MTL - There is Room For a Beautiful Daughter-in-law In the Rebirth Era - Chapter 816 why are you here

We have all heard the legends of great wizards, but do we know how those stories begin? Ardan Egobar, a young man living in a remote corner of the New Monarchy Empire, does not. He doesn't realize that this story is about him. Not yet...In a world where steam locomotives chug along iron rails, where massive airships hover in the skies, where in the cities you might encounter orcs in suits involved in organized crimes, dwarves with cigars controlling major banks, or elves strutting down fashionable boulevards, where humans have built vast nations on the brink of a world war, almost anything seems possible.Maybe, in such a world, even an ordinary young man, the last of the mountain hunters, might one day become the greatest wizard in history.

Xiao Yu, who was a student from modern Earth, accidentally transports to another world and becomes the lord of a territory. Facing an unfavorable situation, he vows to take back his family business, build his new territory, kill all of those who covet his wealth, and dominate the world!
