Looking at the sword light that disappeared at the end of his sight, Su Fu's face showed a little helplessness, he knew that Tie Jian had discovered the existence of Lei Jing, if it was before, he would definitely be overjoyed, but now he could only watch Tie Jian eat alone.

"The thunder energy here is so terrifying, and the condensed thunder essence... The grade must be very high..."

Su Yu heard Xuan Ku say that the lowest thunder essence in the ninth heaven is the seventh-grade thunder essence, most of them are eight-grade thunder essences, and the nine-grade thunder essence rarely appears, and it has appeared twice since the thunder pool was opened.

Slowly exhaled, Su Yu took out another Nine Treasures Blood Pill and swallowed it in his abdomen, abandoning the distracting thoughts in his heart, and cultivating without distractions, although the thunder here is terrifying, but the effect of refining the flesh body is excellent, with the effect of the pill, with Su Defeat's current body, he can still withstand the tempering of these thunders in a short time.

Rumble...

The bright light burst out again on the stone platform, and the white pi practiced through the sky, and the white expanse was like the Milky Way falling for nine days from a distance, and the momentum was huge, and it fell on Su Fu's body, only to see that the surface of his skin directly cracked out countless blood marks that could be seen deep bones, and the blood was dripping, and in an instant, Su Shi turned into a bloody man.

At the same time, the demon saint blood that permeated the heavens and the earth frantically converged towards his body, turning into an incomparably majestic essence and blood energy, filling his limbs and bones, and finally after Su defeated the refining, these essence blood energy quickly merged into Su Defeat's flesh and blood, and Su Defeat could clearly feel that the flesh and blood that was reborn again were more vigorous.

At the same time, the vitality energy dissolved by the Nine Treasures Blood Pill nourished his physical body at all times.

After gradually getting used to these white thunders, Su Yu began to practice the reincarnation immortal sword body supernatural power.

Once born and twice matured, with the experience of cultivating the sword vein, Su Fu took many detours when he practiced the second sword vein, but the cultivation speed was still not as good as before, after all, without the thunder essence, even if the demon saint blood in this heaven and earth was a lot richer, it was still a drop in the bucket for him.

This practice is a few more days.

Until a certain moment, Su Yu opened his eyes suddenly, at this time, the stone platform under him was shaking violently, he quickly got up, and looked at the world in front of him with some surprise, only to see that the whole world suddenly crumbled, as if it was about to collapse, and the thunder that originally roared between heaven and earth also became more violent, setting off countless storms sweeping across heaven and earth.

An extremely oppressive aura enveloped Su Yu's heart, and in his perception, the world in front of him seemed to be about to crack.

At the same time, above a towering mountain, an extremely old figure sat quietly, the old Taoist clothes moved in the wind, the old Taoist originally closed his eyes, but at this moment, his eyes opened suddenly, and his expression suddenly became solemn, "What's the matter... It's only been more than 100 years since the last lightning crash, how did this time come so quickly..."

His hands quickly sealed, and behind the old Taoist, there were Dao patterns in the sky in vain, and these Dao patterns were connected one after another, like a net of heaven and earth, shrouding towards the heaven and earth in front of him, and at the same time, the old Taoist said: "The thunder crash is coming, you will quickly exit the thunder pool..."

Rumble...

The voice of the old Taoist seemed to turn into a heavenly sound, echoing in the Nine Heavens of the Thunder Pool.

Whether it was Su Yu who was in the ninth heaven, or Mu Yang and the others who were in the seventh heaven, they all heard this.

"Thunder Crash..."Mu Yang's face changed greatly, as if he had heard something extremely terrifying, and his breathing gradually became short, "Hurry up... Evacuate the Thunder Pool..."

On the stone platform, Xuan Ku and the others, who were originally cultivating, were also shocked by this voice, and each of them had a solemn expression, and hurriedly got up, followed by Mu Yang, and withdrew from the seventh heaven.

"Was that the Guardian's voice just now?" asked Langzhu Tears softly.

