In order to cross the vast acid rain water area, Lin Shuhang used the skin of a giant earthworm to make a simple kayak.
There are pores on the earthworm skin. In order to block these pores, Lin Shuhang made a large earthen pot with mud to boil the gum. The Mad General had participated in the process of making the pot. So this time he was familiar with mud mixing.
Under Lin Shuhang's guidance, the mud needed to make the pot was quickly mixed.
After all, the mad general is an animal. He has well-developed limbs and a simple mind. He can handle rough work, but he can never do fine work. He can only make mud on the side and start fighting, so "control"
The work of "pot" still needs Lin Shuhang himself to complete it.
Lin Shuhang, who had been lying dead for a day, could now move around normally. As long as he did not do strenuous exercise, such as running and jumping, there would be no major hindrance to his body.
Relying on the experience accumulated in the past and with the help of the crazy general, Lin Shuhang quickly made a large earthen pot out of mud.
The shape of this pot is very strange. The reason why it is called strange is that the shape of this clay pot is not the usual round shape, but square.
Yes, you heard it right, and Lin Shuhang was also right. The shape of this clay pot is indeed rectangular.
The entire clay pot cost 20 tons of soil to make. It is huge. It is 30 meters long and 10 meters wide. It looks like a giant coffin without a lid. It is very shocking.
Of course, there was a reason why the clay pot was made in this shape - Lin Shuhang planned to use this clay pot to cook bamboo in order to strengthen the hardness of the bamboo so that it could cope with the high-pressure gas released when the popping dates burst.
The length of the bamboo used to make the "gun barrel" is between 20 and 30 meters. If the pot is too small, it cannot be put in. When cooking bamboo, you cannot cook one end and not the other end, so in order to evenly cook the bamboo.
When dealing with bamboo, the pot can only be made into this shape to suit the length of the bamboo.
After making the earthen pot, the sun just set.
Fuhe Forest fell into darkness again...
The surface of the newly made clay pot is still very wet. In this case, the clay pot cannot be used directly. It must be dried in the shade, sun-dried, and then fired over charcoal fire. It can only be used when the pot body becomes hard, otherwise the clay pot will be easily damaged.
.
"That's it for today. Let's put the clay pot here to dry overnight. We can deal with those bamboos tomorrow."
"roar!"
Lin Shuhang yawned: "Okay, it's getting late, Crazy General, go to bed early. We still have a lot of work to do tomorrow, and we must maintain strong energy."
Another long dark night passed with the deafening snores of Lin Shuhang and the Crazy General...
The next morning, before the bird flew on the branch, Lin Shuhang woke up early. Now was not the time to enjoy the blessings. There was still a long way to go. Time was limited. He had to seize the time to complete his plan to make a gun.
.
"You big sloth bear, what time has it been and you are still sleeping?" Lin Shuhang kicked the crazy general: "Get up quickly and go find some wood. Let's start processing these bamboos."
In this way, a new day began at Lin Shuhang's urging.
Since this earthen pot is a disposable earthen pot, Lin Shuhang does not plan to use it for a long time, so he does not need to handle it like pottery.
After a night of drying in the shade, the clay pot has completely solidified and only needs to be baked over fire again before it can be used.
Lin Shuhang lit a fire around the clay pot and baked it for about half an hour. The clay pot had completely dried out the water and became very dry and hard.
He tapped the wall of the clay pot with a stick. It was hard and made a crisp sound like porcelain. Lin Shuhang felt that it was almost done, so he asked the mad general to fill the pot with water.
Acid rain is extremely corrosive and cannot be used to treat bamboo, otherwise the bamboo will become rotten.
The water used was mountain spring water brought from nearby by the crazy general.
This kind of water is groundwater and has no harmful effects. It is drinkable. Lin Shuhang and Crazy General have been drinking this kind of water in the past few days.
After filling the earthen pot with spring water, Lin Shuhang increased the heat.
There is no shortage of wood in the forest. The fire burned fiercely for more than an hour, and the water in the clay pot boiled and bubbled out.
After the water boiled, Lin Shuhang ordered the crazy general to put the bamboo used to make gun barrels into the pot.
Boiling bamboo is different from cooking other things. Every fiber of the bamboo must fully absorb water. This process takes about five hours.
Afterwards, place the cooked bamboo in a cool and ventilated place and let it dry naturally for 2-3 days before the bamboo is considered ready.
Although the process of doing this is tedious, only heat-treated bamboo will become hard and difficult to crack.
Time is limited. If the method of boiling bamboo fails, the entire gun-making plan may be forced to abort. Of course, such an important thing must not be done.
Lin Shuhang is a cautious person. Faced with such an important matter, he will not bet all his treasures in one basket. In addition to boiling bamboo, Lin Shuhang also implemented another backup treatment plan - oil immersion.
Like boiled bamboo, soaking in oil is also the most commonly used method for treating bamboo among the people.
Oil is a liquid substance composed of hydrocarbons. Bamboo soaked in oil is not only hard in texture, but also can remain immortal for thousands of years.
However, in the primitive prehistoric world, oil was a resource that was difficult to obtain.
"I have to find a way to get some oil!" In the small courtyard, Lin Shuhang fell into deep thought.
There are five types of oils in nature, namely vegetable oil, animal oil, mineral oil, essential oil and silicone oil.
