Pei Jiamin is an unlucky guy who was selected by the quick travel system. She thought she was getting a strategizing and dramatic script, but in the end she was frantically wiping herself off in every world. In her third mission, she traveled through time and became an overseas student who was forcibly married by a warlord during the Republic of China. Her opponent was Lu Siheng, a young marshal who was decisive in killing and iron-blooded. On the surface, Pei Jiamin smiled and nodded, "Everything is under control." Secretly, she was planning every day how to survive until the end of the mission under Lu Siheng's eyes. But she gradually discovered that this legendary murderous warlord would secretly stuff medicine packets under her pillow when she coughed, would run across half of the city because of her casual words of "wanting to eat sweet-scented osmanthus cakes," and would clumsily pretend that he was just passing by when she woke up from a nightmare. Pei Jiamin panicked - she was not afraid of Lu Siheng being cruel, she was afraid that he would become cute if he became fierce.
