'Amazing,' the old man commented, 'your luck is really great tonight,' he laughed and his words and laughs didn't help to explain anything to Jim.

"Oh… so these sparkling little stars are all ores?" Jim was tempted to enter but he kept his place while checking every single corner illuminated by the light.
'The cave looked safe,' the old man said, 'and you need to hurry and extinguish that light or else you might not only draw monsters but also couple enemies alongside them.'
