The end of the hunt in the barren grassland does not mean that they can rest, and they still have to spend the next two months in the dry season.

If you want to survive the cold dead season, in addition to adequate food, you must also ensure that you can get enough heating.

Therefore, firewood is also an important material that must be stocked up before the dead season.

According to the direction pointed by Yong, after Lin Luo rushed to a small hill near the tribe, he suddenly saw a hot scene.

All the newcomers to the previous hunting party are now cutting down trees with stone axes in their hands.

As totemic warriors, they naturally cut down trees at a much faster rate than ordinary people, and every few minutes they could see a large tree fall to the ground.

"Get out of the way, the tree is falling!"

Lin Luo had just arrived here when he heard a familiar shout.

Turning his head to look in the direction from which the voice came, he saw Stone Mortar standing next to a large tree whose pole had been cut down for the most part.

After shouting, Shi Jiu directly clenched his fists and punched the tree pole fiercely.

"Squeak!"

Suddenly, with a cracking sound, the big tree fell to the ground with a bang.

"Lin Luo, why are you here?"

After the big tree fell to the ground, Shi Jiu also found Lin Luo who had rushed over, and immediately asked him with a happy face.

"I'm fine, so come over and see if there's anything I can do to help. ”

Lin Luo replied towards the stone mortar.

After speaking, he turned his head to look at his surroundings.

Since a large amount of wood is burned for heating during the dead season every year, the tribe also selects a nearby hill every year for large-scale felling.

The felled trees are not immediately transported back to the tribe, but are decomposed on the spot, chopped down to a size suitable for a campfire, and then dried in the sun.

When the felling is complete, all the firewood is transported back to the tribe.

This not only makes it easier to transport to the tribe, but the sun-dried wood is much lighter than the freshly cut wood.

And with such a huge amount of work, it is naturally impossible for only a few newcomers to complete it.

At this time, the hunting party of ordinary warriors had also finished their hunting, and they were also doing the work of chopping tree poles and drying firewood here.

If only there was an open-pit coal mine nearby!

Looking at the busy figures around him, Lin Luo couldn't help but fantasize in his heart.

How he wished at the moment, as he had done the last time he had discovered a spring, a coal mine nearby, preferably anthracite.

In that way, the summer season and the dead season, which are like natural disasters, will not have much impact on the bamboo tribe.

But it's a pity that he can only think about this beautiful wish in his heart.

"Coal!"

In the end, Lin Luo let out a sigh and let himself stop thinking about this wishful thinking.

Then, he turned and walked to the stone mortar, ready to cut down the trees with them.

However, after just a few steps, Lin Luo suddenly stopped.

"Coal? Yes, coal! There is no coal, but I can burn charcoal!"

Lin Luo muttered to himself, and his face soon showed an expression of excited ecstasy.

Then, he looked at the dry firewood piled up not far away.

Compared with firewood, charcoal after firing undoubtedly has many advantages.

For example, charcoal is very easy to ignite and very lightweight.

When burning, there will be no flames and smoke, no choking smell, and the harmful substances produced are much less than burning firewood.

Because the bamboo hut is not very warm, after the dead season comes, everyone in the tribe will move to a cave halfway up the mountain to live together.

The memories of the original owner made Lin Luo deeply understand that spending the dead season in a cave full of smoke and choking smell was a very difficult time.

And, more importantly, the calorific value of charcoal is nearly twice as high as that of firewood, which will undoubtedly have a better heating effect to help the tribesmen survive the cold dead season.

After secretly thinking about it in his heart, Lin Luo immediately took action, and directly turned around and walked to the place where the dry firewood was stacked.

Burning firewood into charcoal, although it sounds simple, is really not a simple thing.

In ancient China, people have begun to use charcoal for heating, at that time they were all building special charcoal kilns, and skilled potters must be skilled to master the heat.

Because the fire is too large, the firewood will be burned directly to ashes, and the fire is too small, and the firewood cannot be burned thoroughly, and it looks like charcoal on the outside, but it is still wood on the inside.

Lin Luo: Does he know how to build a charcoal kiln?

Obviously he didn't understand, he hadn't even seen it.

Lin Luo, can he master the heat?

This is obviously something more unlikely.

But despite this, Lin Luo did not have the slightest sadness on his face.

Because, he never thought of using a charcoal kiln to burn charcoal.

Since it is in the primitive world, it is natural to use a simple and crude primitive method to fire!

Soon, after clearing a clearing next to the stacking of dry firewood, Lin Luo planted a branch in the center of the clearing, and then began to pile firewood around it.

He first chose small pieces of firewood, and then gradually piled them up densely from small to large without leaving gaps, and soon formed a conical firewood pile with a diameter of about one meter and a height of about one meter.

"Lin Luo, what are you doing here?"

Seeing Lin Luo's actions, everyone who had temporarily stopped to rest immediately gathered around and asked him curiously.

"Burn charcoal. ”

Lin Luo looked at the firewood pile in front of him with satisfaction and replied with a smile.

"Charcoal? What is charcoal? Can you eat it?"

Hearing Lin Luo's answer, Stomach Armor asked curiously.

"Charcoal is not eaten, charcoal is made from firewood that has been burned and can be burned for heating. ”

Lin Luo replied towards the stomach armor, and then continued: "The stomach armor, you go and help me move the bamboo jar over there." ”

Near here, there are many large bamboo tanks filled with water, which are used by the warriors to quench their thirst when they are tired from cutting down trees.

"Oh. ”

Hearing Lin Luo's words, the stomach armor immediately nodded and ran to move the bamboo tank.

"Lin Luo, these firewoods are all cut by us, and if you burn them like this, then won't our efforts be in vain!"

When the stomach armor went to move the bamboo tank, Feng's unhappy voice also sounded.

This time he didn't target Lin Luo, just because Lin Luo's explanation made him unconvinced.

In his cognition, after the firewood is burned, there is ash left, how can it burn again.

Even if Lin Luo really had a way to turn firewood into charcoal after it was burned, how long would it burn again after burning it once?

The dead season already needs a lot of firewood for heating, and burning it once like this is a waste of firewood in his opinion.

"That's it, Lin Luo, you're wasting firewood. ”

"Isn't the wood turned to ashes when it's burned?

......

There were not a few warriors around who had the same idea as Feng, and they all spoke to Lin Luo.

"As for the benefits of charcoal, everyone will understand it when I burn it. ”

In this regard, Lin Luo did not explain too much.

Because here, it is useless to talk so many big truths, and only by speaking with facts can you be convinced by others.

While Lin Luo was talking, the stomach armor had already moved the bamboo jar over.
