Li Muran suspended his practice of the "Taixu Sutra" technique, and he had to do his best to help Xiao Lei advance.

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

The next moment, a talisman array of dozens of feet in the vicinity appeared in the nearby void. A spiritual vortex formed in the center of this talisman array, which swept the surrounding heaven and earth energy into it.

The talisman array only attracts spiritual energy, but the demonic energy is rejected. The small thunder is a spiritual bird, and when it advances, it requires a large amount of pure spiritual energy, not demonic energy.

Gradually, a colorful spiritual cloud appeared in the sky. Moreover, there were still thunder and lightning in the surrounding void and sank into the spiritual cloud. This was the power of lightning in the heaven and earth inspired by the little thunder, not the catastrophe cloud. This special spiritual cloud filled with thunder and lightning is the key to the advancement of the little thunder.

If the human cultivator hits the bottleneck of his martial arts, he will close his eyes and meditate, turning the spiritual cloud into a series of spiritual lights and introducing it into his body to absorb and refine it. However, the small thunder is different. It actively rushed into the spiritual cloud and swallowed and sucked the pure vitality contained in the spiritual cloud.

The spiritual clouds are getting bigger and bigger, and the body of the little thunder is hidden in the spiritual clouds, swinging and moving. Thunder lightnings penetrate into the spiritual clouds from the nearby void to replenish the power of the thunder and lightning.

This scene is spectacular, and you can sense it from a distance. The powerful spiritual pressure generated by the spirit clouds and the rumbling thunder have already scared away the monsters and monsters within a hundred miles nearby.

Li Muran dared not be careless. This advanced celestial phenomenon is too conspicuous and can indeed scare away low-level monsters, and in turn may also attract some high-level monsters.

Sure enough, half an hour later, a two-headed demon-winged dragon, which was a hundred feet tall, flew here, like a huge black shadow covering the sky in the dense forest.

This demon winged dragon has two heads, one is cold and the other is hot. One head exudes an extremely cold breath, and the other is squirting a raging flame in its mouth.

Ice and fire mutual restraint are two completely opposite attributes, but this double-headed pterosaur actually has two heads, one ice and one fire, and its cultivation is also extremely high.

"The Magic Beast in the Spiritual Body Stage" Li Muran frowned slightly. This kind of monster belongs to the Demon Realm and should not exist in the Spirit Realm at all. However, this sealed space is a huge demon-ridden land, and it is not surprising that it has high-level spiritual beast monsters.

The ice and fire double-headed pterosaur obviously noticed Li Muran's existence, but it obviously did not take Li Muran seriously. It just glanced at it and rushed directly to the small thunder in the spirit cloud.

Xiao Lei's body is also very huge, but compared with this pair of pterosaurs, it seems insignificant.

The double-headed pterosaur was covered with a thick layer of hard scales, like a layer of solid armor, making its body extremely strong. Wherever it flew past, there were thunderstorms and a lot of lightning struck it, but it didn't care at all and continued to pounce on the little thunder.

Li Muran frowned, he used the Greedy Sword, then flashed, and a teleportation technique suddenly blocked the double-headed Winged Dragon.

The double-headed pterosaur immediately opened his mouth and squirted it at the same time. A stream of extremely cold air surged forward like an icicle, and instantly frozen it within hundreds of feet in front of it. At the same time, a large area of ​​raging flames turned into a fire dragon and rushed towards Li Muran.

The two magical powers of frozen and flame not only do not conflict at all, but also cooperate very well.

Li Muran remained silent. He slashed the greedy sword in his hand, and a purple light flashed, immediately splitting the ice around him, and his figure teleported dozens of feet away.

At the same time, two seven-flame moths flew out of his sleeves, flapping their wings one after another, creating a vortex of spiritual power that was smiling.

The vortex of spiritual power stimulated by the Seven Flame Moth specifically absorbs the spiritual energy of fire attributes. In a moment, the flames spit out by the two-headed winged dragon were absorbed by the Seven Flame Moth.

Li Muran snorted coldly. Although these two-headed winged dragons are very rare in ice and fire, the magical powers of both ice and fire attributes are not too powerful. In terms of fire attribute magical powers, they cannot defeat this pair of seven-flame moths. As for their ice attribute magical powers, since they can be cut open with one sword, they seem to be less wise.

It is better to be proficient than to be proficient in all kinds of techniques. In the world of immortal cultivation, there are countless magical powers, and it is impossible to have the energy to be extremely proficient in each. If you know one or two of each magical power, you will still be lost in everyone; on the contrary, you only need to be proficient in one or one, and you can stand out from everyone.

Although Li Muran could only see that this pair of winged dragons had average strength. Although it had high cultivation, hard leather armor, strong defense, and difficult to damage swords, it was not difficult to deal with.

