"Uh....."

Li Zexuan was stunned for a while, and then said strangely: "Why is this? Does Chang'an City still have surplus iron ore?"

When he heard Uncle Fu say that he couldn't buy iron, he subconsciously thought that iron ore couldn't be bought either, but after hearing Uncle Fu say that, it was obviously not the case!

Fu Bo said as a matter of course: "Master, isn't this normal? There are only so many houses in Chang'an City that can smelt iron. How can they consume so much iron ore? Naturally, there is a surplus!"

China started iron smelting around the Spring and Autumn Period. Due to the rich experience in smelting bronze at that time, the progress was rapid, and pig iron and "block iron making" appeared almost simultaneously. The smelting temperature of block iron is low, the inclusions are many, but the carbon content is low, close to wrought iron, the melting point is high, the texture is soft, and it is suitable for forging utensils; the smelting temperature of pig iron is high, the content of sulfur and phosphorus 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 techniques have been comprehensively developed, and they have become technically finalized. For example, the steel-making technology is not often used due to its low efficiency. As an early form of the steel pouring process, the rule of iron has been widely used.

The iron smelting technology in the Sui and Tang dynasties continued to develop on the previous road without major breakthroughs. The main reason was to use the "steel filling method" at the end of the Han Dynasty. The smelting efficiency was not high, and the iron smelting business in this era was owned by the state. There are very few people like Changsun Wuji who can mine and smelt iron privately, so the productivity of the private sector cannot be released, and the iron smelting speed naturally cannot keep up with the mining speed!

Li Zexuan rolled his eyes secretly, thinking that he was at a loss. If I had known about this earlier, I would have waited until now?

"Oh! That's all! Since it's already like this, it's not less than ten days and a half months! When the iron smelting equipment is built in the workshop, 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 the only way! If the young master has nothing else to do, then the old man will go back to the workshop first!"

Uncle Fu heard Li Zexuan's confidence in the second half of his sentence, couldn't help but smiled, and then said goodbye.

"Well! Uncle Fu, you also have to pay attention to your body. If you have something to do, you can tell the people below to do it! Don't be tired!"

Li Zexuan said with concern.

To be honest, Fu Bo was so old and he was still busy, and he felt very sorry. But at present, he really has no one who can replace Forber! Fu Bin may be able to do it in the future, but he is still too young to be a big boss! If possible, he really hoped that Fu Bo would live a hundred years and a thousand years!

"Haha! Young master, don't worry, the old man is in good health!"

After Fu Bo said that, he went out.

…………………………

"Your Majesty, the Marquis of Yongan asks to see you!"

In the afternoon, in Ganlu Hall, Li Er was busy reading the memorial. It was the end of the year, and there were always a lot of things. He had been busy until late at night for many consecutive days! Compared with Li Zexuan, who is free and easy, he, the emperor, seems to be more hard-working. At this moment, the servant of the Huangmen outside the hall came in and bowed to report.

"Well, let him in!"

Li held the red pen in his second hand and said without raising his head.

"promise!"

After a while, Li Zexuan stepped in from outside the hall, bowed his hands in a polite manner, and said, "My minister, see Your Majesty!"

"No gift, what's the matter?"

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

Li Zexuan inexplicably felt choked for a while, and after a pause, he replied, "Go back to Your Majesty, the iron ore you asked your minister to find has now been found. It is located near Huojia Village, Yifang County. Your Majesty directly sent someone to receive it. That's it!"

Li Er heard the words and finally raised his head, "Oh? So fast? It seems that your ability to find mines is quite effective!"

Aren't ordinary people looking for iron ore for three years and five years? There is no one like Li Zexuan who has found five ore veins in more than a month. Now this product is a real family with mines!

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

Li Erhui's eyes were like torches, and one sentence hit the key point, said.

This is what Lao Li knows to ask! Li Zexuan didn't believe that Li Erhui didn't know the news. After all, what Baiqi "spy agency" is not a vegetarian!

"Uh... The people sent by the minister found a total of two iron mines, two sulfur mines, and one coal mine! Your Majesty said earlier that only iron ore was needed, so the other mine ministers didn't say anything just now!"

The implication is that, Lao Li, as the ruler of a country, you can count on your words!

How could Li Er not be able to see Li Zexuan's beautiful bowels? He said angrily: "Stinky boy! Could it be that I will go back on my word?"

"How can you do it! Your Majesty is wise and holy, even if all the people in the world go back on their word, your Majesty will definitely not!"

Li Zexuan gave a flattery with a smile.

Li Er snorted and said, "Don't wear a high hat to me! By the way, where is the other iron ore you found?"

Li Zexuan frowned slightly, then stretched it out again without a trace, and he replied, "Your Majesty, another iron mine is also in Yifang County, but it is about 20 miles away from Huojia Village, which is located in Yifang County. Near Peach Blossom Village!”

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

Li Zexuan secretly scolded Li Er for being an old fox, but he said: "Your Majesty! How can you say such a thing? According to the officials.

Those who went there reported that the two iron mines were indistinguishable from the outside. As for what was going on inside, the minister had no idea! "

That being said, the actual situation is roughly similar to this, but well, when the goods came, I compared the map and recalled the distribution map of mineral resources in the previous life, and found that the iron ore near Taohua Village is bigger than Huojia Village. Iron ore reserves are 30% higher!

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

Li Er gave Li Zexuan a suspicious look. Although what Li Zexuan said was similar to the information he had obtained, he couldn't help but suspect that there was a ghost in it! After all, Li Zexuan is too clever! If you are not careful, you will be deceived by him!

"I'll just trust you!"

Anyway, there are too many ores, and the refining will not be finished by then!

After a while, Li Er sighed helplessly and said, "In the next few days, I will let the Ministry of Industry go to mine! If you have nothing else to do, go and do it yourself!"

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

Li Zexuan didn't like to stay here at first, so he said goodbye readily: "Your Majesty Shengming! I have something to do in the academy, so I will leave first!"

After all, seeing Li Er nodding in agreement, he hurriedly turned around and walked away!
