turned into a death game and the players were all trapped inside, he took it upon himself to
defeat the final boss and set everyone free. However, as he lingered in the game afterwards while
everyone else logged out, he suddenly found himself falling unconscious. He then wakes up in an
unfamiliar field, and comes to discover that not only is he still trapped within the game’s world,
but that 500 years have passed since he defeated the final boss. He needs to find his way through
a world that is now unfamiliar, and figure out what happened to the world 500 years ago after the
boss was defeated, and all the players logged out.
