"The material used in this Longquan sword is special steel, which is indeed more corrosion-resistant, but presumably everyone will not know that in this world, no matter what high-quality steel is used, it will not be 100% corrosion-resistant, including this Longquan sword, it also has its own weaknesses."

"In its steel materials, in addition to some synthetic metals, there is a little carbon, when the carbon and iron in the metal are stored in the environment for a long time, or close to the water source, then it will produce oxygen absorption corrosion effect, which is affected by moisture, a year or two, or even ten or eight years may not be able to see the obvious effect, but if more than fifty years, this slight impact will become a big impact, the reason why this Longquan sword will corrode, is affected by this moisture."

"If my guess is right, this uncle must not know these things, so improper storage will cause corrosion on the surface, uncle, am I right?"

After Chen Feng explained in detail to everyone, he looked at the old man.

"Yes, yes, that's right, that's it...... That's it, I'm ...... I do usually place it in the back compartment of a sink, so good...... I haven't touched it for decades, and it's just ...... It's just that I'm afraid that people will steal it secretly...... Steal it. ”

The old man's expression suddenly became excited, nodded again and again, and said to Chen Feng in a stumbling manner.

In an instant, the audience suddenly realized.

It turns out that this sword has been subjected to moisture for decades, and it is not difficult to understand the corrosion on the surface.

Several other treasure connoisseurs frowned, they had really lived for a long time, and it was the first time they had seen such a treasure collector who was extremely irresponsible for treasures.

The storage environment of this weapon is almost unknown to everyone.

Isn't most of the weapons stored away from dampness and in a dry and cool place as much as possible?

How could this old man not know?

"Hmph, it's complete nonsense, as a treasure hunter, how can you not know to wrap the sword well and put it in a cool and dry place? The excuses you said are clearly deceiving children, and if you want me to see it, it must be that you have reached a consensus with this old man before you came to power, and you want to deliberately say that this fake sword is a real sword. ”

Wu Hanhu was not convinced, and glared at Chen Feng fiercely.

Several other treasure connoisseurs shook their heads after all, after all, their identification results were the same as Wu Hanhu's, one may be wrong, it is impossible for all of them to be wrong, right?

If so many treasure connoisseurs are no match for a young boy, then where will their faces be placed in the future?

Suddenly, several treasure connoisseurs shouted one after another, all of them resisting Chen Feng's explanation.

However.

Chen Feng disagreed, he had more convincing evidence to prove his opinion.

After they were noisy for a while, Chen Feng sneered and continued: "Wu Hanhu, you yourself are not in a good appraisal, and you have brought everyone to slander me, I see that you and this sword are really similar, the sword is an absolute real sword, and you are not inferior to this sword at all." ”

"Huh? What do you say, stinky boy? Are you scolding Lao Tzu? ”

Wu Hanhu's face suddenly turned cold, he reacted, Chen Feng seemed to be saying that he was cheaper than a sword, and suddenly couldn't help but clench his fists and shouted fiercely.

"Hehe, when did I scold you? Don't get me wrong. ”

Chen Feng chuckled lightly and responded with a response, which caused the people at the scene to be happy.

Wu Hanhu's face was flushed.

After a few seconds, Chen Feng continued to explain: "Listen to me, I really don't know this uncle, this is also the first time we have met, I help him identify the authenticity of the treasure, that is to fulfill my duty as a treasure connoisseur." ”

"The reason why I can judge the rust on this sword is from the clothes of this uncle, you look at this uncle, his clothes are simple, and his shoes are still muddy, at first glance he is an old farmer, but his skin is whiter, his hands are like being blistered for a long time, and his body is very damp, it can be seen that he has been dealing with aquatic crops for a long time, and the place where he lives must be very close to the place where he works, so in his environment, it is even more difficult to find a cool and dry place to hide treasures. And this old man probably really doesn't understand how to store this sword, so it will cause the sword to rust, and the appearance of this rust is just a natural phenomenon, and it does not prove that it is a fake sword. ”

Chen Feng's explanation directly denied the appraisal results of the treasure connoisseurs at the scene, and the audience at the scene also agreed.

The old man's face was overjoyed, his heart was very excited, and he expressed his gratitude to Chen Feng for his correct explanation.

And the reason why Chen Feng was able to see these was because when he was on Earth, his parents were all farmers, so he knew farmers very well.

At this uncle's age, it is very likely that he has never even gone to school, and he doesn't know a few words, how can he know this kind of knowledge of the environment in which the sword is stored?

As long as this sword is not lost, it has already made a great contribution to him.

As for these well-known treasure connoisseurs on the stage, they have been carrying out treasure appraisal work under excellent conditions for a long time, and they have no understanding of the life and suffering of the common people, and can only analyze the problem from the perspective of treasure connoisseurs and treasure collectors, and it is naturally difficult to distinguish the truth from the false.

After listening to Chen Feng's explanation, Zhou Yuhua suddenly realized.

It was this in his mind that he had just wondered, this sword did not look like a fake sword, but the rust could not be explained.

Even though he also thought that this old man might have corroded this sword to a certain extent because of the humid environment he was in, he still couldn't be sure of his conjecture, because he couldn't see through the specific alloy composition of this sword's steel at a glance like Chen Feng.

Moreover, he has lived in the city for a long time, like the common disease of several other treasure connoisseurs, how can he know that in the eyes of the peasants, the amount of insight and knowledge is far inferior to that of a city person?

Therefore, under heavy suspicion, he did not dare to speak presumptuously, otherwise he would only make himself unable to step down.

"Hmph, Chen Feng, you keep saying that this sword is real, then you can also show us evidence, even if you deny our identification results and say that this rust has nothing to do with its authenticity, then how can you be sure that this sword is real?"

Wu Hanhu refused to let go of Chen Feng and questioned again.

How can this point be difficult for Chen Feng?

Chen Feng didn't listen to the sound of the sword in vain.

And such a good sword, such a magical phenomenon, he will not have it alone.

Grinning slightly, Chen Feng continued to explain: "Of course I have more sufficient evidence to prove! ”
