No Matter What, There Shouldn't Be Dragons in This World

I took my sister out on a treasure hunt and accidentally picked up an elf loli - a humanoid weapon. I made her my daughter, but my fiancée didn't know... By the way, I also have a bunch of maids and a manor. The careless young master was finally captured by his servants - my servants can't be so violent. (Actually, it's not a cool article) This is an extraordinary setting in everyday life, coming from the distant future, the future world after everyone's death - in fact, it is a setting deliberately made out of fear of harmony. There are only two countries left in the world, One that lives on land is called a land empire; There is a floating city in the sky called the Sky Federation. Our story begins with a treasure map held by a servant in a mansion in the land empire... So, who can shoulder the fate of all mankind?
