In fact, this trick naturally had an effect, and these carpenters showed a look of excitement on their faces.

Ten yuan is not a small amount for them, although some people are from Yangzhou, but they still plan to establish a foothold in Chang'an, or go back in the future.

Although there is a lot of salary every month, ten times is not a small amount.

Of course, the most promising one among them is Lu Mu, after all, he is the only person who can make a crossbow machine before.

The previous usual money reward was taken by Lu Mu, so this time Lu Mu is also bound to win.

Shu An didn't know the thoughts of these carpenters, but Shu An frowned slightly at this time.

The reason is very simple, the progress of gunpowder research has been slow, not that these Taoist priests do not work hard.

But there really isn't much way to do it, the reduction in the volume of explosives means that the meaning is different, and the scientific and technological content in this is not something that can be easily solved in this era.

Shu An also took it for granted before, but Shu An did not lose confidence.

Anyway, he has only been researching explosives for half a year, and it is already very gratifying that he has already achieved such results.

"Sure enough, there are some things that can't be rushed."

Shu An thought silently, he understood the truth that if you want to hurry, you can't reach it, but this matter can't be ignored by him.

If gunpowder can be used, then HNA can be regarded as having real confidence, otherwise, if you want to make those natives submit, it is far from enough to rely on cold weapons.

.......

In the following days, Shu An began to live a life of three points and one line again, basically a cycle of several places.

Occasionally, I'll have to check on the progress of the carpenters, but it's not that easy.

After all, drawings are just drawings, and if you want to turn them into reality, then there are also a lot of difficulties.

Such a peaceful day made Shu An feel very fulfilled, but such a day was broken by someone who came.

This person was none other than Li Shimin, but at this time, Li Shimin was curiously looking at the many people in the open space next to the academy.

"Is this a crossbow?"

Li Shimin naturally recognized this kind of thing at a glance, he had heard from Baiqi before, that is, Shufu had recruited a lot of carpenters.

I didn't expect to be this one, as a member of the army, Li Shimin still read a lot of military books.

There is also a lot of understanding of the crossbow machine, although it is a battlefield weapon, but it also has a lot of drawbacks.

For example, it is too bulky, and the number of controllers needs to be at least three, and it is useless if the number of crossbow machines is small.

But if there are too many, even Li Shimin can't afford it, but there is a feeling that it is a pity to abandon the tasteless food.

Of course, in the end, it was abandoned, because what the crossbow machine can do, then the bow and arrow can also do.

Li Shimin didn't bother much about this matter, he was more concerned about what his father was doing with this ballista.

"What are you doing?"

After Li Shimin became interested, he did not go in to find Shu Mansion as soon as possible, but pulled a carpenter and asked.

Unfortunately, the carpenter that Li Shimin pulled was Lu Mu, probably because of his short character, even Li Shimin was a little surprised.

"This young master, we're making bed crossbows."

Lu Mu showed a hint of respect and said in his voice, and there was some flattering flavor in his words.

It is important to know that when these people arrived, they were observed by Lu Mu, but he found that the guards around him did not react.

knew that this young man might be the young master of the mansion, after all, the gorgeous clothes on his body had already exposed his identity as either rich or noble.

"Bed crossbow?!"

Li Shimin's face was even more puzzled and said, there was no such thing in his mind.

Fortunately, Lu Mu seemed to see the doubts of a noble son, so he immediately explained, if it were not for the fact that the old man spoke.

Even the carpenters didn't know what a bed crossbow was.

Under Lu Mu's explanation, Li Shimin's face showed a sudden realization, it turned out to be a more powerful weapon than a crossbow machine.

Despite this, Li Shimin didn't care, because in his eyes, the power of the bed crossbow was just two or three percent added to the crossbow fuselage.

It still can't change the defects of the crossbow machine itself, not to mention that it's just a drawing.

Before seeing the real thing, Li Shimin naturally wouldn't have any interest in the bed crossbow.

It's a pity that although Li Shimin knows what these carpenters are going to do, he still doesn't know what Yafu is going to do.

After thinking of this, Li Shimin did not hesitate and stepped directly into the academy.

On the side, Lu Mu's face was a little disappointed, as if this young master didn't have much impression of himself.

Of course, Lu Mu didn't know Li Shimin's identity, otherwise he would definitely not dare to do so.

Shu An was already waiting in the academy, and there was also some speculation about Li Shimin's stay in Shu An outside.

Obviously, this emperor's curiosity is not ordinary, and it is only a problem if he does not see it in such an obvious place.

"Why did the people of the world come here this time?"

Shu An didn't say much, and went directly to the topic and said, obviously knowing that the emperor in front of him had something to do.

"Before I talk about it, can my father tell the people what this crossbow is for?!"

Li Shimin's face showed a hint of curiosity and asked, obviously he still felt that this father would not do useless work.

Faced with Li Shimin's question, Shu An was slightly stunned, and seemed to be a little silent, but then the voice sounded slowly.

"For the conquest of the sea."

"You must know that the sea has many huge sea beasts, and only sharp weapons can cause damage."

Shu An didn't fully say what he thought, but the current revelation of this has already surprised Li Shimin.

This emperor suddenly remembered the shipyard that his father wanted before, was it just for shipbuilding?

In an instant, the emperor's face began to complicate, and Shu An on the other side was not at all strange.

The reason is simple: there is a natural fear of the sea in this era.

In particular, the closer the ocean villagers, there are even sacrifices to the sea god, and people who go out of the ocean are easy to get lost.

So he was even more afraid, originally Li Shimin was afraid of ghosts and gods, but now he naturally doesn't want to touch the ocean.

Naturally, after Shu An talked about this matter, even this emperor's face changed a lot.

If he could, Shu An wanted to pull this emperor into the gang, but unfortunately, looking at Li Shimin's expression, Shu An knew that it was impossible.

Of course, Shu An didn't have much hope in his heart, anyway, this emperor didn't cause him trouble, and when HNA's interests emerged, I don't know if this emperor would regret it.
