"It seems that this Flame Sky Mountain, it is really not as simple as imagined, the underground space, you must take time to investigate!" Yi Yunfei kept walking around the room, the thoughts in his mind only turned, this huge palm print printed on the earth brought him too much shock, if it wasn't for the coincidence, maybe he would not find the clues until he cultivated the [Xuanling True Sutra] to the next realm, and the divine thoughts could completely cover the entire range of the Flame Sky Mountain.

The owner of this huge palm can't guess who it is, but he definitely won't slap it here for no reason, it must be something in this place that has aroused his anger before he makes a move. And the thing that can make such a master make a move will definitely not be small, and the person or sect that caused this matter will definitely not be simple.

However, after a short shock, Yi Yunfei also calmed down, the Fire Cloud Sect has been established here for hundreds of years, and now many disciples of the Yi Cloud Sect are disciples of the original Fire Cloud Sect, if they know something, they will not hide it from him. In other words, the appearance of this palm print, at least hundreds of years ago, or even longer, at least for the time being, will not pose any threat to Yi Yun Sect.

After cleaning up his mood, Yi Yunfei also began to think about how to set up the formation, and began to study the formation he wrote and drew on the paper, the formation obtained from the trial space was not suitable for forming a complete Sect Protector Great Array, after all, he had only studied the formation in the trial space for eight days.

Now he can only make some arrangements according to the terrain of each exit position, and then arrange some formation guards at each peak.

Yi Yunfei retreated for ten days near the earth fire under Tianfu Peak, and the stubborn old man Zhou Qingsong really regarded Yi Yunfei as a master, Yi Yunfei was indeed not used to it for a long time, and he was a little afraid of meeting this old man, but after getting used to it, it didn't matter, during this period of retreat, he also learned some refining methods by himself, taught Zhou Qingsong, and really took on the responsibility of being a master.

This old man is more than one hundred and thirty years old, and he has not married or had children, all his energy is focused on refining weapons, and he is very quick to accept this aspect of things, and he only needs Yi Yunfei to teach him once or twice at a time, and the old man will be able to get started. It can be regarded as helping Yi Yunfei a lot, otherwise, in just ten days, he would not be able to make so many array flags.

Formation, if it is a formation that does not involve spiritual power, it is just a large construction project. When it comes to the formation of spiritual power, you need to use things like array flags and array disks. The inscriptions required for the formation are engraved on these things, and then placed in a specific direction, and the aura and spiritual power are attracted to exert the power of the formation.

It was not easy to refine these things, and at the beginning, it took Yi Yunfei three days to refine a formation flag, and he was still exhausted. However, with Zhou Qingsong's help, one person is responsible for refining, and the other is responsible for inscription, and the speed is much faster.

The array flags refined in ten days could not fully meet the needs of the entire Yi Yun Sect, and Yi Yunfei's current cultivation was not willing to be able to arrange too large formations, but these array flags were enough to protect the more core areas of each peak.

During this time, although the peaks strengthened their guards, and the patrols of the two guards also changed their methods and strengthened their efforts, there was still a disciple who was missing, and even the body has not been found so far. Yi Yunfei could only refine a batch of array flags at the fastest speed to protect the important area, and then slowly figure it out.

When he was refining the array flag, everyone in Yi Yunzong went out in unison, and according to the drawings drawn by Yi Yunfei, many small formations were arranged around the sect, although the power was limited, but at least it could resist for a while.

Tianfu Peak, Yi Yunfei's body changed, the array flags in his hands were inserted one by one, several intermediate spirit stones were inlaid one by one, and with a gentle buzz, a transparent film of light appeared out of thin air, enveloping the top of the peak.

At Yi Yunfei's signal, several disciples tried to move towards the top of the mountain, but they were quickly bounced back by this light film. Then there was a weapon to slash towards the transparent light film, and the formation instantly exerted a huge power, and all the power of the slash bounced back, and several disciples didn't pay attention for a while, the weapon in their hands was bounced out, and their bodies couldn't stop retreating.

