I, the Regent Prince

Setup: [Two male leads + scheming second male lead + steady male lead + comedy early on + dark turn later + historical romance + transmigration] The Ninth Prince, Li Yunxuan, cares nothing for power struggles and loves dressing up. He enjoys putting on makeup and dressing as a girl. A year ago, he rescued Nie Wenyan, a young marquis from an enemy kingdom. Time passed swiftly, and the two kingdoms of Zhao and An stood on the brink of war, with a major battle about to erupt. At this critical moment, the State of Zhao needed a princess to travel to An and negotiate peace. Upon hearing the news, Li Yunxuan volunteered without hesitation. The journey was fraught with danger: he had to navigate complicated peace talks and was unexpectedly possessed by a fox spirit. Nie Wenyan, too, had a secret: he was possessed by a wolf spirit. Together, they embarked on a trial to cultivate immortality. As cultivation and peace negotiations intertwined, they met all sorts of people and encountered all kinds of events. Li Yunxuan relied on his calm composure to overcome numerous challenges, while Nie Wenyan faced them with cool-headed cunning. As they grew closer, their hearts slowly drew together. In the end, they became a sweet and enviable couple, weathering life's storms hand in hand.
