On the French nuclear powered aircraft carrier de Gaulle, under the cover of darkness, a multi-purpose armed helicopter quietly rose into the air, turned its nose and sped away quickly to the territory of a certain country in North Africa. In addition to the six members of the NATO armed helicopter, they also took a total of six people aboard the helicopter. But surprisingly, the four men were not regular French soldiers, but four mercenaries from a security company called “Arthur’s Shield”. These four mercenaries are very strange. They are not only of different ages, but also of different nationalities. A black man, a white man, a Mexican of Latin American origin, and a Chinese.
