Nie Lingfeng had already guessed that once he encountered any big danger, these demons who were "not afraid of death" would definitely not hesitate to blow themselves up and use them to blow up the enemy. Therefore, he must move quickly, and he must kill with one hit.

At this time, Nie Lingfeng didn't want to continue to flee to the side, because once he blindly fled, then there would definitely be more and more demons behind him, and even he would lead them to the entrance of the third layer, and then it would be troublesome!

"Kill them!" Nie Lingfeng suddenly made up his mind, the purpose of his doing this was firstly to destroy the other party's living force, and secondly, to scare the demons who were chasing after him.

The three-headed demons in front of them frequently looked back as they ran, and the instincts formed in the countless battles in the underground treasure trove told them that they had been targeted by something dangerous!

However, no matter how the divine consciousness of these demons looks, they just can't find the hiding place of their opponents.

The demon that flew at the end, the moment it turned back, a cold light with an eerie and destructive aura suddenly rushed past him, and even, a black light suddenly came out of its abdomen, and before it could even scream, it fell to the ground, and even, its body turned into a dried skeleton.

After the most powerful Tribulation Period Demon was killed, the remaining two-headed demons were not Nie Lingfeng's opponents, and the moment he rushed over, the three-headed demons had already fallen to the ground one after another, only making three dull landing sounds.

At the same moment, the dozen or so demons that were tracking Nie Lingfeng behind had stopped, indeed, the combat power displayed by Nie Lingfeng was really amazing! Even a mid-tribulation demon can't kill a three-headed demon in such a short period of time, which also shows that Nie Lingfeng's danger is greater than that of an ordinary mid-tribulation demon.

Don't think that demons don't have a mind and don't know how to think about problems. After countless years of fighting and grabbing territory, their thinking ability is not weak! Otherwise, it will not be possible to achieve cultivation above the Tribulation Period.

Speaking of which, the demons here are born with the cultivation of the Yuan Infant Period, and as long as they are adults, they can reach the cultivation of the Yuan Infant Period. Once they had cultivated for thousands of years and swallowed a few poisonous blood plants, then there would be absolutely no problem with the Advanced Tribulation Stage.

Just like the dragon is born without mana, but once the dragon becomes an adult, its cultivation can reach the ascension period of human beings, and it can soar in the universe, if it has some cultivation resources, it is not impossible to become a scattered immortal, even. Some dragons can also cultivate to the Great Luo Golden Immortal Stage of human beings and become invincible existences.

Seeing that the demons behind him were frightened by themselves, Nie Lingfeng hurriedly rushed out of the range of their divine senses, and then slammed into the ground.

Although the ground here is hard, Nie Lingfeng is already a monk in the Tribulation Period, even if it is steel, he can completely rush into it.

Although Nie Lingfeng hid, but. He is not trying to escape from the other party, but to destroy the demons who want to continue to pursue him.

Truly. If there are so many "tails" behind him, if there are more and more tails behind him, he may not be able to reach the entrance of the third layer, and he will be swallowed by them to the bone, who knows how many demons at the peak of the Tribulation Period are there?

Maybe it was because after those demons checked the corpses of the dead three-headed demons, a few demons of the lower grade of the Tribulation Period and all the demons who cultivated below the Tribulation Period left, and only the injured Demon of the Peak and Intermediate Grades of the Tribulation Period and the five-headed demons of the lower grade of the Tribulation Period were left.

With the roar of the peak demon of the Tribulation Period, the remaining six demons were led by it. Continue to rush towards the location where Nie Lingfeng was hiding.

"Whew! ……”

"Boom! ……”

With an earth-shattering loud noise, the surrounding space began to tremble, but after finding no trace of the enemy, the seven-headed demon suddenly stopped in amazement. And very confused to communicate with each other.

Indeed, in this underground treasure house, the speed of the demon is much stronger than that of the human cultivator, if Nie Lingfeng's cultivation is only the lower grade of the Tribulation Period, then the demon at the peak of the Tribulation Period can definitely easily catch up with him and hit him.

However, Nie Lingfeng is not only not an ordinary low-grade cultivator in the Tribulation Period, but also has a sky-breaking flash on his body that increases his speed, and even has a very sharp Shape-shifting and Shadow Changing Dafa, however, there is definitely no problem for the demons at the peak of the Tribulation Period to catch up with him, but the demons at the peak of the Tribulation Period have already been seriously injured, and their mana may not even be as good as the high-grade demons in the Tribulation Period, so this gave Nie Lingfeng a chance to escape.

If all the attacks of the seven-headed demon fell on Nie Lingfeng, he would give away even if he had three lives, after all, in this underground treasure house, many of Nie Lingfeng's methods could not be used, including his slave Jin Zhuang and his Ten Thousand Soul Banner.

And after a short period of communication, the seven-headed demons obviously reached an agreement and began to attack around at random, they obviously didn't believe that Nie Lingfeng would leave here in such a short time.

