This "scabbard", after being combined with the sub-sword, is also a sword itself, but after being separated from the sub-sword, it becomes a scabbard again.

Because the "sword scabbard" has been divided, a sheath has appeared at the bottom, and the inscription is very close to the sheath, so Yu Yao looked at the two-character inscription again, and there was one more way, that is, to use a strong flashlight to shine from the sheath, but his eyes were still fixed on the two inscriptions.

The inscription of these two characters is not hollowed out to the end, but in this way, between the calligraphy and painting, there can also be some faint light.

Yu Yao finally understood.

This inscription is not a lack of pen and many strokes, not high and low, but has two layers! The distance between the two layers is very small, and some parts are hooked, so it is extremely difficult to recognize.

Yu Yao first determined that this was indeed the golden text of the Shang Dynasty.

Jin Wen is actually a general term, because it appears the most on Zhong Ding, so it is also called Zhong Dingwen. Since it is a general term, it also needs to be distinguished, roughly speaking, there are Shang Dynasty Jinwen, Western Zhou Jinwen, Eastern Zhou Jinwen (Spring and Autumn Period and Warring States) Jinwen, Qin and Han Jinwen.

The Shang Dynasty Jin Wen is the most difficult to identify, because this is the initial period of the Jin Wen. Although there were bronzes in the Xia Dynasty, the Jin Wen was only found after the Shang Dynasty moved from Pangeng to Yin.

As a professional in archaeology, Yu Yao has the ability to identify Jin Wen, but if he coldly tricks a few Shang Dynasty Jin Wen out, he may not be able to recognize it.

But now he can.

Because according to the characteristics of the ancient sword, he is roughly a little bit counted.

The inscription on the upper layer should be: Chengying.

The inscription on the next layer should be: Hanguang.

Chengying, Hanguang, and Xiaolian are three famous swords, also known as the three swords of Shang Tianzi, but these three swords disappeared very early, and there was no movement after the Spring and Autumn Period.

According to legend, these three swords were once obtained by the same person, who was named Kong Zhou, a patriot in the Spring and Autumn Period.

In "Liezi Tang Wen", Kong Zhou said: I have three swords, but the son chooses. One is said to contain light, which is not visible to see, and does not know what it moves, and what it touches is also boundless, and it is imperceptible to things through things. The second is said to be a shadow, will be a cool friend, when the sun and sunset are dusk, the north and observe it, faintly if there is a thing, do not know its form; Three days of night practice, the day sees the shadow but does not see the light, the night sees the light but does not see the form; its touch is also, passing by, with the passing, feeling sick but not bloody······

The general meaning is relatively easy to understand, and it's okay if the details can't be explained accurately, because it's mainly bragging. To put it mildly, it uses exaggerated rhetorical devices. For example, "passing through things and not realizing things", that is impossible, and even if it is possible, it has nothing to do with the sword itself, unless there is super speed.

When Kong Zhou said this, it was because a man called Lai Dan asked him to borrow a sword to avenge the murder of his father. Because the black egg that killed his father (the name is very associative) is very powerful, he can defeat a hundred people, and he may have practiced magic skills such as the golden bell hood iron cloth shirt, and the sword and arrow beckoned him, and he couldn't even leave a mark.

So when Lai Dan heard that Kong Zhou had the miraculous Three Swords of Shang Tianzi, he wanted to borrow one for revenge. Because Kong Zhou's Shang Tianzi's three swords, no matter who used them, they were very awesome, and there was once a child with a sword, who once defeated the invading army of the three vassal states.

By the way, there are many myths and fables in the content of "Liezi", so all the above exaggerations are nothing at all.

Lai Dan found Kong Zhou, and Kong Zhou introduced these three swords in this way.

In the end, Lai Dan borrowed Xiaolian, followed the lurk, and took advantage of the drunkenness of this black egg to make three swords in a row. But the result is the same as Kong Zhou's description of Xiao Lian, "its touch is also, it passes by, and it goes with it, and it feels sick but not bloody." The black egg didn't die at the time, but woke up feeling uncomfortable.

In fact, before Kong Zhou lent Lai Dan the sword, he told him that although these three swords were awesome, they could not kill people, and Lai Dan had to take revenge before lending him a try.

According to his meaning, the light, the shadow, and the night practice actually contain the characteristics of three things, namely light, shadow, and wind, and what is affected is not the human destiny, but a kind of subtle influence.

Therefore, there was no news from Hanguang, Chengying, and Xiaolian after the Spring and Autumn Period, and some people thought that these three swords were not swords, but were just ancient swords, so it was normal for them to disappear, because they might not have existed in the first place.

Liezi is a Taoist himself, so some researchers say that these three swords are about the three states of human cultivation, and the three swords are three symbolic meanings. It also means that there is no physical object.

However, Yu Yao has never believed these claims.

To be exact, whether it is a metaphor or a symbol, this is understandable, but Yu Yao has always felt that there must be a real thing! Even if the real thing is not so miraculous, at least it is a little basic. The mythical Ruyi golden hoop stick, the Dinghai God Needle, has to be used when Dayu controls the water.

And in the Shang Dynasty, bronze swords began to appear, and the Son of Heaven had a few awesome swords, which was reasonable.

Looking at it now, Yu Yao is right.

I saw two of them at once!

Moreover, light and shadow complement each other and become one. Light and shadow are one!

If you think about it, it should also be one. Even in the story of "Liezi", what Lai Dan took away was an independent night practice.

After Yu Yao's explanation, Xiao Ying and Zhong Yu were overjoyed. This kind of ancient sword treasure wrapped in legends, not to mention that it must be priceless, but to say that the kind of impact that gives people and the sense of mental excitement brought by it is also great.

"I said that the evil spirit is so heavy, I see!" Xiao Ying suddenly realized.

"What?" Yu Yao and Zhong Yu were puzzled.

Xiao Ying pointed to the sword and said, "These two swords must have not been separated for a long time! Although they are one, their state and aura are still different, and they can only be normal when they are separated and combined, and they cannot be separated for a long time, so they have a strong evil aura." ”

Xiao Ying said, then removed the talisman array, and then touched the sword body with light, "It's just, what the hell is this made of?"

"It's supposed to be something like glass. Yu Yao responded, "It's just that special materials may have been added and special smelting techniques were used." ”

In fact, there was glass in ancient China very early, and gadgets can be traced back to the Spring and Autumn Period and the Warring States Period, and in the Northern Wei Dynasty, there was glass blowing technology.

However, glassware was not used on a large scale in ancient China. The main reason for this is because of ceramics. In foreign countries, there was no porcelain technology, and glass (glaze) was used in relatively small quantities in ancient China, or as an ornament.

Now this light-containing sword, which belongs to the Shang Dynasty, is not glass, but it can be regarded as the ancestor of glass, and its hardness and toughness far exceed that of glass.

However, the manufacture of this kind of thing may be extremely fortuitous, and a certain person, a certain technology, or a certain material may no longer be obtained.

The three of them were immersed in surprise for a while, and discussed again.

After a while, Yu Yao went to check the gloomy wooden sword box and oilcloth bag that came with it again, "Who owned such a rare thing in the first place, and why was it hidden?"
