With a terrifying grace, the Night King slipped into Ariel's body. Her skin shimmered in the moonlight, like snow on a winter day, with a faint silver glow. He was like a ghost, creeping in silently, and she was unaware of his coming.

However, this peaceful night does not belong only to the Night King. A cloud of silver light and shadow jumped out from the corner of the side, like a meteor piercing the silent night sky. It was Mitheus, his eyes glinting with a fiery glow like stars burning in the night. His figure became larger than usual, as if an elongated shadow appeared more slender and powerful in the moonlight. Clusters of hair emerged from his hands, like frost-soaked blades of grass, with distinct roots stretching out in the direction of the Night King.

Mitheus's nails also became unusually sharp, like steel that had been polished by time, and the cold light overflowed. His fingers were curled into sharp claws with a grim beauty. He lunged towards the Night King, like an enraged beast, unleashing the strongest challenge to his enemies.

Before the Night King could fully immerse himself from Ariel's body, he was interrupted by Mitheus' attack. His eyes widened as he looked at the familiar and unfamiliar Mitheus. Their bodies collided like two huge forces facing each other in the night sky. The air around them seemed to be frightened by their struggle, frozen in place.

They scuffled together like two whirlwinds of darkness whirling in the moonlight. Their movements are swift and powerful, each blow is like Thor's fury, and every dodge is like the dexterity of a cheetah. Their breaths were intertwined, like two torrents of ice and fire, impacting everything around them.

The Night King tried to break free from Ariel's body, but Mitheus clung to him, hair and nails tearing at his body like sharp weapons. The Night King's skin was instantly stained with blood, which had been cut by Mitheus' hair. His eyes flashed with rage, a frustration he had never felt before.

However, Mitheus was not satisfied with the current victory, and his body changed again. This time, his whole body was covered with a thick layer of hair, like a demon coming out of the abyss. His eyes became deep and wild, as if swallowing up all the light. He opened his bloody jaws and let out a deafening roar at the Night King.

Mitheus's closed eyes suddenly opened, shining like stars with an old, bright light. His body underwent subtle changes, his muscles tensed like beasts, and his sharp fingertips shimmered with a faint silver sheen. This was the power of the wolf king in his body, and that sleeping power now awakened, exuding a wild and dangerous aura.

The Night King was shocked by the sudden change, and he felt Ariel's body attack. Her skin grew cold and her blood burned. It was as if her body had become a battlefield in which he and Mitheus engaged in a fierce duel.

Their battles were fierce and protracted. The Night King tries to use Ariel's body to fight back, but Mitheus' power seems endless. His fur rushed towards the Night King like an army of horses. His nails were like quenched swords, cutting through the Night King's skin.

The Night King's heart was filled with anger and doubt. He couldn't understand why Mitheus had suddenly become so powerful, and he couldn't accept his defeat. His eyes gleamed with resentment, the anger of humiliation and the desire for victory.

However, despite the Night King's anger and confusion, Mitheus did not give him any respite. His attacks came incessantly, like a raging storm, unable to resist. Eventually, the Night King was knocked to the ground by a fierce blow from Mitheus.

He took a firm step forward, and every step seemed like a challenge to the bottom line of the night. His target, the Night King with the power of endless darkness, stood in front of him, watching his arrival with a cold eye. The Night King's eyes gleamed with mockery, as if he didn't care about his challenge.

Mitheus no longer hesitated, he stretched out his hand, and the power of the Wolf King instantly condensed into a silver beam of light, and struck at the Night King violently. The beam of light thundered through the air, with unrivaled power, as if it were about to tear the entire dark sky apart.

The Night King sneered, and with a flick of his finger, the dark power instantly condensed into a huge shadow barrier, blocking Mitheus's attack. The Shadow Barrier is like a bottomless dark abyss, engulfing all the silver beams.

In the vampire castle in the distance, feeling the power of Mitheus's awakened wolf king, those werewolves who were suppressed by vampires suddenly began to stir. They struggled to break through the vampires' chains. There was a determined glint in their eyes, which was the desire for freedom, but also the trust and expectation of Mitheus.

Mitheus ignored all of this, and he gave the Night King a deep look, his eyes shining with a challenge. He knew that the war had just begun. He needs more strength, more determination, to challenge this old enemy and save the bound werewolves.

He let out a low roar, and the power of the wolf king in his body surged again, turning into a huge silver wolf shadow and launching a fierce attack on the Night King. The wolf shadow was as fast as lightning, and the fierce attack caught the Night King a little off guard.

The Night King smiled coldly, and the dark power instantly condensed into a huge dark wolf shadow, fighting fiercely with the silver wolf shadow of Mitheus. Darkness and light collided in midair, making a roar.

The suppressed werewolves also began their counterattack. They broke free from the vampires' shackles and took on the form of werewolves, launching a fierce attack on the vampires. For a moment, the entire castle was plunged into a scuffle.

Mitheus felt the Night King's power slam down on him like a hammer, and his body was almost crushed. But instead of flinching, he struggled even harder. His heart was filled with hatred for his old enemies and love for his people, and this emotion turned into strength, allowing him to stand tall in the face of the Night King's attacks.

At this time, the liberated werewolves also joined the battle. They surrounded Mitheus and supported him with their loyalty and bravery. Their power echoes with that of Mitheus, forming a powerful storm of wolves.

The Night King watched the battle below, his eyes glinting with a grim light. He wasn't worried about Mitheus' resistance, because he knew that no matter how hard they tried, they couldn't overcome him. However, he did not expect that the power of the wolf king in Mitheus's body had been fully awakened.
