Welcome to Darkos Exchange

There is a place in this world where you can buy anything. It can satisfy anyone's desires, allowing people to use their lifespan, feelings, treasures, and even their souls as bargaining chips to buy what they want. It doesn't require any special search. As long as you have a big enough desire, you will come to that place involuntarily. When you walk in, a meeting person will appear in front of you. This person always speaks to you with a humble and gentle smile. "Welcome to Darkos Exchange!" "Excuse me, what do you need?" This novel and its characters are purely fictitious.
