Gu Xingyao, a 29-year-old doctor of meteorology, was struck by lightning during a field trip and traveled through time to become the daughter of a minor official in the imperial prison of the ancient Yan Dynasty.
In this era, people depended on the weather for their livelihood, but Qin Tianjian relied entirely on ancestral formulas and astrological divination to predict the weather. The accuracy all depended on luck. In years of disaster, he was often reviled by the people. Gu Xingyao originally wanted to pretend to be stupid and get by, but when she saw that there was no rain in the summer, the crops were dying, and refugees were everywhere, she couldn't sit still anymore.
Based on phenomena such as changes in cirrocumulus clouds, changes in wind direction, humidity and heat, and ants moving, she comprehensively judged that there would be drenching rain within three days. Her casual remarks were overheard by the Qintian Supervisor, and she became the first female official in two hundred years.
Xie Lanting, the young eunuch of the Qintian Prison, was from a noble family and was strict and rigid. He initially believed that Gu Xingyao's words such as "relative humidity" and "barometric pressure gradient" were lies to deceive the public. But her predictions came true time and time again, making Xie Lanting begin to doubt what he had learned over the years.
The collision of science and experience is inevitable, and with frequent natural disasters, the two must move forward hand in hand - behind every accurate forecast are hundreds of lives.
