The Demon Domain battlefield here is slightly different from the place where Li Fei and the others entered from Baisha City, except that the demonic energy is stronger, the teleportation array does not have special protection, and there is not a single demon clan to be seen. www.biquge.info It is clear that there are often monks entering the Demon Domain Battlefield through the teleportation array here, and the nearby demons are emptied.

As soon as Li Fei and the others left, Dongfang Bisheng and the others had already arrived, and the five of them didn't stay long, but after a little sense, they tore open the space one after another and left from different directions. Not long after, a large number of disciples of the Star Saint Academy also arrived, and soon disappeared in groups of three or five in the rolling demonic qi.

Li Fei's current strength is not the same as the last time he entered the Demon Domain battlefield, and he has almost improved to a big realm, Xiang Cheng and the others are similar, all of them have advanced from the realm formation stage to the domain transformation stage, and their strength has improved by leaps and bounds, especially their exercises have been greatly improved, and there has been a qualitative change.

In addition, in terms of treasures, everyone has also carried out a big upgrade of "shotgun for cannon", which is basically a medium-grade magic weapon level, although most of the treasures, everyone can only barely control them, but the power is so strong that even they themselves were taken aback!

If they hadn't joined the Star Saint Academy, everyone's exercises had not improved, and these high-quality treasures, except for Li Fei's control, Xiang Cheng and the others could only stare dryly, but now everyone has come out to take refuge, and they are preparing to work hard to improve their cultivation, and the treasure level is a little higher, which is just right.

After a series of space shuttles, Li Fei and the others soon came to a million miles away, because of the demonic energy, the divine thoughts were greatly restricted, and everyone did not have to worry about being caught up by some ill-intentioned disciples, so they decided to slow down and explore slowly, after all, the demonic energy here is so pure, once they meet the demon clan, the strength of the other party must be very strong.

Hua'er suddenly said curiously: "Brother Fei, look at that tree is so strange! In a place like the Demon Domain Battlefield, there are actually green plants, and the growth rate is amazing......

Li Fei was about to say something to remind, but the small tree, which was originally only one person high, suddenly soared, turning into more than ten zhang high, trembling, and countless leaves turned into sharp blades, sweeping towards everyone at a very fast speed!

At the same time, countless black "tree roots" almost broke out of the ground at Li Fei's feet, like countless demonic hands, entangled around Li Fei, as if they wanted to drag him into the ground.

"Eagle insect skills, I don't know whether to live or die!" Li Fei roared angrily, and a thunder control fist had already blasted out, ignoring those sharp blades and demon hands, the last hit came first, hitting the trunk of the tree!

The thick arc of electricity slammed into the trunk of the tree, like a nemesis descending, not only did all the sharp blades and magic hands retreat urgently, but even the trunk of the tree was rapidly retracting!

After the strength soared, Li Fei was looking for someone to try his skills, and now he found that the strength of this monster was just right, how could he let it escape, roared, mobilized the power of the field, and increased the power of the lightning control fist, a pair of giant hands composed of electric arcs appeared, grabbed the trunk of the tree and pulled it out violently!

The big tree was uprooted without any suspense, revealing a bottomless hole, and the thick demonic qi gushed outward like a spring, but if you look closely, the demonic qi is also mixed with a faint gray qi, and the amount of gray qi is very small, and it is easy to be covered by the demonic qi.

Li Fei threw away the rapidly withering old tree, and said with interest: "You are on guard all around, I feel that there is something strange down here, just now this tree was just controlled by a mysterious force, there should be a big fish below! For the sake of safety, I will go down alone to see what old monsters can be under this ground." ”

Yue'er said excitedly: "Brother Fei should be careful, maybe there is a heavy treasure, we will set up a large array on it to prevent it from escaping." ”

Xiang Cheng cautiously added: "The boss is powerful, and ordinary monsters are naturally not afraid, but in case of encountering a particularly powerful old monster, we still have to put safety first, draw it out, and we will use the formation to destroy it together!"

Then, after everyone discussed for a while, Li Fei activated the Tianchen Shield, turned into a dazzling ball of light, and rushed into the demonic qi, while Xiang Cheng and the others arranged the formation within a radius of dozens of miles outside.

It is worth mentioning that when Xiang Cheng and others exchanged for offensive and defensive treasures in the contribution hall, Li Fei was not idle, after comprehensive consideration, he did not exchange for general offensive and defensive treasures, but spent a lot of money to exchange for a set of array flags of the same medium-grade Tongtian magic weapon level, called "Demon Suppression Array". Due to the rarity of the powerful array flag, although it is also a medium-grade magic weapon, the price paid by Li Fei is much more than Xiang Cheng and them, several times more than them!

Although the name of the formation flag is very ordinary, it is powerful, and if the power of the presiding formation is strong enough, not only can it destroy the powerful monsters below the Demon Lord, but even the Demon Lord can be trapped for a moment. Of course, if you want to trap the Demon Lord, the current strength of Li Fei and the others is obviously not enough.

At first, it was quite normal, but after descending hundreds of zhang, Li Fei felt the temperature drop suddenly, and countless low sounds echoed in his ears, which was extremely harsh! However, the passage became spacious and regular, and it twisted like a labyrinth, leading to the depths of the underground.

