This grass, which is only about a foot tall, looks weak and weak, but the heavenly tribulation just now was so strong that it was not destroyed, which is really strange. Although it grows under the Thunder Spirit Tree and is protected by the Thunder Spirit Tree, with its body, just a slight ray of lightning arc splashed, it should be destroyed.

The other plants and trees around the Thunder Spirit Tree have disappeared without a trace, and even the place name is charred, but this grass is still full of vitality and even a new leaf has grown, which is really incredible.

"Could this be a kind of thunder-attributed spiritual herb, so she survived the thunder?" Li Muran naturally had this idea, but after careful investigation, he could not sense any thunder-attributed aura of this spiritual herb. Besides, if this herb is a thunder-attributed spiritual herb, Xiao Lei would definitely find out and would not ignore it.

"It's not a thunder attribute spiritual herb, what kind of spiritual herb is it?" Although Li Muran is not proficient in herbal alchemy techniques, he has read many classics and can still recognize most spiritual herbs and medicines. However, he has never seen the grass in front of him and cannot recognize it.

"If it is really as I guessed, the heavenly disaster just now happened because this grass grew a new leaf, then the quality of this grass must be extremely high." Li Muran said in his heart.

According to rumors, in the process of breeding or growth of some heaven-defying treasures, they will indeed cause feedback from the laws of heaven and earth - that is, the birth of heavenly tribulation. They must be successfully overcome so that the treasures can continue to grow, otherwise they will be destroyed, transformed into the most basic energy, and return to the world.

Ordinary spiritual herbs, even the elixir of elixir, will not cause the heavenly tribulation; only some treasures with the heavenly effects that are rumored can attract the heavenly tribulation.

And this grass just grew a new leaf, which actually attracted the terrifying dual spiritual and demonic tribulation, which shocked Li Muran.

Li Muran counted carefully. In addition to the new leaf, the grass has a total of 79 leaves. If each leaf grows, it will have to go through a heavenly tribulation. Wouldn't this grass have experienced at least 79 heavenly tribulations?

Li Muran was even more shocked. Because the rare treasures mentioned in the classics only experienced one or two heavenly tribulations when they were born, and this grass actually had to experience so many heavenly tribulations, which shows that it was extraordinary.

There is only one reason - it should not be a thing in this world at all! However, it appeared here by chance, so every time it grows and every time it produces new leaves, it will bring feedback from the laws of heaven and earth and bring about disasters in heaven.

"This must be a strange treasure!" Li Muran was overjoyed. He wanted to poach the grass, but he still held it back.

"New leaves are still emerging in this grass, obviously not fully mature. It's a pity to pick them now!" Li Muran said in his heart. In the world of immortal cultivation, there are many treasures that have to be matured to have the best effect. Even if they are only a little short of being fully mature, the effect will often be greatly reduced, and even contain strange poisons.

Li Muran looked carefully and found that there were two thin buds, one big and one small, on the top of the grass. I guess these buds could grow into new leaves, which means that in time, the grass should be able to grow 81 leaves.

Eighty-one is the number of nine palaces, and it has an unusual meaning in the world of immortal cultivation. As for cultivation, eighty-one small Zhoutian is a big Zhoutian. Li Muran has reason to believe that when the eighty-one leaves are all in full, this grass should also mature.

However, Li Muran cannot estimate how long it will take to grow two more leaves. Maybe it is a few years, maybe hundreds, or thousands of years, not necessarily. After all, the living habits of different spiritual herbs are too different to predict.

However, Li Muran could recognize the year of the Thunder Spirit Wood next to the grass. The Thunder Spirit Wood has been in the year of seven or eight thousand years. If the year of the Thunder Spirit Wood is similar to the grass, then the grass should be in the year of seven or eight thousand years. In summary, one new leaf will grow in an average of about a hundred years. It will take two new leaves to grow two new leaves. This time is not long or short.

"I don't know how long I will be trapped in this sealed space, and I don't rush to dig out the grass. It's not too late to take it out before leaving." Li Muran thought of this.

Although Li Muran does not know the origin of this grass, he can first roughly determine whether it is a spiritual herb or a magic herb. The method of judgment is also very simple, which is to see if this grass absorbs spiritual or magical energy.

It is easy to say, but difficult to do. Because the process of these plants and trees absorbing the vital energy of heaven and earth is very slow and stable, almost integrated with the surrounding environment and is difficult to detect.

However, Li Muran's sensitivity to the vital energy of heaven and earth was far higher than that of the cultivators of the same level. He sat next to the grass, closed his eyes and concentrated his mind, and lucked the "No Named Skill" technique, and carefully sensed the changes in the vital energy of heaven and earth around him.

This grass has just sprouted new leaves and has just experienced the heavenly tribulation. It needs to replenish a large amount of heaven and earth vital energy, so its speed of absorbing heaven and earth vital energy is much faster than usual, which is more conducive to Li Muran's induction and identification.

"Huh!" Li Muran suddenly opened his eyes in shock. He sensed it several times and found that this grass had no choice in the vital energy of heaven and earth around him. In other words, whether it was demonic energy or spiritual energy, the grass was absorbing it.

