After Shu Maanhu also left, Shu An couldn't help but slowly close his eyes, as if thinking about something.

In fact, this time he already had an idea, and after this period of research and development of gunpowder, it can be said that Shu An has made some progress.

At least the simple gunpowder has been made, but the effect is a bit like a larger cannonball.

The barrel was about half a meter high, filled with gunpowder, and if it exploded, it would be less than one-third of the power of the grenade before the crossing.

It can be said that there are some chicken ribs, at least it is far from the bronze cannon in his mind.

However, it does not mean that this simple gunpowder is useless, as long as the quantity is sufficient, then it can also cause great power.

The sound of the explosion of gunpowder is even more frightening for the war horse, and there will be chaos on the battlefield at that time.

So this time Shu An went to the border for this one thing, after all, this time Jieli is very likely to plunder in winter, if it is well planned.

Then it is not impossible for these Turks to suffer a defeat, and it is not bad to destroy even some of them.

At least let these young people in Datang die less, and he is not unable to earn money back by taking advantage of this.

.....

In three days, 300,000 guan was quickly raised, and the original Shu Mansion originally had 100,000 guan, and it was not difficult to borrow another 200,000 guan.

These students of Shu'an didn't hesitate much, and even those big families even had to pay 200,000 yuan alone.

Even if Shu An knew about it, he couldn't help but sigh, sure enough, these families are really rich, and as for the interest, these students refused even if they were Laifu.

Obviously, these people have a plan in their hearts, and they don't think that this teacher can afford to pay back the money.

The ability to absorb gold in heaven and earth is still obvious to all, and it is in this situation that it is better to let the teacher see the mind of some of their students.

After all, Shu Anke has always had no trouble with students, and even if there is, it is not a difficult thing.

It was under such circumstances that these students quickly prepared the money in the face of Shu An's instructions.

Even on the first day, it was prepared, but 300,000 guan is not a small amount, and it will take a lot of time to ship.

After handing over to Li Shimin's guards, Shu An looked at Li Junxian with some weirdness on his face.

"Jun Xian, how many people did the hundred horsemen bring this time?"

Shu An couldn't help but be a little curious, he didn't know much about Baiqi.

But this is also normal, don't say that he doesn't understand, even the entire court doesn't have many people who understand, how many people are in the hundred horses.

All in all, except for Li Shimin, there is only this Li Junxian in front of him.

"This time, Your Majesty ordered to select one hundred elites among the hundred horsemen to protect An Xuangong."

Li Junxian did not hesitate to speak out, and did not hide An Xuangong's thoughts.

"A hundred people is enough."

The smile on Shu An's face became thicker and he said softly, and there seemed to be a hint of deep meaning in his words.

However, Li Junxian looked at An Xuangong's face with a smile, and couldn't help but have a bad premonition in his heart.

The next day

Without anyone knowing, a total of five carriages, including Shu An, and the 100-man cavalry that followed slowly formed a team and slowly left Chang'an.

At this time, there was something strange on Li Junxian's face, that is, this An Xuangong actually made these elite horsemen become horsemen.

And these barrels seem to contain some kind of soil, at least Li Junxian didn't see anything.

For a while, the commander of the hundred horsemen couldn't help but fall into deep thought, and he didn't know what An Xuangong's intentions were.

"I haven't been far away from Chang'an for a long time, but I have some nostalgia."

In the carriage at the head, Shu looked at the official road and muttered softly.

If you want to know what he is most familiar with, then it is natural to have to be official.

In the past few days, he has finally made dozens of powder kegs out, although one word may not be powerful.

But dozens of words, then the weight is also enough, enough to set up an ambush.

Of course, these powder kegs also caused a lot of doubts, but every time Shu An smiled mysteriously and didn't explain anything.

After all, if you explain it, people in this era may not understand, it is better to see is believing.

......

Just as Shu An was leaving Chang'an, Li Shimin also received the news, and he couldn't help but feel a little apprehensive in the depths of his eyes.

"This time, the father doesn't know why he went to Guanwai"

Li Shimin muttered softly, knowing that after returning to the palace a few days ago, this emperor began to think about this question.

After all, if you don't go early or late, you will not go until after winter, even Li Shimin is very puzzled.

"Is there something that can't happen this time?"

Li Shimin's eyes couldn't help shrinking slightly, and he thought silently, after all, this father has unpredictable abilities.

Even he had to pay attention to it, and after thinking about it, he couldn't sit still.

It's just that now he doesn't seem to be able to do anything, and after his father went to the border, this emperor couldn't help but have some thoughts in his heart.

"If it goes well, then is it possible for me to drive the expedition in person?"

At this time, Li Shimin can be said to be full of thoughts, of course, Shu An doesn't know all this.

Even Shu An didn't expect that his actions would bring so much trouble to Li Shimin.

At the same time, in the border town area, Xue Rengui, who had set off one step earlier, had already arrived here, of course, Xue Rengui had a lot of emotion here.

"I didn't expect to be back here again in less than a year."

Xue Rengui thought silently, you must know that the last time he first came here, he was very worried, but now he is calm.

"yes!"

Qin Huaiyu on the side also spoke up, and his words were also full of emotion, last time they almost died in the grassland.

If it weren't for Brother Xue making the right decision, even Qin Huaiyu wouldn't dare to imagine what would happen to him.

With the establishment of the new army, Xue Rengui also transferred his team to the next level, even the previous personal guards were temporarily arranged to take an official position.

After all, there are as many as 30,000 elite soldiers in this one, and the structure and other aspects need to be handled by Xue Rengui.

In addition to Qin Huaiyu, there are also many noble sons and daughters around, and these people are the second generation who have entered the new army.

At this time, the face of the one was serious, obviously not calm in his heart, but Xue Rengui didn't care, because when they came here, it was not the same.

As long as they have experienced a war, then they will naturally grow, and of course it is not known who will fall.
