Happy Tycoon

　　 The solvent prepared by Mr. Liu is colorless and tasteless, and it melts into the water immediately after being poured into the sink.

　　 Then Liu found a pair of rubber gloves to put on, then took the Li Shizhen money sword and put it in the water.

　　 "This sword needs to be soaked for about five minutes, and then depending on the situation, I will decide whether to increase the concentration of the solvent in the sink or change the solvent specially used to remove copper rust." Liu Lao said as he took off his gloves.

　　 Yang Jing hurriedly folded the paper with the name of the raw material used to prepare this solvent, and put it in his wallet. A total of more than 20 different raw materials are needed to prepare this solvent. The memorability is not as good as the bad pen. It is best to memorize it.

"Xiao Yang, you have to remember one thing. The rust on the bronze coin is not a bad thing. The bronze rust on the bronze coin is actually the mark left by the years and the environment. Many times, our cultural relic workers are It is the thickness, color, firmness, etc. of these patinas to identify the age and authenticity of ancient coins. However, it is precisely because of the characteristics of bronze coins that many people who counterfeit bronze coins will try to artificially make them on the coins. Fake rust deceives buyers. Therefore, as long as the copper rust on the unearthed bronze coin does not affect the recognition of the text, generally do not remove the rust on the copper coin..."

"Also, to remove the rust on the bronze coins or copperware, it depends on the situation. You can't use those rust removal methods to remove the rust, otherwise it will be easy to damage the bronze coins, and more often they will even be destroyed. These precious bronze coins are just like the two copper coins swords you brought today. On the surface they look very rusty, but in fact most of them are soil rust, so when removing rust, you must first use a solvent for removing soil rust. If there is a lot of patina inside after the soil rust is removed for a while, we need to deploy another solvent specially used to remove patina..."

　　 During the waiting time, Liu Lao told Yang Jing a lot about the maintenance methods of bronze coins and even bronze wares, which made Yang Jing very excited.

Lao Liu is the foremost expert in the preservation of bronzes and bronze wares in the Palace Museum. It will be a rare opportunity for Yang Jinglai to be killed by this person. Yang Jing would like to use his mobile phone to record all these words that Liu Lao said. That's good.

　　 It's a pity that the waiting time was only five minutes, and Mr. Liu said after a few paragraphs, he was about to take out the money sword.

　　 At this time, the solution in the sink has become extremely turbid, and the money sword immersed in it is no longer visible.

　　 Yang Jing put on rubber gloves first and said, "Lao Liu, let me do this kind of work, and you can just point me to it."

　　 Liu Lao smiled and nodded and said, "Then you should be careful. The hemp rope of this sword is probably gone. If the soil rust is removed, the whole sword is likely to fall apart."

　　 Yang Jing cautiously reached into the sink, and quickly touched the sword.

　　 To Yang Jing's surprise, this sword did not disintegrate as expected, at least it was still quite strong to the touch.

　　 "Lao Liu, this sword doesn't seem to spread out. I feel it's quite strong."

　　 Hearing Yang Jing's words, Liu Lao also showed a look of surprise on his face, and said while wearing rubber gloves, "You don't move, let me see what's going on."

　　 Yang Jing retracted his hand, Liu Lao cautiously put his hand in, and then there was a surprise smile on his face.

　　 "Haha, this sword should be woven with hemp rope mixed with metal wire, otherwise this sword should have disintegrated long ago. Well, if I estimate it is good, this sword should have a good background."

　　 said, Liu Lao gently took the sword and left the sink, and then placed the sword on the counter.

"Hehe, Lao Cai, come and take a look. The hemp rope that weaves this sword is really mixed with a lot of metal wires. Look at these dark filaments. Are they just the metal wires mixed in the hemp rope? These two are..."

Old Liu's expression became serious, and he took out a magnifying glass and looked closely. After a while, his face showed a surprise look, "God, there are even a few gold threads in it! This sword is definitely not something ordinary people can own, it should be an authentic Taoist money sword!"

　　 Hearing what Liu Lao said, Yang Jing also saw the dark yellow filaments mixed in a small bundle of black filaments. I don’t know how many years this sword has been buried in the ground. If ordinary metals have long been oxidized and discolored, only gold, an inert metal, can be buried underneath for hundreds of thousands of years without changing its color.

Cai Yi also leaned over to look at it for a while before he said: "The shape of this sword is also different from the shape of the money sword in the north. I remember that this kind of money sword was popular in the Yangtze River valley for a while, right? "

　　 Liu Lao said with a smile: "Yes, judging from the shape of this sword, it should be the Taoist money sword that was popular in the south of the Yangtze River and the middle reaches of the Yangtze River during the Jiajing, Longqing, and Wanli reigns of the Ming Dynasty."

　　 The shape of this sword is indeed different from the money sword Yang Jing has seen before. The money sword that Yang Jing has seen before has a sword grid between the hilt and the sword body~www.readwn.com~, which is also the guard, but this sword does not have a sword grid. From the hilt forward, directly It is the blade, the whole sword looks like a stick.

　　 Such a strange money sword, Yang Jing has never seen it before, but when Mr. Liu said that, Yang Jing immediately gave Mr. Liu a thumbs up in his heart.

The appraisal result given by 　　 Holy Ring is that the sword was made up by Li Shizhen himself in 1573, and 1573 happened to be the first year of Wanli, which was the second year of Emperor Wanli of the Ming Dynasty.

　　 "Hey, Lao Liu, there seems to be a word on the sword of this sword." Cai Yi suddenly yelled out loud. It is obviously not a common discovery that people like Cai Yi can make such a scream.

"Yeah, your eyes on ancient porcelain are amazing. I haven't seen it. You actually saw it. Well, yes, it seems to be an inscription, but it is covered with rust, so I can't see it." Liu Lao looked at it for a while. He also laughed and teased Cai Yi. Obviously, the bulging of this suspected font on the sword made Liu Lao and Cai Yi very excited. The sword gusset is the bulge on the back of the hilt, usually used to counterweight and tie the sword spike.

　　 Unearthed cultural relics like this kind of unearthly impossible, if you can find an inscription on it, that is the best thing, because the inscription usually has a great possibility to explain the origin of this cultural relic.

"It's so good! This sword is a standard Universe Sword, and it is woven with twine with gold thread, and there are inscriptions on the sword. This sword is not easy! No, I have to. It may be a big discovery to study this sword carefully." Old Liu looked extremely excited.

　　 Yang Jingxin said, if this sword can really be found, it will definitely be a big discovery. What is the sword of medicine saint Li Shizhen, not a big discovery?

　　PS: I would like to bow to thank the 500 for the reward of "Icy Octave".
