Locked in the room, Jiang Yang took out a pen and paper and began to write.

The first step to travel to the age of firearms is unrealistic, and cold weapons must be available.

The pulley crossbow is a good choice, but I don't know if this Wang brother has made it up.

Secondly, the armor must meet all the townspeople, that is, 30,000 people.

Soldiers are more valuable than fine, and fine is in tools.

According to the current iron price, to build 30,000 people of armor, he has to pay nearly 10 million expenses, money here Jiangyang is not very worried, the liquor factory and sugar factory expansion is imminent.

In addition, there must be cavalry, Chen Zhiyong's report has already come, this time they have captured more than 4,000 war horses, and they can form a heavy cavalry.

But the heavy cavalry also needed a lot of armor, men needed it, and horses needed it!

From the present point of view, Jiangyang is short of iron, serious iron shortage, and even said that there will be a shortage of steel in the development of civil use.

Steel and steel, it makes people worry.

Jiang Yang thought about it a little more, and the next development of civil affairs is transportation, construction, clothing, food, housing and transportation, and there is no need to worry about food and clothing, that is, a lot of steel is necessary for housing and transportation.

Iron ore! Jiang Yang smashed his fist on the table, he must have it! Yes is a must!

Secondly, in addition to these, Jiang Yang knows that he has to take a long-term view, cold weapons are not the ultimate goal, and he has to think more about hot weapons.

Things have to be grasped with two hands, so that if there is an accident, it will not be fatal.

When it comes to firearms, gunpowder is inseparable.

Gunpowder first originated in the Spring and Autumn Period and the Warring States Period, and it was accidentally discovered by alchemists.

The application of gunpowder can indeed be traced back to the Tang Dynasty, but there are too few records, and rockets were used as carriers at that time, of course, not rockets of later generations, but flame arrows.

However, the usage is not proficient enough, and it can be said that it is still in the trial stage.

The development of this science and technology will go down the wrong path if we are not careful, and it cannot be said that it is a crooked road, but it is limited.

If gunpowder was used in the military when it was invented by alchemists, then from the Spring and Autumn Period to the Tang Dynasty, firearms should have developed brilliantly.

But no one will lead to the technology tree being crooked, you look at this gunpowder, high-precision military inventions are stunned to be regarded as fireworks.

If it weren't for a military accident, it might have been treated as a somewhat dangerous toy.

To get back to the point, Jiang Yang intends to promote the development of firearms, so there must be a sequence step by step, it is impossible to say that he wants to develop the next second and take out the drawings of the nuclear bomb to study.

Everything is from small to large, and there should be no less detours to take.

In history, the Song Dynasty invented the first assault rifle with a bamboo barrel as the body of the gun, but the range and lethality were not satisfactory.

Later, during Genghis Khan's expedition, the assault rifle was transformed into an iron tube gun body, which made Westerners suffer a lot.

This led to the study of gunpowder, and for a time there were arquebuses, muskets, cap guns, etc., and there were naturally some artillery pieces that were matched with them.

And then to the breech guns, machine guns, sniper rifles, and even howitzers.

Jiang Yang first set his goal on the firecracker, which is a simple theory, can be easily made, and can also give craftsmen a certain amount of experience.

The muskets were followed by earthen cannons and flintlock pistols.

The assault gun is very simple, but it has a range of 300 meters, an effective range of 100 meters, and it will be quickly eliminated when it is researched, and it cannot be installed.

So the first step is a flintlock pistol.

The first key thing for a flintlock pistol is the firing device, as for the other barrels, as well as gunpowder, etc., these are easy for today's craftsmen to have a drawing.

However, the ignition device is not a difficult thing for Jiang Yang, and he has done some research in his previous life.

Jiang Yang recorded this first, and then the musket was followed by the rifled gun, which further increased the firing range and effective attack distance.

But there are also drawbacks, Jiang Yang's target is breech guns, so these will definitely have to be eliminated.

Jiang Yang plans to cross this stage, and when the musket is mature, he will first develop the artillery, and then continue to develop the breech gun in one step.

Quickly, after sorting out the technology tree he wanted to develop, Jiang Yang began to draw it.

The body of the flintlock pistol was made of wood, but the barrel was made of iron, and the firing device and near the trigger required some small and delicate parts.

Jiang Yang constructed the entire structural drawings from large to small, and as for the precise small parts and ignition devices, Jiang Yang re-made the drawings and explained their meaning.

After the overall enlargement, this is relieved, a full dozen pages of drawings, from the concept to the molding device to why it is like this, Jiang Yang feels that he is being a teacher.

Hey, leading an era is troublesome, but Jiang Yang is not discouraged.

Of course, Jiang Yang could have given a death order to let them make and assemble according to the drawings he gave.

But in this way, let them act as tools without thoughts, and they will imprison their thoughts, and it is better to teach people to fish than to teach them to fish.

After the guns were designed, it was not finished, and Jiang Yang continued to take out the drawings.

Because this flintlock pistol is not loaded from behind, the ammunition needs to be stuffed through the muzzle and then fed in with a small hammer to press it tightly.

Therefore, this matching thing must not be missing, and the size should be appropriate.

Do you know my strengths and weaknesses, I know your depths and shallows, so that I can work with them.

After all the drawings were designed, Jiang Yang looked up and saw that the sky was already cloudy.

After packing up the sorted out drawings, Jiang Yang got into the carriage and rushed towards Wang Ji's blacksmith shop.

Because of the armor captured by Jiang Yang, Wang Ji's blacksmith shop is still smelting, but some simple farm tools have been built, shovels, hoes, etc. are standing at the door.

This is the labor gene engraved in the bones.

"Your Excellency, you're here." At this time, a guy with a dark face came out of it, and he was very excited when he saw Jiang Yang.

Jiang Yang was taken aback, took a step back, and carefully identified it for a long time before he asked uncertainly: "Wang Pengyue?" How did you get to this? ”

"Hey, accidentally, but my lord, we've researched something good!" Wang Pengyue excitedly ignored his identity, and his dark hand pulled Jiang Yang's cuffs and walked back.

Jiang Yang was confused, what are you doing?

As I walked, I heard that it became clear that this guy had made a pulley crossbow out, and he was so excited just now that he accidentally lit the fire, and the fire was extinguished, which made it so dark.

When they got to the back, a dozen shimmering pulley crossbows were lined up on the table, along with matching short crossbow arrows.

What's so special about surprises? This is called a special surprise.

"My lord, we found all these materials ourselves, you see that this crossbow string is all good ox tendon, and your lord, you see that this crossbow body is made of steel that has been refined several times."

"And the arrows of these crossbow arrows are made of the finest materials."
