Following

I have to say that the effect of cleaning is still very significant.

Although there was still a slight smell in the bamboo house, and there was still some itchiness on his body, compared to the day before yesterday, Lin Luo slept relatively well last night.

In the morning, when buckwheat came to deliver food, he finally brought water for them, although it was not much, only enough for each person to drink two small sips, but it was enough to make all the children crazy with joy.

At the same time, buckwheat also brought news that the chief had reorganized a new water fetch team and was ready to set off again tomorrow to fetch water from the Great River.

Lin Luo didn't care about this, the only thing he cared about now was how he wanted to survive here.

"Do you have everything with you?"

Lin Luo turned his head to Gu Cao and asked.

"Bring it all. ”

Gu Cao nodded, and patted the large and small seven or eight bamboo tubes hanging on his body.

Seeing this, Lin Luo also bent down to pick up a large bundle of dry firewood on the ground, and waved his hand vigorously: "Let's go!"

Whether or not we can dig up water to survive this summer season depends on whether we can succeed this time.

"Hmm. ”

Gu Cao nodded again, and immediately followed Lin Luo's footsteps towards the mountain.

Seeing Lin Luo and them carrying so many things up the mountain, the other orphans who had just finished drinking water didn't pay attention to it, and they all shrank back into the bamboo hut and lay down again.

Generally speaking, unless it is the busiest time for the tribe in the dry season, the tribe usually does not arrange any labor for these children.

And years of starvation have taught them that lying still can make hunger pangs come on more slowly.

Half an hour later,

Coming to the place where the stone crevice seeped water again, Lin Luo threw the dry firewood to the ground and ordered Gu Cao to make a fire with drilled wood, while he himself bent down to uproot all the shrubs around the stone crevice.

Gu Cao's technique of drilling wood to make fire is relatively skilled, and it didn't take long for the fire to be raised.

"Put it here. ”

Seeing that the fire had risen, Lin Luo immediately asked Gu Cao to put the fire in the crack of the stone.

"Luo, aren't we looking for water? Why do we want to make a fire?"

For Lin Luo's instructions, Gu Cao would always do it first, and then raise the doubts in his heart.

"Whether we can find water this time depends on whether the fire burns vigorously or not. ”

Lin Luo smiled and patted Gu Cao's shoulder, without explaining much.

Thermal expansion and cold contraction!

This principle is understood even by elementary school students on earth.

The great ancients of China used this way to open mountains and crack stones.

Faced with this huge stone that could not be smashed with brute force, Lin Luo naturally had to use the wisdom of the sages to solve this big problem.

However, it is undoubtedly a very troublesome thing to explain this principle and Gu Cao, who is extremely lacking in cognition.

Therefore, Lin Luo simply stopped wasting his tongue and did not explain too much.

As for Lin Luo's words, Gu Cao, who has been a fart since childhood, has always believed unconditionally, so he didn't continue to ask, and immediately squatted down to add firewood to the fire that had just risen, and made it burn more vigorously as much as possible.

Playing with fire in hot weather is obviously not much different from adding fuel to the fire.

Feeling the heat wave coming to his face, Lin Luo threw the dry firewood into the fire, and immediately pulled the grass to hide far away.

The dry firewood burned with a crackling sound from time to time, and it lasted for more than half an hour before the large bundle of dry firewood burned out.

It was only then that Lin Luo walked over with Gu Cao.

"Phew!"

Lowered his head and spit on the stone, watching it make a sizzling sound and boil and vaporize in the blink of an eye, Lin Luo showed a satisfied smile on his face.

"Gu Cao, quickly pour all the contents of the bamboo tube on the stones. ”

While directing Gu Cao, Lin Luo also opened a bamboo tube in his hand, looked at the small amount of water in it, gritted his teeth and poured it all on the stone that had been burned hot.

This water was distributed between him and Gu Cao today, and Lin Luo did not choose to drink it, but put it away and used it for this important matter.

Phew!

At the moment when the water was poured on the stone, the sound of boiling suddenly sounded.

Along with it, there was also a rising scorching steam, which made Lin Luo involuntarily take two steps back.

Phew!

Immediately, another more violent boiling sound sounded.

Gu Cao also opened the bamboo tube in his hand, followed Lin Luo's example, and poured all the orange-yellow liquid inside onto the stone.

"I'll go!"

Smelling the smell of urine, Lin Luo screamed, and immediately covered his nose and took three or four steps back again.

That's right, what Lin Luo asked Gu Cao to collect yesterday was urine.

No way, in the hot summer season, water is equivalent to life.

For a little water, the warriors of the tribe can fight for their lives, how can they give him water to carry out experiments on thermal expansion and cold contraction just by his words.

Therefore, Lin Luo, who is very self-aware, did not waste his efforts in vain, but put his idea on urine.

Anyway, urine is water!

That is, when it evaporates, the taste is a little worse, but the effect is no different from ordinary water.

After pouring on the little water and the urine that he had finally collected, Lin Luo suddenly stared at the stone with a nervous face.

To be honest, whether he can succeed this time or not, in fact, he has no bottom in his heart.

After all, not all rocks can crack in thermal expansion and cold contraction, and Lin Luo's knowledge in this area is also extremely lacking.

Not to mention knowing what kind of rock is easy to collapse in thermal expansion and cold contraction, he can't even identify the type of rock in front of him.

Therefore, this time he also has a huge gambling component.

Under Lin Luo's nervous gaze, in just two or three seconds, the boiling sound and rising water vapor gradually disappeared, but the rocks didn't look too obvious to change.

There is still too little water, not enough at all!

Seeing the situation in front of him, Lin Luo also quickly realized the problem.

Anxiously turned his head left and right to look, and seeing that he really couldn't find any other liquid, Lin Luo gritted his teeth and directly ripped off the thatched skirt on his waist.

"Gucao, pee on the rocks. ”

At the same time, Lin Luo did not forget to turn his head and call Shanggu Cao.

After spending so much time and effort, now that he was so trembling at the end, how could Lin Luo be willing to give up.

Hearing Lin Luo's words, Gu Cao didn't hesitate to tear off the thatched skirt.

But when he held his little brother in his hand and aimed at the target, he turned his head with a face full of embarrassment and said, "Luo, I can't pee." ”

"Then hard pee!"

Lin Luo's tone seemed unquestionable.

Hard urine? How do you urinate?

Lin Luo's words made Gu Cao even more embarrassed, he really didn't have any urge to urinate now.

Phew!

While Gu Cao was anxiously studying how to urinate hard urine, Lin Luo had already aimed at the rock and fired accurately, and the sound of urine boiling sounded again.

This time, in the face of the smell of urine rising again, Lin Luo didn't dare to take a step back.

He didn't have a lot of self-confidence, and he felt that with his current fourteen-year-old thin body, he could still achieve accurate hits from a range of two meters.

Feeling the surging and slightly steaming and moist breath, Lin Luo could only hold his breath as much as possible.

Even so, he had to sigh in his heart.

This is sour and refreshing, and the aftertaste is endless!

This kind of smell, this taste, this kind of experience, I am afraid he will never forget it in his life.

Crunch!

Just as Lin Luo was secretly sighing, a cracking sound kept coming from the rock.

It worked?

Hearing this voice, Lin Luo's eyes suddenly widened with excitement.
