Ancient wasteland

As drinking water, mountain spring water and well water are better than stream water, filtered by rock formations, and there are few sources of pollution.

Some mountain springs can even be drunk directly.

Of course, the quality of streams flowing from the mountains is much better than that of rivers and rivers flowing directly from the surface.

After all, it is a matter of filtering.

Jing Que gnawed on the roasted white bear meat, thinking about how to filter the stream water.

The meat quality of the white bear beast is a bit old, but the barbecue people are good at it, the taste is salty, and it is very chewy.

It's a bit like the dried yak meat that Jing Que had eaten on the grassland before.

The barbecue was delicious, and Jing Zhu was thinking about filtering it while eating, and finished the barbecue without knowing it.

Seeing that he had finished eating the meat in his hands, the priest was very pleased, and handed him the barbecued meat that was placed on the leaves next to him, "Eat more."

Only then did Jing Que come back to his senses, feeling that his stomach was full.

She shook her head and wanted to refuse, but just as she opened her mouth, she couldn't help hiccupping, "Uh~"

He was a little embarrassed, lowered his head, took a leaf from the side, dipped it in water, and wiped the oil stains on his hands.

Hearing Shan's voice full of worry, "Jing, you eat so little, you don't eat as much meat as the children in the tribe!

How can you get strong by eating so little meat. "

Jing Que, "...uh, I'm already full."

He is indeed not as edible as grass, but that is because the grass is too edible, not because he eats less.

The piece of barbecue that Gangshan gave him weighed about 2 catties, not 2 catties of raw meat, but 2 catties after roasting and shrinking!

The real deal is 2 catties, without water at all, it is still white bear meat, the meat itself is tight and very filling.

He usually couldn't finish eating so much, just now he was thinking about something, and he didn't pay attention to eating all of it, and now his stomach is full of panic.

It's grass, there are no elders to take care of them in the tribe, the living conditions are too poor, and they are used to starving.

I never know if I will finish this meal or if there will be another meal, and I am forced to develop the habit of overeating.

After the white bear was carried back, he was assigned to the tribe. Cao Cao had no salt in his hands, and was worried that the meat would rot and could not be preserved.

I just want to roast all the meat in my hand and eat it.

That's about ten catties of white bear meat, even if it shrinks after roasting, it still has about eight catties.

Rolling his eyes, he stuffed it into his mouth desperately.

Jing Que was terrified to see it, afraid that he would choke himself, so he hurriedly stopped him from continuing to eat, took out a Xiaoshi pill and fed it.

After knowing the reason, I felt very sad again.

Think about it for a while, and exchange all the meat left over from his gnawing with salt.

Cao Cao was quite embarrassed, so he brought water to help him, mowed the grass and built the roof of the thatched house, and was very diligent.

After eating too much, Jing Zhu stood up, "I'll go to the stream to have a look."

The priest thought about it for a while, "Ask Bei to accompany you."

During the day, he and Bei shared a hut, and Bei did most of the heavy work.

He just stood by and helped, and he was exhausted. Even though he was a fighter, it might not be easy.

The priest was worried that something would happen to him, Jing Que smiled, "Find grass to accompany me."

Dadong is a collective dormitory for the tribe to accommodate children and the elderly, and the environment is still as bad as ever.

Standing at the entrance of the cave, he could smell a stench, and even the air felt unclean. Jing Que frowned and covered his nose.

When he frees up his hand, he has to clean up this place!

Grass and Water are huddled in the corner, whispering, about the Xiaoshi pill that Jing Que gave him, which is very delicious.

If you don't believe the water, it's a pill, and the medicine is not good, like the neem water they just drank.

It's very bad to drink. After drinking it, the tongue is not obedient.

And the stomach still hurts, fortunately it only hurts for a short while, they are very able to bear the pain, just bear it.

Seeing Jing Yu appearing at the entrance of the cave, the two quickly ran out of the cave.