Seeing that the formation had such an effect, Yi Yunfei also nodded with satisfaction, and he personally experimented again, and under the full bombardment, the formation could not be broken through. Unless he encounters someone who is as proficient in formation as he cracks the formation flag, he will definitely not be able to enter the top of Tianfu Peak without a sound.

He hadn't thought of using the formation to completely resist the incoming enemy, just to guard against those flies and rats like spying, and he was very satisfied with such an effect.

He simply arranged all the formation flags, Tianfu, Tianji, Tiantong, Tianliang, Tianxiang, Seven Kills, and the important positions of the six peaks were all arranged by him This kind of formation, unless there is a special waist card made by him, otherwise he cannot enter and exit.

After some arrangement, Yi Yunfei retreated again, the purpose of this retreat was, on the one hand, to refine more talismans, so that the disciples could have a fighting strength when they encountered foreign enemies. On the other hand, after he obtained the [Origin of All Things], his understanding of the rune seal has also improved greatly, he used to only think that the fire rune and the thunder rune are the most effective rune seals, but now, he also has more ideas.

Not to mention that among the runes and seals that have appeared in this world, there are many different runes such as imprisonment, fire, thunder, wind, etc., and there are many small seals in Yi Yunfei's memory, which can appear as runes, such as "town", "guard", "wind", "fire", "thunder", "electricity" and other words, he feels that they can be made into runes. Moreover, no one has ever said that only one word can be written on the Fu Seal, but what if it is two words? In some novels he has read, the Fu Seal is described as almost omnipotent, such as "acceleration", "healing", "protection", and "stealth......

These thoughts have actually been lingering in his mind for a long time, but during this time, he is always in a relatively nervous state, and he has no heart to delve into these.

The study of formations in the trial space is indeed extremely useful, but the time is too long, if a new rune can be developed, it can be achieved immediately to improve the strength of the entire sect.

The talisman used in the news, Yi Yunfei only took one day to successfully experiment, it was very simple, it was the word "Ming". This word is a word, the cry of birds and beasts, called "Ming", Yi Yunfei's mind is running, tasting the meaning of this word, the strokes in his hand are non-stop, and the word "Ming" written by a small seal jumps on the paper.

After the talisman was activated, a blue light flashed, transforming into a small bird with wings spread and flying high, and the bird flew quickly, making a clear chirp, and the sound could spread throughout the entire sect. It is very useful as a tool for reporting.

There was nothing to keep secret about this talisman seal, and Yi Yunfei simply taught the method of making it to dozens of Qitang disciples who sensed their loyalty through the Zongyun card, and asked them to step up the production and assign at least one such talisman to each Yiyun Sect disciple. At the same time, it is also a test of the qualifications of these disciples in terms of Fu Seal, doing everything himself, Yi Yunfei is also lacking in skills, there is a Zongyun card that can test the loyalty of disciples, Yi Yunfei is ready to accept two or three more disciples in Fu Seal, but ordinary disciples refining Fu Seal, it is impossible to have the same full mind as Yi Yunfei, he also thought that if he really accepted disciples, he might have to teach them some exercises of [Xuanling Sutra].

After everything was arranged, Yi Yunfei also started his retreat, anyway, now the sect has sufficient resources, and the things such as rune paper are enough for him to consume, constantly experimenting with new runes and seals every day, and then practicing the [Xuanling Sutra] after the consumption of divine thoughts, and then practicing the [Xuanling Sutra] again, after ten days, the [Refining God] chapter of the [Xuanling Sutra] is running again, the feeling of pain is already undetectable, and his heart is full of joy, this exercise, it seems that a breakthrough is in sight.

However, in the past ten days, the study of the rune seal has not been too smooth, and he has a very big grasp of the rune seal of the single word, and has produced a rune seal such as [Wind Fu] [Town Fu], and the effect is also very intuitive. When the [Charm of Peace] is used, it will have a huge suppressive force.

This did not bring much joy, and the multi-character seal he had been experimenting with had not made any progress. This made him a little disappointed!
