After heavy snowfall, the weather in the wilderness has few sunny days, more rainy weather, cold and cold, and the temperature has not risen, but is more uncomfortable than heavy snow.

Two big brown bears, three big forest snakes, plus the inventory before the cold season, Monica and Sisi also go to the lake every day to crack the ice to fish, and they don't have to worry about food for the time being.

With nothing to do, Chu Yunfeng stood on the city wall, bathing in the sunlight that had finally come out for a while, thinking of the glittering stones he found when he and Sisi went to collect salt two days ago.

Is it really diamond?

If it is diamond, it is the hardest material in nature, a very precious mineral, and it will be used one day when it is stored.

"Roaring ......": Sisi, take the flat-headed brother to defend the city.

"Roaring ......": Saint Seiya, go out with me and carry your big backpack on your back.

When Chu Yunfeng and Monica left, they deliberately closed all the city gates and jumped out of the city from the city wall.

The last time they were easily attacked by the King of Vipers, their three forest pythons and two brown bears, such a mistake cannot be made again.

Chu Yunfeng walked in front, and Monica walked behind with a basket on her back, and a freshly roasted brown bear thigh was placed in the basket.

When I got closer, I could already see the mud and rocks that had been washed down, and many of them were shining in the sun. Closer, all black stones.

Chu Yunfeng's crawling speed was getting faster and faster, and he thought of a possibility, if it was true, not only could it solve the problem of heating, but also burn more good things in the kiln.

A large section of the mountain, washed down at the end by a mudslide, is covered with black, black dirt and black stones.

Chu Yunfeng was lying on top of the black everywhere, as if lying on the body of a female lizard, his eyes were full of excitement.

The open-pit coal mine, such a large open-pit coal mine, is not far from the estuary camp, and the national fortune wilderness is really good for me Chu Yunfeng.

Brought a handful of dead grass and lit it, picked up a few black stones and burned them inside, it burned very strongly, Chu Yunfeng and Monica stood on the side and felt warm.

After burning, the black stone scattered into a pile of dust, which burned very thoroughly.

It proves that this is still an open-pit coal mine with high purity.

"Roar ......": Saint Seiya, come, eat the brown bear's thighs together, and wait for the black mud and stones to go back, and carry as much as you can.

Monica didn't know what Chu Yunfeng was doing with these black mud and stones, but she was used to obeying Chu Yunfeng, so she didn't ask.

After Chu Yunfeng and Monica returned to the camp, Sisi also fixed a big back basket on her back and followed Monica to carry coal, and Chu Yunfeng took Pingtou Brother and them to dig a pit in the camp house.

The circular earthen pit, not very deep, has a ventilation hole dug next to it leading to the outside of the house. The top of the round pit is built with lime and mud on the stove, perfect.

Monica and Sisi carried back the coal, Chu Yunfeng asked Brother Pingtou to dig up a large basket of loess, mix it with water and stir it to make a "cylinder" that was not very good-looking, and inserted a lot of small holes in the middle with a stick.

Honeycomb coal, done.

Monica and Silk carried their backs until it was dark, and there were at least ten tons of coal piled up in the middle of the camp.

"Little lizard, get back so much black stuff, ready to burn it?" Monica moved there to carry coal for a day with some sore shoulders.

"Roar ......": You'll know tomorrow.

Neither the honeycomb coal nor the stove plaster are yet dry, and they will not be used until they are dry tomorrow.

"The state of Chu has obtained 1,000 open-pit coal mines with a storage capacity of 1 million tons."

When darkness descends, the words of the national fortune wilderness make the other saviors in the wilderness not know what happened, and the survivors of the countries outside do not know what happened.

The survivors of the Chu Kingdom and the Dongban Kingdom witnessed all the things that Chu Yunfeng and Monica did today, and they were also a little puzzled by what the big role of these coal mines was.

likes to fart (Chu State): "Has anyone come out to explain, what is the use of these coal mines?" ”

The widow of the village (Chu Guo): "Earthworms, marmots, you two, one is engaged in river channels and the other is digging holes, can you explain?" ”

Black earthworm (Chu State): "I'm engaged in water conservancy, how do I know what these black things are for?" ”

Groundhog (Chu State): "Didn't the lizard god set them on fire with withered grass before?" I guess it was used to make fire! ”

"Fire? Is it better to use firewood directly? ”

"Perhaps...... Hey, I don't get it either. ”

"I think these black things can be used for writing, but I don't know if they can be kept for a long time."

"I just tried, it didn't work, the water flushed, and it was all gone."

……

Junsheng Taro (Higashizakura Country): "Hehe, I thought that Chu Guo got something amazing, but it turned out to be some chicken ribs." ”

Freedom Fighter (Free Country): "Junseitaro, where did you and the Beast Forest King go?" We've been waiting for you here for months, and we haven't waited for you. ”

Junsheng Taro (Higashi Sakurakuni): "The cold season is too cold, so we dug a cave here to protect ourselves from the cold, and then we continued walking when the cold season passed. ”

Freedom Fighter (Freedom Nation): "Why don't you tell us in advance if you don't leave there?" More than a dozen of us have been waiting for you here for so long. ”

Soul Witch (Great Han Country): "Hehe, you didn't ask. Ever since we decided to flee to the Free Nation, when did you Free Nation ever care about us? If we hadn't left Higashizakura with enough food, we would have starved to death on the road. ”

Freedom Fighter (Free Country): "What do you mean?" We're stupid waiting for you here, and we're waiting for you wrong, aren't we? ”

Beast Forest King (Great Cold Kingdom): "Okay, what are you yelling about?" In such a cold weather, you don't have the ability to hide in the cave and not move, you should come out and go to your free country! What are you waiting for us, it's not because the cold season is coming, you don't dare to go! ”

Freedom Fighter (Free Country): "You ......"

The freedom fighters and Junsheng Taro began to fight with each other in the live broadcast room of the Chu State, and the survivors of the Chu State and the Dongban Kingdom did not drive them away, nor did they ignore them, so they should watch the show.

On the other side of the estuary camp, after Chu Yunfeng ate a few dried fish, he lay down next to the fire and began to fall asleep.

Today, with such a large open-pit coal mine, Chu State and Dongban Kingdom jointly obtained a thousand large coal mines, Chu Yunfeng felt that he needed to communicate with the Holy Maiden, otherwise, it was very likely that the survivors of Chu State and Dongban Kingdom would not know the importance of coal mines.

The Holy Maiden has been praying for Chu Yunfeng in the Lizard Temple during this time.

When the cold season came, it was cold outside, and the saint wore clothes and pants made of wood fiber, with a leather shoulder on her head, holding the "lizard suit" that she had been holding for nearly a year, except for occasionally eating some food sent by the tribe and sleeping, the rest of the time was in prayer.

As soon as Chu Yunfeng entered the state, he immediately saw the holy woman sitting there praying for blessings.
