Start in Terra, immortal

Rosso paused, his gaze returning to the unconscious Wanda: "Chaos magic originates from the ancient demon god Cynthian. Even if only a fragment of his power resides within this girl, it's enough to give her soul a certain resistance, allowing her to withstand my initial 'awakening'... However, that's all."

After hearing this, Bucky's gun was pointed at Rosso, but his finger on the trigger trembled slightly: "Who exactly are you? An alien? A god? Or... a raider from another dimension?"

Having witnessed the tragic deaths of his teammates and the twisted "feeding" of Wanda by Vision, he is filled with suspicion and distrust towards all supernatural beings.

"A predator from another dimension?" Rosso savored the word, then smiled slightly. "From the perspective of this universe, your description isn't wrong—I could indeed be considered a predator."

He raised his hand, palm up, and a faint light appeared, quickly unfolding into a complex three-dimensional array of runes, within which flowed a stream of energy interwoven with pale and light gold.

"The souls of those zombies have been sent to a more suitable place to 'settle' them, a place that can purify their souls. As for this host of chaotic magic..."

Rosso looked at Vision: "Although her soul was not severely corrupted and assimilated, given the depth of her entanglement with Sithon, forcibly purifying her would only destroy the core of her consciousness. I temporarily severed the connection between her magical activity and her zombie body, putting her into a state of dormancy, but the root problem has not been solved."

A rare expression of pain appeared on Vision's mechanical face: "Is...is there a way to truly save her? Not like I did before..."

"Yes," Rosso's answer was surprisingly affirmative, "but it will come at a price, and not now. The immediate priority is to address the planet's 'ailments'."

He turned around, his gaze seemingly piercing through the thick walls of the base, looking into the distance: "Your original plan was to take the Mind Stone to Wakanda and send healing frequencies across the globe, right?"

"How did you know?" Okoye blurted out, then realized that the other party's abilities had already exceeded common sense.

"That's no longer necessary." Rosso's voice turned cold. "What awaits you in Wakanda now is the same infected Mad Titan—Thanos. He wears the Infinity Gauntlet studded with five Infinity Stones, and his army is far larger than you can imagine. If you go, you'll only be walking into a trap."

"Infinity Stones? What are those?" Most of the survivors knew nothing about them.

Rosso pointed to Vision's forehead: "He should know."

Vision touched the gem on his forehead and explained, "I only know that I was born from the Mind Stone, but I don't know what these gems specifically mean."

Seeing that no one knew the power of the Infinity Stones, Rosso decided to give a more intuitive explanation.

"Simply put, they are the physical manifestations of six universal rules. Once you collect them all, any wish can be granted."

Like being doused with ice water, the survivors instantly felt a chill run down their spines. Their last hope, Wakanda, had already fallen into enemy hands?

"Then... what should we do?" Peter's voice was hoarse. The successive blows and this despairing truth began to shake even the young hero's resilience.

Rosso didn't answer immediately. He looked around the dilapidated base and at the wounded survivors before him, their faith shattered, and slowly began to speak:

"Two choices."

"First, stay. I deliberately avoided uninfected people when clearing out the zombies. You normal people can continue to live and multiply in this shattered world after the cleanup is over."

"Second, leave. Leave Earth, even leave this universe. I said before that this universe will eventually perish, although you may not live to see that day."

"You know we have no way to leave the universe," Bucky said, lowering his gun. "The fact that you specifically mentioned leaving means you have a way, right?"

Rosso's lips curled into a slight smile, his tone playful: "I told you, your judgment of me before wasn't wrong. I am indeed a plunderer from another dimension—my purpose is to harvest the souls of the entire dimension."

Bucky's lips twitched slightly. "I take back what I said earlier. Please forgive my offense." He knew in his heart that if the person before him had truly come for this reason, no one could stop him. There was no need for him to play along with them here.

"I have taken the souls of all the zombies outside into my world. There, I can easily erase the pollution from their souls, freeing them from this state of being neither alive nor dead, and allowing them to live again as 'humans'."

Rosso turned to T'Challa: "Including your people, the souls of Wakanda."

Then he looked at Vision: "Including your lover who is tormented by both chaos and the virus—I can strip away the contamination while preserving her true self."

Finally, his gaze swept over everyone: "Everyone you care about can find a new life there."

The base fell into a deathly silence, with only the faint hissing of the ventilation ducts and the heavy, heaving breathing of the people.

Bucky slowly turned his head and exchanged a glance with Okoye.

Dr. Banner took a deep breath, adjusted his glasses, and his gaze gradually hardened.

Peter Parker clenched his fists and pressed his lips into a straight line.

For the first time, the Mind Gem on Vision's forehead emitted a steady, gentle yet firm glow.

T'Challa leaned against Okoye, his back still ramrod straight despite losing a leg. He spoke slowly, his voice hoarse but clear:

"As the King of Wakanda, I will never abandon my people."

“Even if there’s an abyss ahead,” Bucky continued, picking up the shield that had originally belonged to Steve Rogers, “we have to see it for ourselves.”

Peter let out a long breath and adjusted the spider web projector: "Aunt May, MJ... I will find you. Count me in."

Banner nodded: "Hulk... this time, please really help me."

Vision floated into the glass wall imprisoning Wanda, gently stroking her zombified face, and whispered, "I will find a way to save you, Wanda. This time, I won't choose the wrong way."

Rosso looked at the people who had made their choices, a barely perceptible smile flashing across his face.

"Very well. So... who would like to be the first explorer and take a tour of my spirit world?"

"I'll go first!"

Scott, supported by the cloak, floated slowly to Rosso's face from inside the jar.

"As you can all see, all I have left is this head."

His voice was more serious than ever before, even trembling slightly, "Even if it really is a den of dragons and tigers over there, the worst outcome is just losing my head... Let me go, please, guys."

This usually somewhat frivolous "canned head" was now unusually teary-eyed, his expression full of sincerity.

"This disaster started because of us... and we should bear the consequences. I believe that if Hope were still alive, she would have made the same choice."
