Chen Qingyang and the others looked in the direction pointed by the Xuanlie Demon Immortal, and found that the large area of the sky was shrouded in black clouds, revealing a vast aura of oppression and vastness.

"My lord, what are your plans?" Moqi asked again.

"The Thousand Hades Demon King is left to me to deal with, you can stop the Sky Eclipse Demon King from crossing the tribulation, don't let him succeed in the tribulation, and also, this is the soul sigil I refined, if you really stray into that killing array, I can easily find your location, and I will do everything I can to rescue you."

As he spoke, the Xuanlie Demon Immortal waved his hand, and four dark purple soul runes appeared in front of Chen Qingyang's eyes.

Mo Qi frowned slightly, and said, "I'm afraid this is not needed, right?" ”

Although this soul sigil was only attached to their bodies, it would not have any effect on their souls and strength, but no one knew if the Xuan Lie Demon Immortal still had any backhand.

"What, don't believe me?" Xuan Lie Demon Immortal glared at the demon and said.

Mo Qi's face was slightly embarrassed, and he glanced at Chen Qingyang.

So far, they have no other choice, if they retreat at this time, and no matter what the consequences will be after the Eclipse Sky Demon King succeeds in the tribulation, even the Xuanlie Demon Immortal, I am afraid that they will not be allowed to retreat safely.

"Big Brother Demon, we are now in the same boat as Lord Demon Fairy, and he is also thinking about our safety, so we should trust each other." Chen Qingyang stood up and said at this time.

Seeing Chen Qingyang say this, Mo Qi could only nod helplessly.

Then the four soul sigils attached to the backs of Chen Qingyang's hands and the four of them, forming a unique imprint.

Chen Qingyang wanted to use his Divine Thoughts to carefully feel the mark on the back of his hand, but found that Divine Thoughts couldn't get close to it at all, and it was even more impossible to eliminate it.

"Boom!"

Suddenly, a deafening thunderclap sounded in the sky, followed by a distant void wind that swept through the entire world.

The black clouds in the sky began to rotate in the same direction, and at the same time, the color of the sky gradually changed, and a dark red light penetrated through the black clouds, which was very strange.

"The Thunder Tribulation is going to land soon, let's go!"

After the Xuanlie Demon Immortal finished speaking, with a wave of his big hand, the energy swept Chen Qingyang and them up, and then quickly flew towards the distant sky.

After a while, a suspended island appeared in Chen Qingyang's line of sight, Chen Qingyang squinted, and could vaguely see a figure sitting on the island, surrounded by a large array of energy, and at the same time, a black mist floated strangely around the island, even if it was far away, Chen Qingyang could sense the familiar and evil aura.

Obviously, that black mist was the one that the mysterious national teacher had turned into.

"Demon King, they are really here!"

The national teacher looked up at Chen Qingyang and their direction, and said in a deep voice.

At this time, the Sky Eclipse Demon King still hadn't opened his eyes, and his body was motionless like a statue.

"Don't worry, just buy me a quarter of an hour." The Sky Eclipse Demon King said lightly.

Obviously, he was very confident in his crossing.

"Understood." The national teacher said gloomily.

"Boom!"

There was another roar of thunder, and the dark red light pierced through the layers of black clouds, shining on the sea of burial immortals, giving people a powerful feeling of oppression, as if the end of the world was coming.

At the same time, Chen Qingyang and their black clouds had formed a huge whirlpool, and terrifying purple-red electric snakes appeared from the black clouds, and quickly disappeared into the huge whirlpool.

In less than half a minute, the whirlpool became more and more turbulent, forming a huge whirlpool of nearly a hundred kilometers, and the surrounding heaven and earth aura was also completely chaotic, and it was constantly sucked into the eye of the whirlpool.

This was the first time Chen Qingyang had seen this kind of scene of crossing, and the terrifying and vast heavenly power made his chest seem to be pressed against a thick and majestic mountain, and it was a little difficult to breathe.

"Xuanyeol!"

At this moment, a majestic voice descended from the sky.

Immediately after, a demon cultivator who looked exactly like the Xuanlie Demon Immortal appeared in front of Chen Qingyang and them.

The Thousand Demon King has finally appeared!

At this time, the aura on the body of the Thousand Hades Demon King seemed to be even more powerful than the terrifying thunder tribulation in the heavens, which made Chen Qingyang and them shudder.

"Qianming, the grievances between you and me should also be ended." Xuan Lie Demon Immortal glared at the Thousand Hades Demon King with a cold gaze and said.

It should have been his own body, and he had already turned into an immortal, but it was a pity that all this ruined the twins who were born at the same time as him one by one.

Their brotherhood was also completely severed as early as 10,000 years ago.

"It's time to decide, but you lost to me 10,000 years ago, and now you, do you still have a chance to win?"

As he spoke, the body of the Thousand Hades Demon King continued to expand, and finally turned into a giant ape that was nearly a hundred meters tall.

The Demon King Clan is the remnant of the legendary Ancient Era Fighting Holy Ape, and has an extremely terrifying fighting talent.

Now that the Thousand Hades Demon King has completely fused with the body of the demon fairy, he does not need to cross the catastrophe and directly step into the demon fairy realm.

"Why don't you try it?"

After speaking, the body of the Xuan Lie Demon Immortal also swelled, and soon turned into a giant ape nearly 100 meters long.

"Click!"

The surrounding void could not withstand the power of the two demon immortals, and it had already begun to collapse one after another.

"Your strength and I are enough to destroy the Demon Cultivation Realm, dare to follow me into the Ancient Killing Array?" The Thousand Hades Demon King looked at the Xuanlie Demon Immortal with a defiant gaze and said.

The strength of the two of them has almost reached the limit that the space of the Demon Cultivation Realm can bear, if a big battle starts, I am afraid that it will not be long before the entire space of the Demon Cultivation Realm will collapse, and finally fall into the endless space death domain and turn into dust.

"Why fear you?" Xuanlie Demon Immortal said coldly.

Then the two giant apes flashed towards the deeper sky, and soon entered an ancient killing array and disappeared.

"Boom, boom, boom......"

After a while, there were terrifying bombing sounds in the killing array, as if the world was destroyed.

Fortunately, the Ancient Killing Array was left by the strongmen of the Ancient Era, and it was enough to withstand the battle of the two demon immortal strongmen.

According to this level of fierce fighting, the two brothers may not be able to tell the winner for a while.

Then Chen Qingyang and their eyes stared at the small island suspended in the distance.

"Boom!"

Suddenly, a huge thunderclap shook, and a purple thunderbolt like a divine dragon slashed down towards the island.

"The thunderstorm has begun, do it!"

Demon Qi's face changed slightly, if the Sky Eclipse Demon King was allowed to cross the tribulation, none of them would be able to leave alive.

The Purple Thunder Tribulation ruthlessly slashed at the defensive formation above the island, destroying it in less than a moment, and then slashing at the Sky Eclipse Demon King's Heavenly Spirit Cover.
