After breakfast, Li Chuan quickly waited for Li Shimin's summons.

As soon as he walked into the Chongwen Palace, Li Chuan found that in addition to Li Shimin, Li Chengqian and Wang Dehai, there were two people standing in the hall, one looked about fifty years old, and the other was younger, about twenty years old.

Neither of them was wearing official uniforms, but looking at their temperament, they were somewhat similar to those who were craftsmen and supervisors, and Li Chuan thought so because he recognized the drawings in the hands of the two of them, which was the one he gave to Li Shimin.

These two people are very serious, and they are obviously experts who can understand.

"Humph!" Li Shimin snorted coldly, looked at Li Chuan indifferently, and asked, "Why didn't you tell me earlier?" ”

Li Chuan understood what he was asking, so he replied: "It's not too late to say, if we want to develop, it will definitely have an impact on the environment, and we can only try to reduce this impact, especially to maintain good air." ”

Thinking about the haze of the later generations, Li Chuan wanted to sigh.

"If you had said it earlier, I would have made arrangements earlier." Li Shimin continued to accuse him.

Li Chuan didn't hear Li Shimin's blame, and continued: "It's not too late to arrange it now, even if it's two years later, anyway, when large-scale pollution has not yet appeared, it will be too late to pay attention to protecting the environment." ”

Li Shimin is a little angry, this guy is always sluggish when he should be sensitive, and even more sluggish when he should be dull!

Talk to him, don't say it directly, and he will hardly be able to analyze your tone and intentions.

At first, he suspected that Li Chuan was pretending to be stupid, but later found out that he was really stupid.

After getting used to it, in fact, Li Shimin also learned to regulate his emotions, just like now!

Li Chengqian's expression remained unchanged, he was used to this kind of conversation, but the two people who heard this conversation on the side were stunned, and the horror in his heart could not be expressed in words.

It's the first time I've seen such a bold official, right? Looking at the age, although they are a little younger, they are sure that this is not a royal child.

Nothing else, mainly the royal children they all knew, although those people didn't necessarily know them.

"Li Chuan Li Qianqian, you should all have heard of it." Li Shimin ignored Li Chuan, and turned to the two people: "The drawings in your hands are the ones he brought, and the generators that can't be assembled are also from him." ”

The two of them instantly widened their eyes, looking at Li Chuan's expression as if they were looking at aliens.

Li Chuan was a little uncomfortable, avoided their gaze, looked at Li Shimin, and waited for Li Shimin to introduce these two people to him.

As a result, Li Shimin shut up and stopped talking.

Li Chuan was stunned, how could anyone introduce only half of the introduction? He doesn't even know who this person is?!

Li Chengqian saw that his father really didn't want to speak, so he could only take the initiative to talk next, he couldn't embarrass everyone here, right? !

"These two are the losers of the public, and they are the people of the agency." Li Chengqian didn't say much, just pointed it out.

Li Chuan instantly remembered a sentence: The Mo family organ, the wood and stone walk, the bronze opening, want to ask the public to lose!

Where did this phrase come from? Li Chuan didn't think about it, but he knew that the loser was very powerful.

Especially in terms of weapons, it seems that the Eight Ox Crossbow was designed and manufactured by them.

Thinking of the Eight Bull Crossbow, Li Chuan muttered, but at this moment, the hall was very quiet, and everyone heard him when he made such a sound.

And they were all shocked, especially the two losers, who simply jumped up and asked, "How do you know?" ”

But after asking, after reacting, he knew that he was a little stupid, after all, everyone knew that Li Chuan was a person from a thousand years later, so it was normal for him to know some secrets that no one knew at the moment.

Compared with the two public losers, Li Shimin and Li Chengqian seem too calm.

Although they were inevitably shocked in their hearts, they didn't show it on their faces, especially when someone next to them was comparing, and their compulsion suddenly increased.

"The Eight Ox Crossbow is famous after a thousand years?" Li Shimin asked with a slight squint.

"Ah, what a great weapon, a siege weapon." Li Chuan added: "I remember that it seems to have been banned later, except for the siege of the city, it is not allowed to be used at other times, it is too powerful." ”

Li Shimin listened, his face darkened, and he said unhappily: "The weapon is used when it is manufactured, how can it be banned?" Isn't this self-defeating martial arts? Which unfilial son is it? ”

Li Chuan was silent for a moment and said, "That unfilial son will not be born until at least a few decades later." ”

So it's impossible to learn a lesson!

