The Book of Invisible Ink

Welcome to 赫丽奥斯塔图书馆. If you want to read any of the books here, please let me know. Yes? Do you want to know about that book? Hmm...the paper seems strange. There's depression marks as if someone wrote, yet no words are here... Oh! This book is written in invisible ink. I know about this ink, it's way to keep information or techniques hidden. But this is the first time I've actually seen it used. Wow!

It's hard to make invisible ink, so it's hardly used. It is used only when top secret information shouldn't be revealed. I still can't believe I'm looking at it, this must be important!

Do you want to try and read this book? Whatever information lies within its pages, you may find it useful.

In order to read this book, you need a special type of ink. Lucky for you, I can make the special ink by mixing 50墨汁瓶, 10矿泉水, 30魔法石. When you spray it on the paper, you'll be able to read what's written.

When you get the right ingredients, I can make it for you. Seeing this ink used was a big treat for me, so the least I can do is help you see what's written. You deserve it.

You're not going to read the book?! This book must have something important inside...I beg you to reconsider!

Oh! You've gathered everything. I'm not sure how well this will turn out, I've only made it once you know... Hold on a second...

You haven't gathered the needed ingredients. I'll need 50墨汁瓶, 10矿泉水, 30魔法石. When you have all of them, I will make it for you!