As he got closer and closer to the goal, Li Fei also slowed down, and as he went deeper and deeper, he felt that this place was like an ancient tomb, and his interest grew.

Although the underground passage was still very dim under the light of the battle armor formed by the Heavenly Dust Shield, it had no effect on Li Fei at all, and the powerful divine thoughts were clearly sensed, and some ghosts and ghost generals began to appear sporadically. However, for these ghosts that are equivalent to the infancy stage and the boundary formation stage, Li Fei naturally will not pay attention to them, and they can be easily eliminated with a single blow.

These ghosts, I don't know how they were formed, at least they were at least a monk in the realm maturity stage in front of them, and after death, their souls were locked in time, and after some sacrifices, they turned into powerful ghosts. Although the demonic qi is not very compatible with ghost cultivation, it can barely be cultivated, but the speed is extremely slow.

As the ghosts become more and more dense, the evil qi becomes stronger and stronger! These evil qi can not only erode the monk's defense, but also affect the monk's state of mind, which is quite powerful! The formation of evil qi is relatively complicated, in addition to the death of a large number of monks, there must also be extremely powerful resentment, after a long time of brewing, coupled with a certain amount of chance, it can be formed.

With Li Fei's current level of depth, if it is an ordinary monk, even if there is a monk in the middle stage of the Transformation Domain, I am afraid that he will not be able to withstand it, and only the masters of the late stage of the Transformation Domain can rely on their strong strength and not be afraid of the threat of evil qi.

However, Li Fei was very relaxed, the battle armor formed by the Tianchen shield could isolate the evil qi, and after reaching the Tianchen state of mind, he was not afraid of the impact of the evil qi on the state of mind.

Li Fei advanced for a short while, and found that there were more and more ghosts, and even formed a huge army, the most suspicious thing was that not all of these ghost beasts were ghosts, and there were a few monsters, and their strength had reached the level of the early stage of the Demon Saint.

Seeing that Li Fei was still on a rampage, the three demons of the early stage of the Demon Saint joined forces with countless ghost creatures to send out a powerful invisible "Devil Resonance", and the surrounding incomparably hard stone walls instantly dissolved, forming a huge space!

However, Li Fei still did not change his face, and used the Tianchen battle armor to block the opponent's attack, and then released the domain, and all the ghost things and the three demon saints were all involved in the domain, and the Tianchen sword array was twisted, and all the ghost things and demon saints were turned into the "fertilizer" of the domain.

Emptied this army of ghosts, the passage was instantly cleared a lot, Li Fei didn't want to be entangled with this kind of low-level goods, a few teleportations, crossed thousands of zhang, killed countless ghosts and a small number of monsters, and appeared in an upward passage.

"Hehe! It's just the early stage of the Transformation Domain, and it is indeed a bit of a means to be able to ignore the Devil Combination Formation! However, that's all you have to do, give me everything you have! Haha......" A white-haired demon saint who was about the same height as a monk was condescending, blocking Li Fei's way, with a look of disdain.

Li Fei looked at this Demon Saint, and his expression became solemn! Because this is a master of the late stage of the Demon Saint, although this demon may be weaker than Roland Soul in terms of strength, but this is a Demon Domain battlefield, if Roland Soul fights this demon, I am afraid that the possibility of defeat is greater.

Li Fei strengthened his vigilance and said tentatively: "You are not a real demon!

"It's ridiculous, death is on the verge of death, and you're still in the mood to talk about me! Go die, your flesh and blood should taste good!" The white-haired Demon Saint's face twitched slightly, and then it became hideous, and with a loud roar, a green horse slashed towards Li Fei!

Generally speaking, after the monk is demonized by the powerful demon race, he will naturally become a member of the demon race, but the basic body shape will not change, but the strength will be stronger! Of course, the disadvantage is also obvious, that is, the progress of cultivation is extremely slow, unless it is the original demon cultivation.

Sensing that the power of the green match was not very strong, Li Fei pointed with his hand, and the Yunhai Sword met it, and the two sides only held on for a moment, with a wail, an emerald green flying sword appeared in its original form, and the Yunhai Sword flashed and slashed at the head of the white-haired demon saint, splitting into two!

Li Fei was greatly surprised by such an easy way to defeat his opponent, and after he collected the Yunhai Sword and the Green Sword, he carefully looked at the corpse of the White-Haired Demon Saint and found some clues.

It turned out that this white-haired Demon Saint had been banned a lot, and it seemed to be quite powerful, but in fact, it was at the level of the peak of the middle stage of the Demon Saint, and it was naturally vulnerable to the current Li Fei!

Li Fei popped out a wisp of true fire, turning the corpse of the white-haired demon saint into ashes, and a blue orb the size of an egg was revealed, and the true fire did not damage it at all.

Putting the blue orb into his hand, Li Fei looked at it curiously in all directions, wondering in his heart: "After the monk is demonized, he is still a human being in nature, and it is generally impossible to have a magic crystal! Even if the situation is special and the magic crystal is produced, it will not be without demonic energy! What is this thing?"
