Lianne was lying down in bed, too tired out from the day's activity - both physically and mentally. The way she was scrutinised by the eyes of the Sheng Family was really intense.
Of course, she knew that the sudden announcement and the departure from the norm would create huge waves. This was just the beginning for Kai wanted to reform the Shengs in so many ways.
It was only natural that the former Patriarch would have stepped down as he was getting old. Why should he continue working so hard when he should be enjoying his golden years, right?
Since he had found the one to replace him, he might as well step down.
It truly did not make sense to force one to continue working and holding on like that. Also, after a while, would it not really be that the Patriarch becomes a puppet? One cannot deny that ordinarily, someone of that advanced age would 'slow down'.
Be it because either the body becomes weak or the mind does. Worse, both.
