Prehistoric Survival Records

Rigg hadn't slept well all night with his thoughts on the pool.

Although the problem should not be big in theory, in fact he is always worried, whether the mud wall will crack, whether the foundation will collapse, what if someone destroys it, and his head is full of confusion all night. Thinking about these things, he was restless in his sleep, and kicked Charlie out of bed several times a night.

Every time Charlie was kicked out to blow the cold wind when he was sound asleep, it was very inexplicable. Fortunately, he had a big heart, and quickly rolled back with his little butt tucked in. By the way, he helped the other three pick up the crooked animal skins, and continued on his own. Hoo hoo.

The next day, nothing happened to Charlie, but Rigg caught a cold.

Rieger kept sneezing when he got up, and Quinn and Laika were going to hunt, so they could only tell him to stay in the cave and not to run around today, and let Charlie watch him by the way.

But Charlie, a little friend, couldn't stand Rieger's flickering and flickering, and soon threw his father's orders out of the blue.

It's impossible not to go out, today is also a day of freedom!

Rigg was obsessed with his sink, and he was talking to Charlie about his great cause of water purification all the way, occasionally sneezing a few times.

Fortunately, God didn't mean to embarrass Lige. After being baked by the fire yesterday and dried naturally overnight, at least in appearance, the pool looks no different from the simple self-made pool in the farmhouse.

Gal looked at the fruits of his labor yesterday with a face full of disbelief, such a clean, smooth, and solid thing was born from his own hands?

"Could it be that I have also been blessed by the beast god?" Gal looked at his hands and said to himself.

Billy even patted his whole body by the edge of the pool to feel it.

When the pond was just built yesterday, the mud was soft. Whenever he poked a hole, his brother would give him a headbutt if he dared to touch it, and then carefully filled the hole.

Billy was banned by Rigg and his brother when he wanted to touch it yesterday. Now that the mud is completely dry and the whole pool is very strong, it is finally not afraid of breaking the pool. Emma has to touch something worthwhile.

Rigg let Billy touch it for a while and called him down. There was still work to do in a while, and today's event was the highlight.

Besides, Rigg is really afraid that Billy, a big man, will damage the pool. Although the mud looks solid after it dries out, there is no glue and joint agent added. Well, his filtration system hasn't been tested yet.

The principle of making a filter tank is the same as that of making a small filter, except that the filter tank is bulky and consumes more filter elements.

Fortunately, there is no lack of anything in Rige. In this undeveloped prehistory, such basic things can be whatever you want, and you can have as much as you want, but you can build it with strength and don't feel bad.

The bottom of the pool is evenly covered with freshly burned charcoal. The charcoal is loose and porous, and has a particularly strong adsorption capacity, and this adsorption capacity is a physical property without any toxic effects, let alone secondary pollution. The most important part of the system.

Cover the laid charcoal with a layer of clean and fine river sand, the thickness of which is about twice that of the charcoal, but there is no ruler or anything at hand. Just check it visually. Because the river sand is fine and dense, it can filter out most of the liquid. Impurities are the backbone of the filtration system.

On the fine sand layer, Rieger arranged another layer of pebbles. These pebbles can keep larger solid impurities in the liquid, such as leaves, grass roots, plankton, etc., on the pebble layer to prevent these things from entering In the lower layer of fine sand.

After laying the pebbles, the work could have been done, but because of Rigg's own obsessive-compulsive disorder, he instructed Billy to move some stones bigger than his fist, wash them in the river water, and press them on the pebbles.

In this way, a very simple, but quite advanced filter tank for this world is ready.

This thing should be more than enough to filter raw water, but the purpose of Lige is not to improve the quality of salt. It seems a bit overkill to pour the dissolved salt water into this thing. In fact, a layer of charcoal particles is enough That's enough, but if you're overqualified, let's be overqualified, I'm rich and powerful, Rigg laughed wildly with his hands on his hips.

A large pile of table salt was melted in the brothers' stone pot and poured into the filter tank.

At this time, I felt that there was trouble. There were two strong laborers and a large pool, but there was only one stone pot in the container for melting salt. One trip had to go to the river to fetch water. Lige looked at the side and almost piled up like a hill. The salt, which has to be melted in what year and month.

If you want to do a good job, you must first sharpen your tools. The old Chinese saying is not good at me. It seems that after this job is done, I have to find a way to improve the daily necessities of the tribe. Otherwise, it would be too embarrassing to do something up.

Fortunately, Billy walked fast, and it didn't take too much time to exchange with Gal.

Soon, the pool will be full. . .full?Yes full!

