The wall in front of him was shaking violently.

In the dark, dim corridors, hordes of nightmare creatures rushed by, rushing in the direction of the battlefield.

And in the shadows above the corridor beyond their sight, a palm-sized, inconspicuous black shadow crawled forward slowly but surely.

Its body was covered with hairy hairs, and its sharp claws gently grasped the gaps between the rocks, silently moving forward against the shadows on the ceiling.

The battle outside the castle was still fierce, as evidenced by the tremors of the walls and the rate at which the nightmare creatures were consumed.

This is already the fourth layer of the Nightmare Castle, and the nightmare creatures that have poured out of the various secret rooms and secret passages have all reached the third level. They're all horrible monsters that abuse one side on the outside. But here, it's just a consumable of a high-level war.

Mary wasn't as strong as Grim and could fight Kathling head-on. Therefore, once exposed, what awaits her must be the encirclement and suppression of powerful third-order nightmare creatures.

However, to Mary's great surprise, after infiltrating the third floor of the castle, her movements have never been smoother than ever. Although the castle was filled with a staggering number of nightmare creatures and terrifying magical traps, there seemed to be an invisible god in her brain.

What route should you take, where are the traps, when should you wait quietly, and when can you pass with confidence...... Under the guidance of that small voice, Mary made her way through levels and obstacles, bypassing lurking sentinels and traps, and reaching the fourth floor of the castle.

And if she hadn't sensed it wrong, the core of consciousness that had risen up and was engaged in a murderous soul battle with Grim had extended from here.

Not daring to spill her spiritual consciousness out of her body, let alone using her spiritual perception to scan everything around her, Mary gave full play to the characteristics of her bat demon transformation, disappeared all the way, carefully probed all the way, and finally climbed down the long corridor into a tall and majestic witchcraft hall.

The predecessor of this place may have been the core hall of Kesslinburg, and the central platform was densely clustered, and a black ball of light with a diameter of ten meters was suspended on it, connecting itself with the various areas of the castle through dark and deep magical light bands.

On the surface of the black ball, there are hundreds of strange magical images, all of which are real-time images transmitted back from all over the Nightmare Castle. Among them, in particular, the battle scenes in front of the ancient castle have the largest number, accounting for more than seventy percent of the magic images.

At this moment, a hazy and illusory humanoid light and shadow pestle stood in front of the central platform.

He looked up at the shifting images on the black ball, his hands dancing as if they were dancing. And under his control, the attack, defense, and the circulation of huge life energy in all parts of the castle are so well-founded and orderly.

Although the humanoid light and shadow were illusory, an extraordinarily bright halo of light flickered on his chest, faintly transmitting a soul fluctuation unique to a living body.

Kethling's Soul Core......

Mary's heart was so hot that she wanted to climb over the dome.

But as soon as her mind moved, the strange voice in her head came out.

"Be careful, that humanoid phantom is an impostor...... It's full of witchcraft traps, don't get even half a step close!"

Mary's body trembled slightly, and she immediately stopped.

is so far away, she is bound to be unable to take the initiative to sense the soul breath on the other party's body, so its authenticity is really not easy to judge.

But along the way, the voice in her head has helped her a lot, so Mary chose to believe the other party without hesitation.

"Then what should I do? Time is running out...... Mary asked silently in her heart, "Alice, if you know how to do it, just say it, don't pretend to be a ghost and trick me!"

The voice in his head paused, and finally removed the neutral, deep voice and replaced it with Alice's sweet, crisp voice.

"Hehe, I'm not afraid that you will hesitate whether I will hurt you!"

"Hmph, whether you will hurt me or not, I don't know. But I just need to know that you're not going to hurt Grim. So...... I believe you!" Mary said categorically.

Alice froze slightly, and sighed faintly: "You and Grim bumped into each other, and I don't know who was luckier............!

Mary didn't want to bother to think about and analyze the other party's complicated psychological changes, but closed her eyes and listened quietly to her plan's 'strategy'. In front of the powerful Witch of Fate, no guy will be able to keep or hide his secrets.

Even the newly-born Keslin!

As long as she wanted to, there was no secret she couldn't uncover. The difference was only in whether she was willing to pay the high price of obtaining these secrets.

With Alice, a cheating artifact, Mary, who has transformed into a petite bat, is like a divine help, weaving through a dense network of witchcraft traps and psionic threads. Her target was no longer the humanoid figure in the center of the hall, but the small chamber behind the hall hidden by a tall column.

The small secret room is only a dozen square meters in size, and the furnishings inside are extremely simple, with only a table and a chair.

