Violent airflow was pressed out from the four sides of the lifting platform, creating a roaring sound.
But the other four people didn't take it seriously and were extremely reassured by Shou Gong's calculation and control abilities.
Sure enough, as the four people felt that their bodies were gradually being pressed hard in place, the speed of the platform slowly decreased at a very linear speed, and finally stopped steadily.
Walking off the platform, there was a metal passage that was only a few dozen meters long. As the lights came on one by one, several people saw that at the end of the passage, there was still the same elevator as at the beginning.
"There are several times where we can transfer to the elevator like this." Shou Gong explained to the Ji siblings.
"Wow, how deep the base at the bottom must be!"
"It's not deep, just over 30,000 meters!" Ji Hai chuckled.
Ji Changshan sighed:
"It's amazing. The empire's infrastructure mining capabilities are so powerful."
Standing on the new lift and repeating the previous descent, Welling also felt a little emotional:
"Your Excellency, I just find it strange how the empire knew that there was a secret room deep in the ground below, and how it accurately located and built such a deep descent passage."
Dingguo Gongji Haifu's eyes were obscure and she smiled slightly:
"Yeah, I'm a little curious, but there is no corresponding record. Construction started after the establishment of the empire. In fact, it didn't take much time. More than ten large vehicles transported basic large-scale intelligent engineering equipment over in less than half a year. It's finished."
Wei Ling nodded. In fact, he felt a little regretful for asking this question. He shouldn't have asked.
This should be one of Ji's heritage. The royal family that is higher than the four great clans naturally has its own unique features.
"Actually, it is not difficult to dig and build this descent channel. What is the real difficulty, Chang Shan, can you think of it?"
Ji Haifu assessed the Third Highness.
Ji Changshan thought for a while and just gave a guess:
"I guess it will be difficult to build a geothermal power station underneath."
Welling shook his head, he had an answer.
Seeing Wei Ling shaking his head, the Ji siblings looked at Wei Ling.
"I think it is due to geothermal. For example, at the latitude of the Imperial Capital, two thousand meters underground, the geothermal heating rate will cause the underground temperature at that depth to reach 50 degrees Celsius.
Think about it, if you go 30,000 meters underground, if no corresponding cooling device is installed, the geothermal gradient will reach about 750 degrees.
Therefore, I think that the temperature we feel is very suitable now can only be due to the use of grand natural adjustments. For example, the lake water outside adjusts the temperature increase caused by the depth of the first elevator.
Then the subsequent cooling method must be to create a waterway that connects to the Arctic Ocean from the side, using the infinite circulation of cold ocean water to reduce the temperature of this channel, and separate a small part of the circulating water as an energy source for the underground power station . "
Ji Changshan and Ji Hubo were stunned. They had never thought of this problem.
Ji Haifu looked at Wei Ling approvingly. It was not surprising that Shou Gong knew all this. As a warlock, Wei Ling could even know these unpopular knowledge, so he was considered knowledgeable:
"Yes, Welling has revealed the key point. In fact, no matter it is Yaxi, Bohu, Imperial Capital, etc. in the empire, as long as there is an underground city in any large county, there must be a large water storage next to it for circulation to lower the ground temperature. , using such circulating water flow to generate electricity is actually enough to support conventional energy needs.
The controllable nuclear fusion device below is actually more for military preparation. After all, large-scale energy weapons require large amounts of energy in a short period of time. "
"Thank you, Uncle, for clarifying the doubts. Then, the ventilation system is also an important system project."
"Of course."
…
Unknowingly, they went through multiple elevators and reached the bottom passage.
The channel is an alloy tens of centimeters thick, with reinforcing ribs both inside and outside at regular intervals.
The ground was spotless, reflecting the cold light under the slightly dim overhead light.
By the sound of their footsteps echoing off the thick alloy walls, the geckos have built a three-dimensional model of the entire space.
Various devices in the passage, room orientation, size, material, spectral coefficients and other related data flashed through Welling's sea of consciousness like a waterfall.
In Welling's sea of consciousness, the entire area was transparent, and everything appeared in the form of outlines. There was only one position in the middle, a black cubic space with a side length of about twenty meters, without any information at all.
Cubic matrix space made of unknown materials.
Wei Ling nodded to the guard, indicating that he had received it.
This underground base is basically vacant. Even the manufacturing equipment in each space has been moved back to the underground space of the Imperial Capital. Each space is empty, without any garbage or remnants remaining. It is like a brand new preparation base. It seems to give people a very cold and scary feeling, although the temperature here is still controlled at more than ten degrees.
This relocation method suddenly gave Wei Ling a familiar feeling. Isn't the closed birth base of the Murong family on the unknown island near Huliang City in the endless ocean to the east similar to this style?
Soon, after several turns, up and down, we finished walking through this underground base. At the end of the passage, there was a black door.
Originally, the alloy walls and all the room doors were made of silver-gray alloy. This black door suddenly appeared at the end of the passage, looking so disharmonious.
