I flew on a sword at the magic academy

It wasn't that the double pupils' eyes made a mistake, but rather that the gambling was a fake. They stored some ordinary stones and raw stones containing spiritual stones in a sealed room. After years of nurturing, they imbued those ordinary stones with a trace of spirituality, thus misleading the public.

The raw spirit stone has a very special outer layer that can obscure the secrets of heaven, making it impossible for people to perceive its true nature using divine sense or other means.

Even the double pupils nurtured within Shi Daohan's body could not directly see through the essence; they could only capture a trace of spiritual charm.

Shi Daohan used this method to determine whether there was any treasure inside the stone, but he was unexpectedly tricked.

Of course, she felt that this was because the ability of that double pupil eye had not fully recovered. If the ability of that eye were fully activated, it should still be able to directly see through the essence.

"Damn unscrupulous merchant!" Shi Daohan cursed inwardly. He had no integrity whatsoever, because deception was truly despicable.

During the subsequent stone selection, Shi Daohan carefully examined the stones and discovered dozens of ordinary stones that were indistinguishable from the real ones. It was only because she possessed the eyeball of someone with double pupils that she was able to avoid being ripped off today.

Finally, she chose a rough stone the size of a human head, which was covered with cracks and looked extremely ugly.

When she chose this rough stone, many people around her sneered.

"Hey young man, do you even know anything about appreciating stones? You managed to pick such an obviously worthless rock. If you have too many spirit stones, you might as well just give them to me. There's no need to be such a sucker!"

"What an idiot! It would be a miracle if this rough stone could even be sold."

Everyone shook their heads and mocked, thinking that Shi Daohan was just an outsider who knew nothing.

Despite the sarcasm and ridicule around him, Shi Daohan remained unperturbed, simply smiling and saying, "I truly don't know anything about stone appreciation, but I think I'm having pretty good luck today. Perhaps I really will cut something out of it?"

"What a silly boy!"

"If you gamble away all the spirit stones your family has saved up over a lifetime, I wonder if you'll jump into the river and commit suicide."

Shi Daohan ignored the noise and troubled the master craftsman in charge of cutting the stone. He used his hands as a knife to peel away the layers of stone skin.

"I think we should just cut it in half. There's no way we'll get anything out of it anyway, it's just a waste of time."

"If this piece of junk could be sold, I'd swallow the stone skin whole."

As the rough stone chosen by Shi Daohan was cut smaller and smaller, the surrounding mockery intensified.

But just as the rough stone was cut into pieces the size of lychees, a dazzling light suddenly shot out.

The rich spiritual energy felt like a gentle breeze, making every pore on my body open up and leaving me feeling completely relaxed.

A light blue glow emanated from the stone, accompanied by wisps of smoke. Everyone was astonished; it was clearly a successful shipment, and judging by its appearance, it didn't seem to be an ordinary spirit stone.

Shi Daohan peeled away the last layer of stone skin, and a piece of azure stone appeared in her hand. It was only the size of her thumbnail, but it exuded a breathtaking glow.

"This is way too small!"

"It's only the size of a fingernail, what value could it possibly have?"

Those who had just exclaimed in surprise came to their senses. Although the goods had been shipped, they were far too small. What use could they possibly be?

"This is aquamarine!" The experienced stone cutter exclaimed in surprise, but quickly shut his mouth.

If Shi Daohan were someone who didn't know its value, their jade gambling shop could have bought this piece of aquamarine from her at the lowest possible price.

Shi Daohan chuckled softly, presenting the tiny stone, no bigger than a fingernail, to everyone. "This is aquamarine crystal," he said, "an extremely rare and precious material for forging weapons. I'm sure some of you are knowledgeable about it. What do you think this piece of aquamarine crystal is worth?"

"It's actually a piece of aquamarine crystal. Although it's small, it's still worth five hundred low-grade spirit stones."

"That's outrageous! She even managed to cut out aquamarine!"

Some of the people around were indeed knowledgeable about the product, and they all showed expressions of envy.

Although aquamarine comes from the deep sea, with the changing times and the transformation of the sea into mulberry fields, it is not uncommon for it to be cut out from the raw stone.

If you're lucky enough, it's not impossible to cut out an ultimate holy weapon.

