After the political revolution in Tang Long, the relationship between Li Longji and Princess Taiping changed from an ally to an enemy, but many people paid attention to them while ignoring a key figure, that is, Princess Taiping's brother and Li Longji's good father Li Dan.
Li Dan has always controlled the forces of both sides like a wooden bridge. On the one hand, if Li Longji is the dominant party, then he is likely to become the emperor's father like Tang Gaozu. On the other hand, if he indulges Princess Taiping, then Wu Zetian's case is also vivid.
