I'm bad and I'm hitting a wall, primitive life requires hard work

After doing this, Nishi Ichiki walked deeper into the cave and found four pillars that were closely connected to each other. He fixed the four corners of the linen cloth to these pillars with animal skin strips.

Since the column is pointed at the top and thick at the bottom, by properly adjusting the size of the circle made of the animal skin strips, the linen cloth can be hung on it securely and will not slip off easily.

At this moment.

The tribesmen in the tribe all widened their eyes, and no one spoke. Their gazes were like being attracted by a magnet, always following Xi Yiqi's every move, watching her busying back and forth.

Nishi Ichiki directed others to carefully place the small stone pot in the center of the hanging linen and carefully tested its load-bearing capacity.

Seeing that the linen was as stable as she expected and did not slide down, a satisfied smile appeared on her face, and she took the basket full of various materials and leaves.

Then, she began to make the most critical part of the simple water purifier in an orderly manner - the filter layer.

First, she spread a thick layer of grass and leaves on the bottom layer of linen, then evenly sprinkled a layer of crushed stones, and then covered it with a layer of fine sand.

After completing these steps, she took out the charcoal ash that had been ground into powder and gently spread it on the sand layer to form a thin layer of charcoal.

Next, she covered it with a second layer of sand, and finally gently placed the small pebbles on the top.

This series of actions left the tribe members dumbfounded.

Looking at the simple water purification device in the shape of a funnel, Nishi Ichiki patted the dust off his hands and smiled with satisfaction: "Okay, it's done!"

what?

Is this done?

The tribesmen were still in a daze and had not yet come to their senses.

They looked at each other in bewilderment and couldn't help wondering: Can this weird thing really make muddy water clean?

Curiosity and expectation were intertwined in their eyes, but there was also a hint of doubt.

Wu Yu walked around the device with great interest. After taking a closer look, he asked, "Is this what you call 'filtering'?"

Nishi Ichisu shook his head slightly.

“It’s just a simple water purification tool that can start filtering right away.”

Then, she turned to Yanluo and Arthur: "Uncle Yanluo, Uncle Arthur, could you please help me move the stone jar over here? Let's start filtering now."

Without a word, the two men acted quickly and soon moved the large stone jar filled with muddy water steadily to the side of the filter device.

They couldn't wait to see how this strange thing filtered dirty water into clean water.

Nishi Ichisu then asked two people to move the small stone pot over and place it directly below the hemp water filter.

After everything was ready, Nishi Ichiqi smiled knowingly as he looked at everyone's expectant eyes.

Next up!

that is!

It's time to witness a miracle!

I saw Xi Yiqi pick up the stone bowl, scoop up several large bowls of turbid stream water, and slowly pour it over the pebbles.

Seeing this scene, everyone was somewhat puzzled but still stared at it patiently.

Since the linen was not transparent, Nishi Ichisu could not directly see what was going on inside and could only wait patiently.

Time goes by every second...

"Yes, yes! It's really clean water!"

"Oh my God!"

"Amazing!"

Shouts of surprise echoed in the cave.

Everyone gathered around the water purification device, staring closely at every drop of water dripping from the linen cloth.

Clear water drops slowly seep out...

One drop, two drops, three drops...

After a while, a small bowl of food accumulated in the stone pot.

The water looked clean and clear, a far cry from its previous turbid appearance.

Yan Luo and Arthur both widened their eyes and looked at this magical scene in disbelief.

Wu Yu looked at Xi Yiqi deeply. This girl's inheritance was indeed very special and could bring such a miracle.

Nishi Ichisu looked at the clear water and felt relieved.

The effort paid off and luckily I succeeded.

"Wu Xiqi, can this be drunk directly?" Arthur asked Wu Xiqi curiously, pointing at the water in the small stone pot.

Xi Xi smiled and replied, "Of course."

After getting a positive answer, Arthur carefully scooped up some water with the stone bowl, gently put it in his mouth and took a small sip!

After just one taste, he was amazed by the taste of the water and drank all the water in the stone bowl.

"It tastes really good! There is no strange taste at all." The water in my hand was as clear as a mirror, without any impurities. It tasted a little sweet, and the taste was many times better than the stream water I drank before!

