Start in Terra, immortal

Silence fell over the living room as the portal disappeared.

After a brief silence, America raised her head, her gaze shifting between Rosso and Black Strange, before finally mustering her courage to look at Rosso.

"Mr. Rosso," her voice was soft but clear, "I...I have a request."

Rosso raised an eyebrow, seemingly surprised: "Oh? What request? You want Strange to give you extra training?"

America shook her head, her hands unconsciously clenching into fists. "No. I... I want to join the spirit world."

Upon hearing this, even the Black Strange figure standing nearby showed a look of surprise. He looked at America: "America, do you know what you're saying? The Spirit World is…"

"I know!" America interrupted him, her eyes resolute. "I know the spirit world is Mr. Rosso's world, the place where souls reside. I also know that I am a living person now, not a soul."

She took a deep breath and continued, "But I saw Ms. Christine there. She looked... peaceful and happy. And Mr. Rosso said that the spirit world is still growing, that it needs 'nourishment,' and that it needs residents?"

She looked at Rosso: "My ability is special, and it's dangerous. I'm afraid it will get out of control, and I'm also afraid of being targeted by something like that witch again."

No matter which universe I'm in, I've always felt like an outsider, a nuisance. But here... after following Dr. Strange and seeing what you've done, I feel that perhaps there's a place that can truly accept me and allow me to use my abilities to do something meaningful.

The spirit world sounds like that kind of place. It exists independently of the multiverse and has its own rules.

If I could become a part of the spirit world, I wouldn't have to wander between universes, and perhaps I could find a true 'home'.

I can use my abilities to help maintain the spirit world and to help souls like Ms. Christine who need help.

After America finished speaking, she looked at Rosso somewhat nervously, waiting for his response.

Black Strange frowned slightly. He understood America's feelings; this girl had experienced too much hardship and fear. But he also knew that the spirit world was no ordinary place.

"America, the spirit world is, after all, a world for the dead, and its rules may not be suitable for the long-term existence of living beings."

"Hmm?" Rosso glanced at the black oddity. "You think you know everything? Who said the spirit world isn't suitable for the living?"

Then, he looked at America with interest: "You want to truly join the spirit world, not as a guest, nor as a temporary refugee?"

America nodded vigorously: "Yes! I want to be a part of the spirit world. I can study, I can work, I can use my abilities to help! As long as... as long as there's a place where I can stay safely, where I won't hurt others or be hurt by others."

Rosso stroked his chin, pondering for a moment. "Your ability to traverse the multiverse is indeed unique. For the spirit world, which may need to establish connections with more worlds in the future, this ability has potential value. However…"

He then changed the subject: "I still need to explain to you first that once you join the spirit world, you will be deeply bound to the spirit world, or rather, to me."

Whether you will be able to traverse the universe after joining the spirit world, I don't know. Furthermore, at that time, you will face many of the same crises and risks that the spirit world faces, which are no easier than those within this multiverse system.

"If I lose my powers, will I die?" America asked anxiously.

"No, that won't happen. You can't die in the Spirit Realm," Rosso pointed at Strange, "Then I'll hand over the title of Lord of the Spirit Realm to him!"

"Since we won't die, isn't that a good thing? It's much better than constantly running away, having our abilities stripped away by countless powerful beings, or having our abilities go out of control and kill others!"

As for other risks and crises, I'm not afraid!

Rosso looked at Strange: "What do you think, Strange? She's your student."

Black Strange paused for a moment, then slowly said, "Her abilities do indeed need further development and guidance in a controlled and safe environment. If the spirit world could handle people like that witch who are drawn to her abilities..."

As he spoke, he noticed Rosso's gaze directed at him again, and coughed lightly.

"Ahem, the spirit world is indeed a good home for you, America!"

"But there's no need to worry too much. You're unlikely to provoke anyone stronger than me." Rosso nodded. "How about this, America, I can give you a 'trial period'."

"Trial period?" America's eyes lit up.

"That's right," Rosso explained. "You can learn control abilities from Strange in the spirit world, and at the same time, you can observe and understand the spirit world."

During this period, you will need to complete some designated tasks and, under my supervision, use your abilities to conduct some simple intercosmic matter or information transfer tests.

If you feel you don't like life in the spirit world, I allow you the opportunity to return to this multicultural system.

America nodded vigorously, her eyes filled with determination: "I understand! I'm willing to undergo the trial period, and I will work hard to prove my worth!"

"Very good." Rosso nodded in satisfaction. "Then it's settled. After I finish what I'm doing, I'll take you to the spirit world to 'report for duty'."

"Then, let's go." Rosso said no more, gathered energy in his hand, and with a gentle wave, the barrier of the universe shattered like glass.

He enveloped the two of them with an energy shield and broke through the raging turbulence to rush inside.

In the bizarre and fantastical space that America found so surreal, her mouth agape: "This... this is how you travel through the universe?" Then, staring at her hands, she asked, "Can I do this too?"

While maintaining the shield, Rosso glanced at her and said, "Theoretically, as long as your energy control precision and total amount are sufficient, and you can accurately locate the coordinates and 'frequency' of the target universe, you can do it too."

However, this requires extensive practice and a deep understanding of the nature of space. Your current abilities are more like 'instinct' and 'talent'; directly tearing through space is too early and too dangerous for you.”

Black Oddity added from the side, "Your portal is a safer and more efficient method. It seems to directly utilize some kind of 'network' within the multiverse itself, consuming less resources and with more precise positioning."

Forcibly tearing through space is like smashing a wall with brute force; while direct, it consumes enormous energy and can easily cause instability in the spatial structure, potentially leading to dangerous narrow spaces.

America nodded as if she understood, but her longing and curiosity for power only intensified.

As she watched Rosso effortlessly manipulate energy, carving out a stable passage through the turbulent cracks of the universe, she secretly made up her mind.

"I definitely want to be this cool someday!"
