The spiritual power of the Absolute Feather Dungeon is dense, and a large number of Bodhi Spirit Fruits have grown, of course, it is impossible that there is nothing to protect these Bodhi Spirit Fruits. This is a kind of rule between heaven and earth, where there are strange treasures, there must always be creatures that protect the strange treasures. In most cases, they are demon beasts, but this Peerless Dungeon that is isolated from the outside world has become these souls with quite a lot of combat power.

People in the mortal realm call them ghosts, but in the cultivation realm, they are more often called demon souls.

The demon soul is a monk or demon beast whose original state of mind cultivation is not low, and after the fall, due to some special circumstances, the soul has not dissipated and remains between heaven and earth. If this demon soul originally belonged to the soul of a demon beast, the cultivators in the cultivation realm were more inclined to call it a beast soul.

Generally speaking, even if a monk was originally a master at the peak of the Earth Yuan Realm, after becoming a demon soul, he often didn't have too strong strength. But if there are some spaces with heavier yin qi, the spiritual power of the surrounding heaven and earth is also relatively dense. These demons will gradually grow into equally difficult existences.

The vast majority of the demon souls in the Jue Feather Palace will be scattered every eight hundred years. The dispersal of demon souls does not mean that they have completely disappeared, and after a while, these remnant souls will gather again. Of course, because the soul power was exhausted, this demon soul could only start cultivating again from scratch.

Demon souls can also be cultivated, and in fact, the cultivation realm is not without those demon souls who are strong enough to walk in the direct sunlight. But whether the demon soul can grow or not is limited by too many factors. The demon soul that can become a strong first-level existence among the demon souls is much lower than the proportion of masters among human monks. In addition, the base number of demon souls is not large, and the known strong demon souls in the cultivation realm can indeed be called outrageous.

The spiritual power in the Absolute Feather Dungeon is dense, and every eight hundred years is enough for the demon souls that were scattered before to grow to the level of the first and second heavens of the Earth Yuan Realm again. There are also quite a few demon souls at the Triple Heaven level in the Earth Yuan Realm, but more of them are those demon souls who were lucky enough to escape and ascend to heaven when the Absolute Feather Dungeon was opened last time, and they only reached the height after cultivating for five hundred years.

In the previous passage, Lin Feng and the others saw three traces of battle. Those three places must also be the traces of the battle caused by the battle between the master and the demon soul who flew over before.

This time, Lin Feng and the others directly encountered the demon soul. That proves that at least in this passage, Lin Feng and they have come to the forefront. Before Lin Feng and them, no one had passed through this passage for the opening of the Absolute Feather Underground Palace.

The demon soul was still wandering in front, but Lin Feng and the others stopped.

"What should I do?"

Lin Feng looked at everyone, and finally made a decision: "There are too many passages in the Absolute Feather Underground Palace, and it is impossible to confirm where they have gone. We're going back from this passage now, and there will definitely be other forks in the road in a while, and the chances of chasing them down are slim to none. Now that we have encountered the Bodhi Spirit Fruit, we should still take it. It's really not good, so you can only launch a sneak attack on the pursuit of life after the Absolute Feather Underground Palace. ”

Now that such a decision has been made, Lin Feng and the others no longer hesitate. Ji Sihan put the Lion Lion King at the forefront, and Lin Feng and the others began to launch an offensive against the tiger demon soul.

Lin Feng had not faced an opponent like a demon soul before, but Lin Feng was still clear about the taboos of a demon soul opponent. Dealing with demon beasts like demon souls, collision magic weapons often have little effect. If you want to deal more damage to the demon soul, you mainly have to rely on spell damage.

Of course, spiritual spells count, and those magic weapons with offensive spells are also good. But in fact, the natal true fire of instrument cultivation is the best weapon to deal with demon souls. Of course, high-level fire methods are also possible, but in fact, because of certain historical factors. The fire attribute spells of the cultivation realm are not particularly strong. Therefore, except for the kind of monks with pure fire attribute qualifications, the vast majority of spiritual cultivators will still choose to cultivate other spell directions. And the monks with pure fire attribute qualifications generally chose the direction of instrument cultivation.

The natal true fire of the instrument cultivation is quite restrained by the demon soul. Especially those alien fires that have an advantage in strength, the restraint of demon souls is even more obvious. Lin Feng and Eldest Sun Hao each sacrificed a large amount of Ghost Light Ember Burning Fire and Purple Sky Burning Thunder Flame, and quickly enveloped the tiger demon soul inside. The tiger demon soul instantly began to howl miserably.

As the strength of the demon soul increases, the demon soul will gradually be able to condense an entity that is not weak. Although it is composed of demon souls and spiritual power envy condensation, in fact, it is not much different from physical demon beasts.

The tiger demon soul that Lin Feng and the others encountered exuded spiritual power fluctuations at the level of a heavy heaven in the Earth Yuan Realm. The demon soul of this level, coupled with being restrained by the alien fire, didn't last long at all, and was defeated by Lin Feng and Changsun Hao. Wei Ruye is also a cultivator, but the alien fire she uses is only at the top of the Yellow Order, and there is still a big gap between the effect that Lin Feng Changsun Hao can play.

As for Fang Kun and Ji Sihan's words, his offensive is actually only equivalent to talking better than nothing. Give them enough time, and it shouldn't be much of a problem for each of them to defeat the demon souls of the same level. But if you want to improve efficiency, it's a bit difficult.

