The Firmament Tribe, Zhan Qingtian has moved to a warm cave.

This is a cave, but it is not, this kind of hole is dug by hand.

According to Dawu, this is called the cave, which is warm in winter and cool in summer, and then a high platform made of clay is placed in the cave, which is called Kang.

The Firmament Tribe suffered the least loss in this disaster, and they had prepared enough food and that kind of black fuel at the beginning.

Though these things are as hard as stone, but they can burn like wood.

In his cave, it was as warm as spring.

There were also other tribes who came here to exchange fuel with them, but Zhan Qingtian told them that if they wanted fuel, they could exchange it for the meat in the tribe.

This blocked a lot of people's roads at once.

But the last two days have been different, and many people have come to Zhan Qingtian with food from the tribe, just to exchange for a little black stone.

It seems that the Great Witch is right, this method can unify this land in the fastest time, this is called economic warfare.

"I have inexhaustible stones here, but the food you have there is limited, use the food for fuel, and when the food you have there is finished, you can only come to the Firmament Tribe, and the Firmament Tribe can easily control that most of the lives are dead!" Zhan Qingtian was making his calculations at the moment, and only people like Dawu could think of such a plan.

"King, the people of the women's tribe are here!" a soldier came over to report to Zhan Qingtian.

"Women's tribe? Aren't they very backbone? I heard that their food has long been eaten, how can they still have the face to come to our side? You tell them, it's not available, it's gone!" Zhan Qingtian still resents the fact that this women's tribe defeated him.

"King, they are here this time with a man, and they said that you will definitely see him when you see this!" the soldier presented a box.

The workmanship of this box is not exquisite, it can only be said to be so-so.

Zhan Qingtian opened the box quite meaningfully.

Inside the box, there are sharp daggers.

This dagger is exactly the same as the one of the Great Witch, Zhan Qingtian closed the box, and then said to the little soldier: "Let him in!"

Chen Fan picked up the door curtain made of animal skins and strode in.

This was the first time he had seen Zhan Qingtian, and the purpose of this time was to see the veins of the Firmament Tribe.

As long as he can see the direction of the ore veins here, Chen Fan can find out where there is ore.

"What do you mean by giving this to this king?" Zhan Qingtian was holding the dagger, and he was sharpening a roasted beast leg!

"It is said that the treasure knife is worthy of a hero, this knife is a treasure knife, give it to you, the king!" Chen Fan gave a salute to Zhan Qingtian.

"You guy, you can talk, I took this knife, what do you want?" Zhan Qingtian wanted a knife like this for a long time, but he never had a chance, but he didn't expect this guy to send it over this time.

What Chen Fan gave Zhan Qingtian was the bayonet he picked up, this thing was of little use to him now, there was no more fuel available in the entire tribe, and it was useless to keep a broken knife.

"I want to see your black stone, my lord!"

"Look, as long as you open your mouth, I'll give you a basket of stones here!" Zhan Qingtian is very happy now, he has this knife, even if he gives the other party some stones, it is nothing, they have more here.

"If you are willing to give your people some stones, that would be the best, and if you let me see how the stones grow, you will be fine!"

"Haha, what grows out, this thing is called coal, there are more underground, it's just that we know how to mine!" Zhan Qingtian is quite proud, even if these things are used by others, they may not be able to use them.

"I admire your foresight very much, and I hope that you will be successful!" Chen Fan patted his farts disgustingly.

Chen Fan, led by a bunch of soldiers, came to the coal mine.

It is indeed an open-pit coal mine, and many tribal soldiers are digging for coal.

Chen Fan took a closer look, carried a basket of coal, and left here.

Some things were spinning rapidly in his mind, this great witch taught Zhan Qingtian to build caves and dig coal, indicating that this person was also from outside, but why didn't he think of this?

Caves don't have to be built, but coal mining should be possible.

"Send someone to dig coal for them, so that the people of the Firmament Tribe are idle by themselves, as long as the dug coal is left for their own side, and the excess is given to the Firmament Tribe, isn't it okay. Qin Keren, who came with Chen Fan, dressed up as a man and secretly said to Chen Fan.

Chen Fan slapped his thigh and couldn't help but say, "Why didn't I think of it!"

Chen Fan told Zhan Qingtian what he thought, but he didn't expect that Zhan Qingtian agreed at the first time.

This is a good thing, if there are people from other tribes to help him dig, the soldiers on his side will be idle, and he will have more people to help him expand his territory.

"Okay, you're very promising, follow me, right?" Zhan Qingtian sent an invitation to Chen Fan.

"The king, the little ** son is from the women's tribe, and I can't honor the king, but if I have any good way, then I must tell the king in advance!"

When Chen Fan was chatting with Zhan Qingtian, there was a sudden chaos outside.

The mining soldiers rushed to tell each other, and ran towards a place with weapons in hand.

"Let's go, follow this king to have a look!" Zhan Qingtian took the bayonet in his hand and walked out of the cave.

"What's going on?" In front of a dug mine, Zhan Qingtian grabbed a small soldier.

"There's something in this cave! I've already wounded several people!" the soldier stared at the entrance with a bow and arrow in his hand.

"Did you send someone in to see it?" Zhan Qingtian asked.

"Go, our captain took three people in, but after such a long time, there was no reaction at all, it is estimated that there is more than one bad luck!" The little soldier looked solemn, and he didn't dare to relax for a moment!

"Quack!"

A frog's cry came from the mine.

The people gathered outside the mine took a step back.

A gust of fishy wind came out, and it almost didn't smoke Chen Fan.

"What is this, so disgusting!" Chen Fan covered his nose, extremely uncomfortable.

"Quack!"

Another frog's cry came out, this time louder, and it seemed to have reached the mouth of the cave.

Chen Fan stared at the entrance of the cave tightly, and saw a black thing slowly crawling out of it.

His big mouth opened, and a tongue rolled over, directly sweeping away a soldier.

"Toad essence?" Chen Fan stared at him carefully, motionless.

The soldier was already in a bit of a commotion, and some of the soldiers were already starting to shoot arrows at the black thing.

This guy has rough skin and thick flesh, and the soldiers' weapons can't do any harm to this guy.

In the blink of an eye, he had crawled out.
