Xuan Lei advanced extreme thunder, will produce a certain amount of power leakage, but not too strong, but once the extreme thunder to the Holy Thunder advanced, it can cause a side of the heaven and earth to shake, because where the power is formed, it will inevitably release about one-tenth of the power to spread outward, at that time, it is often the moment when all masters dare not approach, once released, the power is so strong, I dare not imagine, unless it is in the water god vein, the thunder god vein and other cultivation supreme divine land, it will not be released, but will be absorbed by other extreme powers.

Xie Aoyu was deep in the Hell Demon Realm, and it was even more in a no-man's land, so it was naturally impossible not to leak out, so he avoided the Silent City from afar, a distance of nearly three hundred miles.

Only then did he cultivate with peace of mind.

At a distance of thousands of meters underground, Xie Aoyu's whole person has entered an ethereal state, no one and no self, his whole person seems to have become a wood carving clay sculpture, everything has stopped, only the dantian is undergoing transformation.

There is a small spot of light in the center of the white thunder and lightning power, which constantly emits a circle of light, washing the thunder and lightning power.

That small point of light was formed after the fusion of the power of the heaven and earth god thunder, and it was baptizing the power of thunder and lightning, making it constantly transform, advancing towards the thunder of the demigods.

Xie Aoyu seemed to have forgotten everything, and the whole person was immersed in it.

Three days passed in the blink of an eye.

This secluded valley also ushered in a change, and at noon, when the sun was blazing, suddenly dark clouds surged in all directions.

No one knew how these black clouds appeared, and all of a sudden, they had covered a sky, turning the valley into a dark world for thousands of miles, with no light to be seen, and no fingers to be seen.

Naturally, Silent City also has a considerable number of locations in it.

For a time, the clouds moved in all directions.

Almost all the forces and all the masters stopped what they were doing, and flew into the air one after another, looking at the location of the valley where Xie Aoyu was located.

A trace of electric light appeared out of thin air.

Countless electric lights appeared around the valley, each as thin as a gossamer, and if anyone saw it, they would be absolutely horrified, because they were all extreme thunder.

So many extreme thunders are densely packed, like fish floating on the surface of the valley in the water, and fluctuating with very terrifying power, these extreme thunders can all inspire the strongest power, and the power is not something that the immortal realm can fight against, even if it is Feng Zhaokang and other masters of the immortal realm, they can only stimulate the power of four or five percent of the ultimate power, and all of them can be stimulated, which is enough to make the Tongtian-level retreat and flee.

When the extreme thunder light reached a certain number, it began to operate regularly, with Xie Aoyu's vertical direction as the center, each extreme thunder light slowly rotated around, gradually, connected to each other, forming a huge thunder and lightning pillar, and crossed the mountain, towards the sky.

Even people hundreds of miles away can see that a thunderbolt is connected to heaven and earth, hundreds of miles away, the power of thunder and lightning makes the soul of the immortal realm master tremble, and no one dares to approach forward.

In the City of Annihilation, Ice Dance and Ruyan looked at each other expectantly.

They naturally knew that it was the vision of heaven and earth produced by Xie Aoyu's thunder and lightning power advancement, and the two women looked at it a little nervously, whether they succeeded or not, the meaning was very different.

Xie Aoyu, who was thousands of meters underground, was still isolated from everything in the outside world, as if his mind was silent.

He didn't have a mind.

Don't interfere, just create the best environment to give the lightning power to the next level.

At this moment, the halo emitted by the center of the thunder and lightning force is becoming less and less, but the entire thunder and lightning power has turned pure white, without a trace of impurities.

Another three days passed.

The space ring on the tip of Xie Aoyu's finger trembled slightly, and the thunderbolt heart crystal ball flew out.

"Smack!"

The crystal ball shatters automatically.

The heart of thunder and lightning inside also suddenly spread out, turning into a thunder and lightning mask, enveloping Xie Aoyu entirely, and the thunder and lightning mask had a lot of thunder and lightning rays connected with the thunder and lightning power in the dantian.

Then Xie Aoyu's body slowly rose out of the ground, all this, Xie Aoyu himself did not know, his mind had already fallen silent, it seemed to be integrated with heaven and earth, and there was a communication with heaven and earth, in the sense of Tianwei's soul, and the mystery of the heart's eyes.

Leaving the ground, Xie Aoyu sat cross-legged and ascended from the center of the thunder and lightning, reaching mid-air.

"Boom, boom, boom......"

The roar continued.

Above the sky, thunder roared, and countless thunderbolts were generated, quickly converging from all directions, intertwining with the center of the thunder and lightning pillar.

As a result, countless thunderbolts began to condense rapidly.

Even this huge pillar of lightning condensed by extreme thunder began to gather inside.

Gradually, a huge ball of lightning began to take shape.

"Strange, why didn't that shattered soul forbidden power appear? even if it was already shattered and would collapse in a short time, but with such a power, it had already surpassed the power of the immortal realm, why didn't you draw it down?" Feng Wuying looked at the thunder and lightning power, very puzzled.

Feng Zhaokang said lightly: "It's not that it didn't appear, but the soul prohibition in that place has been shattered by that power before it even appears." ”

"How is that possible!" said Feng Wuying, shocked.

