I thought it was just an ordinary time travel through "Infinite Horror", but you told me that "Infinite Horror" is just an internal beta version, and the next step is the main meal.
Game version:
Goal: Victory, guess the details.
Process: Leave enough resources for the entire team, whether material, spiritual, real or illusory, until victory is found.
Rules: 3 team members enter the specified world at regular intervals, in random order. If the former dies before the time is up, the latter will enter immediately. If the time exceeds the time, the former is allowed to survive at the same time. If all of them die, they will enter the next world. On the premise of not breaking the rules of the world, you can use abilities recognized by the world where you live, and support ability and item exchange (as long as you can afford the price).
Literary version:
"What is this? The Demon King's conspiracy?! Or is it the God King's game?! We are just ordinary people, so what does victory have to do with me!"
Frank version:
This is a story about three girls running around in several worlds looking for something. They are pushed to different worlds by fate step by step and grow up in a difficult situation. Finally, they plan to give up but accidentally hit the farm. . .
