In Guo's and Ben’s eyes, it seems that there is only money interest. Yan, under the banner of being an employee of the Research Office of the University of Hong Kong, makes them willing to provide food, drink and sleep for Yan. The two ambitious people didn't expect to recruit a person who was exposed as a little assistant. They went to an expert to identify and study. They didn't expect that the expert was intentional and denied all Yan's nonsense!