Li Muran stretched out his finger and bounced, and a fire scattered into the void near the double-headed pterosaur.

This fire seemed inconspicuous, but it was just a magic trick that was not powerful. However, after the fire entered the void, fireballs about seven or eight feet wide suddenly popped up around. These fireballs burst at the same time in an instant, making a loud noise that shook the sky.

At the same time, a huge fire rose into the sky, swallowing everything within a radius of ten miles.

Li Muran dodged in time and watched the sky-sky fire swallow the two-headed winged dragon.

He had already set up a talisman array nearby, and now he has only activated a few immortal fire talismans in the talisman array, which is probably enough to kill this double-headed winged dragon.

The huge noise of the explosion also alarmed the little thunder. It came out of the spiritual cloud and looked at the scene in horror.

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

Little Lei understood what Li Muran meant, and with a clear sound, it crawled back into the spiritual clouds.

After a moment, the flames disappeared, and although the double-headed pterosaur was not destroyed by the ashes, it had no breath and its whole body was charred.

With a killing weapon like the Immortal Fire Talisman, you only need to hit the enemy head-on, and even the strongest monsters can't bear it. If other monks encountered this double-headed pterosaur with hard leather armor, it would probably be a bit tricky.

Li Muran dug out two essences, one ice and one fire, from the corpse of the two-headed pterosaur. These two essences have opposite attributes, but they do not repel each other, which is very strange.

"Using these two essences, you can refine ice and fire pills, and use the power of one heat and one cold to stimulate the true essence and magic power of the cultivator. This can have miraculous effect on the cultivator's impact on the bottleneck of martial arts. Unfortunately, this is the essence of the monster, and it is only effective for demon cultivators." Li Muran said in his heart.

Li Muran put the Jingyuan into a jade box and put it into Langyan Cave Heaven.

Other nearby monsters and monsters saw the explosion of fire, and did not dare to get closer.

Xiao Lei had long met the conditions to impact the realm of the Yuanshen stage, but he had been suppressed by Li Muran's cultivation; so its advancement was to accumulate strength and seemed quite smooth.

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

A lot of silver feathers shook off from it - but before these feathers landed, they turned into thin silver lightning arcs and dissipated and disappeared.

At the same time, some feathers grew again, and some of the feathers were densely covered with golden silk, and some even golden feathers all over the body.

Xiao Lei's body also looked like gold and silver, which was a huge difference compared to before. Before advancement, Xiao Lei had only a few fundamental life golden feathers.

Li Muran was overjoyed. He knew very well that the rumored "Thunder God" - the Golden-winged Roc - was the wings shining with golden light. The small thunder is now evolving towards the direction of the Golden-winged Roc. The more golden feathers it has on its body, the stronger its strength.

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

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

He thought about it and guessed that this matter was related to the special thunder spirit fruit half-spirited and half-demon swallowed by Xiao Lei. It is believed that the pure demonic energy contained in the thunder spirit fruit cannot be excreted, nor can it be refined and merged with its own true energy, so it turned into several special black feathers, hidden among some golden and silver feathers.

After Xiao Lei successfully advanced, his aura became much stronger, and Li Muran began to feel a little worried.

Because, it is likely that the terrifying heavenly tribulation of transformation is followed by monsters. The heavenly tribulation of transformation varies from monster to monster, and the power of the thunder tribulation encountered by different monsters is completely different. The small thunder has special talents, and the heavenly tribulation it encounters is likely to be several times stronger than other monsters.

However, Li Muran looked up and saw that after the spirit clouds dissipated, the sky was clear all around him. Not to mention that there was no catastrophe cloud, there was not even a trace of strange demonic wind.

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

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

"No wonder Xiao Lei hasn't transformed yet?" Li Muran murmured: "Xiao Lei's intelligence is already very high. This time, the advancement of the great realm should be able to complete the transformation. Why has it not transformed yet?"

"Is it because the thunder spirit fruit it swallowed was too special and delayed the transformation stage? Or is it the sealed space here special laws that prevent the monsters in it from transforming smoothly?" Li Muran pondered for a while, feeling that there were many possibilities in this matter, and he could not determine the real reason.

However, it is already a fact that Xiao Lei's smooth advancement to the Yuanshen period, which made Li Muran quite pleased. Xiao Lei's strength has increased sharply, which is enough to be 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 it.

Li Muran gently stroked Xiao Lei's Lingyu and smiled and said, "It's wrong to let you escape a disaster. It can't be considered a disaster. The heavenly tribulation of transformation will happen sooner or later, and you just delayed another big step. According to the classics, all the actions of monsters transforming into shapes are completed in the breakthrough of the big realm, and the breakthrough of the small realm will not undergo transformation. It seems that if you want to transform, you can only wait until one day to advance to the spiritual body stage."
