Start in Terra, immortal

The chair slowly rotated around, revealing faces that were unfamiliar to everyone in the laboratory.

"Long time no see, Strange, Christine," Rosso greeted the two with a smile.

"You know us? Who are you?" The two asked the question almost simultaneously. However, unlike Strange's simple confusion, Christine seemed unusually alert, her finger already rapidly clicking a button on the monitoring panel in her hand.

"Don't be nervous," Christine's gesture of waving for people naturally did not escape Rosso's notice. "If I had any ill intentions, you wouldn't have had the chance to wave those Illuminati members."

Upon hearing this, Christine's expression grew even more serious. This mysterious person who seemed to know about Universe 838 was clearly a visitor from another universe, just like the two imprisoned in the cell.

"Since you were able to bypass the Illuminati's security system and enter its most secret location without being detected, it seems our security system needs an upgrade."

"Since you were able to bypass the Illuminati's security system and enter its most secret location without being detected, it seems our security system needs an upgrade."

Christine joked helplessly, trying to ease the tension, but the wariness in her eyes did not lessen. "I was indeed calling my friends over, but only to remind them that a distinguished guest had arrived. I didn't mean anything else."

Having studied the multiverse for a long time, she knows better than others that there are many beings inside and outside the universe that are difficult for this universe to contend with, and this is clearly one of them.

Strange scrutinized Rosso through the transparent prison wall. He felt a strange sense of familiarity with the man before him, not in appearance, but in some deeper, underlying aura.

"Have we... met before?" he asked tentatively.

"In a sense, I guess so." Rosso didn't answer directly, but instead turned his gaze to the entrance of the room.

Almost at the same moment his gaze shifted, the alloy door of the room slid open silently, and several figures filed in.

Leading the group was Professor X, Charles Xavier, seated in a hovering wheelchair. Following closely behind were Black Bolt, Mr. Fantastic Reed Richards, Captain Marvel in Black, Captain Carter, and Baron Mordo.

They had clearly learned of the situation through Christine's emergency communications, and now they all looked at her with scrutiny and wariness.

"Looks like everyone's here." Rosso stood up from his chair, still relaxed. "Let me introduce myself. My name is Rosso. I'm here mainly because I've noticed that your universe is getting closer to another universe. Out of gratitude to a friend who keeps watch over time, I've come to resolve this issue."

Upon hearing this, everyone's expression changed. Clearly, they all knew what it meant for universes to be getting closer. Their universe's Strange had already told them the final outcome.

Professor X frowned slightly. His telepathic abilities seemed to encounter an invisible barrier with Rosso, making it impossible for him to read any useful information.

"Mr. Rosso, you seem to know a lot about our universe. But first, we need to confirm your purpose and your relationship with this Dr. Strange." His voice was gentle, yet carried an undeniable authority.

"Relationship?" Rosso glanced at Strange in the cell and smiled.

"So it's like... a creditor and debtor relationship? I did him a small favor, and he promised to do something for me. Of course, it's a different version of him."

As for my purpose, as I just stated, I'm here to resolve the issue of this universe being unusually close to another universe.

"The other him?" Mr. Fantastic Reed keenly grasped the key point.

"You mean Strange from another universe? You had contact with him and reached some kind of agreement? Then, is the 'friend' you mentioned also related to him?"

"My friend," Rosso looked into the void, as if he could see through dimensions to the end of time, "is called Loki, and he's currently sitting on a rather uncomfortable 'throne,' guarding all timelines."

I promised to keep an eye out for some 'variables' for him, and in exchange, he gave me some coordinates about the Fallen Leaf Universe. Dealing with your problems is just a way of repaying a favor, since the stability of your universe is also related to the integrity of the timeline.

"Loki? That god of mischief?" Baron Mordo scoffed, clearly distrusting the name.

"Yes and no." Rosso didn't explain further and changed the subject directly. "Seeing that you didn't express any doubt when you heard that space was approaching, I think you know the seriousness of the matter."

"Wait, can someone explain this to me?" Strange, still locked in his cell, was completely bewildered. "I can barely understand the others, but what does 'the universe is unusually close' mean?"

The one who answered his questions was Baron Mordo, the new Sorcerer Supreme of Kamar-Taj.

"Like you, Stephen prefers to be alone. While we are all uniting to fight Thanos, Stephen is pinning his hopes on the multiverse."

He paused, as if reminiscing: "Through the dream journeys of the Dark Book, he continually influenced the multiverse. Ultimately, he told us that he caused the collision of universes, killing everyone in that universe."

After saying that, Mordo fell silent, but Black Shock took over: "The irony is that the Dark Book didn't help us defeat Thanos; instead, the Book of Vishanti played a crucial role. And Stephen, out of guilt, willingly chose to die at Black Bolt's mouth."

"The Dark Book? Dreamwalking?" Strange muttered to himself, then suddenly, as if he had grasped something, "Wanda! She dreamwalked into this universe and has already triggered a collision between two universes?"

"Wanda? She's the possessor of the Dark Book from your universe?" Professor Charles immediately realized. "Quickly, investigate Wanda in our universe!"

"No need to investigate!" Seeing that they had realized what was happening, Rosso, who had been watching the show for a while, interrupted them. "She's already here."

Then, he extended a finger, and two beams of golden light shot from his fingertip, striking the transparent walls of the two cells. Without making a sound, the special material formed from the sands of Vishandi instantly turned into dust, falling to the ground with a whoosh.

"Go, Strange!" Rosso clasped his hands together with a crisp sound. "I'm rooting for you!" He then returned to his seat, leaning back as if watching a show.

While it was called "watching a show," it truly was. After all, Rosso had already sent a message to Strange in another universe via the communication array, and once he received the message, Rosso wanted to see how the Illuminati would handle the situation.

The message read: "You're going to deliver it? Come stop you!"

As for cosmic collisions, there's absolutely no need to worry; the solution is quite simple.

Let alone the fact that there is still a long time before the actual collision, even a moment before the collision, Rosso is fully capable of stopping both universes. There is still plenty of time, so watching the show is more important!
