Xiuying and his members moved to the police training ground a few days before the of their attack on the sub units of the syndicate.
Xu Bing was very overwhelmed by the large number of men under the young man.
If his admiration for the boy before wasn't that obvious to his men, then now we can say that both all his men and Xiuying's members also realised it.
They way he made the boy to handle the operation and just agreed to almost everything was quite surprising to his men.
Even though the King had said that the chief supt. and his men were to follow whatever instructions that Xiuying gave, they had expected their pompous boss who felt very annoyed then to be giving the young man a hard time.
But instead, since their boss realised that the young man was that "capable" man who saved his son, he has really mellowed for the boy.
