still have to promise one thing, so I didn't consider whether to come." ”

"What's the matter?"

"I also have a younger sister, Mo Qiuxin," Mo Qiuping hesitated for a moment, then said, "I hope that Uncle Shi can let our sisters live together to the peak of ruthlessness." ”

Qianxue is fine as long as she is willing to come, so what does it matter if there is one more person?

In this way, Qianxue was finally able to close the door and concentrate on exploring the formation, and let Mo Qiuping be responsible for sorting out the required materials. Gradually, even the affairs of Ruthless Peak were handed over to Qiu Ping, almost isolated from the world.
