A horizontal knife is more straight than a straight knife, and it will be sharp. It is too hard, has no cutting function, and has no buffering function of recoil force. This is a bit similar to Tang Jun's personality.

As for the machetes that appeared in the Song Dynasty, they were indeed suitable for military use, but there was no way to lose the steelmaking method. If the iron was made into a horizontal knife, it would not be practical at all. It would probably be broken in a few strokes and could only be widened and thickened.

For Datang, which has excellent steelmaking technology, it is a bit wasteful and unnecessary.

After drawing the saber, Zhang Jun thought about it and drew his dog's legs: "This is a knife of a certain idea. I think this is more conducive to chopping and slashing battles and has greater damage. You might as well try it."

"It's probably not easy to carry in such a shape."

"It's okay, but I've tried it."

"No." The old craftsman carefully put away two sketches.

Zhang Jun originally wanted to mark the size, but he didn't know much about the weights and measures at this moment, and was afraid that if the marking was wrong, it would delay the matter.

In the Tang Dynasty, there were strict weight and measurement standards and implementation systems. Even the scales used by private individuals had to be taken to the government to level the school every year, and they could only be used by qualified ones. There were also laws and regulations specifically targeting weight and measurement, which were quite strict.

The punishment starts with a big move of sixty-seventy-seventy-foot-five-shot, which means to beat people to death. But if you have negligence, it is the same crime.

In the Tang Dynasty, inaccurate meter-shaped fights were used as a thief for the crime of thieves, which was to start with fifty beats.

The Tang Dynasty law stipulates that if a thief acts but fails to get something, he will be flogged fifty or beaten one foot and sixty or sixty. If he steals the thing, he will be sentenced to two years in prison, and he will be sentenced to three years in prison and ten horses in prison.

Those who stole weapons but did not get anything, would flow for three thousand miles and five were twisted. Five were killed.

The size of the Tang Dynasty was a little smaller than now, ten feet and ten feet, four feet were a piece, about twelve meters of cloth, which shows how strict it was.

In the Tang Dynasty, cloth was used as money, and like copper coins, it was the main currency and the main currency, so this was used for sentencing.

Therefore, in Bai Juyi's "The Charcoal Selling Man", half a piece of red gauze is tied to the cow's head to fill the charcoal straight. It is not that I don't pay, but that I feel that I'm giving less. Shine is a kind of Luo, and silk and Luo were still very expensive in the Tang Dynasty.

Another poem by himself, "The New Silhouette of the New Silhouette, Feelings and Songs", is to show that he was so happy that he could not help himself with a new Silhouette.

This second-generation official, from the second-rank official, can be so happy that he can't help himself with a new silk jacket. Just think about it, can it be cheap?

The officials at that time were still very honest and honest. It was normal for the prime minister to not afford a house and live in a public house for the rest of his life and be scolded by his wife every day. (The power of the prime minister in the Tang Dynasty was not as great as he imagined)

...

Seeing the old craftsman carefully put away the drawings, Zhang Jun was not saying anything. As a big craftsman who specializes in making weapons, size is not a problem for him, and it may be even more in place than himself.

Moreover, this also involves the deformation of the knife. All aspects of thickness and curvature balance are not so simple, and they have to be tried over and over again. These craftsmen have fixed processes, so there is no need to say much.

Of course, this is not a matter of five days. The old man will create a suitable horizontal knife for Zhang Jun within five days, but you have to wait when the two changed tools can be prepared.

After explaining the matter, Zhang Jun hesitated at the hemp paper in front of him with his fingers.

It’s not the kind of impulse and hesitation that we want to draw a few strokes when holding a pen and facing the paper. He is thinking about it.

No matter what, military power will be his reliance for a long time, or in other words, his reliance on his future life. Then, changing the military structure and increasing the attack power of the army is the most urgent thing at the moment.

Although the Tang army was invincible in this era, it was not without shortcomings, nor could it be impossible to improve it. Especially after almost a long time, there were internal operations, and everyone was almost the same.

He was thinking about where to start now.

The change of the knife cannot be counted, it is just a small step and has little effect.

Because he had practiced riding and shooting, he had some information about bows, crossbows, and equestrians in his brain. Unfortunately, most of them are modern things and it is impossible to achieve in this era.

With that craft, you can directly build a gun. The craftsmanship and complexity of modern crossbows are much greater than that of guns.

"My husband, do you have something to do?" Lord Bo asked carefully. Everyone stood here and watched Zhang Jun dazed. This was not a big deal.

Zhang Jun turned his head and looked at him, thought for a while, and raised his hand to draw on the hemp paper.

It paints a divine arm crossbow, which was invented in the Song Dynasty and is known as the strongest crossbow in history.

Unfortunately, this kind of crossbow was actually lost. What he drew was only a fake imitation by modern enthusiasts after checking countless materials. Only by making it can we know what extent it can be.

But it feels that the restoration is quite high, and the masters can also add to the materials in all aspects at this time. He just provides a way of thinking, which should be OK.

First draw a schematic diagram, and then separate the ring, arm, bow and machine to explain in detail. The problem of strings does not need to be considered, that is the craftsman's business.

There are also arrows. Half the power of the Divine Arm Crossbow is on the arrow, and it needs to be specially made.

The effect of this crossbow is to penetrate the damage vigorously, but it is enough in this era. Just break the armor, and you can add a blood slot to bleed.

There is also a bow wheel. Although it is impossible to make a full steel crossbow, the bow wheel should be OK. It doesn’t matter if this thing really doesn’t work, but once it succeeds, it will make a profit and the rate of fire will immediately increase.

After obtaining the methods of making steel and crossbows in the West, a steel crossbow was once made, but the volume and weight were too large and not practical.

"Mr. Is the painting a crossbow?" the old craftsman looked at it for a while and asked.

In fact, several people saw it. Zhang Jun changed the crossbow machine to a modern style, which is more practical, and the others are similar to this era.

"Wait." Zhang Jun carefully drew each structure clearly and marked it with sizes. Because he was constantly converting, he didn't dare to talk. Fortunately, his hard drive-like brain could help, which made him much easier.

"By some calculations, this crossbow should be able to shoot three hundred steps and can be hard armor. A father-in-law can look at this steel wheel carefully. If it can be made, the yellow-mouthed boy can also open a crossbow, so he is afraid that it is too difficult to make it."

"Three hundred steps?"

"I have learned a little bit about the mathematics and repeated calculations to get this conclusion." Zhang Jun marked the composite method and size on the crossbow section diagram, but still did not write the materials, but just wrote the requirements.

Multi-layer composite technology is not difficult in the Tang Dynasty and can be realized. Even craftsmen can already make sealing techniques at this moment.

Writing is not a big problem for Zhang Jun. He has copied many Liu Yan's posts, and he has probably seen and written all the words.

So it is useful to learn a few more things if you have nothing to do. Look, this is what you need.

(Popular Science: In ancient times, the height of a person is a summer ruler. One foot is only sixteen centimeters short, and it has nothing to do with weights and measures. One foot is about one meter six, but it is actually less than that, two meter two or about one meter eight.

Dayu took his height as meter and ten as a ruler, which was for his husband. Later, the weights and measures of each dynasty were different, but it has been growing from ancient times to the present. So why did the height size remain the summer ruler?
