Becoming a City Lord in Another World

Lu Yu transmigrates to another world, where he can travel between two realms and has an internal space with him at all times. At first, all he wants is to be a quiet middleman. But after he reluctantly trades a glass marble for a city, his path to becoming a city lord spirals out of control.

Lu Yu's Chang'an grows from a remote frontier town into the most prosperous city in the other world.

Sweet potatoes, corn, and potatoes mean there is never a famine in Lu Yu's territory.

With blast furnaces and steelmaking techniques, Lu Yu's army is invincible.

The king: "Send the princess there to marry him. We have to steal his technology!"

The princess: "For the good of the country, I don't mind making a sacrifice... Lu Yu is so handsome!"

Beastfolk: "Lord Lu Yu is the most refined and gentle noble I've ever met. With him here, we can build a wonderful home."

This is a wondrous world where cold weapons and magic coexist, with adorable cat-eared beastfolk and the mysterious elven race of the north...
