"Stomach armor, you help me dig a pit in the ground, and then pour the water from the bamboo jar and some thin mud into it. ”

Looking at the stomach armor that brought the bamboo jar, Lin Luo continued to ask him for help.

"Good. ”

Hearing this, the stomach armor nodded very simply in agreement.

Lin Luo himself, on the other hand, found some dead leaves nearby and scattered them on the firewood.

Looking at Lin Luo's actions, everyone didn't say anything more this time, but their faces were full of curiosity.

After all, Lin Luo had already said just now that he wanted to burn charcoal to prove it for everyone to see.

Moreover, it is only a small pile of fire, and it is not a big deal.

If Lin Luo burned all the dry firewood, then they would definitely not agree.

Soon, after covering the firewood pile with a layer of dead leaves, the mud on the stomach armor had also been reconciled, and Lin Luo directly grabbed the mud and pasted it on the firewood pile.

It didn't take long for the original firewood pile to become a mound, and Lin Luo deliberately left a hole at the top of the mound, which was not completely sealed.

Looking at this mound, which looked like a grave, Lin Luo squatted down and dug out eight air intakes evenly around the bottom of the mound.

Then, turning to the curious crowd, he said, "Who's going to help light a fire for me?" ”

"I'll come. ”

Immediately one of the fighters volunteered.

Soon, after the fire was raised, Lin Luo put the fire on the round opening left at the top of the mound and lit the dry firewood piled up in the mound.

After doing all this, Lin Luo patted his muddy hands with satisfaction and found a place to sit down.

"Charcoal fired?"

Looking at Lin Luo, who was sitting down to rest, Feng asked him curiously.

"It's just been lit, how can it be fired!"

Hearing Feng's question, Lin Luo rolled his eyes directly at him.

"How long will it take to fire?" Feng continued.

Hearing this, Lin Luo estimated in his heart and said, "It will take a long time." ”

“......”

Hearing Lin Luo's words, Feng and the other warriors around him all showed speechless expressions.

They stood here waiting, but they all wanted to see how good the charcoal was in Lin Luo's mouth.

But he didn't expect that Lin Luo would directly pay it a long time later.

Now is the critical time to store dry firewood, and naturally they can't all stand here and wait for the charcoal to be fired.

So, soon the crowd dispersed and went on cutting down trees.

Because it was the first time to burn charcoal, in addition to setting up a flag in front of everyone just now, in order to prevent the failure of charcoal burning and being slapped in the face, Lin Luo did not dare to leave, and he has been paying attention to the firing situation at all times.

When a fire is lit at the top opening, an updraft is formed inside this simple mud kiln, and the fire burns downwards in the direction of the air flow.

The downward flame will consume the oxygen in the updraft, so that the charcoal that has been burned in the upper layer will not be burned to ashes.

This is the simple principle of stacking and burning charcoal.

The first time Lin Luo knew about this method was when he was watching a video at station B before, and he accidentally saw a video of the [Original Technology] series uploaded by the UP master.

In the video, an Australian brother uses such a simple and primitive method to burn charcoal.

Before, when he made bows and arrows, he also used some knowledge he learned from the Australian brother's video.

Thinking of that little Australian brother, Lin Luo couldn't help but sigh in his heart.

His video was first uploaded by the UP master in 15 years, and Lin Luo has been paying attention to it until 18 years and is still updating at a turtle speed, and has been praised by many barrages as a lifetime series.

Even Lin Luo himself even sent a barrage to lament his lifetime!

Now, he doesn't know if others have a lifetime, anyway, he hasn't seen the end in his lifetime.

Lin Luo thought about it carefully, before he inexplicably crossed here, the last update of the video seemed to be that the little brother was building a pit iron-making furnace with a chimney.

"I don't know, now the Australian brother has smelted iron. ”

Thinking of this, Lin Luo couldn't help muttering to himself.

After all, the little brother has failed several times before.

......

In the busyness of everyone, time flew by, and soon five hours passed.

"Lin Luo, is the charcoal really as good as you say?"

The chief glared at his tiger eyes and asked Lin Luo with an expectant expression.

The chief had come two hours earlier, and had come to check on the progress of the tree felling.

But he happened to find Lin Luo who was burning charcoal, so he asked him.

Regarding the chief's inquiry, Lin Luo naturally didn't dare to be perfunctory, so he simply talked about several advantages of charcoal.

After hearing Lin Luo's description of the advantages, the chief immediately became interested in charcoal, and directly chose to stay and prepare to witness the birth of charcoal.

"You'll find out when you see it for yourself. ”

Lin Luo answered the chief's inquiry while using mud to seal the air intake at the bottom of the mound, where the fire could already be seen.

This is the last of the eight air intakes.

After sealing all the air intakes, Lin Luo picked up a larger piece of mud and sealed the hole at the top of the mound.

After doing this, Lin Luo finally breathed a sigh of relief and said with a smile: "Okay." ”

"Charcoal fired?"

"What does charcoal look like, hurry up and take it out for us to see. ”

"yes! ”

......

Hearing Lin Luo's words, the surrounding soldiers immediately spoke out expectantly.

Originally, today's task of cutting down trees could have ended a long time ago, but in order to see the charcoal that Lin Luo said with their own eyes, all the fighters did not leave.

"Take out the charcoal and show me. ”

The chief was also a little excited, and immediately said to Lin Luo.

"It's just a preliminary firing now, and it needs to be cooled overnight before it can be opened tomorrow morning. ”

Looking at the excited crowd around him, Lin Luo explained helplessly.

“......”

As soon as Lin Luo said this, the surroundings instantly fell silent.

There is such a saying, I am most afraid of the sudden silence of the air!

Originally, Lin Luo saw that everyone hadn't left, and thought they were all waiting for him to go back together.

But he didn't expect that it was just his own passion, and everyone stayed until now because of the charcoal.

The chief was even more choked by Lin Luo's words, and his face was flushed, and he couldn't say a word for a long time.

He waited here for more than two hours to see the charcoal for the first time!

As a result, Lin Luo actually came to such a sentence in the end.

Seeing that the chief's gaze gradually became very unfriendly, Lin Luo suddenly had a wry smile on his face.

I couldn't help but secretly worry in my heart, if I found that the charcoal burning failed when I opened it tomorrow, the chief wouldn't take the opportunity to beat himself up to vent his anger, right?
