It's just that Nan Liuyue didn't think about it for a long time, it's not that Nan Liuyue found any clues and was ready to move forward, but just when Nan Liuyue carefully examined the hand at the entrance of the cave, the second hole on the left suddenly surged with purple qi, and suddenly a figure flashed, the figure was extremely fast, and there was a dark red light around his body, but even so, this person was already very embarrassed, and there were scars everywhere on his body, although it didn't look like an eye, but his robe had been torn and scarred everywhere.

However, Nan Liuyue didn't take the opportunity to make a move, because the person who came was none other than the underworld, although he was not a person all the way, but in this situation, the underworld could barely be counted on his side, and the other party had just flown out of the demonic cave, so he must know the situation in the cave very well, and he could just listen to the real situation in the cave.

On the other side, after the underworld rushed out, after a short period of doubt, he saw Nan Liuyue who was looking at him, and couldn't help but smile bitterly, and with a move of his hand, the dark color light slowed down and flew away, it turned out that it was the dark red magic weapon that was released on the first layer just now, and the magic weapon slowed down, but it was a magic weapon in the shape of a bird, but what it was, but it was impossible to judge.

"Hey~!It turned out to be Brother Le, hey, it seems that the luck of the Taoist friends is better, and it looks much safer here. The Evil said with a sigh, a hint of envy in his tone.

"Oh? Nan Liuyue smiled slightly, and a green mang popped out of her fingers, and the green mangs slowly flew to the ground protrusions, and turned into a seedling of the Zhitian Tree between breaths, although it was a seedling, but the Zhitian Tree was already huge, so this sapling was already not small, and the whole body was emerald green, showing vitality.

On the other side, the underworld obviously didn't see Nan Liuyue's intention, and not only frowned slightly.

Nan Liuyue didn't say much, but motioned with interest to look at the Heavenly Tree seedling.

The underworld was obviously puzzled, but he still looked at the Zhitian Tree seedlings, carefully observed, and seemed to want to see something wrong from the Zhitian Tree seedlings, after all, he summoned the grass and trees so empty-handed, although he had seen Nan Liuyue perform it, but the soldiers didn't understand the reason.

However, just when the underworld looked carefully, the protrusion on the ground erupted again, and countless pitch-black sap rose into the sky again, and the huge torso of the Finger Sky Tree was instantly pierced through countless black holes, and this was obviously only the beginning, after the hole, the trunk began to take the black hole as the center, and suddenly died, and then turned into the same pitch-black sap, a few breaths, the entire Finger Sky Tree seedlings were dissolved, and the sap flowed to the ground, and after a few breaths, the black sap on the ground once again all seeped under the ground and disappeared, as if nothing had happened。

Although the time interval between the eruptions of this pitch-black poisonous juice was very poor, it was extremely dense, and what was even more intriguing was that except for the place under your feet, when you looked up, the entire cave was covered with this kind of ground protrusion, and there was no way to avoid it.

Seeing this scene, the underworld suddenly gasped, not only sighed: "It turns out that this is not a safe place, it seems that this second layer is not only a distorted space, but also a dangerous place everywhere~!"

"Yes, just now there was a guard who slaughtered Liangfeng's relatives who died here. Nan Liuyue nodded.

"I see, but Brother Le can be safe and sound, it seems that Brother Le is still smart, and he can see the difference here, of course, he is much smarter than me. The Evil of the Dead exclaimed, smiling wryly and looking at his body.

"Brother Hades is too much, but your last sentence is exactly what I want to ask, the Hades Daoist rushed out of the cave, I don't know what the scene is in the cave?" Seeing that the Hades knew the crisis here, Nan Liuyue began to ask officially.

"There is a relatively wide passage on the other side of the channel, but it is full of a strange red mist, this mist seems to be alive, can be condensed into any shape, hit it ineffective, hit it invisible, there is no way to start, I this magic weapon Feiyan throws into his arms, the ability to defend the treasure, and can not block the attack of these invisible substances, can only look at the key points, embarrassed to dodge, and finally had to break into a hole full of demonic energy, not only did I meet Brother Le you through it, this is also my life should not be extinguished, otherwise it will be a real crisis if I am in danger again。 ”

"It's like a strange red mist like a living thing, is there really such a thing?" Hearing the words of the underworld, Nan Liuyue couldn't help frowning and thinking.

"It's hard to believe, yes, it's really this weird thing, you can take a look. The Evil nodded.

"What do you mean by the Daoist friend of the Underworld, do you need me to investigate?" Nan Liuyue's eyebrows condensed again, and she looked at the Dao of the Underworld in confusion.

"This is not necessary, although it was a crisis just now, but I did ingest some, enough for Taoist friends to observe. The Evil laughed.

With that, with a wave of his hand, a transparent bead wrapped in a small cloud of red mist appeared in front of Nan Liuyue's eyes.

As soon as this thing came out, Nan Liuyue was secretly vigilant in her heart, and she could still think of studying the source of the crisis in the crisis situation just now, and this alone was enough to show that the body and scheming of the underworld were terrifying.

