Prehistoric Survival Records

After expressing their pure love to each other, the two brothers ate the remaining berries in the basket, and now there is only a yellow and green mass left in the small basket.

Rigg began teaching Charlie again.

"It's taken out of bamboo, called Zhuru, does Charlie still remember bamboo, it's the kind of blue straight, hollow bamboo."

He put the yellow-green thing in front of Charlie again so that he could observe it carefully.

"This is Zhuru...it is taken from bamboo stalks. Zhuru is a very useful medicinal material. It can clear away heat and reduce phlegm, relieve cough and moisten the lungs, and heal internal injuries. It also has an immediate effect , just stopped vomiting."

"So if Shi Lan keeps vomiting, give him this pounded water, and it will stop immediately."

Seeing that Charlie listened seriously, Rieg continued: "Oh, actually, I don't know a lot about medicine. These are just the common sense of my time. If Shi Lan really got some intractable disease, I might be helpless." Well, fortunately, it happened to work."

"If there wasn't this bamboo forest, it would be hard to find other herbs that can produce the same effect in the freezing and snowy world right now."

"The bamboo forest was discovered in a timely manner!" Finally, Rieger concluded.

"Shhhhhhhhhhhhhhhhhhhhhhhhhhhh." Charlie also agreed with this conclusion, of course, the main emotion in his agreement was to express his love for the small backpack.

The two brothers kissed and chatted sweetly, just like any pair of friendly cubs in the tribe, sharing snacks, talking small words, and wandering around the tribe. Although there is a ten-mile glacier outside, their hearts are Leisurely and at ease.

The time will soon come when the charcoal from the first kiln is about to be released.

There are many tricks in burning qualified charcoal in a kiln.

If the charcoal kiln is like the previous life, even if it is an earthen kiln, the temperature can be adjusted several times during the kiln firing process. The temperature is kept at 100 degrees and 170 degrees for two and a half hours each, so that the moisture and gas in the wood can evaporate as much as possible, and the wood can be dehydrated and dried quickly.

When all the moisture in the wood evaporates, the wood will become completely dry, and then the temperature in the kiln will be raised to about 300 degrees quickly. At this time, various organic and inorganic substances in the wood will be decomposed under the action of high temperature, forming Carbon dioxide and a small amount of acetic acid, etc., when the temperature of the kiln rises above 300 degrees, flammable liquids and gases such as wood tar, methane, and ethylene will escape.

Due to thermal decomposition, a large amount of combustible liquid and gas are produced, and these combustibles will intensify the combustion in the kiln, raising the temperature in the kiln to 400 degrees, and the wood will be distilled into charcoal at high temperature.

If conditions permit, artificial means can also be used to increase the temperature in the kiln to above 800 degrees, so that the volatile substances in the charcoal can be further decomposed, and industrial activated carbon and graphite with higher carbon content can be produced. product.

But in the case of this rudimentary mud kiln, the last step was something Rieger hadn't been thinking about at all.

After all, the technology tree has not reached that point yet. Besides, for the orcs here, they lack everything, except fuel. Burning some charcoal to play is purely Lige's own experiment. On the one hand, it is much better than simple wood, and the temperature of the furnace can be raised. Once the fuel problem is solved, the following technology points can be developed.

I don’t know that in the old technological revolution a few interstellar years ago, the descendants of the Anglo-Saxons solved the fuel problem before they built the steam engine, and only then did they have the technological leap forward development.

Throughout the history of mankind, there are countless things like this kind of flashes of inspiration that have caused drastic changes. Although the knowledge accumulation of the orcs here has not reached that point, but he Rieger has returned to prehistoric times from the era after the technological explosion billions of years later. It's a man standing on top of a giant's head. Little charcoal or something, I'm not worried at all!

Even though he thought so, the trembling fingers still betrayed Rieger's true inner thoughts—he was still a little worried.

Charlie was a very perceptive chick, and he put his little head in Rigg's hand and rubbed it.

No wonder people all over the world like to keep cute pets. At this time, cute little animals have a 100% soothing effect on the heart. I can feel Lige's elastic and dull hair sliding back and forth in the palm of my hand. , suddenly calmed down.

Even if this kiln fails, then there is another kiln. On this piece of land, he doesn't have many things, but there are many raw materials, local tyrants!No matter how many times you try it, you are not afraid!

A few people stood devoutly in front of the half-person-high soil bag, the wind was blowing, and the ice was freezing. At first, no one moved, but Lige waved his paw towards the sky, what are you waiting for, start the kiln.

The two big orcs rushed forward impatiently.

Opening a kiln sounds good, but in fact it is just to remove the simple mud seal. Although it is so simple that it is not worth mentioning, the two elder brothers still do it very carefully. They probably think that Lige is left with dust. The non-slick mud seal was still useful, so they paid special attention when picking it up. It was Lige who let them loosen their hands and feet to pick it up boldly, so they used all fours to remove the mud shell neatly.

As soon as it was removed, a pile of black and gray things piled up in the center of the kiln was exposed to the sun.

Well, from the appearance, it is indeed charcoal, Rieg held his chin to confirm it with his eyes.

As for the quality, Lige picked up a piece of charcoal and snapped it in the middle with two small hands. The cut was clear and black, and even the core part in the middle was completely carbonized. Lige nodded in satisfaction.

He threw the two pieces in the pile of charcoal at will, picked up another whole one, and flicked it lightly with his nails. The sound was transparent and round, and relatively loud, completely different from the dull sound made by hitting wood.

Then Rieg smoked a few more sticks of charcoal and tested them in the same way. Finally, he stood up, faced two anxious faces, showed a big smile, and announced——

"very successful."

"It's good charcoal."

"We can pick them all up!"

Suddenly, two very excited cheers sounded in the open space. The way for the excited orcs to express their joy is to use their bodies, cheer and run.

Billy yelled and excitedly ran Charlie on his shoulders in a wide circle around the clearing, and when he got excited, he threw Charlie into the air and caught him again.

Charlie seemed to enjoy the thrill of the action, whistling and screaming.

Well, Charlie doesn't look big, but Rieger knows Charlie's weight. Even Quinn's father can hardly throw Charlie up and catch him properly. The only one in the family who can play catch with Charlie Only Papa Laika is left, but the Papa Laika of the feline orc has strong explosive power in an instant, but his endurance is average. Usually, he can only throw and catch a few times, which means that his waist is not good enough.

Rigg looked in awe at Billy, who was throwing Charlie around casually. It turned out to be an orc from a brown bear known for its brute force.

It was rare that Charlie could let go of playing, and Rigg let them go.

Raising cubs in prehistoric times is not like the modern set of excessive protection. If it was in the era of Lige, if parents dared to play such a dangerous game with their children, they would be drowned by spittle. If they were accidentally photographed After the photos are posted on the interstellar network, within half an hour the Children's Protection Association will bring volunteers to the door to crusade, and the parents must be forced to write a letter of guarantee and press their fingerprints to promise that in the future, they will definitely joke in moderation and not joke about children's lives. By the way, obediently pay Pay the fine and you're done.

Fortunately, it is prehistoric now, and the orcs and the cubs are not strong enough. Rigg dared to say that if Charlie was accidentally caught and fell to the ground, the floor was probably what he needed to worry about—yes, Charlie is that scary Cub.
