This formation is very huge. Although it is just a simple rough embryo, it can be foreseen that it must be very magnificent when it is completed.

After Li Muran entered the formation, he sensed that the surrounding demonic energy became thicker and thicker. The gray and black demonic energy seemed to be thicker and thicker barriers, isolated from the spiritual magic power of fairy Ling and other spiritual cultivation, making it difficult for them to penetrate deeper.

Li Muran felt no discomfort in it, and he quickly went deep into the center of the formation - as Fairy Ling said, the construction of this formation had been terminated, and no other demon cultivators were left here.

The Demon Wolf of Xiaoyue couldn't wait to fly out of Yu Linglong, absorbing the pure demonic energy around her.

Among them, there are also strands of true demonic energy mixed in it, which is even more rare tonic.

"Time is limited, so the old man will command the demon wolf to absorb and refine the true demon energy," said the demon soul.

Then, under his guidance, the Demon Wolf of the Sharky Moon suddenly let out a long roar, and a moon-shaped magic light flew out of its mouth.

The Demon Wolf of the Sharky Moon has cultivated the Moon Eclipse Demon Body. When it exerts its magic power with all its strength, it can exert such magical powers. This round of Moon Demon Light is also transformed by its pure magic power.

The Demon Wolf of the Sharky Moon was constantly devouring the rich demonic energy around him, and the bright moon hanging above its head became brighter and brighter.

Li Muran slapped his divine palm gently, and a faint black light cover enveloped the surroundings.

This is also a black hole technique, but the black hole space sealing power formed is not too strong, just to prevent the noise here from being heard and alarming the surroundings.

The bloodthirsty demon spider was also sucking and spitting out the demonic energy, but it seemed to prefer fresh blood to eat instead of this rich demonic energy. Soon after, the bloodthirsty demon spider stopped breathing out the demonic energy around it.

The Demon Wolf of Xiaoyue was constantly sucking and spitting out the pure demonic energy around him. A bright moon above its head had turned into a huge size of more than ten feet, looking very shining. The fluctuations in its vital energy made Li Muran's face slightly change.

"I didn't expect this wolf to have cultivated to this level." Li Muran was slightly shocked. He had not summoned the Xiaoyue Demon Wolf to fight for a while, but he did not expect its strength to increase a lot.

The Demon Wolf of Xiaoyue was originally full of magic power and the surrounding demonic energy was very strong, so after half a stick of incense, the demonic energy it breathed reached saturation.

At this time, the bright moon above its head no longer expanded, but there was a gorgeous halo around the bright moon, and there was a faint dark golden light shining.

The Demon Wolf of the Sharky Moon let out a long roar, and a breeze from the wolf's mouth swept out, wrapping the bright moon and shrinking it to a size of several inches, then put it into the wolf's mouth and swallowed by it in one bite.

In an instant, the magic light shone in the body of the Xiaoyue Demon Wolf, and his aura suddenly increased a lot.

"Well, the demonic energy I breathed in this time contained some true demonic energy, which made this wolf gain a lot." Li Muran nodded with satisfaction.

He was about to take back Yu Linglong's Demon Wolf, but he was stopped by the Demon Soul.

"Let's go," the demon soul said loudly: "Look, what's unusual about the magic light emitted by this wolf?"

Li Muran was stunned and looked at the Demon Wolf of Xiaoyue. When he saw the demonic light emitted by the wolf, there seemed to be a faint dark golden halo around it.

"I haven't seen this dark golden halo before." Li Muran murmured.

"That's exactly that," said the Demon Soul excitedly: "This is a sign that the body of the Demon Wolf is about to be successful - in other words, this Wolf has found an opportunity to break through the bottleneck."

"What?" Li Muran was surprised and happy: "Is this wolf a chance to advance to the true body stage?"

Previously, the Demon Wolf of Xiaoyue was already a magic beast at the peak of level 9. If he could go further, he would be a real-body early-stage demon beast with a level comparable to Li Muran.

"It's entirely possible," said the Demon Soul: "However, you must use the special environment here and the slightest true demonic aura around you to continue to complete the advanced move."

"I'm afraid this won't work." Li Muran frowned: "There are still several true-body cultivators here. The celestial phenomena when they advance are too obvious, and they will definitely be alarmed. Moreover, the advancement of the true-body cultivator is not something that can be accomplished in a short period of time. When we advanced, it took more than half a year from the date of the birth of the celestial phenomena. Even if the wolf's advancement is very smooth, it will take at least one month to several months. Within such a long time, those true-body cultivators will definitely attack here. If they fail to advance at that time, they will harm this wolf."

"You said it right." The Demon Soul nodded: "It's true that you can't advance here."

"However, I can teach you a method to seal the pure demonic energy here, and then find a suitable place in the future, arrange a formation, and create a similar environment so that this wolf can advance," the demon soul said after pondering for a moment.

"There is such a method," Li Muran was overjoyed, "This is great."

