Qin asked

When Mo Dou went to see Ying Zheng holding the glass plate, Ying Zheng was already waiting for him. Seeing Mo Dou raised his head, he asked, "Dou is here? Come and sit down. What are you holding here?"

Mo Dou hesitated for a moment, he seemed to have come at the wrong time, Ying Zheng is not in a good mood right now.

Over the years, Yingzheng has become more and more introverted, and only in front of Mo Dou can he show some true temperament, so whoever is most familiar with Ying Zheng is not Mo Dou's affiliation, even Zhao Ji does not know Mo Dou's understanding of Ying Zheng.

For example, now, although Ying Zheng's face is expressionless and his tone is not ups and downs, but Ying Zheng's eyebrows are slightly raised, which means that Ying Zheng is dissatisfied with a certain matter.

But Mo Dou is not afraid of Ying Zheng's wrath, let alone he came to announce the good news this time!In contrast, Mo Dou was more curious about what Ying Zheng was angry about.

So Mo Dou hesitated for a moment, then slowly opened the wooden box: "My lord, it's a good luck that Dou made this thing today."

The glass dish was carefully placed in a very simple wooden box by Mo Dou, but there was a piece of pure white rabbit fur under it. When the sunlight reflected on the slightly fluttering white fur through the glass, the glass dish looked even more beautiful. The ground is exquisite and clear, and even the small air bubbles produced by the flaws in the workmanship inside become beautiful and lovely.

A flash of surprise flashed in Yingzheng's eyes, he took out the glass plate and played with it for a while, his expression softened, and he said with a smile, "This is the glass made by Dou? It's really as clear as ice, and the glass next to it is really not as good as it is." One of them is worthy of fighting."

In the Warring States Period, there was glass. In the 30s, the inlaid glass jade bronze mirror unearthed in the tomb of Jincun, the northeast corner of the inner city of the Han and Wei ancient city in the eastern suburbs of Luoyang, used a lot of glass materials, but the color was as thick as jadeite. It's really incomparable with Modou's.

"My lord, you are absurdly praised." Mo Dou felt that Ying Zheng would praise the pride he had suppressed so hard, so he quickly held back, and took out another bamboo slip by the way, "The materials used for this glass, the method of making it, Fei Dou is all written here, I hope you will read it."

He can't keep making colored glazes and hand over mass production to others. He has to focus on research and development.

Ying Zheng took the bamboo slips, opened them, browsed through them, pondered for a moment, then took out a sword and handed it to Mo Dou: "Look at this sword."

Could this be the famous Qin Jian?Mo Dou took it curiously and examined it carefully.

This is a bronze sword. The sword is almost one meter long, and it is extremely sharp. Qin Jian, who is still not rusted after many years.

Seeing that Mo Dou was about to see the ground, Ying Zheng asked, "How about it?"

how is it?

Mo Dou pondered for a moment. If Ying Zheng just wanted to show off, he wouldn't have such an attitude. If he contacted again, Ying Zheng was unhappy before... So Ying Zheng was trying to find fault?

Then he can't say all the bad things!

Mo Dou thought for a while, and took out a template for answering high school history questions. No matter what, let's talk about the advantages first and then the disadvantages. In this way...it should always be right!

"First, as the so-called one inch is long and one inch is strong, this is because the sword is long and not easy to break, which is its biggest and most obvious advantage; second, this sword is extremely sharp, even more so than side swords; third, fighting can be bold In a word, this sword is immortal."

These are all summed up by Mo Dou from the information found by Baidu.

Ancient swords are actually very short, even the famous Goujian sword of the king of Yue is only 55cm, and the longest is only 60cm, but this sword is about 90cm!It is simply a miracle!

For a long time, in order to strengthen the sword body, craftsmen have added tin to it. However, as the saying goes, too rigid and easy to break, excessive tin will only cause the sword to break easily when cutting the enemy, which is why bronze swords cannot be made one of the reasons for the length.

