Thunder spirit wood is born when it encounters thunder, usually after a lightning strike, the ground may breed the seedlings of thunder spirit wood. However, it is necessary to have frequent thunderstorms and often receive "irrigation" from heavenly thunder so that the thunder spirit wood can grow rapidly. As for the Thunder Spirit Fruit, it would not only take more than thousands of years to produce it, but it would also have to be a very powerful Thunder Tribulation from time to time.

Li Muran discovered the Thunder Spirit Wood and the Thunder Spirit Fruit, and also saw the Tribulation Cloud—which showed that there were indeed thunder tribulations here, and there was about to be a heavenly thunderbolt—but he couldn't find the monks or demons who crossed the tribulation at all.

"The thunder of the Heavenly Tribulation, symbolizing the power of the laws of heaven and earth, generally does not slash down indiscriminately for no reason, what is going on?" Li Muran was surprised.

He saw that Xiao Lei was very interested in that special thunder spirit fruit, so he persuaded: "Don't worry, there will be a heavenly thunder split down soon, let this thunder spirit wood absorb a batch of heavenly thunder power, and the condensed thunder spirit fruit will also be more replenished!"

Xiao Lei understood what Li Muran meant, and after circling around the Lei Lingmu for a while, it flew below the two clouds of tribulation.

Li Muran avoided it from a distance. These two clouds of calamity are rolling more and more intensely, and there are two kinds of black and white thunder arcs constantly jumping and flashing, and it seems that they are about to split down at any time. At this time, the other monks and demon beasts would stay away, not daring to stop the Heavenly Tribulation from descending. Only the Chosen Spirit of the Thunder Attribute like Xiao Lei dared to hover under the clouds to welcome the arrival of the Thunder of the Tribulation!

"Boom!" In the two earth-shattering thunderbolts, two dragon-like arcs, one black and one white, fell from the two clouds and split into the dense forest.

Suddenly, the dust in the dense forest was flying, and many plants, trees and stones were instantly wiped out. That thunder spirit tree was next to the two heavenly thunders. Many of the thousands of wisps of thunder splashed by the heavenly thunder were absorbed by the thunder spirit wood, making its leaves glow with a layer of thunder-like light.

There are also many tall trees in the dense forest, although they are not as capable of absorbing the power of heavenly thunder as the Thunder Spirit Wood, they are also quite strong, and they are not afraid of these splashed thunder arcs.

Xiao Lei hovered between the thunder and lightning, absorbing the power of thunder and lightning recklessly, but - Xiao Lei seemed to only absorb the white thunder light, and for the demonic black thunder and lightning, he tried to avoid it, and did not absorb and refine it at all.

These two special clouds of calamity are obviously one spirit and one demon, and the power of thunder and lightning under the chop is also divided into spirit demons, Xiao Lei is a spirit bird, only refining spirit thunder, not absorbing demon thunder, which is expected by Li Muran.

But the catastrophe has happened, the thunder has been split, but Li Muran still can't see the person who should be robbed, is this thunder really hacked indiscriminately?

Occasionally, the sky thunders and splits, and it is difficult to trace the reason, so that's it. However, there is a ripe thunder spirit fruit here, which means that there are often thunderbolts from the sky. Could it be that the laws of heaven and earth here are disordered, and the heavenly thunder always happens here?

"Boom!" When Li Muran was puzzled, the two-color sky thunder slashed down one after another. Not only was Xiao Lei happily absorbing the power of the white heavenly thunder, but the thunder spirit wood below was also bathed in the heavenly thunder, glowing with brilliant light. The gray leaves also glowed with layers of thunder, and there were faint wisps of demonic energy emitting from them.

"It turns out that this Thunder Spirit Tree is not half dead and half alive, but half spirit and half demon, it's really weird!" Li Muran was quite curious.

However, after thinking about it, he himself had cultivated the Spirit Realm and the Demon Realm exercises at the same time, and they did not conflict with each other, just like this Thunder Spirit Tree.

"In this way, this Thunder Spirit Tree can also be regarded as a dual cultivation of spirit and demon?" Li Muran smiled slightly.

There were bursts of thunder, Xiao Lei was flying excitedly in the thunder and lightning, and every spirit feather on its body was wrapped in layers of fine thunder light, Li Muran couldn't help but nod again and again when he saw this scene.

"It is worthy of being the queen of Thor, the proud son of thunder!" Li Muran praised. The power of thunder is not weak on this day, and if Li Muran is in the middle of it, he also needs to deal with resistance with all his might. And Xiao Lei not only does not need to resist, but can also absorb part of the power of heavenly thunder for his own use, this is the difference in talent.

Li Muran couldn't find the breath of the person who crossed the robbery, so he simply gave up, and gradually focused his attention on Xiao Lei - because he obviously felt that the effect of the sealing talisman he had set in Xiao Lei's body was rapidly weakening.

In other words, Xiao Lei's aura is growing rapidly. Driven by this growth, Li Muran was both happy and worried.

"If it goes on like this, I'm afraid that Xiao Lei is going to start advancing to the Yuan Shen Stage!" Li Muran secretly said in his heart: "Should we wait and see what happens, or should we continue to bless the Sealing Yuan Fu, seal its true yuan, and not let it advance?"

As the owner of Xiao Lei, Li Muran naturally hopes that Xiao Lei will advance smoothly, but in case Xiao Lei encounters the Transformation Thunder Tribulation when he advances, then its Thunder Tribulation will be unprecedentedly powerful, and Li Muran is afraid that he will not have much ability to help it share one or two.

