Li Muran suspended the cultivation of the "Taixu Sutra" exercises, and he wanted to help Xiao Lei advance with all his strength first.

Li Muran floated into the air, took out a talisman, stretched out his fingers, and the latter turned into a white light and disappeared into the void.

The next moment, a rune array of tens of zhang in size appeared in the nearby void, and a spiritual power vortex was formed in the center of this rune array, which swept the surrounding heaven and earth vitality into it.

The rune array only attracts the aura, while the demonic energy is excluded. Xiao Lei is a spirit bird, and it needs a large amount of pure spiritual energy to advance, not demonic energy.

Gradually, a cloud of multicolored spirits appeared in the sky. Moreover, in the surrounding void, there were thunderbolts that continued to shoot out, submerging into the spiritual clouds. This is the power of heaven and earth thunder and lightning inspired by Xiao Lei, not the clouds. This special spiritual cloud full of thunder and lightning power is the key to Xiao Lei's advancement.

If a Terran monk hits the bottleneck of the exercises, he will close his eyes and meditate at this time, turning the spiritual clouds into a stream of spiritual light and introducing it into his body to absorb and refine. But Xiao Lei was different, it took the initiative to rush into the spirit cloud, wantonly swallowing the pure vitality contained in the spirit cloud.

The spirit cloud is getting bigger and stronger, and Xiao Lei's body is hidden in the spirit cloud, shuttling and swimming. Thunderbolts struck the spirit cloud from the nearby void, replenishing the power of the spirit cloud's thunder and lightning.

This scene is spectacular, and you can feel it from afar. The powerful spiritual pressure generated by the spirit cloud, as well as the rumbling thunder, had already scared away the demon beasts and demonic beasts within a hundred and ten miles nearby.

Li Muran didn't dare to be careless, this advanced celestial phenomenon was too conspicuous, it could indeed scare away low-level demon beasts, and in turn, it might also attract some high-level demon beasts.

Sure enough, half an hour later, a two-headed demon winged dragon with a body size of a hundred feet flew here, like a huge black shadow shrouded in the sky above the dense forest.

This magic winged dragon had two heads, one cold and one hot. One head breathed a very cold breath, and the other spewed flames in its mouth.

Ice and fire are two diametrically opposed attributes, but this two-headed pterodactyl actually has two heads, one ice and one fire, and its cultivation is also extremely high.

"Demonic beasts of the Spirit Body Stage!" Li Muran frowned slightly. This kind of monster belongs to the demon realm, and it should not exist in the spirit realm at all. However, it is not surprising that this sealed space is a huge demon land, and it also has high-level spirit beasts and demonic beasts.

This ice and fire two-headed pterosaur obviously also noticed Li Muran's existence, but it obviously didn't take Li Muran in its eyes, just glanced at it, and directly rushed towards the little thunder in the spirit cloud.

Xiao Lei's body is also very huge, but compared to this two-headed pterodactyl, it looks insignificant.

The body of the two-headed pterosaur is covered with a thick layer of hard scales, like a layer of solid armor, making its body extremely strong. Wherever it flew, there were bursts of thunder, and a lot of thunder and lightning struck its body, but it didn't care at all, and continued to rush towards Xiao Lei.

Li Muran's brows furrowed, he sacrificed the greedy sword, and then his figure flashed, and a teleportation technique suddenly blocked in front of the two-headed pterodactyl.

The two-headed pterosaur immediately opened its mouth and spewed out at the same time, and an extremely cold aura surged forward like an icicle, freezing the ice hundreds of zhang in front of it in an instant, and at the same time, there was a large area of raging flames, turning into a fire dragon and pounced on Li Muran.

The two spells of ice and flame not only do not conflict, but cooperate very tacitly.

Li Muran didn't move, the greedy sword in his hand slashed, the purple light flashed, and immediately split the surrounding ice, and his body also teleported dozens of zhang away.

At the same time, two Seven Flame Moths also flew out of his sleeves, flapping their wings one after another, creating a whirlpool of smiling spiritual power.

The vortex of spiritual power inspired by the Seven Flame Moths specializes in absorbing the aura of the fire attribute. In an instant, the flames spit out by the two-headed pterodactyl were absorbed by the Seven Flame Moth.

Li Muran snorted coldly, although this two-headed pterosaur is connected with ice and fire, it is very rare, but as a result, the divine powers of the two attributes of ice and fire are not too powerful, and in terms of fire attribute supernatural powers, they are no match for this pair of seven-flame moths. As for his ice attribute supernatural powers, since he can cut through the ice seal with a sword, it seems that he is not very clever.

It is better to be proficient than to be proficient in all arts. In the world of cultivating immortals, there are countless magical powers of various exercises, and it is impossible to have the energy to be extremely proficient in each of them. If you know a little bit about each of these powers, you will still end up being obscure to everyone, but on the contrary, you only need to master one of them to stand out from the crowd.

Although he only fought one move, Li Muran could see that the strength of this two-headed pterosaur was average. Although it has a high level of cultivation, hard leather armor, strong defense, and a difficult sword to damage, it is not difficult to deal with.

Li Muran stretched out his fingers, and a flash of fire sank into the void near the two-headed pterodactyl.

This flame may seem inconspicuous, but it is just a trick that is not very powerful. But after the firelight submerged into the void, seven or eight fireballs of feet in the vicinity suddenly appeared, and these fireballs burst open at the same time in an instant, making a loud noise that shook the sky.

