Lu Xiao didn't return to the Prince Mansion immediately this time, but went back to the banquet hall, sat down, and drank some wine until the palace feast ended before leaving.
He didn't know that, shortly after his departure, a spy from within the palace appeared before the Emperor.
And reported the private meeting between Lu Xiao and Princess Consort Chun.
The spy was too far away to hear their conversation clearly, but he could read lips and roughly translated the content of their dialogue.
As for their first meeting, since it hadn't drawn the Emperor's attention, no spy had been sent to follow, so that remained unknown.
After listening, the Emperor fondled the ring on his finger.
He commanded, "Go investigate, during the time when the Fourth Prince was injured at Guardian Temple, if there was anything else that happened."
"Yes!" The spy quickly withdrew.
Not long after, an external spy requested an audience.
The Emperor had the person summoned.