After thinking about it carefully, Li Muran finally made up his mind: "The Dao Gate has clouds: the Dao Law is natural! I have used the Feng Yuan Fu three times to limit its cultivation, but it is never a long-term plan. Now that it has used the power of the heavenly thunder to resolve the restrictions of the Fengyuan Fu on its own, it will simply let it be. If it wants to go further on the path of cultivating immortals, sooner or later it will have to face this catastrophe of life and death!"

Li Muran made up his mind that if a catastrophe really came, he would do his best to help, even if Xiao Lei couldn't advance, he would save his life. Moreover, there is also a special thunder spirit tree here, and there is a unique ripe thunder spirit fruit, which can help Xiao Lei cross the tribulation.

Not to mention when Li Muran will be able to leave this sealed place, even after leaving, he may not have a better time to help Xiao Lei cross the catastrophe, so he simply "does nothing but does nothing", waits and waits for changes, and no longer interferes.

Half an hour later, the tribulation finally ended, the two clouds of tribulation dissipated, and no more black and white thunderbolts fell.

These days, the thunder is all slashed next to the thunder spirit wood, so although the momentum is amazing, the dense forest has not been damaged by much strictness, and those big trees are safe and sound. Only a few small trees and grass trees in the vicinity were damaged. These weedy trees are so vigorous that within a few years they will grow and spread from other parts of the forest, recovering the ground where the lightning strikes.

At this time, Xiao Lei's breath had become quite violent, and it continued to hover in the sky, digesting the power of thunder and lightning in its body.

Li Muran sensed that the heavenly thunder that Xiao Lei swallowed was only refined less than one-tenth, and most of the heavenly thunder, although it was swallowed into the body, it had not been completely refined.

Before refining, Xiao Lei has already reached the peak state of the late stage of the true body, and there are signs of breakthroughs, after complete refining, I am afraid it will be difficult to maintain the current realm - either spit out and disperse these heavenly thunders, or impact the bottleneck, with the help of the power of heavenly thunder to break through to the Yuan Shen stage in one fell swoop!

Xiao Lei's choice was obviously the latter, because it had no intention of spitting out the unrefined Heavenly Thunder in his body at this time.

Li Muran nodded, he understood Xiao Lei's intentions. Any immortal cultivator, whether human or demon, who doesn't want to pursue a higher realm. Xiao Lei Lingzhi is not low, and naturally has a higher pursuit.

"Okay!" Li Muran said, "Since you are going to impact the realm of the Yuan Shen Stage, then be more prepared. This Thunder Spirit Fruit is ripe, and although it is a little weird, it is a great complement for you. You swallow it, and officially start to impact the Yuan Shen Stage! I will set up a talisman array nearby to protect the Dharma for you!"

Xiao Lei understood what Li Muran meant, let out a loud cry of joy, and then flew to the vicinity of the thunder spirit wood and swallowed the thunder spirit fruit in one gulp.

Immediately, Xiao Lei unexpectedly put away his wings, tightened his body, curled up into a ball the size of a zhang, and lay under the Lei Lingmu tree. A layer of fine gold and silver thunder arcs gathered on the surface of its body, intertwined into pieces, like a thunderbolt eggshell!

At this time, Xiao Lei was like a spirit egg about to hatch the size of a zhang, and that layer of thunder light was like a transparent eggshell of gold and silver.

Li Muran was not surprised, different monks have different cultivation postures, and this posture of turning eggs into a group may be the best practice posture for Xiao Lei to be ready to break through the bottleneck of the exercises.

Breaking through the cultivation bottleneck of the Great Realm is by no means an overnight thing. Li Muran didn't know how long it would take for Xiao Lei to break through, maybe three or five days, maybe three or five years, or even longer.

In order to prevent other high-level demon beasts from coming here to disturb Xiao Lei's cultivation, Li Muran took out a thick stack of high-level talismans from his sleeve and laid down layer after layer of chain rune arrays near the dense forest. These talismans are not usually activated, but in case of danger, they can be cast in an instant to deal a fatal blow to a strong enemy.

"I don't know how long I'll have to wait, so it's better to use local materials and build a wooden house with these giant trees as a temporary cultivation place!" Li Muran said to himself.

To break through the great realm, you need to communicate the power of the laws of heaven and earth, so you can't take Xiao Lei back to the Langhuan Cave Heaven to practice. Li Muran wanted to guard here, and he couldn't return to Langhuan Cave Heaven, so he simply practiced in this dense forest.

Li Muran stretched out his fingers and popped out a few sword lights, cutting off a few giant trees, and with a light wave of his sleeve robe, those broken trees were stacked on top of each other, and they were built into a wooden house several zhang in an instant.

Li Muran shot out a few more green vine talismans, and these talismans turned into green vines, fixing the broken wood and becoming stronger. Soon, a simple wooden house appeared near the thunder spirit wood. There is no door in the wooden house, and it is facing the "thunder egg" that Xiao Lei has turned into.

Li Muran flew to the wooden house, sat cross-legged, and looked at the "thunder egg".

He was about to close his eyes and start practicing, when suddenly his face changed, and his gaze was firmly attracted by something.

Just under the Lei Ling Wood tree, next to the "Thunder Egg" transformed by Xiao Lei, there is an inconspicuous leafy grass.

The leaves of this grass are heart-shaped, and there is another leaf at the top that is smaller and significantly more tender in color, apparently a new leaf.

"Isn't the location of this little grass exactly where the heavenly thunder struck? It wasn't actually destroyed in the heavenly thunder?" Li Muran's heart moved: "Could it be that the terrible heavenly thunder appeared just now because this grass has grown a new leaf?!"
