After I Transmigrate into a Book as a Cannon-Fodder Side Character, I Save Myself by Listening to the Rain

Police detective Su Nianqing enters a world where two books have merged and becomes a doomed supporting female character destined for a tragic death. She rejects the compulsory System that orders her to reform the heroine and relies on mind-reading to save herself, one step at a time. She digs into the secrets behind the Marquis's household swapping babies, builds the Listening Rain intelligence network, navigates court intrigue, and makes devoted friends and mentors. She tears up the script fate wrote for her and takes control of military power and commercial trade routes. Amid the storms of a chaotic age, she rises to the top with a clear head, and love deepens between two hearts.
