Shu Mansion, since he threw the matter to Xue Rengui, Shu An had a few days of rest, and since Xiuning returned to Taiyuan, this courtyard has been deserted.

But this Taiyuan still has to go back, after all, Xiuning is still a loving and righteous person, which is inseparable from his teaching since childhood.

In terms of treating his subordinates, Li Xiuning can be said to be better than Li Shimin, I don't know how many times, so as early as before the Mid-Autumn Festival, Li Xiuning returned to Taiyuan to visit the guards who followed him before.

You must know that before Li Tang entered Chang'an, the place of origin was in Taiyuan, and for the same reason, there were many families who died because of disability or for Li Tang.

For most people, Li Xiu would rather not care about it, but because of her family who died in war or was disabled, she couldn't ignore it.

It was precisely for this reason that Shu An was idle for a long time, but then shook his head.

With his research on gunpowder, he didn't have much free time to accompany this disciple to leisurely.

"I don't know how long it will take"

Shu An couldn't help but murmur softly, obviously less patient, to know that in the past, if he studied the same thing, he didn't feel like this.

There is some urgency now, and the reason is also very simple, that is, he is not young.

On the other hand, Datang is estimated to be fighting, whether it is in the north or in the south, these need to be filled with human lives.

Even Shu An has a lot of sighs about this, because every time there is a war, I don't know how many families will be destroyed.

Of course, this is not to say that war is not possible, after all, if you go to war now, it will lay the foundation for future generations, and it will be worth it in the long run.

If you can get gunpowder out in advance, then you can completely reduce the loss of personnel, and in the era of cold weapons, gunpowder can be said to be an insoluble existence.

"Master, Commander Li is here!"

However, just as Shu An's thoughts were flying, Laifu's voice sounded in Shu An's ears, allowing Shu An to recover from his thoughts.

"What is the matter with Jun Xian coming to Shufu?"

Shu An's gaze couldn't help but fall on the leader of the hundred horsemen who was following Laifu and said loudly.

Needless to say, Shu An's first thought was that Li Shimin had something to find him, and when he thought of Xue Rengui's entry into the palace before, he had some guesses for a while.

Sure enough, Shu An's doubts didn't last long, and Li Junxian told the matter again, even when he first started this matter, he was a lot surprised.

I didn't expect His Majesty to send troops to the grassland, it can be said that this time it was very sudden, and there was not even any warning.

To know that Li Junxian should be regarded as a military general, he still has a lot of interest in war.

However, the key to whether to start the grassland battle this time is likely to be in the hands of this An Xuangong.

Because he knew that His Majesty came to ask this An Xuangong because of the hesitation of the imperial study.

Although Shu An had already guessed, he still made a thoughtful look on his face.

The reason is very simple, that is, it is estimated that the people in the palace do not know who proposed it this time.

It is obvious that Xue Rengui did not confess him, but it can be regarded as Xue Rengui has some thoughts.

Knowing that the person who proposed this time must be under a lot of pressure, so I don't want to implicate my teacher.

On the other side, Li Junxian watched An Xuangong fall into thought, and he was also not in a hurry.

Because His Majesty had already instructed before he came, he must accurately confirm the answer in An Xuangong's mouth.

"Ming Ze, bring pen and paper!"

After a long time, Shu An's eyes flashed with a glimmer of light.

Wu Shun, who had been standing behind Shu An, did not hesitate and immediately went to get the pen and paper.

It didn't take long for the pen and paper to be placed in front of Shu An, and this time Shu An began to study the ink alone.

Of course, Li Junxian thought that this An Xuangong was thinking, but on the facts, Shu An had already made a decision.

So at this time, Shu An remembered some other things, that is, whether to let the students of the academy intervene this time.

After all, these people have been taught by Su Lie and many guards, and some of them are not weaker than those soldiers in terms of strength.

But the more I thought about it, the more Shu An denied his idea in the end, for a very simple reason.

That is, he can't afford to gamble, after all, the identities of these people are not simple.

But soon, a student figure appeared in Shu An's mind.

Other students may not be able to, but this one student may be able to give it a try.

The student's name was Zhang Shenggen, and he was born in a family of farmers.

Originally, it was said that the academy did not consider recruiting this student at the beginning, because this student was a bit stupid.

But in the end, because of the special reasons, it was included in the portal of the college.

However, because of qualifications, even this Zhang Shenggen spent a lot of effort to become literate.

However, Confucianism and other aspects are still far from enough, but fortunately, there is a good progress in terms of military generals.

Because of the strength of the farmer, coupled with the teaching of Su Lie and others for a few months, he can be regarded as a fierce general.

This student is also an adult, and it can be said that he is about to enter the peak of his life.

You must know that this person's path has already limited the path of a general, but it is still too slow to get ahead normally.

Even if Li Shimin had a martial arts examination under his suggestion, there are many strange people in the world.

It is not so easy for Zhang Shenggen to enter the department, and the most important thing about this Zhang Shenggen is that he has a good talent in terms of strategy.

Shu An's thoughts flew and Li Junxian on the side had some wry smiles, of course, Li Junxian didn't dare to have any dissatisfaction in the face of this An Xuangong.

It's just that Li Junxian hesitated, whether to remind An Xuangong that it had been a little long.

I saw An Xuangong in front of me suddenly put pen to paper, and the master-level words made people feel pleasing to the eye.

"Take this pair back to the people, that's my answer."

But before Li Junxian's eyes could change much, Shu An's voice sounded.

Then this piece of paper has been covered, which makes Li Junxian a little depressed, because he has only seen half of the content.

Of course, Li Junxian didn't dare to be dissatisfied, but hurriedly took these words and returned them.

You must know that there has been a lot of delay in Shufu, and even Li Junxian has some apprehension.

At this time, there was not only one person waiting for him in the palace, so Li Junxian did not dare to hesitate.

Watching Li Junxian's departure, Shu An's eyes revealed a trace of confusion, and he seemed to have a lot of thoughts.

At the same time, Li Shimin's face in the court was a little anxious, of course, the same was true of the eldest grandson Wuji and others, but Xue Rengui had no words.
