Chuchen said with a smile: "Uncle Wu, I didn't mean not to tell you about this. Coco and I got the cup when we were in England. Later I went back to Beijing. You were still out of town. Besides, I was busy at that time, so I forgot about it. I'll go to the vault and take out the cup in a moment. I'll show you enough! "

Uncle Wu heard that, and he was not really angry with chuchen, so he stopped complaining about chuchen. However, he murmured: "coco is such a girl, I don't know how to call me and say it!"

"I guess she forgot about it, too!" Chu Chen quickly made a comeback.

Seeing Chu Chen's eagerness to defend Wu Ke, Wu Shu laughs and thinks happily that the young couple have a good relationship. It seems that the son-in-law can't run away.

At this time, Hu Yong proposed: "why don't we try to cut iron like mud now?"

Wu Shu shook his head and said, "forget it. Generally speaking, every time a sword is used, it will produce a concussion, which will destroy the stable structure of the object. The harder the object is, the greater the concussion will be."

"Therefore, from the perspective of the protection of cultural relics, if you want to test the sharpness of ancient swords, you can just try it on paper. After all, this fish intestine sword is an artifact of 2500 years ago. In case of any damage caused by cutting hard objects, it's not worth the loss. "

After listening to Uncle Wu's words, they both nodded their heads. However, when people encounter something they are interested in and don't understand it, they always think about it. Chu Chen is no exception. He just saw a small piece of wood beside him, so he quickly went over and took it, and then handed it to Hu Yong and said:

"just try this one!"

Uncle Wu saw that what Chu Chen had brought was only a small stick, so he didn't say anything.

Because of the experience just now, Hu Yong just used a little strength to test it at the beginning, but he only saw that he cut the stick gently, and the stick became two pieces just like the hair just now. This kind of result, let Hu Yong already shocked numb.

In this regard, Uncle Wu can only sigh: "it's really worthy of the ten famous swords. It's really worthy of the name!"

"Yes Chu Chen nodded and agreed: "and I think the pattern on the fish intestine sword should have a work that can't heal the wound, plus its sharpness, so the historical records will say" Wang Liao died. "

Hearing what Chu Chen said, Wu Shu and Hu Yong immediately thought that with the sharpness of the fish intestine sword and the special pattern on it, once it hit people's body, it really made them dare not imagine. They could not help shivering.

Immediately, Uncle Wu said seriously, "Xiao Chen, you'd better put this sword away. You'd better make a scabbard in your spare time."

"Well!"

Chu Chen nodded, but when he thought of the scabbard, he thought of the wrapped fish skin, so he looked at it. At this time, he thought of a key question, why is the surface of the fish skin not damaged at all?

If it's an ordinary sword, it's OK to say, but it's a sharp weapon that blows hair and breaks hair! The first thing Chu Chen thought of was, how could this be possible?

Uncle Wu, they followed Chu Chen's eyes and saw the fish skin. After a while, they all thought of Chu Chen's doubts and disbelief and couldn't help looking at each other.

Chu Chen quickly said: "Hu Yong, you try to row with the fish intestine sword. Just remember to row on the corner. First time, use less force."

"All right!"

Hu Yong nodded, and immediately went to the table. He only used the strength of the stick to cut off just now, and then drew a sword at a corner. The result made the three people quite shocked and unbelievable. There was no trace on the fish skin!

Chu Chen had some guesses before, so he directly asked Hu Yong to use a little more force, two points, three points until eight points. The fish gut sword made a deep mark on the fish skin, but it was not the most shocking. Then Chu Chen went up and stroked it gently, and the mark was gone!

"How could that be?" Seeing this result, Wu Shudu was already silly. With the sharpness of the fish gut sword, even if it was an elephant in front of him, he must have cut the skin of it with 80% force. But the skin in front of him looked like a fish skin. How could it be cut down without any reaction?

"Isn't this skin a fish skin?" Hu Yong murmured to himself in surprise.

Chu Chen thought about it and said, "it's possible, but it's also possible that it's the skin of an extinct fish. You know, the iron sword with this fish gut sword was from the Han Dynasty. At that time, even the things in the three sea classics could be found. It's not impossible to catch this kind of fish with very tough skin."

