"Speaking of which, the price is still too expensive, most of those who spend money to help design the simplified spirit array are the sons of families who have just awakened and are about to go to the border, they can afford and are willing to pay this money, and they will be honed on the battlefield for several years, as long as they can cultivate an earl-level powerhouse in the future, they will earn back the money for several generations to obtain the simplified spirit array."

Ning Xu ate the bread in his hand in two bites, and said with some sighs.

"After all, not everyone can be like my brother, since he graduated and went to the battlefield, he brought a professional formation mage, the four ways of the Dan Weapon Rune Array are extremely difficult, and it is very difficult for people to learn, you must know that at that time, Ning Yu was a second-grade spirit array master, and he was still a baron-level scholar, compared with ordinary professionals who only knew how to simplify the spirit array, it was much stronger."

"Well, and do you know that the so-called design of the simplified spirit array is not to teach you how to arrange it little by little like the conventional teaching, nor is it to give you a scroll of array diagrams to follow the map, but the spirit array master uses his own formation attainments to arrange a first-grade spirit array, condensing a brand, similar to inheritance, after being absorbed, the absorber will naturally learn the simplified spirit array recorded in it."

Originally, she was only slightly concerned about this matter, and she was a little stunned, in her opinion, Ning Xu could at most draw a formation map for her by rote memorization, after all, what is the difference between taking the formation chart to the exam and blatantly cheating? Even if you learn, you will have a little peace of mind when you learn, and it won't help at all, who knows......

Looking at the stunned appearance of the dark night, Ning Xu couldn't help but chuckle to himself, if he hadn't seen the dark night's thoughts, would he be guilty of explaining this thing? That must be impossible, tsk tsk, it's not to please the beauty, compared to other girls, only the dark night, can make him look at it.

So, Ning Xu spread his hands: "It's normal to cultivate this thing, it's not scientific, it's not logical, if this thing is scientific, there will be something wrong with it, just when the catastrophe happened, someone tried to use the electricity system spell to provide a ceremony, and after the voltage change, he supplied power to the city and ended up splitting the people next to him half to death." ”

"However, you see that I don't have spiritual power now, and I have to rely on the chess formation to find another way, and it is far away to break through to a first-grade spirit array master again without spiritual power, so as long as your spiritual array attainments are not bad, then I can guide on the side, and you can draw the spirit array by yourself." Saying this, Ning Xu couldn't help but spread his hands, with a wry smile on his face.

"Seriously, as long as you can ensure the smooth output of spiritual power, because I have enough attainments now, but because I don't have spiritual power, I have to use spirit stones for energy, and I have to transform the formation on the basis of the existing spiritual array, which is still difficult to say."

"I'll do my best, when I drew the spiritual array in school before, the spiritual power control was acceptable, that is, the formation diagram that I had memorized many times, there was no mistake when I drew it with an ordinary pen, and once I used spiritual power to draw it, I would forget it."

Styx tilted his head, his face showed a hint of distress, Ning Xu already knew it in his heart when he heard it, because to practice drawing the spirit array, it was necessary to use a special spirit weapon array pen, as well as a special paper made of heavenly and earthly treasures, because only this material could withstand the effect of the formation, and to get out of the spirit paper cloth array, at least one product had to be reached, and these two things were quite expensive, and they were not something ordinary people could bear.

In the city, it is also forbidden to arrange offensive formations at will, of course, if it is for defense or hunting demon seeds, it is a different matter.

So in general. Civilian students have practiced countless times with ordinary paper and pencils, and only after ensuring that they are familiar with them will they buy a few pieces of spirit paper and rent spirit pens to practice.

So Ning Xu rummaged through things and explained with a smile: "This method is only suitable for some people, because this thing is not scientific after all, if you don't understand it, if you don't really understand it, if you don't really understand the spirit array, you will naturally forget it if you want to arrange the formation, just like enlightenment, only if you understand it is your own, otherwise if you let people arrange the spirit array while looking at the formation diagram, wouldn't it be a cultivator who is a spirit array master?" Simplifying the spirit array is the simplest in the spirit array, and some people have talent for certain formations, and they can also learn some in the process of rote memorization, so they can naturally lay them out. ”

"Well, that's it." Ning Xu said and spoke, his hand moved, and his face showed a little joy, only to see that he was holding an object that looked like a pencil in his left hand, but the tip of the thing was pale silver, and there was a little light black liquid in the pen, which shook with the shaking of Ning Xu's hand, and his right hand was holding a stack of paper like silver foil, on the paper, there was a faint spiritual light dangling.

"Well, my brother used to buy me the spirit paper and spirit pen, but I haven't used it much since then, after all, I've been trying to get out of this thing after that, and so on." Ning Xu seemed to suddenly remember something. "Maybe you can inject spiritual power into my body, and I will try to use your spiritual power to draw a spiritual array, so it doesn't need to be so troublesome."

"As long as I restrain the Black Xuanlong Qi, I remember that last time, your spiritual power didn't have any conflict with me in my body, maybe I can really try to manipulate your spiritual power."

Hearing Ning Xu's words, Styx raised her eyebrows, but she didn't object, after all, after Ning Xu saved her and lost her spiritual power, she treated him a lot, after all, there was a little guilt, if he could borrow the frost spiritual power, it would be a good thing, and as the owner, she could vaguely feel that her spiritual power seemed to have a great affinity for Ning Xu, although the spiritual power was not conscious, but she had always felt this way.

Of course, if other people hear this conversation between the two, they will have to laugh at it, can there be such a thing as spiritual power that can be used interchangeably? At most, it is between the elders and juniors of the family, the power is of the same origin as each other, and they can use the power of the elders to release powerful killing moves that they can't use before, and if others want to forcibly use the power of others, it is easy to cause a backlash, which is often mentioned by teachers in school.

It's just that for some reason, when these two people discussed this matter, they didn't seem to know about it at all, just as normal, and the whole thing seemed to have a force in control.

As soon as the words fell, Styx reached out and took the initiative to hold Ning Xu, and as soon as her heart moved, a stream of spiritual power poured out of the dantian, and poured into Ning Xu's body along the meridians of her arm.

Ning Xu's eyes were tightly closed, and when that spiritual power had just entered his body, he wrapped it up with a soul power, pushing it towards his other hand.
