The light of the fire enveloped the monitor lizard's mountain-like head, and immediately a scorching smell came out.

After a while, the firelight dissipated, most of the monitor lizard's head was blown off, and its body was charred black, and its body lay in the main hall, motionless and breathless.

The two of them didn't spend much effort to kill the monitor lizard, and Li Muran was also relieved.

"The illusion technique is really clever, why don't you generally see you use it lightly?" Li Muran praised.

The Thousand Illusion Fairy said: "The stronger the opponent's divine thoughts, the more difficult it is to be confused by the illusion control. Therefore, this trick is quite effective when used by some low-level monks or demon beasts on the other side, but against strong enemies of the same level or even high-level, the effect is greatly reduced, and if the other party breaks the exercise, it will also receive a certain amount of backlash, so I don't dare to use it lightly. ”

"It seems that a person like me, who has a strong divine mind, is not afraid of the illusions you are waiting for!" Li Muran nodded and said.

"This may not be!" Luo Xinyuan smiled slightly and said, "Sister Phantom Glass has used illusion to control Li Daoyou unconsciously, otherwise how could Li Daoyou be so desperate for Sister Phantom Glass!"

"That's good!" said the Thousand Illusion Fairy Zhengse: "Actually, you and I are the enemies of life and death, and we are fighting fiercely, and I use illusions to lead you into the illusion, and this qiē is your illusion." ”

Li Muran was stunned for a moment, and then smiled: "If this is the case, I would rather be immersed in this illusion for the rest of my life and never wake up." ”

In addition to the fierce fighting, the three of them laughed a few words, and their hearts were relieved, and they were a little less nervous.

"I don't know if Nirvana really escaped here!" Li Muran said: "His ghost body concealment method is very clever, even if he breaks into here, most of them can not alarm the fierce beasts inside." However, there are fierce beasts here, and it is not easy for other Demon Realm monks to break in. Maybe there are some clues related to spiritual treasures!"

The Thousand Illusion Fairy nodded slightly, and said, "Yes, since I entered this Troll Valley, I have also searched a large area, and I have not found any place like the Mixed Spirit Land. This shows that the spiritual treasures found by those demon cultivators here are not bred here, but that someone left the spiritual treasures here!"

"Although the possibility that the person who left the treasure is Xuanguang and the others is very slim, it cannot be completely ruled out, so it is necessary for me and others to carefully search the Troll Valley. And this magnificent hall may have been inhabited by monks. If Xuanguang and the others really came here, maybe they would leave some clues in it. ”

Li Muran nodded again and again, the thoughts of the Thousand Illusion Fairy coincided with his. Even if it wasn't for the hunt down Nirvana, it was necessary to search this magnificent hall carefully.

The two of them cleaned up and continued to explore the depths of the main hall, they let go of their divine thoughts, and carefully searched the halls one by one.

These halls are connected to each other by corridors and passages, extending in all directions, and the construction design is very complicated.

Moreover, there are many large halls, and there are still various prohibitions, most of which have been exhausted with the passage of time, but there are still a very small number of prohibitions that still exist.

With the means of Li Muran and the Thousand Illusion Fairy, it is naturally not a problem to break these prohibitions that have greatly reduced their power. These faint forbidden existences also further proved that those demon cultivators who had entered the Troll Valley before had not broken into the depths of this hall. After all, with that monitor lizard in charge, it would be difficult for ordinary demon body mid-to-late stage demon cultivators to enter the main hall.

In addition to the monitor lizard, there are also many fierce beasts in the halls of the four places, making this hall that stretches for hundreds of miles into a big nest where the beasts gather.

Fortunately, there was no beast king with the strength of the Mahayana period, Li Muran and the Thousand Illusions Fairy were cautious, either killing them, or hiding and avoiding them directly, these fierce beasts did not cause them much trouble.

The construction of the main hall community was very complicated, and it took a lot of time for the group to fight with those fierce beasts.

Half a day later, they came to an empty hall.

It seems to be a dead end, and there is no corridor leading to the other halls in the back hall of the main hall, but there is a side door made of huge stone on each side of the main hall. Both side doors are closed, and there seems to be a forbidden blessing.

Li Muran's heart moved, he stretched out his fingers from afar, and a sword light hit one of the side doors, and sure enough, a faint layer of magic light appeared on the surface of the side door, blocking the sword light.

"Sure enough, there are prohibitions!" Li Muran said, and along the way, they have seen many similar prohibitions, and it is not enough.

Li Muran flew to the vicinity of one of the side doors, stretched out his palm and pressed it on the stone door, touching the magic light.

Suddenly, a rather powerful repulsive force appeared in the demonic light, and it shook his palm open a few feet.

"Huh!" Li Muran was shocked, with his current cultivation, it was not easy to shake his palm open!

"The prohibition here is quite powerful!" Li Muran said in surprise: "I didn't expect that after 10,000 years, the prohibition here is still so extraordinary, it seems that it must be the most important treasure land back then!"

"I'll take a look!" The Thousand Illusion Fairy flew curiously to the side door next to Li Muran, and also stretched out his hand to test the power of the prohibition.

