Too Much Money
"T-Thank you, Manager!" Mei Xing accepted the spirit stone with a bright smile on her face, and then she bowed to him.
"I promise you that I won't betray your trust!"
Su Yang nodded, "Go home. I will see you again tomorrow."
Mei Xing then left the massage parlor, but since she still had plenty of time before midnight, she decided to visit an exchange store to see how much the high-grade spirit stone was worth.
These exchange stores were known as Spirit Stone Grand Exchanges, and people can exchange their spirit stones for a different grade of spirit stones. For example, one could exchange a single medium-grade spirit stone for 10,000 low-grade spirit stones, or they can exchange 1 low-grade spirit stone for some mortal such as silver and gold.
Fortunately for Mei Xing, she didn't have to travel far to find one of these stores since there were multiple of these stores in every district.
