Mu Fei put away the storage bag, and he turned around, and at this time the valley had been destroyed and in a mess.

"Such a big movement must have alarmed the people in this neighborhood, and they must get out of here as soon as possible. Mu Fei's eyes flashed, his body moved, turned into a gust of wind, and left this place.

Half a day later, Mu Fei appeared on a vast grassland, the grassland here was verdant and green, no longer like the gray in the Broken Soul Mountain Range.

Mu Fei flipped his wrist, and a piece of jade slip appeared in his hand, and his ghost spiritual power entered the jade slip, and suddenly the light in the jade slip flashed, and a huge map flashed.

"This place is called the Yin Grassland, and it is a necessary place to go to the land of doom. There are countless ghost beasts here, the most common are the Yin Wolf, the Crazy Divine Cow, the Silver Horn Golden Sheep, the Evil Hook Eagle and other four ghost beasts, all of which are second-level ghost beasts. Mu Fei groaned and read the information marked in the corner of the map, and had a general understanding of this Yin Prairie in his heart.

This map was found by Mu Fei from the storage bag of the Ghost Sword Sect disciple named Meng Yunran, and it recorded the detailed topography of millions of kilometers around this Tenglong City, but it was cheaper for Mu Fei.

Mu Fei looked at it, but saw that this grassland was very vast, with abundant grass and trees, as far as the eye could see, and occasionally there were undulating slopes, but they were not tall.

The most important thing is that in the map of the mountain, not far from here, there will be a high mountain, called the Yin Mountain, which is the only huge mountain range on this grassland, and the ghosts and beasts such as the Yin wolf and the crazy sacred cow are running out of this mountain range.

Mu Fei thought for a while, and secretly thought to himself: "That mountain range is extremely dangerous and very vast, but it is a good place to hide, and the Tenglong Dabi will be held next month, I have now broken through to the realm of ghosts, but I can occupy a place in the Tenglong Dabi, but if you want to enter the top ten, you can't use the exercises of the Five Elements Sect, it seems necessary to study the "Soul Devouring Sword Decision" Already, although it is impossible to reach the realm of imperial objects, it should be enough to manipulate the evil qi on the blood knife, and use the means of the paladin, even if it is recognized by the people of the Five Elements Sect, they will not dare to do anything to me. ”

Thinking of this, Mu Fei glanced at the map again, figured out the general direction, put away the jade slip, moved his body, and flew towards the Jiyin Mountain Range marked on the map.

Flying only half a day, Mu Fei saw a sharp mountain emerging from the horizon, as the flight approached, Mu Fei gradually saw the whole picture of the mountain, this mountain range is continuous, starting from thousands of miles away, the ground is no longer grass hurried, but some low bushes, the closer to the mountain range, the more tall trees, and at the top of the mountain range, you can see a group of gray birds swimming in the air, these birds have a unified characteristic, their beaks are extremely slender, some are even longer than their own bodies, the slightly curved beak edge, shining in the sun with a cold light, it looks sharp and abnormal。

Mu Fei thought to himself, this can't be the evil hook eagle, does it look so vicious.

As Mu Fei flew for a period of time, the mountain range appeared to be bigger and bigger, Mu Fei's figure appeared smaller and smaller, and when Mu Fei approached this mountain range, he could no longer see the top of this mountain range, since the mountainside, it was shrouded in clouds and mist, making this mountain unspeakably mysterious.

Mu Fei stopped flying, landed on the ground, flying in this dangerous area, it is obviously unwise, maybe he will be attacked by the evil hook eagle in the air, Mu Fei walked to the dense forest like this, the mountain road under his feet is rugged, but it is not a problem for Mu Fei, he performed the escape method in the "Wood Spirit Decision", and suddenly the blue light flashed all over his body, and the speed suddenly surged.

As soon as Mu Fei walked into this valley, he immediately felt that the yin qi here was extremely heavy, and it was a little damp, and the birds and beasts around him were crying, but there was a feeling of vitality.

Mu Fei wandered around for a long time, and finally found a mountain wall that looked very hidden, he looked around, and did not find that there were ghost beasts infested, and there was no water source here, no one should come, but for the sake of prudence, Mu Fei still laid out three thousand illusion realm formations, civil engineering formations, lightning guidance formations, frost gate formations and other basic formations on a mountain road that must pass through this mountain wall, although the power is not great, but it is enough to block the monks of the second-level ghost beasts or ghost pawn realm.

Last time, it was because of the benevolence of a woman, but he just laid a three-thousand-illusion realm, and he was taken advantage of by Meng Yunran and Shui Jie, who easily broke the formation, how could Mu Fei, who had suffered a loss, make such a low-level mistake. Therefore, he laid out several major formations in a row.

Anyway, since he killed that paladin Jian Yuxi, he has become a lot richer in his hands, and it is more than enough to arrange these basic formations.

After doing all this, Mu Fei dug a hole in the mountain wall, and after a simple arrangement, he took out his trophies, the storage bags of Shui Jie and Meng Yunran.

