Merchant From Earth in the Magical World

My name is Yan Xing, an Earthling who can freely travel between Earth and a magical world.



Elves like the silk I bring them and also enjoy the longbow rockets I provide.



Orcs appreciate the soap I bring them and also fancy the Roarer tanks I supply.



Even human nobles, amidst their frenzy for pristine porcelain, install magnetic coils in their estates.



Even the Undead hope to order a top-notch coffin set from me, to catch up on horror series during sleepless nights.



One day... Angels, dragons, and demons found me.



I told them, "My market is open to all races and creatures. How about a few portable Doomsday Judgments?"