Who knows, the palm of the Thousand Illusion Fairy actually penetrated the layer of magic light lightly, and submerged into the stone gate! It turned out that this stone gate was only a forbidden illusion, but in fact it was just a layer of prohibition, not a real stone.

"What's going on?" Li Muran was surprised.

"Strange, this prohibition is indeed extraordinary, but it has no power to repel!" The Thousand Illusion Fairy was also very surprised.

Li Muran saw that the Thousand Illusion Fairy's hands were freely probing into the magic light prohibition, and he was not harmed, so he stretched out his hand again to try.

As a result, this time it was still the same, and his palm was about to come into contact with the magic light prohibition, when it was shaken open by a strong repulsive force.

"Xinyuan, you can try it too!" Li Muran said to Luo Xinyuan.

Luo Xinyuan agreed, she reached out, and she effortlessly penetrated the prohibition.

"Why does this stone gate ban only have the power to repel me!" Li Muran frowned.

"It seems that you are not welcome here!Could it be that you have some nasty aura on you?" The Thousand Illusion Fairy smiled and took the opportunity to make fun of Li Muran.

"What the hell is going on?" Li Muran pondered.

In terms of cultivation of the Fa, he is by no means under the Thousand Illusion Fairy and Luo Xinyuan, why are these two women not excluded by the ban, but they are strongly rejected?

Speaking of which, the biggest difference between him and the second daughter is, of course, the difference between men and women!

Thinking of this, Li Muran flew to the stone gate on the other side and stretched out his hand to reach out to the stone gate.

Sure enough, another layer of magic light appeared on the stone gate, but this time, Li Muran's palm gently penetrated into the magic light, without any rejection!

"I see!" Li Muran suddenly said, he smiled: "The ban here is very interesting, it turns out to be a yin and yang ban." Male left and female right, male cultivators can only go through the side door on the left, and female cultivators can go through the side door on the right, otherwise they will be subject to a strong force of prohibition and rejection!"

"Really?" Thousand Illusion Fairy and Luo Xinyuan came to the stone gate on the left curiously, and under the temptation, they were indeed rejected by the magic light prohibition.

"What now?" the Thousand Illusion Fairy frowned slightly, "Aren't we going to act separately?"

Li Muran nodded: "I'm afraid we have to be separated temporarily! The yin and yang prohibition here is obviously artificially placed, and what is the profound meaning can only be known after investigation." Such a strange prohibition may really be a means left by Master Xuanguang and others, so it should not be missed!"

"For some reason, I always felt a little weird, and I don't know what was wrong, as if I was destined to be separated here. The Thousand Illusion Fairy said.

Li Muran said disapprerovingly: "It's just a temporary separation." Once either side finds a clue, they will immediately use the wing-like double flight technique to summon the other party back to their side. Although the prohibition here is powerful, it may not be able to stop the two of you and me! If you directly and forcibly break this yin and yang prohibition now, it will not only take a lot of effort and make a lot of movement, but it will also take a long time. In the unlikely event that a Mahayana monk also enters the Troll Valley and hears this movement, and comes here, we may be busy in vain. ”

Hearing Li Muran say this, the Thousand Illusion Fairy nodded slightly: "Okay, I'll go our separate ways." ”

Li Muran said: "The two of you enter the stone gate on the right side together, so you can take care of it." If necessary, summon the Black Flame Daoist out to protect him. ”

"Mu Ran, you are alone, you have to be more careful!" the Thousand Illusion Fairy admonished, she seemed a little worried.

"Don't worry," Li Muran smiled slightly: "Although I have a loss of true yuan, I can mobilize the vitality of the surrounding heaven and earth to cast spells, and I still have a body of divine power that I have not yet used, and there are a lot of talismans prepared, plus space means such as the Sky Devouring Charm, even if I encounter danger, I can escape to protect myself!"

As he spoke, Li Muran nodded to the Thousand Illusion Fairy and walked into the stone gate on the left.

The Thousand Illusion Fairy nodded slightly, she silently watched Li Muran disappear after disappearing into the stone gate, sighed lightly, and then said to Luo Xinyuan: "Let's go, I'll wait to see what the mystery is behind this stone gate!"

The Thousand Illusion Fairy and Luo Xinyuan immediately walked into the stone gate on the right. The hall was empty again.

As soon as Li Muran entered the stone gate, his eyes were dark, and he found himself in a dim stone cave passage.

"It turns out that the Yin and Yang Prohibition is still a small teleportation light curtain, and this should be deep underground, or in the belly of a mountain. Li Muran looked around and said to himself.

He followed the passage, apparently carved out of the rock, and in a moment came to a cave.

There are a lot of dilapidated stone seats and other utensils in the cave, and there is even a vague phantom floating in the stone cave, which seems to be meditating and cultivating.

"Nirvana!" Li Muran was surprised and delighted: "It turns out that you are hiding here!"

That phantom was the body of Nirvana's ghost, and he had been injured a lot before, and he was recovering at this time.

When Nirsheng saw Li Muran suddenly appear, he exclaimed, and immediately turned into an invisible yin wind and fled towards another channel.
