Life-Threatening System

One day, when I was about to die, a scum system that claimed to be a happy life welfare system came into my mind. The system said it would give me a happy life, but... After experiencing each world, I suddenly realized that this is not a happy welfare system! The system only hangs on you for a moment in every world. You can't survive until you die, and you get critically ill at every turn. This artificial staff is clearly a life-threatening system!
