Whether it is pi or ninety-nine multiplication, it is the crystallization of the wisdom of mathematics that has been passed down for a long time in the ancient country of the Celestial Empire in the world where Lu Qing is located.

However, in this ancient Xianxia game world similar to the Celestial Empire, the people here have not studied this way.

The formation is naturally mysterious and profound, but in this world where all cultivators have a great heart, there is only a lack of those true explorers.

There were only a handful of formation masters, and no one had explored the deeper mysteries of mathematics.

No one would have thought that this idea, which no one had ever explored, would be seen through by Lu Qing, a traverser.

The memory in his mind was still clear, and when Lu Qing carefully pondered the formation, it was as if he had obtained a pair of heavenly eyes, and he could always find the easiest way to understand it, simplifying the originally complicated things to the extreme.

The formation that was complicated and obscure for others fell into his hands, but it became extremely simple.

However, at this time, no one, including Ao Qing, believed that Lu Qing was the "wizard" of the eternal formation.

Slowly opening his eyes, Lu Qing broke away from his self-realization, and even he didn't know how long he had been pondering.

"There are two days left." Ao Worm opened his mouth to remind.

"That's a day?" Lu Qing was a little surprised, his state just now was like suddenly becoming interested in something, immersed in it only felt that time flew by, but he did not feel bored.

"So what's wrong with you?" Ao Worm was skeptical.

"I think I can start trying to set it up!" A smile appeared on Lu Qing's face.

"Then be careful." Ao Zhi said lightly.

After all, if the formation fails, it is possible that the formation materials will cause an explosion or other accidents.

You must know how many formations were accidentally developed from failure, and how many unlucky formation mages were injured or even killed because of rash formations.

"Are you so unconfident in me?" Lu Qing smiled bitterly.

"I'm not unconfident in you, I'm very confident in my common sense!" Ao Zhi replied.

Are you kidding? If even Lu Qing, who had learned the formation for a year, learned it in just one day, then was he a fool? Are all the formation mages in the world stupid?

This kind of thing, no matter how you think about it, can't happen in reality.

"Then you're probably going to be disappointed! I don't say that I am nine out of ten sure, at least eighty percent sure that the layout will be successful! Lu Qing said with a smile.

"Then you're really bragging, don't make drafts~" Ao Chi's tone was a little yin and yang.

"Don't be in a hurry to taunt me, otherwise I'll be slapped in the face, how uncomfortable it is!" Lu Qing didn't care about Ao Qing's taunts, because the more he taunted now, the more painful his face would be.

"We'll have to wait and see." Ao Fei still didn't believe it.

No longer fighting with Ao Qing, Lu Qing caged out a bunch of formation materials from the side, and his movements were as skilled as a senior formation mage.

His action made those who were observing him look up at him.

"There are also decent ones, and the amount of materials used in the array can be grasped at one time." Ao Cede muttered to herself.

"He seems to have the talent of a formation mage." Yu Qianying smiled lightly.

"Hmph, pretend!" Hu Mi was not nervous, just a little surprised.

The composition of the formation is basically divided into three major elements, the formation base, the formation eye and the formation body.

Among them, the formation base is the most important, which can be said to be the core of the formation and a necessary ingredient among the three major elements.

Some real formation masters can ignore the formation eye and formation body by injecting heaven and earth aura, and only use the formation base to draw the formation, and it also has a certain effect.

One of the most famous is the legendary "Eight Gate Formation".

An overall formation can have no formation eyes and no formations, but it is common sense to definitely have a formation base.

Second only to the existence of the formation base, it is the formation, although some formations do belong to the formation base to form the whole, but the truly powerful formation is absolutely indispensable to the composition of the formation.

The final array is relatively unimportant, but it is the icing on the cake.

It's like the finishing touch in a painting, a mediocre formation, if the formation eye point is good, it can even rise a whole level.

However, the existence of the formation eye is actually a weakness in the formation, because the formation with the formation eye is generally broken, and the formation is basically destroyed as a whole.

And those real formation masters can definitely hide the formation eye to a level that you can't find at all.

What Lu Qing has to do now is to first draw out the formation base in the Xuanshu Killing Array, which is his first step and the most difficult step in the Xuanshu Killing Array.

Why can the Xuanshu Killing Array use the least and cheapest materials to create a powerful killing array? The core of this formation lies in the drawing of the base of this formation.

The superb painting array skills can make this power to the extreme.

And if you are not proficient in learning, you may only need a little flaw to draw a waste formation, which is also a very ordinary thing.

For example, Ao Fede, he said that when he was learning the Xuanshu Killing Array, he drew not a thousand but eight hundred waste formations.

At this time, under the gaze of the three eyes, Lu Qing took out a purple sand pot filled with Xuansha powder from the pile of formation materials.

Xuansha powder is a formation material mixed from the grinding of bassarite and spirit stone, and its ability to conduct spiritual energy is very powerful, and it is indispensable for most formation drawing formation bases.

Holding the Xuansha powder pot in his hand, Lu Qing took a deep breath and began to draw his formation base.

The wrist is tilted, the movement is smooth, and the sand powder is inclined down the spout, and the quantity is very uniform.

"What is he doing?" Looking at Lu Qing's movements, the three people who were paying attention to him had a sense of doubt at the same time.

Because Lu Qing was completely messing around, it seemed that he was just trying his feelings.

"It's thunder and rain!" Hu Mi breathed a sigh of relief, she saw Lu Qing's confident appearance just now, and to be honest, she was indeed a little panicked, but now it seems that she should have thought too much.

"Well, that's what it feels like." At this time, after trying the feel, Lu Qing made another behavior that surprised everyone.

Lu Qing took out a long bamboo pole from the storage bag, and then hung up the purple sand pot with the sand powder, and no one understood what he was going to do for a while.

And the next moment, Lu Qing stood in place by himself, and then spun with a bamboo pole in his hand.

In a few moments, he drew a very regular circle with himself as the center of the circle.

"This?!" Ao Chi exclaimed, completely unexpectedly that such a scene would happen.

"It's amazing, I can even think of this method to draw a circular formation base, I don't think anyone can draw a more round shape than him." Yu Qianying couldn't help but admire.

"And this kind of operation?!" His eyes widened, Hu Mi's little head couldn't have imagined that the circle could still be drawn in this way, and it was so perfect......
