After the System Abandoned Her, the Heroine Returned to the Killing Fields

(Mature older woman vs. sweet young man, the second male lead rises to the top, a groveling ex-husband arc, face-slapping, feel-good fiction, with romance) Twenty years after successfully completing her mission, Jiang Wuyou discovered that the System had been secretly raising another Host. It had given this new Host all the resources, and even the face Jiang Wuyou had when she was young. The first time her husband, Gu Chen'an, saw the young model, he was smitten and began appearing with her in public at all kinds of events. Jiang Wuyou asked him, “Do you love her?” “Are you done making a fuss? Why are you picking a fight with someone young enough to be your daughter?” he retorted. Jiang Wuyou heard the System gossiping with the others: “I really regret signing a contract to stay bound for life. It'd be better if Jiang Wuyou just died.” Jiang Wuyou confronted it. The System said, “Sorry, babe. Water flows downhill, and Systems climb higher. Can you give me what Xu Tangyi can?” Divorce. Break the bond. She would return to the battlefield. What, the new Host had a System to help her cheat? Then Jiang Wuyou would let her taste the bloodline suppression of the original heroine. What, the new Host had a man to fall back on? Jiang Wuyou would show her how far she could get without a man. The System urged her to come back. Jiang Wuyou pointed at the Systems lined up in front of her, waiting to be bound: “Didn't you say water flows downhill, and Systems climb higher? With so many Systems here, I can at least pick one.” Her ex-husband begged her to get back together. She tossed her hair. “My kids are grown up. What do I need you for?” A powerful villain pursued her. Jiang Wuyou said, “Come on, let me see how strong you are.” Later, she discovered that the truth about this world was a little different from what she had imagined.
