After a lot of hardships, Lei Yu finally advanced to the thunder stage, and only Lei Yu could feel the hardships. He breathed a sigh of relief, feeling a sense of relief that he had never felt before, the five-year covenant had finally been reached, and he would no longer be afraid of being kicked out of the Zixiao Sect.

A stone in his heart was put down, and Lei Yu's face was full of smiles. He ran the "Aoki Thunder Technique", and suddenly a stream of cyan thunder qi surged into his body, which was absorbed by his body, and no longer wandered around his body like before and dispersed.

He guided Aoki Thunder Qi to continue to move forward in his body, until he came to his left foot, which was where the Heavenly ** Aperture was located. At this time, a portal opened, constantly absorbing the thunder qi that poured into Lei Yu's body. It was like a huge bottomless pit, absorbing thunder and communicating with the thunder around it.

It is a natural portal that communicates inside and outside, allowing cultivators to truly control the thunder qi and form their own thunder power. At the same time, he is also an important source of strength, and almost all the thunder qi absorbed by Lei Yu is absorbed by the Heavenly ** Aperture, stored in the body, and turned into his own source of strength.

"These are the ten ** apertures surrounding the Heavenly ** Aperture, representing the tenth-order small realm of the Thunder Qi Period. "Lei Yu has been cultivating the "Aoki Thunder Jue" for three years, and at this time, the Thunder Qi Period has been successfully advanced, and the thunder technique recorded in the "Aoki Thunder Jue" is naturally known to him, and he immediately uses it.

This is an internal vision technique that allows you to see inside the body. At this moment, Lei Yu was checking the changes in the Heavenly Aperture. Not far from the surroundings of the Heavenly Aperture, a small acupoint opened, swallowing thunder gas, turning thunder into thunder power, which was a little more refined than the thunder power of the Heavenly Aperture.

Lei Yu immediately knew what this ** trick was. Cultivators have ten realms, and each realm is divided into ten levels, which correspond to the ten ** knots surrounded by the ten acupuncture points. Once these ten ** apertures are fully opened, it means that they have reached the peak of the tenth order and are about to break through, and at this time, Lei Yu only has one ** aperture that has been opened, which means that Lei Yu has reached the realm of the first order of the thunder qi period.

This realm is only the initial realm, but this also makes Lei Yu excited, after all, the body of the Nine Shadows is rare for eternity, and being able to break the shackles and break through to the Thunder Qi Stage has already created a miracle, which can be seen just by looking at the amount of thunder qi power required by Lei Yu to advance to the Thunder Qi Stage.

It took so much "Thunder Tribulation" power to make Lei Yu advance to the Thunder Qi Stage, which was unimaginable among ordinary cultivators, which also indirectly illustrated the degree of the Nine Shadows' body against the sky.

Walking against the sky, there will be extraordinary actions, and after Lei Yu broke through, he also felt that his own thunder power was full. Although he didn't know how far he had reached, he felt that he was a little stronger than an ordinary Thunder Qi Stage cultivator.

The "Thunder Tribulation" dispersed, and the "Tribulation Cloud" was still there, but it was not as violent as before, it seemed that the "Thunder Tribulation" had ended, but there was still a haze in Lei Yu's heart. In the advanced thunder qi stage, the most important thing is the help of that mysterious force, otherwise, Lei Yu may have turned into a piece of flying ashes.

That mysterious power broke away from his body after the "Thunder Tribulation" dissipated, and disappeared, and Lei Yu had no way to find out if he wanted to find out, only remembering the bone-chilling cold.

Lei Yu raised his head and looked at the "robbery clouds" in the sky. The "robbery clouds" are still there, it is gray, the black clouds are overwhelming, and the power of the sky has not yet dispersed, but it is gathering more and more, making Lei Yu, who has entered the thunder period, also feel a little uneasy.

There are nine thunder tribulations in the thunder pool, one of which is heavier than the other. Previously, Lei Yu had already survived the five "Thunder Tribulations" and did not die, and now the ninth "Thunder Tribulation" was about to fall, and I don't know what kind of scene the Dao would be.

The five-fold "Thunder Tribulation", one heavier than the other, layer upon layer, like a monstrous giant Lang, the thunder feather may overturn at any time, but this sixth "Thunder Tribulation" is the most important and the most critical. In the history of the Zixiao Sect, there are many amazing and brilliant people who want to break through the thunder pool, but they die in the ninth "thunder tribulation", you can imagine how terrible this ninth "thunder tribulation" is.

And Lei Yu's situation at this time is different, he is already in the advanced thunder qi stage, and has become a cultivator, which is different from the previous situation of a mortal, I don't know what the next sixth "thunder tribulation" of the Dao will look like.

Lei Yu had no bottom in his heart, and the "Cloud Tribulation" was silent, but the coercion was diffuse and deepened, and it could shoot straight to the bottom of his heart, so that Lei Yu had to spend some energy to deal with this coercion.

He ran the "Aoki Thunder Technique" and tried his best to practice the thunder technique in the "Aoki Thunder Technique". Fortunately, Lei Yu has been studying the "Aoki Thunder Technique" for three years in the Zixiao Sect, and he is very clear about the thunder technique in it. In a short period of time, Lei Yu had already completed the first three layers of the Aoki Thunder Jue.

Although it is only a familiarity, at least Lei Yu can have some self-preservation power in the next sixth "Thunder Tribulation".

All around his body were cyan thunder qi gathering, and the green wood thunder qi was permeated, constantly pouring into his body, supplying the thunder qi he needed for cultivation. This is the thunder pool, which gathers thunder energy within a radius of dozens of miles, which is very rich.

