Legend has it that by traversing the perilous Broken Star Sea and the extremely harsh Storm Belt, one can glimpse the deep Ocean, also known as the "Endless Ocean" Phorcys, where even the highest mountain peak turned upside down cannot touch the seafloor.
No one has set foot there yet, but according to my calculations, that Ocean’s territory should occupy exactly half of this spherical world’s area. We had just started on the Stormy Sea Route and hadn’t delved into the Storm Belt, but it was already clear that only the Legendary Battleship could pass through safely.
Our original plan was to gather the remaining compasses, recruit adventurers eager to explore unknown worlds, and then have the ’Theseus’ undergo a true Extraordinary Transformation before embarking on this journey....."
Some of what Aiven already knew, and some he didn’t, were very detailed. From this, it was also apparent that this Great Wizard was evidently... henpecked.
The subsequent events unfolded naturally.
Having been prepared to explore the "Endless Ocean," Aiven agreed to join the invitation, not as a crew member of this "Theseus," but as a collaborator.
After being promoted to a Tier 3 High-Rank Wizard and hearing about the horrors of the "Endless Ocean" from him, Aiven was ready to initiate his shipbuilding plan!
He even casually suggested some advice to Jelos upon seeing eight ships in the captain’s cabin, reassembled with decayed materials, regarding the fundamental issue of "Theseus’ Ship."
That is: after being replaced eight times, is the ship still the original "Theseus’ Ship" underfoot?
Aiven felt that the opposite’s "Theseus School" was somewhat similar to his revised "Life Tree."
In seven years, the cells in a human body renew once, but no one would think that they are a different person seven years later.
Therefore.
The basis for identifying an entity as itself is not the elements composing the entity but the internal structure of the entity—the relationship between the elements and the space-time continuity of the entity!
In quantum mechanics, there is a "Principle of Identity," which states that particles of the same class are inherently indistinguishable. The elements composing the body have been replaced, but the particles of the same class are exactly the same, with no difference in properties. Replace the hydrogen atom in your body with another hydrogen atom, and your body’s properties remain unchanged.
If we smash a car into pieces and forge it into metal blocks, then make a metal statue from these blocks. Although its composition hasn’t changed and it possesses space-time continuity. However, its structure has completely changed, and we cannot say that the statue is the original car, as they do not have identity.
Two buildings have identical structures but remain two entities because they are located in different places in space simultaneously, lacking space-time continuity.
"Captain Jelos, conceptualize the ’Theseus’ Ship,’ distill its essence, which means: the specific relationship among all parts possessing space-time continuity! For the Theseus School, this is the ultimate form of immortality!"
No matter how long the time or how immense the force, such a concept cannot be destroyed, just as even a True God cannot destroy a mathematical theorem.
Upon hearing Aiven’s theory, Jelos, who had pondered this issue his entire life, didn’t have a sudden epiphany but felt a sense of clarity, as the school, from ancient times to the present, seemed to have seen the direction for advancement.
Before parting.
Rogers also gave Aiven a piece of advice: "If you ever have the chance to explore a land where no human has set foot, there might be unexpected gains."
