A bottle of ancient document preservative from a mysterious ancient book restoration room allowed modern cultural relic restorer Lin Wan to accidentally travel to the Western Fantasy Continent and become the countess of the frontier land—Iseline Lin Wan.
What she inherited was not only the noble title and the white frost castle with snow falling all year round, but also a "Soul-Eating Book" that feeds on living creatures. This book is both a curse and a power - only by sacrificing living beings can it maintain its existence, otherwise it will come back to bite its owner.
What's even more troublesome is that her beautiful but dangerous count husband, Adrian, seems to have already noticed something strange about her.
In this borderland where ice and blood intersect, when the truth is revealed, is she Lin Wan from another world, or is she... Iselin who has been chosen long ago?
Intention: Go both ways
