Originally, I just wanted to hear how Li Yuanjing and they discussed the problem, but this hearing scared Li Shimin a lot.

Who is Li Yuanjing?

King Zhao of the Tang Dynasty!

His younger brother Li Shimin!

And he can be regarded as half of the prince's teacher!

Datang can have such a grand occasion today, and most of the credit is due to Li Yuanjing.

In public, even Li Shimin would not use that tone to talk to Li Yuanjing.

It's not that you don't dare, but you need to consider the impact.

Once Li Shimin's attitude changes, then in the eyes of the outside world, this is likely to be a manifestation of unloading and killing donkeys.

But Li Shimin never thought that even the things he needed to pay attention to, these lowly craftsmen dared to do it blatantly.

"That's how you come into contact with them?" Li Shimin said with a deep face.

If Li Yuanjing can't give him a satisfactory answer today, he, Li Shimin, will kill them all regardless of the use of your craftsmen!

The majesty of the royal family is inviolable, and in Li Shimin's view, this is not an act of being close to the ground, but an act of excessive consumption of royal status.

This kind of thing must not happen, otherwise, over time, others will not take your royal family seriously.

"That's right, this is called rule by man, when discussing technology, everyone's identity is the same, you can say whatever you want, everything is based on the truth." Li Yuanjing smiled and nodded.

continued: "It's like the imperial history can be heard, and they don't need to investigate in too much detail, this is their duty." It is also their duty for officials to speak and do things on the basis of their words.

If the official speaks, the representative may become the decision of the imperial court, and the words spoken by the imperial history will have to be investigated in detail later.

It's the same here, a lot of things are just a word from you, no one knows when, who, what kind of seemingly nonsensical words can solve a problem that has plagued everyone for years.

Therefore, the subordinate brother set this rule here, during the technical seminar, no one should prevent anyone's right to speak, and no one should retaliate after the fact for anyone's speech.

After all these years of training, the atmosphere here has gradually become this straightforward style, in fact, this is the real academic atmosphere in the hearts of the younger brothers.

Everyone's time is relatively tight, if there is a problem, say the problem, if there is no problem, listen, it is better than not to say a certain brother, the elder brother is not talented, and the hard meditation for several days will not be fruitful, so I take the liberty to ask something or something.

Everyone is here to improve their skills, and no one wants to listen to such non-nutritious words in a limited amount of time. But after leaving this meeting, what should be done or what should be done, the rules still have to be discussed. ”

Li Yuanjing is very glad that his identity as the king of Zhao is precisely because of this identity that he is qualified to make these decisions and let everyone abide by the rules he has made.

In his view, academic conferences are just a place to do business, not to pull you around.

Of course, if you want to do these things, you don't have any objections, just play by yourself in private.

As for equality for all, this is just a beautiful ideal, but in fact it is impossible to achieve it at all.

Even if Li Yuanjing is present, it will not work, and each meeting must be presided over by several bigwigs with transcendent status, so these people will unconsciously become the center, but this is a good thing.

"What a rule for people!" Although Li Shimin didn't want to admit it, he still had to admit that Li Yuanjing was right.

However, Li Shimin does not intend to talk too much about this issue.

Li Yuanjing's reply left him speechless!

"How many of those steel ships are you going to build?" Li Shimin asked.

"If nothing else, all the next military ships will be steel structures!" Li Yuanjing said without hesitation.

"Datang can't support such a big consumption!" Li Shimin shook his head directly.

The Tang Emperor didn't talk about it, and now he also knew that it was an experiment, but fortunately, the experiment was also very powerful, and Li Shimin accepted it when he felt that he had accepted it.

The tonnage of the newly built battleship is twice as small as that of the Tang Emperor, but twice as small is a battleship weighing nearly 50,000 stones and weighing 2,500 tons.

What is the concept of 2,500 tons of steel?

Even though Datang is now full of blast furnace ironworks, according to the statistics of the Ministry of Industry, as of this year, the annual steel output of the entire Datang is only more than 7,000 tons.

That is to say, when the Tang Emperor was built, Li Yuanjing took all the production capacity from these iron-smelting mills in the east within a year and a half.

This also directly led to the slow progress of the promotion of agricultural tools in the entire east, and with the completion of the Tang Emperor, new warships were launched.

Fortunately, the tonnage was smaller, so that these iron-smelting workshops had a chance to take a breath and take the opportunity to promote some iron farming tools.

"You can take your time, but the steel battleship is a must, the next battleship specifications will continue to shrink, the one currently under construction is about 2,500 tons to 3,000 tons, in the future, it should be the flagship of a fleet, as for the rest, with four 1,000-ton warships, four 500-ton small ships, and a supply ship with a tonnage to be determined.

Not counting supply ships, the tonnage of a fleet is about 9,000 to 10,000 tons, with more than nine combat ships and one supply ship.

In the future, a fleet can be deployed in the northern Jiaodong region, which can directly deter the entire peninsula and other northeastern local waters, Lingnan deploys a fleet to be responsible for the southern and other regions, and Jiangsu and Zhejiang regions deploy a fleet responsible for the eastern seas.

As for the production capacity, let the machinery workshop work overtime, and use steam power is almost the same, if all the steam engines are replaced, the efficiency should be more than ten times the current one, and these things are not in a hurry, just do it a little bit. Li Yuanjing said directly.

Li Yuanjing knows the importance of steel for a country, but it is one thing to know.

I won't know how important it is until it really happens to me.

Now he has empty ideas, but he doesn't have enough steel to support them.

Pooling all of Datang's steel production capacity would allow him to build a fleet a year, but the question is, won't Datang's other industries develop?

If nothing else, the army can't stand it.

Without the replenishment of steel, what will happen to the loss of weapons in the army?

In fact, the military reform also allowed the imperial court to use a lot of steel in the casting of weapons, although the iron ore used some machinery, but in recent years the imperial court still tried every means to increase steel production capacity.

And the biggest problem now is not that the smelting capacity is not enough, and ten blast furnaces are not enough to be built, which is not a problem for Datang.

The real problem is that the amount of ore is not enough, and this is the most painful.
