Just as Zeng Xing returned to their duty hut to look for it, the third layer of the Xuanwu 900 kilometers underground continued to be busy.

"Is the wire all right?" Zheng Kai took the walkie-talkie and stood on the high platform that had been erected, staring at the similar steel jungle in the distance, the iron shelves were as tall as bamboo, and the wires on the ground were crawling around like snakes.

"There is no problem, after many tests, the energy can be transmitted normally." After waiting for a few seconds, Xia Xiaoyan's hoarse voice came from the walkie-talkie, "Other departments have also debugged the equipment." ”

"Where's the backup pipe?" Zheng Kai asked, looking at the thick pipe with a diameter of 1.5 meters beside him, but then at the pure white light behind him that was almost like the background wall, he still subconsciously shook his head.

"More than 30 spare pipelines have been prepared, which is also a loss to Shen Zixuan's contribution to nuclear fusion." Xia Xiaoyan said, "The factory area on the second floor is constantly manufacturing transmission pipes, which can theoretically support the upward work for two years. ”

"Remember, close a vent every seven days and then do a month-long maintenance and inspection." Zheng Kai said, looking at Bing Shijue on the side, "I'll leave the start to you." ”

"No problem, it would be nice if we could have more immortal cultivators." Bing Shijue smiled bitterly, and briefly went through the plan made during this period in his mind. Ever since he and Zheng Kai had determined that there was an energy source inside Xuanwu, several seemingly dangerous tests had begun.

They tried to extract energy from this massive octahedron, but the most conventional methods failed, and some high-risk behaviors were proposed, but without exception, they were rejected. Because according to simple estimates, even if this octahedron explodes a little, then it is enough to overturn the entire earth.

However, in the face of such a treasure mountain, how to use it safely and carefully cause a series of problems has become the biggest problem that needs to be overcome this year. The good news is that after a few exchanges, the instrument decided that it was suitable for people to live, so a series of students and researchers settled here.

In addition, the light emitted by this octahedron was completely harmless after testing, and more similar to the sun's rays, so some small rice fields began to be planted here. This also leads to a very strange arrangement, with eight different areas centered on the octahedron. Four of the areas and the four corners of the cube are on a spur line that serves as the area of study.

The other eight areas became the planting areas. They brought a lot of soil and water from the ground and began to plant.

It was also the first time that Bing Shijue knew that he could still put such common things in soil and water life in his sea of consciousness, but the seeds were not good, and there was still a chance of withering after putting them in.

The most important thing is that the distance of about 3,000 kilometers is enough for people to find a place to live with peace of mind, as well as a place to conduct scientific research. It's just that for the sake of safety, seventy percent of scientific researchers still live on the ground. Only Sancheng came to work in Xuanwu.

After Bing Shijue's investigation, he also basically understood that Xuanwu was divided into three layers, at least on the surface, this was the limit of what he could explore. Because the divine mind is suppressed, it can only rely on vision and flight time. At the bottom are the octahedron that radiates light and the hexahedron at the four corners. The second level is the residential quarters, and the top floor is completely empty, with only a few weapons similar to the Mining Gun remaining.

However, the excitation method is the same, using the energy of the spar or the life form itself as the drive, but the effect and power will be much greater.

After these points were determined, the crowd on the ground began to move in one after another for testing. Test whether the second or first floor can be inhabited and lived in the absence of a light source.

The result is delightful, as the population of 300 people living on the second floor begins to glow warmly above the head and on the ground, and this light automatically adjusts and changes 24 hours a day. This move has also led researchers to speculate that it may be triggered after sensing a certain number of people, or a certain weight.

However, considering that too many people may open more functions, and this function may consume the energy of the octahedron underground, after careful consideration, the number of people living on the second floor of Xuanwu has increased to 9,000 people, and some factories and shops have begun to be built to meet people's living needs.

The first layer of Xuanwu is used to stack all kinds of materials, and after Zheng Kai and Bing Shijue discussed together, they asked Bing Shijue to stack most of the resources on the first layer, so that he didn't have to move around, because it took too much energy to bring many people down before.

