Jin Yu, who was born in a declining scholarly family, took a broken volume of ancestral teachings and entered the ruined castle swallowed by time and fog. The heart of the castle seals the magic of ancient revelation, but it seduces mortals with invisible imprints and turns those who pursue the truth into stone statues. Jin Yu did not seek power or wealth, but sought to prove an unsolved prophecy in the Proverbs of Light and Shadow written by her ancestors. In the corridors where time and space intersect, he uses poetry as a curse and speculation as a shield, arguing with the sages in the illusion of the castle and confronting his own heart in the illusion. The truth of magic gradually emerges: revelation is not a gift, but a price; with every awakening, a piece of the past must be annihilated. Jin Yu must choose whether to protect her family's memory or sacrifice herself to bring light to the forgotten era. The ancient wheel of fate turns slowly. Deep in the ruins, truth and loss are only a thought away.
