Chapter 460 Salt Soil

Ayin said, "Then what about yours?"

Li Junge smiled proudly: "The handle hasn't been installed yet. I made it multi-purpose. One side is sawtooth, which keeps the same hardness; the other side is the cutting edge. The bottom third is a large V flat grinder for cutting. The front two-thirds is a re-opened edge line, the angle is blunter than the rear, and it is used for chopping."

A Yin said with a smile: "Just talk and don't practice fake moves! I will heat up the strange crab here, you quickly put on the handle, and we will go to test the knife after eating!"

Li Junge ran back again and picked a hardwood blade that was 20 centimeters smaller, but the handle was more than [-] centimeters long. One was to keep the center of gravity behind and take care of the cutting, and the other was to keep it sharp when chopping. Can be held with both hands.

Saw the back of the knife from the middle of the handle, put the blade in, try to match the feel, and make some fine-tuning. After reaching perfection, remove the blade, measure the position of the hole on the outside of the handle, and start to use the pressure drill to give The handle is punched.

This is why the width of the drill bit on one side is exactly the same as the hole diameter of the blade, so that the knife can be completely fitted after it is installed, and the blade of the handle is firmly fixed.

Drill the hole, put the blade in and adjust the position, scrape out three cylindrical bamboo nails, fix the blade and the handle firmly, and then use a knife to flatten the bamboo nails, and the long knife is assembled.

After eating, Li Junge put a scabbard on the long knife with bark, touched the handle and said, "Precious knife, precious knife, how can this sheath be suitable for you? I will change it for you when I have a chance to hunt wild animals." clothes."

A Yin couldn't stop laughing, and said: "In a blink of an eye, I returned the precious sword, and it was not modified by a hand saw..."

Li Junge rolled his eyes and said: "I don't blame you if you don't understand. The hand saw can be changed into this way. In addition to craftsmanship, there is also luck. It's really a spirit of ancestors. With these two knives, we can walk sideways on this island Already!"

A Yin laughed loudly: "There are only a few of us on this island, you can walk sideways without holding a knife, it won't hinder anyone..."

Forget it, talking about swords and swords with girls is like a blind man lighting a lamp in vain. When the two entered a bamboo forest, Li Junge said, "Let's start small."

I chose a bamboo as thick as an arm, and chopped it down at an angle of 45 degrees with a knife in both hands. Li Junge hardly felt that the bamboo was cut into two pieces.

Li Junge checked the edge of the knife and said, "It's too easy, the next one."

After cutting all the way down like this, A Yin said: "Forget it, forget it, you are amazing! Let's drag the bamboo back, now that we have a knife, we can make some fine bamboo wares."

Li Junge looked at a large bamboo forest and felt that it was not enjoyable, but he thought that the more he cut, the more work he would do, and the oil had not been boiled there, so he agreed with A Yin and picked the bamboo off the branches with a sharp spoon. Carried a bundle back.

Back at the camp, Li Junge asked A Yin: "How many buckets of water have we poured on the mud ball?"

A Yin said: "I have poured seven or eight buckets."

Li Junge said: "I poured about ten buckets, which is twenty buckets. One bucket is ten catties, which is two hundred catties of seawater. Hahaha, there are four catties of salt in the mud ball."

A Yin said: "Ah, this method is really fast!"

Li Junge said with a smile: "This is the wisdom of the ancestors of ancient Shu. What is this? At Ziliujing, the brine under the underground rock layer has to be taken out. That is even better. How do you think they know that there is brine hundreds of meters underground? ? It's incredible..."

The two chatted and worked. A new pot of oil was boiled out, and Li Junge poured it into the bamboo tube again, and the first bamboo tube was filled.

Li Junge picked it up: "Hahaha, here is five catties of oil."

Then he looked at the bamboo tube that had been tempered with a knife, and said to A Yin: "Is that coconut oil still edible? There are two or three catties there!"

Ayin said: "It doesn't matter if you can't eat it, if you can't eat it, leave it to me to make soap!"

Throwing a few thick bamboo poles to bake on the bamboo leaf grooves on both sides of the dragon kiln, Li Junge began to use a knife and wedge to cut bamboo slices to get the bamboo skin.

This time the efficiency is much higher, and the obtained bamboo threads are all the width of the little finger, which is very uniform.

Li Junge nodded in satisfaction: "This is my Lijiagou's craftsmanship!"

A Yin laughed and said, "This is the way that if a worker wants to do a good job, he must first sharpen his weapon, right?"

Li Junge started to weave the baskets, and said, "This pair of baskets looks almost the same as that made by the bamboo strip maker."

It took two hours to re-weave a new pair of baskets, completely in the style of Lijiagou.

Li Junge carried the baskets to the water tank, spread plantain leaves in one, took out all the crude coconut oil on the surface of the water tank and put them in, then poured the remaining shredded coconut in the water tank into another new basket.

Spread plantain leaves on the mud stalks behind the dragon kiln clay balls. Li Junge took the shredded coconut into the stream, washed them clean, squeezed out the water, and spread a layer on the dragon kiln.

A Yin boiled another pot of oil, Li Junge filled it with oil, freed up the pot to boil the second pot, then dug a hole in the ground, stepped on the bottom, and buried more than half of the bucket in the soil. Then put stone slabs in the barrel to make a nest.

