Age of Calamities

Dying when I killed the possible thief who entered to my house, it put into action the destiny that made me reincarnate as the second son of a noble family. I wanted to learn magic, it turns out that I am cursed and I can't even though I have great reserves of magic power, that didn't stop me from following the path of a warrior in order to awaken the aura. All to fulfill my stupid dream of being a man of a single army, while on the way I manage from my home the progress of my lands that I have as heir where I plan to live the rest of my life. Apparently, this is the era of calamities because the monsters began to change and become more dangerous, apart from the discovery of another enemy kingdom that is attacking from the coasts with firearms and other humanoid monsters invade the unprotected villages. When we had already explored those areas and we knew well that before there were such civilizations in those places.
