[ THE EARTH YOU KNOW WILL END IN SIX DAYS ]After the text appeared the world was no longer the same. The apocalyptic scenarios that humanity could imagine began to occur one after another.Monsters, meteors, natural disasters. All of them came after the six-day countdown ended.Fortunately, humans are given something to fight back. Or actually to make things much more interesting. They became Players.No one knows who is behind all this.Humans have no other choice but to survive amid this chaos by playing.But Clyde didn't live it like the others. Because he was the only human who had the lowest difficulty in the End Time Game.He plays in Easy Mode, and he already read this kind of thing in web novels. Except, there are no such thing as 'Regressor' in those webnovels. Until he met them.“Wait, I only hit that monster once and it died right away?!”“Whoa, I got an A-grade weapon right away!?”“There are... 4 Regressors?”How is Clyde's journey in this apocalyptic world with the lowest difficulty?

What if you were transported to a fantasy world with no special abilities, no OP weapons and no status screen to boost your stats? Never mind finding the dragon’s treasure or defeating the Demon Lord, you only need to worry about one thing—how to stay alive.A group of young Brits wake up in a strange, fantastical land with creatures from myth and legend. They are given archaic weapons they don't know how to use and told to do their best.Convinced it has to be some kind of virtual reality RPG, all the people summoned form parties and set off on their adventures, leaving behind the people nobody wants in their group.Story of my life, thinks Colin.

“Can’t I properly read stallion novels anymore!”
