Old Mephisto Letting the Wolf into the House and Tony's Transformation

Just as Chen Tian and the Sentry were engaged in a great battle in an unknown star system.

Within the shattered dimensional rifts, several strangely shaped energies surged silently.

Space fragments, like shattered glass, floated around them, only to be crushed into finer dust by an invisible force.

This place was once a graveyard left after the Oblivion of a sub-dimensional entity; now it has become the most secretive dumping ground, the perfect place to discuss shady dealings.

"Tsk tsk tsk," a cloud of red mist, its interior churning with dark yellow lava, was the first to emit a piercing laugh, like sandpaper rubbing together—it was the projection of Mephisto, the Lord of Hell.

"Look at our high and mighty Deathstrike! She slipped away from the material world with her tail between her legs so fast! She even threw away her new toy to use as a punching bag! The 'outsider' intelligence I carefully packaged and delivered probably didn't even open the packaging before she suffered a huge defeat! Shameful, utterly shameful!"

The lava boiled violently at the core of his form, mimicking a gloating, manic posture.

"Enough, Mephisto!" Another massive mass of black mist, its interior shimmering with shattered, seven-colored light— Dormammu, the ruler of the Dark Dimension —let out a deep roar, causing fragments of the surrounding dimensions to fall in a tremor.

"Mocking death? You and I both know the power of that 'outsider'! He tore through my dimensional barrier like shredding a piece of waste paper! Every time he appears, the energy fluctuations emanating from him become even more terrifying... His weakness lies in not knowing our dimensional coordinates; otherwise, all of us... would be nothing more than lambs to the slaughter!"

The core of that black mist contracted violently, its seven-colored light flickering erratically, revealing an undisguised sense of dread.

"Hehehe!" A dark green mist twisted and turned, with serpentine black shadows moving rapidly within it, emitting a chilling, eerie laugh that sent Nightmare down one's spine.

"Dormammu, look at you, so terrified! The dark overlord who once devoured galaxies, now you only dare to cower in your shattered lair, trembling with fear? You don't even dare to repair the broken dimensions, constantly shifting coordinates like a frightened gopher?"

The deep green mist expanded arrogantly, almost touching Dormammu's black fog. "Odin has gone to his Valhalla, and the Ancient One has gone to the embrace of Eternity! Blue Planet, that tiny yet delicious planet, its dimensional barrier has never been so fragile! The position of the Sorcerer Supreme is still vacant! This is a window the universe has given us! If we don't take advantage of this moment to tear open the barrier and feast on the billions of vibrant, terrified, and nourishing souls on that planet, when will we?! Wait for that scoundrel Chen Tian to come back for a vacation and sunbathe?"

An aura of greed permeated the air.

"Fool!" Another crimson cloud of light surged violently, with eerie dark green runes flickering within it—a projection of the will of the ancient evil god Chthon.

His voice was cold and sharp, like a viper's hiss, "Tear open the dimensional barrier? You make it sound so easy! Nightmare, are you tired of living? With Chen Tian's vindictive, vicious, and ruthless nature, do you think he would let this piece of meat, Blue Planet, be completely unprepared? Believe me, the very first moment we tore open the passage and attempted to Descent, he had already pounced on us like a shark smelling blood, following our dimensional coordinates?"

The crimson mist churned violently, and the dark green runes became incredibly glaring.

"A trap! That's an absolutely massive, meticulously laid, deadly trap! Waiting for us 'foolish' dimensional lords to step right into it! Look at Dormammu!"

Chthon's light pointed to the cowering black mist. "More than a third of his vast Dark Dimension was burned into complete the Void by that fiend with that damned white flame! What is he doing now? Not repairing it, but frantically and relentlessly shifting the coordinates of his entire dimension like a stray dog! Why? Because he's afraid! He's afraid Chen Tian will follow the lingering coordinates from last time and directly storm into the core of his Dark Dimension! You want us to expose our coordinates? Nightmare, are you trying to drag everyone down with you?!"

"Hey, I almost forgot about you, the banished lord of the outer dimensions. The Chaos Magic you created has become a plaything for Chen Tian's lover. Are you angry? You only dare to rage in a powerless way? How shameful," Nightmare retorted.

