The moment I came out, the air around me became extremely bloody and heavy.

And in its hollow white bone eyes, there were flames burning and ice surging!

When the pair of huge bone wings spread out, they covered the entire sky.

With such a huge body, even the earth would be as small as a ping-pong ball next to him.

"roar!!!!"

The ghost of the Ice and Fire Demon Lord roared to the sky.

The terrifying power and fluctuations caused the surrounding heaven and earth to tremble wildly.

In particular, the continent below Ling Yan began to shake rapidly, as if it would be completely shattered in the next moment.

However, although it looked that way, when Cecilia looked closely, she was surprised to find that there was not even a crack in the ground below.

"This seal is okay, right? At least, the undead spirit of the Ice and Fire Demon Lord doesn't have the strength to break it!"

Ling Yan said with a smile. Cecilia breathed a sigh of relief after hearing Ling Yan's words. It meant that her reincarnation mission might have been completed.

"roar!!!!"

As if sensing the seal on the earth, the spirit of the Ice and Fire Demon Lord looked coldly towards Ling Yan and Cecilia.

However, this glance made the fire and ice in his eye sockets tremble wildly, as if he had seen something terrifying.

"Did you recognize me? You only recognized me now, you're really a bit clueless!"

Ling Yan smiled helplessly.

"brush!!!"

Without waiting for the other party to speak, Ling Yan disappeared from the spot in an instant.

When he appeared again, he was already in front of the Ice and Fire Demon Lord's Undead.

Although Ling Yan's figure was as small as dust, his sudden appearance still frightened the Ice and Fire Demon Lord so much that he almost fell from the sky.

"Elemental Seal!!"

Unfortunately, before the Ice and Fire Demon Lord could make any move, Ling Yan had already slapped him directly on the center of his eyebrows.

“Buzz!!!”

In an instant, countless mysterious runes began to spread rapidly from the center of the Ice and Fire Demon Lord's eyebrows, and these runes instantly covered the entire body of the Ice and Fire Demon Lord.

In just a moment, the Ice and Fire Demon Lord was imprisoned in place.

The undead spirit of the Ice and Fire Demon Lord was horrified to find that he was not even qualified to move.

"Do you want to kill him yourself, or should I help you?!"

Ling Yan looked back at Cecilia.

"Ah? It's sealed already?"

Hearing Ling Yan's words, Cecilia immediately opened her mouth wide.

Ling Yan had said before that he wanted to practice the power of the void well, and she thought that even Ling Yan was not completely sure. However, looking at the appearance in front of her, why did it seem as if Ling Yan was doing it as easily as drinking water?

"It's just an ordinary Saint King-level BOSS. If you don't take action, I will!"

Ling Yan said indifferently.

"I'll do it, I'll do it, I'll do it. Otherwise, I won't be able to contribute anything and I'm afraid the mission won't be completed!"

Cecilia didn't hesitate when she heard that.

“Buzz!!!”

The next moment, with a wave of Cecilia's hand, the giant quantum sword behind her instantly soared into the sky.

"boom!!!!"

In an instant, a terrifying magical power burst out from the giant sword.

This technologically advanced giant sword instantly surged with a large amount of purple energy.

The energy instantly turned into a giant purple sword that was ten thousand meters long.

"Quantum Annihilation Slash!!"

Cecilia clenched her right hand into the air and slashed forward fiercely.

“Shhh!!!!”

In an instant, the surrounding air was torn apart, and at the same time, a terrifying sword energy that was thousands of kilometers long slashed down fiercely towards the sealed undead spirit of the Ice and Fire Demon Lord in the distance.

“Boom boom!!!”

A deafening roar resounded throughout the world at this moment.

A huge damage value instantly appeared above the head of the Ice and Fire Demon Lord.

Ling Yan just took a look and found that the total blood volume was less than one ten-thousandth.

"Ahem, is this defense so high?"

When Cecilia saw the damage, her face immediately turned red, and she was also a little annoyed. Why did you make the defense so high for no reason?

Isn’t this bullying honest people?

In anger and humiliation, Cecilia swung the giant sword and madly slashed down at the undead demon of ice and fire.

“BOOM BOOM BOOM BOOM BOOM!!!”

In an instant, earth-shaking roars spread throughout the world.

The health of the Ice and Fire Demon Lord's undead spirit was also slowly decreasing.

"Well, that's got to wait!"

Seeing this scene, Ling Yan felt helpless.

"Destruction Field!!!"

Then Ling Yan directly opened the domain here.

“Buzz!!!”

In an instant, the vast domain gushed out, instantly enveloping the undead spirit of the Ice and Fire Demon Lord.

[Ding... The Ice and Fire Demon Lord's Undead spirit is being eroded by the domain, and all attributes have decreased by 80%]

At this moment, a prompt sound rang in Cecilia and Ling Yan's minds.

Cecilia looked at Ling Yan in disbelief.

An 80% decrease in all attributes?

This is a Saint King level BOSS!

Although general red field skills can also achieve such a powerful effect, they are only useful for BOSS below the emperor level. The emperor level can only achieve a 60% reduction.

The Saint King level can only reduce 40 attributes.

In other words, the skill used by Ling Yan is dark red?

And it’s an extremely rare domain skill?

"What are you looking at me for? Hit me!"

Ling Yan rolled his eyes at Cecilia who was still in shock. Cecilia then came to her senses and quickly mobilized all her strength to launch a crazy attack.

Sure enough, as all of Cecilia's attributes were weakened, her damage to the Ice and Fire Demon Lord's Undead directly increased fivefold.

Moreover, the opponent's health is only one-fifth left, so the attacks that originally required ten thousand times now only require a few hundred times. It can be said that the difficulty has dropped dozens of times in an instant.

When Cecilia saw this scene, she no longer hid and directly used the red amplification skill. In an instant, all her attributes soared more than ten times.

But her blood volume also began to burn wildly.

And under this terrifying surge in strength, with every move, the health of the Ice and Fire Demon Lord Undead can be reduced by more than ten percent.

With just seven or eight sword strikes, the health of the Ice and Fire Demon Lord's undead was completely reduced to zero.

Unlike Ling Yan who would smash or even destroy the Saint King-level BOSS every time he killed it, there were only some wounds on the bones of the Ice and Fire Demon Lord's undead spirit.

But because its health was reduced to zero, it was considered completely dead.

"roar!!!!"

As his health dropped to zero, the frustrated Ice and Fire Demon Lord was finally able to move. He roared angrily towards the sky.

“Boom boom!!!”

The next moment, its huge body exploded under a mysterious force.

[Ding... Congratulations to the player, you've successfully killed the Ice and Fire Demon Lord's undead spirit! You've completed your reincarnation quest!]
