Sign-In in a Chaotic Age: Steampunk Great Ming

In the blood-soaked arena of the Qing Dynasty, I, Wang Lie, a Ming slave awaiting execution, awakened the [Iron-Blooded Overlord sign-in System] at the very last moment of my life! My first sign-in was at the arena, and the reward was [Three Hundred Spartan Warriors (Remnant Souls Edition)]! In an instant, the thirty slaves around me who were also condemned prisoners had a startling change in their eyes. Their muscles bulged, and they transformed into gods of war! We smashed shields with wooden clubs, built a wall with our flesh and blood, and slaughtered our way through the arena, leaving the former Ming princess disguised as a merchant's daughter in the stands utterly stunned. Escape alive? No, this is only the beginning of my quest to overturn this steam-powered age!
