Otaku Engineer in Great Tang Dynasty

"Uh....."

Li Zexuan was stunned, and then wondered: "Why is this? Is there any surplus iron ore in Chang'an City?"

When he heard Fubo said that iron ore could not be bought, he subconsciously thought that iron ore could not be bought, but after hearing Fubo's words, it was obviously not the case!

Fu Bo naturally said: "Master, isn't this normal? There are only so many homes in Chang'an City that can smelt iron. Where can they consume so much iron ore? Naturally, there is surplus!"

China began to smelt iron in the Spring and Autumn Period. Since there was already a wealth of experience in smelting bronze at that time, progress was rapid, and pig iron and "block iron smelting" appeared almost simultaneously. The smelting temperature of lump iron is low, there are many inclusions, but the carbon content is low, close to wrought iron, the melting point is high, the texture is soft, suitable for forging utensils; the smelting temperature of pig iron is high, the sulfur and phosphorus content is large, and the texture is hard and brittle , But wear-resistant, suitable for casting utensils.

Since the Han Dynasty, various metal smelting and processing technologies have obtained comprehensive development and tend to be technically finalized. For example, Baisteel steelmaking technology is not often used because of its low efficiency. As the early form of the steel filling process, the Sutie Law has been widely used.

The iron smelting technology in the Sui and Tang dynasties continued to develop on the previous road without much breakthrough. The main thing was to use the "steel filling method" in the late Han Dynasty. The smelting efficiency was not high, and the iron smelting business in this era was owned by the state. It is rare for Changsun Wuji to mine iron smelting privately, so the productivity of the private sector cannot be released, and the iron smelting speed can naturally not keep up with the mining speed!

Li Zexuan rolled his eyes secretly, and his heart was lost. If I had known this, would I have waited until now?

"Oh! That's it! Now that this is the case, it is not less than ten and a half months! When the workshop has completed the iron smelting equipment, the iron ore from Yifang County should almost be shipped back! Our workshop will never be short of iron again!"

Li Zexuan sighed and said helplessly.

"That's all! If there is nothing else, the young master, then the old man will return to the workshop first!"

Fubo heard Li Zexuan's self-confidence in the second half of the sentence, couldn't help but smile, and then said goodbye.

"Yeah! Fu Bo, your old man must also pay attention to your health. If you have something to ask the people below to do it! Don't get tired!"

Li Zexuan cared.

To be honest, Fu Bo is so old and busy, and he feels uncomfortable. But at present he really has no one to replace Fu Bo! Fu Bin may be able to do it in the future, but now he is still too immature to be a big responsibility! If he can, he really hopes that Fu Bo will live a hundred and a thousand years!

"Hehe! Master, don't worry, the old man is in good health!"

Fu Bo said, and went out.

"Your Majesty, see you Yonganhou!"

In the afternoon, in the Ganlu Temple, Li Erzheng was busy reading the memorials. It was until the end of the year and there were always a lot of things. He had been busy until late at night for many days! Compared with Li Zexuan, who was at ease, he, the emperor, looked even more bitter. At this moment, the attendant inside the Yellow Gate outside the hall came in and bowed to report.

"Well, let him in!"

Li secondhand held the Zhubi and said without lifting his head.

"promise!"

After a while, Li Zexuan stepped in from outside the hall and bowed his hands in a respectful salute: "Chen, see Your Majesty!"

"Exemption, what's the matter?"

Li Erxi's words were like gold, and said softly.

Li Zexuan felt choked inexplicably, he paused, and he replied: "Back to your majesty, the iron ore you asked the minister to find has been found. It is located near Huojia Village in Yifang County. Your Majesty sent someone to receive it directly. That's it!"

Li Er finally raised his head when he heard the words, "Oh? So fast? It seems that you are very good at finding mines!"

Don’t most people look for iron ore for three or five years? How can someone find five mineral veins like Li Zexuan in more than a month, now this product is a real home mine!

"Look at this, your kid has gained a lot this time! Tell me!"

Li Erhui's eyes are like torches, and he hit the key with one word, said.

Lao Li asked knowingly! Li Zexuan didn't believe that Li Erhui didn't know the news, after all, what Baiqi "secret agency" is not a vegetarian!

"Uh... the people sent by the ministers found two iron ore mines, two sulphur mines, and one coal mine! Your Majesty said earlier that only iron ore is needed, so the other miners didn't say anything just now!"

The implication is that Lao Li, as the prince of a country, your words can be counted!

What kind of person is Li Er, how can he not see Li Zexuan's colorful intestines? He didn't have a good temper: "Smelly boy! Will I turn back?"

"Where can it be! Your Majesty wise saint martial, even if all the people in the world turn back, you will certainly not!"

Li Zexuan gave a flattery with a smile.

Li Er "chicks" and said, "Don't wear a high hat for me! Where is the other iron ore that you found?"

Li Zexuan frowned slightly, and then unfolded again without a trace. He replied: "Your Majesty, another iron mine is also in Yifang County, but it is about 20 miles away from Huojia Village. Near Taohua Village!"

Li Er smiled meaningfully, and then said: "That iron ore must have more ore than this iron ore in Huojia Village, right?"

Li Zexuan secretly scolded Li Er as an old fox, but said: "Your Majesty! How can this kind of thing be accurate? According to the person sent by the minister to report it~www.ltnovel.com~ The two iron mines look no different from the outside. As for what was going on inside, the minister didn't know at all!"

That being said, the actual situation is roughly the same as this. However, when the goods arrived, I checked the map and recalled the distribution map of mineral resources in the previous life. I found that the iron ore near Taohua Village is better than Huojia Village. The reserves of iron ore are 30% higher!

That's why he handed over the iron ore in Huojia Village to Li Er!

Li Er glanced at Li Zexuan suspiciously. Although Li Zexuan said similar to the information he had obtained, he still couldn't help but suspect that there was a ghost in it! After all, Li Zexuan is too clever! If you don't pay attention, you will be deceived by him!

"I will believe you for the time being!"

Anyway, there are too many ore, and I won't be able to finish it by then!

After a while, Li Er sighed helplessly, and said: "In the next few days, I will ask the Ministry of Engineering to start mining! If you have nothing to do, go ahead and do it yourself!"

The subtext is-if you have nothing to do, you can go!

Li Zexuan didn't like staying here at first, so he happily said goodbye: "Your Majesty Shengming! The minister has something to do in the academy, so let's leave first!"

After all, seeing Li Er nodded in agreement, he quickly turned around and drove away!
