"Young man, is this your first time to aikenxing?" the man who opened the stone for him was a middle-aged man, who looked very talkative and very neat. "Aikenxing has many such small shops, and the places where the stones are produced are different, but our shop is absolutely the highest quality, children and old people are not deceived!"

"Is there any fake stone?" Jin Shou asked curiously.

"Of course, the probability that gemstones produced in some barren areas can produce things is very small. Many profiteers will sell those worthless stones as stones in high-quality areas," said the middle-aged man. "However, local people will not be fooled. Only tourists who come for the first or second time will be deceived by their cheap prices."

"Why? Doesn't it mean that this kind of stone doesn't look any different from the outside?" Jin Shou quarreled with him while watching the man open the stone.

"There are still a few differences. The light spot on the stones produced in barren areas will be very dim, which is a sign of energy depletion. Even if there is nothing in high-quality emeralds, they are good energy substitutes, because they contain a lot of high-quality energy," the middle-aged man explained to him, "Most of Aiken's vehicles rely on the energy transformed from emeralds."

Jin Shou nodded suddenly and stared at the stone in the man's hand without blinking.

"Good luck, young man. It's a good start!" after a few minutes, the machine slowly grinds away the isolation material in the outermost layer of the emerald, revealing the green brilliance and a mass of white liquid wrapped in the green translucent stone.

"What is this?"

"This is the energy stock solution, which can be regarded as a high-level thing in the energy liquid," said the middle-aged man with a smile. "This thing is small and has high energy. Most spaceships like to use the energy stock solution as fuel. I think you can sell at least more than 100000 star coins!"

It only takes 1000 star coins to buy and open a stone here. Jinshou opened this stone, which is equivalent to making more than 100000 directly. It's really lucky.

"Young man, buy some more! I seldom see tourists coming for the first time. There are things on the first stone!" the middle-aged man said enthusiastically, "I still have emeralds from star babies. Would you like to open one?"

Jin Shou nodded and took a heavy piece from the pile of emeralds.

"At first glance, you are really a new tourist." the middle-aged man took the stone and couldn't help laughing. "This relatively heavy stone often produces good things. Real experts like to choose small and light ones. After all, emeralds are weighed by kilogram. Although small and light gemstones produce few things, they have a great chance. Young man, you don't want to change another one!"

Jin Shou saw that he didn't keep anything from himself. He couldn't help but have a good impression on him. He quickly shook his head and said, "forget it, just this one. It doesn't matter. I'll buy a few more pieces."

The middle-aged man nodded, put the heavy Emerald on the machine and let the machine work slowly. He ran to the house and brought a cup of tea to Jinshou.

Jinshou slowly tasted the Qingxin tea produced by aikenxing, while watching the machine slowly grind away the gray matter on the top of the emerald.
