Appreciation

Despite the rejection, Master Gu Er became immediately impressed by this beautiful young lady. After some serious conversation, Master Gu Er realized Lu Yan's background was very similar to his adopted daughter. So he called Ye Qian over.

Ye Qian had done everything to guard against Lu Yan, but she couldn't do anything to stop Master Gu Er from appearing before Lu Yan.

The thing that Ye Qian worried about the most happened. Master Gu Er quickly discovered the similarities between Lu Yan and Mrs. Ye.

When a person reaches a certain age, nostalgia becomes a feature in their lives. The disappearance of his biological daughter was regret in Master Gu Er's heart, and that regret only grew with time. 

Ye Qian was ultimately just an adopted daughter. The more Ye Qian proved herself, the more Master Gu Er was reminded of his biological daughter. Was she still alive? If she was, would she be as capable as Ye Qian? Or even better?