Hearing what Chu Chen said, Uncle Wu thought it was possible.

It is said that during the reign of Emperor Wu of the Western Han Dynasty, someone contributed a strange bird to the emperor and fed it all kinds of food, but it refused to eat it. When Dongfang Shuo saw the bird, he gave its name and said what it should eat. An experiment, as Dongfang Shuo said. The emperor asked Dongfang Shuo how he knew. He said that there were records in the book of mountains and seas, and he would know after reading them.Although this is only a legend, its authenticity also needs to be verified, but after all, sanhaijing is the accumulation of what the ancient generation of witches saw and heard through word of mouth. Although there is exaggeration in it, it's not necessary to say that the exotic animals do not exist, but some of them have not yet been proved.

Hu Yong was very confused and said: "that's not right. If there was such a fish, how could people catch it at that time? How can you cut its skin so neatly? "

Chuchen said with a smile: "the wisdom of our ancients is very powerful. If you think about it, the great wall can be built, let alone a fish? What's more, it's true that every iron rod can be ground into a needle, so it's hard for them to split the skin. "

"Yes Uncle Wu said with emotion: "it's just that our country has always been separated and combined. In addition, there are many requirements for ancient inheritance, so many technologies have not been inherited. It's a pity to think about it."

Hearing this, Chu Chen sighed, and then said, "OK, let's put this sword away first. After I show it to the master tomorrow, I'm going to have people study this sword, hoping to find out why it's so sharp at that time."

Although Chu Chen knew that there was little hope for the success of his research, if he did not study it, there would be no hope at all.

Uncle Wu had no opinion about it, but he immediately remembered that Chu Chen had another good thing, so he said in a hurry, "let's go and have a look at the self warming cup."

"Uncle Wu, can you wait for a while?" Chu Chen scratched his head.

"What else?" Uncle Wu asked with some doubts.

"Look at this picture first."

Chuchen, with a smile, took out the beautiful picture of Lin ting and unfolded it.

Uncle Wu thought that Chu Chen had bought another good painting, so he rushed up to have a look at it. However, he was disappointed that it was a Qing imitation.

"I said Xiaochen, it's an imitation of Qing Dynasty. What's good to see?" Uncle Wu said some speechless.

"Take a closer look at the mounting of this painting." Chuchen said with a smile.

"Well?"

When he heard Chu Chen say that, Uncle Wu felt a little curious. He looked back at the mounting of this work, and his face immediately looked surprised. He was afraid that he might be wrong. He looked at it carefully and found that it was really a master level mounting technique.

You know, this is the original old mounting, and it's also a master level craft. At that time, the price of such an imitation was not expensive, and which mounting master had nothing to do when he was full. As a painting, it's not a very good imitation mounting?

Of course, everything is not absolute. Maybe this painting was painted by someone with a lot of money, or the master can't help him mount it. However, this possibility is too small, and scholars generally have a good face, so the probability of doing this kind of thing is not high.

Besides, if it is really painted by such powerful people, he may not leave his own taboo.

"Strange, this painting is really strange!"

Uncle Wu murmured to himself, and then he suddenly thought of a possibility. He quickly twisted the paper with his hand, and carefully observed it with a magnifying glass. Then he frowned and said:

"it seems that there is no painting hidden below!"

"Yes, not really!" Chu Chen nodded.

Uncle Wu shook his head. He couldn't see what was wrong with the painting. "Well, Xiao Chen, don't play tricks any more. Come on, tell us what you found."

"Look at this gap." Chu Chen said with a smile, pointing to the scroll at one end.

"Crack?"

Wu Shu and Hu Yong quickly put their heads together. According to Chu Chen's instructions, they finally found a small gap in the shaft head.

This gap is so small that it looks thinner than the hair. If it wasn't for Chu Chen's instruction and the magnifying glass, they would not have found it. This surprised both of them.

"Xiao Chen, how can you find this gap?" Uncle Wu said in surprise.

Chuchen laughs. Then he explained the original thought:

"at the beginning, like you, I thought that there might be another work hidden under this painting, but I didn't find anything unusual after careful inspection. At that time, I just took it and put it into the mirror, and just swept it to the axle head, and then I found this gap."