Hearing Arthur's praise, Nishi Ichisu also scooped up some and tasted it. It was indeed sweet and refreshing.

Suddenly, she felt refreshed both physically and mentally, as if all her fatigue and depression had dissipated at this moment.

At this time, the entire system was functioning smoothly, because endless power was flowing towards him from the tribesmen around him. The feeling of being surrounded by power made him feel extremely comfortable, and he even wanted to shut down the computer and take a break.

It's been a long time since I last felt this way...

Compared with fish traps and earthen stoves, the status of water purification filters in Xi Yiqi's heart has skyrocketed and become the number one on the list.

The tribesmen couldn't wait to take the stone bowls, scoop up the remaining water, and each took a sip.

"Hmm, Sister Xixi, this water is really delicious. It's sweet~" After taking a sip, Yan Ya happily jumped around the water purifier like a little rabbit.

Unfortunately, the purification speed of this water filter is too slow and is far from meeting the drinking water needs of dozens of people in the tribe.

Obviously, Yan Luo was also aware of this problem. He frowned and said, "Wu Xiqi, how about Arthur and I go to the stream to fetch some water?"

Nishi Ichisu shook her head, her eyes falling on the water purifier that was filtering.

"Don't worry, once this tank of water is filtered, we can pour it into the stone pot we usually use to cook meat. The tribe doesn't have any extra containers to hold this clean water."

Yan Luo was stunned for a moment, then nodded, thinking that Xiqi was right, there were indeed no more stone pots in the tribe.

He decided secretly in his heart that he would have to polish another huge stone vat after the rainy season.

It has to be said that Xi Yiqi's idea coincides with Yanluo's, but she is considering finding other methods, such as using a clay jar.

Although we don't know how this group of primitive people polished this huge stone pot, it must have been extremely time-consuming and laborious.

Thinking of the clay jar that Wu Yu brought back from the Washa tribe, Xi Yiqi thought secretly: This trip to the Washa tribe is a must.

Nishi Ichiki came back to his senses and waited quietly at the water purifier for a while. Then he scooped a small stone bowl of water and handed it to Nimei, asking her to boil it for Ste to drink.

Nimei asked with a puzzled look on her face: "Xixi, why do we have to boil it? Didn't you say that this water can be drunk directly?"

Nishi Ichiki was unable to explain to her the complex concept of microorganisms. The people in the tribe drank dirty stream water all year round, and the bacteria remaining in the filtered water might not be a big deal to them.

But for the sick Ster, it is better to be cautious.

"Ster has severe diarrhea now. He is dehydrated and very weak. It is better to boil water for him to drink. If anyone in the tribe gets sick in the future, try to boil water for them to drink."

"Okay." Ni Mei agreed and turned to boil water.

After working for several hours on an empty stomach, Nishi Ichiki finally had time to catch his breath.

She dragged her exhausted body, found an empty space and sat down slowly.

Watching the water droplets falling, her eyes gradually became blurry, and she soon fell asleep...

Yanya turned her head and saw Xi Yiqi lying on the ground. Her little face turned pale instantly and she cried out in fear: "Wow, Sister Xi Yiqi, Sister Xi Yiqi is sick."

When the tribesmen heard her crying voice, they were startled and turned away quickly.

Their next witch, Xi Xi, was lying in the corner in a strange posture.

!!!

"Not good!"

"Wu! Wu! Oh no, Wu Xiqi fainted."

Wu Yu was squatting aside, studying the "water purification device" carefully, when he was suddenly dragged to a corner by his tribesmen.

He looked at Nishi Ichiki who was lying on the ground. He was so shocked that he didn't have time to speak. He quickly squatted down to check on her condition.

Just check this.

……

Wu Yu actually laughed out loud, and his elegant and clear voice echoed in the cave.

The tribesmen who dared not breathe looked at Wu Yu in surprise, not understanding why he could laugh even though Wu Xiqi had fainted?

"Wu, Wu Xiqi, what happened?"

Wu Yu took a piece of dry animal skin from the side and gently covered Xi Yiqi with it to cover her twisted posture.

Just as he was about to explain, everyone heard a deafening snoring sound, sometimes high and sometimes low, coming from the ground.

Everyone's eyes were focused on the source of the sound, and the entire cave suddenly fell silent...
