The Dafu ship is naturally not easy to build.

At least after getting the drawings, even if you work hard, it will take one or two months to build them. What's more, those craftsmen are not familiar with the first construction, so it will definitely take more time.

But there is no need to worry. After all, Li Shimin will have to fight Goguli for one or two years, so there is no need to worry in a short period of time.

Fang Jun began to busy making the muskets again, and then made them bigger and made them into cannons, trying to make them fit on a carriage.

This took some time to make it, but as time went by, the craftsmen successfully created one hundred muskets.

First, let someone check the advantages and disadvantages of the copper tube. If it is too thin, it will be discarded and remade, and then continue to test the power.

In fact, Fang Jun has been studying steel for a long time, and has been studying it for a long time. It has improved the quality of steel to a certain extent, but it is still a bit difficult to reach the point of practicality.

Fang Jun completely forgot how to improve the quality of iron, and only remembered to add more charcoal to let the craftsmen try more, so the progress was slow.

The first batch of muskets were made, with a total of 100, and the quality looked pretty good.

Fang Jun sent it to members of the vanguard team.

During this period, the members of the vanguards were training, and it was very hard and had a rare rest time. They had already practiced very well and were almost able to pass the exam.

When Fang Jun fired the musket into their hands, they were surprised and a little confused.

"The things in your hands are called muskets. They may not be useful at a long distance, but they are almost invincible at close range! The usage of muskets is very simple. Fill the guns into them with gunpowder and iron beads, then ignite the leads, and aim at the enemy to fire! I will demonstrate it to you, and you will attack the target not far away later!"

Fang Jun said to them.

When the vanguards heard this, they couldn't help looking at each other.

There are many people nearby.

Liu Hongji, Niu Jinda and others rushed over, as well as Cheng Chubi's soldiers.

Li Shimin attached great importance to muskets and wanted to see how powerful the combat power was, so he specially told them to come and take a look.

Fang Jun didn't say much, picked up the musket and pointed it at the target not far away, lit up the lead and fired a shot.

"Bang!"

With a loud bang, the flames ejected from the barrel, causing the barrel to vibrate a little, and countless iron beads burst into flames and hit the target not far away.

"Just launch like this, you all see clearly. It's very simple! Now, you 100 people are in a queue. I give you orders and you can just launch it!" Fang Jun turned around and said to everyone.

The people in the vanguards were shocked.

They have never seen such things at all, and have never even heard of them before. Now that they have obtained them, they can spray out fire. How can they not be surprised?

"General Fang, can this thing kill people?"

"Of course you can kill people, otherwise what else can you do! Say less nonsense, do what I said, aim at the target not far away!" Fang Jun said.

"yes!"

The vanguards naturally did not dare to neglect them, and hurriedly stood up and pointed at the target not far away.

"Open fire!"

With a command, the leads in the hand of the vanguards were immediately ignited. In an instant, there was a loud bang bang, and countless iron beads exploded not far away, and flames shot out of the barrel. The scene was quite terrifying.

All the targets not far away were hit in an instant, and countless small holes emerged in an instant, and some were knocked down directly.

When everyone saw this scene, they were stunned.

"That's how it is used! But now there is a problem, that is, this item takes time to fill ammunition. Sometimes it can only be fired! So I thought of a way, that is, the two of them stand together, one in front and one behind, the one in front and the other in the back, and the one in the back can shoot! You can fill ammunition between the gaps in the shooting!" Fang Jun said: "If you use it well, you will be invincible within 150 steps!"

Hearing Fang Jun say this, the vanguards immediately looked at the things in their hands and looked at each other.

On the other hand, Liu Hongji, Niu Jinda and others took a deep breath and were also a little excited.

The effect looks great and powerful.

This has just been done. It is said that the prince consort of the house has decided to do it very much and can open the city wall with one shot, which may be more effective.

Liu Hongji and Niu Jinda were both veteran generals and soon realized the importance of this thing. Liu Hongji couldn't help but sigh and said, "No wonder Your Majesty attaches so much importance! Your Majesty said before that this thing is a key weapon for siege. I can't believe it, but at this moment, it's indeed extremely powerful!"

Niu Jinda was a little unhappy when he heard this: "Duke, he is still young! He should have read books at home for a few more years, rather than running out to fight!"

Liu Hongji looked at him and smiled, "You asked him to study? If you say that, I'm afraid that the master of Chang'an will swear you to death! Who doesn't know that this general in Chang'an is knowledgeable now? Don't look at him as young as he is very smart!"

Niu Jinda actually didn't have any objections to Fang Jun, but he just didn't feel happy about him.

After all, to him, Fang Jun is his superior.

He was a general with great military achievements. When he came to Youzhou, he was ridden by a yellow-haired boy on his head. How could he feel comfortable?

This is how it looks like this in the past few days.

Fang Jun naturally knew why he was, so he simply ignored him. Now that he heard Liu Hongji say this, Niu Jinda seemed even more unhappy.

But he had no choice but to hold it in, and he knew that Fang Jun was very famous in Chang'an.

"This musket can be reported to Your Majesty, it is indeed not an ordinary thing. If you use it well, you can decide the situation of the battle!"

"This thing is still dangerous and easy to explode. If you are not controlled carefully, it will cause endless disasters and you need to be careful!"

"This thing is most afraid of fire, such as gunpowder, which is a dangerous thing. It can be made, but it cannot be used on a large scale!"

Liu Hongji discussed with several generals for a few words, nodded, and did not hesitate, and immediately began to write a memorial to Li Shimin.

...

On the other hand, the firearm experiment was successful, and the vanguards were very excited. After all, this was a rare thing for them.

Fang Jun asked them to fire a few more times, get familiar with the muskets, and then let someone take them back.

There is another major problem that needs to be solved for muskets, that is, the barrel is prone to heat up, and once it overheated, it will explode.

Therefore, Fang Junhai needs some hard work here.

Putting away the muskets and letting the craftsmen continue to think about it and solve the problem of gun barrel firing. Fang Jun thought about it and felt that it was necessary to call Chiji, Tuoli and others over.

There is also the work of natural craftsmanship. Before Fang Jun came to Youzhou, he had already ordered people to do it. However, the recent periods have not been very good, so it is estimated that it will be done again. Fang Jun wants to call all the craftsmen and disciples to Youzhou first.

If those craftsmen cannot do good work, then they can only do it themselves. At least, he knows what to do with some things!

This must be done.

When he got home, he did not hesitate and immediately called Tiexin to send someone back to Chang'an.

Since Chiji and Tuo Li were both coming, Chen Yunzhu had to come, and he didn't know if they were willing or not?
