Zero Moment Annihilation

(No System, no harem, no wish-fulfillment, no invincible protagonist, and no brainless plot. If that bothers you, don't click.)

In this strange world, the clock strikes midnight and you return to reality.

As long as you keep taking part in games and collect the items called Rings, you can make a wish come true.

I thought it was all just a so-called “Game of the Gods” created by a bored deity, but it turned out that everything was heading toward destruction.
