In this world called the "Unforgettable World", death is not the end, but another form of remembrance. From the first cry of life, each person's words and deeds, every smile, love and hate, merits and demerits, will be like an invisible carving knife, leaving an indelible and unforgivable mark on the bones in the flow of time. This is the "Bone Book" - an absolutely true personal epic written by life itself. It silently accompanies everyone's growth and aging until breathing stops.
When the fire of life is extinguished, the bones carrying all memories and experiences will be sent to the sacred place-Guizhen Hall. The "engraver" with special talent and power uses the pure "inscription power" in his body to imprint the subtle imprints on the bones that ordinary people cannot decipher. Under the catalysis of the pure fire, the liquid memories and experiences flow, gather, and solidify under the joint action of the inscription power and the pure fire... And finally turn into thick books with a warm luster - bone books. This is the final and most complete answer to life.
The bone book is the truth, and the truth is the iron law.
This is the cornerstone of the Bone Inscription Realm that has operated for thousands of years, and it is the creed that the inscription masters have guarded throughout their lives.
People have great faith in bone books.
No one knows that this seemingly indestructible cornerstone of "reality" has cracked a gap leading to the endless abyss. The guardians, however, have not yet noticed this deadly whisper from the shadows.