Seeing that some demons had gradually shifted the scope of their search to the ground, Nie Lingfeng suddenly became anxious, although his invisibility cloak was powerful, it could not resist the attack of mana, nor could it eliminate the attack of mana. As a result, his attention began to focus.

The mid-tribulation demon had now reached five or six zhang in front of Nie Lingfeng, and was attacking the ground while walking in his own direction.

Speaking of which, Nie Lingfeng also had to admire these demons, they could actually think of this trick, even human cultivators sometimes wouldn't pay attention to the underground!

Entered! It's close again!

At this time, the distance between the demon and Nie Lingfeng was only about a zhang, and it was possible to slap Nie Lingfeng's body at any time.

Just as the demon turned around and wanted to attack the location where Nie Lingfeng was hiding, suddenly, a gray cold light appeared on the ground without warning.

"Brush! ......" There was a soft sound, and the cold light was like a gray lightning bolt, and like a sudden flying arrow, piercing the place between the demon's legs!

In the short space where the cold light passed, a thin spatial crack as dense as a spider's web appeared! This is the spatial fluctuation caused by speed! Because this is inside an enclosed space, if your speed is at the extreme. Then, the spatial crack will appear, and if this is the monk performing teleportation, then, the monk will definitely be swallowed by this spatial crack, but. Nie Lingfeng just tried his best to sacrifice the Han Jiao Sword!

As a top-grade magic weapon, the Han Jiao Sword can fully withstand the destruction of the spatial crack, but as the spirit of the Han Jiao Sword, the "Han Jiao", because of its speed, it was not lightly injured, but fortunately, the Han Jiao Sword had completely penetrated the demon's body and emerged from the top of its head.

If not by surprise. It was obviously a little difficult for Nie Lingfeng to kill the other party in seconds, but in this way, he had already bought himself a little time.

Indeed, the mid-tribulation demon who was attacked to death was only a blink of an eye, and before the other demons had paid attention to this, Nie Lingfeng had already rushed out of the ground. Running to the side, the Han Jiao Sword now couldn't care about devouring the other party's essence blood. It also disappeared in the blink of an eye.

"Whew! ……”

Hearing a strange noise, the other demons looked around. Finally, the demon at the peak of the Tribulation Period saw the blood coming out of the head of the mid-grade demon of the Tribulation Period.

The blood was like a small fountain, spurting, and if the Han Jiao Sword devoured the other party's essence blood, maybe the other demons wouldn't notice anything wrong by now. After all, because Nie Lingfeng's attack speed was too fast, the dead demon was still standing on the spot like a statue before he died.

"Let's go! …… Let's go! ......" The sound of blood falling on the ground was clearly audible, but. All the demons froze, it's not that they don't want to catch the enemy who can be invisible, it's just that the other party is too powerful!

The demon at the peak of the Tribulation Period didn't believe that he could kill his dead companion in one move while he was injured! In other words, the other party's cultivation can definitely be worthy of the current self! He is definitely a monk who has cultivated above the level of the Tribulation Period.

Therefore, none of the demons dared to continue attacking, they all stopped unconsciously, at first they felt that the other party's cultivation would definitely not reach the top grade of the tribulation period, therefore, these demons united, in order to snatch back the poisonous blood grass, and secondly, to kill the other party to avenge the death of their companions, but now that they found that the other party's cultivation was much higher than their own, they all began to retreat one by one.

The demons are not united with each other, and even, sometimes, they will fight each other, but, after encountering a common enemy, they may join forces to fight the enemy, but now, it's not that they don't want to unite, it's because they're afraid, afraid that the guy who can kill the mid-grade demon in the calamity period will cut off his head.

"Wow! ...... "In less than a breath, all the demons on the scene disappeared, and they did not pursue Nie Lingfeng, but fled separately.

If Nie Lingfeng knew that he would scare them away if he killed one of the other party's demons, then he would not run for his life if he said anything! ~ Because he inadvertently got into a dark space.

This is not a fixed space, but a chaotic space, the surroundings are pitch black, even if Nie Lingfeng uses his divine sense, he can't see what kind of place this space is, what is floating in the sky above this space!

However, Nie Lingfeng had already sensed the danger, and a very big danger was beside him. So, he began to dodge constantly, trying to avoid the fluttering objects.

Nie Lingfeng kept twisting his body all the way, interspersing through the gaps in those black objects, but it was pitch black from front to back, left and right, and there was no way out, and even, so far, Nie Lingfeng was exhausted, but he still couldn't find an exit.

In desperation, Nie Lingfeng could only swallow a Gathering Spirit Pill while beginning to think about where he had entered.

Those fluttering things covered the sky and the sun, and even Nie Lingfeng's divine sense couldn't penetrate it.

