In 2046, the time machine was invented in Huaxia. Along with it came the first time-travel security force in human history, the Envoy Corps. But excavations soon uncovered cultural relics and historical clues indicating that people carrying modern weapons had transmigrated to the era of Emperor Wu of Han long before 2046. To investigate the cause and track down the first suspected time-travel terrorist, members of the Envoy Corps also transmigrated to the era of Emperor Wu of Han. After a series of counterterrorism operations across time, they won the emperor's trust and were granted the title of Envoys of Great Han, along with the ceremonial staff of authority.
An envoy is a bearer of the staff of authority.
• Bearing the staff of authority grants the power to execute anyone without official rank.
• Bearing the staff and battle-axe grants the power to execute officials ranked below two thousand bushels.
• Bearing the staff and battle-axe by imperial delegation grants the power to execute generals campaigning in the emperor's name.
