Although Shi Lei has an appraisal card to use, he can use the appraisal card to measure the true value of these rough stones, and then buy them all, so that he can play a role in making money. Pen & Fun & Pavilion www.biquge.info

However, after all, the identification card is a consumable card, and it is used less than once, and Shi Lei believes that he will encounter many situations like this in the future. Even though he had accumulated seven or eight chances to use the card now, he still felt that it was not enough.

It's easy to say that the black card gives the task, anyway, every time it gets off the task, it needs to increase the opportunity to use the identification card three times, but now, Wei Bodhi has become the assistant of the leader of the pupil of the night, Bebera, Shi Lei is likely to be asked to help the pupil of the night to identify various things, if Shi Lei does not have the opportunity to use the identification card at that time, it will make the situation very embarrassing.

Therefore, what Shi Lei needs is his own growth, and it is not a matter to rely entirely on this kind of consumable card.

Shi Lei also gradually began to understand what it meant for Heika to give him the prestige system.

Those various learning cards that he originally didn't look down on may be the ultimate goal of the black card.

After all, Shi Lei's current brain domain development is much more than that of humans on this earth. It may not be comparable to the human beings in the universe where the black card used to be, but it is enough for him to bear and accommodate these various cards that far exceed the technology of the earth.

To put it bluntly, Heika is trying to make Shi Lei as close as possible to the civilization of the universe where it used to be.

After dark, Shi Lei and Qu Xingye returned to the hotel, and after dinner, they went back to their rooms.

After Shi Lei returned to the house, he called up the prestige system.

He saw that his reputation had increased a bit.

Not much, but there are more than a thousand points, and with the remaining reputation from the past, his reputation value has reached more than three thousand three hundred points.

Consuming two prestige points, Shi Lei inquired about the composition of more than 1,000 points.

Basically, there are some scattered prestige values, and the larger ones come from Li Qian Haocheng, Crawford, Jenny and Duke Scola, each of whom has contributed more than 100 to dozens of points, among which Li Qian Haocheng's contribution to the prestige value is the highest.

Philip, Jenny's cousin Philip, who was deeply humiliated by Li Qian Haocheng, also contributed more than 20 prestige points.

What surprised Shi Lei a little was Qu Xingye and Gonda, the behind-the-scenes boss of this trade fair, both of whom also contributed more than ten points of prestige.

The whole combination is almost 700, and after doubling, it reaches more than 1,400.

When closing the reputation value detail query, Shi Lei saw Xu Zhida's name, Xu Zhida actually contributed more than 50 reputation points, in this reputation contribution list, second only to Li Qian Haocheng, Crawford and Jenny, higher than Duke Scola.

Shi Lei frowned, shook his head and said, "It seems that the big mamba still has some resentment this time, is he so unwilling to be transferred to the UK?"

didn't pay much attention to it, Shi Lei returned to the main page.

More than 3,300 prestige points, if you want to get a certain skill or knowledge full level, that is, a card for elementary, middle, and high schools, it happens to be three thousand three, which is really a bit of a trick.

Shi Lei entered the exchange interface, searched carefully, and sure enough, he found the card of primary jade mastery, and after entering the C-level exchange, he found the corresponding jade mastery from the exchange of 1,000 reputation points and the exchange of 1,500 reputation points.

However, what does it mean to be proficient in jade? Shi Lei is really a little unsure.

Of course, jadeite is jade, and it belongs to jadeite, but Shi Lei always feels that this division is a bit unusual.

But where is the problem, Shi Lei can't say.

He didn't rush to redeem these, but continued to look for the parts related to jade characters in the study cards.

Soon after, he saw gem mastery again.

Shi Lei's brows furrowed even tighter, gem mastery, jade should also belong to the gem category.

He didn't dare to slack off, and immediately opened the browser of his mobile phone and began to look up the concept of gemstones.

After a check, Shi Lei suddenly realized.

It turns out that gemstones are divided into narrow and broad senses.

Broadly speaking, gemstones refer to those that have been polished and polished to meet the requirements of jewelry, including diamonds, various types of jade, and even soft organic materials such as amber.

However, gemstones in the narrow sense only refer to natural mineral crystals that can be used for jewelry, including single and double crystals.

Jadeite, on the other hand, is a fibrous aggregate and does not fall into the category of gemstones in a narrow definition.

Even jade is divided into nephrite and jadeite, and jadeite, which is more internationally recognized, only includes jadeite, and does not agree with nephrite represented by Hetian jade.

This is embarrassing, this definition is a little unclear!

The jade mastery that Shi Lei just inquired about is obviously not covered by gemstones.

But it's okay, jadeite is jadeite, and it will be counted in jade anyway.

After such a thing, Shi Lei became more cautious, and he continued to look for the study cards, but as a result, he found a card that made him gasp even more.

Jade proficient!

Isn't there already a jade master? Why is there another jade master?

Shi Lei's brows furrowed deeply.

After searching on the Internet, the definition of jade seen by Shi Lei is made of natural jade. And he couldn't find the exact definition of jade.

Shi Lei's mind echoed the words jade and jade, and he generated a definition of jade on his own.

Since jade and jade are distinguished, and the definition of jade is a processed object, then jade refers to all kinds of jade before it is not processed.

This means that what Shi Lei needs now is to be proficient in jade, because what he is facing is jadeite rough, which is of course not a processed artifact, but only jade.

Exhaling lightly, Shi Lei said in his heart, fortunately, he was not proficient in the exchange of jade in a hurry just now, otherwise, this exchange would be in vain.

After hesitating for a moment, Shi Lei still decided to use the reputation points, and he exchanged them for elementary jade mastery, medium jade mastery, and advanced jade mastery.

After using them separately, Shi Lei recalled the jadeite rough stones he saw during the day, and he already had an intuitive and clear understanding of these things in his mind, and even he could already feel which rough stones could produce valuable jadeite.

But he also understands that he is now just equivalent to a person who knows a lot about the rough stones, maybe on this earth, there is no one who studies all kinds of jade rough stones who can know more about these than him, but this is not certain, and there will definitely be times when he will lose his eyes.

However, with these three learning cards as the foundation, Shi Lei wants to use more than 4 million independent funds in his hand to buy a part of the original stone, and ensure that its appreciation should be no problem.

If you want to judge these rough stones more accurately, I am afraid you still have to rely on identification cards.

And to verify his knowledge of the roughs, this time he may still have to use an identification card.

But no matter what, Shi Lei has enough confidence about the selection of rough stones tomorrow, and he decided to rely on his current understanding of jade materials to select first, and then use the identification card.

What's more, Shi Lei still has a ENT card to use, and the original mastery of jade requires the cooperation of eyesight, ear power and touch, etc., Shi Lei believes that he will be able to choose the original stone he needs.
