Thunder spirit wood grows when encountering thunder. Usually, after lightning strikes, seedlings of Thunder spirit wood may grow on the ground. However, thunder tribulation often occurs and often "irrigated" by heavenly thunder, the thunder spirit wood can grow rapidly. As for the thunder spirit fruit, it not only takes more than a long time to produce the Thunder spirit fruit, but also requires a very powerful thunder tribulation often.

Li Muran discovered the thunder spirit wood and the thunder spirit fruit, and also saw the thunder cloud - this shows that thunder tribulation often appears here, and thunder will be struck by heavenly thunder soon - but he could not find the cultivator or demon who passed the tribulation.

"The thunder of the heavenly tribulation symbolizes the power of the laws of heaven and earth, and generally does not slash it out randomly for no reason. What's going on?" Li Muran was amazed.

Seeing that Xiao Lei was very interested in the special thunder fruit, he advised: "Don't worry, there will be thunder strikes down soon, so that this thunder spirit tree can absorb another batch of thunder power, and the condensed thunder fruit will be even more nourishing!"

Little Lei understood what Li Muran meant. It circled around the Lei Ling Wood and flew under two groups of catastrophe clouds.

Li Muran avoided the distance. These two groups of catastrophe clouds were rolling more and more fiercely, and there were black and white thunder arcs that kept jumping and flashing, and it seemed that they would be struck at any time. At this time, other cultivators and monsters would avoid them from afar and dare not stop the landing of the heavenly tribulation. Only the chosen spirit of the heavenly tribulation, such as Xiao Lei, dared to hover under the catastrophe clouds and welcome the arrival of the heavenly tribulation thunder!

"Boom!" In two shocking thunders, two black and white arcs of dragon-like electric dragon fell from the two groups of catastrophe clouds and slashed into the dense forest.

Suddenly, dust flew in the dense forest, and many plants and stones were instantly destroyed. The Thunder Spirit Tree was next to two thunders. Many of the thunder lightning splashed by the sky thunder were absorbed by the Thunder Spirit Tree, causing its leaves to emit a layer of Thunder Width-like light.

There are many tall trees in the dense forest. Although they are not as powerful as the thunder spirit wood, they are also quite strong, so they are not afraid of these splashing thunder arcs.

The little thunder hovered between the lightning and lightning, absorbing the power of lightning unrestrainedly, but the little thunder seemed to only absorb the white lightning, and tried to avoid the black lightning with magical energy and did not absorb and refine it at all.

These two special groups of catastrophe clouds are obviously one spirit and one demon. Unexpectedly, the power of lightning struck down is also divided into spiritual demons. The small thunder is a spiritual bird, which only refines spiritual thunder but does not absorb magic thunder. This is what Li Muran expects.

However, the heavenly tribulation had already occurred and the heavenly thunder had already struck down, but Li Muran still couldn't see the person who responded to the disaster. Could it be that the heavenly thunder was really struck down randomly?

Occasionally, the sky thunder struck randomly and it is difficult to track down, so it's fine. But a mature thunder fruit actually bears here, which means that heavenly thunder often strikes. Is the laws of heaven and earth here disordered, causing heavenly thunder to happen here?

"Boom!" When Li Muran was puzzled, the two-colored heavenly thunders struck down one after another. Not only did the little thunder happily absorb the power of the white heavenly thunder, but the thunder spirit wood below also shone with brilliant light under the bath of the heavenly thunder. The gray leaves also emitted layers of lightning light, and there were slight rays of demonic energy.

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

But when he thought about it, he had practiced the spiritual world and the demon world at the same time, and there was no conflict between them, just like this thunder spirit tree.

"So, this thunder spirit tree is also considered a dual spiritual and demon cultivator?" Li Muran smiled slightly.

Thunder sounded, and the little thunder was flying excitedly in the lightning. Every spiritual feather on its body was covered with layers of fine lightning. When Li Muran saw this scene, he couldn't help but nodded repeatedly.

"I am worthy of being the descendant of Thunder God, the pride of Thunder!" Li Muran praised. The power of heavenly thunder is not weak. If Li Muran is in it, he also needs to deal with resistance with all his strength. The small thunder not only does not need resistance, but can also absorb part of the power of heavenly thunder for his own use. This is the difference in talent.

Li Muran could not find the breath of the person who had passed the tribulation, so he simply gave up. He gradually focused on Xiao Lei - because he obviously felt that the effect of the sealing Yuan Talisman he had placed in Xiao Lei's body was rapidly weakening.

In other words, the aura of Xiao Lei is growing rapidly. The driving force of this growth makes Li Muran happy and worried.

"If this continues, I'm afraid Xiao Lei will start to advance to the Yuanshen Stage!" Li Muran said in his heart: " Should we wait and see if it changes, or should we continue to bless the Yuan sealing talisman, seal its true energy, and prevent it from advancing?"

