Chapter 220

At present, the equipment of the soldiers and guardians of the territory is made of leather armor and black iron.

It's nothing to see now. When we really confront the enemy, we will be very passive.

Li Tiezhu thought about it carefully and said definitely: "little Lord, we have inherited the craftsmanship of our own black iron workshop. So everyone has the skill to build this kind of weapon and equipment! As long as the materials are sufficient, the whole workshop will make all efforts to finish the production soon. "

Zhao Fengnian nodded, took out two drawings from his arms and put them on the table.

These two drawings are the crossbow arrow and plow that Zhao Fengnian once knew.

"These are two kinds of objects I designed. Take a closer look. I'll tell you about the key points..."

Later, Zhao Fengnian and Li Tiezhu explained the making methods and functions of these two objects.

Because the world's long sword, sword and other weapons have been very perfect, there are all kinds of specifications, but bow and arrow weapons are not widely used.

The speed of the world's warriors is too fast, it takes time to draw the bow and aim, and if the firing speed is not fast enough, the warrior can easily avoid.

Therefore, Zhao Fengnian thought of the crossbow, which has a powerful lethal weapon. A good crossbow can even be as lethal as a rifle bullet!

Fortunately, Zhao Fengnian was also a military fan in his last life. There are still some studies on this kind of cold weapon, so it is not difficult to draw drawings.

The difficulty lies in several fine parts, which need Li Tiezhu to find a way to do it.

However, this is not a problem if we want to inherit it from generation to generation by Li Tiezhu.

In addition, Zhao Fengnian also designed an arrow box, which can automatically drop the arrow into the track by pulling the bow string and touching the arrow box mechanism, thus saving the time of manual arrow loading.

Another is the choice of bowstring, Zhao Fengnian chose to use animal tendon and steel wire.

The tenacity and elasticity of animal tendons are very good, especially for some spirit animals.

However, it is not easy to get the tendons of spirit beasts above level 4, so Zhao Fengnian plans to replace them with steel wires.

Before Li Tiezhu's experiment, Zhao Fengnian had ordered to record the refined iron produced by different proportions.

It is to find out some specific refined iron and make use of its performance to do something that conventional refined iron can't do.

When Li Tiezhu heard that Zhao Fengnian mentioned this crop, he remembered that there were several kinds of refined iron, especially suitable for making the steel wire Zhao Fengnian said.

I can't help but feel more confident about this task.

Finally, Zhao Fengnian explained the working principle of the leverage bar used in the upper chord.

In fact, it is a simple principle of leverage. As an old craftsman, it is easy to understand the method, and there is no difficulty.

After explaining the first drawing, Zhao Fengnian explained the second one, the function of plough.

Plow is actually a farming tool that Zhao Fengnian thought of for a long time, because most of the agricultural tools used before were black iron, that is pig iron.

The farm tools are very brittle, and they will be broken if they are not properly applied. Therefore, the plough with stronger force can not be made of black iron.

This is the refined iron has been developed, and it is not long before spring ploughing. Zhao Fengnian put it on the agenda.

In fact, the production of plow is not difficult, but some angles need experiments. After the experiment, large-scale production can be carried out.

In addition, the main structure of the plough, Zhao Fengnian, also plans to use steel with stronger structure, so that the overall weight will be lighter than that of wood and more convenient to use.
