Yu Qiuyu is a top contemporary meteorological observer. He is stationed at a high mountain observation station all year round and takes it as his mission to accurately predict weather and protect the safety of a place. She was used to looking for patterns between data and clouds, but she never thought that a rare superposition of magnetic storms and thunderstorms would involve her and the observation equipment in the turbulence of time and space. When he opened his eyes again, the familiar radar and satellite cloud images disappeared. In front of him was the chaotic era of the Three Kingdoms, where flags were flying and wars were rising.
Armed with modern meteorological knowledge, she has become the most special existence in troubled times. She can predict heavy rains through cloud phenomena and help marching troops avoid flash floods; she can use monsoon patterns to plan safe routes for grain and grass transportation; she can even resolve disease crises in military camps based on changes in astrology. This "power to the sky" made her unexpectedly enter the vision of Shen Yan, a young general under Cao Cao.
Shen Yan is both wise and courageous, but he is constantly under suspicion due to secret fights in the court, and he hides an unknown loneliness in his heart. When they first met, he regarded Yu Qiuyu as a "monster woman", but after witnessing her resolving crisis situations with her "cloud-watching technique" time and time again, he gradually grew to admire and be curious about her. In troubled times, Yu Qiuyu not only needs to use professional skills to protect herself, but also adapts to the feudal ethics of orderly hierarchy. Shen Yan's protection and trust have become her only warmth in the troubled times.
When modern science meets the ancient art of war, and when independent women meet heroes in troubled times, they redeem each other in the light of swords and shadows, and their love gradually grows amidst the ups and downs. Can Yu Qiuyu rely on meteorological knowledge to gain a foothold in the Three Kingdoms? Can her love with Shen Yan transcend the barriers of time, space, identity and troubled times?
