In the Purification Society, the inmates hunt down evil spirits in exchange for pure thoughts. Those who rank lower will be expelled and become "empty shells" whose consciousness is forever trapped in the evil realm.
Xu Yandong didn't want to owe anyone, so he always walked alone - he took on tasks alone, walked into the Evil Realm alone, and came out alive alone.
Until he discovered a fake core made up of countless fragments of ember cores in the underground evil realm of the flea market in the south of the city.
