Although the talisman is powerful, it is extremely difficult to refine, compared to ordinary spirit runes, it is a million times more difficult, as for those ordinary spirit runes, Mu Fei has also understood, those things are inked with the essence blood of ghosts and beasts, and strange runes are drawn, and the power of the spirit runes can be seen according to the level of the ghost beasts used.

If the rune used is drawn by the blood of a first-level ghost beast, it is naturally a first-level spirit rune, and so on.

"With so many spirit runes, it shouldn't be a problem for this Tenglong Dabi to enter the top ten, and when the Tenglong Secret Realm is opened, I will use the exercises of the Five Elements Sect in the Tenglong Secret Realm, and it will be fine. Mu Fei thought in his heart, he put away the talisman, and the two storage bags were rummaged through by him, and in Meng Fei's storage bag, except for the soul reading chapter of the "Ten Thousand Arrays Treasure Book" and the black sword rune and the ghost spirit stone, there was nothing valuable, but that Shui Jie was worth a lot of money, and there were three ghost soldiers alone, although the black arrows and golden light mirrors could not be used for the time being, but the nine-section whip could still be used, and the other two dozen spirit runes could improve his strength in a short period of time, which was much faster than cultivating the exercises, and now what he lacked the most was time.

"In the next month, I will ponder the two exercises of the "Ten Thousand Arrays Treasure Book" and the "Soul Devouring Sword Decision", although I may not be able to practice perfectly, but it should not be a problem to fight the enemy. Mu Fei silently made plans for the next month, this is the Jiyin Mountain Range, where ghosts and beasts are rampant, which is suitable for him to practice.

When Mu Fei thought of this, he took back all the ghost spirit crystals that arranged the formation, withdrew the formation, and left the valley.

The Yin Mountains stretch for hundreds of kilometers, extremely huge, among which there are countless ghosts and beasts, and produce a kind of Yin grass, called Yin Yin Grass, this Yin grass is the basic material for making runes, in the production of spirit runes, the main focus is on rune paper and rune ink, paper determines how much energy a blank rune can carry, determines how much power the rune can play, and rune ink is to provide energy, both are indispensable.

Therefore, in the Yin Mountain Range, there are many monks who come for this, of course, this mountain range is so huge, it is impossible to have only this kind of Yin grass, and there will be all kinds of precious materials containing ghost aura. Therefore, this mountain range is definitely not inaccessible, and it can even be said that there are often groups of monks who come to this mountain range in groups to look for opportunities, and those who get the Yin Grass and Yin Fruit can naturally increase their strength, but there are also those who die in the mouths of ghosts and beasts, and even those who die in the hands of their companions.

Mu Fei now has to find a hidden place to master the two sets of exercises of the Soul Thought Chapter and the Soul Devouring Knife Decision, and then practice with the ghosts and beasts in this mountain range.

Familiarize yourself with these two sets of exercises as soon as possible, and I'm afraid you will have to use these two sets of exercises as the main means in the future, after all, what he knows is the methods of the Ten Thousand Elements Sect and the Five Elements Sect, and if he uses them, he will inevitably be suspicious, especially if he can't use them in front of the people of the Five Elements Sect and the Ten Thousand Elements Sect.

Mu Fei's body flickered, and the escape method on "Wood Spirit Decision" was used by him to the fullest, but he saw that his whole body flashed with blue light, and the whole person sometimes appeared, sometimes disappeared, and it was only a few tens of breaths of effort, and he disappeared into this forest.

......

Ten days later, in a swamp with continuous water, there was a roar, accompanied by an angry cow roar.

"Soul Eater Sword!"

A cold drink sounded here, followed by an astonishing outbreak of evil qi, but in the swamp, a young man in sackcloth was holding a blood-colored long knife, and the evil qi on the long knife spread, forming a knife-like phantom, and a terrifying coercion surged from this knife-like evil qi.

This person is naturally Mu Fei who has been in retreat for ten days, and in these ten days, Mu Fei has devoted himself to studying the Soul Thoughts Chapter and the Soul Devouring Knife Duel, and has gained a lot, especially the Soul Devouring Knife Duel, which has been able to use the evil qi on this blood knife to exert the five-layer power of the knife duel, don't underestimate these five layers of power, even ordinary ghost soldier realm monks, may not be able to resist the evil qi Daogang produced by this sword duel.

However, the soul thought described in the soul thought chapter, Mu Fei has not been able to understand the essentials, even with his self-awakening talent, he can't understand the secret of this soul thought.

At this time, opposite Mu Fei, there is a huge cow-shaped ghost beast standing, this cow is the famous ghost beast of the Jiyin Mountain Range, the crazy cow is huge, there are two floors of small buildings, the green skin is visible, there is a faint blue light, obviously there is a yin wrap, a pair of black horns on the head are like a crescent moon, roaring to the sky, and the sharp horns are flashing with a chilling cold light.

At this time, Mu Fei's soul devouring knife had already condensed and formed, and in the roar, a knife slashed towards the mad divine cow, the sword was like a dragon, and the blood flashed, thinking about this beast and slashing away.

The power of this knife is that ordinary ghost pawn realms dare not resist.

