Sitting at his office desk, Nyx and Ryan were reading the book "Secular Stories of the year four thousand seven hundred". With each translated page, the two exchanged confused glances and made more notes.
<So this book has two purposes...>
'But why would they hide magic in a demonic history book?
<And why would they hide demonic stories in a book of mythology of the northern kingdoms?
'At least this is slowly making sense'
<At least to you. I'm sure I haven't spent more than fifteen hundred years imprisoned, and if it's the year four thousand seven hundred, and this book is considered ancient, the second world is advancing faster in time>
'And how could you possibly know the time in your head?'
<Your mana is like an hourglass, it always increases and decreases at the same frequency. If you don't have any evolution in your mana, it is possible to calculate the time needed for it>
'Using mana like a clock. Interesting'
