Li Xian, a modern soul from an ancient official family, originally wanted to rely on her martial arts skills to stay put and stay away from the intrigues of the family. Unexpectedly, the emperor granted her a marriage and actually wanted to marry her to the second prince whose IQ was stuck in childhood!
In order to escape from marriage, Li Xian teamed up with the good princess Liu Li, who was also a time traveler, and deceived the gentle young man Liu Yanqing into planning a "bandit robbery" drama, and ran away to the frontier fortress to learn skills from his teacher. I thought I could stay away from the troubles in the capital, but by mistake, I was involved in the battlefield. A woman disguised herself as a man and transformed into a soldier. She killed enemies in the desert and made military exploits. She also accidentally discovered the secret of time travel - the gathering of three stars can return to the modern age!
From escaping from marriage to going to the battlefield, from investigating cases to escorting people, Li Xian thought he was just a passerby in this world, but in his desperate efforts, he became the most reliable person for others.
