Chapter XII

Forestry turned to look at Yuki.

Looking at her anxious look, he spoke.

“Don’t be in such a hurry, I still need some time to wait for my good news.”

“None of them are bad, just drink unclean water, and it will be fine in a few days.”

Forestry calmed Yuki a little.

Then looked down at Sakura.

Forestry plays with Sakura’s cat ears.

The fluffy cat’s ears keep swinging back and forth to avoid the touch of the forest.

Sakura also shakes her head from time to time, but she still can’t escape the clutches of forestry.

In the end, Sakura could only cover her ears with her hands and ran behind Yuki.

Looking at forestry shyly… (?ˇ?ˇ?) …。

Forestry rubbed his palms endlessly.

Then he spoke: “Sakura, you are here to help Yuki take care of the two of them, I will continue to go about my affairs, and today I should be able to solve the problem of drinking water in the tribe.” ”

After speaking, under the eyes of Yuki and Sakura, Forestry walked out of the cave.

After Forestry left, Sakura looked up at Yuki and said, “Yuki, I believe in karma, he said that if there is a way, it will definitely be solved.” ”

“Well, I trust him too” Hearing Sakura’s words, Yuki replied softly, and then looked with complicated eyes to the place outside the cave, where the forestry figure disappeared.

Just by looking at the place where the bucket was placed, the forestry industry could conclude that the people in the tribe got sick after drinking unclean water.

Sakura then confirmed that Forestry was right.

And he also discovered that every time he was sick that he had never noticed was when he was about to fetch water.

This made forestry more and more mysterious in Yuki’s heart.

Fortunately, I was curious about what forestry would do to solve the problem of getting sick from drinking water in the tribe.

After the forestry came out of the cave, a relatively smooth stone was found near the cave.

The bone knife was sharpened a little on top.

Although polished out is not very sharp.

But because of the limitation of the material, the bone knife can only be sharpened like this.

After sharpening the bone knife, the forestry industry came to the bamboo forest that was previously discovered.

This time, the forestry industry selected a bamboo about the size of a wooden barrel that holds water.

Taking out the bone knife, Forestry began to laboriously start chopping bamboo.

Because the bone knife is not very sharp.

Therefore, forestry can only choose to treat the bone knife as a saw, grinding a small hole little by little.

Growing to such a huge bamboo, his hardness is also much stronger than that of bamboo on the earth.

Forestry chopped and cut the bamboo, and it took a lot of effort to cut down this bamboo.

After working for more than half an hour, the bamboo tens of meters high finally fell in front of the forestry.

Even the forestry that had been strengthened by the pill was exhausted and panting.

After a short rest, forestry began to cut bamboo knots one by one on the bamboo tens of meters above.

Forestry cut three bamboo knots that resemble buckets.

A layer of bamboo grows inside each bamboo segment, closing and dividing each bamboo joint.

When the forestry is cut down, a layer of bamboo is deliberately left at the bottom.

At that time, just drill a few small holes in it, and water can leak out.

After working for more than two hours, the forestry industry finally cut all three bamboo knots.

Looking at the bone knife in his hand, Forestry sighed and said.

“Alas, how good it would be if there was an iron knife, you must build iron tools in the future, otherwise, you will do everything with half the effort.”

Holding three bamboo knots, Forestry walked out of the bamboo forest and came to the charcoal and pebbles collected earlier.

After putting down the three bamboo knots, Forestry collected a pile of fine sand and gravel in a clearing on one side.

After preparing the charcoal, stones, and sand, Forestry sat on the ground and began to make a water purification device.

Forestry first took a bone knife and carved some small holes for leaking water at the bottom of each bamboo knot.

The forestry then placed a layer of charcoal at the bottom of each bamboo section.

The forestry then laid a layer of freshly collected sand on top of the charcoal.

Finally, at the top, a layer of pebbles collected by the river is placed.

This is the simplest and the only water purification device that can be made in the forestry industry in this place.

In this water purification device made by forestry, the top pebbles are used to compact the fine sand and charcoal below, and at the same time can filter out the impurities with relatively large particles in the water.

The middle layer of fine sand is used to filter the small particles of impurities in the water.

The bottom layer of charcoal can absorb a large number of toxins and colored and odorous substances in the water.

After all three water purification devices were completed, Forestry took them to the cave.

Forestry entered the cave and saw Yuki still looking at the two people on the ground worriedly.

Seeing Forestry walking in with something in his hand, he stood up eagerly and asked.

“What is this thing? With this, can the problem of everyone getting sick be solved? ”

“Yes, with this, everyone will not get sick again when drinking water in the future.” Forestry said with a little smile.

Fortunately, after hearing Forestry’s words, his eyes looked curiously at the water purification device in Forestry’s hand.

At this time, Sakura came over and asked curiously with wide eyes.

“Karma, what is it in your hand, with this everyone will not be sick?”

“This is called a water purification device, and the water will not get sick after it is filtered and then drunk.” Hayashi explained to Sakura with a smile.

After hearing Forestry’s explanation, Sakura blinked her eyes and looked at the device in the protagonist’s hand, thinking with doubts: “How can this strange water purification device keep everyone from getting sick?” ”

Seeing that the two still didn’t understand, Forestry shook his head helplessly.

Then he took the water purification device and walked towards the place where the bucket was placed in the cave.

As he walked, he said, “Follow me, I’ll teach you how to use this.” ”

The three of them came together to the place where the bucket was placed.

Forestry took an empty barrel and placed it on the ground.

Then he gestured with a water purification device.

After placing the bottom of the water purification device on top of the empty barrel, the forestry industry found that the size was just right.

The two stood aside, looking at Forestry’s movements with puzzled faces.

Forestry was seen putting two other water purification devices on the ground.

The two people are like two curious babies, squatting next to the water purification device, looking east and west.

Forestry’s eyes saw that Yuki was crouching on the ground with his back to himself.

The upturned buttocks wrapped in the animal skin skirt outline a graceful arc.

For a while, forestry even had an urge to go up and take a picture.

It’s just that now the situation is urgent and there is still business to be done.

Forestry turned around and picked up a bucket of water that had been kept back for days.

It was poured into the water purification device.

The two heard the sound of water pouring from the forestry industry, and their attention was drawn again.

I saw that the water poured in from above the water purification device slowly began to penetrate downward.

The two people watched with wide eyes, and the water in the water purification device began to slowly decrease.

After the water is poured into the water purification device, after three filtrations, it flows down several small holes at the bottom of the water purification device to the wooden barrel under the water purification device.

After all the water was filtered into the barrel, Forestry removed the water purification device and looked at the water in the bucket.

Forestry searched around and found that there were no containers around that could be used to hold water, so he simply picked up the barrel and took a sip.

The water in the bucket was inhaled, and the forestry tasted it.

Compared to the glass of water that Sakura had brought herself before.

After the filtered water, not only has the smell disappeared, but it can also taste a faint sweetness.

Yukiya learned the example of forestry and took a sip of filtered water.

At the moment of drinking, you can clearly see that there is a flash in Yuki’s eyes.

Then Yuki held the barrel and drank several sips.

At this time, the system’s prompt sounded in the ears of forestry again.

“Ding! Congratulations to the host for successfully making a water purification device, increasing the civilization of the tribe, and getting a reward: trap technique. ”