As the master of Xiao Lei, Li Muran naturally hopes that Xiao Lei will advance smoothly. However, if Xiao Lei encounters the transformation thunder tribulation when he advances, then its thunder tribulation will be unprecedentedly powerful. Li Muran is afraid that there will be no ability to help it share one or two.

After careful consideration, Li Muran finally made up his mind: "The Taoist sect says: Tao follows nature! I have used the Fengyuan Talisman to limit its cultivation level again and again, but it is never a long-term solution. Now it has used the power of heavenly thunder to resolve the restriction of Fengyuan Talisman on its own, so let it go. If it wants to go further on the road of cultivation of immortals, it will have to face this great disaster of life and death sooner or later!"

Li Muran made up his mind that if a great disaster really came, he would help him with all his might, even if Xiao Lei could not advance, he would still save his life. Moreover, there is a special thunder spirit tree here, and a unique mature thunder spirit fruit, which can help Xiao Lei overcome the tribulation.

Not to mention when Li Muran could leave this sealed place, even after leaving, he might not have a better time to help Xiao Lei overcome the tribulation. He simply "Tao follows nature, does nothing but does everything", watch the changes, and no longer interfere.

Half an hour later, the heavenly tribulation finally ended, and the two groups of catastrophe clouds dissipated, and no longer had black and white thunder falling.

These thunders are struck by the thunder spirit trees, so although the momentum is amazing, the dense forest has not been severely damaged, and the big trees are safe and sound. Only some small trees and plants nearby are damaged. The vitality of these weeds and small trees will be tenacious. In a few years, they will grow and spread from other parts of the dense forest and cover the ground where the lightning strikes again.

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

Li Muran sensed that the thunder swallowed by the small thunder had only been refined less than one-tenth of the heavenly thunder. Although most of the heavenly thunder had been swallowed into the body, it had not been completely refined.

Before refining, the little thunder has reached the peak state in the late stage of the true body and shows signs of breakthrough. After being completely refined, it may be difficult to maintain its current state - either spit out and disperse these heavenly thunders, or hit the bottleneck, and use the power of heavenly thunder to break through to the Yuanshen 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, does not want to pursue a higher level. Xiao Lei's spiritual wisdom is no longer low, so he naturally has higher pursuits.

"Okay!" Li Muran said: "Since you are going to hit the realm of the Yuanshen Stage, then prepare more fully. This thunder spirit fruit is already ripe. Although it is a bit weird, it is a great supplement to you. If you swallow it, you will officially start to hit the Yuanshen Stage! I will set up a talisman array nearby to protect you!"

Xiao Lei understood what Li Muran meant, let out a happy and let out a clear sound, then flew to the thunder spirit wood, and swallowed the thunder spirit fruit in one bite.

Then, Xiao Lei actually put away his wings, tightened his body, curled up into a ball about a meter, and lay under the Thunder Spirit Wooden Tree. A layer of fine gold and silver lightning arcs gathered on the surface of its body, intertwined into pieces, like a thunder and lightning eggshell!

At this time, the little thunder was like a spirit egg about the size of a meter and was about to hatch, and the layer of lightning was like a layer of transparent egg shell of gold and silver.

Li Muran was not surprised. Different monks had different cultivation postures. This posture of turning into eggs in groups may be the best practice posture for Xiao Lei to prepare for breaking through the bottleneck of his martial arts.

Breaking through the bottleneck of cultivation in a great realm is definitely not a matter of a day or a night. Li Muran doesn’t take Xiao Lei to break through smoothly, maybe three or five days, maybe three or five years, or even longer.

In order to prevent other high-level monsters 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 out layers of chain talisman arrays near the dense forest. These talismans will not be activated normally, but in case of danger, they can be used instantly to give a fatal blow to the strong enemy.

"I don't know how long it will take to wait, so why not use local materials and build a wooden house with these giant trees as a temporary place to practice!" 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 cannot take the little thunder back to Langhuan Cave Heaven to practice. Li Muran must protect him here, nor can he return to Langhuan Cave Heaven, so he simply practices in this dense forest.

Li Muran stretched out his finger and bounced out a few sword lights, cutting off a few giant trees. He waved his sleeves and the broken trees stacked up layer by layer, instantly building a wooden house of several feet in size.

Li Muran photographed several green vine talismans, which turned into green vines, fixing the broken wood and becoming stronger. Soon, a simple wooden house appeared near the Thunder Spirit Wood. The wooden house had no door, and was facing the "thunder egg" transformed by the little thunder.

Li Muran flew into the wooden house, sat cross-legged, and looked at the "Thunder Egg".

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

Just under the Thunder Spirit Wooden Tree, about a foot next to the "thunder egg" transformed by the little thunder, there is an inconspicuous leafy grass.

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