The consort of Prince Rui did not know what had happened in the East Palace, and why the Empress had summoned her.
Moreover, she was summoned to the East Palace, not the Empress's Kunning Palace.
As it happened, Prince Rui was not at home, and the consort of Prince Rui had no one to make decisions on her behalf, so she had no choice but to ride in the carriage sent by Eunuch Su.
When the consort of Prince Rui arrived at the East Palace, Empress Xiao, following the leads of Ning Wang and Wo Linlang, had finally traced the cause of Wo Yang's death.
The matter of Wo Yang's death had been dealt with cleanly, to the point that even Empress Xiao could not find any flaws.
But sometimes, the absence of flaws is the biggest flaw of all.
Since the consort of Prince Rui was a prince's consort, Empress Xiao would not use torture on her, let alone the fact that she was pregnant; Empress Xiao simply got straight to the point and questioned her about the Crown Princess and Ning Wang.
