The Berserk Demon King was puzzled, and suddenly he thought of something, and hurriedly looked inside his body, and when he saw what was happening in his body, he couldn't help but be angry.

Zhang Yu's trick is called boiling a frog in warm water, and by the time the Berserk Demon King found out, it was already too late.

More and more energy surrounded the demon king, and eventually he became the center of the whirlpool, and the energy of heaven and earth gathered towards him.

The corpses and impurities were all whirlpooled into dust, and many cultivators couldn't stop it, and they retreated one after another, you must know that the tribulation is not a joke, one after another thunder slashed, if it hit themselves, it would be over.

The Berserk Demon King was extremely angry, he also knew that the Tribulation Heavenly Thunder was powerful, and he didn't expect that Zhang Yu had entered the foundation building period, and he actually wanted to help resist the Tribulation Heavenly Thunder, which was wronged.

He hurriedly mobilized the energy of his whole body to try to suppress Zhang Yu, but knowing that it was too late, he accelerated Zhang Yu's devouring speed.

The Heavenly Master clan has no heavenly calamity, but what Zhang Yu doesn't know is that in the jade seal space in the system, the three imprints attached to the jade seal keep flickering with the energy input, and the inscriptions of the imprints continue to fly, forming a huge spell around the jade seal.

A part of the Yin and Yang Qi obtained from the Berserk Demon King directly entered the jade seal space, and the spell kept spinning, vaguely attracting the energy of heaven and earth.

Suddenly, a complicated spell flashed violently and appeared on Zhang Yu's head.

"Bang!" At the moment when the spell was suspended on Zhang Yu's head, the violent heavenly thunder instantly slashed down.

Heaven and earth flashed a light, like daylight in an instant, the first thunderbolt directly slashed the Berserk Demon King, only to see it roar angrily and raise its hands, the energy mass in its hand was just aimed at the thunderbolt, the sparks exploded, and the first thunder and lightning were neutralized.

The spell continued to flash, followed by the second, and then the third!

At first, the Berserk Demon King still had the confidence to cancel out the thunder in the sky, but later, there were more and more thunderbolts in the sky, and half of the sky was full of dazzling lightning, like a downpour, and the thunder and lightning range, and there was no grass.

Countless buildings were destroyed, and even the ghouls couldn't stand the power of heaven and earth, and many ghouls trembled and hugged their heads, hiding in the ruins and shivering.

"I said, is this a catastrophe? It's terrifying!" Zhou Hua looked at him in horror, and couldn't help but lean on Li Song next to him and ask.

"God knows, it is estimated that this grandson usually does too much evil, and the heavens can't even see it. Li Song was also confused.

Not to mention them, even those sect masters who survived the tribulation were shocked, even if they had already reached the foundation building period, they didn't dare to say that they survived this thunderstorm.

What they didn't know was that most of the thunderstorms were blocked by the Berserk Demon King, and a small number of them pierced through its body and hit the runes above Zhang Yu's head.

Every time it hit the rune above his head, the rune shone brightly, and it wasn't until it was hit and tempered ten times that the rune disappeared on the jade seal again as if it had eaten and drunk enough.

If Zhang Yu looked at the jade seal at this time, he would find that the mark on the jade seal had turned silver, and some of the blurred details had become extremely clear.

When the mark disappeared, Zhang Yu opened his eyes suddenly, and he could see the silver light in his eyes flashing away, and the biggest change was the three soul fires on the top of his head and shoulders, which represented the most direct sign of the Heavenly Master Clan.

The soul fire was faintly pale blue, and it kept fluttering.

Zhang Yu looked at the soul fire on his shoulder, knowing that this soul fire represented the level of the Heavenly Master, and he could also use the soul fire to refine tools and runes.

Usually the soul fire can be turned into a light blue tattoo in the shape of a flame, and it can only be turned into a soul fire when fighting or when needed.

This soul fire has the ability to eliminate and degree ghosts, it has a suppressive effect on ghosts, and soul fire can also control ghosts.

"Ding-dong, SS-level quest completed, please accept the reward ......"

"Ding-dong, get the ...... item"

Zhang Yu had a lot of things in his head, and the system prompts kept ringing, and Zhang Yu was in no mood to check at this time, because he always remembered that he was in the belly of the Berserk Demon King.

He looked at his palm, the power of the rules of heaven and earth flowed between his palms, and perhaps he had only truly entered the ranks of cultivators when he reached the foundation building period.

Zhang Yu turned his head to look around, and could clearly feel that the space was full of flaws, he thought about it, and a few small fireball talismans flashed out in his hand, and threw them somewhere, and a continuous explosion sounded, and he rushed over.

Suddenly, there was a white expanse in front of him, and he found that he had rushed out, and the whole city seemed to be bombed by a nuclear bomb, and the dim sky was full of debris flying in the sky.

"Help me!" Suddenly a small voice came, Zhang Yu turned his head to look, and saw that the berserk demon king was blackened by electricity, his skin and flesh were burnt, and his whole body shrunk to the appearance of a human being, and he was dying.

Zhang Yu frowned, and suddenly pulled out the Nine Heavens Xuan Sword, the sword flickered, and he turned around and was about to stab.

"Don't, just let me go, and I'll ...... Sky...... Heavenly Master Clan!How is it possible, aren't you exterminated?" The Berserk Demon King returned to his human appearance, his eyes widened, watching Zhang Yu's three soul fires fluttering, as if he had seen a ghost, he stammered and said.

"What? The Heavenly Master Clan has been exterminated?" Zhang Yu, who was originally going to stab him, couldn't help but be stunned when he heard the words of the Berserk Demon King, he felt that the Berserk Demon King must know something.

"Do you want to know why? As soon as you let me go, I'll tell you. Seeing that Zhang Yu was asking for something, a smile appeared on the face of the Berserk Demon King again, but as soon as the corners of his mouth were raised, he screamed miserably, because Zhang Yu's sword directly broke his arm.

"Since you don't say it, I don't want to hear it, go die!" Zhang Yu felt that this guy in front of him was too terrifying, if he was allowed to take a breath, the consequences would be unimaginable, and it would be better to kill him.

Perhaps sensing the murderous aura in Zhang Yu's eyes, the Berserk Demon King hurriedly shouted: "Don't, as long as you let me go, I will recognize you as the master." ”

"Oh?" Zhang Yu stopped, seriously considering the proposal of the Berserk Demon King, and at this moment the thunder and lightning had stopped, and the figure of the sword immortal could be faintly seen in the sky.

"What I'm saying is true, I know a lot of things about that world, yes, it's what you call Peach Blossom Spring, where I came from. The Berserk Demon King said anxiously, knowing how miserable the end would be if it fell into the hands of other cultivators, it was better to try its luck under the Heavenly Master.

"Okay, then I'll believe you once!" Zhang Yu hesitated for a moment, nodded in agreement, he really wanted to know what the Peach Blossom Paradise was.

Seeing Zhang Yu's agreement, the Berserk Demon King breathed a sigh of relief, and he instantly turned into a ball of light and broke away from his body and flew into Zhang Yu's hands.

Zhang Yu looked at the ball of light, his heart moved, and the soul fire on his shoulder flew out a small point, submerged into the ball of light, Zhang Yu could immediately feel that he could control the life and death of the ball of light.

Throwing the ball of light into the jade pendant for Lin Xueyue to watch, Zhang Yu put away his fighting state, and suddenly saw a few streamers flying over.