Intense arguments echoed through the shattered dimensions, and various Negative Energies collided violently, making this land of death even more chaotic.

Lava boiled, colors shattered, snake shadows danced wildly, runes flickered... the chaotic energy turbulence nearly tore this fragile projection gathering apart.

"Quiet!"

A vast, inhuman idea, seemingly composed of billions of superimposed voices, swept across the entire shattered dimension in an instant, like a cosmic storm.

All the restless demonic projections froze instantly, and the collision of energy came to an abrupt halt.

At the core of the final emerald green mist, an enormous eyeball, covered in bloodshot veins and strange patterns, slowly rotated.

Cold, indifferent, bearing an age beyond time and a cruel understanding of everything— the Eye Demon, Shuma Gorash.

His gaze swept over all the demon god projections, and finally, as if it were a tangible entity, pierced through the chaotic dimensional barrier, gazing afar at that blue planet in the material universe.

That enormous eyeball clearly reflected the lonely silhouette of the Blue Planet in the vast universe, as well as the dimensional barrier surrounding it, which was as fragile as a cracked eggshell.

Deep within those enormous pupils, a pure, emotionless greed and cruelty quietly surfaced.

"The supreme power... has not yet returned." The Eye Demon's billions of overlapping thoughts roared once more, each word containing undeniable power. "The barrier... is as thin as a cicada's wing. Fear... spreads deep within billions of souls..."

The enormous eyeballs rolled, their icy gaze sweeping over every demon present.

"The feast of souls... has begun." The Eye Demon's will, like a cold iron hammer, struck the core of every demonic projection. "The time to reap... is now."

He paused, and the blood vessels in his enormous eyeball seemed to come alive, twitching slightly.

"Who... would willingly miss out?"

In the cracks of broken dimensions, there is a deathly silence.

Greed, fear, madness, scheming... countless emotions silently churn and battle within the silent projection.

The Eye Demon's words tore away all the high-sounding excuses, revealing the most naked temptation: the souls of billions of living beings! Right there! The barrier was more fragile than ever before!

The Guardian is weaker than ever before! Chen Tian, the only sword hanging over his head, is currently busy fighting fiercely with the golden sandbag left behind by Death in some unknown star system!

Of the many pawns that Chen Tian had once laid out on Blue Planet, very few remained. If he missed this opportunity, would he have another chance? The Eye Demon's gaze was like a cold searchlight, illuminating the most primal desires in the hearts of every demon god.

Mephisto's sinister laughter broke the silence. "Hehehe... Eye Demon is right, with such a grand feast before us, how can we be absent? But..."

The red light emanating from his lava core flickered eerily. "Chen Tian, wise all his life, made a foolish mistake! He thinks he's emptied Dewen County? I can open the 'door' to that place whenever I want! He can't even find the hinges!"

"Hehe!" The Nightmare's green mist churned excitedly, its snake-like shadows dancing wildly. "What a coincidence! You have the door, I have the key! The current United States President Ross... has long been my 'sleepwalker'! Otherwise, why do you think he'd go crazy throwing money at that 'Stellar Project'? Hehe, I even upgraded him a bit— the Hulk? Outdated! He's now the 'Red Giant'! Plenty of fuel for his rage! Just a gentle push from me..."

He let out a morbid screech, "Heh heh, Mephisto, the moment your artificial 'earthquake' goes off, my Red Giant will immediately push the panic to its peak! Chaos is the best coordinate signal!"

The dark green runes within the crimson mist of Chthon flickered coldly. "Since you all have cards... I'll add one too. Mordo, the Ancient One's 'good apprentice,' has long been planted with the seeds of darkness by me. The Darkhold in his hands is no mere decoration. He's currently 'cultivating' deeply... He can 'awaken' at any time and drive a few more nails into the Sorcerer Supreme's coffin lid! Coordinating with Nightmare's actions, disrupting the remaining power of Kamar-Taj, that's enough."

Dormammu's massive, multicolored black mist abruptly halted, then churned violently, revealing a deep sense of helplessness and frustration. "What the hell?! You... you bunch of old bastards!!"

