Situ Ce arrived at the Prince's Mansion and exchanged a few words with Lu Chen before leaving directly, without lingering too long at the North Prince Mansion.
Lu Chen suspected that Situ Ce's visit to North City was not as simple as just conveying a message; he had seen in Situ Ce's file that another purpose of his trip was to test him.
With just a few questions asked, how could he probe his secrets?
Lu Chen suspected that Situ Ce might have been in North City for some time without his knowledge, so he immediately summoned Bai Qingqing to the courtyard.
Bai Qingqing, the Deputy Commander of the Shadow Guard, certainly would have received intelligence from other Shadow Guards upon her return to Yan County; asking her would likely reveal how long Situ Ce had been in North City.
After a short while, Bai Qingqing arrived in the courtyard, and upon entering, she performed a courtesy and said, "This servant pays respect to the Prince."
