The Knife Bearer in the Long Night

There is a book in Wedge · Book World. It has no cover and no signature. The pages are yellowed and the ink is old. It looks like it has been turned over and closed a thousand times. There are only names in the book. No birthday, no place of birth, no notes. Just the names, written one after another, from the first page to the last page, densely packed, some are so blurry that they can't be seen clearly, and some are so new that it seems like they were written just yesterday. It is said that whenever trouble comes, an additional name will appear in the book. It is said that those whose names are on the book will not live long. It is said that the owner of the last name will personally end the troubled times that put him on the list. No one knows where this book is. No one knows who is writing it. In the sixteenth year of Jianing, three days before the winter solstice, snow fell. In the capital of Liang Kingdom, somewhere in an unknown room, a hand held a pen and wrote a name on the latest page of the book. Before the ink was dry, the snow outside the window was already three inches deep. That name is - Gu Changye.
