The Sparrow's Feather Lock

Synopsis: Xu Fusi wanted to save his beloved fiancée, who had fallen for someone else. To do so, he approached the Yan dynasty's spoiled and willful young princess. Once he had achieved his goal, he simply turned on his heel and left. With the System's help, he changed his appearance, took up a job as a teacher, and cultivated a whole group of scholars preparing for the imperial examinations. Years later, Xu Fusi had made a name for himself and was preparing to marry his sweet and gentle fiancée from his previous life. But the young princess, whom he had once doted on and then cruelly abandoned, stood before him with a sword in hand. "Come with me." The princess rested her sword against his neck and gazed at him calmly with phoenix eyes. "Kill the woman you're about to marry, then come with me." "Dengdeng, which one will you choose?" The young princess's former Grand Tutor, Su Deng, and the retired academy teacher, Xu Fusi: "..." The System had already completed its emperor-raising plan and successfully escaped its scumbag Host, returning home to enjoy retirement. Then one day, it suddenly found itself missing the years of camaraderie it had shared with its scumbag Host and decided to go back and see how he was doing. The moment it transmitted its data and opened its eyes, its CPU nearly exploded. "Damn it! Scumbag! What happened to you?!" The scumbag: "..." "Thanks to you, I'm dead."
