The General and the Leader

The Dragon Clan city lord formed factions to unify the dragon clan. His junior disciple, Long Ji, trained diligently and became a divine emperor, tasked with protecting the clan, while the city lord sought personal gain and silenced him, causing harm to the clan. Long Ji's spirit lingered after death. From him, three generations of descendants established families and became beloved, so much so that people were willing to overlook age gaps, forming uncle-niece relationships with princesses, risking their lives to treat other races kindly, and involuntarily falling in love with the eldest daughter under his command—though he was her grand-uncle, she was also the best candidate for clan leader's wife. The city lord's power was not his fault. Through cycles of reincarnation, the two finally found happiness together in the modern world. — Description from novelcodex.org
