Steampunk City [Infrastructure]

The steam engine is the greatest invention in human history, and it represents an era.

It can drive cars to run on the road, and it has created such an incredible existence as a steam train.

Who would have thought that just two tanks could pull a train like a dragon on a long voyage.

Just looking at the appearance, this is almost unimaginable, but after learning the principle, it seems to be the same thing.

Just like a TV can display images, and a speaker can produce sound. From a layman's point of view, the principle of its operation is completely unknown, but from an insider's point of view, it may be as simple as one plus one equals two.

riverside.

Luo Zhan "slightly" approached the river and began to connect the pipes. The soft boiled dinosaur skin was used between the two pipes, which was the skin of the Triceratops they hunted last time, so that the pipes could be flexible. bending.

Push in the direction of the river as soon as you connect a section.

Pushing one section at a time in this way can push the pipeline into the river from a distance.

Fortunately, they burned enough pottery pipes, otherwise Luo Zhan would have moved the water pump so far away from the river, and the length would not be enough.

The process was a little frightening, Luo Zhan felt that all the courage in his life had been used up now, and his heart was about to jump out.

He was plowing the land and studying the steam engine. For this moment, he had to complete the last step even though his body was trembling.

The pottery pipe is not too thick, because Luo Zhan thinks that his steam engine should not be particularly powerful, and it is too thick to pump water.

After the plumbing was done, Luo Zhan was already sweating profusely, because of the hot weather and the fright.

After wiping off a handful of sweat, the final pipe was connected to the piston box and the boiler, which was filled with water.

A bonfire was lit, and it burned.

Salmon looked confused and couldn't understand at all.

The heat transfer effect of the boiler made of pottery is indeed a bit poor. After burning for a while, the inside of the sealed boiler began to boil.

"clatter!"

Suddenly, a strange sound came from inside the piston box.

Salmon scratched his head, thinking he heard it wrong.

Luo Zhan's eyes lit up, and it started. It was the sound of steam pushing the piston, and he quickly increased the firepower.

"Da da!"

"Da da da……!"

The sound was intermittent, and finally joined together, becoming a continuous sound.

Driven by the steam, the piston moves repeatedly at an incredible frequency at a high speed, pulling the connecting rod and driving the wheel inside the box.

"Hoohoo!"

The sound of the wheels spinning.

The sound of "monkey monkey" can be heard from time to time in the pipe, like the sound from the throat of a person who is about to die.

It is the sound of airflow, and the runner is driving the airflow in the pipe.

This is the simplest working principle of a steam pump.

After waiting for a while, there was still no water.

Luo Ran thought about it, and poured some water in from the spout.

This water is still waste water when boiling salt, and there is really no excess water.

Salmon scratched his head as he looked at the two strange boxes that made strange noises. He was in a daze. Since this afternoon, he didn't know what he was doing.

The little patriarch used to be weird every day, but today is the weirdest.

When the sound was heard just now, he was startled, for fear of attracting the beasts in the river, but fortunately, as the sound continued, the sound became quieter.

Luo Zhan was also very nervous. Although this steam pump was built step by step according to the teaching in the video, he couldn't guarantee that it would be successful.

The salmon couldn't help it, and asked, "What are we waiting for?"

Luo Zhe pointed to the pottery pipe that came out of the water, "Wait for the water."

Salmon opened its mouth.

Stretching out his eyes to look into the pottery pipe, it's impossible, this pipe was made by him, how could water come out of it?

His whole eyes were leaning against the mouth of the pottery pipe, and he couldn't see anything in the pitch black inside, but he could feel a slight wind blowing on his eyes.

"Cuckoo."

Suddenly, there was a strange sound in the pipe.

"Cuckoo, cluck" continuously.

Before the salmon could react, "wow" something rushed out of the pipe.

Salmon retreated reflexively, but the white stuff that rushed out completely splashed on his face, and he sat down on the ground in fright.

Salmon touched the cold thing on his face with his hand. After a long time, he let out an exclamation from his small mouth, "It's water! It's water!"

White water!

The pottery pipe is not too big, and the power of the water flowing out is not too strong. It is about the thickness of a fist. The power provided by this steam engine is indeed very different from that of a steam engine that can pull a train.

But the white water is still the most dazzling thing now.

It worked!

Luo Zhan clenched his fists, his steam pump really pumped out the water.

The salmon kept hugging Luo Zhan's thigh, shaking his little head like a convulsion, "It's water, a lot of water!"

He knew how difficult it was to transport water in the tribe before.

I couldn't stop being so excited.

Until, Luo Zhan picked up the pottery pipe that came out of the water and sprinkled water on him from a high place, "How about taking a bath?"

The last part of the pottery pipe that comes out of the water is connected by several pottery pipes with animal skins, and the flexibility is not bad.

