After Li Tai on the side finished speaking, his eyes couldn't help but show a hint of expectation, as if he wanted to know his father.

It's just that what disappointed him was that although his father looked thoughtful, Li Tai still couldn't see through this father.

Of course, this is for sure, after all, Li Shimin is the emperor of the Tang Dynasty after all, how can it be possible for Li Tai, who is still underage, to see through it.

Although he thought that the method was feasible, Li Shimin did not say anything immediately, nor did he give this son any extra surprises.

In addition, Li Shimin still recognizes Li Tai's growth, at least among his heirs, no one can be like Li Tai.

After thinking of this, Li Shimin's eyes dimmed slightly, but his voice still sounded slowly.

"Qingque's method is good, but my father still needs to think."

"In addition, your mother also misses you a little, remember to go."

.....

At this time, Li Shimin was like a loving father in an ordinary people's home, showing rare warmth, of course, this was only limited to a few people.

"Yes, Father!"

Li Tai spoke out without any hesitation, with a hint of longing in his words.

After all, he is just a child, if it weren't for Grandpa An's teachings and thinking of his identity, Li Tai would not be able to calm down in his heart.

The words between father and son unconsciously passed a lot of time, and not long after Li Tai left, Li Shimin began to worry about the eldest grandson Wuji and others.

Li Shimin may not have cared about the people before, but now his words are also concerned with his son's words.

"No one should starve to death in my Datang!"

Li Shimin's eyes flickered and he thought silently, you must know that the population of Datang has dropped to a certain number.

After all, the successive years of conquest have killed many people, and the population represents more soldiers, even Li Shimin has to be sad.

.......

The news of Li Tai's return also spread to Shu Mansion, and Shu An's face showed a lot of interest.

"I guess I think I have a lot of feelings."

Shu An muttered softly, although he arranged for Li Tai to be guarded, he was not like Li Shimin.

I can send back the news through the hundred horses every day, so I can only guess roughly.

Xiuning hasn't come here today, presumably because she knows this news, she should have entered the palace.

Of course, Shu An didn't care about this matter, but at this moment, a noisy voice came.

"You don't have to do laundry for the master, you don't have to cook, you just need to take care of ordinary daily life."

Laifu's voice sounded, as if he was teaching something, and as for who to teach, then naturally there is no need to say more.

It's just a little girl who has just entered the house, and in fact, there are not many things in the house that need more than a little girl.

Usually, some clothes cleaning is done by recruiting some long-term workers, but in fact, this is a chance for some people.

However, Laifu usually did a lot of things for Shu'an, so Laifu divided part of his affairs to this little girl.

Of course, there is not much to do, and it can be said that it is very easy.

For a while, this little girl was a little stunned, because this seemed to be different from what her mother taught.

Thinking of this, she couldn't help but nod her head, because she knew that it would be good to remember the words of this butler.

The noise didn't last long, and there was a little follower next to Shu An, but fortunately he didn't care.

is still thinking about his own affairs, but in fact, Shu An at this time is thinking about something that can get this era.

At this time, one of Shu An's most regretful things was why he was a liberal arts student.

If you are a science student, even an ordinary science student, you can have something to get into this era.

In fact, liberal arts students have also studied some physical chemistry, but those are all memories of junior high school.

By the time I got to college, I had already forgotten about it, and it was precisely because of this that Shu An had a wry smile.

After all, most of the things learned are useless, such as electricity, and in this era, there is not even electricity, let alone wiring, etc.

Shu An vaguely remembered what series and parallel knowledge points, which were of no use at all.

But when you think about it, there's something you can try.

For example, gunpowder, you must know that the earliest origin of gunpowder is alchemy, and it is unfortunate that it appeared in this era.

Among them, gunpowder was used in the military, that is, the Tang Dynasty, but Shu An's memory was the end of the Tang Dynasty.

Naturally, Shu'an couldn't wait until that time, after all, the daylily was cold at that time.

Not to mention that he still remembers some configurations of gunpowder, plus this era verification, it may not be possible to make a cannon.

Of course, this requires a lot of things, and after thinking of this, Shu An's heart can't be calm.

If there is a cannon, it can play a decisive role on the battlefield.

After thinking of this, Shu An couldn't sit still, but this matter is not so easy to say and do.

Shu An's eyes flashed with a glimmer of light, if it was for people to study, then it would naturally start with those Taoist priests.

After all, these people are the best candidates for research, if he remembers correctly, Li Shimin should have supported a lot of Taoist priests.

Li Tang finally recognized Lao Tzu, the ancestor, so it is certain to support a few Taoist priests.

However, now Li Shimin is in the period of youth and strength, so he is not obsessed with alchemy.

You must know that from ancient times to the present, this alchemy technique does not know how many emperors have been harmed.

For example, Qin Shi Huang sent Xu Fu Dongdu to seek the elixir of immortality, and for example, Emperor Wu of the Han Dynasty believed in the art of immortality very much.

The merits of these people in history do not need to be judged by Shu An at all, but these people have not escaped the art of immortality.

Of course, there may be a Li Shimin in the future, after all, according to historical records, Li Shimin just ate the pill refined by Fang Shi, so he was poisoned by heavy metals.

I don't know how Shu An is in history, but it is estimated that there are seven or eight points that can be confirmed.

"This matter may be secretly exposed, after all, these people can't die, and they are still useful."

Shu An thought silently, thinking about where to start, after all, if he talked to Li Shimin about things like cannons, he would definitely not understand.

So it's more practical to take your time in secret, and there are a lot of risks associated with artillery.

Fortunately, it is not impossible to reduce the risk, as long as the protective measures are taken.

I don't know how long time has passed, the corners of Shu An's mouth are slightly hooked, and he seems to have some thoughts.

This matter still needs to start with Li Yuan, speaking of which, he hasn't seen this old friend for some days.