Mu Fei first took Meng Yunran's storage bag, and then urged the ghost spirit power, and suddenly the storage bag flashed, and a storage bag about the size of a room appeared in Mu Fei's mind, Mu Fei looked at the storage bag space, but saw thousands of ghost spirit crystals piled up in the corner, this scene made the corners of Mu Fei's mouth smile, no matter whether there were other things in the storage bag, just so many ghost spirit crystals were enough to make up for the treasures used to kill Meng Yunran.

Of course, the ghost soldier stone house was a loss that made Mu Fei's heart ache, and no matter how many ghost spirit crystals there were, there was no way to make up for it.

The preciousness of ghost soldiers, since Meng Yunran went to Tenglong City, he has already understood, although there are also ghost soldiers in those weapon shops, but they are all treasures of the town store, and they are generally not sold, and the ghost soldiers sold in the auction building are all tens of thousands of third-level ghost spirit stones can be bought, tens of thousands of third-level ghost spirit stones, which makes Mu Fei dare not think about it.

Mu Fei looked at the pile of ghost spirit crystals, and looked to the side again, there was a white jade box there, Mu Fei's heart moved, this kind of texture of the box, generally store more precious items, I don't know what is in it, Mu Fei's eyes flashed, and suddenly the jade box appeared in his hand, he looked at the box carefully.

This jade box is about a foot long and half a foot wide, the whole body is crystal clear, and there are faint formation lines engraved on it, Mu Fei gently stroked this jade box, and whispered to himself: "There is actually a seal? It seems that the things in it are very important." ”

Mu Fei condensed and carefully observed this sealing formation, this kind of formation he had never seen, and it was never mentioned in the "Initial Solution of the Formation", but with Mu Fei's understanding of the formation, he vaguely felt that this was a sealing formation.

"This formation is peculiar, I have to think about it. Mu Fei immediately became interested, for the formation, he was more interested than cultivation.

He gently rubbed the lines on the jade box, felt the texture of the formation, and felt the rules little by little.

The way of the formation relies on perception and deduction, followed by items such as ghost spirit crystals and array materials.

It can be said that the formation focuses on the concept and calculation, and some large arrays, which contain the principles of heaven and earth, have been arranged by some sects and used to improve the strength of disciples.

The purpose and reason of this sealing formation are also very simple, that is, to use the perception of heaven and earth by the person who arranges the formation to cut off the communication between a certain object and the heaven and the earth, so that there is a kind of rule left by the person who arranges the formation around the sealed object, this rule is not to say that it is the same as the rules of heaven and earth, but the formation mage makes some slight changes according to the rules of heaven and earth, so that the sealed thing is rejected by heaven and earth, and achieves the effect of isolation from space or time.

Some of the more powerful seals even contain changes in the five elements, gradually assimilating the sealed things into the rules of heaven and earth, thus completely destroying the sealed things.

Of course, Mu Fei naturally didn't know this, he was now in contact with the sealing formation for the first time, and at this time, in his careful understanding, he actually had some understanding, the sealing formation on this jade box would have a strange fluctuation, which could exclude the surrounding space, so that the jade box existed in an independent space like a storage space, so that the items in the jade box would also be preserved permanently.

The truth is a truth, but this is different from the Sumeru formation depicted on the storage bag, which is a kind of perception of the rules, but it is not something that Mu Fei can understand at this time.

However, Mu Fei could know how the formation on this jade box worked, which was enough for him to open this jade box.

Mu Fei picked up the jade box in his left hand, pointed out with the index finger of his right hand, and a body of ghost spiritual power quickly condensed at his fingertips, and in a moment, a needle tip condensed by ghost spiritual power protruded from Mu Fei's fingertips.

Mu Fei saw the formation pattern on the jade box, his finger lightly clicked up, and suddenly a strange fluctuation appeared on his fingertips, this fluctuation was similar to the fluctuation of the sealing formation on the jade box, Mu Fei's fingers did not stop, his fingertips rotated, and gradually drew a formation pattern similar to the sealing formation in the blank space of the jade box, this formation pattern is not complicated, but it is gradually drawn to the middle of the formation along the periphery of the original formation, but in less than dozens of breaths, Mu Fei is already sweating profusely, and the ghost spiritual power in his body is consumed only thirty percent!

"No, you have to work hard, otherwise it is very likely that the cracking will fail, and this jade box will be destroyed in the formation!" Mu Fei secretly gritted his teeth, if the formation failed, it would inevitably cause the formation to backlash, and when the time came, he could dodge it, but this jade box would inevitably be shattered, and the items in it would inevitably be damaged, which was not what Mu Fei wanted.

Mu Fei used the ghost spiritual power of his whole body, his fingers instantly accelerated, and his eyes were concentrated in the formation patterns like never before! The needle tips condensed by the ghost spiritual power on his fingertips became more and more dim, and the formation patterns on the jade box became more and more complicated.

Just when Mu Fei was about to lose his support, he suddenly snorted softly, and suddenly his hand speed surged again, and suddenly the formation on the jade box buzzed for a while, and then Mu Fei collapsed and lay on the wall, and the jade box in his hand also fell to the ground with a bang.

Mu Fei squinted, and suddenly his eyes widened, but he saw that the lid of the jade box had fallen, revealing the things inside!

It turned out to be a thin book!

"What is this?" Mu Fei was curious in his heart, the thing sealed in the jade box was actually a book, what was this book?