And the long-missing wizard Fried sat silently on a wooden chair, with a pitch-black dagger stuck above his head, his eyes rolled white, his body trembled, and his mouth still let out a hoarse dry howl.

Obviously, that Kethling was still in the midst of a fierce soul 'fusion' with this Fried. If it weren't for the complete acquisition of the knowledge and memories in Fried's soul, I'm afraid this soul war would have ended long ago.

Mary cautiously climbed to the door of the chamber, but was blocked by a thin film of energy light. Despite the thin light film, it has an extremely amazing energy intensity, and it is quite difficult for an agile assassin like Mary to break through with a single blow.

And with it in the wayway, Mary couldn't sneak in silently.

Just when Mary was at a loss, Alice's voice rang out again.

"Get ready! I've already communicated to Grim that he'll unleash one of the most violent attacks in seven seconds. That attack would trigger the Nightmare Castle's energy, causing the light to disappear by a finger. You must grasp this time, and the first moment you rush in, you will use your soul mark to control the other party......"

"Got it!"

The connection of ideas is undoubtedly the fastest, and even the most complex and tangled ideas can be communicated with others hundreds or thousands of times in an instant.

Therefore, when the blow that shook the entire castle came, Mary instantly turned into a human form and took advantage of the moment the light film dissipated.

Her movements were swift, but this was Kathlin's nightmare territory. With the advantage of the home field, the slightest fluctuation of blood-colored energy was captured by Keslin, who was close at hand.

The witchcraft hall outside immediately roared with energy, and a terrifying spiritual coercion pushed over like a hill, threatening to crush this place to pieces.

In the secret room, the body of 'Fried' suddenly shook, instantly suppressed all the fighting, raised his head, and two dazzling strong lights lit up in the depths of his cloudy and dim pupils.

There wasn't much time left for Mary to react!

For top powerhouses like them, a thought in their minds is almost instantaneous, and the immediate reaction to a sudden encounter with an enemy is also an essential part of instinctive defense. There was no need to think about these things, and there was no need to hesitate, and almost at the moment when Mary's breath 'leaked', the entire Nightmare Castle and Kethling's counterattack was ready to go.

The film of energy light that had disappeared for a moment because the aftermath of the Great War affected the energy transmission reappeared. They spilled out of the doorway wall and quickly bridged towards the center. It may only take a moment and a half for them to reseal the door of the chamber.

At that time, the only way for the intruders to attack Xelin is to break the energy light film first.

Unfortunately, half an instant is also time.

For Mary, who is super agile, her opponent's quick reflexes are still nothing more than a comical slow motion in her eyes.

At the last moment, there was a banging of blood-colored energy at the door of the secret room, and it turned from a small bat demon form into a normal human form. The next moment, Mary's blood-colored figure had passed through the door of the chamber and appeared beside 'Fried'.

Two small tornadoes appeared between the two of them in an instant, and turned into terrifying wind vortex blades that wrapped around Mary's body. Pieces of its thin scales, as fast as a knife, the wind blade raged on the surface of its body like a drum knife array, even with the blood-colored energy protection body, Mary's body still appeared with countless small wounds, as if someone had been overtaken in an instant.

The Wind Vortex Blade was still expanding and dispersing, trying to block all of Mary's attack routes.

'Fried'' idea was simple, to use this terrifying instantaneous sorcery to force Mary off and try to buy herself some time to react. As long as it bends its fingers, no, as long as it is half-bent, it can mobilize the powerful power of the core of the ancient castle, protect this body, and let its core consciousness smoothly escape back to the central crystal.

Of course, in this way, it also means that it has to give up this high-level wizard soul of up to the 4th order, and it also means that it also gives up the opportunity to hit that terrifying threshold in the short term.

It's a pity, but it doesn't hesitate.

Therefore the soul is subject to human suffering, and it does not want to try again!

It's just a pity that the enemy it faces today is not only the legendary fire witch who is making waves outside the ancient castle, but also this super-sensitive blood witch who is also a 4th order. But it is the instigator behind the invisible background who really decides its fate - Alice, the leader of the Witches of Fate!

Mary didn't have the slightest intention of retreating or dodging, but she resisted the terrifying sorcery of the opponent's instantaneous counterattack, broke through the strangulation of the Wind Vortex Blade, pounced on the body of 'Fried', and bit him fiercely on the neck.

At the same time, a strange dazzling light poured into Fried's body, forcibly leaving the newly born Kethling in this body.

No............

'Fried' screamed, two voices evident in his hoarse roar.

But no matter how much it struggled and roared, its powerful vampire instinct still overshadowed its notological consciousness......