In fact, when the Ghost Ember Flame had just wrapped the Tiger Demon Soul inside, Lin Feng thought that he could actually use the Nether Ghost Fire, which was known to be extremely restrained against evil cultivators and demon spirits.

Under normal circumstances, Netherfire can only be used for soul attacks. There is no achievement at all in alchemy refining, even in terms of improving the combat effectiveness of weapon cultivation, it is far inferior to other Xuan-level alien fires.

However, the Netherworld Ghost Fire was not at the bottom of the Xuan-rank Alien Fire, but it was ranked the nineteenth among the thirty-six Xuan-Rank Alien Fires. The main reason is that the Netherworld Ghost Fire has a great degree of restraint on evil cultivators and demon spirits.

The Ghost Ember Flame had already been sent out, and Lin Feng didn't say anything. But when he encountered the second demon spirit, Lin Feng stopped everyone.

This time, it was a human demon soul who had reached the Earth Yuan Realm Double Heaven Realm.

Lin Feng directly sacrificed the Netherworld Ghost Fire, which made several people, including Eldest Sun Hao, a little surprised. Lin Feng has more than two different fires, that is, among the closest people, few people know about it. It's really this ability, it's amazing.

The description of the ghostly fire in "Purple Sky Strange Fire Spectrum" is like this: dark shadows, white and ghostly. Feed on the soul, and the infant transforms into a shape. The black flame envelops the image of the pale flame heart, which has a miraculous effect on the soul of the primordial infant.

"Shadows, darkness. This sentence is actually the same meaning as the later vernacular, both of which describe the image of the Netherworld Ghost Fire. In the past, Lin Feng was interested in "feeding on the soul and transforming the primordial baby." This sentence is still a little confused, and later there is the teaching of Old Man Long. Lin Feng finally figured out the specific meaning of this sentence.

This sentence is actually to be explained together. The Nether Ghost Fire uses the Alien Soul and the Primordial Infant as nourishment, and after devouring the Alien Soul or the Primordial Infant, the power of the Pyreom Ghost Fire will be significantly improved on the original basis. Alien soul is another name for demon soul in the cultivation realm.

This boost is time-limited, and when the soul power of the devoured soul is exhausted, the power boost will return to its original state. But all in all, it's always a nice trait to be able to increase the power to a new level in a short period of time.

And "transformation" refers to after devouring a foreign soul or a primordial infant. Nether Fire has the ability to transform into the latter's image. For example, if the Nether Ghost Fire devours the previous Tiger Spirit, the Nether Ghost Fire can transform into the same image as the tiger, and the spiritual power fluctuations and even soul fluctuations emitted are extremely similar.

And if it was to wrap Lin Feng himself in the Nether Ghost Fire, and then transform this image. From the outside, Lin Feng would become exactly the same as this tiger. If an opponent of the same level does not practice the pupil technique, nor does he have other magic weapons that have a delusion-destroying effect, I am afraid that it will be difficult to see the flaws in the image or spiritual power fluctuations.

Of course, it is more difficult to disguise yourself as another monk with the Transfiguration function. After all, the grade of the ghost fire is still relatively low, and the image formed is inevitably a little dull. If it's a demon beast, others won't be able to see anything. If you disguise yourself as another human monk, your dull expression can easily arouse suspicion.

The five people present were all masters of the Earth Yuan Realm, among which Fang Kun and Wei Ruye had wandered around the periphery of Zhongzhou. I have personally seen the new version that is further behind than Lin Feng's "Zixiao Strange Fire Spectrum". And the eldest grandson Hao and Ji Sihan have also read the information about the different fire in the Zixiao Strange Fire Spectrum.

Lin Feng originally left the spirit of "Zixiao Strange Fire Spectrum" with Uncle Duan Yun. And since Eldest Sun Hao and Ji Sihan are now one of the strongest people in Chiyun Peak, of course they are qualified to read the information in the Purple Sky Strange Fire Spectrum.

Soon after Lin Feng sacrificed the Nether Ghost Fire, several people confirmed the identity of this strange fire based on the Nether Ghost Fire's really special appearance characteristics.

Of course, surprise is surprise, but even Wei Ruye didn't have much covetousness. Nether Ghost Fire is a relatively special situation, ranking medium among the Xuan-level Alien Fires, and ranking nineteenth is also reasonable. However, the vast majority of instrument cultivators do not force the Netherworld Ghost Fire very much. If you subdue the Nether Ghost Fire, it is almost equivalent to giving up alchemy and refining weapons. Even in terms of combat effectiveness, there will not be much improvement under normal circumstances. Therefore, those cultivators in the cultivation realm who don't often deal with demon spirits or evil cultivators, even if they encounter the Netherworld Ghost Fire, they will also consider it.

And soon, several people thought of Lin Feng's soul attack ability.

Lin Feng possessed the ability to attack souls, which was clear to everyone present. And before, Ji Sihan and the others had actually guessed, guessing that Lin Feng's soul attack ability should come from that pot-shaped magic weapon with a somewhat quaint appearance. After all, Lin Feng would sacrifice that pot-shaped magic weapon almost every time he fought, but he didn't use that pot-shaped magic weapon to directly send out any formulas. A few of them, who were already familiar with Lin Feng, naturally linked Lin Feng's soul attack ability to the Extreme Dao Immortal Pot.

And now, the situation is even clearer. That pot-shaped magic weapon must have been used to control the Netherworld Ghost Fire. It was also by relying on this Netherworld Ghost Fire that Lin Feng had the ability to attack with his soul.