In the world of gambling, one might occasionally unearth a rare source with unpredictable and extraordinary power, whose value is immeasurable, but such sources are rare indeed.

"I think I just heard someone say that if they can get the goods, they'll swallow this stone skin on the ground whole. I wonder if that still counts?" Shi Daohan said with a smile.

Upon hearing this, everyone around fell silent. Only a fool would stand up and admit it.

Shi Daohan turned to Lin Hong of Cangyu Residence and said, "Aquamarine is a rare divine material for refining weapons and forging artifacts. Although there's only a little bit, it's still worth five hundred spirit stones. I wonder if this brother can afford to compensate for it?"

For those present, five hundred spirit stones was a considerable sum, and anyone would feel the pinch. However, with so many people in front of him, Lin Hong couldn't very well renege on his debt, so he threw a large bag of spirit stones on the ground with a gloomy face.

Shi Daohan took the bag of spirit stones and immediately noticed something was wrong: "Brother, you only have four hundred and fifty spirit stones here. You're still short fifty."

Lin Hong's face was extremely ugly. He had only brought this much with him, and now he was completely broke.

"Never mind, I won't ask you for those fifty spirit stones. Let's just consider it making friends." Shi Daohan waved his hand.

Lin Hong's face turned ashen. He flicked his sleeves and turned to borrow spirit stones, determined to win back what he had lost.

"Haha, it seems I'm doing really well today." Shi Daohan couldn't stop smiling.

"Young man, how about we make a bet?"

Upon seeing Lin Hong temporarily withdraw, many people immediately voiced their desire to make a bet with Shi Daohan.

In their eyes, Shi Daohan was an complete novice who knew nothing and was just lucky, a lucky break.

"I advise you to bet against her. This kid is incredibly lucky right now, and you'll only lose if you gamble against her," an old man said, pouring cold water on everyone's hopes.

Before long, Lin Hong managed to scrape together over three hundred low-grade spirit stones, intending to continue his gamble with Shi Daohan.

"This time, let's go to the ninth courtyard to pick out raw stones. Are you up for it?"

"Happy to oblige."

Shi Daohan smiled brightly. She possessed the eye of a person with double pupils, which was like having a cheat code compared to others. Who could defeat her?

In the ninth courtyard, there aren't many raw stones, only about seventy or eighty pieces, and they aren't very big either. They were all dug out from the edge of the Immortal Spirit Ancient Domain.

Of course, the so-called edge is at least tens of thousands of miles away. The Immortal Spirit Ancient Domain is a forbidden zone for life, containing great terrors, and no one dares to approach it.

Even the most powerful and influential families only dare to mine spirit stones in areas thousands of miles away.

Shi Daohan walked around the courtyard, cursing the owner of the jade gambling shop dozens of times in her heart. She discovered that at least one-third of the rough stones here were fake ordinary stones.

Genuine raw stones do exist, but they are extremely rare.

The raw stones mined from the Immortal Spirit Ancient Domain all possess a kind of demonic quality, which can be clearly felt.

"Is this strange aura unique to the Immortal Spirit Ancient Domain?" Shi Daohan wondered to himself.

She had only ever felt that indescribable aura outside the Immortal Spirit Ancient Domain.

The most famous and terrifying thing in the desolate state is that ancient forbidden land. No one knows when it started, only that it is very old and ancient, so ancient that its origin cannot be traced.

Lin Hong carefully selected a piece of raw stone the size of a watermelon after a long time.

The master craftsman in charge of cutting stones in the courtyard nodded and said, "This rough stone will definitely yield some products, but it's hard to say how many or what the quality of those products will be."

Lin Hong glanced at Shi Daohan not far away and urged him with some dissatisfaction, "How can you, an outsider who doesn't know anything, understand this? Just pick one randomly, stop dawdling."

"I'm just a complete novice who knows nothing, yet I won over five hundred spirit stones from you," Shi Daohan replied without even looking up.

She was somewhat unsure, as the raw stones mined from outside the Immortal Spirit Ancient Domain all carried a kind of demonic nature, and even with the help of her double pupils, she still wasn't very confident.

"The Immortal Spirit Ancient Domain, what's so strange about that place? Even these stones are tainted." Shi Daohan muttered to himself, even with the help of his double pupil eye, what he saw was still hazy.