"Ah......h

"Who the hell is it?" Nie Lingfeng couldn't help frowning, although this voice was a little familiar, but he couldn't remember it for a while.

Since there is a sound ahead. Maybe there was more than one person, Nie Lingfeng immediately rushed towards the position where there was a sound, and just after he had moved three or four divine positions in his footsteps, he suddenly heard another person's voice, which was a woman's voice, although tired and weak. However, this is not a scream before death, but a scream: "Quick, hidden breath!" ……”

"Boom! ......" Nie Lingfeng was listening to the female cultivator's shout, but accidentally bumped into a flickering black shadow.

With a collision, Nie Lingfeng only felt as if he had been struck by lightning, as if he had been anesthetized, his whole body was crispy and soft, and he was dizzy, but it was only a moment later. That feeling is gone.

However, immediately after, a large group of black shadows rushed towards him, originally there were very few black shadows floating in front of Nie Lingfeng, but after the impact just now, there were more and more of those black shadows, densely packed as if they were about to wrap Nie Lingfeng.

Nie Lingfeng knew how powerful the other party was. I don't know what these black shadows are, so. She hurriedly retreated some distance, and as the nun shouted, not only did she hide her figure, but even her breath was hidden.

Sure enough, there were fewer and fewer dark shadows around, even. Nie Lingfeng was also shaken by a misty light.

Finally, he figured out that he had accidentally rushed into the territory of the poison.

There has been an introduction on the jade cylinder, and this second layer is full of poisonous gases, poisons, and demons, but. Nie Lingfeng hadn't encountered any poison since he entered the second layer! However, the jade tube only explained the second layer of poison, but it did not explain what the poison was, and even its shape, appearance, and breath were not described, apparently the monks who had seen the poison were all dead, or they did not know what the poison was in the end.

Nie Lingfeng wanted to continue walking forward and join the female cultivator, because he had already heard that the female cultivator was the little Feng Zhenren of Fengming Pavilion!

Due to his experience in avoiding poisons, Nie Lingfeng advanced a distance of four or five zhang after a while, but now there is a disadvantage, that is, Xiaofeng Zhenren has also found a trick to avoid these poisons and has hidden his breath, so Nie Lingfeng has not found any trace of her after walking such a long distance.

"What should I do?" Nie Lingfeng is now also beginning to have six gods without masters, and he is now completely disoriented, because in this poisonous space, his divine consciousness cannot penetrate their bodies at all, that is to say, his eyes can only see a few tens of centimeters in front of him, and he can't see or feel other places at all.

And how big this poison space is Nie Lingfeng doesn't know, now he has three wrong choices, and there is only one right choice! That is, the place where you enter should be the closest to the exit, and the other three places are unknown, and no one knows how far away.

However, now Nie Lingfeng didn't know where he was coming in, especially in it, he wanted to avoid the attack of the poison, and now he was completely lost.

After walking for a while, Nie Lingfeng was so tired that he was sweating profusely, and even his mana was a little empty, so he stopped cautiously.

First, he swallowed a Gathering Spirit Pill to restore a little cultivation, and then he began to calculate, if he went on blindly like this, maybe he would not be able to get out of this poisonous array in this life! Is there any way to rush out quickly?

"With the Hanjiao Sword?" Nie Lingfeng frowned and thought for a moment, then shook his head, before, the spirit of the Han Jiao Sword had already been a little damaged, and it was not appropriate to use it against the enemy immediately! However, I don't understand what these poisons are, what they are afraid of, how can I escape?

With fire? Nie Lingfeng thought about it, and quietly sacrificed a flame talisman from the space ring, although this was a medium-grade talisman, but inside it was sealed a heavenly fire that a monk of the Tribulation Period had cultivated, although this Heavenly Fire was not enough to kill the monks of the Tribulation Period, but no one in the Yuan Infant Stage dared to touch half of it!

"Whew! ......" The flame talisman rose into the sky and rushed towards Nie Lingfeng's side, but the powerful heavenly flame only rushed out of a distance of two meters and disappeared completely, as if it had never appeared, and the surrounding space did not even fluctuate at all.

"It's over!" Nie Lingfeng sighed and looked at his spatial ring again.

"Huh? Flying needles? Nie Lingfeng saw at a glance the set of medium-grade spirit weapon flying needles that he had obtained from Duan Qingshi's treasure house! Although this set of flying needles is not powerful, it is better because it has a large number, and it is also a "magic weapon" that I have already refined! It is obviously impossible for him to refine the magic weapon again, with this set of flying needles, Nie Lingfeng suddenly became confident, he couldn't imagine that this treasure that he hadn't used before would become his life-saving "medicine" today.

Although the magic weapon of the flying needle belongs to the magic weapon of sneak attack in the immortal cultivation world, it is very suitable to use here, because he can't see the poison, and the poison can't see himself, as long as he can catch or kill a poison, then he will study a way to crack this poison array! (To be continued......)