The multicolored light within the black mist flickered wildly, revealing the intense turmoil within him. "So many landmines planted behind my back?! A president! A former disciple of the Sorcerer Supreme! And a Portal key?!" He suddenly froze, as if frantically searching through his inventory. "What about me?! What do I have?! Kaecilius?! Damn it... I'm dead!! This makes me look so stupid!!"

His black mist flared up like a punctured balloon, its multicolored light flashing wildly, the entire projection expanding and contracting erratically. The mighty ruler of the Dark Dimension was now like a primary school student who had forgotten his homework, so embarrassed at the Demon God Conference that he wanted to explode on the spot.

"Very good... the hidden piece... is in place."

Mephisto's lava core suddenly leaped up, his smugness almost overflowing. "Hehehe! Lord Eye Demon, just you wait and see! Leave the 'door' of Dewen County to me! I guarantee I'll help everyone thoroughly investigate the 'anti-theft lock' left by Chen Tian!" The red mist arrogantly expanded and churned.

"Hmph!", "Heh heh!", "Heh..."—several responses with different meanings rang out.

"Then..." The Eye Demon's overwhelming will carried a sense of dominance, "Mephisto... make your move."

"Yes, sir! Watch me!" Mephisto's light mist surged violently, with dark yellow lava boiling within. He seemed to be fully activating some interdimensional link. The light mist churned for a moment, then suddenly stilled.

The next second--

"Aaaaaah--!" A piercing scream that seemed to distort the dimensional fragments suddenly erupted from Mephisto's crimson mist!

Dead silence!

All the surging light and mist instantly froze! The Nightmare's serpentine shadow stood still in mid-air, Chthon's runes stopped flashing, and Dormammu's wildly flashing rainbow light came to a halt.

"Mephisto?!"

"Mephisto?!"

"What happened?!"

The demons were filled with a mixture of surprise and uncertainty.

Mephisto's luminous mist convulsed violently. "A trap!! Chen Tian's trap!! Right at the door!! Right where I just left the key!!"

"What is it?!" Chthon's voice was sharp and piercing.

"What is that?!" Nightmare's thoughts were filled with panic.

Mephisto's radiant mist convulsed even more violently, dimming the light of the lava core. After a long pause, he finally managed to squeeze out a sentence:

"Uh... a... a human wearing... dark green... heavy armor...?!"

A brief silence.

"Pshaw!" Chthon was the first to scoff disdainfully. "A human?! That's it? Mephisto, you're scared to death by a human?"

"Heh heh heh!" Nightmare instantly relaxed, letting out a piercing, eerie laugh. "A bug wearing Iron Man? Mephisto, you've really got guts!"

Even the frustrated Dormammu couldn't help himself; a few flashes of multicolored light flickered wildly within the black mist. Although he didn't utter a sound, his "Is this all you've got?" sentiment was exceptionally clear.

Mephisto's aura nearly exploded with rage, but the terrifying pressure emanating from that "human," which almost tore his mind apart, still lingered, leaving him speechless for a moment.

"Enough!" The Eye Demon's icy will silenced all the noise. "Begin!"

The enormous pupils swept over Mephisto, Nightmare, Chthon, and finally even glanced at Dormammu.

"Chaos... fear... coordinates illuminated... and I Descent."

A terrifying will, imbued with an all-consuming greed:

"I... want to see... just how strong this 'outsider' who can make even death retreat!!"

The Hell Dimension, a palace of crimson scorched earth.

Mephisto's enormous demonic form paced irritably, magma-like blood gushing beneath his lava-like skin. He tilted his grotesque head, growing increasingly furious.

"Damn it!" He spat fiercely, the lava sizzling as it hit the ground. "Scared out of your wits by Chen Tian? A mere human in a tin can dare to distract me and make me scream? Disgusting, utterly disgusting!"

He felt like a frightened little devil at the dimensional meeting, especially when he thought of Chthon's clear sneer and Nightmare's grating laughter, as well as Dormammu's barely suppressed contempt, a surge of evil fire rose within him.

