In ancient China during the Warring States Period, a nameless prefect of a small jurisdiction arrives at the Qin state's capital city to meet the king of Qin. The king has just survived an attempt on his life by three feared assassins (Long Sky, Flying Snow and Broken Sword) and has taken precautions to protect himself, including forbidding visitors to approach closer than 100 paces to his throne. Nameless claims that he had slain the three assassins, and he displays their weapons before the king, who is impressed and allows Nameless to sit progressively closer to him and tell him his story.
