It would be unreasonable for the palace to be left empty. Moreover, the palace was built on the ground with the best Feng Shui out of the entire capital city, where every inch of the land was valuable.
The emperor thus seized the opportunity to ask Gu Xijiu of her opinion about the place. Gu Xijiu insisted on keeping the palace, so she shook her head to dismiss the emperor's suggestion. "Do not touch anything about the palace. I am keeping it for my personal use."
The emperor decided not to ask anything more. Before Gu Xijiu departed, she decided to erase Rong Jialuo's memory about his previous life. His past life had not always been good. He had been living with heavy burdens all his life. In the end, his body was taken by Mo Zhao, and he died a tragic death.
