"Okay, no problem, I just promised you, of course I won't go back on your word." Li Ji listened to Wang Dazhui's words, was in a good mood, and immediately agreed.

Huang Qiqi saw that Li Jidu came out, and as a subordinate, he couldn't hide inside, so he also came out to greet Jin Hu and the others, and told them to work hard with Wang Dazhu.

"The subordinates have seen the chief!" Seeing Huang Qiqi, Jin Hu and the others were really embarrassed for a while.

From everyone's expressions, Huang Qiqi naturally saw it at a glance, and said with a smile: "Don't be embarrassed, follow Wang Xiannan to do it, and it is also a contribution to the imperial court, but there is one thing that everyone must remember, that is, the Foundry Division will always be your maiden home, even if you fail in the experiment in the future, you can come back here at any time." ”

Huang Qiqi's kung fu of buying people's hearts is really perfect, and when he said a few words, he immediately made the sixteen men's eyes red, and some of them even had tears.

"Thank you, Director Huang, these subordinates of yours have come to me, I will treat them like brothers, and I will never let them suffer any grievances." Wang Dazhui thought to himself, since you can buy people's hearts, then I can too, so he swore on the spot.

Not to mention, Wang Dazhui's words had a particularly good effect, and immediately made sixteen men, including Jin Hu, feel warm in their hearts, moved by special products, and their impression of Wang Dazhui became better.

……

Since the foundry department of the imperial court is unwilling to provide iron ore raw materials, Wang Da Hammer has no choice but to carry forward the great style of self-reliance and hard work.

To find iron ore raw materials, we must first know where there is iron ore, and it must be iron ore that is easy to mine under the current technology, otherwise, if it is the kind of iron ore that is hundreds or even thousands of meters underground, it can only be a dry stare when it is found.

Finding iron ore is not easy for others, but it is not a problem for Wang Da Hammer at all.

Because he knows very well that Shanxi is very rich in mineral resources, not only rich in iron ore, but also in coal mines.

As long as you go to it in person and let the system go out to inspect it, you can directly start mining where it is easy to mine. It happens that raw materials and fuel are solved together, killing two birds with one stone.

After Wang Dazhui thought of a good place, he immediately entered the palace to find Li Shimin, if he wanted to open a mine without Li Shimin's support, he would go to Shanxi by himself and don't think about it.

Because Shanxi is facing Jinzhou at this time, it is the northern capital of the Tang Dynasty, and it can also be said to be the land of the Li family's Longxing.

Besides, iron ore was originally a strategic resource of the imperial court, and it was basically mined by the imperial court.

As early as the reign of Duke Huan of Qi, in order to help Qi develop its economy, Guan Zhong proposed the policy of "salt and iron monopoly", which brought the right to mine iron ore and buy and sell salt back to the central government.

Humans have been using iron products for at least 5,000 years, starting with the use of natural iron from iron meteorites to make iron tools.

In fact, the people of the Shang Dynasty in China have mastered a certain level of forging technology and understanding of iron, are familiar with the processing properties of iron, and understand the difference between iron and bronze in nature. However, at that time, people did not use iron ore to make iron, and iron meteorites were rare, so iron products at that time were very valuable.

"Your Majesty, the king of ministers and kings has come to greet you, I wish you great happiness and a smile on your face." As soon as he met, Wang Da Hammer first gave Li Shimin a hard slap.

"Okay, you kid can still think of coming to the palace to see me, I am already very content." Li Shimin was also very happy to see Wang Dazhui, and he was still very useful to listen to Wang Dazhui's words.

"Your Majesty, I have brought you a jar of excellent wine, you must taste it today." Wang Dazhui said as he put a jar of wine he brought in front of Li Shimin.

"Wang Xiannan, you are sending things and slapping on the back, is there anything you want me to help with?" Li Shimin asked.

"Your Majesty, where do you want to go? It's been a long time since I've seen you, so I brought a gift to see you. Wang Dazhui said as he opened the wine jar and poured a bowl of wine for Li Shimin.

As soon as the wine jar is opened, a fresh fragrance immediately wafts out, and the faint fragrance comes to the nose, and the smell makes people feel special enjoyment.

"What kind of wine is this? It's so fragrant? Li Shimin asked in surprise.

The wine in the bowl is clear and sweet, and you can clearly see the reflection inside. It's like clear water.

Li Shimin couldn't wait to pick up the bowl and taste it, and immediately felt that the aroma was rich, soft and sweet, the fragrance was harmonious, and the tail was long.

The wine brought by Wang Dazhui was brewed when he was empty, and it tasted a bit like Wuliangye in later generations. The liquor with strong flavor is fermented and brewed with glutinous sorghum as raw material.

"Good wine! It's a rare wine! Li Shimin took the bowl and drank it all, and immediately praised it.

"Your Majesty is still satisfied, right? This is the liquor I specially brewed from glutinous sorghum in Sichuan, the quantity is limited, and I specially brought a jar for Your Majesty to taste first. Wang Dazhui explained while pouring wine for Li Shimin like a shopkeeper.

"It's rare that you are so hearted, for the sake of this jar of wine, as long as your request today is not excessive, I can agree to you." Li Shimin reminisced about the aroma of the wine, and his face was full of red light, as if he had drunk immortal wine.

After listening to Li Shimin's words, Wang Dazhui's heart was very happy, and he thought to himself, I will wait for your words.

"Your Majesty, the minister has a way to improve steel smelting, which was originally intended to be provided to the Foundry Division, but because they were worried that the minister's method would not work, they asked the minister to find iron ore raw materials to test by himself, and the minister had no choice, so he had to come to His Majesty to think of a way." Wang Dazhui saw that the time was ripe, so he told his intentions.

"You're talking about the blast furnace iron-making method you mentioned, right? General Li Ji has already mentioned this matter to me, and since General Li Ji has refused to let you directly use the iron ore of the Casting Division, I have no choice. Li Shimin also thought that Wang Dazhui wanted to ask him to come forward and ask for iron ore directly from the foundry department, so he planned to refuse.

As an emperor, he understands better than others the hard-won raw materials of iron ore. It really can't afford any waste.

Because the ancient mineral mining technology was particularly backward, the earliest ancients used the open-pit reclamation method to plough the land with iron ore, so that the ore was exposed to the ground. "Tiangong Kaiwu" records: soil ingot iron (i.e., limonite nodules) "shallow floating soil surface, no deep holes", "if smelting and frying, floating people pick it up. And when it had rained, the oxen ploughed the soil, and gathered up a few inches of it." It can be speculated that this is the earliest way to discover iron ore underground.

Such a method is undoubtedly difficult to mine the ore that is buried deeply. Only some shallowly buried or even open-pit iron ore can be found.
