Just Kill the Big Dragon

At first, disasters were rampant and strife spread across the land, but I eliminated the suffering and became a lord, shepherding and guarding the land. Later, when the orcs rose and the royal family fell, I went to play chess with the emperor again to save the continent from the flames. Now that the big dragon is attacking, and you are begging me to slay the dragon, I am the only one in the entire continent who can fight it, right? Okay, wait, after I finish cracking my attribute panel, I will go and solo the big dragon! —————— The story of traveling to another world, conquering the world with an attribute panel, and killing dragons.
