Nine Princes Vie for the Throne: From the Start, I Slapped the Emperor's Uncle Hard!

Li Xian transmigrated to the Great Jing Dynasty and became the imperial grandson at just six years old. The good news: his father was the crown prince, and his mother was the daughter of the chancellor; The bad news: both his parents had been sentenced to death. The good news: the current emperor doted on him and intended to name him heir over the next generation; The bad news: the emperor was at death's door, with little time left to live. The good news: the nine imperial sons were all valiant warriors, skilled in battle and remarkable men! The bad news: every one of them had their eyes on the throne and was ready to seize it at any moment! The good news: the officials were all accomplished in both letters and arms, talented in every field! The bad news: they were transmigrators from different dimensions and different worlds! Every one of them wanted to rebel, seize the throne, and become emperor! Damn it, you think you can walk all over me, do you?! Wash your necks, then get down on your knees and sing “Conquer”! Don't wait for me to come over and beat you senseless! [Over-the-top satisfaction, multiple female leads]
