Originally, when he heard about the incidents that had occurred to her, the Emperor had secretly speculated that perhaps this was her destined trial. At the age of ten, she experienced having her family torn apart, became displaced, and after enduring countless dangers, travelled a thousand miles to seek refuge with her relatives, only to find herself ensnared in a nightmare of a life-threatening situation, but eventually was saved by a master.
At that time, he thought the ordeal was over. As long as she didn't remember it, she would be fine, forever well under his protection.
But this time, he entirely lost his complacency, realizing that the tribulations of his Little Concubine were merely hidden and had been for nearly seven years, yet they were far from over.
If it were overt plots and covert enmities, the Emperor was confident in his ability to keep her safe. However, the hidden danger had been sown many years ago, filling his heart with worry and a sense of powerlessness.
