I have just the right book for a clever adventurer like yourself.
It's called Pyresh's Formula.
Long ago, a genius mathematician traversed the whole world,
leaving behind great math formulas he discovered in places he visited.
And his findings have been compiled into this book.
Follow the travels of Pyresh,
and you can experience his anguish as you read along.
Well? Do you want to give it a read?
At the low low price of one billion silver.
It's quite the bargain!
What? Too expensive, you say? Really...
You can't put a price tag on knowledge...

Hmm...? Is that hesitation I see in your eyes?
Perhaps, you aren't so well-acquainted with numbers...

Remember... There's no refund policy,
so please finish the book even if it hurts your brain.
