Gongsun Chang's expression was funny.

As a monk who builds the god realm, although he is not good at fighting, but because he is an excellent formation master, his use and control of aura is definitely the most exquisite among the monks, so he can easily see that Su Qi is at ease with the use of aura when drawing formations, and the cooperation of the two spirit pens is also very smooth, each formation pattern is extremely standard, and the most important thing is that his formation pattern is perfectly integrated with the surrounding terrain.

This is not something that a beginner can do, even many formation masters who have been immersed in the formation for many years can not do this, although their formation patterns run without hindrance, but they always do not fit perfectly with the surrounding terrain, there are more or less flaws, the ability of the formation can often only play seven or eight percent, some excellent formation masters can do ninety, such as Gongsun Chang and Sanhao Daoren, such as the top formation masters, can naturally do ninety into nine, and it is actually no problem to say that it is ten percent.

And Su Qi turned out to be similar to them at this point.

This made him very surprised, because the fit between the formation pattern and the terrain not only requires the formation master to have a deep understanding of the formation, but also requires the formation master to have enough experience, abrupt rocks, deep potholes, and the river in front of him, how to draw the formation pattern on these different terrains without affecting the structure of the formation, this is a difficult problem to deal with, and it often takes a formation master to practice for many years to solve.

Gongsun Chang and Sanhao Daoren glanced at each other, and they both saw the accident in each other's eyes, Sanhao Daoist squinted his eyes, his mouth towards Su Qinu, and secretly gave a thumbs up.

This represents his approval.

Gongsun Chang and the three good Taoist friends for more than 100 years, both of them are familiar with each other's character and habits, in the eyes of many people, he is the one in the duo who is not good at talking, but in fact, people who are familiar with them know that it is the three good Taoist people who are really difficult to get along with, this is always smiling round fat man, in fact, he is a proud person, for those who look down, although he will also greet each other with a smile, but in addition to greeting, he is not even bothered to say a good word, especially in the formation, there are very few people who can get his approval, as early as when the two have not joined the Tianji Pavilion, the three good Taoist people often sarcastically and refute other formation divisions at the assembly of the formation divisionIf anyone makes a mistake in front of him, he will be scolded by him for being a fool and an idiot.

This Su Qi is much more powerful than he imagined.

Gongsun Chang thought silently, before Dao Yu handed over the matter of setting up the formation to them, he also mentioned it, saying that the Eight Desolation Peak Lord of the Sword Gate was also a formation master, and he might come over to help, although the two of them agreed, but at that time they just thought that Dao Yu was tactfully asking them to guide Su Qi, for the sake of the face of the deputy pavilion master, they naturally had no opinion, thinking that it would be good for him to watch honestly on the side, but they didn't expect an unexpected surprise.

Although this corner of the Emperor Array is also extremely exquisite, but for Gongsun Chang and the others, it is actually very easy, Gongsun Chang is only in control of a spirit pen, so he has time to pay attention to Su Qi's movements, after Su Qi showed an amazing level of painting array, Gongsun Chang's curiosity about him has become stronger, after all, they don't have such a level at this age.

This attention is frequent, Gongsun Chang sees more and more things from it, Su Qi's technique of painting the array is called double hook, which is a special means of luck for manipulating two spirit pens, this Gongsun Chang is not surprised, the double hook technique is almost every formation master must learn, what really surprised him is Su Qi's decisiveness and speed when drawing the formation pattern, as if in Su Qi's eyes, how to modify the direction of a formation pattern is just something that can be judged in an instant, you know, he and the three good Taoist people can do this rely on many years of experience.

Glancing at it silently, Gongsun Chang finally couldn't bear it, he could become a formation master, naturally he had an extremely strong curiosity about the formation, he flew to Su Qi's side, and the attitude between his words was much more cordial than when he first met, mixed with a little respect, he asked softly, "Lord Su Feng...... I see that when you draw the formation, you modify the formation pattern very quickly, how did you do that?" After he asked, he seemed to feel a little speechless, touched his beard, and said with some embarrassment, "Of course, if this is some kind of secret method, it is inconvenient to talk about it......"

"There's nothing you can't say," Su Qi smiled, and the Sanhao Daoist not far away also pricked up his ears, "It's just simple geometry." ”

"How many, what box?" Gongsun Chang looked dazed.

"Hmm......" Su Qi smiled dumbly, he thought for a while, and then asked, "Let's ask Mr. Gongsun a question first, craftsmen often use rules and rules, rules to draw circles, moments to draw squares, if I have a moment in my hand, one side is three inches long, and the other side is four inches long, at this time, if I use a thin wire to connect the two ends of the moment, how long should this thin line be?"

Gongsun Chang was stunned for a moment, and calculated slightly, "It should be five inches." ”

"What if one side is four inches long, and the other is six inches long?

Gongsun Chang frowned, and the Sanhao Daoist in the distance was also confused.

"It's about a little more than seven inches," Su Qi said casually, "Mr. Gongsun, I'll change the question, if this moment is a little broken, the two sides are not straight, but at sharp angles, and the length is still three or four inches each, how long will this line be?"

Gongsun Chang shook his head, "I only know that it is short, but I don't know the specific length." ”

"How to calculate this is called geometry. Su Qi glanced back at the mountains and forests, he had already drawn the formation here, he hooked his hand slightly, and the two spirit pens quickly flew up, landing on the mountain road away from the fire peak, and drew another part of the formation, "Mr. Gongsun, can you think of the use of this algorithm?"

Gongsun Chang pondered for a moment, and gradually came to his senses, "It's the angle and shape of the formation, you can rely on this algorithm to quickly estimate the angle and shape of a formation!"

Su Qi nodded, "The formation pattern was originally drawn on paper, and there is no need to consider the complex terrain problem, but in fact, the ground is not flat, if a stone suddenly appears in front of you, should a formation pattern go around or run over the stone? If it goes around, should it be drawn as an arc or several straight lines? How round is the arc? How long is the straight line? How to draw it to make the formation work perfectly? These can be estimated with geometry." ”。

Gongsun Chang was silent for a long time, "This method ...... It's peculiar. ”

"No, Mr. Gongsun, you actually draw formations like this, but you are relying on experience, these experiences come from your predecessors or masters, and also from your adult practice, when you draw formations, you will naturally associate the terrain in front of you with similar terrain in your past experience, so when young and inexperienced formation masters draw formations, the fit with the terrain is generally only five or sixty percent," Su Qi blinked," I've just turned this experience into a calculating method, and while I'm mostly estimating when drawing formations, it's far more accurate than others. ”