Salmon's expression was particularly rich. First, he opened his mouth wide in disbelief, as if he had heard the most incredible thing in the world.

Then the mouth slowly closed, the eyes narrowed into a slit happily, and let the water wash over his body, feeling the extreme coolness brought by the splash of water in this hot weather.

Under the sun, the water reflected light. A child raised his face and let the water splash down, laughing from the bottom of his heart.

This is something salmon has never experienced before.

If he wasted water like this before, he would have to be beaten to death by the adults in the clan. This is something unimaginable and unthinkable.

"so comfortable."

Luo Zhan flushed the salmon and told him to wash it thoroughly.

When the old patriarch was here before, Luo Zhan could still wipe his body with water a little, but the salmon couldn't do it, and he didn't even have enough water to drink, let alone take a bath.

So you can imagine how dirty the salmon is.

The white water washes down from above, and it can change color when it reaches the ground.

Salmon was a little shy, but his mouth was stiff, "We... all the children of our tribe are like this."

After the salmon was cleaned, it seemed to be a circle smaller, and Luo Yan almost didn't recognize it.

Salmon was even more surprised to see his little arm in a daze. Is this him?

He was originally small, but now he looks white and tender, like a small radish.

Luo Zhan also took a shower, the comfort of taking a cold shower in hot weather is indescribable.

After washing off all the dirt and dirt, I feel refreshed.

By the way, I also washed the robe on my body, and roasted it on the fire next to it, the robe will dry soon.

"The totem on the robe is gone." Salmon felt a little distressed, this is his favorite thing.

Luo Lixin said, this is not easy, he will draw it with charcoal later.

The boiler makes a "woo" sound from time to time. It is because there is too much steam in the boiler, which causes the internal pressure to be too high, and the exhaust valve is squeezed open.

This will ensure that the boiler does not explode.

Luo Zhan really doesn't need to think too much about these problems, because the video clearly explains these hidden dangers, and how to pay attention to and deal with these problems is clearly listed.

He is not engaged in research, he is the user of the results.

Luo Zan thought that the water coming out was the size of a fist, which was enough, and it could gradually fill his cultivated land with water.

However, the pipes connected to the cultivated land are not enough. It is definitely not enough to store water for the cultivated land today. If you have time, burn more pipes to connect to the cultivated land. After all, this place is a little closer to the river. It will be miserable.

The core problem of irrigation has been solved, and the others are minor problems. His millet can be planted immediately.

The joyful mood is unimaginable.

Luo Zhan played with the salmon until the evening, and even bathed the snake mother, and then went back laughing all the way.

The only bad thing is that they have no food, and they are doomed to starve tonight, but they went back after filling their stomachs with water, so let's use water to satisfy their hunger.

When we returned to the platform in front of the cave, it was already getting late, and we didn’t see anyone in charge, so we probably still haven’t come back.

Luo Zhi pulled the salmon and said, "Rest early today, and tomorrow we will bring some water out to see if we can get food like last time."

Now they can't hunt at all, and the people outside are so short of water, so Luo Zhan started to get the idea of ​​these water.

Salmon scratched his wet hair, "But... I think we will be robbed."

Luo Zhan: "..."

In fact, what Salmon said is right, they are so weak, they don’t know whether others will exchange food for them, but they are basically robbed by a percentage, and the cruelty outside has never been seen before. , Speaking of which, it is luck that they come back alive every time.

But they have to go out and find food, or they will starve to death.

Now the outside situation, the weather is getting hotter and hotter, and the water shortage is getting worse, so I have to take the water out to try.

Luo Yan frowned, "Let me think about it."

In the evening, Luo Ji tossed and turned to think of a solution, but he still didn't come back all night.

Luo Zhan's eyes could not help but brighten up when he thought of Zhao Zi, he was the most powerful beast warrior he had ever seen, maybe... he could make a fool of himself.

……

The next day, Luo Zhan and the salmon went out with their bellies growling, and the mother snake hung several buckets full of water.

The difference between going out this time and the previous ones is that there is an extra eye pattern between the foreheads of Luo Zhan and Salmon, which is exactly the same as the eye pattern on the forehead of the bearer.

"Can this work?" asked the salmon.

Luo Zhan is not sure, but he has to try, this is the only way for them to survive now.

They have water, but they are weak and cannot keep it, so they have to pretend to be members of the Xietong tribe.

"I hope the reputation of the Xietong tribe is strong enough."

A tribe with such powerful people should be very powerful, right?

However, we must not let Liao Xi know that they are pretending to be members of the Xietong tribe. Luo Zhan shivered when he thought of Lie Xi.

A giant python and two trembling people headed towards the grassland, where a strange water shed was set up.

At this moment, Luo Zhan didn't expect what kind of exaggerated storm his buckets of water created.
