Among the mysterious items, the first thing Zuo Yi chose was a book.
The book was roughly the size of a sixteen-mo volume and five centimeters thick. Its dark purple cover was sturdy, embossed with dense and intricate pale gold patterns. It looked exquisite and beautiful.
But there was no writing on it whatsoever.
It contained a total of twenty-seven pages, all of them blank. They were made of a parchment-like material, with faint textures visible upon close inspection, and they gave off a very subtle sandalwood fragrance.
The back cover was not much different from the front, except for a coin-sized emblem in its lower right corner.
The emblem consisted of a star and moon design.
According to the records of Princess Eileen, the "human archive," this book had come from some ruins in the Elven Kingdom. It had been unearthed by adventurers, eventually made its way to Celes, and was collected by a member of the royal family.
Like the other mysterious items, no one could identify its purpose or origins. Yet neither raging fire nor strong acid could damage it, and it was even impervious to slashes from blades and swords.
Moreover, even if it was damaged by the impact of powerful force, it could slowly repair itself.
Therefore, despite having been unearthed many years ago, the book still looked brand-new.
Zuo Yi knew that this was a Wizard Book.
A Wizard Book was a wizard's equipment, and its purpose was to seal spells.
Every wizard's power was limited. Once that power was exhausted, they could no longer cast spells. With a Wizard Book, however, their endurance in battle could be greatly enhanced.
More importantly, spells could be cast through a Wizard Book with incredible speed, making it a formidable tool for both offense and defense.
