Song Xiaoshuang was the first to rush to the underground cave hall among several people, although he had already predicted in his heart that the energy crystal must be used for some mechanical device, and the numerous metal pipes inlaid in the middle of the wall indicated that the secret room of the sacrificial temple was also related to mechanical devices, but when he walked into the stone cave hall, he was still shocked by everything he saw.

In the cave with an area of hundreds of square meters, there are various sizes of but all black metal pipes and valves on the stone floor and walls, the pipes and valves are intricately connected together, at first glance, Song Xiaoshuang reminds Song Xiaoshuang of the engine room of an old-fashioned submarine, a device connected to several pipes with a diameter of more than the thickness of a thigh like a boiler is particularly conspicuous, and what makes people feel confused is that next to the valves that look like a lot, there is no mechanical indicator such as a pressure gauge to refer to the pressure of these pipes.

There are two artificially dug passages from the hard rock in the stone wall in the back, and the voices of the two siblings Maijid and Saeed come from one of the passages, and the sound is very clear!

The top of the cave is clamped with a piper clamp with dozens of arms from the pipe that stretches out from one side of the stone wall, and the opening at the end of the pipe is like a jet fighter vector vent, and the sunlight that has been refracted countless times shoots out from the pipe, more than a dozen pillars of light that should have been refracted in one by one, after leaving the pipe on the top of the cave for half a meter, these pillars of light have become diffused for some reason, just like the light of the torch that gathers the light is no longer concentrated, and more than a dozen spots of light that have changed into countless diffuse forms have converged together to illuminate the cave hall with an area of several hundred square meters.

The remaining dozens of pillars of light all shone on the surface of a black lacquered arc-shaped metal device that was only more than two meters high, like a coal-fired boiler device, two meters high, swelling like a turnip, and more than two meters in diameter.

These pillars of light do not become diffused, and can be clearly seen projected on the metal surface to form light spots, giving people the first feeling that it is very similar to the sunlight shining on a newly unearthed mushroom (of course, many mushrooms do not need sunlight), and the arc-shaped metal device with a diameter of more than two meters looks like a mushroom top!

Song Xiaoshuang didn't care about the facilities that projected pillars of light, and through the exploration of his spiritual power, he had already understood that there were some small devices near the opening of the pipe that changed the projection form of light.

Song Xiaoshuang avoided the complex pipes on the ground and approached the device like a coal-fired boiler, because his spiritual power could not detect the inside of the metal mushroom top, but he could barely sense the same energy fluctuations as the two energy crystals in the pocket of his robe. There was not much spiritual power left to vaguely sense the energy fluctuations of the energy crystal!

When he found that there was a one-foot-sized metal door on the side of the metal mushroom top that was very hidden and could be opened, Song Xiaoshuang did not try to open the metal door with the embedded handle.

At this time, Isabel, Eliham and Farhad, who were following behind, had already walked into the cave hall, Isabel had already shouted that everything here was a great discovery, and turned his head to go back to the ground but hit the forbidden that had been closed, Song Xiaoshuang was a little speechless, so he had to speak to turn Isabel's attention to the strange device beside him.

Fahad, who walked in the last veil to cover his face, was a little surprised that Song Xiaoshuang's guess was really accurate, just like the device of a coal-fired boiler did play the role of an artificial fountain!

By regularly adding a few centimeters of cylindrical energy crystals to it, forming an energy force field that scientists say, pumping groundwater deep underground through the gaps between pipes and the ground, trickling water gushes out of the surface sand and moistens the entire oasis.

It's a great secret that only tribal leaders and wizards know about the Oasis! Farhad also became the leader of the tribe a few years ago, and after the wizard allowed him to enter here, Farhad suddenly realized that there was such a secret hidden in the underground of the oasis, when Maijid was just over two years old, and Saeed was still Emima's belly.

The upright Farhad is an old leader and wizard who went to France to watch the tribal warriors grow up, and there is naturally no problem in guarding the secrets of the tribe, and each oasis tribal leader not only has to protect the secrets of the underground caves, but also regularly takes out the black energy crystals from the storage room to supplement the consumption of energy crystals in the artificial fountain device, which is basically only once in a few years.

But because the energy crystal works to gather a lot of solar rays to work, the sunshine in the desert is not static, sandstorms, long-term foggy weather will affect the consumption of energy crystals, Farhad has to check the consumption level of energy crystals from time to time, otherwise this device will strike one day, and the artesian wells on the ground will no longer gush out sweet groundwater, which will be a disastrous consequence for the entire desert oasis!

Because even the wizard and the old leader are not sure whether this device that brings happiness to the oasis can be completely stopped, and can be restarted, after all, this is a secret inherited and guarded by generations of wizards and tribal leaders, and the people who designed and built these facilities have long since passed away, and no one can figure out the strict operating rules at the beginning.

Because every tribal leader has to enter the underground secret room of the sacrificial temple regularly and irregularly, and the artesian well that maintains the development of the oasis is next to the tamarisk tree dozens of meters away from the sacrificial temple, the villagers of the oasis tribe regard the mysterious behavior of the leader entering the underground secret room as doing some kind of prayer ritual that only the leader will do.

