Yang Muyun has always been curious about why the temperature in underground caves is higher than outside.
The hot and cold air at the entrance and exit of the underground city met and was always shrouded in white mist. Seeing the heat dissipate in vain, Yang Muyun suddenly felt like he wasted everything.
If you can find a heat source, you can do a lot of things by yourself. Among other things, the problem of greenhouses will be solved, and growing grain and vegetables in the river valley will not be a problem.
As he followed the kobolds, Yang Muyun felt that the air was getting hotter and drier, and there was a faint smell of sulfur hanging over the tip of his nose.
Is it underground magma?
"Master, we are ahead. We searched several underground caves but could not find the heat source, so we suspected whether it was underground. After several days of exploration, we finally determined the location. After some digging, we found it.
"
The kobolds held torches, illuminating the front brightly.
Yang Muyun suddenly saw a huge pond, but the water surface of the pond was rolling, steaming, and bubbling.
"spa?"
Although it's not magma, it's almost there.
Blackhead replied: "Master, this should be the river that disappeared in the river valley. Due to the drop in water level, it changed from an above-ground river to an underground river. It met the blood of the earth and turned into a boiling river."
The "blood of the earth" mentioned by Black Head probably refers to magma.
Yang Muyun nodded, and then tried to put his palms on the water. After getting used to it for a while, he tried to insert his fingers into the water.
Seeing this scene, Blackhead immediately warned, "Master, be careful."
hiss!
Yang Muyun grinned and retracted his arm, waving his fingers back and forth in an attempt to shake away the pain on his fingers.
hot!
Too hot!
Although there was no blistering or peeling, it was still uncomfortable. My fingers were red and swollen.
If the hot spring is not good, it can burn people to death.
But Yang Muyun immediately thought of the use of hot spring water - there is no need to boil water to cook slime, and the scale of the flesh and blood factory can be expanded.
Immediately, Yang Muyun thought about how to pump the hot spring water from the underground city to the ground.
pump?
No, this is expensive and expensive, and it also requires electricity and oil.
siphon.
Yang Muyun immediately thought of this.
Soon, Dashi and Laxida both came to the hot spring.
Looking at the bubbling pool, Dashi couldn't help but lick his lips.
"Chief, can we cook the meat here?"
Yang Muyun:??
This idea is really strange.
But if you think about it carefully, it's really possible.
"Ms. Laxida, I want to open a pipe to connect this pool and the ground. The pipe should be roughly like this, and the middle needs to be like this. In this way... do you think there is any problem?"
Laxida nodded, "I can manipulate the rocks to form the kind of pipeline you mentioned, and ensure that it is watertight, but whether I can send the water out is beyond my ability."
Yang Muyun said: "Ms. Laxida, don't worry, as long as the pipeline is installed, I will do the rest."
Laxida nodded, walked around the hot spring pool, reinforced the edge of the pool, and then stood a dozen steps away from the hot spring pool.
I saw its paws patting on the ground, as if there was an elevator under my feet. Laxida's body slowly sank, sinking to a certain depth, and Laxida stepped forward.
There was no need for a level or a locator. Laxida just walked leisurely. The rocks in front of him opened up like water. After Laxida passed by, they all solidified, leaving a passage made purely of rocks.
.
Yang Muyun secretly admired in his heart: It's really a human-shaped TBM. Oh no, a bear-shaped TBM.
The kobolds also lamented, "Master, if we were to dig this passage, it would be time-consuming and labor-intensive. We also have to be careful about the direction. Once we dig wrong, all our efforts will be lost."
"If a landslide occurs during excavation, a lot of manpower will be lost."
"Yes, the Earth Bear is so powerful. One trip for her is worth more than half a year of digging."
Seeing the water in the hot spring pool flowing in along the pipe, Yang Muyun waved his hand and said, "Let's go to the ground."
As soon as a group of people returned to the river valley, they saw Laxida walking out of the mountain wall. Behind her was a dark and deep passage.
Looking behind her, Laxida looked like she had expected this.
"The water flows downward, young savage, you have made an unwise decision this time."
Yang Muyun smiled, measured the diameter of the hole with a wooden stick, then rushed into the dungeon without stopping and tinkered with the slime factory. Soon, Yang Muyun returned to the hole with a large tool.
Putting the tool on the hole and checking the air tightness, Yang Muyun pressed and pressed against a wooden stick, and pressed again and again.
This is a device similar to killing a well. It has a piston and a valve. Both are one-way valves that allow air to go up instead of down.
When the piston moves up, the valve opens, and the air in the lower tube can be pumped into the upper cavity. When the piston moves down, the valve closes, and the air comes out from the side of the piston. This cycle creates a vacuum in the lower tube, and the water
Under the action of atmospheric pressure, it was drawn up.
Once the water is pumped up, a siphon effect can be formed, and water can be continuously pumped out even without the help of external force.
Laxida looked at the tool in Yang Muyun's hand curiously, then lay down in boredom, quietly waiting for Yang Muyun to make a fool of himself.
Yang Muyun kept pressing for a long time, and several pistons were broken. In the end, there was still no water. Even the goblin who blindly worshiped Yang Muyun gradually had his confidence shaken.
The kobolds were also experts at digging holes. They silently calculated the distance from the underground heat source to the ground, and then shook their heads.
It's too far, and it's impossible to even think about letting water flow from underground to the surface.
Yang Muyun didn't believe in evil and was still pressing down.
Dashi couldn't stand it any longer and said, "Chief, it's getting late, why don't we eat first?"
Yang Muyun wiped his sweat and said, "Dashi, do you believe me?"
Dashi nodded immediately, "Chief, I definitely believe you."
Yang Muyun pointed to the open space in front of him, "Okay, let's cook the meat in that place later. Go ahead and prepare the ingredients for a bonfire dinner today."
The elephant-headed man looked at Yang Muyun's sweaty appearance and said, "Master, let us take your place."
Yang Muyun waved his hand, "If you want to help, dig a pool here."
The elephant-headed people lay down on the ground and dug without saying a word, and the tauren and kobolds also joined in.
Rashida secretly smiled, this young barbarian was so proud that he would not blame him for such trivial matters as digging holes.
But the next moment, the smile on Laxida's lips froze.
Because through the connection with the earth, Laxida sensed some incredible changes.
After a while, the people around Yang Muyun became commotion.
"The sound of water."
"Yes, I heard the sound of water too."
Immediately, everyone looked at Yang Muyun with a hint of admiration.
The owner actually did it and actually led the water from the ground to the surface.
Yang Muyun has also been paying attention to the movement in the pipe. When he heard the sound of rushing water, Yang Muyun immediately removed the piston tool from the hole.
"Spread out, hurry up, spread out."
The sound of water is louder and closer.
Pfft, pfft... clatter...
A wave of heat erupted from the cave and shot a hundred steps away.
After a while, the heat wave slowly subsided, and it became sluggish little by little, shrinking from hundreds of steps to dozens of steps, then to more than ten steps, and finally fell into the big pit dug by the elephant-headed man with a favorable wind, as if his shoes were still wet.
After a while, the big pit was filled with water.
When hot water meets cold air, wisps of white air suddenly rise from the water, and a heat wave spreads. The surrounding snow shrinks, melts, and disappears into the soil at a speed visible to the naked eye.
At the same time, a large wave of power of faith floated up from many of his relatives, converging on Yang Muyun like a tired bird throwing itself into the forest.
