Synopsis：Zhou Wen suddenly awakens to find himself surrounded by courtesans; a woman dressed as a Qinglou entertainer, whom he has never met, is speaking to him. He claims he has no idea why he is here or why he is wearing the uniform of a Jinyiwei guard. While he is utterly bewildered, a massive explosion suddenly rocks the room. Zhou Wen wakes up again, this time in a vintage secondhand shop filled with antique clothing on racks and display cabinets. A grumpy, bearded man demands to know what clues he has found and tells him time is running out, urging him to hurry. Before Zhou Wen can even ask a question, he is sent back to the Spring Breeze Pavilion. Through repeated "shuttles," Zhou Wen gradually understands his mission: to uncover the truth behind the mysterious explosion that occurred over Beijing during the Tianqi era. And each time, he only has the duration of one calming incense stick to complete his task.
