Time travel + paralysis + prince + seizure of power + party struggle + crushing + war. The protagonist travels through time and becomes a prince. He faces the emperor's father, the queen's mother, his capable younger brother, the paralyzed man, and the enemy country that he has never been very worried about. It depends on how he thrives in the hot land of Nanli. It depends on how he uses all his methods, rationally uses what he has learned throughout his life, and plays with the dynasty.
Well written😌[laughing]
