Rise from a Young Lord

The protagonist dies suddenly at home and is reborn as a minor nobleman. Or a noble from another world. This different world is somewhat similar to the Western Middle Ages where lords and knights dominated everything on the continent. In this magical world, there are giant dragons and elves, knights practicing fighting spirit, and mysterious magicians. Even the protagonist himself has cultivated basic fighting spirit and become a knight who meets the enemy. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
