Lu Tong left the Grand Preceptor's Mansion and didn't head straight for West Street; instead, she turned towards Official Lane.
The medical clinic was short on one ingredient, Hibiscus mutabilis, which Miao Liangfang urgently needed for a prescription. He had asked the Medical Practice for some ground into powder, and since Lu Tong would pass by Official Lane on her way back to West Street from the Grand Preceptor's Mansion, she said she would pick it up on her way back.
By the time she reached the Medical Practice and obtained a small bag of Hibiscus mutabilis powder, paid the silver coin, Lu Tong, holding the cloth bag, walked back.
It was still early, and the streets were bustling with people. She wandered absentmindedly with the crowd, and as she walked, the people around her suddenly rushed to escape, leaving her to pause as she felt a few drops of coolness fall upon her. Looking up, she saw dense clouds overhead, and the long rain arrived abruptly.