In addition to vegetable oils and animal oils, other oils require complex mining and refining technologies, especially mineral oils, which are buried deep in the formation and are very difficult to extract.
This is a barren prehistoric place that is separated from all civilizations. Lin Shuhang does not have the ability to mine or refine it in terms of technology or tools. The only oils that can be obtained are vegetable oils and animal oils.
Animal oil is also fatty oil. Fatty oil can be obtained in a wide range of ways. Whether flying in the sky, running on the ground, or swimming in the water, only organic life has fat on its body, such as pigs, cows, and sheep.
Chicken, snake, fish, seal, etc.
Compared with animal oil, there are many ways to extract vegetable oil, such as soybeans, peanuts, sesame seeds, olive fruits, sunflower seeds, palm fruits, coconuts, and castor. These plants can extract vegetable oil through special methods.
The area where Lin Shuhang and the Crazy General were located was called Giant Insect Ridge. Giant Insect Ridge was a very mysterious area. Unlike other areas, there were only all kinds of strange insects and no large animals for Lin Shuhang to refine oil.
Considering the current situation, Lin Shuhang finally decided to refine vegetable oil.
"Crazy General, go out with me later and we'll find some plants that can refine oil!"
Lin Shuhang was a man of action, so he did what he said. He immediately called General Mad to go to the nearby woods to investigate, and finally identified a plant that could be used to refine oil - palm trees.
Palm tree, also called oil palm, is a common woody plant in tropical areas.
The fruit of this plant is rich in oil, and both the pulp and palm kernel contain oil. The pulp contains 46% to 50% oil, and the palm kernel contains 45% to 50% oil. During the peak period, the annual fruit yield of each oil palm tree can be
Up to 100 kilograms, it is one of the plants with the highest oil yield on earth.
The oil production per unit area of oil palm fruit is more than 3 times higher than that of coconut, 7 to 8 times higher than that of peanuts, and 9 to 10 times higher than that of soybeans. Therefore, oil palm fruit is also known as the "World's Oil King".
The fruits of this plant not only have high yields, but are also widely used. In addition to being edible, palm oil and palm kernel oil are also important industrial raw materials and have a wide range of uses in industry.
For example, palm oil can be used to make soap, vitamin A, rust inhibitors, lubricants, internal combustion engine fuel, etc.
Making palm oil does not require advanced refining processes, and palm oil can be refined with some simple homespun methods.
First, the picked ripe nuts must be put into a large pot and boiled to loosen the fiber on the outer layer of the palm fruit. The boiled nuts are soaked in a large pool, then the fruits are crushed, and the impurities in the oil are filtered through a screen.
Scoop out the nuts and fiber.
After repeatedly filtering the oil, what remains in the pool is a mixture of oil and water.
The mass of oil is lighter than water, and it will float on water when mixed with water. If you find a way to skim off the floating oil on top, the refining of palm oil will be completed.
Fuhe Rainforest is known as a botanical expo. More than 96% of the plants on the earth grow here, so there are still a lot of palm trees.
In order to pick palm fruits for oil refining, Lin Shuhang used rattan to weave two large frames. The giant rattan basket was as big as a truck, and each basket could hold almost five tons of things.
After more than half an hour of picking, Lin Shuhang and Crazy General brought back two baskets of palm fruits from the forest.
Next is oil refining.
At this time, the bamboo in the pot had been cooked. Before refining the oil, Lin Shuhang and Crazy General took the bamboo out of the pot with sticks and put it in the yard to dry.
The remaining empty pot is used to cook palm fruits.
After fishing out the processed bamboo, Lin Shuhang poured all the picked palm fruits into the clay pot and started to add firewood and cook over high heat.
Taking advantage of this period, Lin Shuhang ordered the crazy general to dig a large pit in the ground for soaking palm fruits.
This pit is 10 meters x 10 meters x 5 meters and can hold hundreds of tons of things.
After the large earthen pond for soaking the palm fruits was dug, the palm fruits in the earthen pot were just cooked.
After taking out the cooked palm fruits and putting them into the soaking pool to cool down, Lin Shuhang asked the Crazy General to jump into the pit and crush the palm fruits with his feet.
After crushing the palm fruit, you will get a pool of oil-water mixture full of impurities such as fruit shell and fiber.
The next step is to separate the impurities in the oil and water.
In order to fish out the impurities in the oil pool, Lin Shuhang weaved a screen with bamboo slices. Using the screen, he quickly fished out all the impurities in the oil pool.
What's left in the pool is a mixture of oil and water, about sixty or seventy tons.
After finding two bamboo tubes, Lin Shuhang and Crazy General lay down by the oil pool and collected the palm oil inside.
The extracted palm oil was placed in the large square earthen pot by Lin Shuhang and Mad General.
As Lin Shuhang and Crazy General continued to extract, the oil in the clay pot gradually increased.
It has to be said that the oil yield rate of this palm fruit is very high. More than 3 tons of palm oil were refined from more than 10 tons of palm fruits. In addition to discarding some oil that could not be separated, Lin Shuhang re-extracted nearly 2 tons of palm oil from the oil pool.
I am quite satisfied with the palm oil.
"This much oil should be enough!" Looking at the refined palm oil, Lin Shuhang wiped his sweat and let out a long sigh of relief.
