For example, after Lei Yuanshi and the Five Elements Essence Gold were refined, they were integrated into the Thunder Sword, which improved the quality of the Thunder Sword again.

And the Moro soil and iron phantom sand are fused into the mountain seal, which makes the mountain seal more stable and has a trace of fantasy power.

After the Xuantie Essence Gold and the Great Luo Divine Iron melted, they entered the Wufu Sword.

In short, as long as Chen Feng had the right refining materials, he would take them all out, and after refining, he would use them to improve the grade of these magic weapons.

In the process of refining, the Immortal Ding and the Immortal Furnace are also undergoing some changes.

"Look, a thunderbolt whip!" suddenly shouted one of the monks onlookers.

Sure enough, a thick thunderbolt loomed in the clouds. This long whip, which was completely condensed by the power of heavenly thunder, was thousands of feet, and the destructive power contained in it made Feng's heart bristle.

"Something is not good!" Chen Feng said in a low voice.

Sou!

Finally, this thunder and lightning whip was finally condensed, cutting through the void and pumping heavily at Chen Feng, and everywhere it passed was a roaring sound of breaking the air.

"Roar!"

Chen Feng's body was bound by the thunder and lightning chains, and he couldn't break free, so he had to look up to the sky and roar, and a shock wave like substance gushed out from Chen Feng's mouth.

Syllable!

But these shockwaves were easily shattered under the lightning whip, and it seemed to have no effect at all.

Syllable!

With a dull sound, Chen Feng was struck by the thunderbolt whip, like a meteorite falling to the earth, and fell heavily on the top of the mountain where Chen Feng was.

Thundered!

With a dull sound, the prohibitions that Chen Feng had arranged on the top of the mountain exploded one after another, and the hundred-zhang-long mountain had been shattered, and Chen Feng had disappeared.

"Brother Chen!" Jian Xiaotian's face changed greatly, and he couldn't help but shout loudly, and at the same time he was about to rush towards the mountain where Chen Feng was, but he was stopped by Liu Quan.

"Don't go, the thunderstorm is not over yet, it's useless if you go, it will affect yourself. Liu Quan said.

"I don't know what happened to Brother Chen, don't let anything happen?" Jian Xiaotian was sincerely worried about Chen Feng.

"It shouldn't be fine, Brother Chen's breath is still there, and it's still very stable. Liu Quan comforted.

Having said that, Liu Quan was also a little worried, after all, Chen Feng had already survived three thunder tribulations in one go, and it would be too much of a loss if he failed at this time.

"What a powerful thunderbolt whip. The immortal who was optimistic about Chen Feng before said in a deep voice.

"Looks like you're going to lose this bet. ”

"Not necessarily, this young man's breath is very stable, and he shouldn't be injured. ”

"Then look at it again. ”

Bang la la blah!

Rubble flew around, Chen Feng's whole body flashed with thunder and stood up, the magic clothes on his body were in tatters, and the skin and flesh on his body were even more scorched, especially where he was hit by the thunderbolt whip just now, where the skin and flesh were almost completely necrotic, and even the bones inside were cracked.

"What a powerful attack. Chen Feng was also a little shocked, and while quickly repairing the injuries on his body, he used the immortal sword in his body.

Whoosh whoosh!

One after another, sword light burst out from the body, and was finally cut off by the thunder and lightning chains around the body, and then absorbed all these thunder and lightning fragments into the body.

The chain of thunder and lightning no longer came, only a long whip of thunder and lightning dancing in the sky, like a huge thunder dragon constantly circling, showing off its might.

It seems that Chen Feng's success in crossing the catastrophe should be no problem. ”

"Not necessarily, the attack just now is too powerful, I'm afraid I won't be able to stop it if I change you, not to mention that this thunder tribulation will last for a while. ”

Sou!

In Chen Feng's induction, this thunderbolt whip firmly locked on him, even if he escaped to the ends of the earth, or burrowed into the ground, he would be chased and beaten.

Wow!

The long whip whistled at Chen Feng again, this is not an ordinary attack, this thunder and lightning long whip contains the destructive power of the heavenly thunder and the will of the heavenly way, if you can't resist it, the soul will be whipped.

"Sword Qi Storm!"

Chen Feng still didn't use the magic weapon to oppress this super force, but he began to take the initiative to attack, his hands were spread, and countless sword qi shot out from his fingertips, and then continued to rotate, constantly entangled, and a powerful storm of sword qi attacked this thunder and lightning long whip.

Bang bang!

There were bursts of explosions, lightning and thunder, Chen Feng's sword qi storm had been dispersed, and the thunderbolt whip was drawn in front of Chen Feng again.

"Just in time!"

Chen Feng grabbed the thunderbolt whip with both hands violently, and his whole body surged, and suddenly the thunderbolt whip was broken inch by inch, but Chen Feng also fell into the mountain again under the huge impact and disappeared.

"Whew!"

This time, every once in a while, Chen Feng came out again, and his hands quickly grabbed it, gathering all the power of the heavenly thunder floating in the air.

"Hey, if you only have this kind of strength, you won't have a problem surviving four thunderstorms, but some minor injuries are still indispensable. Chen Feng said secretly in his heart.

Bang Bang Bang!

Sure enough, another thunderbolt whip condensed out of the clouds, which was thicker and stronger than the thunderbolt whip just now, and the destructive power contained in it was also stronger.

