The solvent configured by Mr. Liu is colorless and odorless. It is poured into the sink and immediately blends with the water.

Then Mr. Liu found a pair of rubber gloves and put them on, then picked up the Li Shizhen's 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 this sink or replace the solvent specially used to remove copper rust." Mr. Liu said while taking off his gloves.

Yang Jing quickly carefully folded the paper with the name of the raw materials used to prepare this solvent that he had just written down and put it in his wallet. It takes more than 20 different raw materials to prepare this solvent. It is better to write it down if you have a good memory than a bad pen.

"Xiao Yang, you have to remember one thing: rust on ancient copper coins is not a bad thing. The copper rust on ancient copper coins is actually the marks left by time and environment. Many times, our cultural relics workers use the thickness, color, firmness, etc. to identify the age and authenticity of ancient coins. However, it is precisely because of the characteristics of ancient copper coins that many people who make fake ancient copper coins now try to artificially make fake rust on copper coins to deceive buyers. Therefore, as long as the copper rust on the unearthed ancient copper coins does not affect the recognition of the money text, it is generally not necessary to remove the rust on the copper coins..."

"Also, removing rust on ancient copper coins or copperware depends on the situation. You cannot use rust removal methods to remove rust, otherwise it will easily damage these ancient copper coins. More often, these precious ancient copper coins will even be destroyed. Just like the two copper coins you brought today, the surface looks very rust, but in fact, most of them are earth rust. Therefore, when removing rust, you must first use a solvent for removing rust. If the soil rust is removed after a while, there is a lot of copper rust inside, we also need to mix another solvent specifically for removing rust..."

While waiting, Mr. Liu told Yang Jing a lot about the maintenance methods of ancient bronze coins and even bronze ware, which made Yang Jing feel excited.

Mr. Liu is the leading bronze and bronze ware cultural expert in the Palace Museum. This is an extremely rare opportunity for Yang Jing to come. Yang Jing wishes to record all the words Liu said with his mobile phone.

Unfortunately, the waiting time was only five minutes. After Mr. Liu talked for a few paragraphs, he was about to take out the money sword.

At this time, the solution in the sink had become extremely turbid, and the money sword soaked in it could no longer be seen.

Yang Jing took the lead and put on rubber gloves and said, "Old Liu, let me do this kind of work. Just give me some advice."

Old Liu smiled and nodded and said, "Then be careful. The hemp rope of this sword is probably rotten. Once the earth rust is removed, the whole sword is likely to have fallen apart."

Yang Jing carefully 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 when it touched.

"Old Liu, this sword doesn't seem to be dispersed. I feel quite strong when I touch it."

Hearing Yang Jing's words, Old Liu also showed a look of surprise on his face. He put on rubber gloves and said, "Don't move first, I'll see what's going on."

Yang Jing shrank his hand back, Old Liu carefully reached in, and then a surprise smile appeared on his face.

"Haha, this sword should be made of hemp rope mixed with metal wire, otherwise the sword would have disintegrated long ago. Well, if I guess it's good, this sword should have a good background."

As he said that, Mr. Liu gently held the sword and left the sink, and then placed the sword on the desk.

"Haha, Lao Cai, come and take a look. The hemp rope that weaves this sword is indeed mixed with a lot of metal wires. Look at these black thin wires, aren't they just metal wires mixed in the hemp rope? Well? These two are..."

Old Liu's face became solemn, he took out a magnifying glass and looked closer. After a while, his face showed a look of surprise, "God, there are actually a few golden threads mixed in it! This sword is definitely not something that ordinary people can have, it should be an authentic Taoist money sword!"

Hearing Mr. Liu say this, Yang Jing also saw the dark yellow filaments mixed in a small bunch of black filaments. This sword has been buried underground for many years. If ordinary metals had long since oxidized and changed color, only gold, an inert metal, can be buried underneath for hundreds or thousands of years without changing color, and at most it will be dark.

Cai Yi also came up to look at it for a while before saying, "The shape of this sword is different from the shape of the money sword in the north. I remember that this type of money sword was once popular in the Yangtze River Basin for a period of time, right?"

Mr. Liu smiled and said, "That's right, judging from the shape of this sword, it should be the Taoist money sword that was popular near the south of the Yangtze River and the middle reaches of the Yangtze River during the Jiajing, Longqing and Wanli periods of the Ming Dynasty."

The shape of this sword is indeed different from the Jinqian sword that Yang Jing had seen before. The Jinqian sword that Yang Jing had seen before had a sword grid between the hilt and the sword body, which is a guard of the sword, but this sword has no sword grid. From the hilt forward, it is directly the sword body. The whole sword looks like a stick.

Yang Jing had never seen such a strange money sword before, but when he heard Mr. Liu say this, Yang Jing immediately praised Mr. Liu.

The identification result given by the Holy Ring is that this sword was woven by Li Shizhen in 1573, and 1573 happened to be the first year of Wanli, the second year after Emperor Wanli ascended the throne of the Ming Dynasty.

"Hey, Old Liu, there seems to be words on the sword hole of this sword." Cai Yi suddenly shouted loudly. It was obviously not an ordinary discovery that everyone like Cai Yi made such screams.

"Oh, you are still very good at making ancient porcelain. I didn't see it, you actually saw it. Well, it seems to be an inscription, but it is covered with rust, so I can't see it." After looking at it for a while, Mr. Liu also smiled and joked with Cai Yi. It was obvious that the bulge of the suspected font on the sword bead made both Mr. Liu and Cai Yi very excited. The sword bead is the bulge behind the hilt of the sword, which is usually used to counterweight and tying the sword ear.

If an inscription can be found on such unearthed cultural relics that are simply inexplicable, that is the best thing, because inscriptions usually have great possibilities to explain the origin of this cultural relics.

"Good good! This sword is a standard Qiankun sword, and it is also woven with a hemp rope mixed with gold wire. There are inscriptions on the sword hole. This sword is not simple! If not, I have to study this sword carefully. Maybe it would be a big discovery." Mr. Liu seemed extremely excited.

Yang Jingxin said that if this sword can be really found out, it would definitely be a big discovery. The sword of the Medicine Saint Li Shizhen is not a big discovery, so what would it be?
