My Wife Saves the Kingdom Again

Modern agricultural science doctoral student Rosalie died suddenly and transmigrated into an ancient Crown Princess, but faced a hellish start. The original host's family was convicted for hoarding and inflating grain prices during a famine year, and the Emperor intended to execute the entire family. Crown Prince Arthur used his position as heir apparent to strongly protect his beloved wife Rosalie. To save herself, Rosalie relied on modern agricultural knowledge to resolve the dual crises. Second Prince Xavier, in order to seize the succession and become Crown Prince, repeatedly attempted sabotage with malicious intent. First, he sent people to burn the grain seeds and assassinate Rosalie, but after failing, he escalated to kidnapping Rosalie's parents to force her to poison Arthur. Rosalie and Arthur, as a couple, joined forces to set a trap to counter-kill Xavier, exposing his crimes. Ultimately, the Emperor permanently exiled him to the borderlands.
