The source of the ghostfire was undoubtedly the black leather booklet, but there was no way the booklet could activate itself without external assistance.
The one who had truly activated it was Gleipnir.
While Angel and Laplace were both lost in their own thoughts, Gleipnir saw that no one was paying attention to the black leather booklet on the ground, so she walked closer to inspect it carefully.
Judging from the cover alone, Gleipnir truly could not make out anything.
The cover was pure black, while the words were stamped in gold. Aside from the characters "Wishbook," there were no other markings whatsoever.
Gleipnir conducted a comprehensive scan, then used astrology to confirm that the booklet was not dangerous and that turning its pages would cause no trouble. Only then did she extend her cane and open the Wishbook.
The moment the Wishbook was opened, a pale-blue ghostfire sprang out.
And that was how the ghostfire had been activated.
At that moment, both Angel and Laplace emerged from their thoughts and focused all their attention on the Wishbook.
More precisely, on the Wishbook's first page—the very page Gleipnir had turned to.
There was some writing on the first page, but Angel still could not understand it. However, he recognized the illustration on the lower half of the page.
Because the illustration depicted clusters of pale-blue ghostfire.
The ghostfires in the illustration floated in midair like Kongming lanterns, densely packed together. Coupled with the eerie facial features on the ghostfires, the image carried a distinctly chilling air.
Angel focused on the illustration not only because it portrayed ghostfire, but for another important reason.
The illustration was colored. Against the dusky, bluish-black night sky, red, green, and blue ghostfires stood out vividly.
Yet what stood out even more was a pure-white ghostfire.
