Shen Qingtang, the noble daughter of a prince in the capital, is proficient in music, chess, calligraphy and painting. Her only worry is that she is doomed to die trapped within those four red walls in her life. In order to escape from the imperial edict granting marriage, she packed up her belongings overnight, took her pitiful fantasy of the world, climbed over the wall and ran away. The good news: She made it out and breathed freedom. Bad news: She is a "good-for-nothing" young lady who can't even read the road, was defrauded of all her money, and can't even wash dishes. Just when she was so hungry that she was dizzy and almost sold by the trafficker, the cold-faced knight in tatters and carrying a rusty iron sword passed by and took her out of the hands of the trafficker. Shen Qingtang: "My hero, I have a hundred taels of gold here, and I hire you to protect me!" The knight glanced at her and sneered: "Deal. But let's talk about it first. I don't care for idlers. I'll go back if I cry halfway." Thus, the journey of the Hou family's daughter officially began: In order to save money, she relied on the actuarial skills she learned from the Hou family to revitalize the knight's poor escort agency; In order to defend herself, she used embroidery needles to practice concealed weapon techniques. Although her accuracy was average, she was better at concealment; in order to survive, she changed from a delicate girl who could only eat bird's nests to a chef who could cook in a big pot. Later, when the troops of the Hou Mansion chased her to the border and tried to take her back, Shen Qingtang was sitting on the second floor of the restaurant, holding an abacus in his hand, and standing beside him was the cold-faced knight who had been trained by her to be a "loyal dog". Shen Qingtang smiled slightly: "I'm sorry, I am now the owner of the largest escort agency in the world. This girl will not get married."
