Human memory is a lamp oil. If someone ignites it with secret techniques, they can reveal the hidden truth - each layer illuminated will permanently burn away the same amount of memories. It is this "Ember Lantern Technique" that wandering warlock Shen Xi practices: the more he pursues the truth, the less "self" he becomes.
A serial murder case in Yunling City brought Ji Changming, a swordsman who was looking for the truth behind the family's destruction, before him. The sword in Ji Changming's hand was sharpened for revenge, and the lamp in Shen Xiang's hand was lit for the pursuit of truth. The two were forced to go together, but found that all the clues pointed to a massacre that was wiped out by the court 80 years ago, and a mysterious organization "Wu Ming" whose name is "burning all lies."
When Shen Xi illuminates the truth at the expense of memory again and again, he begins to forget the face of his old friend, his own origin, and even the reason for his companionship. And Ji Changming did the most stubborn thing in the world - he opened a notebook and wrote down every word Shen Xi said day by day: "If you forget, I will remember it for you."
Martial arts, fairy tales and suspense reasoning are integrated here. Each volume contains a case, but the hidden thread is that the extinguished memories are burning out layer by layer like lamp oil. At the end of the twenty-volume volume, he did not remember most of the people, but he remembered that someone was remembering it for him under the lamp. And on the top of the lampstand mountain, he saw the sky - the second light was on.
Intention: The meaning of truth lies not in being seen, but in someone remembering to see it. Memories can burn out, but the obsession to remember each other will never die.
