Thunder mysteries are above all kinds of mysteries. Fire, water, and so on are just as strong. But compared to thunder, this is not a level at all. Thunder is the power of heaven's punishment. It is itself a being that is high above all things.

There was a slight thunderous sound in his ears, and Xu Feng felt his breathing become short. Thunder has a value and effect that far exceeds that of fire.

"Go and see!" Xu Feng tried his best to calm down the feelings in his heart, and said to Liu Qianru with a trembling voice, obviously Lei Xuanwu's temptation made him unable to calm down at all.

Liu Qianru also nodded vigorously, Lei Xuanwu is precious enough to make people burst their heads, no one wants to miss it.

Xu Feng stretched out his hand to pick up Liu Qianru, although Liu Qianru was tall, but her weight was not heavy, Xu Feng hugged her, pressed her body, felt the soft elasticity on it, and couldn't help but feel her heart flutter.

Although Liu Qianru is shy, she would rather stay with Xu Fengyi than staying alone in this strange place.

Walking along the sound, I passed through several connected caves, and the thunder roared even louder. Xu Feng walked quickly, and soon arrived at a space, compared to the dimness of other caves, this cave was bright and dazzling. Xu Feng fixed his eyes, and the lightning flashed continuously, illuminating the entire cave.

In the center of the cavern, a green cactus ball thunder was there. And the electric light in the cave is the lightning flash.

"Green Rock Xuanlei!" Liu Qianru felt that her breathing was also heavy, and she couldn't imagine that the cliffs connected to this cave actually contained three kinds of heaven and earth mysteries, and among them were the most precious and domineering thunder objects.

Liu Qianru took a deep breath, looked at Xu Feng who was shining in her eyes and said, "Remember this position, and come back to get it in the future." ”

"In the future?" Xu Feng was stunned, looked at Liu Qianru and said, "Why not now?"

Liu Qianru listened to Xu Feng's words, and couldn't help but glance at Xu Feng and said, "I just don't dare to provoke Lei Wu if I am not seriously injured." You don't even have five grades, and you are even more looking for death if you provoke thunder. ”

Hearing Liu Qianru's words, Xu Feng frowned, he naturally knew that Liu Qianru's words were reasonable. However, his situation at this time could not wait at all. Fifteen days passed in the blink of an eye, and he almost reached the fifth grade, but because of Liu Qianru, he still failed.

Xu Feng looked at the thunder thing in front of him, his heart was ruthless, no matter what, he had to step into the fifth grade, looking at this lightning flashing thunder thing, Xu Feng had no doubt that if he could refine and devour it, his strength would definitely soar, even if it reached the sixth grade, it would not be a problem, after all, this was the Heaven and Earth Treasure.

Xu Feng carried Liu Qianru to a safe position, put Liu Qianru in one place and said to her, "You wait here, I'll try." ”

Under Liu Qianru's sluggish gaze, Xu Feng walked towards Lei Xuanwu and operated the Dao Xuanwu at the same time. Xu Feng's confidence in daring to provoke Xuanwu came from Purple Thunder. Purple Thunder was able to devour Ling Hua's Lei Zhenzi, and he didn't know if he could fight against Lei Xuanwu.

The most important thing is that Xu Feng remembered that Zi Lei had to be in the situation again and again. I always feel that Purple Thunder itself is a kind of heaven and earth mystery, and it is an extremely high-level kind. After all, he had never heard of other heaven and earth thunder that could devour thunder and lightning.

As if feeling Xu Feng's approach, the green rock thunder began to riot, and the thunder and lightning with thick chopsticks came out of its body, and slammed into the stone wall of the cave, and the hard stone wall was blasted by the thunder and lightning, and instantly turned into powder and appeared a small pit.

Looking at the power of thunder and lightning, Xu Feng smacked his tongue, thinking that the attack of this thunder and lightning was no less than that of Lei Zhenzi. The residual thunder of Xuan Lei alone can burst out with such power, so how terrifying will Xuan Lei as the main body?

Xu Feng took a deep breath, the Dao Xuan Sutra was driven frantically, and under Xu Feng's drive, he could faintly feel the purple thunder on his forehead, and the purple thunder that was originally immersed in his forehead also flickered at this time.

At the same time as the purple thunder flickered, Xu Feng gritted his teeth and walked quickly towards the front. Xu Feng's actions instantly alarmed the green rock purple thunder, and several thunderbolts bombarded towards Xu Feng.

Liu Qianru looked at these thunderbolts with great power, and shouted with fear: "Xu Feng, hurry up." ”

However, what made Liu Qianru's eyes widen was that the thunder and lightning hit Xu Feng's body, but it didn't make Xu Feng take a step back, but the thunder and lightning seemed to be decomposed, and it was swallowed up by Xu Feng's body, and Liu Qianru could faintly see that Xu Feng had purple light flashing on his body.

Liu Qianru wiped her eyes, and after being sure that what she saw was the truth, she couldn't help muttering in astonishment: "He's not afraid of thunder?"

Just when Liu Qianru couldn't understand this, a few more thunderbolts slashed at Xu Feng, but just like just now, they were decomposed and swallowed by Xu Feng when they split on Xu Feng's body.

