Lu Ru asked, "Since you don't agree, is there a good way?"

"Do you remember the method of borrowing shapes in fractal geometry?"

"I understand!" Lu Ru pondered for a while, looked up and saw the distant stream coming from the top of the mountain, and then disappeared into the mountains, and suddenly realized, "You mean, through the form of the whole, to gather strength in parts, to make up for the lack of power of the water line to turn into Xuanwu?"

Mo Xian smiled slightly: "That's right, if this formation is analyzed by arithmetic, there are indeed many problems, but in terms of classical formation, it is relatively perfect." Pen Fun Pavilion wWw. ｂiquge。 ｉｎfo”

The more he listened, the more confused he became, and asked, "You say this array is imperfect, what is the fractal geometry?"

Lu Ru explained: "Sister, fractal geometry is a branch of arithmetic, and arithmetic is the study of all numbers between heaven and earth, Mo Xian came back this time, learned a new method of cultivation, called instrument cultivation, take the metaphysical way, metaphysical means of instrument, instrument cultivation is a kind of cultivation to discuss the laws between heaven and earth, and arithmetic is very useful for the formation of methods. Sister, you see, if the crooked stream is abstracted into a line, you will find that each part is very similar to the whole, and the part seems to be a projection of the whole, which is the category studied by fractal geometry, and the application in the formation is to call the whole with the part. ”

Lu Yi looked at it for a while: "It seems to be a bit similar, but how to use the power of the whole?"

"The power of heaven and earth, as long as the key is grasped, for fractal geometry, any part can represent the whole, and the four elephants are full of water to achieve Xuanwu, only calling a part of the entire stream, but not thinking of extending it to the entire basin, just seeking the same qi. Mo explained with a smile.

Lu Yi lowered his head and thought for a while, raised his head, and punched out a string of seals in his hand, and suddenly the stream vibrated and the water fluctuated, but unfortunately, Xuanwu had just taken shape, but it dispersed.

In my mind, the whole stream is inseparable, and then the part is regarded as the whole, and then the part is the whole, and it is placed in the wild, collected in the hidden, and back and forth freely, so as to be able to collect and release freely. Mo Xian said.

Lu Yi suddenly, tried more than a dozen times in a row, and finally in the last time, the Xuanwu phantom was formed, roaring and blending into the formation, the formation changed, becoming a little unfamiliar, a layer of water vapor rose in the four elephants in the heavenly array, and after a while, it was dry again, but in their eyes, the aura of the formation was flourishing, and then the aura was dispersed, the air was already very fresh, and now there was more spirituality in the air. Although the aura in a stream is not concentrated here, there are two or three here, which of course will cause changes.

Lu Yi was overjoyed at first sight, the increase in aura is a good thing after all, and this array actually has the effect of gathering spirits, Mo Xian didn't expect this, but after thinking about it, it is also reasonable.

Lu Ru once again fine-tuned the layout of the array, originally this array was based on the four elephants, and the four magic weapons were placed in the four elephants in the array, and the adjustment of Lu Ru combined the earth qi with it. After fine-tuning, the formation was integrated, three or four times stronger than before, and most importantly, the flaws in the formation were not visible at all now.

Lu Yi and Lu Ru were talking on the side, Mo Xian stood in front of the window, the window was open, looking down from the upper floor, full of green mountains, it was peaceful here, it was a paradise. Mo Xian retracted his gaze, the space was pasted with paper, Mo Xian remembered the glass of the world of instrument cultivation, and in the current world, except for natural crystal, there is basically nothing that can be used to cover the window.

Instrument cultivation is to integrate cultivation into life, and magic weapons are almost everywhere, if you want to promote instrument cultivation in this world, is it also the case, Mo Xian saw the little foxes shaking their heads and reciting the classics, and an idea popped up in his mind.

A few days later, a little fox held a bowl, this bowl looked similar to the bowl outside, but if in the eyes of the cultivators, Yingying radiated aura, its material was just ordinary porcelain clay, but after the fox's demon fire forging, it could preserve food for a long time and gather spiritual energy, but other than that, there was no other use. For cultivators, it's just a plaything.

Mo Xian took it in his hand, praised it in his mouth, the little fox turned into a child, his face was red with excitement, in fact, he was not the only one, many little foxes took out their own works, there are bowls and plates, as well as vases and other things, and even the image of cute little animals, Mo Xian did not hesitate to praise, and pointed out the corresponding shortcomings, but the big Confucian was a little unhappy, full of gentlemen, strange skills and clever words, Mo Xian just smiled, did not care, the well frog knew the width of the sky.

When Lu Ru saw it, he said, "Do you plan to cultivate them with the method of instrument cultivation?"

"No, your sister taught them very well, I just taught them some instrument cultivation skills, they use demon fire, play these tricks, will be very interested in this, on the one hand, they have exercised demon fire, on the other hand, they have an understanding of physical properties, to see if they are smart. Mo Xian said.

There was another little fox holding a piece of glass in his hand, and Mo Xian's expression moved: "What's your name?"

"My name is Hu Jia, when I burned that kind of soil, I finally got this thing, Master Mo, look at what this is?" Hu Jia said.

"Yes, this is Liuli, you burned Liuli, do you remember your recipe?" Mo Xian asked.

"Remember!" Hu Jia said after thinking for a while.

"Very good, after you go back, use mana to separate the impurities in the raw materials, until you refine the colorless and transparent glass, well, you can call it glass, think about it, if it is used on the window, what kind of scene it will be!" Mo Xian said, although he knew the formula of glass, he didn't want to say it directly, if she could discover it by herself, she would discover it by herself, and the way of instrument cultivation was not in glass, but in exploration.

A few days later, the color of the glass in her hand became lighter and lighter, and Mo Xian knew that the impurities in the glass would decrease, no matter what, a person with mana is much stronger than ordinary people, ordinary people can only use instruments to separate impurities, and even cannot separate, but a demon with mana can do this, and he can completely rely on his mana to do this.

After Mo Xian left, although this place was in the Four Elephants Heavenly Array, but a few years later, those dishes, toys and glass flowed into the people with the Great Confucianism, becoming excellent boutiques, and even became the offerings of the palace, and the price soared again and again, so the world spread the saying of immortal porcelain and immortal crystal.

Mo Xian and Lu Ru stayed here for a month, then set off to the location of the Holy Gate, the Holy Gate settled in Luoshan, although the loss was great, many Yuan Shen, Yuan Ying and Jin Dan were killed in battle, but the foundation is still there, this catastrophe has made the three doors and three halls together, and the barrier between the free sky, the other heaven and the sky disappears.

The sect is located in Guiyan Peak, and today Guiyan Peak can be described as a layer of fortification, the aura of the formation is flickering, outsiders are here, it is difficult to move an inch, but in Mo Xian's eyes, it is full of flaws.
