- Description from Novelupdates

Steven awakens to a nightmare. Transported to a brutal medieval kingdom on a faraway world, he wakes up as Kivamus, the exiled third son of a Duke. Now he’s the newly made Baron of a crumbling village called Tiranat, in a bandit-ridden frontier located within untamed forests. Here, survival is a daily battle, resources are scarce, and technology is a distant dream. Yet, he sees potential where the villagers only see struggle. He dreams of using his knowledge to forge a new future for Tiranat, a future fueled by industry. But the path to progress is not going to be easy. Managing a starving village in the coming winter and navigating the cut-throat world of medieval nobility is just the beginning. This is a slow-progression kingdom-builder story, with a lot of focus on worldbuilding and eventually, industrialization and tech-uplifting. The story is going to be very, very long. Settle in for a slow-burn slice of life, where the journey is just as important as the destination. Welcome aboard!

It was only after Su Yayan's death that she realized that she was a malicious cannon fodder female character who became a scapegoat in a Mary Sue story.
