A piece of rotten wood that was exposed to the sun for a long time was cushioned from the outside of the coconut, and a wooden stick of uniform thickness was placed on it.

Lu Yuan held the wooden stick.

Keep rubbing left and right.

And I feel that my hands are going to be scrapped.

It is really difficult to drill wood to make fire.

Lu Yuan really understood this point, no wonder he invented the fire knife, fire chuck and even match lighters in later generations.

It took primitive humans millions of years to master fire proficiently, and it is unreasonable.

While thinking about this, Lu Yuan took a look at the sky.

In the rest of today, they picked up forty or fifty big coconuts here, saving some food enough to eat for more than ten days. Seeing so many coconut trees by the sea, they can be said to rely on the mountains and sea to eat the sea, and rely on the coconut trees to eat the coconut trees.

As long as you don’t consider the problem of eating disgusting, at least the problem of eating is solved now.

Especially after coconut, freshwater is not so scarce, Lu Yuan suddenly realized this.

Of course, the coconut milk in the coconut can only be used as a drink. Other things like washing, cooking, washing vegetables, and bathing are still not allowed to interfere.

After taking the coconut, the two of them carefully searched for some dry and hard firewood nearby. As reserved firewood, if you want to build a house, it is definitely impossible in the short term. You can only camp in the open air. In this case, a bunch of bonfires are indispensable.

The so-called drilling wood to make fire is really everything is ready, only the east wind is not available.

The problem is that when the east wind is drilling, the east wind will not come for a long time.

It is really difficult to drill wood to make fire.

At this time, the twilight was already drooping. Because the sea had no cover, there were always large areas of burning clouds on the sea sunset.

"Let me try it?" Su Mei, who was standing beside him, couldn't help but speak.

Lu Yuan smiled and took out another wooden board for Su Mei - the two of them actually prepared a lot of dry wooden boards.

Su Mei nodded, and he also learned from Lu Yuan, cushioned the dry coconut fiber next to him as turtle velvet to attract fire, and then picked up a stick and started to rub it.

However, for some reason, I clearly saw Lu Yuan rubbing hard for a long time without any reaction. After rubbing this place for about ten minutes, I saw a stream of white smoke coming out.

Su Mei peeked at Lu Yuan and found that Lu Yuan was still working tirelessly there, so she secretly turned away and blocked Lu Yuan and looked towards him.

Then continue rubbing, continue rubbing.

"Su Mei, I seem to smell a little burnt." Lu Yuan said, only saying that the world is really real: "I think I may be almost successful."

The girl pursed her lips and didn't say anything. In front of her, the white smoke was almost rising. Su Mei saw a cluster of bright red flames rising, and then completely swallowed the entire dark brown coconut fiber tinsel.

"I'm fine!" Su Mei jumped up and said loudly.

Lu Yuan looked at Su Mei and saw a bright flame burning on the wooden board in front of Su Mei.

The wooden stick in Lu Yuan's hand fell to the ground, and the stick head was charred.

...

...

"This is unscientific." Even when facing the raging fire in front of him, Lu Yuan was still very unwilling to accept it.

Why is he, an adult, not as good as a child as Su Mei?

But I have to say that the fire-roasted coconut is really fragrant.

With the fire source, Lu Yuan and Su Mei could quickly create a bunch of decent bonfires. The only thing to consider is that Lu Yuan needs to ensure that the fire pit is immortal for a long time. Just like in the caves where primitive humans live, the fire pits they use to preserve fire will often continue to burn for several years or even decades, because once they lose the fire at that time, they may not be able to get such valuable resources again in the next few hundred years.

Unless you go to other tribes to seek their fire.

This method is somewhat similar to the transmission of the Holy Fire.

In short, after the fire is raised, all the coconuts harvested before are thrown into the fire pit and stewed. Although I have never tried this way of eating coconuts before, from the traditional thinking of Huanglong Kingdom, no matter what, roasting will definitely be more delicious than eating raw.

However, before starting to roast the coconut, Lu Yuan looked at Su Mei: "Can you tell me the trick?"

Su Mei turned her head. Although she was very proud, the girl couldn't tell her the trick at all.

"Isn't it just a circling?" Su Mei said.

"I'm obviously also circling?" Lu Yuan was really dissatisfied. They actually prepared a lot of wood-drilling materials. They had already planned to prepare for a long-term war of resistance, but unexpectedly, under the premise that Lu Yuan started the game, Su Mei won the championship, which made Lu Yuan feel very unhappy.

"Why do we compare again?" Su Mei said with a smile.

"Just compete." Lu Yuan nodded. Now the two of them really have nothing else to do in this world. If the bonfire is already ready, the two of them have collected a lot of firewood for burning. It is impossible to explore other places in the dark now, so they can only chat next to the fire and wait for roasted coconut.

Well, the toasted coconut tastes very fragrant.

After the two decided, they redistributed the chopping board and stick needed to drill wood to make fire, as well as the same amount of turquoise. However, this time, Su Mei still followed the rhythm of the last time, but it was not as smooth as last time.

Instead, he heard Lu Yuan screaming in surprise. When he looked back, Lu Yuan had already received the curling white smoke. It seemed that he was only one step away from the last fire.

When Su Mei turned her head and continued to concentrate on drilling wood, Lu Yuan was already showing off his nature and showed Su Mei the wooden stick lit by his flames.

"It's just that you're lucky." Su Mei was a little unhappy with the failure this time and said angrily.

But Lu Yuan shook his head: "I don't feel lucky this time."

"Hmm?" Su Mei looked at Lu Yuan and said no.

"All luck ultimately comes from science and probability. We humans are the same, the way of drilling wood is the same, and the materials that cause fire are the same, but the first time you succeeded and I failed, but the second time it turned out the other way." Lu Yuan looked at Su Mei under the firelight: "I think this is not just luck, but it has something to do with the materials we use to drill wood."

"Is it related?" Su Mei felt that it shouldn't be related?

However, Lu Yuan had already shown Su Mei the two chopping boards that the two had drilled into wood: "I chose the chopping board this time on purpose. What's the difference?"