After detection by later generations, the tin content of Qin Jian's surface is as high as 30%, but the interior maintains about 20% tin content, and its hardness is equivalent to that of medium carbon steel. On the other hand, it is very easy to break.

Therefore, at the hilt, the sword-making craftsman adopted a step-by-step width method, that is, the lower part of the sword body is wide and narrow, and one part is thinner and the other is thicker, so as to increase the elasticity of the sword.

Coupled with who knows how they added a chromium salt oxidation screen on the surface of the sword to achieve immortality for a thousand years, this Qin sword is simply a bug-like existence.

Ying Zheng looked at Mo Dou's returned sword and nodded: "Uncle said the same thing as you, what else?"

The immediate boss is not satisfied, so Mo Dou still has to pick a bone.

Mo Dou organized his language: "However, no matter how high the craftsmanship of this sword is, it is only made of bronze, and its skill has reached its peak. It is difficult to make progress in the future. If you want to plan in the long run, you need to develop ironware, and this sword is too long. Draw the sword in a hurry, fearing that it will be difficult to pull it out."

For example, Jing Ke's assassination of the King of Qin, who was almost ruined in later generations...

Ying Zheng was noncommittal, and nodded: "Yes."

These are not big problems.

Still not satisfied... Mo Dou gritted his teeth and said, "And the words on this sword..."

Ying Zheng finally had some reaction, looked at Mo Dou, and signaled Mo Dou to continue talking.

Mo Dou vaguely understood that Ying Zheng was dissatisfied, and smiled wryly in his heart. He was really a crow's mouth, and he said what he wanted. Before, he said that Lu Buwei was powerful and even controlled the military factory. Now Ying Zheng came to him because of this matter.

Ying Zheng was engraved on the sword of displeasure.

"Lu's Spring and Autumn Annals" said: "Wu Le Gong Ming."It means that the maker of the utensil should engrave his name on it.

Qin's military industry management system is divided into four levels.From Xiangbang, Gongshi, Cheng to craftsmen, they are responsible at all levels. Any quality problem can be traced to the responsible person through the name engraved on the weapon, and Lu Buwei is the highest supervisor of weapon production.

For example, the sword is engraved with "Xiangbang Lubuwei Temple Worker Ji Cheng Volunteer Cheng", indicating that the factory director who supervised the production of this sword is called "Ji", and under the factory director is Cheng, similar to the workshop director. The name is "Yi", and the craftsman who made this Ge is called "Cheng". (Note 1)

This is a very effective management method. However, it is a bit uncomfortable to have Lu Buwei's name on every sword.

"Grand Lu engraved the name on the weapon, Wu Le's name. If there is a mistake in the craftsmanship of the weapon, this trip will facilitate the investigation of responsibility."

Ying Zheng looked at Mo Dou with a half-smile: "That's all Dou said?"

What do you want from me? !Is it really good to speak ill of Xiangguo Lu Buwei in public? !

Mo Dou wanted to cry but had no tears, so he could only organize his words again: "It's just that the engraving of the name of Xiangguo on the sword is a bit superfluous, and it's time-consuming and laborious..."

Of course, if you just remove the name, it will only treat the symptoms but not the root cause. What Yingzheng really cares about is Lu Buwei's rights.

Mo Dou was forced to be helpless by Ying Zheng, but he admired Ying Zheng in his heart.Ying Zheng is only 12 years old, even a prince, and he has already recognized the threat of Lu Buwei, and he is not afraid of or attached to Lu Buwei. It is too far-sighted.

"Forget it." Confirming Mo Dou's thoughts, Ying Zheng no longer forced Mo Dou, and changed the topic, "Dou and Gu go to a temple to work."

Temple workers?

Temple workers are equivalent to the central military factory of Qin State.

Mo Dou was confused, why did Ying Zheng want to go there with him all of a sudden?
