"I've heard of the anti-corrosion technology of the ancient sword, it's indeed a pity, this thing is not the sword of King Qin, nor is it the sword of King Yue, but it may not be worse than those two swords. Zhang Tianyuan said with a smile.

"Boss Xiao Zhang, what do you mean by this? As far as I know, there are very few known swords that can not decay for thousands of years in China, and the Yue Wang Sword and the Qin King Sword can be regarded as a top performer, do you think that this thing that has rusted into iron is actually at the same level as those swords?"

"Why not?" Zhang Tianyuan smiled.

"Wait a minute, what are you two talking about, what is going on with the Yue Wang Sword and the Qin King Sword?" After all, Ruijin Richard has been away from China for a long time, so he doesn't know much about this side of the matter, and I am afraid that I have never heard of the Qin King Sword and the Yue Wang Sword, and I can't help but ask when I hear Zhang Tianyuan and Lao Yu talk about it.

"The sword of King Qin is a name added by later generations, in fact, it is a bronze sword found in the Qin Warriors!" Zhang Tianyuan explained with a smile: "The bronze sword unearthed in the Terracotta Warriors and Horses has not broken for 2,000 years, and the bronze sword unearthed from the No. 2 pit is 86 cm long, and there are 8 edges on the sword body, which is extremely symmetrical and balanced. The discovery of the sword of King Qin took more than 2,000 years and was unearthed from the ground, but it was free of corrosion and rust, and it was as clean as new. ”

"Is it really that amazing?" asked Ruijin Richard in surprise, "This kind of embalming technology existed in ancient times?"

Later, modern scientific methods were used to detect and analyze, and the surface of these bronze swords was coated with an oxide film about 10 microns thick, which contained 2% chromium. The discovery of King Qin's sword immediately shook the world. Because this kind of salt oxidation treatment is an advanced technology that has only been mastered in modern times. ”

"My God, I seem to have heard that this technique was German in 1937. The United States only invented and applied for patents in 1950, and it was only realized under a relatively complex set of equipment and processes. This Qin man actually has this kind of technology!" Ruijin Richard's mouth opened wide in surprise.

"yes. The high level of casting of the Qin people is really incredible. In fact, there is another interesting thing, it is said that the discovery of the sword of King Qin, what is particularly commendable is that the toughness of these bronze swords is extremely amazing. There was a sword that was bent by a 150-kilogram terracotta figurine, with a bend of more than 45 degrees. The moment the terracotta figurines were removed, a miracle happened, and the bronze sword bounced straight up. Natural restoration. This exquisite sword-forging skill is jaw-dropping, but I don't know why. Zhang Tianyuan sighed with emotion, he often slipped to the Qin Warriors to play when he was a child, and he had seen these swords, but at that time he just felt magical, and now with the increase of knowledge reserves, he feels that those things are even more incredible.

"Well, the situation with that Yue Wang Sword is actually similar. The world-famous Goujian sword of King Yue was unearthed in December 1965 in a tomb of a Chu nobleman in Wangshan, Jiangling, and is now Wangshan Village, Chuandian Town, Jingzhou District, Jingzhou City. The sword is 55.6 centimeters long, although it has been buried deep underground for more than 2,300 years. It's still as clean as new, cold and sharp. It is said that this sword also uses a special anti-corrosion technology. It's not the same as the sword of King Qin, but it's so well preserved. Even modern technology can't do it, so it's a mystery. The old shopkeeper also said to Ruijin Richard.

"So, those famous swords in ancient times probably have similar embalming techniques?" asked Ruijin Richard.

"That's probably it, if you can become a famous sword, if you don't have this technology, you probably won't be qualified. It's just that many of the legendary famous swords have long been lost, and now they can't be confirmed, of course, maybe today you can see a long-lost famous sword!" Zhang Tianyuan suddenly pulled the topic back to the sword in his hand.

"I said Boss Zhang, you don't mean this rusty sword, do you?"

"Why not?" Zhang Tianyuan smiled and said to the shopkeeper of Lao Yu: "Please find a file, and sandpaper, I will show you, what is this so-called rusty iron piece, in fact, I also want to know its true face of Lushan!"

Although the old shopkeeper was strange, he still went to help Zhang Tianyuan get the things he needed, and then put them aside, files, sandpaper, and some gauze and other things.

"Teacher Zhang, I just said it for a long time, you don't seem to have listened, this sword can't be polished by yourself casually, it's better to be a professional grinder. Ruijin Richard saw that Zhang Tianyuan wanted to use these things, and he didn't understand what Zhang Tianyuan wanted to do, so he persuaded him a little nervously.

Zhang Tianyuan scraped off the patina on this sword with a file, and said: "Director Richard, don't worry, the so-called peerless sword, even after endless years, even if it is covered with thick dust, it will definitely bloom with its original light!"

For Zhang Tianyuan's words, Ruijin Richard was a little scoffed, he felt that Zhang Tianyuan was paranoid, although his identification skills are not very good, but the maintenance technology is very proficient, like this kind of random rust removal, he is the first time to encounter it, and he feels that this is nonsense.

