Old Liu gently touched the sword as if caressing a lover, and said with a smile: "Xiao Yang, you have found an incredible sword! Tsk tsk, there is nothing left of the Medicine Saint Li Shizhen's things except the Compendium of Materia Medica. The discovery of this sword is enough to let us know more about this great Medicine Saint."

Cai Yi also nodded and said, "Yes, this sword is really an amazing sword! It is consistent with the contents recorded in some historical books, and it has the inscription of the word Medicine Saint. This provides us with a great help in understanding the life of the Medicine Saint back then!"

Yang Jing thought for a moment and asked, "Mr. Liu, doesn't that mean this sword is very valuable?"

Hearing Yang Jing's question, Old Liu said angrily: "You young people, why do you always associate such precious cultural relics with those things? This sword itself is not valuable, but the meaning behind it is priceless! This is something left by our ancestors, and its value cannot be measured by money."

Cai Yi also said: "Yes, just like the Compendium of Materia Medica left by the Medicine Saint, can that thing be measured by money? How many people have been saved by a copy of Compendium of Materia Medica over the past few hundred years? If we really talk about the value, this book is far more valuable than the Preface to the Orchid Pavilion, The Sangluan Postscript, or Along the River During the Qingming Festival!"

Yang Jing immediately stopped talking. If he argued with these two old men at this time, he would be asking for trouble...

Old Liu said to Yang Jing, "This sword still needs some professional protection and care. We will sign something later. You can leave the sword with me first. I will take good care of it for you before you take it away. Oh, don't forget to show the sword to Old Yang when you go back. I'm sure he will be very happy to see the sword."

Yang Jing was overjoyed. Anyone who didn’t agree to such a good thing would be a fool!

The person in front of us is a serious cultural relic preservation expert. I don't know how many bronze and ancient bronze artifacts have been repaired by him. With this old man personally maintaining the sword, I'm afraid there will be no one in the country who can do a better job than him.

When Old Liu saw Yang Jing agreed, he smiled, then drained all the dirty water from the sink and filled it with water again. He said as he filled it, "You gave Old Cai and me a big surprise today. Let's see if the other sword can bring any more surprises. Judging from the rust on the two swords, it is very likely that the two swords were unearthed together. We just found Li Shizhen's Qiankun Sword, so what surprises will this sword bring?"

Cai Yi also smiled and said, "Xiao Yang is a young man with great luck. He just sent us a Qianlong blue and white five-bat-holding-longevity-shaped vase two days ago, and today he brought us Li Shizhen's Qiankun magic sword. I hope you can keep up the good work and give us two old men another surprise."

After preparing the solvent, he gently placed the golden sword made of the thirty-six treasures of ancient spring into the sink, and then just waited.

Five minutes later, Mr. Liu put on a rubber glove and reached his hand into the dark water. As soon as his hand went in, his face fell.

"Xiao Yang, I'm afraid you can't save your sword! The hemp rope that tied the sword didn't contain any metal wire, and now the sword has completely disintegrated."

"Master Liu, let it disintegrate if it wants. I am mentally prepared for this anyway. I am already satisfied to have left behind the Medicine Saint's Qiankun Sword. If I can keep the sword, then keep it. If I can't, then it doesn't matter."

Cai Yi smiled and gave Yang Jing a thumbs up.

Old Liu shook his hands slightly in the sink a few times, then took out a handful of black copper coins and placed them on the table, then turned around and continued to fish the copper coins out of the sink.

Cai Yi walked up to the table, put on gloves and began to look at the black copper coins.

In fact, nothing can be seen at this time. The copper coins are still covered with a layer of black copper rust, and you need to brush them with a brush to see the text on them.

Seeing that Old Liu was still fishing out the coins from the sink, Cai Yi simply picked up the hard-bristled brush and started brushing a black coin.

It has to be admitted that the solvent prepared by Mr. Liu can not only remove the soil rust, but also has a certain cleaning effect on the copper rust on the surface of the copper coins. Cai Yi took the brush and brushed it gently, and some black-green copper rust fell off.

After swiping it a few times, Cai Yi suddenly uttered a sigh, then he picked up a magnifying glass and looked closer. After looking at it for a while, Cai Yi said tremblingly: "Lao Liu, Lao, Lao Liu, come and take a look. Why does this copper coin look like 'Daxia Zhenxing'?"

"Huh? Daxia is really in high spirits?" Old Liu, who was fishing for copper coins, shuddered when he heard this. He didn't even bother to fish for the copper coins. He took off his gloves and went to the front of the table.

When Yang Jing saw this, he thought, okay, he’d better get it himself!

Copper coins cannot be soaked in water for a long time, especially not in heated water for too long, otherwise it will damage the ancient copper coins.

This sword was made of thirty-six ancient coins, Yang Jing already knew it, so he naturally didn't need to join in the fun, and he had to quickly fish out the remaining ancient copper coins in the sink. Who knows if there are any special treasures in it? If it is damaged, then there is really no place to cry.

By the time Yang Jing had fished out all the coins in the sink and drained out the sewage to make sure, the two old men over there had still not figured out the ancient bronze coin.

Yang Jing counted the number of copper coins. In addition to the Da Xia Zhen Xing that the two old men were fiddling with, there were thirty-five ancient copper coins, all of which were black and could not be seen in their original appearance.

Suddenly, Mr. Liu also screamed, "Oh my God, it is indeed Helian Bobo's Da Xia Zhenxing! Oh my God, oh my God..."

Cai Yi also raised his head, with an excited look on his face, and murmured: "Daxia is really excited to be among the fifty treasures of Guquan!"

Mr. Liu also said excitedly: "Yes, this is a genuine Daxia Zhenxing. I have seen the same one in the National Museum!"

Then, Mr. Liu continued, "There are now eight authentic Daxia Zhenxing coins discovered. One is in Tianjin Museum, one is in the National Museum of Chinese History (PS: National Museum of Chinese History), this one was donated by Mr. Shen Zicha, a famous ancient coin collector in the late Qing Dynasty and early Republic of China, in 1959. Another one is now in Singapore. Four were auctioned in 2004, 2010, 2011 and 2014 respectively. The last one is now missing. It is said that it was once collected by Mr. Zhang Shuxun. If this one can be confirmed to be authentic, it will be the ninth authentic Daxia Zhenxing found! No, I have to measure it first, otherwise I have no idea."

As Mr. Liu spoke, he shouted to the outside, "Xiao Zhao, Xiao Zheng, bring in the micrometer and electronic scale quickly!"
