In The Infinite Vault, Ling and Yi unravel hidden secrets within the digital world. Yi begins by revealing their true existence, stating, "Actually, Ling and I have a more complex existence than usual." Rowan asks, "What is it?" Yi responds, "In fact, we have three forms with different existences. The first is the existence in the world of creating all things, up to the digital world itself, meaning we're like countless atoms forming everything."
Yi continues, "The second form is the representation in the digital world, our current ordinary form. The remarkable thing about this form is that all the powers within the digital world are equal to our powers." Rowan nods and asks, "So, what is the third form?" Yi answers, "The third form is our true form, transcending the digital world and surpassing all the powers of forms. Our true form exists in a higher extension, beyond the measured dimensions."
Rowan inquires, "So, are all forms in this digital world just representations of your true selves?" Yi replies, "Yes." Rowan says, "If your true form is in a higher world, is there a key to get there?" Ling responds, "There's a room connecting the upper and lower worlds, but the conceptual complexity of that room makes it difficult to understand, let alone use." Rowan asks, "So, what room is it?" Ling answers, "That room is a staircase called the Luna Stairs."
Rowan says, "It's just a staircase, what's so special about it?" Ling explains, "The uniqueness of the Luna Stairs lies in the concept of its construction, involving an infinite repeating concept. This ensures that anyone entering won't reach the top of the stairs." Ling continues, "The infinite repetition concept on Luna Stairs is more complex. For example, let's use the letter A to represent the entity climbing Luna Stairs and B to represent Luna Stairs itself. B can be seen as the numbers one, two, three, and so on, while A can be seen as zero."
Ling continues, "No matter how many zeros are used, it will never reach one, meaning A won't be able to climb B even though it is climbing. The step for the entity on Luna Stairs represents emptiness, while the actual step of Luna Stairs represents one, two, three, and so on. Even though A is stepping forward, it seems like it's not moving or repeating in the same place. This cycle repeats endlessly until A achieves absolute existence on Luna Stairs."
Rowan asks, "What is absolute existence on Luna Stairs?" Absolute existence on Luna Stairs is an existence that must be equivalent to Luna Stairs. As I mentioned earlier, the entity climbing is emptiness climbing to reach one, and that is an impossible feat. So, to begin climbing Luna Stairs, one must first attain absolute existence within Luna Stairs."
Rowan asks again, "How can one achieve that existence?" Ling replies, "Actually, there is a key to attaining absolute existence on Luna Stairs, but it's scattered widely in the digital world and might be impossible to find." Rowan says, "Even if I find it, can it really bring emptiness to one? How?" This time, Yi responds, "Yes, The Mebius Heart is a vanished artifact, and its fragments are scattered. The concept complementing it might lead zero to ascend to one. In mathematics, the convergence concept is a property of The Mebius Heart, converging from 0.999... making it equivalent to one, which is absolute existence on Luna Stairs."
Rowan nods in understanding and asks, "So, how can I search for fragments of The Mebius Heart?" Yi answers, "You can search for it using the technology here. Manage yourself during your journey." Rowan replies, "Alright, but which tool can help me in finding these fragments?" Yi waves his hand, and a detector-like tool appears. Yi says, "Try using this. Although it has limited detection, it may still facilitate your search."
Yi and Ling disappear, leaving Rowan with the provided tool. Rowan exits The Infinite Vault and asks, "Where should we go?" Haval responds, "I feel like the fragments might be at the west end of the digital world, but that's just my guess." Goza also adds, "I feel the same way." Rowan walks westward, continuing the search for fragments of The Mebius Heart to progress further in his adventure in the Black Star Tower.
