When Lu Xiuyuan, a Bangkok cultural relic restorer, was repairing a butterfly amulet from the Ayutthaya Dynasty, the memory of Tilapa, the ancient Buddhist amulet master, had a strange overlap. The two were forced to be involved in a supernatural chase that spanned three hundred years, and in the dual time and space of the neon city and the end of the dynasty, they uncovered the truth about the "Curse of the Butterfly Spirit". They discovered that the so-called curse was actually a war to defend the fire of civilization set by their ancestors at the cost of their lives. When modern personalities and ancient memories begin to merge, what is the ultimate choice before them: to preserve themselves, or to become a "bridge of time and space" that connects ancient and modern times and saves the 877 unique volumes of civilization? Every step of decryption is accompanied by the loss of memory and the weight of history.