The five people walked to the black door and entered the room next to it.
There was no one else in the room, but there were some seats.
"This is where people were stationed on duty for a short time after the base was moved. Later, it was deemed unnecessary, so we gave up. Only the entrance of the cave on the ground was left with more than a dozen sergeants stationed there."
Ji Haifu looked at the empty room and explained to the four people.
After walking for so long, Ji Hubo and Ji Changshan were a little tired, so they both sat down.
"Sir, is that secret room inside the black door next to it?"
"Yes, in fact, everything outside is built around this secret room."
"The knowledge that the empire had in the past was all brought out by Murong after he entered?"
"Yes, in fact, those technologies were developed through calculations based on a large amount of materials and physical objects brought out. There is no text or other information. Even after the high-quality intelligent body Liuli Body is successfully produced and placed in the cultivation tank inside, it is all the same. It’s a tentative experiment, more information is unknown.”
"So did you ever think about studying that black liquid?"
"I have, but I can't analyze its ingredients. Once it is taken out, it will dissipate and disappear in a short time."
Wei Ling nodded, guessing that the liquid was probably energy dissipated, so he continued to ask:
"What kind of magic or method did that person use to enter before?"
Ji Hai smiled bitterly:
"He has all five spirits. After many attempts, he used various spells. In the end, it seemed that he condensed five kinds of spiritual power in his hand at the same time. If he slapped it on the door, the door would dissipate for a moment."
Welling nodded and made a decision:
"In that case, I will try it right away to see the material of the black door and see if it can be cracked in the same way.
If possible, I will go in and take a look first. It would be best if I can bring out the culture tank. If not, I will bring out the liquid and let the two highnesses take a bath in a certain room. "
"Okay, you can try as you like. We have used all our abilities on the door without causing any damage."
Ji Haifu replied with a wry smile.
Welling walked out of the room and faced the black door.
This black color is very strange.
No matter what kind of black color, when illuminated by an external light source, the material will inevitably reflect light to a certain extent, revealing the blackness of different spectral coefficients.
But this door is different. It can be said that it absorbs all the light perfectly without any reflection, so it looks extremely dark.
It can be said that this kind of black is no stranger to Wei Ling. When Myrobalan pulled him into the world of Yuanling, the world his spiritual body felt was this kind of absolute darkness.
Wei Ling did not condense the five kinds of spiritual power in his hand, but directly turned one hand into energy, which looked a little gray and transparent.
When the hand was close to the door and only a few centimeters away, Welling's eyes narrowed.
He clearly felt that the surface of the door was fluctuating like liquid.
Where the palm is close, countless tiny protrusions protrude from the door, like dense fluffy tentacles, protruding in an attempt to get closer to the palm.
Welling mustered up his courage and put his hand on the door.
Wei Ling's eyesight dimmed.
The door in front of him had disappeared, and he strolled into the secret room.
The secret room is very empty. The four walls are made of the same material as the previous door. It is extremely black and has no reflection at all. There is only the floor and top surface. It feels like a black alloy material, and the surface properties can be seen.
The most amazing thing is that the entire ground is covered with a thick layer of dust, as if it has accumulated for millions of years.
Wei Ling took a step and frowned. With his own weight, he did not leave any footprints in the dust.
This is not scientific, unless the dust is not simple dust, but the debris of a high-density planet like a neutron star.
Wei Ling immediately felt the radiation value and was surprised that he didn't find anything special.
Then, he looked at the ship-shaped cultivation tank in the center of the secret room.
The slightly curved boats at both ends were also made of an unknown black material, with a black liquid in the middle.
The liquid was like black amber, deep and profound.
There was a slight sound behind him, like a breeze blowing behind him. When Welling turned around, he saw the black door appeared again, isolating the others from outside.
Wei Ling immediately felt it with his mental power. He could feel the situation of the other four people outside and felt relieved.
When the door is closed, the secret room will become a pure black space under normal circumstances.
However, the extremely dark wall began to become lighter.
In just one breath, Wei Ling regained his vision and felt that the walls and ceiling on all sides were emitting a faint light. It was not dazzling, but enough to reflect objects.
Wei Ling stepped forward, ready to explore the black liquid in the ship-shaped container.
By now, Welling was no longer willing to call this container a culture tank.
In his opinion, the cultivation tank should not look like this. He had seen many cultivation tanks at the base near Murong's Huliang City.
Although it was just a small culture device for studying tissues and genes, its appearance and various connected pipelines gave it a very technological feel, and it was definitely not such a simple black ship-shaped container.
He preferred to imagine it to be a coffin.
In ancient times, the ancients believed that the soul could reach the other side and needed to be carried on a boat. Therefore, the deceased was loaded with boat coffins and placed in the mountains.
When Wei Ling just took this step, he suddenly stopped.
The "stardust" on the ground actually moved automatically without wind.
