Everything that she did was done in secret. Aside from Sima Zhi Yuan and a few others who knew about it, the other clansmen were kept in the dark.
During these three days, even more people arrived in their town. Just like it happened during Ximen Feng's wedding, a few had received invitations while others had come on their own accord. They came in order to draw closer to Sima You Yue.
As for the Green Spirit Sect, they had remained quiet these few days. They didn't try to assassinate anyone else. However, this caused the Sima Clan to be even more on guard.
On the day of the great celebration, Sima You Yue went out to the front of the courtyard in the morning. There were many guests today, so she had to help entertain them.
Because she was rather young and was not very senior in position, the people that she received were of the younger ranks. However, Sima Zhi Yuan ended up bringing her by his side to receive those who were more senior.
