Prehistoric Survival Records

Bring the subject back from the pig.

After finishing the experimental field and the five little pigs, there was another problem with the collective bathroom on the construction site.

Rieger didn't want to deal with the group bathroom at first. The orcs were usually itchy. They either rubbed on the rough bark or jumped into the river to swim. After rolling a few times before getting up, their bodies were basically clean.

Wanting to have a bathroom to shower or take a bath is a habit of Rieger as a later generation. It’s fine if he didn’t have the conditions before. Now that so many houses have been built, this bathroom is not bad. I didn’t expect to wait for him to express his ideas. When I told the orcs on the construction site, everyone was very interested in taking a bath in the bathhouse, especially the boys who had taken a hot bath with Lige, and they all said that they were very comfortable and very excited Son, we want too.

So it was expected that the small and medium-sized bathhouses would be built bigger and bigger, and then a large bathhouse that could accommodate thirty or forty orcs to take a bath together was directly built.

Considering that taking a hot bath mainly happened in winter, Rieg installed the fireplace in the activity room as it was in the bathroom, and installed some half-person-high wooden boards on the wall to form a room. It looks like a small room, although the scene of walking birds with each other is still unavoidable, try to cover it as much as possible.

Each small room is fifteen centimeters higher than the average height of the orcs, and a shower is installed. The shower is a method Billy came up with. He found a piece of wood and hollowed out the middle, covered it with a board with a small hole, and then followed it. The hollow bamboo in the middle was connected together, and when water was poured into the bamboo pipe, the water sprayed out from the shower. Rigg asked Billy to stand under the shower to try the feeling. When the ground sprayed on Billy's body from multiple angles and directions, he was obviously stunned by this unusual itching feeling. Soon the big man got used to the feeling of hot water showering his head, and then he was out of control. In order to reward Billy for his hard work these days and let him enjoy the comfort of being able to shower more, Rigg kept pouring hot water into the raised wooden bucket, allowing Billy to take a hot bath happily.

As for the necessity of the shower room?

Just looking at the eagerness of the other orcs who were almost drooling with envy, Rieg rubbed his sore arm, feeling that he had already got the answer to this question.

However, although the pipe system is solved by connecting the hollow bamboo, how to continuously supply thirty orcs to shower at the same time is a big problem. The water supply is easy to solve. You can install a large water tank on the roof or build a large For the pool, when it is necessary to use it, it is necessary to concentrate on boiling the water once. This needs to be carefully calculated, and it is too troublesome to transport the water manually, so the details need to be carefully considered.

Rigg grabbed a piece of parchment, wrote a lot of formulas on it with charcoal sticks, and drew some diagrams. Then he called Billy over, and the two of them chattered and chatted for days, and finally put together the first pulley block in prehistoric times. It was fiddled with.

Then Rieg mysteriously called all the orcs together, saying that he would perform a show for them, and he would move a huge rock to the roof.

The rock that Rieger pointed to was not particularly large, but very heavy. It was originally half exposed outside the soil layer, but was dug out by the orcs and prepared to be thrown outside the construction site.

After taking a look at Lige's small body, and then at the big rock, he was the first to laugh out loud.

"Hahahaha, Second Treasure, although you are the smartest here, you are weak, so you should stop playing. If you hit your toe, it will be very painful."

The other orcs also turned their backs and laughed secretly. They also had the same thought as Tscha Tsa, but they didn't say it out loud, for fear that Rigg would twist his waist and hurt Rieg's self-esteem.

Hey, I'm so angry, really, to underestimate him so much.

Rigg tied the knot to the rock, and installed a pulley block composed of two fixed pulleys and two movable pulleys on the side of the wall near the boiling water room, in order to surprise everyone (the bully orcs can't understand it with physics knowledge) Oops).

Unexpectedly, before Lige could show his skills, the dog clan cub Xueqiu who swooped over and grabbed one end of the rope stole the limelight. Leaning closer to Lige, the rock tied with the knot slowly lifted off the ground and rose into the air.

The orcs who originally smiled kindly to show that we believe in you, don't try to show us the expressions, collectively changed to Σ(⊙▽⊙'a.

Rubbing Snowball's head, and taking the end of the rope from his mouth, Rieger felt that although he did not raise the stone by himself, the effect was even more astonishing unintentionally when Snowball made it (Snowball also Not as big as a rock).