It's true that you can regain brilliance after being dusty, but it's not dusty, it's already rusty, it's almost rusty, that is to say, even if you scrape off the rust, this sword is not the original sword, how to talk about the famous sword?

However, Ruijin Richard didn't say anything, he wanted to see what tricks Zhang Tianyuan was going to play next, he was looking forward to it, on the previous road, he had already checked some of Zhang Tianyuan's information through his mobile phone, and then he learned that Zhang Tianyuan was the first-class treasure master in China, and such a young treasure master also surprised him, so although he was suspicious now, he still had a little bit of expectation, maybe he could really see immortal things.

When Zhang Tianyuan was removing rust, he kept using the word appreciation trick, and he didn't want his recklessness to really destroy the sword, because he knew that this sword was actually a sword in the sword, and the inside of this sword was hollow. And inside the hollow, there should be something else. As for what it is, he is almost certain that it should also be a sword. However, it should be smaller than the sword outside, and the outside sword is also an ancient sword, but it is only used as a cover.

"Well, old shopkeeper, please help me get a hammer. After Zhang Tianyuan removed the rust, he saw that there were many cracks on this bronze sword, which should belong to an ordinary ancient sword, although it was a pity if it was broken, but it would not stand if it was not broken. If you can take the contents out, it doesn't matter if you destroy it.

"What do you want a hammer for, aren't you afraid of destroying this sword?" Ruijin Richard suddenly became nervous, after all, he is a sword lover, and he has always disagreed with the practice of destroying the sword, but now that Zhang Tianyuan is going to do this, it is clear that he wants to destroy this sword, can he not be in a hurry?

"I'm going to destroy it, because I don't want to destroy it. You won't be able to see a truly peerless sword!"

"Boss Zhang, do you mean a sword in a sword?" Old Yu understood what Zhang Tianyuan meant first, but he was a little worried: "I've only heard of a picture in a picture, a word in a word, but I have never heard of this sword in a sword." How did you know there must be something in there?"

"The weight is not right, the weight that a sword should have is completely different from this sword. So I doubt there should be something in it, as for whether it's a sword or not. I'm only five points sure, of course. It may also be the martial arts cheats in Yitian Sword, then you and I have become martial arts masters. Zhang Tianyuan made a joke to ease the tense atmosphere.

"What if it's not a sword?"

"It's okay if it's not, as you can see, this sword has become like this, it has no research value, and it has no collection value, so it's better to give it a good time than to keep it, no matter what is in it, I want to see it, otherwise, I won't be able to sleep at night." ”

"It's crazy. Ruijin Richard shook his head, he always felt that Zhang Tianyuan's approach was too risky.

Zhang Tianyuan smiled and didn't say anything more, but started directly, because he couldn't explain, he couldn't say that he could see through this sword, in that case, it was estimated that he would be more famous than this sword.

However, in order to avoid breaking the sword inside, Zhang Tianyuan's every movement was very careful, and although he could knock the cracked sword open in this way, it would take a long time.

Because the sword was rusty, the sound of the blow was not crisp, but it was really possible to hear some strange echoes from the sound, as if there was space in the sword, resulting in an echo.

"Teacher Zhang, if you don't like to hear something, unless the things in this are ancient famous swords, such as Longquan, Dingguang, Zhanlu, Ganjiang, Mo Ye and the like, otherwise, I'm afraid that the sword in this will also be rusty, and you may be disappointed at that time." Richard was silent for a moment, and then seemed to be a little unable to hold back, and then spoke.

"In fact, it may not necessarily be a famous sword, as long as it is a sword that uses anti-corrosion technology, it should not be easy to rust, you are like those bronze swords in the Qin Warriors, it is not a famous sword, but it is a mass production thing, and there is no rust, so I don't want it, as long as it does not rust, as for whether it is a famous sword, it is a trivial matter. Zhang Tianyuan can think about it, he doesn't expect this sword to be a historical sword, as long as it is an ancient sword that does not rust, it is enough, originally he wanted such a collection, but now he may be able to get his wish.

Ruijin Richard smiled bitterly, and didn't say anything more, anyway, he could see that this Teacher Zhang was iron-hearted, no matter what he said, it was useless, rather than distracting him, it was better to just watch quietly.

In fact, whether this sword is valuable or not, he is not interested at all, all he wants is an ancient sword, which is enough, but the ancient sword should be worth some money, so this is not contradictory.

He believes that the sword in this will definitely not be worse than those Qin King swords, or the grade is higher, in case it is really some ancient famous sword, similar to the Longyuan sword, the fish intestine sword, the Seven Star Sword and the like, it will be even better, after all, people, are always a little greedy, since they want to collect, it must be better to collect.

After beating for more than ten minutes, Zhang Tianyuan finally stopped, and then took a deep breath and said: "The two of you are optimistic, the time to reveal the mystery has come, what will this make, I also want to know, is it Juque Zhanlu? or Seven Star Longyuan......?