So much Aoki Thunder Qi entered Lei Yu's body, not only did it not make Lei Yu feel satisfied, but instead he had a feeling of hunger. Those Aoki thunder qi were all absorbed by the Heavenly ** Aperture and turned into the origin thunder power, but they were still not satisfied, and continued to absorb the surrounding thunder qi, seemingly never satisfied.

Lei Yu immersed himself in cultivation, completely ignoring everything in the outside world, even if the "Thunder Tribulation" was coming, he did not panic, and responded to all changes with the same attitude, consolidated himself, and dealt with the sixth "Thunder Tribulation".

"Boom!" "Cloud Tribulation" finally had a slight change, a thunderous sound, and a golden thunderbolt flashed out, showing the majesty of the sky. The "Cloud Tribulation" spread again, and the scope became larger and larger, gradually pressing down, dropping from the previous height of more than 100 zhang to dozens of zhang, and that gloomy aura permeated the thunder pool, and even Lei Yu, who was meditating on cultivation, felt a little uneasy.

And as time passed, the golden barrier around the thunder pool flickered again, and the dazzling golden light illuminated the thunder pool, which was in stark contrast to the "calamity clouds" above the sky. Those golden barriers were further strengthened, as if to prevent Thunder Feather from escaping.

Lei Yu sank into his own cultivation world, and the "Aoki Lei Jue" was successfully cultivated by him layer by layer, and now he has cultivated to the sixth layer, and he is only three layers away from the peak of the ninth layer. It's just that at this time, he has also reached a bottleneck, no matter how much thunder power pours in, he still can't do it.

He knew that this was not something that could only be solved by Lei Li, but also that he needed to reach a higher realm. The realm of the first order of the Thunder Qi Stage was too low, and it was impossible to cultivate the remaining three layers of the Aoki Thunder Jue. Thinking of this, Lei Yu stopped cultivating, but instead looked into the air, carefully watching the changes in the "Cloud Tribulation" Cloud Tribulation, and his eyebrows couldn't help but wrinkle.

This kind of "Cloud Tribulation" is too weird, and it is completely different from the previous "Thunder Tribulation". The power contained in "Cloud Tribulation" is not so strong, but the coercion is getting heavier and heavier, penetrating into the hearts of the people, suppressing his mind.

"Well, the power of this 'Cloud Tribulation' is constantly growing, and in a short period of time, it has more than doubled compared to the aura that was revealed before, and the amount of this power is still growing, and the speed is surprisingly fast. Lei Yu watched for a while and found something unusual.

Although there is no change in the "Cloud Robbery", the thunder power contained in the "Cloud Robbery" is showing a geometric growth trend, and it is difficult to estimate how powerful the force contained in the "Cloud Robbery" is at this time.

At this time, outside the thunder pool, flying sand and stones, the heaven and earth were filled with a powerful chaotic thunder, and all the thunder within a radius of a hundred miles were rushing into the thunder pool, which was terrifying. Some disciples who were cultivating in the Zixiao Sect were shocked by this fluctuation and stopped cultivating, a trace of uneasiness welled up in their hearts.

The higher-level elders were to appease their disciples and prevent riots, and at the same time to send people to check what was going on. There was a panic within the Zixiao Sect, shocked by Lei Chi's movements.

"Hey, this seems to have come from the direction of the Thunder Pool, the power is so strong, is there any disciple who can't enter the Thunder Pool to cultivate?" Zixiao Sect, in a hall, an old man wearing a Taoist robe, immortal wind Dao bones, sitting cross-legged on the **, looking in the direction of the Thunder Pool, with a thoughtful look on his face, this is the old man who explored the Thunder Pool today.

He couldn't help but think of everything he had seen in Lei Chi today. A young man broke into the thunder pool as a mortal, and that kind of perseverance lingered in his heart. It's just that this fluctuation of strength makes him feel a little hesitant, is it really that young man?

The old man's heart was full of doubts, but after a while, the old man regained his composure and said slowly: "Don't panic, the elders will go to the Thunder Pool with this seat to check." The voice was not loud, but it was full of a majesty, and it spread through the temple.

"Obey the orders of the Great Elder!" Suddenly, a loud voice sounded from all directions. At the same time, streamers of various colors flew out from all over the Zixiao Sect and surged towards the direction of the Thunder Pool.

And in a valley more than 100 miles away from the Zixiao Sect, a very handsome young man in a white robe looked in the direction of the Zixiao Sect, a trace of solemnity flashed in his eyes, and he didn't know what Lu Dao was thinking.

At the same time, in the same valley, a woman who looked like a fairy was also looking into the distance, her beautiful eyes flashing, and between the turns, some curiosity flashed from her eyes.

The power contained in the "Cloud Tribulation" became more and more powerful, making Lei Yu's heart more and more frightened. If this strength continues to gather, I'm afraid he really won't have the slightest strength to fight back. It's just that at this time, Lei Chi was covered by a layer of light curtain, and he couldn't pass through it at all, so he could only pass through this level head-on.

Time seems to stand still, and the heavens and the earth are silent, but the power of the sky does not disperse, and it becomes more and more turbulent. The ninth "Thunder Tribulation" is still the beginning, but it has already taken the lead, which is terrifying.

Lei Yu carefully looked at the changes in the "Cloud Tribulation", and I don't know when the "Cloud Tribulation" had undergone some changes from the previous black, and was gradually covered by some purple. As time passed, the purple color became more and more, and in a short period of time, it spread to the entire "Cloud Tribulation".

The weird purple, the frightening sixth "Thunder Tribulation", everything is frightening. Lei Yu's heart turned up in the monstrous Lang, and he muttered to himself: "Is this the sixth 'Thunder Tribulation'?" his hands clenched, and a layer of cold sweat broke out, but he didn't know it at all.