Rigg patted himself on the forehead with a groan, what a bad memory he is, he forgot to make a hole for the pool, if the salt water can't flow out, it means the pool is full.

Fortunately, it was easy to make a hole on site. Rieg drew a circle the size of a finger under the filter tank near the foundation. Gal rubbed his sweat and used the sharp point of a stone knife to dig out a little bit. It didn't take much effort. A finger-sized circle The hole opened.

Along with the mud and sand that had just been dug out outside the cave, what flowed out was a liquid that was very clear to the naked eye.

Lige hurriedly beckoned to bring the stone pot. This is the salt water that has been filtered layer by layer, which is precious, and seeing that the salt water is as clear as the mineral water he drank in the previous life, the taste should be greatly improved.

Thinking of this, Rieg dipped his finger in a little salt water and put it in his mouth.

!

The pure saltiness is transmitted to every nerve through the taste buds, absolutely!

This is the taste of good salt!

He hurriedly called Galbilli, who was waiting eagerly, to let them try it too.

After Gal tasted it, he was astonished. He couldn't believe it. He shook his hands like Parkinson and asked Rigg for confirmation.

"This, this, is this the smell of salt?"

Billy took a big sip and was dumbfounded after drinking it: "Why isn't this sour or bitter at all?"

Emma, ​​you are a big man, and you are not afraid of drinking such a big mouthful.

Rieger explained to them: "The taste of salt is neither sour nor bitter. It tastes sour and bitter because the salt stone contains not only salt, but also other sour and bitter things in it. The filtration system we made filters the brine once, greatly reducing the impurity content in the brine, and the taste of the salt becomes better.”

Gall suddenly realized: "It turns out that's the case. No wonder the original salt rock powder often looks so disgusting. It's also because there are more other things in it."

Lige nodded with his little hands behind his back: "That's right, you're right. The salt stone powder is so unpalatable because it contains a lot of stone powder and large particles of impurities. Before, I initially removed the impurities on the large surface. It is removed, but some relatively small impurities still remain in the salt, which requires further filtration, which is the filter tank we built.”

He also explained: "In fact, the filter pool cannot completely filter out all impurities, but the current level of technology can only achieve this."

After speaking, Lige sighed like a little adult, as if he was not particularly satisfied with the result.

Gal didn't understand technology or filtration. He only knew that he listened to Rigg's instructions and tinkered with a very remarkable thing. As long as the salt water was poured out of the small hole, the taste would change. It tastes better than ever.

Originally, he thought that the salt produced by Lige for the first time was the best salt in the world. Unexpectedly, he did not expect that such delicious salt could be even more delicious.

The most important thing is that he and his younger brother also participated in this matter, which means that salt can make it more delicious, and he and his younger brother are also major contributors to it!

Gal's vanity was deeply satisfied, and he couldn't wait to say: "This is a big event in the tribe, and the patriarch and other tribesmen should be invited to take a look!"

Yes, call the patriarch and other people to see their results, and tell some of them to secretly laugh at them for accompanying a brat, this is an ordinary brat, this is a disciple of the Beast God, He followed the Beast God's disciple, and rounded up he was also the Beast God's disciple, let those who chew their tongues be envious.

Billy didn't go as far as Gal thought, but he also agreed that this was a big deal, and he needed to ask the patriarch to take a look.

Rieger didn't have any objections. This matter was originally done for the tribe. Now that the tribe has a lot of salt, the idle population has not been fully utilized.

You can build several more filter pools, some are used to filter salt water, and some are used to filter daily drinking water.

The consumption of charcoal in this way will not be small. The first kiln has successfully fired charcoal, and he knows it well. In the future, the charcoal burning will have to be handed over to the tribe, and he has to develop other things as soon as possible.

Through the charcoal burning this time, he found that the brick burning must also be put on the agenda, and the tribe couldn't keep using the disposable charcoal kiln.

There are not enough containers in the tribe. Since we need to filter salt water and drinking water, we need to use a lot of buckets, basins, and so on.

Besides, the filtered salt water also needs to be boiled dry and re-decomposed into table salt, and the big guy still needs a pot to eat, so where can I really requisition it for him?

Thinking of the endless busy days afterwards, Lige's eyes darkened, and he deeply felt that his trip to prehistoric times was not for enjoying the blessings, but purely exporting labor services after a few centuries.

The author has something to say: A bird made a nest on the flower stand outside the windowsill of my house at some point. When I saw it today, there was already an egg in the nest. I hope the bird can hatch smoothly.

Today, I wish the motherland a happy birthday in advance! ! !
