There's Something Wrong with This Game, but Luckily so Am I

In 2032, a line appears on everyone's little finger. The transparent line reaches to the sky with no end in sight. No one knows where it leads. All I know is that when the line is broken, people will disappear. My name is Jiang Lin. I'm going to save someone. It wasn't until the day the line was disconnected that I understood what was connected to the other end of the line - A table, five people, a revolver. The death roulette will eventually shoot its own bullets. One villa, five killers. The rules say to be the last one alive, but the killers don't seem to intend to follow it. A clock with no numbers. Find your true time, or stay forever. Each of these copies is more wrong than the last. But it doesn't matter. Me too.
