Under the different gazes of everyone at the scene, Su Huai took a slight breath and carefully observed the golden seal with a magnifying glass.

The flying bear button is very exquisitely made, the bear body is arched into a bridge, the limbs climb out of the corner of the Indian side, and the two ribs each stretch out a wing, close to the body, which can not only reflect the state of soaring, but also will not affect the use of the seal.

Ma Long said lightly beside him:

"This is one of the best preserved Chinese cultural relics in our group, but it is very old, and I don't know how to tell the year......

These words were obviously deliberately putting pressure on Su Huai, and at the same time deceiving Su Huai, if Ma Long didn't know the origin of this golden seal, he would not have been able to take it to test Su Huai, but Su Huai turned his head and said strangely:

"You don't know the age, wouldn't it be good to use the instrument to detect it directly?"

Ma Long smiled disdainfully: "Mr. Su is a layman, now the commonly used direct-reading spectrometer, the effect is to detect the chemical composition of cultural relics, but the age can not be determined, to test the age of cultural relics, rely on vision, experience, if there is an instrument that can directly tell you the results, then what do you want our group to raise hundreds of experts?"

Sotheby's is the world's most authoritative antique appraisal agency, relying on not instruments, but rich experience and accumulation of cultural relics identification, after the catastrophe, the institutions that handle cultural relics in various countries, only they have absolute authority in the industry.

But hearing this, Su Huai was a little surprised in his heart, and said in surprise: "Isn't it possible to check the year of the item by using the carbon fourteen dating method?"

Carbon-14 is a radioactive isotope of carbon, which can be used to calculate the approximate age of a sample based on the degree of decay of carbon-14.

Originally invented in 1960 by a professor at Berkeley University to identify fossils, this method has since become a great way to identify antiques.

It is also the only way to date a sample by scientific instruments.

The only drawback is that the cost of testing once is also very high, and ordinary things are not worth using at all, so they have always been used by various state agencies, and ordinary cultural relics will not be tested at all.

It's normal that there are no ordinary appraisal agencies, but since Sotheby's has the world's largest antique auction house, they can't have this instrument, right?

Ma Long was a little surprised when he heard this, but the female expert next to him sneered:

Sotheby's has been testing cultural relics for so many years, and has never heard of the carbon 14 dating method...... Could it be that you have any new research results in the Chinese academic circles? ”

"Yes...... Is that so?"

Su Huai opened his mouth slightly, and the people of the Huaxia Federation of Literary and Art Circles all looked at each other in their hearts, secretly screaming that it was not good.

I'm afraid it's not good this time...... Although Su Huai is unparalleled in literature, he doesn't seem to understand much about these science and technology in the archaeological world, so he just said two words and fell in front of Ma Long, what can I do.

Kirk, Russell and others all showed sarcastic smiles, this Great Sage of Su can be regarded as a heel.

Everyone looked at Su Huai and frowned slightly, thinking that he was a little flustered and at a loss, but they didn't know that Su Huai was sighing in his heart at the moment:

This time and space is still very different from his original world, because of the existence of the United Nations, there is no process of military hegemony between the United States and the Soviet Union, and many of the original scientific and technological promotions are in the military competition between the two superpowers of the United States and the Soviet Union, with the strength of the whole country, vigorously developing some military-related high-tech industries.

For example, mobile phone communications, aerospace technology, etc., are all born from the accumulation of technology during the period of hegemony between the United States and the Soviet Union.

However, this time and space lacked the Cold War hegemony of the United States and the Soviet Union, so the Internet was more popular than mobile phones, and aerospace was still in a very backward stage, and manned technology was not mature.

It seems that no one has studied this carbon 14 dating method in this time and space, which is a huge loss for the archaeological community, but for him Su Huai, it is a major good news.

When Su Huai thought of this, he couldn't help but get excited, because the carbon 14 dating method is the only way to detect cultural relics that can determine the year, and the rest can only rely on the vision and knowledge of cultural relics experts.

And in this regard, in this time and space where cultural relics have been lost after the catastrophe, no one can compare to him!

"Mr. Su, have you finished reading it?" The female expert next to Old Ma Long, seeing his strange expression, was a little afraid that he would be angry for a while and break the golden seal.

Ma Long smiled, waved his hand and said, "Let Mr. Su take a good look, so as not to wait and say that we didn't give him enough time." Saying that, Malone also smiled:

"Mr. Su, I think so, you take this gold seal back, study it for three days, and after three days, you tell me the results, anyway, our group still has tens of thousands of pieces of this kind of thing. ”

Ma Long pretended to be generous, but he actually humiliated Su Huai and looked at the representatives of the Federation of Literary and Art Circles of other countries, and also created pressure on Chairman Fan's follow-up campaign.

Everyone in the Huaxia Federation of Literary and Art Circles is indignant, but there is no way to take the other party's cynicism, although they are numerous, but where does anyone understand this antique appraisal.

Although there are many cultural relics excavated in the Ming Tomb, the number of cultural relics is still too far away to summarize and identify the laws of cultural relics.

But at this moment, Su Huai unexpectedly put down the golden seal and said lightly: "It's already good." ”

Okay? Does it mean that it has been identified, or has it been abandoned? The representatives of the Federation of Literary and Art Circles of various countries were very curious about what Su Huai meant.

"Mr. Su, it really deserves its name, and he can see the way out so quickly~~" Malone laughed, "Papapa" clapped his hands vigorously, but anyone could hear the sarcasm in his tone:

"Then please tell Mr. Su the origin of this golden seal. ”

He calculated that Su Huai didn't have the ability, so he deliberately said this, but he didn't expect Su Huai to say:

"Although the specific year of this seal of the Han Dynasty in China cannot be determined, it should be one of the official seals after Emperor Ping of the Western Han Dynasty. ”

Ma Long's face was fixed and silent, and the female expert next to him asked, "How did Mr. Su conclude it?"

As soon as everyone heard it, they knew that Su Huai was right, Su Huai not only determined the dynasty, but also which period, which was very surprising.

Su Huai said: "It's very simple, this seal is engraved with 'Xudong Wende Men's Seal'; a few words, of which 'Xudong Wende Men's Family' is Zhu Wen, and the word 'Seal' is Baiwen...... It is a fallacious seal carving, which is a commonly used fallacious script font made and printed in the Han and Wei dynasties......"

Everyone else listened with ignorant faces, but Ma Long and the others all looked solemn, the so-called 'Zhu Wen' is the yang engraving with the convex inscription, and the yin engraving is Baiwen, Su Huai can say these two words, which proves that he is not a layman......