"This guy is not afraid of lightning slashes? Could it be that he has been struck too much? He has already ignored lightning swords?" Liu Qianru looked at Xu Feng in surprise, thinking of Xu Feng's shamelessness, the more she thought about it, the more likely this is this, this guy himself is the master of lightning slashing, maybe he is really used to being slashed, so he doesn't care.

Xu Feng naturally didn't know about Liu Qianru's slander, otherwise he would definitely be furious: How can I be the master of the lightning strike? You were just thunderstruck, and your whole family was thunderstruck!

Xu Feng, who kept walking into Xuan Lei, was overjoyed in his heart, just as he expected, every time the thunder struck him, the purple thunder would differentiate and devour, and at the same time help temper his body. Xu Feng could feel the purple thunder spinning wildly, and a trace of purple thunder spread throughout his body.

At the same time, Xu Feng could find that after the purple thunder devoured the thunder and lightning, it was also constantly growing.

In Liu Qianru's incredible gaze, Xu Feng walked to a distance of less than one meter from Xuan Lei. Liu Qianru couldn't imagine how Xu Feng was safe and sound under such a dense thunderbolt, and the thunder and lightning just now, even if Zhou Yang and the others were together, was definitely the result of serious injuries. But for this teenager, it had no effect at all.

"Is this guy a human being? How can he do this with a Cheng dù who is not a five-grade person? Is it really a Cheng dù who is so shameless that he is not afraid of splitting?" Liu Qianru muttered to herself.

Xu Feng looked at the green rock Xuanlei in front of him, and stood there straight, letting the thunder and lightning that erupted in the Xuanlei slash him. Thunder and lightning slashed at Xu Feng's body, making people feel jaw-dropping, but Xu Feng's purple thunder was slowly growing, and the speed of rotation on his forehead was also increasing.

The Xuanlei Riot became stronger and stronger, but Xu Feng stood there without moving, swallowing Xu Feng who had devoured so many thunderbolts, he felt that in his skeletal body, there was a strong flow of air, Xu Feng knew that this was the flow of qi, which made Xu Feng very happy at the same time, he did not take this opportunity to break through to the fifth grade. Instead, he frantically ran the Dao Xuan Sutra, and then worked hard to control the purple thunder.

To Xu Feng's surprise, he was just a thought, and the purple thunder that was originally spinning wildly on his forehead suddenly shifted to the position of his palm.

Looking at a purple thunder flower appearing in his palm, Xu Feng gritted his teeth, looked at Xuan Lei not far away, and stretched out his hand to grab Xuan Lei.

"Xu Feng, are you crazy?" Liu Qianru's eyes widened, looking at Xu Feng's move in disbelief, this guy actually wanted to recover the heaven and earth Xuanlei like this.

Even the thunder mystics and thunder warlocks have to make countless preparations in the face of the heaven and earth thunder, and then use all kinds of magical powers to dare to take the thunder. However, she didn't dare to think about going directly to catch the heaven and earth Xuanlei with her hands.

And the man in front of him who ate the leopard's gall did such a thing.

Liu Qianru closed her eyes, not daring to look at Xu Feng's blurred appearance of being blown up by Xuan Lei.

"Bang ......"

Just as Liu Qianru thought, a violent explosion remembered, Liu Qianru's mind instantly appeared a situation of flesh and blood scattered all over the sky, Liu Qianru sighed and slowly opened her eyes.

But she was mentally prepared, but the situation in front of her made her stay still. I saw that the familiar person was still standing there, although the blood on his palm kept falling, but Xuan Lei was grabbed by him.

Liu Qianru looked at Xu Feng's hands with wide eyes, and on the blood-covered hands, there was purple light circulating, and the purple light wrapped Xuan Lei, and Xuan Lei was crazy in it, and Xu Feng's face was pale every time he rioted.

He actually grabbed Xuan Lei with his hand. Liu Qianru muttered to herself, and there were huge waves in her heart, which seemed to Liu Qianru to be incredible. Even a thunder mystic with a ten-rank strength would never dare to do such a thing.

Xu Feng grabbed Xuan Lei, as he expected, Purple Thunder did have a suppressive effect on Xuan Lei. But the purple thunder is too small after all, although it can devour and suppress the Xuan Thunder. But the power of Xuan Lei's explosion made him feel a great impact.

This impact with waves of thunder and lightning hit Xu Feng's body, making him feel his blood and qi tumbling violently.

"I don't believe it, I can't refine you. Xu Feng gritted his teeth to resist the impact, the Dao Xuan Jing was running wildly, the purple thunder no longer needed his control, it was completely independent to suppress the Xuan Lei, and it covered the entire Xuan Lei to get the purple thunder, and began to devour the Xuan Lei, every time the Xuan Thunder was swallowed, the purple thunder grew by one point, and the strong purple thunder began to temper Xu Feng's body.

Xuan Lei was swallowed by the purple thunder, and the riot was even more terrifying, and a terrifying thunderbolt burst out and hit Xu Feng, Xu Feng finally couldn't bear it, and blood overflowed from the corner of his mouth.

"I'll fight with you!"

Xu Feng, who felt the blood and qi rolling, gritted his teeth and grabbed Xuan Lei hard. This is a fight, if he wins, his strength will definitely change dramatically, it will definitely not be just five pins. Of course, if he loses, then he ......

However, when it came to this, Xu Feng still had no chance to choose again. He frantically suppressed the Xuan Thunder, waiting for the Purple Thunder to devour and refine it little by little.