After the shock, the orcs all expressed their disbelief, and even a few people doubted the authenticity of the stone, and Tscha was one of them. He strode forward, picked up the stone, and held the stone in his arms. The weight told him that the stone was genuine.

Fuck, is this the beast god's preference again?

"Trash, is the stone real or fake?" Well, there are still a few who don't believe it.

"You'll know if it's true or not by weighing the weight yourself." Chacha replied angrily.

The few orcs didn't mind, they took turns running over to confirm the weight of the stone, muttering, strange, no, very heavy.

Knowing that it was his turn to appear at this time, Rieg coughed softly, stood up, and solemnly introduced the principle and use of the pulley block to everyone.

What fulcrum, power, resistance, power arm, resistance arm.

What F=mg/5.

The talk was eloquent and eloquent, and I finally found a little bit of the feeling of giving lectures in my previous life.

The orcs saw how excited he was speaking, although they didn't understand at all, but when Rigg talked about these things, his face was full of radiance, exuding happiness from the inside out, and no one wanted to interrupt him, only Hua Just a little time, time, there is plenty.

When Lige came back to his senses after talking, he realized that the orcs were all looking at him dotingly, and they blushed involuntarily.

Being, being doted on by an adult of a clan, I, I am not very happy——

"Anyway, using this pulley block to pump water to the roof can save four-fifths of the effort. In short, it saves a lot of effort."

—Rig concludes.

Everyone understands the special labor saving. In order to let the orcs experience the feeling of labor saving, Lige asked everyone to come up and try it. First, hug the rock to feel the weight, and then pull the rope of the pulley block to experience the strength of the two methods. difference.

"So light, so light."

"It really saves effort."

"It's interesting."

But there are also silly voices, such as Zhacha said: "But I have great strength, and it is very easy to move water and stones."

Rieger patiently explained to him: "It's easy to carry a bucket of water, but you will be very tired if you move ten or a hundred buckets of water. In other words, you don't feel tired when you carry water up and down. What, if it is a member of the clan with a disability, is it inconvenient?"

Rieger explained to everyone: "We orcs have great strength, but no matter how strong we are, sometimes we can't move things. This is different. We can customize different pulleys according to the weight of the object. Theoretically In fact, as long as the pulley block can be used flexibly, all kinds of heavy objects in daily life can be solved, isn’t it great.”

"With this pulley block, the elderly in the clan, orcs with handicapped lower limbs, or orcs with one hand and one foot, can easily and conveniently operate this to fill the pool."

Seeing how the orcs listened carefully, Mr. Lige finally added——

"Anyway, I can't tell the benefits of the pulley. Today I just took it out and tried it. This is the most basic and crude version. I will study how to fix it and how to wind the rope in the future."

There is also a bucket, it is best to be able to automatically dump it into the edge of the pool after it is lifted up to the roof.

Scratching through his life's thick black hair, Rigg felt like he had a technical problem.

The principle of automatic dumping of the bucket is the change of the center of gravity. When the bucket is empty, the center of gravity is under the shaft, and the bucket keeps standing at attention. When it is filled with water, the center of gravity of the bucket changes to the shaft, and the bucket is dumped.

Using the principle of converting kinetic energy into gravitational potential energy, Gu Huaxia invented the waterwheel, and Gu Wonu invented the Xingzhu. This can be studied in depth when the farmland expands in the future, but there is no good way for the hot water bucket to pour itself Into the pool.

The method is not impossible, but now that there is a lack of precise devices, it is a bit dangerous. After all, what goes up to the pool is boiling water. If you make a mistake and fall down, the orc holding the rope below is made of meat. There is no copper skin and iron bones. Oh no.

Rieger thought of a lot of ways, but for the time being, he could only make the bucket rise and fit into the notch on the wall of the pool, make a groove at the bottom of the bucket near the edge, poke it with a pole, and pour the water in, although It's not automatic enough, but it's much more convenient than the orcs climbing up and down with buckets, and the speed is still very fast if you are proficient in doing it.

It is really not easy to practice showering in prehistoric times. Rig rubbed his stiff back with emotion.

The most troublesome group shower problem has been solved, and the rest are trivial matters. Finally, a large round pool is built in the center of the bathhouse for bathing. The first prehistoric group bathroom is basically completed, but if it is really To use it, you have to let the cement dry for a few days.

Fortunately, in the hot summer, everyone including Rieger said that they didn't want to take a hot bath so much, so let the bathhouse dry well.

......

