Bai Qianxue is a history professor in modern society. She was single. In her thirties, when she was dull and unremarkable day after day, one day, she was walking on the poplar path of the school and suddenly fell into a bottomless sinkhole. When she woke up, she unexpectedly discovered that she had traveled back in time 2000 years ago and became the princess of Suzulan, a large seaside country that did not exist in history. She was twenty-eight years old and had both civil and military skills. She had been determined to go into battle to kill enemies and protect her country since she was a child. At that time, the neighboring country of Changfeng also had a young and promising figure. Yang Shuo was the most powerful general in the country. He had great military exploits and was admired by the people. They met in a melee between the Three Kingdoms caused by the Mosuo Kingdom. The two were incompatible at first, but later due to some reasons, they gradually changed. What kind of sparks will arise between the modern-thinking princess and the feudal and conservative general?
