Travel Through Another World and Wake up as a Lord

When he woke up, his soul fell into a strange body. Edmund Gray, the third son of a declining baron on the border of the empire, was persuaded to leave the academy. His father died of illness and his territory was in ruins... In the Wind Valley Territory on the northwest border of the empire, a young lord who had been ignored picked up the knowledge of his previous life and used the power of this other world. So they reclaimed wasteland, opened iron mines, built roads, and trained militiamen, and gradually gained a firm foothold on the eve of the collapse of the empire.