Farhad was still immersed in the memory, McJid's voice sounded in his ears, and when he came back to his senses, he saw that McJid and Saeed were each holding a few chili peppers from the secret room test field, Isabel held a dark red chili pepper in her hand, and shouted in Chinese: "Song Xiaoshuang, I will first go to see the experimental field where McJid planted peppers, there are also energy crystals, McJid said that the energy crystals are soaked in the tank, and there is refracted sunlight in the tank, which gives me a lot of inspiration, and I will leave it to you here, Let me know if you find anything. ”

"Farhad, how exactly does the device work here? Without a single mechanical instrument, no electrical equipment, it seemed very quiet, it is hard to imagine how the designers of more than a hundred years ago would have thought of providing energy with energy crystals, including the structure of the sacrificial temple above, the Oasis tribe simply did not have the ability to build this series of facilities! ”

Eliham, who covered her face with a veil, watched Isabel follow McJid and Saeed to the artificially dug stone passage, knowing that it was the so-called secret room, Eliham's eyes swept over Song Xiaoshuang, who was standing in front of a device and did not move, only to notice that Farhad who came in last had not spoken, but Farhad should be more aware of the situation here, and Eliham asked Farhad in awkward Chinese.

Letting Song Xiaoshuang and Isabel into the underground secret room is part of Farhad's plan, what is the matter if you don't speak, Elliham secretly scolded in her heart.

Before Fahad could speak, Song Xiaoshuang suddenly turned around and shouted in a low voice: "Eliham, be careful not to sit on the pipe!" ”

Song Xiaoshuang's voice, bluffing to sit on a row of pipes laid more than a foot above the ground, Ellieham's expression changed, the ass had not yet stood up straight next to a few pipes, looking back at the pipes, there was nothing on the pipes, the fingers just felt cold, Elliham felt that Song Xiaoshuang was making a big fuss, and the pipes looked quite sturdy.

"Hey, no matter how wise a woman is, there are times when she is confused!"

Song Xiaoshuang muttered to himself, walked over quickly, stared at Eliham who had a slightly puzzled look, and said quickly: "Didn't I hear Isabel say that the equipment here has been installed for at least a hundred years?" These metal pipes painted with anti-rust paint have been painted for a hundred years, the metal fatigue has been obvious, it is difficult to say how much external pressure it bears, I just looked carefully, there is no electrical equipment here, and there is no instrument, what does this mean, think about it? ”

"Well, there is no instrument to detect the pressure, which means that the designers who designed these devices have considered the pressure in advance, and the pressure caused by the medium in the pipeline is not very large, oh, I see, the pipeline is all groundwater with a small flow rate, and the whole system device is a large siphon device, the pressure is small, and there is no need for a pressure meter at all, then"

Eliham is, after all, the leader of a tribe, and her clever mind gives her good analytical and inference skills, and she blurts out a few words in Chinese.

"If you sit down, it is likely to break the balance between the already serious metal fatigue pipe and the pressure of the water flow in the pipe, once the pipe can not bear your weight and bursts, the siphon effect is likely to disappear, and the artesian well spring water on the ground will no longer gush out of the spring, suddenly interrupting this work process that has lasted for hundreds of years, it is not the most important, don't forget that it is the energy crystal that supports all this, and now put it in that mushroom head, you know that there is great energy inside the energy crystal, If the device fails due to a pipe rupture, will there be a large explosion with wide coverage? Don't think that this kind of thing won't happen, even the bridge designer has a design for the predetermined blasting of the bridge support point, and this device that uses energy crystals will not have a design to prevent damage from outsiders? Think about it, how could a designer not have a back hand! ”

Song Xiaoshuang's very stern reprimand shook Eliham's eardrums, Eliham felt a little chill on her body, but she was actually frightened by Song Xiaoshuang, as long as Song Xiaoshuang released a little coercion, she couldn't stand it.

Elliham even began to speculate that if she hadn't listened to Song Xiaoshuang just now, she insisted on sitting on the pipe and would have been slapped by Song Xiaoshuang with wizard ability, just like he threw Farhad into a pickup truck at a distance of more than ten meters yesterday, and no one in the vicinity at the time reacted, including Farhad himself, who shook out this detail when he was drunk last night.

"I, I haven't thought that far yet"

Eliham finally gave in, stammering and tears rolling in her eyes. She was afraid when she thought about it, if an explosion really happened as Song Xiaoshuang said, and several of her people hung up, not only would there be no drinking water source in the oasis, but no one would save the tribal villagers in the border refugee camp controlled by armed bandits!

As for the fact that the two siblings Maijid and Saeed often run here, it is fine, but in fact, their weight is not enough to crush the pipe and cause it to burst, and they are all children who weigh only a few dozen pounds. These simple truths were immediately figured out by Eliham after she came back to her senses.

"Well, that, Elliham you are also unintentional, so you don't have to blame yourself too much, I don't know how many years this device can last, let's go to the storage room where the energy crystals are stored, there are a few small folding stools to sit on, I will tell you everything I know, I hope you can keep it secret!"

Seeing that the atmosphere was not right, Farhad hurriedly said to ease up, and after Song Xiaoshuang heard Farhad say this, he had a strange look on his face, and walked to a stone passage in the back first.

His mental power detected that at the end of the other passage, Isabel was leaning down next to a sandy soil test field of several square meters, staring at a few pepper trees more than a meter high.

There is a shallow water tank on the stone wall next to the stone wall that is one meter long and only ten centimeters wide, the water in the sink comes from a metal water pipe the thickness of chopsticks on the wall, the water flow has almost no pressure, the water droplets drop by drop into the sink at a very slow speed to stir up ripples, a black square cylindrical energy crystal sinks in the water body of the tank, and several pillars of light gather together and project in the tank.

At the end of the passage, there is a stone chamber that has been excavated, and there are only a few pillars of light cast by metal pipes installed on the roof of the stone chamber, and the layout is barely visible in the stone chamber, with an Arabic-style tapestry hanging on the stone wall
