Nation-Building Starting from a Dragon Knight

I don't know why or for what reason I was reincarnated into this world. But living as a slave isn't interesting, and more than anything, I don't have the will to live even until tomorrow. While spending such monotonous days, I happened upon a dying nobleman wearing the flight suit of a Yusbell Dragon Knight Academy in front of me. Seeing this situation as almost a divine revelation, I abandoned the dying nobleman to his own devices without helping him, and I switched places with him. The nobleman's name was Robert. From today on, I will live as Robert Steuif Du Striker. Well, not knowing when I'll die, let me live enjoyably. Chapter 1 is about infiltrating the Dragon Knight Academy. Chapter 2 involves going to the lands I've come to manage and building industries using modern knowledge. Chapter 3 involves rushing about to extinguish the sparks that have spread to the west.
