Thunder snakes, constantly flashing with stunning light, shuttled back and forth between Zhang Yu and Thunder Purgatory, and the meaning of tyranny and destruction filled it, as if to completely erase the traces of this piece of heaven and earth!

Zhang Yu was in no hurry to temper his bones, and as the tempering deepened, his bones were as bright as glass, and in this monotonous world of thunder, it seemed a little out of place.

When the wheel of time rolled to the seventh day, Zhang Yu's whole body, except for his skull, had completed the tempering. Although the skeleton frame wrapped in internal organs looked rather eerie, it did not have any eerie atmosphere, but gave people a sense of holy brilliance.

"Bang!"

Zhang Yu couldn't help but let out a muffled snort in his mouth, and his body also retreated again and again.

Feeling the burning meaning coming from his soul, Zhang Yu couldn't help but want to frown, but was embarrassed to find that his flesh and blood had long been wiped out.

"Everything is difficult at the beginning, even the most difficult pass has passed, how can I be trapped by this last step!" Zhang Yu bowed slightly, his eyes were firm, and there was a creaking sound between his clenched finger bones.

Just now, Zhang Yu wanted to concoct it in the same way and complete the final refining of the skull, but he found that at the moment when he had just introduced the power of thunder into the skull, the power of thunder, which was originally quite gentle, instantly rose up, and frantically rushed towards his soul, as if he wanted to wipe it out.

Even if Zhang Yu's soul realm had broken through to the voyeur realm, in the face of the power of thunder that was completely restrained, he had no power to resist at all, and even had to restrain his hands and feet and dodge with all his might.

Otherwise, as long as a little thunder power is contaminated with his soul, then his soul will quickly decompose and melt like a drop of water in a boiling oil pot.

This price is so heavy that even Zhang Yu can't bear it.

At this moment, Zhang Yu must be careful, careful, and careful, he must ensure that nothing goes wrong!

After a little trimming, Zhang Yu moved again.

He gently lifted his fingertips, provoking a throbbing wisp of thunder power, carefully guiding it towards his skull.

Closer, closer......

As the power of thunder approached Zhang Yu's skull through the bloodline flames, his body, which had always been calm, couldn't help but tremble slightly.

"It must be successful!" Zhang Yu held his breath and silently cheered himself up in his heart, but he still couldn't suppress his apprehension.

"Poof!"

Between the touches, the thunderbolt easily burrowed into Zhang Yu's skull, shuttling unscrupulously, as if searching for something.

However, Zhang Yu had already locked all his soul power in the depths of the Sea of Knowledge, in addition to covering it with layers of blood and flames, he also imposed a series of prohibitions, blocking the water of his soul power, and the method was so secret that even he almost forgot where to hide.

All the hard work was not in vain, no matter how the thunder power searched, it still found nothing, and because the process of wandering consumed a lot of energy, it gradually showed fatigue, Zhang Yu seized the opportunity and immediately refined it into his skull.

When the soul power was absorbed by Zhang Yu, the color of the area with the size of a fingernail on the skull also changed from miserable white to more translucent, and the aura became more powerful.

Looking at the inexhaustible power of thunder in the thunder purgatory, Zhang Yu also had a feeling of unfinished.

"If I can absorb all these thunder powers, I'm afraid that even in Zhongzhou, where the strong are like clouds, I can also be unscrupulous!"

With such thoughts turning in his heart, Zhang Yu's silent mood also made waves again.

But soon, he shook his head and said with a wry smile: "Zhang Yu, you still don't daydream, hurry up and get over the catastrophe in front of you." ”

Calming his mind, Zhang Yu turned his gaze to the power of the thunder that fell around him again, concentrated, and pulled a thunder snake again, merging into his skull.

A small piece, a small piece of fusion refining, Zhang Yu did not have the slightest impatience.

His heart is like water, and he completes the final tempering step by step.

Strength never comes out of thin air, if you want to get it, you must pay the equivalent blood and sweat, this truth is easy to understand, but there are very few people who can really stick to it, and most of them are halfway through the halberd and sink into the sand.

One percent, two cities, fifty percent......

The skull has completely turned into a glass crystal, and it is already close at hand!

......

Outside of the Thunder Purgatory, whether it was a demon beast or a human, the initial impatience had long since been worn off, and one by one they were calmly waiting around the Thunder Prison, and some even began to meditate cross-legged, obviously ready for a protracted battle.

"Brother Lei, come, eat some barbecue, stay here, my brother has faded out of his mouth!" A thin figure just landed, and it was to take out the flesh of an unknown demon beast that was roasted golden and constantly flowing with oil and water from the storage ring.

Seeing this, the face of the strong man known as Lei Ge suddenly changed, and the demon beast meat in the hands of the person who snatched it was incinerated into ashes. Then the spiritual power on his feet surged, and he kicked him to the ground.

"You bastard, are you looking for death?"

