"In another world, you failed in the war to annihilate Kazdel, and at the cost of your life, you met Theresa, and together you founded an organization called Babel—"

"?"

"You awakened the Prophet from his sarcophagus for the Tower of Babel, but Theresa developed a technique to reversely decompress the Originium. Therefore, the Prophet considered you a threat to the Originium Project, so he chose to backstab Theresa, and then had his memory erased by Theresa before she died—"

"Wait a minute! What did you say?"

"You placed the amnesiac prophet back into the sarcophagus in Chernobog. You and Amiya established a new medical company, Rhodes Island. After a while, Amiya chose to reawaken the prophet—or rather, the doctor."

“????” Kal’tsit really couldn’t hold it in any longer. “Alright, that’s enough! Stop talking! I believe it! Isn’t that enough for me to believe it?”

"Hey... we just got to the exciting part—" Noah shrugged regretfully, "Do you believe it this time?"

Kal'tsit took a deep breath, her fingers unconsciously tapping the edge of the medical kit. She needed time to digest the information about the parallel world Noah had revealed. Those stories about "another self" sounded too absurd, yet inexplicably... plausible? As a rigorous scientist, she instinctively rejected such unsubstantiated hypotheses. However, the blue crystal on Noah's chest and the abilities he had just demonstrated forced her to reassess the current situation.

“So,” Kal’tsit finally said, her voice lower than usual, “do you think this kind of…interdimensional information exchange is possible?” She studiously avoided the word “parallel worlds,” as if that would make the concept sound less crazy.

Noah could feel Amiya's consciousness trembling gently within her, as if she wanted to join the discussion but was restraining herself. She placed her palm over the crystal on her chest, a gesture that had become a habit when communicating with Amiya. "It's not just possible, it's necessary."

"It sounds great in theory," Kel'tsit interrupted, "but what about in practice? How do you ensure the accuracy of information transmission? How do you avoid information pollution? Not to mention..." She suddenly paused, her brow furrowed. "Wait, you said you can 'see' the branching points of world lines?"

[Dr. Kal'tsit always grasps the key points.] Amiya's consciousness chuckled in Noya's mind.

Noah nodded slightly. "It's like... watching a pun on branching options?" She tried to use a metaphor Kel'tsit could understand. "I can see the branches that arise from each decision, but I can't change what has already happened. Information exchange must take place at specific 'nodes,' just like..." She thought for a more appropriate description, "like building a sluice gate at the fork of a river."

Kal'tsit's expression became thoughtful. She was familiar with the concept of "nodes" - in essence, many results are based on choices, and what Noah said was that she could see the divergent routes that might appear after making a choice.

"I need more evidence," Kal'tsit finally said, her tone much softer than before. "It's not that I don't trust you, but a plan of this scale..."

"I understand." Noah breathed a sigh of relief. She could sense that Kal'tsit's attitude was changing. "Actually, I have a more direct way to prove it."

Noah nodded and put his hand on Kal'tsit's shoulder. In her puzzled eyes, Noah showed a harmless expression - why don't I take you to another world line?

"?"

Kal'tsit's eyes widened instantly, and before she could object, the next second, the room was empty.

The next moment, Noah and Kal'tsit appeared in an office in the Terran Federation building. Interdimensional hopping, one of the Observer's abilities, was still a relatively unskilled skill, but simply transporting a single person was easy enough. However, Kal'tsit was different. This was her first time experiencing dimensional hopping, and she resisted the intense dizziness and sense of spatial dislocation, not vomiting out of control. This was a remarkable display of willpower.

"Where...is this?"

"The Terra Federation office—" Noya replied. In this world, she had changed into her specially customized Terra Federation uniform again. "Welcome to the Terra Federation, Dr. Kel'tsit."

Noah supported Kelsey and was about to explain the situation to her, but the next moment, the door was pushed open -

"Noah—there's a new one here in Rhodes Island..."

The person who entered was stunned when she saw the situation inside the house. After all... she saw another... herself here?
