Zhu Yu, the former emperor's daughter, is now Miss A Yu, the famous teahouse owner in Yanhuo Alley. In the past, she was a beautiful woman, but now she is making tea with her bare hands. Anyone who sees her will praise her for her extraordinary grace, but it is a pity that she is a helpless orphan. There are three things in Miss Ayu's teahouse: a lot of old books, a lot of stories, and a lot of customers in military uniforms. The leader was none other than Lu Chengxiao, the new warlord who was stationed here with his iron-blooded military exploits. Everyone said that Commander Lu was cold-faced and decisive in killing Yama, but he loved to go to this small teahouse and always liked to tease the cold landlady. Lu Chengxiao: "Miss Ayu, your tea seems to be bitter than other teas." Zhu Yu lowered his eyes and smiled, brushing the hot teacup with his slender jade fingers: "Maybe the tea maker feels bitter." What he thought in his heart was: Nonsense, seeing your face, I can't wait to add three kilograms of coptis into it. He didn't know that her slender wrist had once been tied with a palace bell that symbolized the prince of a country; he didn't know that the old book on which she splashed the ink with tea was a lost military defense map from the previous dynasty; he didn't know that the coachman who knelt in front of her on a rainy night and followed her to the death was once a royal general in charge of thousands of armies. She lurked in the market, scheming in the fragrance of tea, and worked every step of the way, just to overthrow the new regime behind him. But she didn't expect that this eagle dog of the new dynasty would protect her time and again in the troubled times. Even when her identity was revealed and the city was full of enemies, he used his body to block the spears and short cannons for her, and asked her in a dumb voice: "A'yu, if I give this world back to you, would you like to... Make me a cup of tea that is not bitter?" - She is an old dream he buried with his own hands.