"Is this grass actually a dual spiritual and demon cultivator?" Li Muran murmured in surprise. Judging from the dual spiritual and demonic heavenly thunder that appeared before, this statement is not without reason.

However, as both spiritual and demon cultivators, the thunder spirit wood beside the grass is half green and half gray. It is obvious that it cannot merge the two spirit and demon qi, but separate them from each other. This is just like Li Muran's original spiritual and demon cultivator, he can only use demonic energy to stimulate the magic skills and use spiritual energy to display spiritual methods. It cannot be confused.

However, this grass is born in nature and there is no limit to the distinction between spiritual and demons on the surface. Li Muran couldn't help but wonder, could this grass be able to merge the two spirits of spiritual and demons?

If this is true, it is definitely a treasure that goes against the sky! No wonder it has to go through the heavenly disasters again and again during its growth!

Li Muran was moved by his heart. The two spirits of the spirit and demon have always repelled each other. Even the Mahayana masters in the spiritual world cannot merge these two heaven and earth vitality. If this grass has the magical effect of fusion of the two spirits of the spirit and demons, it will definitely be of great use.

Li Muran took out a stack of talismans and laid layers of hidden talisman arrays around the grass, making it difficult for nearby monsters to discover this grass.

He had made up his mind to practice here for a while, on the one hand, he helped the little thunder to impact the bottleneck of the Yuanshen period, and on the other hand, he had to wait quietly for the grass to mature.

Previously, Li Muran absorbed a large amount of sword energy and divine thought power sealed by Master Xuanguang, and his cultivation had reached the peak of the middle stage of the Yuanshen. At the same time, his divine consciousness increased a little. There was also the ten thousand-year ice soul obtained from Ye Shuang, the fantasy realm of the Evil Spirit Valley, which was also a great supplement for practicing divine thoughts. However, Li Muran has never been willing to completely refine this treasure because his divine thought skills have been practiced to the extreme. Even if he refines the ten thousand-year ice soul, the effect will not be too significant.

Now that he has obtained the last three levels of the "Taixu Sutra", there is a lot of room for improvement in his spiritual consciousness. After careful consideration, Li Muran decided not to hit the bottleneck of the exercises for the time being, but to practice the fourth level of the "Taixu Sutra".

The stronger the spiritual consciousness, the easier it will be to break through the bottleneck. Moreover, the conditions for him to practice the "Taixu Sutra" have already come naturally, but he cannot practice because he has not had any skills.

Li Muran carefully sorted out the "Taixu Sutra" exercises in his divine thoughts, and recited the fourth level of mantra three times from beginning to end, carefully pondering them.

It took him half a month to basically understand the theme of the fourth level of the "Taixu Sutra" before he began to practice.

The divine thought turned into wisps of clear spring, wandering inside Li Muran's body. However, Li Muran had just used a small Zhoutian according to the fourth level of exercises, and suddenly his face changed and he looked up.

I saw a ball of spiritual clouds gathered over the dense forest, and the spiritual clouds rolled constantly, which was a sign of disaster clouds!

"Oh no, I encountered the heavenly tribulation again!" Li Muran said with a wry smile. This is not the heavenly tribulation of the mysterious grass, but the heavenly tribulation brought by himself.

He once encountered a heavenly tribulation when he practiced the Hinayana in the first level of the Taixu Sutra. Because the Taixu Sutra is a bit too powerful for the cultivators in the lower realm, it caused the heavenly tribulation.

Unexpectedly, when he was in the spiritual world, he had just started practicing the fourth level of martial arts, and there was a heavenly tribulation. From this point of view, in the spiritual world, the "Taixu Sutra" is also an extremely powerful heaven-defying technique!

The little thunder that had originally turned into a thunder egg and remained motionless, sensed that the master was about to have a catastrophe, and it broke out and flew out. It spread its wings and flew directly into the calamity cloud.

"Boom!" A golden thunder struck down and was falling on Li Muran's head.

Li Muran was prepared for a long time. The golden jade clothes on his body instantly inspired countless gorgeous runes, which piled up on him layer by layer, protecting his whole body.

At the same time, Li Muran even turned his divine mind into a shield, forming a shield transformed by a phantom in an instant, blocking it under the golden thunder.

"Bang!" Jin Lei directly penetrated layers of spiritual runes and smashed these runes. Then, Jin Lei smashed the Phantom Shield and then fell on Li Muran.

Li Muran's whole body was shocked, and after a sensation of soreness and pain, he relied on his powerful body to dissolve the remaining power of the golden thunder.

Although this heavenly thunder is powerful, fortunately there is only one. The catastrophe cloud dissipates, and the small thunder flies out of the catastrophe cloud.

Li Muran has extraordinary means and has the help of Xiao Lei, so resisting this golden thunder is no problem!

The little thunder also absorbed a lot of the power of heavenly thunder, and its aura became even more violent.

"Xiao Lei is finally about to officially start advancement!" Li Muran thought.
Chapter completed!
