Deep in the cave, several of Guan Xiaorou's female relatives and female soldiers were chatting about the bandits just now, when they saw Jin Feng rushing in.
"Sir, although we are female soldiers, can you avoid suspicion?"
Qing Mulan said angrily.
"The head of the family..."
Guan Xiaorou was also a little bit dumbfounded.
Only then did Jin Feng see that the female soldiers had all taken off their armor, and their clothes were not even dry and were clinging tightly to their bodies.
Seeing Jin Feng come in, several thin-skinned female soldiers squatted on the ground, and one hurriedly started to put on armor.
"Sorry everyone, it's a bit urgent."
Jin Feng also knew that there was something wrong with Meng Lang, so he quickly apologized.
"What's the emergency?" Qing Mulan asked curiously, "What's the emergency?"
"Xiao'e brought me a stone and said that the cave is full of black stones. I'll come in and have a look."
Jin Feng said as he opened his palm to reveal the stone inside.
"Is there anything wrong with this stone?" Qing Mulan asked.
"Do you know why your sword is black and harder and sharper than other swords?"
Jin Feng said: "It's because of it!"
What he was holding was a piece of tungsten ore.
When he was packing up the things left by the old blacksmith, he accidentally found a few pieces of tungsten ore from the waste that the old blacksmith had not thrown away. Later, when he made a sword for Qinghuai, he tried to add some tungsten ore powder.
He reluctantly synthesized tungsten steel, and then used tungsten steel to create a black sword.
Although the tungsten steel synthesized by Jinfeng is not qualified due to limited technical conditions, the black knives produced are enough to beat all existing knives of Dakang.
The biggest feature of tungsten steel is that it is hard and wear-resistant, and it is often used to make various drill bits and cutting tools in later generations.
With drill bits made of tungsten steel, Jin Feng can consider making original hydraulic or wind machine tools, which can not only increase production speed, but also achieve preliminary precision processing.
That's why he was so excited.
But Qing Mulan was even more excited than she was.
"The black knife is made of it?"
"Yes!"
Jin Feng picked up the torch, squatted down and carefully observed the stones in the cave. He also picked up two stones and knocked them against each other a few times, then picked up another one and put it under the torch to observe carefully.
"Mu Lan, can you think of a way to help me contract this mountain?"
Jin Feng suddenly raised his head and looked at Qing Mulan.
Because he didn't like to owe favors, he rarely asked Qing Mulan for help, but this time he was moved.
Tungsten is widely distributed in nature and is found in many rocks, but the content is extremely low and cannot be smelted at all.
The stones in this cave have an obvious metallic luster, indicating that they contain very high tungsten.
Tungsten mines are usually deep underground. This kind of open-pit tungsten mine is very rare. Jin Feng wonders if he will encounter it in the future if he misses this time.
Even if I owe Qing Mulan a favor, I must get this tungsten mine!
But Qing Mulan scratched her head and asked, "Contract? What do you mean?"
"I just want to take over this mountain top and mine this kind of ore." Jin Feng explained.
"You can mine if you want, who cares about you?"
"Don't you need to report to the government and say hello?" Jin Feng asked in surprise.
"If you really want the ore from this mountain, it's best not to say hello to the government."
Qing Mulan said: "This is an ownerless barren mountain, and it is the boundary between two counties. Even if you hollow out the mountain, no one will care about you. But if you go and tell the government, what will happen to you?"
Don’t even think about it, even if the government continues to leave the mountain deserted, they won’t let you move.”
"Understood."
Jin Feng smiled bitterly and stood up.
He still has the thinking inertia of his previous life, believing that mineral veins belong to the state and cannot be mined privately by individuals.
So when he discovered the mineral vein, his first thought was to contract it from the government and then mine it.
But I forgot that in Dakang, there is no department supervising the mineral veins. Anyone who discovers them can mine them.
"But this is an official road, and there are still some traders coming and going. If you really want to mine, sir, you'd better find a way to cover it up."
Qing Mulan said: "For example, if we build a bandit stronghold nearby and tell merchants not to stay here, no one will notice."
"Miss Mu Lan, other bandits have built their strongholds in deep mountains and old forests, but you have built your stronghold next to an official road?"
Tie Zhui, who had followed him at some point, said: "This is the official road from Jinchuan to the county. Not only are merchants coming and going, but also servants. If you build a bandit village, it will cut off the connection between Jinchuan and the county. The government wants to
It won’t be possible if we don’t come to encircle and suppress them.”
"Then what do you think we should do?"
Qing Mulan asked unconvinced.
"I think it's okay to pick it secretly. When the time comes, find a few people to keep an eye on both sides. We'll stop when there are people, and we'll start when there's no one around." Tie Chui said.
"Do you know how many people it takes to mine a vein and how much commotion it will cause?"
Qing Mulan glanced at Tie Hammer: "If you don't cover it up, you can't hide it at all. It's a bad idea of yours."
"That's more reliable than building a bandit stronghold."
"You are unreliable."
The two started arguing as they talked.
"Okay, stop arguing." Jin Feng stopped the two of them with a headache: "I'll think of a solution."
"Sir, the rice is cooked. It's time to eat."
Only then did Iron Hammer remember why he came in.
"Let's go eat first."
Jin Feng took Xiao'e out.
After dinner, the heavy rain still continued, and it would be impossible to walk at night. Jin Feng asked Tie Hammer to arrange for two veterans to be on guard, while the remaining people lay on the ground in the cave.
The veterans are still outside, and the female soldiers and their families are inside.
The veterans were okay, they were all people who had endured hardships, and they fell asleep quickly.
But Jin Feng felt sad. Not to mention the hard ground of the cave, it was also bumpy and bumpy, so Xiao'e still had to stay in Jin Feng's arms.
It wasn't until midnight that Jin Feng fell asleep.
After dawn, Jin Feng woke up and felt that his legs were no longer his.
Fortunately, the rain has stopped.
While making breakfast, Iron Hammer came over and asked, "Sir, are you leaving or staying?"
"Let's go. Everyone was caught in the rain yesterday. Let's go to the county town early so we can take a shower and change clothes."
"What should I do with this cave? Should I leave my brothers to watch over it?"
"No need, no one has noticed for so long. If you stay here, it will be easier for others to notice you."
Jin Feng shook his head: "And the bandits from before might come again. It would be too dangerous to leave too few people. Let's bring more people next time."
In the previous life, tungsten ore was discovered and utilized very late. Jin Feng believed that no one in Dakang knew about tungsten ore, otherwise the old blacksmith would not have thrown those pieces of tungsten ore together with the waste residue.
After breakfast, a group of people continued to set off.
Jin Feng was thinking about bandits and tungsten mines along the way, and was not in the mood to see the scenery. The speed of the convoy accelerated a lot, and the rest of the journey went smoothly. In the afternoon, a group of people arrived at the county town smoothly.