"Disgrace! A disgrace to hell!" he roared, the sound shaking the stalagmites atop the palace, causing them to crumble. "Open the doors! Invade completely! Bring me the souls of those ants from Dewen County ..."

Before the words were even finished, the heavy palace doors were flung open with a loud bang!

A Felguard, his body billowing with sulfurous black smoke and half his wing bald, tumbled in, his voice trembling uncontrollably. "My... my lord! It's terrible! That... that Iron Man! He... he's broken in!!"

Mephisto's crimson pupils contracted sharply. "What the hell? Who broke in?!"

"The 'gate'! It's over at the border of Dewen County! That human in the dark green iron suit! He kills demons on sight! Brothers, we can't hold on, my lord!!"

Mephisto was stunned for a moment, then flew into a rage. "Useless! A bunch of useless trash! One human killed you all?! You have disgraced Hell!" He waved his hand, and the space in front of him instantly distorted, forming a scarlet light curtain.

The light screen displayed the scene near the Hell Gate in Dewen County.

The moment the image appeared, Mephisto's furious expression froze on his face.

Blood!

The dark red blood and burning limbs, characteristic of hell, almost completely covered the light screen!

At the center of the image, a figure is efficiently, ruthlessly, and almost mechanically slaughtering.

He was covered in heavy, dark green runic armor, with dangerous energy flashing at his joints. His orange goggles shone eerily in the dim, blood-red light. In his left hand, he gripped a thick shield with serrated edges, while in his right hand he wielded a strangely shaped red greatsword.

"Bang!" The greatsword cleaved a charging berserker into pieces, blood splattering everywhere!

"Sizzle--!" The chain serrations on the edge of the shield suddenly activated, emitting a piercing roar, and directly tore open the chest cavity of another demon, sending internal organs and bone fragments flying!

After killing those two, he didn't even look back. He Shield Saw and saw with his left hand and stabbed his greatsword into his back with lightning speed. At the same time, a rough-looking shotgun with a scorching barrel appeared out of thin air in his hand.

"Boom!!"

Kakkō erupted, and a low-level demon within a fan-shaped area was instantly blasted into dust!

Strangely, the corpses of the demons he killed with his own hands would emit wisps of scarlet energy, which, as if drawn by something, would quickly disappear into his dark green armor.

Mephisto's crimson eyes widened like saucers as he stared in disbelief:

The shotgun was still emitting wisps of smoke, but the next bullet was already automatically chambered.

The faint marks on the armor, inflicted by the claws of a high-ranking demon, were instantly repaired as if nothing had happened when the red light swept across them.

Even the charred areas on my arm that were just Hellfire are fading away rapidly!

"What the hell... what the hell?!" Mephisto was completely dumbfounded.

Killing monsters restores health and ammo? What kind of outrageous feature is this?!

He whirled around and roared at the trembling Felguard beside him, "Useless trash! Did you even ask who he is?! What kind of madman popped out of some nook and cranny?!"

The guard trembled with fear, nearly collapsing to the ground, his voice trembling with tears. "We... we asked! The men were terrified of being beaten, they asked us when they were begging for mercy..."

"Who the hell is he?!" Mephisto's roar shook the entire palace.

The guard, his neck hunched, answered in a voice a mixture of extreme fear and bewilderment:

"He... he said... my name is... DOOM!"

DOOM!

Dead silence!

Mephisto's ferocious face froze instantly, a mixture of rage, astonishment, bewilderment, and a hint of frustration at being tricked!

Doom??? Who is this???

The White House lawn in Washington, D.C.., has become a living hell.

"Roar--!"

A deafening roar tore through the air as Red Hulk —the monster that President Ross had transformed into—was even larger than the Hulk, his muscles bulging like dark red volcanic rock, each punch carrying a devastating shockwave.

The Falcon, which had just arrived, narrowly escaped the punch, its thrusters belching black smoke.

"Sam!" Captain America raised his shield to block, the Vibranium Shield humming as his feet dug two deep furrows in the ground. His star-spangled uniform was already torn in several places.

