Rebirth of the Eldest Princess

Before her rebirth, she was the eldest princess of the Rose Kingdom, one of the five vassal kingdoms. She grew up in the favor of her father. She was born with a noble status and married the prince of Hengyu, becoming the most respected queen of the Hengyu Kingdom. War broke out, and the Rose Kingdom was defeated and attached to Hengyu. Only then did she realize that the favor he gave her was just a monarch's means. She fell from the palace and pavilion and returned to her cardamom years. She paid back everything she owed me, little by little. Watch how the reborn eldest princess gets rid of the scumbag, trains the general, and protects the Rose Kingdom. One day I have the power to kill all the dogs in the world who have failed me.
