Right at that moment, Ye Zi'an sensed something was amiss, because after sending out a troop, the West Mountain Camp had fewer men. The presence of the West Mountain Camp was to protect the royal city; if that force was weakened, the consequences would be unimaginable if someone ambushed and rebelled.
His concern was not unreasonable. After reporting this matter to the Emperor, the Emperor secretly sent Old Mu out.
As for where Old Mu went after leaving the Capital City, even Ye Zi'an and Yang Chuxia didn't know.
Only a letter was left behind, stating that Linhao and Yang Xiayun would marry and the banquet would be held at his private residence. As for who would officiate the wedding, Prince Zhuang would preside. Additionally, there was an apology to the Yang Family, because in such a major event, no elder would be present.
At such a time, even if Yang Chuxia was somewhat displeased, she couldn't show it, as this was something beyond control.