"This guy is even crazier Bruce!" Tony's voice came from under the visor. He hovered in mid-air, and laser cannons and micro-missiles kept bombarding Red Hulk, but only left shallow scorch marks on the other's skin.

His Eclipse Armor's left arm was twisted and deformed, sparks flying. "Friday! Damage report!"

The left arm transmission system has failed, the 'Eternity Core' repair speed has decreased, and the overall strength has fallen below the safety threshold of 40%. It is recommended to use the 'Archangel Protocol'.

"Damn it!" Tony spat. "Captain! This guy's weird, his strength is off the charts! I need to use 'Archangel' to deal with him."

Steve once again used his shield to block Red Hulk's heavy punch, using the force to retreat, and said in a deep voice, "Then use it! I want to wear the Cloth too!"

Tony's visor snapped open, revealing a maniacal grin. "No, Captain, I'll show you a 'new ability.'" He glanced at a non-existent wristwatch. "Hey, Sam, what time is it?"

Falcon, tumbling through the blast wave, yelled into the communicator, "Is this the time for discussion?! I'm being swatted like a fly in the air! Captain America has his Cloth, Tony has his suit, and all I have are these jet wings! Think of something quick!"

"11:55, Tony." Steve glanced at his watch, puzzled.

"Ha! Perfect timing!" Tony laughed. "Captain, go help Sam hold them off! Draw that big guy's attention! I'll be right there!"

Steve gave Tony a deep look and without hesitation said, "Sam! Get closer to me!" He hurled his shield, which struck Red Hulk on the back of the head with a loud thud, successfully drawing the monster's wrath.

Red Hulk abandoned Falcon and Tony in the air and roared as he charged toward Captain America.

Tony watched as Steve lured the target away, and his visor clicked shut. He quickly landed on a relatively intact patch of grass.

The nanotech armor on his body receded like a receding tide, merging into the 'Eternity Core' on his chest.

"Friday," Tony's voice trembled with suppressed excitement, "Activating the 'Sin Protocol.' It's time to try out my new 'toy'."

"Received, BOSS. Sin Protocol activated. Equipment drop authorization confirmed."

Before he could finish speaking, a faint whooshing sound came from the air. A black, briefcase-sized metal box fell precisely towards Tony.

The box disintegrated instantly just one meter above Tony's head, scattering and disappearing like a black sandstorm.

A palm-sized card with an unusual texture floated down and landed steadily in Tony's palm.

The card has a warm, smooth feel to it, and is definitely not metal or plastic. Etched on it is a lifelike golden lion's head, its mane wild like burning golden flames. Behind the lion's head, a sun ring, also outlined in golden light, exudes an invisible majesty.

At the same time--

Thump!!

Another, larger and heavier silver metal box crashed down beside Tony like a meteorite. The heavy impact cracked and collapsed the ground, creating a shallow crater. The box unlocked automatically and slid open to the sides.

A weapon lay quietly inside.

It was a giant axe with an extremely wild and heavy design! The handle was made of some kind of golden, unknown alloy, and its surface was covered with mysterious patterns; at the grip of the handle, there was a ring of spikes that resembled the sun, with smooth curves and ferocious spikes. Just by lying there still, it exuded a terrifying sharpness that could tear everything apart!

Tony looked down, his gaze burning as he stared at the Lion Sun Card in his hand. He took a deep breath and made a startling move.

He suddenly raised his hand and grabbed the Arc Reactor at his chest!

"Click!"

Tony removed the 'Eternity Core' and tossed it aside. The nanotech in the reactor automatically transformed into a small aircraft, spewing blue flames, and soared into the sky.

Without hesitation, Tony slammed the Lion Sun Card, which contained surging power, against his chest!

The moment the card touched his skin, it burst forth with a dazzling golden light like the sun! Countless golden energy lines spread from the card's center, instantly covering Tony's entire chest like a brand!

Tony tilted his head back and let out a roar that was a mixture of excruciating pain and power, the sound echoing across the battlefield:

"I am the sun!!"

Boom--!

Centered on Tony, a ring of pure, blazing golden energy erupted! Like a miniature sun rising from the ground!

Amidst the golden light, a brand new figure slowly straightened its body.
