His Majesty and Two Bags of Rice

Emperor Wu glanced at Chen.

The young man had no idea how close he was to death. He told Emperor Wu, "Enough chit-chat. Here's how you play: They're giving out ten rounds of gift envelopes at 15-minute intervals.

"All envelopes contain vouchers, and they represent various gifts. Some can be exchanged for silver and gold coins, and others can give you spiritual stones, condiments, and food! You can cash them in right here and take everything home with you.

"Do you know what's the most important prize?"

Emperor Wu asked, "What is it?"

"It's a collection of eight words!" Chen said excitedly. "On the back of each voucher, there's a word. There are eight different words in total, and if you can find all eight of them, you can exchange them for 999 silver coins!"

Emperor Wu said, "That's a lot."
