Yu Yao continued, "The quenching technique of the blade of this sword is very special, and it can be seen from the faint unique color! This technique, apparently to make the blade tougher and sharper, has gone beyond the scope of conventional bronze. There will never be one in modern times, and I don't believe that the old man can master it!"

Unlike iron, bronze ware generally does not need to be quenched, but there are two similar situations.

Most of the things that need to be quenched are sharp-edged tools and musical instruments. Moreover, ordinary bronzes cannot be quenched, and if they are not quenched, they will crack, and they must be high-tin bronzes.

Teng Kunwu nodded secretly, this kid is not only eyesighted, but also a master who loves to learn, "Since this is the case, it is the real thing! Why do you still say, it is really not right, and it is not right to say that it is false?"

"This short sword must be the best bronze sword of the Warring States period, this is right. Yu Yao smiled slightly, "However, you can't think that Mrs. Xu made the sword, so you can add the wrong gold inscription to it!

"Good boy!" Teng Kunwu stood up, "How do you see that?!"

This time for him, it is equivalent to saying that Yu Yao is right!

But that doesn't mean it is.

Therefore, Yu Yao did not speak, just looked at Teng Kunwu.

Teng Kunwu sighed, "That's it, you won! Now you can tell me how you see it, right?"

Yu Yao then said, "Wild and domesticated are definitely different. ”

Between masters, there is no need for nonsense.

Teng Kunwu's eyes narrowed slightly, "Can you say a few more words?"

"It's also something that can't be helped, it's not a technical problem. Yu Yao shook his head slightly, "The wrong gold in the Warring States period has to use the inlay method, but this is an ancient artifact, a heavy weapon, and there must be psychological obstacles when you chisel the groove, and it is difficult to complete it smoothly." With this foundation, Zhao Guo's seal characters are a bit special, and in the end they still show subtle clues. ”

Wrong gold is a craft on bronze ware that only appeared in the middle and late Spring and Autumn Period, and flourished in the Warring States period to the Han Dynasty.

This is a very delicate process and extremely technically demanding.

There are two main kinds of technical techniques for wrong gold, during the Spring and Autumn Period and the Warring States Period, the main method is inlay, which is also called engraving.

The inlay method is to reserve a groove when casting bronze, or after casting, engrave a groove, and then use gold wire or gold sheet to inlay into the groove.

There is also a technique called painting, which is also easy to understand, using gold clay instead of gold wire and gold flakes, which is applied to the grooves. It is more common after the Han Dynasty.

The bronze short sword that Teng Kunwu took out, the wrong gold on it, is naturally inlaid with the method.

However, this is Teng Kunwu's later mistake, and the difficulty is even greater than that of the wrong gold at that time. To engrave grooves in a bronze dagger that is more than 2,000 years old, you have to be very careful.

As Yu Yao said, even if Teng Kunwu's engraving technique is fine, the psychological obstacle is difficult to overcome.

This decision of his is grotesque in itself. Do you think it's Mrs. Xu who makes the sword, so you suddenly want to add a label to it? I won't discuss this for the time being, after all, it's his thing, and he can do whatever he wants, it's nothing more than a personality problem, and others can't care about it.

However, even if he decides to get it, his skills are fine, but it is difficult to be psychologically still. After all, this is not a mortal thing, he must like it very much, once he doesn't get it right, not only will he not be able to complete the "icing on the cake" in his mind, but he will also get a "dog's tail mink", and even destroy the heavenly thing!

This psychological obstacle makes it difficult for him to really move smoothly and neatly when he engraves the grooves.

Of course, even so, it was further trimmed, but he was not a new sword, but an ancient sword with a new workmanship, and after the trimming, there was still a difference.

In fact, if it was just this difference, Yu Yao might not be able to see the problem.

There is another obstacle here, which is not psychological, but objective, and that is the particularity of these four wrong gold fonts.

Since Mrs. Xu was a native of Zhao during the Warring States Period, the wrong gold font should be based on the font of Zhao at that time, at least Teng Kunwu thought so.

Before Qin Shi Huang unified the Six Kingdoms, the characters and fonts of each country were different. The script of Zhao State is similar to the Great Seal, but the local characteristics are obvious. One of the most important features is that it has a strong handwriting meaning.

The engraving groove is not completed smoothly, and the font formed by inlaid gold wire must have a strong handwriting meaning, so that the four seal characters that look neatly integrated on the surface will reveal a "wild" feeling.

Originally, the wrong golden seal should have been "domesticated" by the short sword!

Of course, it can be said that it can be explained in general, but to really see it, it requires a high level of vision and insight.

Teng Kunwu listened to what Yu Yao said, his expression was strange, he paced back and forth, and after seven or eight times, he stood still and said, "Give me a cigarette!"

"Didn't you quit?"

"Don't be verbose! I'll take one and continue to quit!"

Teng Kunwu lit a cigarette and took several puffs, then looked at Yu Yao, "Even if you start learning from your mother's womb, you can't have such eyesight!"

"Old man, I'm studying archaeology, and I'm lucky today······"

"Bullshit! I can't see archaeology. Teng Kunwu shook his head again and again, "Who is your master?"

"Does God hand over Master?"

"It's even more bullshit!" Teng Kunwu stomped his foot, "That's it, it's a bit taboo after all, you don't want to say it, and I don't force it." Say, what do you want me to do?"

Yu Yao was about to open his mouth when the door opened again, and the tall man bowed first. Teng Kunwu flicked his sleeves, "Say!"

Tall man: "The guest is here, I've been invited into the back hall!"

"Don't be busy talking about it first, don't worry, I won't cheat. Let's stay, let's eat together!" Teng Kunwu said, and went straight out. The tall man carefully put away the camphor box.

"Hey, old man, I still have something to do at night!" Yu Yao shouted.

Teng Kunwu walked as fast as the wind, walked directly to a small door at the far edge of the house in the courtyard, opened the door and walked in.

"Old man?" Yu Yao had no choice but to follow closely. Behind this small door, it turned out to be not a room, but a corridor. After passing through the corridor, we came to the second courtyard.

"You ran here from Jiangzhou, what can you do at night?" Teng Kunwu opened his mouth at this time, "It's cheap for you! Can anyone eat my food?"

Yu Yao raised his eyes and saw that this second courtyard was really different from the first courtyard, the first courtyard was empty, but in the second courtyard, there was the fragrance of birds and flowers, and there was only a path between flowers and plants.

The main house is still five, and there are no wings, but under the red tiles, there are no bare red bricks, but they are painted beige, and the doors and windows are no longer painted green, but vermilion.

The double door in the middle was open, and the sky was already slightly dark, but the inside was brightly lit, and you could see a lot of antique furniture.

Teng Kunwu walked to the door, and a person inside also came out.
