I Have a Store in Xinghai

"What is it like to have a store that allows you to travel around the universe and sell anything as long as you give it money?" Li Ling: "There's no special feeling, it's just living a small life selling goods to make money when I'm short of money, and traveling around the universe when I'm rich." "Is there nothing else besides this?" Li Ling: "Emmm, occasionally I explore black holes, travel through space cracks and wander through dimensional spaces. Oh, by the way, I have also saved several civilizations that were on the verge of extinction." "But it is said that you took the opportunity to extort a lot of money from those civilizations." Li Ling: "Well, I am a businessman. Can what a businessman does be called extortion? This is clearly a transaction, and of course there is a fee for the transaction! Let me reiterate, I am not extorting!" … To put it simply, this is a story about making money and wasting money in the universe.
