The young mages quickly left, and Xander frowned and shook his head as he said: "Eh, you guys. How can I say it? You guys are my elders, but you have to use your brain! Where is Oakland? A bunch of bumpkins live there. How can they create such potions? How much did you pay?"
"One..." The elder mages blushed and murmured, "One gold coin."
"One?" Xander smiled helplessly. "One gold coins? If a potion that is worth a gold coin can help you to advance, then I will let you guys use my head as a soccer ball!"
Xander turned around and went up the stairs furiously. The four elder mages looked at each other and then returned to their rooms to drink the potion to try to advance.
After a minute... One of the elder mages rubbed his stomach as he quickly rushed to the washroom. A female mage who was in charge of reception saw this and sneered, "You will get a stomach-ache when you drink unknown potions."
