Loved Jing Ye and An Nuo and the relationship between Dr. X and An Nuo, but the ending felt rushed. Unless you read Song of Reverberation, you wouldn't understand the lore of this world and even then the lore in SoR wasn't explicit. This story had a lot of potential and probably should've lasted 80-100 chapters like SoR to have been fully fleshed out, but alas, it is only 41 chapters. It was slightly disappointing.