However, the mad cow on the opposite side mooed, and the front hooves slammed on the ground, and suddenly the muddy water splashed, and the ground was visibly sunk into a big pit, but the beast still rushed wildly, and it didn't even dodge, it directly touched each other with its horns!

Bang!

There was a loud bang, but he saw that the blue light flashed all over the mad cow, and the knife left a faint white mark on the beast's body, that's all, Mu Fei's face changed slightly, and his body flashed wildly, dodging the collision of the mad cow.

"It's worthy of being a third-level ghost beast that is good at defense, it's really powerful, just this skin, with my maximum attack power now, I can't break it, fortunately, the mad god cow has a speed disadvantage, otherwise I really wouldn't dare to come here to practice with this beast." Mu Fei couldn't help but sigh in his heart, his eyes flashed, his body kept dodging, and at the same time, the blood knife in his hand was raised again, and the ghost spiritual power of his body was mobilized, urging the blood knife, and the evil qi rushed out again.

Boom! Boom!

Slashing again and again, Mu Fei's knife skills became more and more proficient, and the power became more and more powerful, but he still couldn't break through the defense of the mad divine cow.

Mu Fei dodged while spinning in his mind: "This Soul Devouring Knife Determination Technique is not exquisite, but this evil qi is amazingly powerful, but if it is against the enemy, it will not allow me to steadily enter the top ten of the Dragon Competition, when Jian Yuxi used this knife to fight, but the power is amazing, there must be some tricks I have not discovered." ”

When Mu Fei fought with Jian Yuxi in the formation, Jian Yuxi used the Soul Devouring Knife to fight with outrageous power, and even split the formation he arranged for a while, although Jian Yuxi was a master at the level of a ghost general at that time, and he could already attack with a ghost, but Mu Fei felt that the object was just a skill, as long as there was enough ghost spiritual power, his current realm might not be able to resist things, and there must be other tricks in this, the Soul Eater Knife Decision, obviously not so simple.

Mu Fei was thinking about it, the crazy divine cow on the ground had already been provoked by Mu Fei to go crazy, the four hooves ran wildly, the blue light around his body soared, the whole body was a few feet high, and the green skin on his body also became bloody, and the pair of pitch-black horns also turned dark red at this time.

"Madness!"

Mu Fei's face changed, and he was shocked, the name of this mad god cow has a crazy word in it, it is because this beast has a talent, madness, this talent will be stimulated when this beast is extremely angry, once such a state is activated, the mad god cow will become extremely manic, this is not enough, more importantly, this state of the mad god cow, speed, strength, defense will increase a lot!

"I couldn't hurt this beast just now, but now that its strength has increased dramatically after it has gone berserk, I can't kill this beast anymore, and it is really not wise to choose to use this beast to cultivate the Soul Devouring Sword. Mu Fei smiled bitterly in his heart, he already had a retreat in his heart, his body flashed slightly, his whole body flashed with blue light, and he suddenly disappeared into the air, and when he reappeared, he was dozens of zhang away, and his position also changed.

After the mad god cow turned crazy, it was even more irrational, although the speed increased, but it was still not as good as Lan Li, so Mu Fei easily escaped the impact of the mad god cow.

After Mu Fei dodged the attack of this mad sacred cow, his body moved, and he knew that he could not kill this beast, so he had to leave this place. But at this moment, in the jungle not far away, there was a laugh.

"Brother don't panic, I'll help you below. As the words fell, I saw that in the jungle, an astonishing ghostly aura came from the pressure, and a bloody knife tore through the bushes, drawing a phantom shadow, and slammed into the back of the mad sacred cow.

Boom!

Hearing a muffled sound, the bloody knife suddenly slashed at the back of the beast, and the mad divine cow roared in pain, turned around suddenly, his eyes were scarlet, and he looked at the woods manically.

When Mu Fei saw this scene, he was shocked, but he saw that the back of the mad divine cow was actually split by the knife, revealing large bones, and blood flowed out.

How strong is the defense of this mad divine cow, Mu Fei knows best, just now this beast has not gone crazy, but his soul devouring knife will not be able to cause the slightest damage to this beast, and now under the madness of this beast, it is impossible for him to leave a white mark on this beast, but that blood knife can actually tear the skin and flesh of the mad divine cow in a mad state, what kind of attack power is this?

"This is definitely a ghost general-level attack power!"

Mu Fei instantly made such an evaluation in his heart, and at the same time, he couldn't help but think in his heart: "Could it be that the person in the bushes is a monk at the level of a ghost general? Why does this person help him? And why is he hiding in the bushes?"

Mu Fei was thinking about it, a figure in the bushes was like a cheetah, flying out quickly, and at the same time, this person beckoned, and the blood knife flew back, and the person held the blood knife and slashed towards the mad god cow again!

Mu Fei's pupils shrank suddenly, and with that beckon, the blood knife flew back in an instant, which was clearly the art of the imperial object!

This person is a ghost general-level master!

Mu Fei was sure in his heart, and then looked at the person, but saw that the person's hair was messy, dressed in animal skin clothes, full of muscles, and the blocks were distinct, containing explosive power, this person turned his back to Mu Fei at the moment, his arms were raised, and the blood knife was regarded by him as an iron pillar at this moment, raised high, and he slashed down with a violent attitude!
