In Ningcheng, emotion is a malignant tumor that needs to be removed. Memory Weaver Lin Mo is the best surgeon in this city of reason. His duty is to penetrate into people's brains and remove all joy, anger, sorrow and joy. Until one day, a sad memory that belonged to no one haunted him like a ghost.
In order to trace the source of this forbidden emotion, he sneaked into the dark underbelly of the city and met Yiyi, a girl exiled by order. She reveals to him a cruel truth: the so-called purification is a scam that has lasted for hundreds of years. The peace they rely on for survival is based on countless harvested souls.
When the foundation of faith crumbles, the former defenders are forced to become the only rebels. He must turn against the world and embrace everything he was taught to hate. Because the only weapon to awaken this sleeping city is human nature itself.