"Nothing is impossible, the power of thunder and lightning should have surpassed the Tongtian level. Feng Zhaokang said, "Fortunately, that power has not spread, otherwise, I am afraid that the soul prohibition of the entire Hell Demon Realm will be destroyed in one fell swoop." ”

"Beyond the power of the Tongtian level, that is not the power beyond the giants, is it the power of the Holy Thunder?" said Feng Wuying.

Feng Zhaokang muttered, "I'm not sure either. ”

How difficult it is to form the power of the Holy Thunder, even in the God Realm and the Hell Demon Realm, it is very rare, and few people have seen it.

Two days passed.

The thunder and lightning power gathered from all directions of the Hell Demon Realm had reached an indescribable level, and the thunder and lightning pillars composed of extreme thunder light had also been completely integrated into it, forming a huge thunderball with a diameter of about 100 meters.

The moment this thunderball was formed, all the hellish demonic qi within a radius of thousands of miles was transformed into thunder attributes, and a huge thunder and lightning condensed divine dragon with a length of 10,000 meters appeared in the sky, and the whole world seemed to have entered the countdown to the end of the world, and all the masters of coercion did not dare to act rashly.

Xie Aoyu, who was floating in the air, also slowly merged into the huge thunderball.

As soon as you enter it, the power within the dantian can tremble.

The hundred-meter-long thunderball began to dissolve rapidly, and its essence was integrated into the thunder and lightning power, so that the thunder and lightning power underwent a final baptism.

With the increase in the amount of thunder and electricity, Xie Aoyu's mind finally recovered.

He opened his eyes.

It was also at the moment when his eyes opened, the thunder and lightning power stopped absorbing the power of the thunder and lightning light ball, and it just happened to complete the advancement, achieving the thunder of the demigods, giving people a mysterious and mysterious feeling.

"Crackle!"

The snow-white demigod thunder trembled slightly, but it was only a trembling.

The ball of thunder and lightning that had not yet been completely absorbed suddenly burst open, and above the void, countless thunder and lightning dragons also trembled.

"Boom, boom, boom......"

For a moment, the sky fell apart.

Within a radius of 100,000 miles, countless cracks appeared in the sky, just like the collapse of the Hell Demon Realm, and the so-called messy soul prohibition was also completely shattered, and it no longer worked, and in these 100,000 miles, the ground was not devastated, and there was no city collapse, but all the masters, even the Tongtian-level powerhouses, also landed one after another, and no one dared to fly in the air.

It took three minutes for such a massive upheaval to end.

The terrifying power was devastating.

Xie Aoyu was also shocked when he saw this power, it was just a faint turmoil of the demigod thunder, if it was described as a person's power, it was like a person sneezing, it could actually make a world almost collapse, if it exerted one-tenth of the power, wouldn't it also be able to destroy the lower demon realm?

With this demigod thunder, as long as his own strength is enough, he can exert two or three percent of his power, which is enough to kill ordinary giants in seconds, and exert half of his power, even if it is an ancient psychic divine tree, the giants of the angel clan can also be killed in seconds, and it is really done, to the point of sweeping everything.

The thunder of the demigods in his hand increased Xie Aoyu's confidence.

He fell down lightly and stood at the foot of a mountain three thousand meters high.

Looking up at the high mountain, Xie Aoyu's heart was stirring, and he wanted to try to see how much power he could exert with the thunder of the demigods.

One percent of the power of the demigod thunder is estimated to be feared by ordinary Tongtian-level masters, so Xie Aoyu doesn't expect to be able to do this, he only has one thought, that is, to be able to exert one-thousandth of the power of the demigod thunder, which is also very good.

Taking a deep breath, Xie Aoyu's whole body crackled.

The demigod thunder in the dantian trembled slightly, and a touch of snow-white electric light emanated from the demigod thunder, and there was no need to urge the combat power, Xie Aoyu pointed at it casually.

"Whew!"

Snow-white electric light shot out from the tips of his fingers.

There were no monstrous power fluctuations, only a faint flash of light.

The snow-white lightning disappeared into the three-thousand-meter-high mountain.

Xie Aoyu closed his eyes and felt with his heart that he had to use the power of this blow to see how much power he could exert the demigod thunder.

"Boom ......"

The snow-white lightning disappeared into the mountains, and the earth trembled.

Then a scene that made Xie Aoyu a little dumbfounded appeared, the three-thousand-meter-high mountain shook twice, and then turned into dust and scattered in all directions, and disappeared like this, only by looking at the valley that was almost filled in, did he know that there was once a high mountain there.

If you want to destroy a three-thousand-meter mountain, a sixth- or seventh-order battle emperor can easily do it, but if you want to completely destroy it like this, you won't even leave a fist-sized stone, and it will be difficult to do it in the immortal realm.

He felt dizzy as soon as he felt a little emotional.

The strength of the whole body seemed to be drained all of a sudden, and the unused combat power disappeared, and the person also fell headlong, his eyes turned black, and he almost fainted.

It's just that the imperceptible power of the demigod thunder almost made Xie Aoyu die due to excessive consumption, which means that he has the quality of a supreme god body, and if he were someone else, I am afraid that he would already die with such consumption.

Even so, Xie Aoyu still had a thought in his mind.

One thousandth of the power of the demigod thunder!
