At this moment, Wang Yan was holding the Darkhold, looking at Mephisto.
Mephisto's face was dark and angry as he glared at Wang Yan.
He wouldn't have returned after barely recovering if the Darkhold weren't so important to him.
"Sorcerer, we started out as enemies but became acquainted through our fight. If you return my book, I swear by the Five Great Beings that I will never come to Earth again!"
Mephisto said.
His words couldn't be trusted as a devil who thrives on schemes and tricks. Swearing by the Five Great Beings was meaningless; deceiving them would be easy for him.
No matter how powerful the Five Great Beings were, in his domain, they were nothing.
He only wanted the Darkhold back, willing to pay any price. If Wang Yan agreed, he would absorb the Darkhold's power and return to plunge Earth into darkness.
Of course, he said this without realizing Eternity was watching him; otherwise, he wouldn't dare speak so boldly.
But Wang Yan naturally didn't believe him.
"Do you think such an oath is useful?"
Wang Yan didn't believe anyone would be bound by an oath, especially someone as terrifying as Mephisto!
In Wang Yan's hand, the Vishanti's Holy Sword glowed with a powerful purple light, ready for battle.
Mephisto frowned.
"Foolish mortal, do you think I am the same as before?"
Mephisto's appearance had changed, now resembling a demon with two horns on his forehead, exuding evil.
Dark energy swirled around him, and a vision of a world of lava and flames appeared behind him.
A substantial oppressive force spread, making it difficult for even Wanda and Vision, protected by the Shield of Seraphim, to stand.
This pressure was spiritual; they couldn't resist it.
"Sorcerer, do you still think you can fight me? Do you believe you can win?"
With hell's power backing him, Mephisto was supremely confident, no longer fearing Wang Yan.
Even the Five Great Beings wouldn't easily stand against him now.
With his current power, not even the Ancient One could resist.
Wang Yan felt a strong oppressive force; even his Infinity Stones radiated immense power in response.
Though he didn't have all the Infinity Stones, the power he could command was unimaginable.
The combined power of the Infinity Stones could grant wishes, and mastering them granted limitless power.
While many sought this power, few could genuinely wield it.
Wang Yan swung his sword, the power of the Power Stone converging and sweeping toward Mephisto.
Mephisto's powerful force field surrounded him, blocking the attack.
This was Mephisto's collective power.
Even a casual attack couldn't break his force field.
Hiss!
The sword's power dissipated upon nearing Mephisto, and Wang Yan's attack was nullified.
"How is this possible?"
Vision and Wanda were shocked.
They knew Mephisto was powerful but didn't expect Wang Yan's attack to disappear before reaching him.
Mephisto's full power was far beyond their expectations.
"I didn't expect you to be even stronger than I thought!"
Wang Yan wasn't too surprised, speaking calmly.
Few defenses could withstand the power of the Power Stone.
But Mephisto hadn't even used his entire defense, yet Wang Yan's attack couldn't break through.
"Now, do you understand what you're facing?"
Seeing Wang Yan unable to break his force field, Mephisto felt relieved.
Earlier, he had been powerless, but now, with his whole strength and hell's power, he felt confident he could kill Wang Yan and satisfy his vengeance.
Just then, Wang Yan threw a thin, transparent blade.
The blade looked fragile compared to the mighty purple sword that couldn't break Mephisto's force field.
Hiss!
Splat!
But to Mephisto's disbelief, the blade tore through his force field and pierced his body.
Mephisto's proud expression turned to shock.
The blade that had seemed insignificant now broke through his powerful force field and body.
Wanda and Vision were equally shocked.
The transformation was sudden.
The Watcher frowned, puzzled by how the previously ineffective attacks now succeeded.
Having seen countless strong beings, he hadn't anticipated such a rapid change from the sorcerer.
Only Eternity understood.
"The Cosmic Blade, interesting!"
As a powerful deity, Eternity could see through Wang Yan's magic.
Using cosmic-level space blades, even Eternity was amazed.
He could control the universe but couldn't easily wield its sharpness.
The Cosmic Blade's threat was evident.
During Wang Yan's battle with Annihilus, he used this magic, which had even posed a threat to Annihilus.
The power's strength was evident.
But why could this young sorcerer use such power?
Eternity was even more shocked by what happened next.
Wang Yan had no interest in how others felt. Having struck Mephisto, he wouldn't waste the opportunity.
"Explode!"
Wang Yan said calmly.
The blade inside Mephisto exploded, unleashing a terrifying destructive force.
The powerful energy began destroying Mephisto's body.
Mephisto's body collapsed in an instant.
This destructive power was hard to resist, even for gods. Wang Yan sensed that Mephisto wasn't dead, despite his body's collapse.
Mephisto's soul power remained.
As the Hell Lord, he had more than just physical power.
"What a terrifying destructive force, like a cosmic storm!"
The Watcher was shocked.
He had thought the blade was merely sharp, but its explosive power was immense.
Eternity took a deep breath. The blade's sharpness and explosive power were a threat to their existence.
But Hell Lords were exceptional; they didn't readily reveal their proper forms, even if seemingly killed.
Eternity watched calmly, smiling slightly: "It's getting more interesting!"
As Eternity spoke, Mephisto's scattered body parts turned into smoke.
The smoke reformed into Mephisto.
Mephisto reappeared, saying, "Your power is unique, but you can't kill me!"
Wang Yan frowned slightly: "As expected of a Hell Lord, quite special!"
With hell's backing, Mephisto wouldn't die quickly. Even if his body were destroyed, hell's power would restore him.
If they fought in hell, no one could genuinely kill Mephisto.
Though Mephisto was more potent than before, he wasn't as powerful as in hell.
"With hell's power, you won't die, but you won't get your book back either!"
Wang Yan sneered.
Mephisto, who had been pleased, now felt his mood sour.
He trembled with anger.
"Kid, you're the first human to anger me!"
"Even if the Ancient One comes, you will die today!"
Mephisto said furiously, black energy swirling around him...
