Ye Han only felt like a turtle in the countryside, and he had never heard of these terms.

The boss didn't delay too much and walked directly to the counter.

Pick up an object the size of a brush and sweep it over the hedron several times.

After more than ten seconds, the boss put down the device in his hand.

Looking at this low-grade spar, it was as if he had seen some terrible treasure in his eyes.

The boss looked at Ye Han, and then at the spar: "Little brother, where did you get this low-grade spar from, it's really a good thing." ”

Ye Han did not answer, and there was no need to answer.

Seeing the appearance of the boss, Wei Ziyan couldn't help but ask, "Boss, how high is the purity of this spar?" ”

The boss smiled, and his finger clicked a few times on the instrument that had just been scanned, and a digital head was printed in front of everyone.

“94.3%？ It's so high! ”

Even though Wei Ziyan and the driver were prepared in advance, they were still taken aback by this number.

Ye Han was a little embarrassed and asked in a low voice, "Ziyan, what does this mean?" ”

Wei Ziyan explained softly: "To put it simply, the higher the number, the higher the purity. ”

The boss didn't laugh at Ye Han, but was happy to explain Ye Han in detail.

"Regardless of the grade of spars, purity higher than 50% is general quality, higher than 60% and lower than 80% is called excellent quality, and higher than 80% is collectively called fine quality."

Explaining this, Ye Han was a little puzzled: "Then why do you say that this piece is a perfect quality?" ”

The boss touched the spar in his hand, as if he was touching his lover, which made Ye Han shudder a little.

He said with a smile: "Because there is very little circulation in the market for spars with higher than 90% quality, the cost is high, the difficulty is great, and the demand is very small, so the so-called high-quality products are all of less than 90% purity." ”

"More than 90% of the average person won't buy it, so the outside doesn't care about it at all."

"However, we in the industry call more than 90% of fine spars as perfect quality, which can be sold to those who need them through special channels."

Ye Han smacked his tongue, he didn't expect the water in the spar industry to be so deep and so exquisite.

Soon the boss said to himself: "It's really strange, the raw materials of low-grade spars are often of very low quality, and they should have been broken long ago when they are purified to this strength......"

Ye Han's heart tightened, he was worthy of eating this bowl of rice, and he could see the problem at a glance.

After looking at it several times, the boss put it on the countertop.

"Little brother, the quality of your spar is indeed very high, how about I buy it at a price of 20,000 catties?"

As he spoke, the boss raised two fingers and kept observing the change in Ye Han's expression.

"Twenty thousand?"

Wei Ziyan frowned, she was also knowledgeable, how could she be coaxed so easily.

She said categorically: "This price is low." ”

"Is this still low?"

Ye Han was almost carried away by this sudden happiness.

You must know that the general quality of the lower grade spar is only about 10,000 pounds, and now this piece has doubled!

The driver behind him also smiled and echoed: "You can deceive laymen at this price, but you can't deceive our young lady." ”

Only then did the boss see that Wei Ziyan in front of him was definitely not an ordinary person.

However, when he was old, he immediately sold miserably: "This young lady, although this spar is of high purity, but after all, it is only more than a catty, and the amount is too small." ”

"We also have to go through special channels when we sell to others, and the cost itself is not low, and the price is already very good."

But before Wei Ziyan could speak, a voice as warm as the wind came from behind Ye Han.

"Boss Wang, your price is really unkind."

Hearing this voice, the boss immediately straightened up.

hurriedly stepped forward: "Ouch, it turned out to be Miss Shen, why did you come here!" ”

Ye Han turned his head to see that the person who came was a woman in her early 20s with a noble temperament.

He has long hair and dignified facial features that are not heavy.

A black coat is even more atmospheric, and people can't help but look sideways.

In addition to this woman, there are two men in suits behind her.

Judging from the attitude of the boss and the appearance of this woman, she is definitely not an ordinary person.

Miss Shen didn't respond to Boss Wang, but walked straight to the counter and looked at the spar.

Boss Wang next to him lowered his head, and he didn't dare to gasp.

Immediately, Miss Shen turned her head to look at Ye Han, and said with a shallow smile: "Little brother, this spar is yours?" ”

Ye Han didn't have stage fright, and nodded very calmly: "That's right." ”

"Less than a pound and a half."

"It's more than three pounds."

"That's all?"

The two asked and answered, and Ye Han hesitated for a moment.

As long as the raw materials are sufficient, then of course you can't only have so much.

But in the face of this unknown woman, she must not answer easily.

Seeing Ye Han's hesitation, Miss Shen also understood something.

So she accepted it when she saw it: "Whether you still have it or not, I will accept this spar at a price of 30,000 catties, and if you still have this quality spar in the future, I will accept it at this price, no matter how much it is." ”

Ye Han took a deep breath excitedly, he had met a nobleman!

Boss Wang next to him couldn't help but speak: "Miss Shen, isn't this price a bit high?" ”

"Not high." Miss Shen gently tapped this spar, "Although the demand for this purity spar is very small, not to mention how high the cost and energy of purification is, it is worth the price itself." ”

Ye Han was moved to almost tears, as if Maxima had met Bole.

This Miss Shen is really generous.

After finishing speaking, Miss Shen waved her hand slightly, and a string of figures transformed by light and shadow immediately appeared in front of Ye Han.

"My name is Shen Yueming, this is my contact information, if there is still a spar of this quality, you can contact me directly."

Then Shen Yueming handed over a card to Ye Han and turned around and left with the spar.

Looking at Shen Yueming who was leaving, Wei Ziyan was surprised: "It turned out to be a smart brain!" ”

Ye Han was also a little distracted: "Is this the wisdom brain, it's really powerful......"

The so-called intelligent brain is an artificial intelligence created by combining the technology before the first year of the new calendar and the mysterious technology that appeared later.

The definition of the brain is actually very vague.

Because the bracelet in Ye Han's hand can also be regarded as a smart brain, but this kind of thing is one for everyone.

And the algorithm is extremely weak, with very few functions, and it is not much different from the artificial intelligence before the first year of the new calendar.

Like Shen Yueming's intelligent brain, it can be integrated into the human body without any effect.

What's more, the algorithm of this higher intelligent brain is extremely strong, and even has wisdom far beyond ordinary people.

Only such an existence will be called by the word "smart brain".

Its complete functionality is unimaginable, and Shen Yueming's hand can see one or two just now.

Use light to project numbers, and it's sure it won't go away for a few minutes.

That's where the power of the brain lies!
