In a future world where memories can be retrieved, traded or even erased, history is fractured and identity remains a mystery. People rely on memory crystals called "Yi Crystals" to learn, work, and even feel happy.
Lu Ming, a top "memory hunter", can easily sneak into anyone's mind and steal the most secret memories, but he can't find his own past. He is like a ghost living in the present, repeatedly haunted by a dream that does not belong to him.
A mysterious commission pushes him to the center of lies and conspiracies - looking for the legendary "Zero Memory Crystal" that can subvert the world. From the ruined city soaked in neon to the floating city with domes hanging high in the sky, every step is on the edge of life and death. What pursues him is a giant group that controls everything and a ruthless enemy who knows his past; traveling with him is a mysterious woman who carries a blood feud.
When the lost memories came flooding back, he realized that the truth he was pursuing was enough to pay a price that the whole world could not bear.
How will he choose this time? Embrace the false tranquility, or bear the weight of reality?
