Wizard: Starting With the Knights Breathing Method Chapter 2800: 572: The Way of Spiritual Treasures, Nightmare’s Downfall!

While the King of the Underworld lacks such authority, this child possesses it.

To begin with, he can peer into past lives without restriction, requiring only the consumption of internal netherworld power. This allows Levi to preserve his remaining Rebirth Stones. Secondly, he possesses the ability to summon the descent of the Mother River, harnessing its vast power for purposes of healing, engagement, or retreat. It is clear this child was once the Nether Emperor in a former life and likely a direct scion of the Mother River itself, rather than a mere convert to the Underworld. Furthermore, Leon is capable of establishing his own Underworld legion, complete with the power to appoint his own King of the Underworld and various Netherworld Generals.

Many other powers belonging to the Nether Emperor are also at his disposal. As the little one gradually awakens and masters these gifts, his combat strength has already reached a level capable of suppressing middle-level 9 demons; his future potential is immense.

...

The Seventh Layer of Hell.

Dragon Fall Valley.

What was once a domain of the Undead has been transformed into a terrifying Demon Land. High above, an Abyss Well manifests slowly, and from its depths emerges the imposing figure of a mid-level 9 Sky Anger Demon. Following him is a retinue of over a dozen level 8 Commanders radiating powerful auras. Among them, standing prominently, is the Crow Feather Demon King, Victor!

Having fulfilled the Snake Mother's objective, he had retreated to the Abyss to regroup his former subordinates. Now, he has made a grand return, determined to establish his own sovereign kingdom amidst this era of chaos! One day, the name of the Crow Feather Demon King will be feared across all of Hell!

Buzz!

Suddenly, a massive Blood Sea surges forward, accompanied by a blurring crimson silhouette launching an assault. A blood-red greatsword cleaves through half of Dragon Fall Valley, while a whirlwind of countless blood-colored spirits rushes in to consume everything in sight.

The leader of the Sky Anger Demons wears a look of pure terror. "Damn it, it is the Dusk Palace Master! I will take you down with me!"

He rises in a fit of rage, only to see a golden world descending upon him. Atop a Golden Throne, a figure raises a hand, and the sound of a sword whistle pierces the very spirit. Nine-Ring Magic—Nine Sword!

The Sky Anger Demon falls, helpless as his form is shredded like thin noodles into a mess of Gore. As the Blood Sea recedes into stillness, a single demon remains standing between the earth and sky, staring up at the tall, black-armored swordsman. The figure on the throne looks down with a lazy gaze and chuckles softly.

"Crow Feather Demon King Victor?"

"How is it that you know my name?" Victor asks, frozen in place by fear.

Considering his rank as a mere commander, it made no sense for a powerhouse like the Dusk Palace Master to recognize him. In a demon hierarchy overflowing with experts, what did he truly signify? Levi looked at the demon with a hint of pity; he hadn't expected Victor to survive through three massive waves of war. His luck was truly remarkable.

"It ends here. You may die now."

With a clench of Levi's hand in the air, Victor's body erupts. His Demon Soul is promptly harvested by Leon. If he were ever to be reborn, he should think twice before leaving the Abyss again.

"We are leaving, Leon. Hell has become treacherous."

The Deep Red Eyes manifest on Levi's forehead, sensing a level-10 demon weaving a plot against him, perhaps even a trap. The timing is not right; he has no desire to engage a level-10 entity in a pointless, eternal struggle where neither side can truly slay the other.

"Let us go."

...

Ancient Banyan Fairyland.

"Master, I have retrieved Victor’s memories."

"Very well."

Levi accepts the new disc from Leon to examine its contents. Victor served as both a demon and a participant in the Council of Ten Thousand Clans. "The Snake Mother appears again... Previously, the Green Ghost mentioned this Ancient as well. It appears she is circulating that suspicious Nine-Headed Hell Snake Body Tempering Technique."

Setting the matter aside for the moment, Levi returns to his Cultivation. A month later, he consults his proficiency panel.

Levi—— Nine Realms of Descent: Twenty-stage (1/20 million).

...

The Nine Realms of Descent is a ninth-circle spell from the Nightmare Series, representing the pinnacle of Levi's research into dreams and illusions. It creates nine concentric, spiral-like dream dimensions, drawing upon the power of the Nightmare World to stabilize the casting. Once a victim is snared in the primary dream, they are led by subconscious cues toward a false "exit." By attempting to escape, they instead sink into the second realm—a deeper layer of the sea of consciousness.

Finding themselves still trapped, they will frantically hunt for a new "way out." Throughout this cycle, their logic fractures and their will is ground down until they reach the hopeless ninth layer. At this absolute basement of consciousness lies a lightless Deep Sea. Those trapped there will remain for eternity; if they cannot shatter the illusion, they are doomed to stay until their physical form perishes!

By developing this spell, Levi gained a fundamental grasp of how the Lost Monarch constructed his Nightmare Maze. He believes that upon reaching the legendary rank, he could build something comparable—not for cruel amusement, but to create a dedicated trial space. There, members could hone their spirit, resolve, and intellect.

Later, Levi utilized the Flame King Dragon to test the efficacy of the Nine Realms of Descent. Just as he predicted, the dim-witted dragon fell deeper and deeper into the trap. Before long, it was ensnared in the Ninth Realm, unable to find its way back. Others attempted various methods to wake the dragon, but failed; the technique functions as both an illusion and a curse. Only Levi can dispel it, unless a superior power breaks it through sheer force. Eventually, this magical sequence was added to the congress's archives.

...

Sometime later.

Sorren Continent.

Sky City.

The Daydreamer's eyes lit up as he stumbled upon the Nine Realms of Descent. With a single thought, his form dissolved as he departed for the Ancient Dragon Continent.
