A boy ends up in the Immortal Realm—along with his smartphone.

No, seriously—what is this?!
He saves someone, and the guy suddenly claims to be a grim reaper… then just sends him off to a bizarre world? And all he gets is a single smartphone?

The protagonist, Bukjin, finds himself stranded in the Immortal Realm. Now, he must pretend to be the original owner of the body—Im Bukjin, a notorious troublemaker—while searching for a way back to his original world.

But how the hell do you even use this smartphone?

[Ding! Would you like to download the “Intermediate Mystic Spirit Training Technique” app?]

Wait… what? You can download martial arts?!

With nothing but his smartphone, Im Bukjin begins his journey of adapting to life in the Immortal Realm—where mastering any martial art is as easy as installing an app.
