Daliang Mountain, thousands of miles uninhabited, inaccessible, shrouded by a piece of yellow sand. At this time, in the cave of a barren mountain in Daliang Mountain, Lei Yu was sitting in it.

The surface of his body emitted bursts of yellow light, his breathing was smooth, and waves of thunder flowed in the meridians of his body, and finally converged into the two major acupuncture points of Tianyin and Tianyang. And around him, bottles of Lei Yuan Dan were scattered around, revealing a rich aroma, turning into a wonderful formation, replenishing Lei Yu's thunder power.

This is Lei Yu's cultivation place in Daliang Mountain, which is sparsely populated and exceptionally quiet. Outside the cave, a forbidden is laid out to hide the cave perfectly. Moreover, this prohibition can also hide the fluctuations that emanate from the cave, which can be regarded as killing two birds with one stone.

"Whew...... Suck ......"

Lei Yu closed his eyes and sat on the ground, his heart was calm, and with every breath, a large amount of thunder energy would enter his body, supplying his consumption.

The thunder qi absorbed by Lei Yu is very huge, fortunately, a simple spirit gathering array is arranged around him, and there are tens of thousands of Lei Yuan Dan for Lei Yu to use, so there is no need to worry about running out of thunder qi. Under such circumstances, Lei Yu could rest assured that he could carry out his cultivation.

For this dive cultivation, Lei Yu arranged it very carefully, and almost everything was taken into account, just in case, he could successfully complete this dive cultivation and be promoted to cultivation.

"This kid's movements are quite big, it seems that this cultivation has benefited him a lot!"

On the side of the cave, an old man with black hair but an old face said with a smile: On his shoulder, there is a fluffy kitten, which looks very cute, but this "kitten" is a little strange, above its tail, there is some purple emergence, almost half of the tail is purple.

Of course, this person and a "cat" are none other than Yin Ming and the little purple jade lion. Lei Yu wanted to cultivate, and naturally Yin Yin and the purple jade lion were not good at staying in his body, so he went outside.

Hearing Yin Ming's words, the little guy "squeaked" and screamed, as if he was responding to Yin Ming's words, thinking quite cute.

"Let's cultivate on the side, this guy still doesn't know when the Dao will be?"

Yin Ming smiled slightly, sat straight to the side, closed his eyes, and sank into cultivation. And the little guy seems to understand a little, and he sits on the side and cultivates in a decent way, but this appearance is a little strange.

"Boom...... Rumble...... Boom ......"

As one person and one lion entered the cultivation, the entire cave also fell silent for a while, leaving only bursts of fluctuating sounds coming from Lei Yu's body.

This is the sound of thunder power running in Lei Yu's body, like the sound of the tide, quite extraordinary. However, Lei Yu was still immersed in cultivation, and his whole heart was as one, feeling the washing of that majestic thunder force.

Powerful thunder power poured into Lei Yu's body, the yellow light on the surface of Lei Yu became even brighter, and powerful fluctuations came out of his body, and his momentum was constantly rising, and he was about to be promoted.

Lei Yu still didn't react in the slightest to this, he seemed to be immersed in his own cultivation world, and everything had nothing to do with him. During this time, Lei Yu had experienced too much, and he had already reached the peak of the third order of the Lei Gang period, and he was only one step away from reaching the middle of the Lei Gang period.

In terms of the degree of accumulation, Lei Yu is definitely terrifying, everything is immersed in his body, just waiting for one day, these accumulations will turn into majestic thunder and rush into the sky. And undoubtedly, this diving cultivation is an opportunity.

Cultivating in order to be able to turn into a dragon once and be promoted to a higher realm!

In Lei Yu's body, a stream of thunder surged up, as if a river was rushing, and gradually merged into the Tianyang acupoint. In the blink of an eye, the Tianyang acupoint was filled with endless thunder power, endless, and quite terrifying.

If these thunder powers were ordinary cultivators, they might have broken through the shackles and reached a higher realm. It's just that all this is not very applicable to Lei Yu, he is the body of the Nine Shadows, although the natal thunder power is extremely strong, but in the same way, the thunder power required for promotion is also quite terrifying.

Although there is a lot of thunder power, it is not enough to support Lei Yu to reach a higher realm, he needs more thunder power. For this reason, Lei Yu deliberately prepared tens of thousands of Lei Yuan Dan and placed them into a simple spirit gathering array for cultivation, but now it seems that the thunder power needed to break through the shackles is still above his imagination.

Lei Yu's brows furrowed slightly, and he didn't open his eyes. He had anticipated the situation and was not surprised. The physique of the Nine Shadows Body is too difficult to break through, if it weren't for the fact that he had the 500,000 Lei Yuan Dan that was immortal, maybe he would still be worried about finding Lei Yuan Dan now.

The Nine Shadows Yellow Spring Jue was running faster and faster, and streams of thunder power poured out from Lei Yuandan, entering Lei Yu's body, and entering the Tianyang acupoint. With so much thunder entering his body, he also felt a burst of pain, and there were faint bursts of stinging pain in the meridians.

This is a manifestation that the meridians are somewhat unable to withstand the squeeze of thunder force, although his body is already equivalent to the Lei Bing of the lower grade Gang, and the meridians in his body have also reached an extremely high realm, but the thunder power generated by tens of thousands of Lei Yuan Dan is still too terrifying, and there is a vague feeling that the meridians will be squeezed.

