Just like walking to the room's doorway, opening the door, and seeing a pair of slippers at the entrance.
Then wearing the slippers, other pieces of furniture in the house rush into view like a flow of water, one memory linking to another, threading into a connected sequence.
Fang Cheng's entry into the Memory Palace begins with this "National Dictionary" in his hand that ultimately enables the skill to level up.
As for connections, it's the most important and challenging step in building the Memory Palace.
For in the Memory Palace, all stored information must be tightly linked to one another to be sustained.
For instance, in a vast library searching for a book could involve classification by area followed by specific shelves, logically retrieving and locating the book.
Only when each piece of information is tightly interconnected can this Memory Palace remain solid, preventing it from slowly crumbling away with time.