If only a small amount of demonic energy is taken away, Li Muran can do it easily. However, it is difficult to collect and take away a large amount of pure demonic energy around him.

"There are several methods to seal a large amount of vital energy." The demon soul said: "The easiest one is to collect it with appropriate treasures. Don't you have a pair of Yin and Yang gourds? This pair of sixth-level magic weapons is a treasure that is very suitable for loading the vital energy of heaven and earth."

"However, this pair of gourds is of average quality and can absorb and accommodate limited energy. Similarly, you can also use your dantian as a container to store a large amount of heaven and earth vital energy, but the same limited capacity is far from enough.

"Actually, there is another treasure on you, which is a very exquisite space treasure that can accommodate a large amount of heaven and earth energy."

When Li Muran heard this, he was slightly stunned and said, "What I said about the Spirit Treasure Demon Refining Pot? First, there is not enough magic power to control this treasure, and second, this treasure is a spiritual treasure. I am afraid it will reject this rich demonic energy and will not suck it into it."

The demon soul shook his head and said, "What I am talking about is not the demon refining pot, but the mountain and river map you just got."

"Langyan Cave Heaven?" Li Muran was stunned again.

"Yes," said the Demon Soul: "This treasure is a real space treasure. As long as the means are skillful enough, it can accommodate mountains, rivers, and a space. Of course, it can also accommodate a large amount of heaven and earth vitality. Although you have not understood this treasure yet, I can teach you a method to temporarily seal the heaven and earth vitality here into Langyan Cave Heaven. After you comprehend this picture in the future, you can easily take it out of the picture."

"So that's it." Li Muran was overjoyed when he heard this, "Thank you for your advice for your advice"

The demon soul smiled and said, "This method is a bit complicated. Whether you can understand it in a short time depends on your own understanding."

As he said that, the Demon Soul informed Li Muran of the method of sealing the essence of heaven and earth, which was indeed very complicated.

Li Muran listened intently, then closed his eyes and meditated quietly.

Ling Xueer was waiting quietly outside the formation, feeling quite anxious.

"Friend Li has been in for two hours, why is there still no news?" Ling Xueer said to herself: "Fortunately, those demon cultivators are not in good condition to guard this place and have not sent a master of true body to investigate, otherwise they will be exposed."

"If you encounter an accident, Fellow Daoist Li should immediately notify Xueer with a notes. He didn't do that, there should be something else to delay."

"Wait for another half an hour. If Fellow Daoist Li doesn't come out yet, he will immediately use the notes to urge him to avoid long nights of dreams."

After a while, Ling Xueer was a little impatient when suddenly a loud thunder came from the center of the formation. The sound was very loud and earth-shaking. The entire huge stone hall was filled with echoes and buzzing.

With this loud noise, the rich demonic energy in the array disappeared quickly and thinly. In the blink of an eye, the demonic energy here became much weaker, only half of the previous ones.

"Oh, what happened?" Ling Xueer was shocked, "I'm afraid this will alarm the demon cultivator who is in charge nearby."

Ling Xueer hurriedly inspired the sound transmission and urged Li Muran.

Shortly after she sent out the notes, she saw a light flying from the depths of the formation. It was Li Muran.

"Go away quickly," Li Muran greeted: "I accidentally made a huge noise just now, which will probably attract the attention of the real-body magic cultivator who is in charge nearby."

Ling Xueer nodded. She knew that it was not the time to ask for details carefully, so she followed Li Muran and rushed out of the hall.

"Fly to the right, the barrier seal there is the weakest," Ling Xueer said in a voice transmission, she was quite familiar with this place.

Li Muran nodded. Ling Xueer had already had plans to sneak into the Tianhen barrier to investigate the plans of the demon forces. Of course, she also put in a lot of effort and became more familiar with the environment here.

"He Fang's Rats actually trespassed into this barrier." Suddenly, a sudden shout came from a distance, with a strong voice, and it still gathered dozens of miles away, obviously containing an extremely pure true magic power.

Li Muran was shocked. While following Ling Xueer, he flew all the way, and the divine thoughts he released also found that more than a dozen auras were chasing them from all over the place, three of which were quite powerful, and they were obviously the true body stage demon cultivators.

"It seems that a fierce battle is inevitable." Ling Xueer obviously sensed the breath of these pursuits.

She stopped somewhere, frowned slightly at several extremely fast escape lights in the distance, but there was no fear in her expression.

"Fellow Daoist Li, I'm afraid you and I will fight side by side," Ling Xueer said: "But I don't have to fight with them. I just have to hold on for a while and at the same time break the power of the nearby barrier space to escape the Tianhen barrier. As long as I leave this barrier, Xueer will have a way to quickly get rid of the pursuit of these demon cultivators."

Li Muran felt aroused when he heard this. These words were exactly the same as what he thought.

As long as he can leave this sealed space, Li Muran can sacrifice the instant ten thousand miles talisman and easily get rid of other true body magic cultivators who are chasing behind him.