"Hmm... I didn't expect our luck to be so unlucky this time, the thunder crash that is rare for a thousand years actually let us bump into it, and this time the thunder pool cultivation can only be done today..."

Mu Yang's body burst out of the majestic and majestic true yuan, surrounded by an ocean of terrifying fluctuations, he held a simple style of spear, the spear out of the dragon, shooting out of the spear rainbow for several miles, accompanied by the deafening sound of the sky, the thunder sea in front of him torn a path.

"Keep up..."Mu Yang's figure turned into a long rainbow and shot out, he kept shooting, and with extremely powerful means, he split the thunder sea.

It was as if a storm was coming, and a depression enveloped everyone's hearts, and no one spoke again, but they were all rushing to the road.

At the same time, in the ninth heaven, the voice of the old Taoist swept away under the heavenly dome.

"Thunder Collapse..."Su Cheng looked at the Lei Hai in front of him, his expression was extraordinarily solemn, when he was chatting, he remembered that Xuan Ku had mentioned that the Lei Chi was evolved from the corpse of the Demon Saint, and the space was not stable, and there would be signs of collapse from time to time.

"Thunder Crash... It usually starts from the ninth heaven..."

Su Yu had gradually felt that the void around him had become extremely unstable, especially as those thunderbolts turned into storms and swept away, small spatial cracks loomed, and soon, the space of the Ninth Heaven was about to collapse.

"This place can't be stayed. Su Yu tried to sense the existence of the iron sword, but the thunder here was too violent and completely blocked his perception, and after trying to no avail, he immediately made a decision to evacuate the Ninth Heaven.

Sonor!

The high-pitched sound of the sword rang out suddenly, and a dazzling sword light burst out from the thunder sea in front of him, blazing incomparably, covering the thunder light in the sky, and rushing towards Su Defeat.

Seeing that sword light, Su Yu secretly breathed a sigh of relief, stretched out his hand and grabbed the sword light, and before he had time to take a closer look, his figure had already rushed towards the entrance of the Eighth Heaven.

Rumble...

Rumble...

And not long after Su Yu left the Nine Heavens, the void of the entire Ninth Heaven began to really collapse, the turbulent current pierced through the air, countless spatial turbulences surged, and the thunder turned into a storm and spread, until finally, the entire thunder sea turned into a storm, engulfing the stone platforms that were originally suspended between heaven and earth, and the patterns on those stone platforms bloomed together to resist the impact of these storms and turbulence, but in just a few breaths, these stone platforms collapsed one after another.

For all this, Su Yu naturally didn't know, as soon as he returned to the eighth heaven, Su Yu noticed that the oppression between the surrounding heaven and earth was suddenly much smaller, he didn't dare to stay, hurriedly hurried, rushed towards the seventh heaven, the sword intent turned into a storm and swept away on him, tearing the thunder in front of him, and at the same time, the supreme sword instantaneous technique continued to be cast, increasing the speed to the limit.

Looking at the past from afar, in the vast thunder sea, a sword light flickered.

Half a day later, at the entrance of the thunder pool, the ripples in the space spread rapidly, and the figures of Muyang and his party slowly emerged, all of them were extremely embarrassed, and as soon as they came out of the thunder pool, both Muyang and Xuanku and others breathed a sigh of relief.

"It's finally out... I almost thought I'd die in it this time..."

"Well, fortunately, there are Muyang's seniors to open the way for us, otherwise, with our strength, if we want to come out, it will take a day..."

"Seniors, people have already come out. Mu Yang breathed a sigh of relief slightly, and bowed to the old Taoist not far away.

The old Taoist said lightly: "There is one more person." ”

Mu Yang naturally knew who the old Taoist was talking about, and hurriedly said: "What the senior said refers to the young man who walked with us? Some time ago, he had already died in the thunder sea. ”

"He didn't die, he came out quickly. The old Taoist said, and before he finished speaking, he closed his eyes......

"What...", everyone's faces changed in unison.
