After seeing the envelope sent back by Li Jing, Li Shimin had a hint of laughter and crying expression on his face.

"This should be a coincidence."

Li Shimin murmured softly, and it turned out that Li Jing's layout on Annan written on the envelope and the final recommendation of Wang Xuance to take charge of Annan in the future.

At least half of this letter is praising Wang Xuance, and the remaining half is also paving the way.

It can be said that Li Jing is very optimistic about Wang Xuance. If it weren't for Shu An's disciple's words, then he might have started.

Of course, Li Jing analyzed it based on Annan's actual situation. Taking Annan naturally does not mean that Annan will become the granary of the Tang Dynasty.

This emperor naturally would not understand this. He wanted Wang Xuance to go to Annan because he was familiar with it.

Also, Annan has a long journey and has always been a bitter and cold place in the eyes of everyone, so naturally not many people want to go there.

Wang Xuance is the best choice, being able to be civil and military, and governing Annan is the best choice.

Now there is another reason, because Wang Xuance has conquered Li Jing in Annan.

You should know that Li Jing has never recommended a person like this. Of course, Li Li Shimin can see from the envelope that Li Jing is not due to any relationship and emotional factors.

Instead, I really hope that Wang Xuance will take charge of Annan, especially this letter was not taken down by Annan.

From this, it can be said that Li Jing has more than appointed Wang Xuance, but this matter is not so easy to deal with.

The reason is very simple. Wang Xuance's qualifications are still too shallow. Even in a bitter and cold place, he still controls the territory.

He is equivalent to the governor of Daozhou, and can be said to be considered a rank of officials, but Wang Xuance obviously does not have this qualification.

"This matter needs to be planned."

Li Shimin couldn't help but shook his head and said, although he agreed in his heart, it was difficult to do it in reality.

Chang'an Suburban Academy

After more than a month, Shu'an also came to the academy, and a piece of open space opened next to the academy has become the place where the carpenter lives.

Although it is only temporary, as the saying goes, there must be brave men under heavy rewards. Although some carpenters did not understand the crossbow machine.

However, they are willing to learn, and some people have tried to make some crossbow machines. Although they only have some similar shapes, they can be said to have made rapid progress.

This also made Rumu, the person who took the lead, feels very crisis and dare not relax at all.

"Master, this is the crossbow machine made by the villain."

When Rumu saw Shuan's eyes lit up, he ran and said respectfully.

Compared with the timid short carpenter before, Rumu has changed a lot now.

The main reason is that Shu An had asked him to serve as the team leader before, and his subordinates were in charge of some people, so he naturally became much more confident.

As for other carpenters, they had never seen Shu An, but seeing Rumu's appearance, they naturally knew that this old man must be a big shot.

"Well, let's have a demonstration first."

After Shu An said softly, his eyes fell on the crossbow not far away.

Because he has read a lot of information before, he is not unfamiliar with crossbows.

At the same time, Shu Kuanghu asked two guards to go to the demonstration.

"shuttle!"

A friction sound that cut through the air sounded, and then an arrow rushed towards the trees in the distance.

"bite!"

When the arrow fell on the trees, Rumu, who was beside him, couldn't help but secretly watch the expression of the master.

You should know that this crossbow was a preliminary attempt by him. After all, due to conditions before, he did not have so much material.

Unfortunately, Shu An had no expression on his face, which made this Rumu feel nervous.

"Everything is difficult at the beginning, but I don't know that it can be improved, so that the crossbow machine can be more powerful."

Shu An's eyes flashed and said, "If the crossbow machine is now, it will definitely not meet the requirements of carrying explosives."

After all, the weight of explosives is quite large, but this is a good start.

However, Shu An's words made the carpenter present look a little embarrassed.

It seems that this matter is very difficult, and it is indeed not too difficult to get them to make the crossbow machine based on the drawings.

But if you want to modify it yourself, then 99% of the carpenters here do not have this talent.

Even Rumu, who was full of confidence before, dared not speak at this time, because it is not that simple to improve.

Shu An shook her head when she saw this scene. In this era, she basically didn't think she could surpass her predecessors.

So this has also caused a slow progress in Chinese history, but he cannot ask these people to have so many.

After all, their thinking is also related to their growth environment, and this matter is indeed too difficult for them.

Fortunately, Shu An had already prepared and the information for this period was not in vain. He still found something from his memory.

The name of such a thing is called a bed crossbow, which only appeared during the Song Dynasty. Although it was much more bulky, Shu An didn't care.

"This is the drawing I designed these days. You can use it to study it first."

Shu An continued to say with her eyes flashing, there was not much emotion in her words, but no one present dared to underestimate her.

Shu'an did not stay for much here. The crossbow is just one link, and gunpowder is equally important.

As well as the cooperation between gunpowder and crossbow chariot, these all take a lot of time to get started.

After Shu'an left, Rumu and others finally opened the drawings brought by Shu'an.

In fact, although Rumu and others respected the surface, they were still unavoidable in their hearts.

So many carpenters cannot make improvements, let alone this master who doesn't seem to understand carpenters.

"This drawing design seems to be quite feasible."

"Yes, although I don't know how the effect is, my power may be stronger."

"The master is indeed a genius of the heavens. Maybe this crossbow can be really made."

......

However, after reading the drawings, a voice of discussion sounded, and there was a hint of shock in the words.

As carpenters, they naturally could see that the bed crossbow evolved from a crossbow machine, and the more important thing is that the design is more exquisite.

Many carpenters also had a hot look on their faces, because their previous performance seemed to disappoint the master.

Especially Rumu, now he felt a lot of shame. After all, he was the little leader of these carpenters, and he actually bowed his head and gave in.

"The master has orders and takes the lead in making a bed crossbow to reward ten swords."

At this moment, a guard stood up with a smile and said, obviously he was already very familiar with these people.

I used the same tricks before to make a crossbow machine, and it looked good, but this time it was still the case.
