Rise of the Undead Legion - Chapter 13 Main Quest!

A skilled thief gets a system in an Alternate Wizarding World. The system seems useless in the beginning since he hasn’t unlocked any features. But…

[The very first feature of the System has been unlocked.]

[Congratulations. You’ve unlocked the class feature. Due to your existing skills and experience, you have gained the Special Class "Arcane Thief" as your starting class. There’s nothing an Arcane Thief can’t steal. The more you steal, the more your Class will progress.]

[The fields of expertise include:

— Stealth Magic
— Wards
— Traps
— Enchantment
— Pickpocketing
— Knife/Short-Sword Wielding]

Wait…this is just the first feature?

[ 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?

I became the childhood friend of the protagonist in a novel. The childhood friend who died from taking drugs.
