Blind-Box Survival: Randomly Transmigrate and Fight for Your Life for Seven Days

[Infinite worlds + horror games + blind boxes + instances + terror + the supernatural] I was forcibly dragged into a deadly game spanning time and space. Each round begins with a random blind box. No one knows where they'll end up next. It could be the chaotic Five Dynasties and Ten Kingdoms period, where rebel soldiers surround and slaughter you; It could be a bloody game where luck matters more than strategy in Monopoly; It could be a zombie wasteland, where you struggle to survive the tide of the undead; It could be a haunted house, where vengeful ghosts come to claim your life; It could be a World War I battlefield, where you fight to survive a hail of bullets; Or it could be a modern city, where the gangs hunt you down relentlessly. There is only one rule: Survive for seven days and complete your mission to make it back alive. Survive, and you get to open a blind box: Cash, pistols, enhanced physical abilities, supernatural powers, haunted artifacts... The harder the challenge, the more terrifying the rewards. I have no cheat, and no one to rely on. I can only fight to stay alive in one desperate instance after another. Others want to lie flat. All I want is to survive seven days, then face the next deadly predicament.
