The Last Banker of the Dragon Clan

It's the end of the world. The dragons are gone, the dwarves are gone, the elves are gone, and the humans are gone. But one bank is still open. Dragon Savings and Trust Bank, only window: Gwen. Yinlong has four hundred years of service and has never taken any annual leave. A goblin came that day and wanted to redeem the reverse scale that grandpa had saved. Gwen dug out the terms: Please pay a complete human soul. Goblin: Humanity has been extinct for three hundred years! Gwen: That's your problem, not the bank's. Here comes another human girl who wants to save a dragon embryo. Gwen: What is your business? Girl: Current account. Gwen: The current interest rate is 0.5%. Girl: Can you be higher? Gwen: You are saving embryos, not gold bars, and the risk premium is high. Another Abyss Lord comes and wants to save his true name. Gwen: Fixed term or demand deposit? Lord of the Abyss: Regularly, ten thousand years. Gwen: The annual interest rate is 0.01%. At maturity, you can get back one name plus 36 cents. Lord of the Abyss: ... Are you devils? Gwen: We're bankers. The devil doesn't issue invoices. Finally, the Rose Monarch came to withdraw the deposit, and Gwen took out the interest rate manual: seven-day period, negative interest rate of 300%. Rose Monarch: I save! Gwen: Okay, you owe me three of yourselves when due. Rose Monarch:? ? ? Gwen (smiling): Welcome to complain, welcome to cancel your account, and welcome to visit next time. ——The story tells us: The end of the world is not scary, but signing a contract with a banker is scary.