Lei Yu gritted his teeth and insisted, this was why it was impossible for him to give up at the beginning. "Nine Shades of Yellow Spring Jue" was running, and more and more thunder power poured into the Tianyang acupoint, and a feeling of fullness jumped into Lei Yu's heart.

He had some realization in his heart that it was time to strike!

"Boom, boom, boom!"

A burst of sound came from the Tianyang acupoint, which was the fourth ** aperture that Lei Li was breaking through. With the collision of thunder forces, the Tianyang acupoint also began to loosen, and terrifying fluctuations came out, and the fourth ** aperture could be broken at any time.

The accumulation of tens of thousands of Lei Yuan Dan is not a joke, if these thunder qi suddenly penetrates into the body of a Lei Gang stage cultivator, it must not have been exploded by this thunder force long ago. Although Lei Yu is the body of the Nine Shadows, it is difficult to be promoted, but in the face of these thunder powers, the Tianyang Acupoint still can't support it for long.

After a stick of incense, there was a sound again in the Tianyang acupoint, as if it was flowing water, the fourth ** aperture opened, and Lei Yu broke through the shackles and reached the fourth order of the Lei Gang period.

Everything fell into place, and Lei Yu's impact was very smooth, and it only took less than a day to complete. All of this is related to his previous accumulation, his accumulation is too strong, coupled with the effect of those tens of thousands of Lei Yuan Dan, there is no surprise in promoting to the fourth order of the Lei Gang period.

Accumulation is thick, and it is precisely with the previous accumulation that Lei Yu was able to successfully reach the fourth order of the Lei Gang period.

"It's done!"

Yin Ming opened his eyes, there was a hint of surprise in his eyes, you must know that the further back the Dao, the greater the difficulty of breaking through, like Lei Yu, it only took less than a day to break through the fourth order of the Lei Gang Period, which is already quite commendable.

Although Yin Ming had expected all this for a long time, there was still some joy in his heart when he saw Lei Yu like this. It's just that his surprise didn't last much, and there was a trace of doubt in his heart, because he saw that Lei Yu was still with his eyes closed, not waking up, and still absorbing the majestic thunder power.

"Could it be that this kid can't break through all at once?"

Yin Ming wondered, you must know that the breakthrough of ordinary cultivators of the Dao will generally break through one order at a time, and they will definitely not act recklessly and upgrade several levels in a row, because this kind of thing is too difficult, and it can easily lead to the failure of promotion, so few cultivators will be like this.

Yin Ming originally thought that Lei Yu just wanted to be promoted to the fourth order of the Lei Gang Period, but he didn't expect Lei Yu's heart to be so big and wanted to break through to a higher realm all at once.

"Forget it, this kid, I'll escort him!"

Yin Ming muttered to himself, then closed his eyes and immersed himself in cultivation again. And for all this, Lei Yu didn't know at all, and still closed his eyes, absorbing the majestic thunder power.

Five days later, there was a sound again in the Tianyang acupoint, which was quite amazing, and then, I saw that the aura on Lei Yu's body became even more majestic, and he broke through the existing realm again and reached the fifth order of the Lei Gang period.

Five days, just five days, Lei Yu broke through again, Yin Ming's heart was a little happy, but when he saw that Lei Yu was still closed, a trace of uneasiness emerged in his heart.

Lei Yu still has no intention of giving up his cultivation, and he is not satisfied with the fifth order of the Lei Gang period, and he wants to break through to a higher realm again.

Time passed, during this time, Lei Yu has maintained a stable state, and the tens of thousands of Lei Yuan Dan have gradually dried up with the absorption of Lei Yu, and the thunder power is far less majestic than before. It's just that Lei Yu hasn't woken up during this time, and the thunder power in the Tianyang Acupoint has become more and more, and it has reached a rather amazing level, not far from reaching the sixth order of the Lei Gang Stage.

Ten days later, the fluctuations emanating from Lei Yu's body became more and more unstable, and there was a trace of pale on his face, and majestic thunder power emerged from his body. At the same time, around him, tens of thousands of Lei Yuan Dan had already reached a state of being on the verge of exhaustion.

"Are you going to start?"

Yin Ming opened his eyes, a little nervous. Breaking through three realms at once, such a thing is really amazing, and if you don't do it well, you may die. Although Yin Ming is a powerhouse in the Immortal Thunder Period, there is also a trace of nervousness.

This kind of thing can only be handled by the cultivator himself, outsiders can't help at all, although Yin Ming is anxious, there is nothing he can do, he can only let Lei Yu break through on his own.

At this moment, in the Tianyang acupoint, a majestic thunder force is surging, like a tsunami, impacting the sixth ** aperture.

A roar sounded, and the sixth ** trick rumbled, almost about to collapse.

Thunder Feather is okay, and the operation of thunder power is more impactful of the sixth ** trick, which is quite amazing. Under this impact, the sixth ** trick is also a little shaky, and it may collapse at any time.

"Boom!"

An hour later, with a loud sound, the sixth ** aperture was completely shattered, and a torrent of powerful force emerged, quickly entering Lei Yu's body. At this time, Lei Yu also opened his eyes, and his face showed a hint of joy.