The temperature difference between day and night on the grassland is large. When the temperature is the highest at noon, the surface temperature is almost 10 to [-] degrees. After the sun goes down at night, the temperature drops rapidly and drops to only about [-] degrees.

The dogs are local orcs, and they are used to it, but Lige and his tribe mainly lived in the tropical rainforest climate before, so they are not used to the temperature difference between day and night.

Recently, their work schedule has been changed to work in the morning and evening, and take a nap at noon and evening. This is still under the encouragement of Rigg, otherwise, with this group of lazy guys who have enough to eat, they will probably go to bed early. At night, it's like aestivation.

Every day before going to bed, Rieg would reflect on how much work he had ordered people to do today, but when the sun rose the next day, he immediately threw away the little guilt before going to bed, rightly, You can have guilt, but you still have to dry your teeth.

Rigg put his hand into the woolen skirt and scratched his buttocks, paused, and suddenly jumped three feet high.

Damn it, his lord Lige's little pp, which had been wrapped in a woolen skirt all this time, turned out to be long!prickly heat!son!up!

Prickly heat is a skin disease caused by blocked sweat glands in a hot and humid environment. It's not a big problem, it's just itching.

Rigg scratched, and scratched, and found, sadly, that it seemed to be getting more and more itchy.

Rigg's movement caught Charlie's attention, his round ice blue eyes were fixed on his brother's movements without blinking, the eyeballs moved with his scratching little paws, eager to peck.

It's a pity that Rigg saw his thoughts, and Charlie was strictly stopped before he even opened his mouth.

But Charlie is a very persistent bird, and he couldn't peck at Rigg's little paw, so he took off Rigg's panties, played tug-of-war with Rigg with the hem of the woolen skirt in his mouth, and laughed in his throat.

The play of the two brothers quickly attracted the attention of the fathers. With the light of the fire, Quinn pressed Rigg's dishonest paw, revealing a large patch of bright red prickly heat under the loose wool skirt .

This time, Rigg's protest was ineffective. He was fixed on the animal skin gently and irresistibly by the two fathers. Quinn took off Rigg's woolen skirt and carefully observed the distribution of prickly heat. The fathers watched over and over seriously.

Unable to resist, Rieg simply pretended to be dead, and pressed his face firmly into the fluff of Charlie's chest, but his ears turned red slightly.

Rieger silently said in his heart that I am only one year old, I am only one year old, I am still a baby, I am still a baby, in order to dilute the shyness in my heart.

Fortunately, Quinn's father's medical examination lasted only a short time.

"Wow, Erbao has prickly heat!" This is Laika's father, and he doesn't know what's so special about it.

"It's prickly heat, it's not serious. The big red patch should have been caught. Don't be afraid, it's fine." This is Quinn's father, always steady and gentle.

"Prickly heat is very common in summer. Every summer, people in the tribe will get prickly heat from being stuffed by animal skins. This year, they wear wool skirts, which are more breathable. The situation has improved a lot. This is all thanks to you, Erbao." Quinn's father, who concluded, began to comfort Rieger.

I knew it was prickly heat, but I didn't know it would be so itchy—this is a child who lived in a building with comfortable body temperature everywhere in his previous life, and he never had prickly heat at all.

"Let's leave it open for a few days and let it blow dry, it will get better soon." Laika's father made a final decision and deprived Lige of the right to pants.

"But—" Rigg still wanted to struggle.

"Sick children must be obedient, otherwise you will be naked during the day." Quinn's father resorted to the ultimate weapon, and ruthlessly suppressed Rieger.

Between fruit sleep and daytime fruit run, Rieger humiliatedly chose fruit sleep.

Really, does the brat have no right to pants?

Children can also be shy, okay, you group of infinite adults, at least give me a cover with animal skins.

Quinn said, no, it needs to be open, and you can hold Charlie to sleep. He is warm and cannot be frozen.

Rieger knew that Charlie had a high temperature, but it wasn't a matter of freezing or not, it was a matter of me not being naked.

Despite all kinds of complaints in his heart, Rieg quickly realized the beauty of sleeping naked.

The night breeze blew over the red, swollen and hot ass with a trace of coolness, and soon stopped the itching that made people scratch their ears and cheeks.

The itching stopped, and Rigg's drowsiness slowly came up, buried in Charlie's fragrant chest hair (wrong), Rieg let himself be invaded by sleepiness.

There is only one thought in the last trace of Qingming—the woolen skirt is still too hot in summer, and it is necessary to find a way to solve the problem of dressing as soon as possible.
