Lan Zihao must be quite extreme. When he was about to start the assessment regarding the dispute within the Fang Group, he said that he would bring along a concubine as well as a servant to the palace, and he was referring to Xia Qiao and Yi Xue back then.
However, the announcement was too sudden, and that was why the people in Chang City weren't sure whether the Prince was serious or not, and that was why they had only spread rumors about how the Prince would take a concubine and palace maid, but they didn't dare specifically spread rumors that the person who would be his concubine would be either Xia Qiao or Yi Xue.
That was why even the Emperor knew nothing about it when he suddenly arrived in Chang City to request a further explanation from his youngest son. In the Imperial Palace, the Emperor had only heard that his son would take someone to be his concubine, but there were no rumors about the person his son would bring to the palace.
