"I learned to find clues for the future from history, Grandma."
The girl's voice remains gentle, but the wisdom contained within it is now beyond comparison:
"Time is not as we once thought, a straight line flowing from past to future.
It's more like a massive spiral, where past, present, and future exist on the same circle, just at different heights."
She reaches out her slender fingers, sketching some complex trajectory in the air:
"When we master the correct observational methods, we can explore upwards or downwards along this spiral, to see images of other time nodes."
Astraea nods, her eyes full of pride.
She realizes that the sapling she has carefully cultivated has now grown into a towering tree.
"It seems this journey has led you to find your own path."
The old woman's tone carries a sense of relieved comfort:
"I only taught you the basics of astrology, but what you have mastered now is truly the Time Secret Technique."
