Lan Yue and Mao Mu were both coming to the mine for the first time, and they were curious about everything, so they pulled Lin Yan to look around with them.

"It's really ore, and it grows in the stone wall." Mao Mu reached out and touched the reddish-brown place.

"Last time, I dug up so much ore and brought it back, so there can be a fake." Lin Yan said angrily.

"Hehe, I'm not too excited. The first time I saw the original ecology of the ore, it was inevitable. ”

Lan Yue also said: "It's the first time I've seen it. This ore really grows in the stone wall, and it is hard to imagine how many years it took to form. ”

"Every original mineral is formed after precipitation, endless years, and a long process of change. It's just that with our current capabilities, we can't survey and calculate time. ”

Lin Yan regretted that in this wild place, it was too difficult to survey these.

Blue Moon and Mao Mu are both people who have gone through Lin Yan's science popularization, and they have more or less understanding of the formation of ores and the movement of the earth's crust.

Both nodded at the same time.

Lan Yue said: "It's really a pity. We have to work harder. ”

"Let's start with mining." Mao Mu took out a hammer and chisel and started digging stones.

Lin Yan and Lan Yue stood on the side and watched. It took him a long time to knock down a small piece of ore.

Mao Mu was sweating, "This is too hard, how did you dig down so much ore?" ”

"You think that's all there is to mining stones?" Blue Moon asked.

"Or else?" Mao Mu looked at the tools in his hand, "Is there any other way?" ”

Lan Xing, who happened to come in to find someone, heard this, and said with a smile: "This ore is very hard, it is difficult to chisel it from the stone wall, it needs to be poured with hot water, and it is easier to dig it again." ”

Mao Mu scratched his head, "No wonder, it's so hard, it's too difficult to mine stones." ”

"It's easier to find a way." Lan Xing looked at Lin Yan after speaking, "The black soil is looking for you." ”

"What are you looking for us?" Blue Moon was puzzled, "Didn't you just see it?" ”

"I don't know, he asked me to come to you."

As soon as he saw them, Hei Tu said: "The ore is heavy, and it will be refined when brought back, so we might as well refine it here and then bring it back and use it directly." It's worth it. ”

Mining costs a lot of time, and it's even more difficult to transport it back, and Black Soil thought about this before he came. He went to the smelter and saw that after the ore was calcined and refined in the furnace, the removal of impurities would reduce the weight by half, which was equivalent to the small half of what they brought back was useless.

If it can be refined, the refined iron can be transported back, and the value of a trip is even higher.

Lin Yan nodded, "That's doable." But today is the 23rd of July, and we don't have much time left. Refining ore takes more time. ”

Lan Yue thought for a while and said, "It's better to separate the people, most of them are used to mine ore, and only a small team of ten people is used to refine ore." Take all the ore with you before you set off. ”

"This is good, after the furnace is built, as long as it is burned uninterruptedly, the ironmaking will be very fast." Mao Mu is very experienced in this, he has been involved in iron smelting, charcoal burning, etc., and is very familiar with the whole process.

The three of them looked at Mao Mu in unison, and their eyes lit up.

Hei Tu said happily: "Mao Mu is a talent, with him, it will not be difficult to make iron." ”

Lin Yan and Lan Yue nodded together, this is indeed a talent, he can do anything, he can do everything by himself.

Heitu said directly: "Mao Mu, I will assign ten people to you, and you will be responsible for ironmaking." ”

From this day on, Mao Mu took people to work non-stop every day, and it took three days to build a charcoal-burning kiln and three furnaces from local materials.

The mine is wooded and timber is everywhere, and everything is ready.

Two days later, the first batch of ore was excavated and put into the furnace for refining. From this day on, the furnace burned day and night for nearly a month.

Lin Yan and Lan Yue were not idle, they walked around the mine and collected countless new plants.

Looking at the contribution value that rises every day, Lin Yan is full of joy. With the Blue Moon here, the contribution value has risen by 1620 during this period of time, and she opened room 0108 and got a room full of professional books on iron smelting, detailing the forging of ancient iron tools.

At this time, they stood on the top of the mine, looking to the west, and they were in sight of the rolling mountains.

"Lin Yan, do you know what's on the other side of the mountain?"

Lin Yan shook his head, "The mountains are undulating, and there are mountains outside the mountains, who knows." I hope to be able to see it for myself in my lifetime. ”

"Let's go together." Lan Yue looked into the distance, her heart full of longing, "When you get out of the tribe, you will find the wonders of the world outside." It's dangerous, but I'd rather go out and walk around it all over again. Look at how big this world is, and whether there is a sea or not. Crossing mountains and mountains is also an achievement. ”

"That's what I want to do, too." Lin Yan looked down at his small body, "Wait a few more years, one day, we will cross the mountains and seas, measure the earth with our footsteps, and see the vastness of heaven and earth." ”

After finding iron, various tools came into being, and the process of change would be faster, and Lin Yan was not so worried.

A large number of children were born in Sun City, the way of feeding changed, the survival rate was greatly improved, and the population grew rapidly.

With the change of diet, the physical fitness of the person is enhanced, and the newborn is more robust. Young children have a great chance of cultivating spiritual power, and Hua Min has made statistics and can reach two percent.

Each of the children who have cultivated their spiritual power is the object of key training.

In a few years, when this group of children grows up, the status quo of Sun City will completely change.

Everything is moving in a better direction, and the future is just around the corner.

Retracting his gaze and looking at the foot of the mine, Lin Yan said: "A journey of a thousand miles begins with a single step, and we must do the things at hand first." Today is August 25th, and we have to leave for home. ”

Lan Yue nodded and said, "Black Earth ordered to go back on August 28. It's already coming to an end these days. I roughly calculated, there are 500 catties of refined iron, and about 1,000 catties of ore. Bringing it back creates a whole bunch of tools. ”

"It looks like a lot, but it's not enough." Lin Yan sighed, "Mining efficiency is low, and it takes longer to transport it back, or it's too slow." ”

"If there was a road to the mine, the delivery time would be much lower, and it would be better to build a refining plant here." Blue Moon had also thought about this question.

Lin Yan agreed, "Yes, it will take more than forty days to go back and forth now, and this is still a smooth situation." ”

After thinking about it, she continued: "Fortunately, you found wheat seedlings, and it is not impossible to build a road in two years." ”

Nowadays, the primary problem is to solve the food problem, and there is still too little food to satisfy the stomach. Only when they are well fed and clothed will people be willing to focus their energy elsewhere.

Lan Yue also understood what Lin Yan was thinking, and comforted: "We are not in a hurry, we have time." Let's go, go down and help pack things. ”
