Just as there was a fierce battle outside, inside the castle, the scorching atmosphere spread to every corner.

A sea of fire covered part of this room, and the figure of No. 33 and Shangguan Xia Yan were all shrouded in this sea of fire.

In the sea of fire, No. 33 stepped on Shangguan Xia Yan's body with one foot, and Shangguan Xia Yan, who was lying on the ground, was gradually losing the breath of life, and his body was becoming weaker and weaker.

"Hahahaha, I don't think I can do anything, a little martial king, how dare you play with fire in front of me?" No. 33 laughed unscrupulously, he himself was a martial emperor with fire attributes, he didn't expect Shangguan Xia Yan to actually release the Flame Bird Martial Spirit in front of him, all of this seemed so ridiculous to him.

"Shangguan ......" Hua Meinan sighed weakly, Lin Ying and Yun Ruoxi took advantage of this time to carry back Yang Zhaochan, who was already about to collapse.

"It's all my fault! If it weren't for me......" Yang Zhaochan saw Shangguan Xia Yan in the midst of the fire, and Zhu Liya and Hua Meinan were seriously injured, and felt guilty.

If it weren't for her insistence on finding Lin Tianyang's whereabouts, she wouldn't have been in such a situation now.

When she saw the group of people in front of her, all of whom ended up like this because of herself, Yang Zhaochan's eyes shed tears of remorse.

"Sister......" Zhu Liya raised her right hand weakly and wiped away the tears on Yang Zhaochan's face.

"Then it's your turn!" No. 33 walked out of the sea of fire, only to see that his whole body was in flames, and in the palm of his raised right hand, there was a bright flame flower, which contained extremely terrifying flame energy.

"What should I do......" Yueyue is still blessing her ability at the moment, which shows that Shangguan Xia Yan is not dead, but at this moment, the effect of her blessing is decaying, which also means that Shangguan Xia Yan's life breath is slowly disappearing at this moment.

"You guys, die!" No. 33 showed a hideous face, threw the flame flower in his hand to Yueyue and the others, Yueyue and the others closed their eyes in despair, waiting for death to come, and what came from their ears was the piercing laughter of No. 33.

When it was too late, everyone suddenly felt a low howl in the sea of fire, and the tone was hoarse, like a beast that had been sleeping for a long time and was being woken up.

Suddenly, I saw that the originally monstrous hot flames suddenly became more violent in an instant, frantically converging towards the middle of the sea of fire.

In the middle of the sea of fire, Shangguan Xia Yan, who was originally lying on the ground and dying, slowly stood up at this moment, kneeling on the ground on one knee, his whole body was covered by flames, and he couldn't see his face clearly.

Shangguan Xia Yan's life breath, which was about to disappear, suddenly rose violently at this moment, and with his breath, the entire sea of fire instantly collapsed, and in the blink of an eye, all converged into Shangguan Xia Yan's body.

For a moment, everyone looked at each other and looked at the scene in front of them in surprise.

Shangguan Xia Yan's aura continued to rise, not only the breath of life that was about to be lost, but also the violent power in his body.

Rank 9 Martial King ......

Rank 5 Martial Sect ......

Peak of the ninth-level martial sect......

First-class Martial Emperor ......

The pinnacle of the second-level Martial Emperor!

In an instant, Shangguan Xia Yan's figure full of flames suddenly jumped out, carrying the firelight, blocking in front of Yueyue and the others, raising a hand, and lightly caught the flame flower of No. 33.

"What?" Number 33's eyes widened, and he looked at the figure in front of him in surprise.

"Shangguan!" Yueyue and the others also exclaimed, because standing in front of them was Shangguan Xia Yan, who they thought was dead.

At this moment, Shangguan Xia Yan's entire body instantly turned red, as if he was wearing a crimson coat.

A crimson dragon's wings spread out behind him. Sharp white bones continued to grow from his body and spliced together into the skeleton of a dragon-like creature outside his body.

And on his chest, a flaming tattoo also appeared, his long red hair also turned into a burning flame, his eyes were blazing, and his body exuded a terrifying heat.

"You ......" Shangguan Xia Yan's voice was very hoarse, he raised his right hand, stretched out his index finger, pointed to No. 33, and said in a deep voice, "Come and die!" ”

Suddenly, a violent birdsong resounded throughout the castle, and even the people who were fighting outside could hear it clearly.

At the same time, a huge flame bird flew out from behind Shangguan Xia Yan and hovered in mid-air, waving its huge wings and letting out one terrifying chirp after another.

In this chirp, No. 33 seemed to feel the shock from the depths of his soul, and took a few steps back, and the flames on the Hell Flame Flower behind him actually dimmed.

"What kind of monster are you?" Number 33 was taken aback and asked in disbelief.

"Come and fight Lao Tzu!" Shangguan Xia Yan shouted angrily, and his figure suddenly moved, leaving a flame phantom in place.

Shangguan Xia Yan clenched his fist with his right hand, his fist was filled with flames, and a punch directly hit No. 33.

No. 33 was frightened by Shangguan Xia Yan's momentum for a while, and he didn't dare to fight, so he hurriedly moved his body and dodged Shangguan Xia Yan's punch.

Shangguan Xia Yan's punch directly hit the wall of the ancient castle, and suddenly, with a loud bang, the wall of the ancient castle was directly blasted out of a large hole with a diameter of more than three meters, and the big hole was still carrying burning flames.

"Give me death!" Shangguan Xia Yan retreated and turned around, and with a wave of his big hand in the void, a golden flame dragon appeared with his gesture, opening its teeth and claws, roaring and pounced on No. 33.

"Flame Flower!" After No. 33 stood still, he hurriedly raised his hands and condensed two flame flowers, and instantly put his hands together, fusing the two flame flowers together, forming a huge flame flower, which was thrown towards the golden flame dragon.

The original realm of No. 33 was only in the second-level Martial Emperor, although with his ability, he could pinch Shangguan Xia Yan to death at will.

But he never expected that Shangguan Xia Yan's body actually had a demon core that transformed the demon dragon

This demon core had long been perfectly fused with Shangguan Xia Yan, and it was able to absorb the surrounding heat and flames, thereby improving his cultivation.

After absorbing this entire sea of fire, coupled with the heat energy from the No. 33 Martial Soul Hell Flame Flower, Shangguan Xia Yan's realm at this moment had reached the peak of the terrifying second-level Martial Emperor!

It's even better than No. 33!

The golden flame dragon collided with the huge flame flower, and an earth-shattering explosion broke out in an instant, stirring up layer after layer of heat waves, directly overturning Yueyue and the others and pushing them out of the ancient castle.

The big explosion directly exploded the space where Shangguan Xia Yan and No. 33 were located, and in an instant, the entire ancient castle collapsed instantly, and a huge mushroom explosion floated into the sky.
