He accidentally joined the transmigration craze, only to discover he'd landed in a world of idiots! It's just as modern and urban as our own, except that people here are a little less intelligent?

In math class, multiplying single-digit numbers is considered advanced material? Only university professors can do three-digit addition and subtraction?

Even more importantly, this world doesn't have the multiplication table, and people can only do arithmetic on their fingers?

And language class is just a dictionary. Do they only know how to speak? No poetry, essays, or novels?!

And damn it, I even awakened a show-off System?! I can make money just by showing off and exchange it for anything I want?!
