"It's such a lumbar cut. Li Wuding thought for a while, but decided to delineate the way of cutting by himself.

He took a piece of charcoal and drew a line diagonally in the middle of the stone, this line is exquisite, and he determines the cutting range according to the frequency range of the sound waves, which is roughly this line.

"Cut!" he waved his hand as he threw away the charcoal.

The old man stopped grinding, oiled and sawed, and the atmosphere suddenly became extremely tense.

Shi Dongdong stood there, his eyes were as wide as copper bells, and his face was tense, as if he had bought the original stone.

The saw made a steady "snort" sound, the old man's knife technique was indeed good, along the line drawn by Li Wuding, the stone was divided in half.

It was as if a watermelon had been broken open and fell to both sides, and a strange cloud of light rose up, soaring upwards until it was three feet away, and then slowly dispersed, like a cloud of mist.

The old man was shocked and said, "The spiritual light has risen three feet, it is a middle-level spirit stone!"

"I'll see, I'll see!" Shi Dongdong rushed up eagerly, and a fat face almost stuck to the section of the stone, "Wow-really!"

Li Wuding also breathed a sigh of relief, and then looked at the incision, the central area had a circle of green evenly surrounding the core area, very much like an eggshell, the core part was only the size of three fists, translucent or transparent, the texture was dense and delicate, exuding a rich aura.

This is a mid-level spirit stone!

Sure enough, it's not the same as a low-level spirit stone!

"At least you can open more than a hundred mid-grade spirit stones!" the sloppy old man also said excitedly, "Little Daoist, you're lucky!"

The exchange ratio of middle-grade spirit stones and low-level spirit stones is one to thousand, which is still a priceless exchange ratio, and the actual exchange ratio may be two or three percent higher. In other words, the original stone in Li Wuding's bet was worth at least more than 100,000 spirit stones, plus some low-grade spirit stones attached to the edge part, his income was as high as 200,000 spirit stones!

"What luck? This is vision!" Shi Dongdong shouted dissatisfiedly, "Vision, understand?"

"If he can find a similar rough stone in the next one, I believe it's vision. The old man smiled faintly, "I can let you choose two rough stones here for free." ”

With his experience over the years, the probability of the appearance of a mid-level spirit stone is only a few in 10,000, and if he can continue to "get right", he will have nothing to say.

"Okay!" Li Wuding agreed.

Then, he walked up to one of the stones he had marked earlier, and was about to speak, when suddenly his eyebrows raised and his fingers slid to the side, pointing to another stone, "This is it." ”

"I'm coming! I'm coming!" Shi Dongdong ran over excitedly, he was now convinced of Li Wuding, this kid must have found some magical method, and he must learn it when the time comes, a lifetime of wealth is not a dream!

When the stone was cut, Shi Dongdong was dumbfounded.

What kind of bullshit is this!

It's actually a piece of scrap!

It's the kind of stone that can't even be picked out of a low-level spirit stone, and can only be used as a building material!

"Could it be that Li Wuding is really right?" Although Shi Dongdong didn't say anything, he couldn't hide the disappointment in his heart.

"Come again!" Li Wuding didn't seem to give up, and bought another piece of rough stone, and also solved the stone on the spot.

This time, the calcite was decent, only the low-level spirit stone, which had risen by about thirty times.

The fruits of victory made Shi Dongdong's confidence greatly increased, and he was busy asking Li Wuding to try again.

Li Wuding looked hesitant and in a dilemma, and finally, as if he was angry, he made a lot of determination, pointing to the rough stone next to him, "This one! Uh, no, it's still this one!"

"Which piece is it!You're more decisive!" Shi Dongdong was even more anxious than him.

"Two little friends, it's late at night, are you speeding up a little?" the old man was also a little dissatisfied.

"Okay, that's it, it's the same!" Li Wuding made a "cautious" choice, which can be regarded as a choice.

"Hurry, hurry, the time has come to witness the miracle. Shi Dongdong urged eagerly.

But when the stone was cut, his face was full of great disappointment, and it was another waste stone.

"Hey, what is this?" asked Li Wuding, pointing to a strange pattern on the stone core.

"This is a stone flower, although it is rare, but it is not worth much!" said the old man with some regret. To be honest, he hopes that this young man can continue to gamble, most of his rough stones here are sold as agents, and the more he can sell, the better, and it has nothing to do with how much the customer bets. I thought this young man had some tricks, but I didn't expect it to be just luck!

"Cut it for me!" Li Wuding said. "We're here today, no more gambling on spirit stones, you can pack up the original stones containing spirit stones for us. ”

The spirit stone mine wants to be cut into a spirit stone that can be circulated, and it must be cut by an officially certified special institution, and ordinary people do not cut it, which is a bit like the national mint, Li Wuding knows this.

In addition, the scrapped rough stone boss will also be recycled, of course, the price is very low, and it can only be used as a raw material for handicrafts or building materials.

After cleaning up, Li Wuding handed the ordinary spirit stone rough stone that had been cut out of the intermediate spirit stone to Shi Dongdong, "Take it, those who see it have a share, half of each person!"

"Then how can it be done, this is a gamble you have won with great difficulty, I can't ask for it!" Shi Dongdong said in surprise.

"What's polite, just take it if you tell you!" Li Wuding finished speaking, and directly threw the big stone over.

"Thank you!" Shi Dongdong took it with a smile and put it into the storage ring.

The sloppy old man was secretly surprised, this kid is really generous, it's 100,000 spirit stones, not two jujubes!

Walking out of the dim shop, the street was already empty, and the two hurried to the teleportation station, leaving Shi Dongdong's excited shouts all the way to the empty street.

He still had the jade slip to enter and leave the academy, and Li Wuding also successfully returned to the first cultivation academy of Jinfeng Country.

When they were separated, Shi Dongdong suddenly remembered something, "Brother, where do you live?"

"I'm staying with Master for the time being. Li Wuding replied.

"I'm in the fourth class of the first grade, I come over to play when I have time, as long as I report my Shi Dongdong's name, there is no one who doesn't know!" Shi Dongdong waved his hand, "Goodbye, brother!"

"Goodbye!"

Li Wuding walked on the tree-lined path, the faint moonlight sprinkled on the path, hazy and elegant, Li Wuding was in a good mood, thinking back to the process of gambling on the spirit stone just now, the corners of his mouth unconsciously flashed a smile.

Originally, he could have swept away the rough stones that contained spirit stones, but when his finger was about to click down, his heart moved inexplicably, pointing to a rough stone mine that could not have spirit stones at all.