She eliminated more than fifty fake ordinary stones and only selected from the remaining twenty or so genuine raw stones excavated from the edge of the Immortal Spirit Ancient Domain.

In the end, Shi Daohan chose a raw stone covered in moss that weighed just over two pounds.

Those watching were speechless, realizing that none of the rough stones she selected looked good.

"Hey young man, you really like to do things the unconventional way. This rough stone has been sitting here for over ten years, and everyone just ignores it. You picked it on your first try," someone sneered.

Shi Daohan scoffed, "Maybe I'll just get lucky again, like a blind cat catching a dead mouse?"

In this courtyard, the master craftsman who specializes in cutting stones began to wield his knife, peeling away layer after layer of stone skin from the raw stone that Lin Hong had chosen, and soon it began to shine.

"What a pure spirit stone! It looks quite heavy!"

As layers of stone were peeled away, one side of a spirit stone was revealed to everyone. It was crystal clear and without a single impurity.

Once the last layer of stone was weakened, this spirit stone weighed over four pounds, but unfortunately, it still contained a lot of impurities and couldn't be considered very pure.

"Although it doesn't quite reach the level of a high-grade spirit stone, this weight is roughly equivalent to more than two hundred low-grade spirit stones," said the master craftsman in charge of cutting the stone.

"Hurry up and cut that young man's rough stone. I want to see if she really can always get lucky by sheer chance," someone urged.

Without delay, the master craftsman immediately took up his knife and began cutting the rough stone that Shi Daohan had chosen.

But in the end, even after the rough stone had been cut from the size of a human head to the size of a fist, it still showed no signs of being ready for sale, clearly making it a worthless stone.

Shi Daohan sighed softly. The demonic aura of the Immortal Spirit Ancient Domain was indeed strange. Even the stones dug out from the edge of the world were still difficult for his double pupils to grasp.

"Hahaha, see? You can't always get lucky and stumble upon success. You've really fallen for it this time, haven't you?" someone said gloatingly.

"The master craftsman in charge of cutting the stone was very dedicated. He kept cutting the raw stone until it was only the size of a lychee before stopping and casually tossing it away."

But when he threw it, it emitted a dazzling light, and immediately a rich spiritual energy emanated from the stone that had been cut down to the size of a lychee.

"Holy crap! They actually shipped it?!" someone exclaimed.

Shi Daohan was also surprised. He held the raw stone in his hand and carefully peeled away the last few layers of stone skin.

"Is that a spirit stone? Or some kind of divine material?"

On Shi Daohan's palm, a point of light was shining brightly, which was very mysterious.

"It's a sealing insect spirit stone!"

"It really is a sealing insect spirit stone! Look! There's a little insect sealed inside that spirit stone!"

Exclamations of surprise rose and fell as everyone saw that inside the spirit stone, which was only the size of a lychee, in Shi Daohan's hand, there was a small worm sealed.

It's impossible to tell what kind of insect it is; it's probably an extinct species.

"It's not some divine material, nor is it a pure, high-grade spirit stone; it wouldn't normally be worth much. But the worm sealed inside it can increase its value hundreds of times!"

"Several hundred times higher? That's an exaggeration!"

"You think that if a piece of amber in the mortal world could fetch an astonishingly high price simply because it contained a mosquito, this spirit stone would definitely also be auctioned off for an astronomical price!"

"Actually, these things don't have much intrinsic value; it's just that their rarity gives them collectible value."

"Before the spirit stone was formed, an insect was accidentally wrapped inside. This is a very rare occurrence, especially since the insect that was sealed inside was an extinct, unknown species. You can imagine how high the research and collection value of this spirit stone is."

The person most shocked at this moment was not Lin Hong, but the master craftsman in charge of cutting the stone.

His face turned green, and he wished he could slap himself a few times. The rough stones here had all been carefully selected by these experienced craftsmen, but they still missed the most valuable one, letting a complete novice who knew nothing about the industry get a great deal.

"I've never seen this kind of insect before. It's probably a species that's already extinct. It has high research and collection value. If it were put up for auction, it would definitely attract huge bids from those big shots."

"If this sealed worm can be used in medicine, its value would increase several times over." (End of Chapter)
