"This is called Blind Street!" Shi Dongdong said mysteriously.

"Mong Cai, mango?" asked Li Wuding in surprise. It can't be such a coincidence, it's all a famous street.

"Mango, what kind of fruit is that, can it improve cultivation?" Shi Dongdong asked strangely.

"You can satisfy your crav......ings," Li Wuding said here, he couldn't say that this thing was rich in vitamins and fiber, which was good for ...... , well, don't talk about it, the little fat man won't understand it.

Seeing that Li Wuding stopped talking, Shi Dongdong explained, "Blindness is the blindness of a blind person, which means that even a monk is similar to a blind person on this street. Gambling on spirit stones has little to do with the level of cultivation, and the divine sense can't penetrate the spirit stone mine anyway, so it almost only depends on eyesight and luck. You don't know, there are more mortals than monks who come here to gamble on spirit stones, and monks and mortals are fair here!"

I see!

It's all blind people touching stones!

The two wandered along the dark streets, unsure of which one to go to. The best time to gamble on spirit stones is noon, when the light conditions are the best, this time has reached the evening, basically there are no customers, some shops are open, purely because the boss eats and lives in the store.

"This is it!" Shi Dongdong suddenly pointed to a very inconspicuous small shop in the mountain col.

Not only is the small shop remotely located, but the entrance is unusually narrow, allowing only two people to enter and exit side by side, the door is crooked and crumbling, and a broken lantern dangling in the wind hangs in the doorway, which looks dilapidated in the dim light.

"This can't be a black shop, right?" asked Li Wuding uneasily.

"Hehe, this kind of place is easy to pick up leaks!" Shi Dongdong smiled slyly, "Our family is in business, and there are many doorways inside, and a small shop like this that is not patronized by many people is the best place to gamble on spirit stones." ”

It turns out that after the raw stone of the spirit stone mine is mined, it is necessary to go through the preliminary screening of the mine head on the site, and the rough stone that is thought to contain the spirit stone is selected out, and the remaining rough stone is of very low grade and of little value, and is purchased by the next level of businessman.

For example, Li Wuding absorbed and collapsed a room in the Royal Library of the Beihai Kingdom, and he used this low-grade spirit stone ore rough as a building material.

The two cautiously walked into the dark shop, and there was not a single birdman who couldn't see it, but Shi Dongdong was not in a hurry, he opened his throat and shouted: "Boss, boss, come out to pick up customers!"

After a while, a sloppy old man came out of the side door, holding a copper kettle of warm wine, and asked impatiently, "What do you want to see?"

"Of course you want to bet on the spirit stone, are you still in the hotel business here?" Shi Dongdong said confidently.

"Pay a deposit of one hundred spirit stones per person. The sloppy old man said lightly, and then spread out his greasy palms. In his opinion, most of the money that the two little hairy children can have is to run here to fool around.

I'll go! I have to pay a deposit when I enter the store, and it's a hundred spirit stones! Li Wuding's eyes widened in surprise.

"That's the rule. Shi Dongdong was not surprised, his hand flashed, and he took out a handful of spirit stones.

The old man nodded with satisfaction, his face looked much better, "Please come with me!"

Walking through the winding corridor, when a door was pushed open, Li Wuding was surprised to see that his eyes were a wide cave, and dozens of moonstones were lined up on the huge dome, illuminating the cave as if it were day. The area of the cave is about two or three acres, and countless large and small stones are neatly placed on the ground, the large rough stone is as high as two zhang, and the small one is only the size of a sea bowl.

"Look at it yourself, you understand the rules, except that you can't destroy the rough stone, you can look at it however you want, there is a price on it, and if you like it, you can bring it to me!" After the old man finished speaking, he leaned back on a chaise longue next to him, picked up the copper kettle, drank it to himself, and never looked at them again.

Shi Dongdong rushed in impatiently, skillfully touched and looked around the primitive, and then took out a small trumpet-shaped thing, and stuck it on the rough stone to listen to it, which was very professional.

Li Wuding felt curious, so he followed, watching him toss from the sidelines.

After looking at it for a while, he didn't see a doorway, so he casually picked up a rough stone the size of a skull and observed it. Sure enough, each rough stone was marked with a number, and this rough stone was written with a "nine", which means that nine spirit stones are needed to buy this rough stone!

It's so expensive! Nine times out of ten, there are spirit stones in it?

Otherwise, who would have entered the water in their brains and spend nine spirit stones to buy such a stone?

He tried to infiltrate with his divine sense, but it was useless, which was expected, otherwise, the monks who were not eyeing the monks here too early would have been swept away.

See what the shape has to offer?

Can you use the big data algorithm of artificial intelligence to find some rules?

Along the way, hundreds of pieces of data were collected.

Ding——

Big data has calculated a pattern!

Sure enough, it's AI, it's a cheat!

Li Wuding looked over in surprise.

I saw a line of conclusions come to mind: the bigger the original, the more expensive it is......

Malegobi's, what kind of bullshit is this, is this how people sell it!

......

"It's gone! This rough stone must contain spirit stones, maybe it is still a medium-grade or above spirit stone!" Suddenly, Shi Dongdong's exclamation resounded throughout the cave.

Li Wuding followed the sound and looked at him, only to see that he was dancing around a rough stone half the size of a table, overjoyed.

He hurriedly walked over, looked east and west, it was just a dusty stone, didn't he think there was anything special?

Looking at the price again, I'll go - ask for a thousand spirit stones!

"Are you sure?" asked Li Wuding, touching the stone.

"Of course, with the experience I have accumulated over the years, this rough stone must be rich in spirit stones, and according to conservative estimates, at least about ten thousand spirit stones can be cut, and maybe there are medium-grade spirit stones!" Shi Dongdong said proudly, his chubby little face squeezed his originally small eyes into two small mung beans, but he couldn't help but shine.

"You still want to bet on spirit stones?" Li Wuding said in surprise, originally he thought that Shi Dongdong was just thinking of coming here to fight on a whim.

"Of course, my father is so good, he often comes here to hang around, buddy has followed him since he was seven years old to gamble on spirit stones, and he can be regarded as well-informed, and he has developed a pair of fiery eyes, and buddies rarely hit the eyes!"

"Any tricks?" asked Li Wuding.

"Of course there is, this is my family heirloom, you don't want to spread it!" Shi Dongdong said, "You don't need to look at the spirit stone, you have to listen!"

"Listen to what?"

"Listen to different voices! Of course, what kind of voice is right, I can't tell this clearly, I have to rely on myself to understand!" Shi Dongdong said mysteriously.

Listen!

Li Wuding's heart was shocked, yes, the vibration frequency of matter of different densities is different!

The rough stone can't be seen through, but there is always a difference in density, as long as the big data is collected on their vibration frequency, can't you tell the difference!
