Princess Taiping, dissatisfied with Li Longji’s reckless conduct, plans to overthrow his rule. The ministers have no choice but to insist that she adopt an heir from the imperial clan before they will support her plan.
Fortunately, things finally start to look up.
This is just my imagination, not official history or unofficial history. I simply want to give Princess Taiping a chance. I don’t think she would have been any worse than Li Longji, since she was raised and educated by the emperor and empress themselves.