Li Shimin felt even more depressed, this feeling of being angry, but not being able to catch the culprit and teach a lesson was too fucked.

He could only leave a holy decree to tell those descendants what to do, but whether they were obedient or not, Li Shimin was not sure in his heart.

When the two losers heard that the Eight Bull Crossbow was disabled, their faces turned red, and they almost jumped up in disagreement.

Fortunately, Li Shimin spoke out before them, which made them barely rude in front of the king.

"The Eight Ox Crossbow has been successfully manufactured?" Li Chuan only knew that the Eight Bull Crossbow was a sharp weapon in the Tang Dynasty, but he didn't know what period it was made, was it so early? !

"Not yet, but soon." The young man replied.

As soon as he spoke, everyone turned their heads to look over, and suddenly they were young and confused, and they were a little overwhelmed and flustered.

Another middle-aged man glared at him fiercely, daring to answer anything, and sure enough, it was right not to let him out.

"Millennium, how does the cannon you mentioned before compare with the Eight Bull Crossbow?" Li Chengqian suddenly asked curiously, and his question also drew everyone's attention back.

"Cannon!" Li Chuan grinned bitterly and said, "There is no comparison." ”

"How?" Li Shimin's deep voice sounded.

"If it's compared to the bronze cannon that just appeared, I really don't know which one is more powerful, but compared to the cannon at my time, it's ...... It really can't be compared. Li Chuan was careful with his words, he didn't want to make people angry because of the inappropriate use of words.

Obviously, he didn't mean to belittle Datang, it was just an objective comparison, but it sounded like he had a feeling of disliking Datang, and he didn't know why.

Everyone understood what he meant, Li Shimin and Li Chengqian didn't react, the faces of the two losers were not very good, and the young man was still muttering something he didn't believe in what he did, he would do the best and so on.

In the end, he was kicked by the middle-aged man before he quieted down.

"I remember you said you were going to make artillery, didn't you?" Li Shimin looked at Li Chuan with half-squinted eyes.

Li Chuan laughed dryly, a little weak-hearted, "You can't blame me for this, after all, the technology can't be reached." ”

After thinking about it, he added another sentence and said: "It's okay to make copper cannons, but we don't have so much copper, and the power of copper cannons is not enough, so it's better to use the Eight Bull Crossbow." ”

"What the copper cannon can do, can the eight bull crossbows do?" Li Shimin asked.

Li Chuan thought about it very seriously, "It should be possible." "And some artillery can't do it, and the eight-bull crossbow can do it.

You must know that it is a crossbow arrow that can only be pulled apart by eight oxen, a sharp weapon for siege, and it is powerful.

The walls of this era must not be able to resist, of course, if red brick and cement are used, then it should be able to withstand it.

"Well, let's do it first." Li Shimin originally wanted Li Chuan to get another weapon out, but since it was the same, there was no need to spend vain effort.

"Your Majesty." The middle-aged man who lost the public spoke up.

As if he suddenly remembered something, Li Shimin beckoned at Li Chuan.

Li Chuan took a few steps forward, and Li Shimin ordered: "You go with them and answer their questions, they are the most clever craftsmen in the Tang Dynasty, if they can't do it, then you can give up." ”

"Master Li, we have a lot of questions we want to ask for." The middle-aged man took two steps forward very politely, standing three meters in front of Li Chuan, and said very sincerely.

"I don't necessarily know the answer." Li Chuan had a bitter face, and wanted to ask him for advice, what could he do? Self-study also takes time.

"Master Li knows more than us." The middle-aged man said a word, and followed Li Chuan out.

The young man who was left behind looked unconvinced.

In his opinion, Li Chuan is not professional at all, he is a person from the future, he knows a lot, and he can get some novel things, just in terms of level, he doesn't think that Li Chuan is better than himself at all.

If he can be born in the future, he will definitely be much stronger than Li Chuan.

Maybe he didn't need any drawings, and he could build everything that Datang needed.

