"Hahaha, it's really effortless! There must be more or less combustible coal mines around here, and now there is even more fuel for smelting copper ore, God help me!" Ye Feng laughed maniacally, not feeling the strange eyes of everyone looking at him.

In the end, Chu Yun couldn't stand it anymore, poked Ye Feng with his arm, and said disdainfully: "Enough, look at the way they see you." ”

Ye Feng suppressed his smile, ignored those eyes directly, pointed to the coal and said, "With this coal, we have all the fuel for our agricultural copper mine." ”

"Isn't it the same to burn wood?" Chu Yun asked, she didn't know much about this aspect.

"That's different, copper has a melting point of 1084°C, and no matter how much wood you add, you can't reach that temperature, while coal is a breeze."

"Okay, I don't understand that, you can figure it out yourself."

"Well, you go around and look for this black stone, it's very important!" Ye Feng said to everyone.

Everyone thought they would look at me and I would look at you, and they all saw each other's hesitation. Gray walked out of the crowd and said, "Brother Ye Feng, you better stay away from that stone, there is a demon here, otherwise how could it burn?" ”

Ye Feng felt that it was still necessary for him to explain the origin of the coal, lest they become afraid of the coal: "There is no demon on this stone, and there is no curse of the gods, it is the same thing that can be burned like the wood we usually burn. ”

The crowd was shocked, there was no demon, how could the stone burn? So everyone's curiosity was aroused, and they waited for Ye Feng to continue talking like a well-behaved kindergarten baby.

"Hundreds of millions of years ago, the forest that grew luxuriantly here was buried deep in the ground for some reason, and through various chemical and physical reactions, it turned into a black hard stone, and then lifted to the surface through the movement of the earth's crust, which made us see the ......" Ye Feng said this, and suddenly stopped, because he knew that his head was about to explode.

"What are billions?"

"What is the year?"

"How did they get buried?"

"What is chemistry?"

……

Everyone was gossiping, every word you said and I said, and all kinds of problems flew towards Ye Feng like snowflakes, bombarding Ye Feng with dizziness and headaches.

"Stop!" Ye Feng saw that answering this was not answering that, but only roaring.

The sound was as loud as thunder, and the noisy crowd was instantly silent, which could be described as silent, because after this roar, the surrounding birdsong was also silent.

"I'll answer these questions in the tribal class, in short, there are no demons on this stone, and there is no curse from the gods, the only danger is that your hands slip and you hit your feet during the transportation. Now, I want you to find this black stone for me, and don't eat tonight if I don't go!" ”

"Uh, Ye Feng." Chu Yun pointed straight to the sky and said, "It's this time, how can I find it?" ”

Ye Feng stared at the moon above his head, felt that his old face was hot, coughed lightly, and said, "Eh, what's this, I'll go again tomorrow, I'll go again tomorrow, eat, eat!" ”

"I'm not done yet, are you going to carry this coal to the copper mine, and are you carrying the copper mine and coal home?" Chu Yun clasped his hands in front of his plump chest, and his eyebrows and eyes crooked and smiled into crescent moons.

Ye Feng's voice seemed to be squeezed out of his teeth: "Can you save some face for me, little girl?" ”

"Face? What doesn't exist, primitive people don't understand it anyway. ”

Well, this is very pertinent, Ye Feng is speechless.

"Don't look for coal, eat, eat!" Talking about this girl, Ye Feng could only change the topic, ignoring the triumphant Chu Yun, and took out a few handfuls of jerky from the bag made of animal skins, and threw them into the already boiling clay pot with a bang.

After a simple supper, they found a leeward spot, picked up the animal skin tents, and fell into a deep sleep, until a ray of sunlight appeared on the eastern horizon, filled their stomachs casually, and set out on the journey again.

The prospecting road is undoubtedly arduous and difficult, especially in this wilderness where there is no road, there are all kinds of dangers to face, jackals, tigers and leopards These dangers are still small, and the most terrifying thing is to get lost in the uninhabited wilderness.

"Gray, are you sure you're going here? How I feel like we've been here. Ye Feng looked at his surroundings and said to Gray.

Gray, who was walking in the front, turned around with an apologetic smile and said, "It's possible, it's mainly because it's been too long, and the trees here don't grow the same as before, which is a little hard to recognize." ”

"Okay, you can keep walking, only you can vaguely remember here, we don't know anything about this place." Ye Feng knew that the more urgent he was in this situation, it would only make him more and more unable to remember the original direction, so he had to retreat and advance.

Ye Feng pulled out a stone axe from the straw rope of the animal skin around Liu Junting's waist, cut a mark on a tree, and motioned for Gray to continue moving.

After a while.

"Gray, wait a minute, we're back again!" Ye Feng saw the tree he had left a mark on earlier, and said to Gray in front of him.

Seeing that Gray fell into memories, Ye Feng said to the people behind him, "Let's take a rest first, but Chief Gray thinks about it first, we are leaving." ”

Time passed, and Gray was still there, meditating, motionless, like a wax figure.

Seeing the thick sweat on his forehead, Ye Feng said: "Don't be in a hurry, think slowly, think about whether there are some things that can be referenced, such as some stones, soil slopes, mountains, and trees, don't think about it, after all, it has been so long, and these trees have long since changed." ”

"Stones! That's right, the stone! I remember that there seemed to be a big rock that looked like a monkey in the vicinity, and there was a small stream next to it, and if you climbed up this stream, you could see a mountain, and then ...... What could that be? Gray patted his head at first, and then tangled up the road ahead, scratching his ears and cheeks in a hurry, and a few strands of hair were scratched off.

"Don't think about the rest of the world, let's go find the big rock that looks like a monkey first, and we'll talk about it when we get there." Seeing him like this, Ye Feng was afraid that he would fall into the blind spot of thinking, so he hurriedly said.

"Let's go find a big rock that looks like a monkey, and if we find it, we won't have to go around in circles here!" Liu Junting said to the crowd behind him, making Ye Feng praise him for finally being smart.

So the people began to look for the big rock that looked like a monkey, because it was in the dense forest, the view was blocked, so it was very difficult for people to find this big stone.

"Big rock! A stone that looks like a monkey! Is there or not! Standing tall and looking far away, the twin brother Right Das, who was climbing on the treetops, said on a hill opposite.
