This was not strange in itself; after all, he had lost such a valuable item. If it were anyone else, they might have even harbored thoughts of murder. But Ye Wudao, through observation, discovered that this blond European man, though appearing to be very angry, was definitely putting on an act.
Don't forget that Ye Wudao was not only a master but also an actor. Although he had only made one movie, he had learned a good deal about acting during the filming. So it was easy for him to see that this blond man was pretending.
It wasn't just him putting on an act; the person in charge at Tianlong Security Company was also playing along. It was clear that this whole affair was orchestrated by them.