And Nan Liuyue believes that if it weren't for this person seeing that his Nan Liuyue's location is also a Jedi, he would never take out such an important thing to share, and now take it out, it's not that he is kind, but he really doesn't have the confidence to deal with this weird red mist like a living thing.

However, Nan Liuyue naturally couldn't let go of such an opportunity to explore the other side, and with one move, the ball that trapped the crimson mist flew in front of Nan Liuyue's eyes.

These crimson weapons are really as the underworld said, like living creatures, although they are trapped by the ball, and only slightly, but these crimson weapons are rampaging in the ball, suddenly turning into sharp blades, suddenly turning into spikes, and even turning into strange monsters, constantly impacting the ball that traps it, but these fogs are too little, and the power is trapped again, so naturally they can't break through the ball, but Nan Liuyue believes that if a large number of this red mist is so spiritual, then the passage is really terrifying.

"Le Daoyou, with Daoyou's amazing intelligence, can you see what's wrong?" After waiting for a while, the Underworld Evil hurriedly asked Nan Liuyue.

"The Evil Daoist is too famous, the Daoist Friend was born in the Four Great Demon Sects, and he has a wide range of experience, how can I be able to look forward to it as a wild cultivator? Nan Liuyue shook her head.

Hearing this, he couldn't help but feel a little more melancholy in his heart, he also knew that the Leliu in front of him was right, he had an excellent background in the underworld, and the knowledge of the cultivation realm that he could contact was naturally the top, what he couldn't see, the chance that Leliu in front of him could see it was indeed extremely small.

However, Nan Liuyue's next words gave birth to a glimmer of hope.

"But I was born in the mortal world, and I know some folklore, according to legend, there is a harmful thing called blood Gu in the folk, I haven't seen this kind of thing, but I heard that blood Gu is a kind of worm that is integrated into the blood, and all the blood is turned into a sharp weapon for killing, and this blood Gu can turn the blood into the kind of living thing we see in front of us, killing people invisibly. I just don't know if this crimson mist is such a thing. Nan Liuyue said as she looked at the things in the ball.

"Oh, is there still such a powerful Dao method in the mortal world? It seems that I am really lonely and unheard of, I wonder if Daoist friends know any way to restrain this thing?" asked in surprise.

"Hades Daoists, first of all, it's hard to say whether it's a blood Gu, and even if it is, I'm afraid it's not as simple as a blood Gu in the mortal world, the blood Gu in the mortal world is aimed at mortals, and I have never heard of it being able to deal with monks, and besides, I have no chance to learn this technique, I just heard about it, and I took it out for the Daoist friends to refer to, Daoists are scholars and people, and there will be a better way to deal with this thing. Nan Liuyue shook her head.

Hearing Nan Liuyue say this, there was a wave of disappointment again, but he finally had a little clue, coupled with the polite compliment in Nan Liuyue's words, so that the underworld not only calmed down a lot, but also began to seriously think about what was in front of him.

"If this thing is a blood Gu, is it blood over there? No, so the passage over there is a bloodline? How is this possible?!What can the bloodline of something be so wide? You and I feel that the passage is wide when we walk in it?! And the walls of this cave are clearly rocks, this doesn't make sense~!" After thinking about it seriously, he not only frowned and said.

"I don't know about this, but I think this thing is very similar to Blood Gu, whether it's or not, I can't be sure. Nan Liuyue shook her head.

"That's it~!Let's count him as a blood Gu, then this thing should have been a refining worm, and since this thing can see the blood melt and live in it, it must be assimilated with blood, so it can be hidden invisible, and can control the blood, and because of this, there will be blood activation, killing people in the invisible, so, I guess the key to this technique is the refining insect, as long as this insect can be summoned to kill, it will definitely be able to extinguish these crimson mist invisible. The Evil said earnestly.

Hearing this, Nan Liuyue secretly praised the underworld harm is really powerful, just by hearing a conjecture, you can find out the key to it, this intelligence, the strength of the scheming is probably only comparable to the one who has harmed him Nan Liuyue and Qin Fang's Chonghua Sect Young Master Gu Luohua, not only in his heart but also a little more careful about the underworld.

The underworld obviously didn't expect Nan Liuyue's current thoughts, and continued: "This kind of demon insect, I'm afraid it can only be called out according to its preference, but if this thing opens up the spiritual intelligence, I'm afraid it will be difficult to work." ”

"If Daoist friends guess correctly, I can be sure that the refining worm has no spiritual intelligence. Nan Liuyue said after thinking about it.

"Oh, why are you so sure?" said the Stygian Evil.

"If this thing is born with spiritual intelligence, then this trace of blood mist should have died, and it will never be so active, after all, the demon insect should be able to sense that the Taoist friend has captured a part of itself, and it will inevitably reveal its true body, and it should give up this insignificant trace of crimson. Nan Liuyue explained.

"Not bad~!Daoist friend is right~!It should be like this~!" Hades said suddenly.
