Old master is getting suspicious

As she finished speaking, she turned to look at celestial master Gu and smiled politely before saying, " I am not questioning your abilities, master Gu. I just think that my father is being too antsy by bringing you here, calling you when the case is simple as an accident, I think it's similar to wasting your time and nothing else, I hope that you will not mind." 

The Gu family was still one of the powerful families, even though they were not as powerful as the Fu family, they were more prominent than the Ji family, she did not want to offend the Gu family either which was why her words were rather cordial.
