On this day, the team did not travel again, and in order to take care of the wounded, they found a place and prepared to rest for the night, recuperate, and then continue the journey tomorrow.

After the black soil was settled, he asked Dashi where he was going next.

Dashi said with great certainty: "It's almost there, we all know this place, and we passed by it not long after we ran for our lives." Two or three more days of walking will lead to the cave. ”

"Really? Are you all sure? Hei Tu asked hurriedly.

They all nodded their heads, indicating that they all remembered the place, there was a slope there, and they had slid down the slope in a panic, and then ran in a random direction.

After confirming it again and again, Heitu was excited and immediately shared the good news with everyone.

Lin Yan's depressed mood was swept away, and if nothing else, he would soon be able to find hematite.

Everyone was in a state of great spirits, and they slept restlessly during the night's rest, hoping that the day would soon dawn and that they would immediately go to hematite.

Sure enough, they all remembered the next road and boulder, and they walked a lot along the way.

It's no longer a jungle that needs specialized people to open the way.

After walking for three days, they finally arrived at the cave where Oishi and the others once lived.

Lin Yan looked up, this is a low stone mountain, less than three hundred meters high, the grass and trees on it are sparse, not far away is the mountains, this is out of the plain.

At the foot of the mountain, there is a large forest belt, and there is also a small river running through it.

She entered the Science and Technology Museum, looked at the route map recorded by Fat Bao, and turned around all the way, and finally walked to the northwest direction of Sun City.

The distance between the two places in a straight line was uncertain, but the route they had traveled was more than 400 miles, and it took them twenty-three days to arrive.

Along the way, Lin Yan's contribution value has accumulated more than 2,000, and she opened room number 0106 to teach pen and ink knowledge.

She opened the next 0107, and there was a room full of books about the basics of herbs and pharmacology.

Lin Yan was overjoyed, no matter which room the knowledge was, it was what she needed at the moment.

When they arrived at the foot of the mountain, seeing that the cave was imminent, no one could help it, and they wanted to see the ore they had been looking for for so many days immediately.

Hei Tu ordered to stop on the spot, "One to five teams are on guard at the bottom of the mountain, the wounded stay, and the others go up." ”

The road up the mountain was not covered by grass and trees, and they used to walk on the big rocks, and they stepped out of a road, but it was not difficult to walk.

Ten minutes later, caves appeared in front of me.

Oishi said that it was the cave where their people used to live.

Lin Yan looked carefully, some of them were naturally formed, and some of them had traces of artificial excavation, and the size was different.

She picked the nearest cave and walked in.

The cave is short, more than a meter high, and contains traces of human life, bones, animal skins, leaves, etc.

Lin Yan is less than a meter tall and can stand up straight and walk inside. After taking one look, she went straight to the cave wall, where there happened to be a reddish-brown patch.

The color is not as good as the one in Dashi's hand, but Lin Yan can see at a glance that it is indeed hematite, and the purity is not high.

In order to be safe, she asked Fat Bao to help test it, and confirmed that it was hematite, with a purity of only 60%, no wonder the color was not pure enough.

Lin Yan said excitedly: "It's hematite, we found it." ”

The blue star cat that followed her walked into the cave with difficulty, and looked at the stone that Lin Yan was touching seriously, "This is hematite?" ”

"Yes, yes, seeing a stone of this color on the stone wall is the ore we are looking for."

Lan Xing reached out and touched it, then looked at the rest of the cave wall, and pointed over, "There is another piece there, darker than this color." ”

Lin Yan looked over and turned out to be on top, "That's the ore." ”

After calming down her excitement, she said, "Let's go, let's go to the other caves and have a look." If there were, this would be the mine. ”

I went around five or six caves in a row, and there were sporadic ore in them.

Hei Tu came to Lin Yan, "Dashi said that there is a big cave, and the stones in it are the darkest and the most, do you want to go and see it." ”

"Of course you have to see it, let's go, take me there."

The big cave was on the other side of the mountainside, and the big stone led them all the way through, the entrance to the cave was not big, but the space inside was very large.

With a height of more than two meters and a capacity for more than a dozen people, it is indeed a large cave.

At a glance, the color of the cave wall extending inward is getting darker and darker, and it is all ore.

"This is it, we found it, we finally found it." Lin Yan was so excited that he couldn't express it, and the iron ore in his heart was right in front of him.

She walked over and looked at the ground, there were small pieces of iron ore that had fallen, and there were quite a few of them, and she was about to pick them up immediately.

Seeing Lin Yan's movements, Hei Tu took her out and persuaded her: "I found the iron ore, and we will mine the rest, you go down and rest." ”

She's small and short, and mining is really useless, and her staying here will affect their efficiency.

Lin Yan didn't insist, just make sure it was iron ore, the thing was right in front of him, and he was afraid that he wouldn't be able to take it away.

Black Earth immediately began to arrange manpower, and everyone immediately took action.

Hua Hong took Lin Yan at the foot of the mountain, waiting for someone to carry the iron ore down the mountain.

The baskets they brought with them made a big difference, and they couldn't have been better for transporting ore. Especially those small pieces, it is most convenient to carry them in a basket.

It was too difficult to mine the ore from the stone wall, and there was no tool to take advantage of, so you had to pick up the small pieces of ore that fell first.

Hei Tu was very distressed about this, and tried many methods without success, so he could only come to Lin Yan for advice.

Lin Yan asked Heitu to find someone to collect firewood and set up a fire to boil water. Bring the water to a boil and pour it over the stone wall, repeating this way to make the stone wall crunchy.

Then he took some large pieces of ore, put them in the fire, and began to burn them, and after a while, they took them out and beat them with the ores.

The only way to dig ore out of a stone wall is to use a harder tool.

After two days of such busyness, she finally hammered out a few hard and rough utensils, with a sharp iron chisel and a hammer (just an iron lump), and she asked Heitu to take the tools to chisel the stone wall poured with hot water, and it was indeed much easier.

The chisel is aimed at the stone wall, and a few times with an iron hammer will chisel down the hard stone wall.

The others followed suit and made a lot of chisels and hammers in three days.

The ore was relatively heavy, and because of the long distance, the amount that each person could bring was limited, and after eight days of mining, each team's baskets and sacks were almost full, and they could not take any more.

Looking at the mine, everyone was reluctant, and after seeing the role of the iron chisel and hammer made from the ore, no one was willing to leave. But their ability was limited and they had to set off for the journey.

Most of the tools and clay pots for digging ore were left behind, which were later used for mining, and it was useless to bring them back.

It took ten days before leaving, and each of them made himself an iron rod with spikes out of iron ore. Although it is shoddy and does not look good, it is a sharp weapon, much stronger than the wooden sticks they use, etc., and it can be used to kill fierce beasts on the way back.

It's been nearly two months, and it will take a lot of time to go back, and it will take three or four months to go back and forth.

It was too long, and they had to return for fear that the people at home would be worried.

When we came, everyone traveled lightly, and went back to carry each load, which was a lot slower.

The black soil made the teams take turns to replace the ore, and the expedition team struggled back.
