"After countless experiments, the ancient wizards discovered that using three Will Runes to build the initial foundation of Mental Power was the most perfect and stable structure.
Three was a marvelous number—it was the simplest stable planar structure and the starting point for constructing complex three-dimensional models."
Ian let the model of light points hover in midair and continued explaining:
"When an ordinary person successfully condenses their first Will Rune in their Mental Sea through a meditation method, it marks their formal entry onto the path of wizardry.
But that is not enough, because a single rune is isolated and unstable, like a lone tree unable to hold up a forest.
They must condense a second and a third, allowing the three runes to resonate with and support one another, forming a self-consistent cyclical system."
The triangular model's glow became bright and stable.
"Only then does the lake of Mental Power gain true 'banks' and 'channels,' allowing it to circulate and grow.
That is why condensing three Will Runes is the official mark of entering the Low-level Wizard Apprentice realm."
Dora raised her little hand. "Mr. Ian, then why three? Wouldn't four work? Or five?"
"An excellent question." Ian nodded approvingly.
"The ancient wizards tried every possible number. They found that with fewer than three, the structure was unstable and prone to collapse; with more than three, the Mental Power's 'carrying capacity' was insufficient in the initial stage, and forcibly condensing them would warp the rune structure and leave the foundation weak. Three was the optimal balance between efficiency and stability."
He paused to let Dora absorb the concept, then continued:
"As cultivation improves and the lake of Mental Power continually expands, it requires more complex and powerful structures to contain and circulate it.
Therefore, with every advancement in realm—from