With sparkling eyes, she looked at Jing Que, "Jing, are you looking for us?"

According to Jing Que, the two children are about seven or eight years old, but because Ye is so big, they are only 15 years old.

The actual age should be younger. When Jing Que first arrived, he was skinny and frighteningly thin.

In the past two days, I have eaten well, raised a little meat, and washed my body clean.

It is estimated that there is no animal skin, and the leaves are wrapped around the waist, which looks quite energetic.

Jing Zhu nodded, "Come with me to the stream."

Leading the grass and water, Jing Qu walked up the stream.

The streams are deep and shallow, and the paths are narrow and wide. The widest part is about five meters, which should be due to the water season.

During the dry season, the water volume of the stream will definitely decrease, but it should not dry up, which is enough for the minimum water consumption of the tribe.

Following the stream, before walking far, Jing Que stopped at the edge of the tribe, "This place is very good."

The stream splits in two in front, and the split stream flows over the sloping stones beside it.

Then it falls to the ground, close to the side of the road, and you can reach it with your hand.

The distance to flow over the stone is about three meters, which is enough for him to filter the stream on the spot.

After confirming the location, Jing Zhu led the two children back while thinking about how to start the construction.

When the tribe arrived, Jing Qu called to Cao Cao, "Do me a favor."

Cao nodded vigorously, "Okay!"

Jing Que pointed to the poop next to him, "You bring water and clean up the tribe, and I'll give you the animal skin."

Cao's eyes lit up, "Really?!"

Jing Yu nodded, "Of course."

Cao squatted down immediately, trying to pick up the pile of poop with his hands.

Jing Que hurriedly pulled him up and reprimanded him with a dark face, "Don't touch it with your hands, ask me for tools tomorrow."

After driving the grass and water back to the cave to sleep, Jing Que went back to the cave and found four dry wood chips of suitable length.

Use a bone knife to cut off the sticky barbs on it, and then use a stone to polish it slightly to make two simple clips.

Then weave a small basket with thatch, hang the handle, and prepare for the grass and water tomorrow.

After finishing his work, his stomach didn't feel full for a long time, so he packed up and prepared to go to bed.

The next morning, before Ye had woken up, Jing Que drank the broth in the sacrificial cave and gave Cao the clip and straw basket.

Instruct them carefully to throw the cleaned poop into the toilet and flush it down with water without leaving any traces.

Waiting for Cao to nod his little head to show that he understands, and then he takes Bei out to the place he was looking forward to yesterday.

Jing Que stood on the rock and rowed with Bei Bi, "From here."

He pointed to the uppermost part of the boulder and drew down, "If we get here, we need to dig a tunnel.

The width should be about 50cm, which is about that wide, and the depth should be 20cm. If you find it difficult, you can reduce it.

In the middle, there are three recessed places at both ends, which are used to clamp wood chips. They are here, here and here, and the recesses are about this long. "

What he planned was to use the filtered water to wash vegetables and cook rice.

Usually, you need to treat animal skins with water and take a bath, so go to the old position and keep it a little lower.

This is both convenient and hygienic.

Bei squinted to see where the water flowed on the stone, remembering what he said, "Okay."

Jing Qu smiled, "Then you do your work first, I'll go back and prepare charcoal."

The simple filter device is roughly divided into four layers. The top is pebbles, which can filter out large garbage impurities such as dead branches and leaves.

This is followed by coarse sand, which filters out dirt and small debris including bug eggs.

These two kinds can be seen everywhere in the creek, and can be directly used as materials!

On the third floor, Jing Que plans to put charcoal, which is charcoal made from green branches.

Charcoal has good adsorption properties and is very suitable for adsorbing small impurities.

It was burnt from a sacred tree like Qingshu, and it was even more outstanding. Jing Zhu felt that it must be much better than the red radish charcoal and silver bone charcoal in the legend.

The quality is good, and the adsorption is definitely better. Jingzhu is looking forward to the effect.
