This novel is getting better. The story is more intriguing. So many new information is being revealed. New allies are presenting themselves. Enemies are infighting. So many buried secrets are being revealed. The battle for the Empire is coming strong in the next volume.
Imperial Reincarnation v3 remains an intriguing series, much plotting and strategizing behind the scenes, and in a way that feels believable. Merely being crowned doesn't make you a true emperor, and becoming a true emperor means preparing for a battle both literal and at court. The story remains an uncommon kind of story for light novels, let alone isekai. Not often that being a powerful spellcaster will not save the day. Still, it would be somewhat better with less information dumps and a bit more speed to the plot.
