Liu Ming and the few others who had come with him exchanged hesitant glances.
All being independent cultivators, thirty thousand spiritual stones was no small amount to them.
"Here are thirty thousand spiritual stones," Liu Ming said.
With a flick of his wrist and an expressionless face, Liu Ming tossed over a small cloth bag.
"This friend sure is decisive." The middle-aged man waved his sleeve, snatching the cloth bag with a sweep, scanned it with his divine sense, and for the first time, he nodded with a smile.
"This is a spirit disc used for timekeeping, which can calculate the time you stay in the prairie. These thirty thousand spiritual stones cover the cost for one year. If you exceed one year, you'll need to pay extra spiritual stones upon leaving," the middle-aged man explained, after tucking away the cloth bag and handing a white jade disc to Liu Ming.