With enough reserve resources, a fusion device that has shrunk to the size of a house, and enough manpower, research on octahedron is in full swing.

Unfortunately, after all kinds of impacts, explosions, and chemical corrosion, there was even a risk to get everyone away, using a dozen mining guns to attack, but it didn't affect the octahedron in the slightest. But when people bathe in it naturally, they can feel warm and plants can grow. Or when people are close, the body will also be full of very warm and natural energy.

This attempt also gave the third-level research team mixed information, the good news was that the octahedron was unusually stable, and the conventional methods of humans could not harm it at all. The trouble is that energy can only be transmitted by means of close proximity.

So according to this, the scientific research department has created an energy negative pressure pipeline. The principle of the pipeline is very simple, at the junction of the pipeline and the octahedron, a high-energy and high-consumption computing device is installed, and this computing equipment is connected to the computer of the scientific research department. As a result, there is a lot of energy consumption and vacuum at the front of the pipe.

Combined with the properties of the octahedron, the abundant energy will flow into the pipe like a stream of water, so that the energy can be transmitted to the octahedron in the distance.

The back pipe has also undergone a new design, a negative pressure pipe interface has nine small computing devices, as well as a runner and heat dissipation equipment, so that it can dissipate heat in rotation, while rotating, increase the efficiency of energy improvement, and in order to reduce the interference of cables, it also basically uses the function of wireless information transmission.

In the end, it was by mistake that they recruited the highest power generation method at present.

Hit each other with hedron and hedrons.

That's what happened during the docking test, because to create a negative pressure of energy, you had to use small spar chips to consume the computing device first, and then connect to absorb the energy.

Unexpectedly, because the worker in charge of the operation was too close to the octahedron, sweat got into his eyes, and his hands trembled slightly. The powder touched the octahedron with a slight shake of the fingers.

At that moment, the pipe in his hand directly burst open, and the nine computing devices were also directly burned.

Luckily, the workers in charge of the operation were wearing heavy protective gear, so he was just knocked to the ground, his head touching the octahedron, and the energy flowed into his mind, allowing him to instantly understand what had just happened and how to modify the energy transmission pipeline.

In this way, the last piece of the puzzle of the second plan was put together, he made up for it and became the leader of the group, and the plan of Xuanwu's ascension was successfully shortened from the original 10 years to one and a half years. It's just that the energy consumption has been changed to the energy crystals in the Ice Initiation Spaceship.

According to their estimates, 1 cubic meter of energy crystal and octahedral collision can maintain a high energy output for 24 hours. But thanks to the Ice Awakening, the spaceship was able to produce 21 of these hedrons a day, enough for people to use for a long time.

"Xuanwu, it's finally about to start floating." Ending his brief memories, Bing Shijue took out a huge spar from the sea of knowledge space and put it on the mechanical arm. Then he glanced at Zheng Kai at his feet, he was wearing heavy sunglasses, and when he nodded to him, he also sighed silently.

"Sigh for what?" Bing Shijue asked.

"Sigh, what will we do without the sun?" Zheng Kai raised his head and said.

"At least for the next forty years, we always have." Bing Shijue said, his body began to float, and he also began to carry out his plan, coming to the lower mantle to help Xuanwu empty some of the heavy stones and increase the efficiency of the floating.

Suspended in the air, leaving the energy layer of the third layer, Bing Shijue flew to the residential area of the second layer. If it weren't for the fact that he could see the glowing zenith, the people who lived here would give him the illusion that this was not a Xuanwu, but some ordinary place of life.

It's noon, and it's the day when Xuanwu is about to rise. But these people are coming back from distant factories one after another, coming to their homes to eat piping hot noodles and porridge. Some foreign workers were nibbling on bread and habitually munching on side dishes placed on dishes.

"People's future lives will start here...... Bing Shijue glanced at those who were eating with their heads down, and also noticed that some people were waving at him. In this regard, Bing Shijue also nodded slightly, and quickly flew outside the Xuanwu. With a dull bubble crackling, he bent his back against the pitch-black basalt and faced the blinding, red-like magma, ready to go.