Hearing Brother Lei's angry reprimand, the thin man looked aggrieved, and just as he wanted to defend himself, he saw Brother Lei constantly glaring at him, turned his head, and glanced at the many fierce lights around him who were looking at him coldly, and he immediately sweated like rain!

In an instant, he came to his senses, and hurriedly knelt on the ground, begging loudly: "Brother Lei, I was wrong, I didn't mean to, please spare me this time." ”

"You bastard, you are simply innocent, if I don't teach you a good lesson today, I am angry in my heart!" As he spoke, Lei Ge kicked the thin man again, and suddenly a pig-like wail sounded from the thin man's mouth, spurting blood from his mouth and nose, looking miserable!

Although everyone knew that this Brother Lei was just making a show for those thousand-year-old demons, no one was stupid enough to poke it.

Seeing that the thin man had been punished, those cold eyes gradually shifted away from him.

"Hmph, remember your little life first, and I'll settle accounts with you when I go back! Don't get out of here!" Seeing that the goal has been achieved, Brother Lei also retracted his strength and said viciously.

"Thank you, Brother Lei, for not killing. The thin man was so grateful that he didn't even have time to wipe the blood on his face, and he didn't even have time to wipe the blood on his face.

Although he looked seriously injured, it was just some skin injuries, and there was almost no loss of strength.

And for Brother Lei's punishment, he did not have the slightest complaint in his heart, but was grateful.

You must know that the moment he took out the demon beast meat, the eyes of almost all the monarch-level demon beasts were fixed on him, and he almost thought that he was already a dead man.

The jungle eats the jungle among monsters and beasts, and obeys the most primitive law of the jungle. Every day, I don't know how many demon beasts are going to be buried in the mouths of the same clan, so for the death of demon beasts, these monarch-level demon beasts have long been commonplace.

But at this time, the thin man actually took out the demon beast meat in front of the public, intending to eat it, it was naked, naked, naked, and slapped in the face, not to mention that now the demon beast side has an absolute advantage.

If that Lei Ge hadn't taught that thin man a lesson, there would definitely be a demon beast that would have wiped him out.

After such a small episode ended, the powerhouses looked at the purgatory again, and the thunder purgatory, which had been calm, unexpectedly had abnormal energy fluctuations, and everyone suddenly became excited.

"Chongbao! it must be Chongbao!" exclaimed.

"The fact that this thing can be born from endless thunder shows that its quality is extraordinary, if I can get it, maybe I can break through the current boundaries and achieve a general-level body!" he muttered softly, the fire of greed burning more and more in the demon's eyes.

"Mine, all of them are mine, whoever robs me will die, kill, kill, kill!" A demon beast suddenly turned into its main body, swallowing a human warrior on its body in one bite, and the scene was suddenly chaotic and out of control!

"Kill!"

The sound of killing was everywhere, and in an instant, several people were bleeding and dying, and the corpses with angry eyes showed unwillingness.

The rich smell of blood wafted with the wind, and it aroused the instinctive beastliness in the depths of the demon beast's bloodline, and in the deafening roar, a huge demon beast with a small head and body length of several zhang and dozens of zhang fought frantically, and the bloody scene made people smell the color change.

"All ready, contact Xiaoyu at any time!" The chaotic scene obviously exceeded the expectations of Mo Chen and the others, and in this way, it was more conducive to the implementation of their plan.

Deliberately avoiding the various battle groups, Jian Wangui and the others quietly approached the Thunder Purgatory.

Even though they were already careful, they still caught the attention of some old demons.

"Weak human beings, they still want to fish in troubled waters, hehe, let's become the blood food of my ancestors. "A terrifying tiger demon at the peak realm of the monarch level opened its bloody mouth and swallowed it towards the sword Wangui.

"You go first, leave it to me here!" Jian Wangui burst out, and it shot out like lightning, and the sword was instantly unsheathed, and the sword slashed at the tiger demon.

"Poof!"

The dazzling sword light surged with endless sharp aura, and it tore apart the powerful defense of the monarch-level demon beast in an instant.

Blood splattered, and screams resounded throughout the universe.

The tiger demon at the peak of the monarch level obviously didn't expect that Jian Wangui would be a hidden master, and when he was careless, he paid the price of blood!

In the scarlet eyes, there was a fierce flame that was almost substantial, and the tiger demon roared angrily, and the tyrannical aura roared out, and pounced fiercely towards Jian Wangui.

"Hmph, looking for death, I'll fulfill you!" Jian Wangui snorted coldly, and the sword intent full of destruction also burst out, colliding with the tiger demon's claws.

A storm of terrifying energy swept out, and the two figures retreated almost simultaneously.

Jian Wangui's feet were slightly forced, and the terrifying power on his body was unloaded, and the originally somewhat fluctuating aura returned to calm again.

"Human, I'm going to kill you!" Looking at the blood that kept flowing on his body, the tiger demon gritted his teeth and said.
