People Are in the Heavens, Doing Business in All Realms

The time traveler Si Chen found that he seemed to have traveled to the [hub] of all heavens and worlds. Every once in a while, he can meet visitors from the worlds such as Qin Shi Mingyue, Tang Shuanglong, Dou Po, Douluo, Immortal Sword, Zhu Xian, Marvel, DC, SCP Foundation... Etc. Therefore, in order to maximize the effectiveness of his golden finger, he decided to make good use of the characteristics of the "main world" [hub] to start a small business. "What does it mean that I bought at a low price and sold at a high price? Isn't it reasonable for a merchant to make a small profit during the buying and selling process?" "How can you say that I saw your demand and raised the price temporarily? Isn't it strange that the price of goods fluctuates due to various reasons?" "And I didn't force you to buy or sell. If you think it's expensive, you don't have to buy it... Putting aside the fact that the item is still the same item before and after the price change, just ask whether the higher purchase price makes you cherish the hard-earned items in your hands more!" Si Chen spoke plausibly in the face of the unscrupulous customers who did not know how to reflect after he was hung on a street lamp and only accused him of running a black shop.