Really, Gong Yihao thinks that Li Chuan is quite useless, although he is from the future, but look at what he has done? That is, to put forward some ideas, but those ideas are not his, and then point out the craftsmen, and sometimes have to find books on the spot, which is obviously the result of not working hard.

Gong Yihao actually wanted to know how Li Chuan got the things that would have been a thousand years later, if it weren't for that, he probably wouldn't have been able to do anything.

Li Chuan followed the middle-aged man all the way to a cross-courtyard next to the craftsman's prison, the area inside was not small, and there were many things, it was very messy, but there were not many people.

Compared with the craftsman supervisor next to them, there were nine-tenths fewer people here, but they all looked like they were working seriously, and few people even noticed them when they walked in.

Li Chuan has been in and out of the craftsman prison many times, but he has never noticed this small courtyard, first, because the courtyard gate is somewhat hidden, and the entrance and exit are not in the same direction as the craftsman's supervisor, but the small door specially opened at the corner.

Another is that this small courtyard is also not distinctive, unlike some yards planted with bamboo, you can see a bamboo forest from a distance, or plant flowers and various trees, and this small courtyard has nothing planted, just like a lot of office work, or a place for palace people to rest, simple and unified people are easy to ignore.

But when I came in, I realized that there was a different world here.

There are not many houses in the courtyard, and the main houses add up to a dozen rooms, but the yard is very large, and it is obviously divided into several parts.

Li Chuan looked at what those people were busy with, and he didn't see any signs, so he withdrew his gaze and followed the middle-aged man into the main room.

"Lord Li, here are all the people of our public losers, the things we study are the most secret weapons of Datang, although I know that there is no need to say this, but I still have to ask my lord not to say anything you see or hear here." After sitting down, he didn't even serve a cup of tea, and the middle-aged man said such a paragraph first.

Li Chuan didn't care, just smiled and said, "I understand, you can rest assured, if I dare to talk nonsense, Your Majesty won't be able to spare me." ”

He still pays attention to this point, and he never says anything that should be said to anyone other than Li Shimin.

Of course, in fact, he also has to thank those people for their cooperation, for example, when he first came, although he was vigilant, he was not very suitable for the situation of Datang.

If someone really wanted to talk about it at that time, maybe he would have said something.

But those people didn't dare to ask Li Chuan anything for the sake of their own lives, which gave him a transition period.

"The surname Gongyi has left a strong mark on history, and many scholars who study history will lament why the genius of Gongyi did not live in modern times, if any...... Then it's time for the world boss to change. This is very flattering, Li Chuan said this on purpose to have a good relationship with the public loser, after all, the clever craftsman helped his plan too much.

Although his plan has not yet been released!

The middle-aged man tried to strain his face, but in fact, the corners of his mouth had already curved, and his eyes were full of pride, which was confidence in his own strength.

"Datang is the number one in the world."

"That's a good thing, the current Datang is very close to the world's No. 1." Li Chuan also agrees.

"What does it mean to be very close to the number one in the world? We are number one in the world. The middle-aged man was very stubborn and bent on making Li Chuan admit this.

Li Chuan could only smile bitterly and nod again and again.

After that, the two fell silent.

Probably the middle-aged man felt that he was a little excessive, so he coughed lightly and said: "In Xia Gong Yuan, he is the current head of the family, and the young man outside is my son Gong Hao, and he may also be the next head of the family. ”

Li Chuan listened and gave a thumbs up to express his admiration, it is rare to see such a simple family.

Gong Yiyuan frowned, but he didn't ask Li Chuan about his technology, but asked first: "After a thousand years, there are no more public losers?" ”

Breaking the inheritance is a big deal, especially in a family like the public loser who inherits it with its own craftsmanship.

"Uh, this ......" Li Chuan really doesn't know, the historical public loser, he barely understands the skin, as for the modern public loser? He didn't pay attention to it at all.

After thinking about it carefully, he said: "The public loser should still be there, but the inheritance may be ...... Not so comprehensive, right? After all, after so many wars, sometimes it is so chaotic that you can't even pack your things and have to run for your life, in this case, it is normal for your family to be scattered, and in times of war, it is even more difficult to find your family. ”

He only said this, as for how the other party understands, he can't control it.
