There Is No Shore in the Lighthouse

"The second his name was erased from the world, Li An understood his mother's words: live without being remembered." Delivery boy Li An took the order in the snow, accidentally entered a first-level crack, and awakened a blank illustrated book. The price was to be forgotten for life. She took the lighthouse badge handed to her by the mysterious woman Lin Deng, and unlocked the "borrowed light" to copy the power, but the price could be imposed on the person who placed the order. In order to save her mother and get rid of the fate of being passed the price, she entered the Seven Towers Trial and formed a dark page alliance with the Iron Swordsmith, the Soul Singer, the Space Dancer, and the Temporal Madman - the five exposed each other's weaknesses and wrote the curse of losing maternal love, loss of color, and loss of lifespan into a tower-destroying message.
