When he walked through the narrow, long pathway, hearing the explosions and screams rising like tides, and entered the observation room next to the real-life test field, "Shadowless" Duan Rui's heart was palpitating again and again.

Duan Rui was among the best assassins in the ten or so Sectors at the edge of the third quadrant of the Imperium of True Human Beings.

His amazing abilities of assassination and survival could be seen from the fact that he had retreated from more than three hundred assassination operations safely and lived more than a hundred and forty years in one piece.
