Sylvia Legend

Silvia, the subjugated princess, became a gladiatorial slave in the Colosseum of the Seleucid Empire. When she was forced to join an imperial expedition to the snowy mountains, she discovered that the world was far stranger than she imagined - a mysterious being who called himself the "Monitor" was hidden in the snowy mountains in the north, and a small country in the south actually possessed guns that transcended the times. A secret message guides her to escape to the land of resistance, but plunges her into a deeper puzzle: the overseas powers that provide weapons behave unpredictably, and the prince of the empire is caught in internal strife. And at the junction of glacier and neon, an ultimate secret that can subvert cognition is waiting to be revealed... She vowed to break out of the cage, even if what imprisoned her was the lie of the entire world itself.
