Modern girl Lin Wanshu accidentally traveled through time and became the daughter of a small official in Chang'an during the prosperous Kaiyuan era. She was full of joy and wanted to experience the romance of the Tang Dynasty, but gradually discovered that there were some silent "rules" hidden under this splendid and prosperous age.
She discovered that at night in Chang'an City, there would sometimes be the sound of uniform footsteps, like an army marching at night, but there was no one around. She discovered that the lifelike dough-making figures at the market would have syrup dripping from the corners of their eyes. She even discovered that the moon reflected in the water in the ancient well used for praying in her house was always blood red.
This prosperous age itself is a huge, living "shadow puppet stage". All the people living there, including emperors, generals, traffickers and pawns, are like "shadow puppets" pulled by invisible threads, following the established "historical script" to maintain the perfect appearance of a prosperous age. Any attempt to "change history" or "in-depth intervention" will disturb the "rules" that maintain the stage, causing the "shadow puppets" to go wrong and show all kinds of weirdness, just like the self-repair and rejection reactions of the stage program.
As an "outsider", Lin Wanshu is a "living person" who should not exist and has no threads to guide him. She can see these strange things and will be noticed by those "gone shadow puppets". Her presence itself is constantly disturbing this exquisite stage. The deeper the customs she experiences and the more prosperity she comes into contact with, the more intensive and targeted the strange events surrounding her become. She is not fighting against monsters, but playing a silent game of terror with the order and will of the entire "prosperous age" itself.
Very pretty.
