Good news: As the most talented woman in the capital, Shen Qingyi finally escaped from the rumored marriage to a sick man who was married on the tip of his finger and was said to be extremely weak. Bad news: Her money was stolen while running away from her marriage. In order to earn a living, she had to change into men's clothes and apply for a bodyguard job with her half-baked family swordsmanship. Even worse news: Her employer is the would-be fiancé whom she escaped from - the third son of the Xie family, Xie Rongyu. Shen Qingyi: ... Is it still too late to run away now? Xie Rongyu: This knight, I'm surprised to see your bones. Although your swordsmanship is messy, the advantage is that you look... Familiar. As a result, Miss Shen, who used to be full of knowledge and could only do embroidery, was forced to start a hard-core knight's career of "holding a sword to protect the master during the day and reading military books at night." Xie Rong and this man, in front of others, are weak and noble young masters, but behind others, they are scheming foxes. He coughed and instructed Shen Qingyi: "Ah Qing, that bandit is too fierce, I'm afraid." Shen Qingyi gritted her teeth and stood in front of him, while muttering in her heart: I'm afraid of your size! Do you think I'm blind with the hidden weapon that flew out of your sleeve just now? Not long after, there was a rumor in the world: Young Master Xie, who knew no tricks, was accompanied by a beautiful young swordsman with average martial arts skills but a huge temper. Until one day, Shen Qingyi's identity changed. Xie Rongyu leaned her against the mahogany table in the study and smiled as warmly as jade: "Miss Shen, we've played enough of the game of 'Sword to the End of the World'. Isn't it time to talk about our unfinished marriage?" Shen Qingyi: I treat you as a brother, but you actually want to be my husband? !
