Di Fuyi was enlightened by the useful pieces of advice given to him. When he was satisfied, he asked Mu Feng to pay them some money and let them go.
In order to prevent them from spreading the news about Gu Xijiu's pregnancy, Di Fuyi cleared their memory of the events of the day, so they no longer remembered that they had seen the Lord. He managed to get what he needed to know, so there was no more time to lose. He quickly returned to the room as he was worried that Gu Xijiu might become distraught with anxiety once she saw that he was not there.
The whole process took him only an hour. When he got back into his room, he was relieved to see that Gu Xijiu was still sleeping soundly on the bed. He walked out of the room and was surprised to see Mu Feng by the door, standing straight like a wooden pole. Di Fuyi was slightly baffled. In fact, he never requested any of them to guard the doors in the Biwu Palace.