"Immortality Mahamudra!"

"Sky Breaker!"

"Decepticon!"

Chen Feng displayed the fist fingering and palm techniques that he had cultivated in front of the Heavenly Meteorite, and constantly bombarded the thunder and lightning whip that was whipped at him.

Finally, a thick thunderbolt whip was shattered by Chen Fengsheng, but before Chen Feng could absorb the power of these thunderbolts, two thunderbolt whips came over at the same time in the clouds, directly pumping Chen Feng out of the canopy, causing Chen Feng's body to be scorched black, and a piece of skin and flesh rolled upside down.

"This is like a catastrophe, if you survive four thunderstorms in one breath and are safe, then it is called against the sky. ”

"This is just some flesh and skin wounds, hey, envy, admiration! If I can do this every time I cross the tribulation, I'm afraid I will soon be able to cultivate to the realm of human immortals." ”

"Don't talk about you, after four thunder tribulations in one go, even our entire Heavenly Sword Sect doesn't have such a master. ”

"Not really, but there are quite a few senior brothers who have survived several thunderstorms in ten years. ”

"Whew!"

Chen Feng's mouth was full of thunder flashes, his hair stood on end, and the magic robe he had just changed into became tattered again.

"Boy, let's end here after the four thunder tribulations, although you can barely survive the fifth thunder tribulation, but it's not a good thing to rush too much in one go. Then Ta said suddenly.

"Of course, I also have this plan, this time I have survived four thunder tribulations in a row, which is enough for me to have a good understanding for a while. Chen Feng also gradually calmed down, it is indeed a good thing that his strength has improved by leaps and bounds, but it is not a good thing to be too fast, it is easy to cause a weak foundation, and there will be some changes in his cultivation in the future.

After that, the Immortal Pagoda disappeared directly into Chen Feng's sea of knowledge, and Chen Feng knew that the Dao Immortal Pagoda was going to devour the power of the Heavenly Thunder again.

A total of four thunderbolt whips slashed at Chen Feng's body, and the entire mountain peak where Chen Feng lived had disappeared, not only that, but a huge deep pit appeared on the ground, and the surrounding mountain terrain was affected.

Finally, when some immortal weapons such as the Immortal Sword were completely promoted to second-grade treasures, Chen Feng's Thunder Tribulation ended.

The aura on Chen Feng's body suddenly retracted, the clouds in the sky quickly dissipated, the sky cleared, and it took Chen Feng three days and three nights to cross the tribulation.

Four thunderstorms.

At this time, Chen Feng was already a fourth-level cultivator.

Whoosh!

After the clouds disappeared, Jian Xiaotian, Liu Quan and some other disciples of the Heavenly Sword Sect who had befriended Chen Feng stepped forward one after another, firmly surrounding Chen Feng in the middle.

Some things must be guarded against, after all, Chen Feng had found the assassination of the killer before.

But then, in the process of Chen Feng's cultivation with his eyes closed, the killer never appeared again, thinking about it, Chen Feng's crossing of the catastrophe attracted a large number of disciples of the Heavenly Sword Sect, and even a lot of human immortals came out, and if a killer appeared at this time, he would definitely be looking for death.

With the end of Chen Feng's thunder tribulation, the onlookers all talked about leaving, but the object of everyone's conversation was Chen Feng, a magical young man who had crossed the tribulation.

"It's over, this person can't be provoked, it's too demonic, if you can't kill it all at once, it will be your own end in the future. Jian Jinhuo shook his head, dispelling his thoughts of going against Chen Feng.

However, Jian Xiaotian and the others never left, and they were all quietly protecting Chen Feng around.

Finally, on the tenth day, Chen Feng finally opened his eyes.

The glint in his eyes flickered, like thunder and lightning, and in the process of crossing the tribulation, Chen Feng's cultivation of the Dark Demon Pupil also made great progress.

As soon as Chen Feng stood up, his breath soared into the sky, spreading all around, everyone felt that the space around them had fluctuated, and Chen Feng also felt that he could mobilize the power of heaven and earth with his moves, and he was more sensitive to the sensing power of the surrounding aura.

Swish!

As soon as Chen Feng's breath was closed, the whole person returned to normal, and his breath was completely constricted, at this time, Chen Feng's situation was that he couldn't see Chen Feng's reality when the immortals came.

"Haha The sword roared in the sky, and Ha Luha laughed.

You must know that the Dao Sword Xiaotian is also the realm of the sixth layer of heaven and man, if Chen Feng has two more thunder tribulations, he will really catch up with the sword Xiaotian.

"Brother Chen, congratulations, you have survived the four thunder tribulations in one go, even if there are not many people in the entire cultivation world, there are not many people who can do it. Liu Quan also stepped forward and said with a smile.

"Brother Chen, congratulations. ”

"Congratulations!"

"Congratulations!"

Everyone stepped forward to congratulate, everyone was friendly with Chen Feng, and everyone was happy to see Chen Feng so against the sky.

"Thank you Dharma Protectors, I have a treat today, please gather together, but my mountain peak has been shattered by the thunder, and it seems that I have to find a new place. Chen Feng looked at the big pit behind him and said with a smile.

"If you don't dislike it, come to me, we rarely get together, this time we have to have a good chat. Liu Quan said with a smile.
