After Ten Years of Lurking in Border Areas, I Was Invincible at the Beginning

Ten years ago, Gu Changan traveled to the Dayu Dynasty and became the eldest son of the marquis of Zhenguo. In the beginning, his father died in the battle in the south, and he was wrongfully accused of forming a party for personal gain. The military power of the marquis was revoked, and the entire Gu family was demoted to the far north - Yuman City. Princess Li Anlan of Changle, who got married on the day she was demoted, chose to divorce and cut ties with the Gu family. Ten years later, the late emperor passed away. Princess Li Anlan of Changle killed the prince, ascended the throne, and became the Empress of Yu. In the Yuman City in the far north, Gu Changan woke up and wore a yellow robe... "Your Majesty, the vassal kings from all over the country have gathered their troops to attack the imperial capital." "Your Majesty, Gu Changan has proclaimed himself emperor in Yuman City." "Your Majesty, Gu Changan's army has attacked ten cities in a row." "Your Majesty, Gu Changan personally conquered the six kingdoms in three months." "Your Majesty, Gu Changan has killed all the vassal kings everywhere." ………….. Empress: "According to my decree, I want to remarry, I want to remarry..." Gu Changan: "I have been demoted for ten years without you. Who are you wearing a yellow robe? Send an order to Yu to kill the empress."