At the same time, a huge burst of fire rose into the sky, engulfing every qiē within a radius of ten miles!

Li Muran dodged in time and watched the sky-high flames devour the two-headed pterodactyl.

He had already set up a rune array nearby, and now he had only activated a few immortal fire runes in the rune array, which must be enough to kill this two-headed pterodactyl.

The great movement of this explosion also alarmed Xiao Lei, who pierced out of the spirit cloud and watched this scene in horror.

"Don't worry, you continue to hit the bottleneck!" Li Muran relieved Xiao Lei.

Xiao Lei understood what Li Muran meant, and it let out a clear sound and burrowed back into the spirit cloud.

After a while, the fire disappeared, and although the two-headed pterosaur was not extinguished by the explosion, it was already completely devoid of breath, and its whole body was charred black.

With a big killing weapon like the Immortal Fire Talisman, you only need to hit the enemy head-on, and no matter how strong the demon beast is, the demon beast will not be able to withstand it. If other monks encounter this two-headed pterodactyl with hard leather armor, I am afraid it will be a little tricky.

Li Muran dug out two essences, one ice and one fire, from the body of the two-headed pterosaur, these two essences have opposite attributes, but they are not mutually exclusive, which is very peculiar.

"With these two essence elements, you can refine the Ice and Fire Pill, and use the power of one heat and one cold to stimulate the monk's true element mana, which can have a miraculous effect on the monk's impact on the bottleneck of the exercise. It's a pity that this is the essence of Warcraft, and it is only effective for Demon Cultivation. Li Muran said secretly in his heart.

Li Muran put Jingyuan into a jade box, and then put it in the Langhuan Cave.

The other demon beasts and demon beasts in the vicinity didn't dare to approach anymore when they saw the exploding sky-high flames from a distance.

Xiao Lei has long met the conditions for impacting the realm of the Yuan Shen Period, but he has been suppressed and cultivated by Li Muran, so his advancement is a thick accumulation, which seems to be quite smooth.

The spiritual cloud was gradually swallowed up by Xiao Lei, and Xiao Lei's body was also bigger.

A lot of silver feathers shook off its body—but before they could hit the ground, they turned into thin silver arcs of lightning and collapsed and disappeared.

At the same time, some feathers grew back on its body, and some of these feathers were densely covered with gold threads, and some were even golden feathers.

Xiao Lei's body also looks like gold and silver, which is a huge difference from before. Before the advancement, Xiao Lei only had a limited number of life golden feathers.

Li Muran was overjoyed, he knew very well that the rumored "Thor" - the golden-winged Dapeng is the golden wings that shine all over the body, Xiao Lei is now evolving in the direction of the golden wings, and the more golden feathers it has, the stronger its strength is.

Suddenly, Li Muran exclaimed, and he saw that there were seven or eight black long feathers mixed with the tail feathers of the little thunder. These black feathers actually exude a trace of demonic energy!

"What's going on?" Li Muran was stunned, these black feathers were also newly grown.

After thinking about it, he guessed that this matter was related to the special thunder spirit fruit that Xiao Lei devoured. Presumably, the pure demonic energy contained in the thunder spirit fruit could not be discharged by Xiao Lei, nor could it be refined and fused with his own true element, so he turned into several special black long feathers, hidden in some golden and silver feathers.

After Xiao Lei Shun advanced, his aura was also much stronger, and Li Muran also began to be a little worried.

Because, most likely, what will happen next is the terrible Transfiguration Tribulation. The Transfiguration Tribulation varies from demon to demon, and the power of the Thunder Tribulation encountered by different demon beasts is completely different. Xiao Lei's talent is special, and the Transformation Tribulation it encounters is likely to be several times more powerful than other demon beasts!

However, Li Muran looked up, after the spirit clouds dispersed, the surrounding sky was clear, not to mention that there were no clouds, not even a trace of strange demon wind.

Xiao Lei showed no signs of turning into a human form at all, and it circled and flew around Li Muran, as if to express his closeness and gratitude to his master.

After waiting for a long stick of incense, there was still no vision, and Li Muran couldn't help but be surprised.

"Strange! Is it any wonder that Xiao Lei hasn't transformed yet?" Li Muran muttered: "Xiao Lei's spiritual intelligence is already very high, this time the advancement of the Great Realm should be able to complete the transformation of the thing, why hasn't it transformed yet?"

"Could it be that the Thunder Spirit Fruit it swallowed was too special and delayed the transformation stage?Or is it the special law of sealing space heaven and earth here, so that the demon beasts in it can't transform smoothly?" Li Muran pondered, feeling that there were many possibilities for this matter, and he couldn't determine the real reason.

However, Xiao Lei Shun's advanced Yuan Shen period is already a fact, which makes Li Muran quite pleased. Xiao Lei's strength has soared, which is enough to become a big help for him. As for the reason, if you really can't think of it, you don't have to continue to investigate.

Li Muran gently stroked Xiao Lei's feathers, and said with a smile: "I actually let you escape a catastrophe! No, it can't be regarded as an escape, the Transfiguration Tribulation will happen sooner or later, you just delayed it by a big step." According to the classics, all the transformation of demon beasts is completed in the breakthrough of the large realm, and the breakthrough of the small realm will not undergo the transformation change. It seems that if you want to take shape, you will have to wait until one day to advance to the spiritual body. ”

"With your qualifications as the Chosen Spirit, I believe that this day will not be too far away!"