I saw a two-meter-long piece of hard wood with the thickness of a thigh, split the middle with a knife, and made a wooden pestle, and then roasted the chopped wood block with the wooden pestle.

After finishing these, Li Junge found four more straight tree trunks, spread them on the ground to form a square frame, dug shallow trenches to put the trunks in, and made a square border.

Pull out the weeds in the square border and trample the ground firmly.

Ayin watched Li Junge busy, and asked, "Er Pi, what are you doing here?"

Li Junge said with a smile: "This method comes from "Tiangong Kaiwu". It is called the method of pouring ash. It can extract sea salt from saline soil. It is also a method used by salt households in Zhejiang in the Ming Dynasty."

After finishing all this, Li Junge told Ayin to stop watering the mud balls, and then he went to take out the vacated basket and dig out the remaining forty coconut meat.

With a machete, it's fast. After a while, the coconuts are peeled out and chopped in half.

A Yin said: "Erpi, I've finished eating the strange crabs today, and I'll have to find something to eat tomorrow, otherwise, there will only be saponin rice left to eat."

Li Junge said with a smile: "That thing is not for eating. You are usually asked to use the saponins seeds and saponins shells separately, just for the seeds to come in handy these two days."

After finishing speaking, he slapped his mouth and said: "I'll go and see the trap later, maybe it's working? It really doesn't work, seaweed and coconut will survive tomorrow, and I'll have everything when I get home."

At this time, a new pot of oil came out, and Li Junge continued to fill the two large bamboo tubes with oil, which was ten catties.

Li Junge said: "The remaining forty or so coconuts will be able to produce the same number tomorrow, hahaha, there will be no worries about running out of oil for these dozens of days."

After eating, Li Junge peeled out the saponins seeds and soaked them in a washbasin.

Then start pounding the mud balls.

Crush the mud balls into mud powder, and ask A Yin to put the mud powder on the Shau Kei, and spread it evenly in the square furrow.

A layer of salt soil was spread five centimeters thick in the square furrow, and Li Junge asked Ayin to spread the sifted plant ash on it, and continued refining the oil himself.

Ayin spread another five centimeter layer of plant ashes on the salt soil. Li Junge asked Ayin to take over, and he would start spraying seawater on the plant ashes.

After spraying a bucket of seawater down, Li Junge felt that his tongue was no longer his own, so he quickly rinsed his mouth, and then flattened the ashes with a bamboo shovel.

After finishing these, Li Junge started to burn the shells that A Yin had collected on the beach.

The two buckets on the other side first pour the seaweed ash into half a bucket, fill up the stream water and start stirring.

The big thin-eyed basket for soaking leaves in the stream was useless, so Li Junge disassembled it, wove a funnel out of bamboo silk, put shredded coconut palm silk on it, and filtered the water soaked in seaweed ash.

This is the sodium carbonate solution.

After the shells are fired, the main component of the shells is calcium carbonate, which turns into calcium hydroxide after firing, which is quicklime.

Pound the quicklime in a pestle, sieve out the fine powder and stir it with stream water. In addition to steaming, a calcium hydroxide solution is obtained.

Separate half of the seaweed ash solution and the shell ash solution and stir them together. In addition to generating a large amount of calcium carbonate precipitate, the remaining liquid becomes a sodium hydroxide solution.

After tossing back and forth between two barrels, an empty water tank, a brown silk funnel, and a pile of ashes, Li Junge finally got sodium hydroxide solution, sodium carbonate solution, these two barrels of important chemicals, plus a pile of quicklime to mix mortar.

After finishing these, Ayin's coconut oil was boiled again, and Li Junge poured the oil into the big bamboo tube again, and the two walked hand in hand, taking advantage of the night to see the scenery of the beach and play with the sea water.

These two episodes in the live broadcast room made several guests blow up.

Bell: "Jungle's operation is against the sky! He and Ingris actually extracted oil from coconuts!"

Lune: "Yes, this one is almost unthinkable, and it didn't take them much effort."

Nian: "Uh, this is the daily operation of our Thai family, okay? My mother also does this. Coconut oil and tapioca flour are important agricultural products in our Thailand. Fully mature coconut meat contains 30.00% oil, so it is easy to make come out..."

Bell: "Uh, well, what about the knives? I transformed the hand saw into knives, and there are still two! This involves two processes of tempering and oil quenching. Has this Jungle worked in a steel factory before?"

Luen: "From the way he quenches the oil, I feel that this seems to be the craftsmanship of knife craftsmen."

Nian: "Not just the knife, he got all the screws on the hand saw, a chisel and a pressure drill."

Bell: "And the knife is very sharp and powerful. You should pay attention to the video of him chopping bamboo. When other teams are still burning fire at the bottom of the bamboo pole to obtain building materials, the Chinese team has completed a qualitative leap. As long as Jungle is willing, he can use it one day. All the bamboo needed by the eight teams within [-] days can be cut in less time!"

Lu En: "There are also mud balls that thicken seawater. Our program team specifically consulted physics professors at the university about this. They were also very surprised by this method. The scientific principle is to use the loose channels in the mud balls to increase evaporation. The area makes the water vapor quickly dissipate. This effect is astonishing, and we speculate that before they stopped watering, the two mud ball pyramids already contained no less than three kilograms of coarse salt!"

Bell: "Uh, in fact, for survival, the intake of salt can come from animals and plants. If you persist for fifty days, it's actually not particularly important."
