I Get Daily Card Draws, Yet I Was Captured by a Monster from the Start

The protagonist has transmigrated, and the world is broken. The game is a patchwork, and the System is a little messed up. Immortals battle monsters, with guns, cannons, magic, martial arts, and flying swords. I’ve never played a game like this either. I’ll do my best to sketch a few characters, and you can do your best to read along!
