After Emptying the House and Fleeing, the General Clings to Me Night After Night

[Transmigrate into a book + faux siblings + revenge through ingenious mechanisms] She transmigrated into the body of a cannon-fodder villainess who had been poisoned to death. To avenge an old grudge, Jiang Fuyun unlocks ingenious mechanisms and devises brilliant plans. Amid one perilous battle of wits after another, she joins forces with her stepbrother to take revenge. She empties the Marquis’s residence, then heads straight for the frontier to find her “dead” brother. But her supposed dead brother died after taking the male lead down with him, leaving behind a note telling her to seek out the cold-blooded General Who Guards the North. After a long silence, the unresponsive System suddenly sprang back to life? System Warning: [The general’s bond value has exceeded the limit! System calculations overflowing! Initiating emergency,] The general sternly drills his troops by day, but late at night he climbs through her window and begs her to repair his crossbow: “My lady, please help me…” Even more frightening, this man is full of traces of her “late brother”! When enemy forces finally close in, she commands countless wooden kites to blot out the sky. At the victory banquet, the drunken general pulls her tight against him, and one whispered sentence leaves her frozen. “Fuyun, little sister…your brother lied to you…” Gripping his lapel, she asks in a trembling voice, “Who are you, really?!” He kisses away her tears and smiles. “I changed my identity so I could marry you openly and honorably.”
