Liu Feng unexpectedly has the ability to travel back and forth between other worlds, and also has an inner space, acting as a second-order dealer in two worlds. When he bought a city in another world with a glass from the earth, he began to live as a nobleman as a city lord in another world. This is a cold-weapon and wonderful otherworld. The cat-eared girl, the fox-eared girl, the rabbit-eared girl, and the elf princess that have never been seen on earth… In this other world, Liu Feng can see it at any time. Princess: Liu Feng's city is the happiest city in the world. Princess: I absolutely want to move in, even if I give up my status as a princess. Bachelor: The technologies and concepts used in Liu Feng's city are a thousand years ahead of the world. King: There is the tallest building in the world, where the strangest things in the world gather, and there is the richest and most magical city in the world.
