Nie Fei, who returned to his courtyard, glanced at the cultivation room where Li Ruoyun was, the door was closed, and there was no trace of being opened, it was estimated that this girl would not be able to leave the customs for a long time.

Nie Fei entered his cultivation room and first took out the book "Air Explosion Technique", this exercise was only a little more than a hundred words, but in terms of the degree of wonder, it even surpassed Nie Fei's hegemonic body technique.

Sitting cross-legged, Nie Fei ran the true yuan according to the running route of the exercise, and within an hour, he practiced this explosive qi technique, tried to burn half of the true yuan in his body, and Nie Fei blasted out a punch burst fist technique.

"Bang bang bang!"

Four explosions sounded in a row in the cultivation room, and the power of the Burst Fist Technique was actually raised by a level! This secret technique is really awesome!

Nie Fei tried the rest of the martial arts one by one, and only after thoroughly finding out the maximum optimization effect of the Qi Explosion Technique did he stop the experiment.

Finding out the formation jade slip that the Nine Elders had given him, Nie Fei read the contents intently.

The introduction of the formation is recorded in the jade slip, no matter how complex all the formations are, they are inseparable from the core formation, and there are ten kinds of core formations, namely: ten square arrays, nine palace arrays, gossip arrays, seven star arrays, six arrays, five elements arrays, four elephant arrays, three clear arrays, two yi arrays, and one yuan array.

The difficulty of the ten squares is the least, and the difficulty of the one-yuan array is the largest, and the jade slip only records the detailed explanation of the ten squares, and there is no record of the other nine formations.

Each core formation can evolve into thousands of different formations, and these evolved formations can be roughly divided into: trapped formations, defensive formations, and offensive formations.

Among them, the trapped array can evolve into special formations such as phantom arrays and maze formations, and all formations can be superimposed and intertwined with each other to reach the point where there are arrays within the arrays and arrays outside the arrays......

This night, Nie Fei's mind was all immersed in understanding the formation, and when he finished reading all the information in the jade slip, the sky was already hazy and bright, Nie Fei had to sigh, the formation was really broad and profound!

Taking advantage of the fact that it was still early, Nie Fei came to the courtyard to practice for a while, familiarized himself with the Qi Explosion Technique he had just learned again, and then after breakfast, he went directly to the Ninth Elder to report.

Today's Nine Elders are wrapped in pale pink clothes, draped in white gauze, revealing a graceful neck and clearly visible collarbones, three thousand green silk tied up with a hairband, a butterfly hairpin on the head, a wisp of green silk hanging on the chest, thin powder, only add color!

The unique femininity of a mature woman was brought into full play by the Nine Elders at this moment, and Nie Fei couldn't help but feel a little faster in his heartbeat, and even when the Nine Elders explained to him the arrangement of the Ten Phalanxes, Nie Fei was a little in a trance.

Forcibly shaking off the cranky thoughts in his head, Nie Fei forced himself to concentrate and listen carefully, and after a while, he was immersed in the mystery of the formation.

"Well, did you understand what I said?" Elder Nine spoke for a long time and felt her mouth dry, so she picked up a cup of tea and put it to her mouth, her lips opened slightly, and then she took small sips.

"Well, I see." Nie Fei's gaze fell on the red lips of the Ninth Elder, and he couldn't help but swallow his saliva.

"What? Are you thirsty too? The teapot is on the table, go pour the tea yourself. Thinking that Nie Fei was also thirsty, the Nine Elders pointed to the teapot on the table and motioned for Nie Fei to do it himself.

Nie Fei's old face turned red, and he hurriedly used pouring tea to hide his embarrassment, grandma's! Since he had a relationship with Liu Yuechan, his concentration is getting worse day by day, Nie Fei doesn't know what went wrong, so he has to attribute all this to the sequelae of tasting the taste of forbidden fruit......

"Okay, that's all that's been said, now I'll teach you how to arrange the simplest ten squares." The Ninth Elder didn't think much about it, and then taught Nie Fei to arrange the formation, and Nie Fei also learned it seriously.

At noon, the Nine Elders had finished practicing the basic arrangement techniques of the Ten Phalanxes, and then asked Nie Fei to try to arrange a Ten Phalanxes by himself, Nie Fei rubbed his hands excitedly, and he could finally do it himself!

The Ten Phalanx had ten array eyes, and the Nine Elders used ten small order flags as array eyes to arrange a simple trapped array. Nie Fei's first attempt to set up the formation was naturally not very smooth, and he often had just arranged ten Ling Flags, and after a while, a large number of Ling Flags fell.

The Ninth Elder just smiled and said, "The formation pays attention to mental concentration, and there is no room for the slightest mistake, every time you arrange the array eye, your divine sense must fit perfectly with the Ling Qi." ”

Nie Fei tried it according to the method of the Nine Elders, and sure enough, it had some results, at least after arranging a formation, it could last for a few breaths for a short time, but this was obviously far from enough!

"Hehe, there is progress, but it's not enough, when you can successfully arrange this formation, we will start the next step of learning." The Nine Elders said with a smile.

"Master, don't worry, I will definitely succeed in arranging this formation." Nie Fei said firmly.

"Okay, you can explore on your own for a while, I'm a little tired as a teacher, go back to my room to rest for a while, and I'll come back to you when you have any questions." The Ninth Elder yawned and said.

"Okay, Master, go and rest." Nie Fei continued to fiddle with the ten order flags in his hand, and said without raising his head.

The Nine Elders bowed slightly, and then Shi Shiran left, leaving only Nie Fei alone in the hall on the first floor to practice arranging the formation alone.

Failed once, failed twice, failed three times......

After seven attempts to set up the formation, all of which ended in failure, Nie Fei stopped and turned to think about what went wrong.

The Ninth Elder said that when arranging the formation eye, it was necessary for one's divine sense and the order flag to achieve a perfect fit, and he had barely achieved this, but the formation still failed, why?

His gaze swept over the ten order flags again, Nie Fei's heart moved, and he poked out his divine sense and swept over each of them, no! There are some slight differences in the true elements carried on these ten order flags!

The array eye is the core of the formation, and the true element carried on each formation eye must be consistent, and there is no room for any difference!

After figuring this out, Nie Fei tried again, and finally arranged a ten-square formation, but it didn't take long for him to be happy, and this formation collapsed again.

After a look at the divine sense, Nie Fei discovered the reason, there was a difference in the true element carried by half of the ten order flags, although this difference was very small, but it still had an impact on the formation.

Grandma's! I don't believe I can't handle these few little flags! Nie Fei gritted his teeth and fiddled with these command flags again.

After failing a few more times, Nie Fei had to sigh, this Nima is too difficult, right? The true yuan attached to the ten order flags, if you want to reach unanimity, it is not possible to do it in a day or two!

No wonder the Ninth Elder left herself alone, it turned out that she had expected this result a long time ago, and she didn't want to waste time here with her!

Nie Fei's eyes rolled, since the true yuan is not easy to control, what will happen if I switch to soul power?

As soon as he thought of it, Nie Fei put away the true yuan, used his soul power to wrap the ten order flags instead, and then carefully planted all the order flags firmly on the ground in the order of the formation arrangement......
