In the cold steel city "Sky City", human souls have become a commodity that can be traded. The consciousness after death was uploaded to a server called the "All Things Spiritual Realm" and became the cornerstone of the giant corporate "Bianan Group" that rules the world.
Ling Su, codenamed "Ye Crow", is the top "scavenger" of the group. His job is to dive into the ocean of data and erase the remnants of consciousness known as "contamination." He was calm, numb, and his hands were covered with the "reverberation" of digital souls, until he encountered "Zero" during a routine mission.
"Zero", a data ghost that should not exist, a pure consciousness born in the ruins of billions of souls.
An order, a disobedience. Turn the Ace Scavenger into the most wanted criminal. In order to protect this invisible life, Ling Su was forced to become the enemy of the entire world. Caught between order and chaos, he will dance with desperate hackers, mysterious bosses, and his tampered memories.
When the truth of "eternal life" is revealed, and when the prison of the soul emits an overwhelmed cry, he must make a choice: pull the trigger to cleanse the world, or become the first spark to ignite the ruins?
This is a story about memory, humanity and resistance. In an era when the soul can be formatted, a man decides to find his heart.
