Lang Tianya sat on the deck and looked up at the large ball in the sky with a diameter of one kilometer, feeling the direction of the aura around it. Xindu stood next to Lang Tianya, also observing the sky with his hands behind his back. Because his right arm was broken, he had been wearing his iron arm of internal force alloy. With this iron arm, he can use his right hand at will while driving internal forces without worrying about the injury of his right hand. A small man with a dark and thin Southeast Asian face stood at the top of the bow of the ship, and was firing reconnaissance and detection talismans with open arms into the large ball, and a group of experimenters were operating various instruments to make observations.

They were on a small cargo ship heading for the northern coast of Alaska. The ship was flagged with Panama. This is a new type of jet cargo ship that can reach an average speed of more than 70 kilometers per hour. It was secretly leased by Neverland three days ago, and after a simple secret modification, it was loaded with different experimental materials at various ports in China and South Korea, and then entered the Pacific Ocean.

After Lang Tianya left the anti-monster base, he remembered that he had called Gu Bao over when he was talking to Guo Songshan. So he flew all the way to the southwest, while using the game earbuds to contact Gu Bao, asking for his general location, and at the same time releasing all the aura needles for detection. He also adopted a zigzag flight path during the flight, searching back and forth in the air. Finally, in the Pacific Ocean surrounded by Bering, he found the lonely treasure who was rushing to the northeast.

After he stopped Lone Treasure, he used the game earbuds to contact Ryan. Through communication between the two parties, he knew that the experimental ship of Neverland had departed, so he took the lonely treasure to search in the Pacific Ocean, and finally found the ship of Neverland. After the two of them got on the ship, they began to cooperate with them in experiments. So far, they have completed several small experiments in the early stage.

This morning, as the cargo ship was about to enter the restricted area, Xindu couldn't wait to take out a metal ball the size of a bowling ball and hand it to him, asking him to try to open it. He said it was an important experiment that had to be carried out at the junction of the exclusion zone. So Lang Tianya tried to use various operators in his body to manipulate this metal ball. Reliability began to arrange and arrange various observation instruments around him. Lang Tianya tried all the manipulations, including the various manipulation powers he had recently learned, but unfortunately none of them had any effect on it. In the end, he tried to modify the program of turning on and off the liquid crystal, and let the internal force retrograde this program, but he didn't expect this new program to produce a new kind of runic power, and he accidentally opened it.

But the way this metal ball opened was not the bloom of the bright body he expected, but a kind of expansion of the dark world. In the eyes of a person like Credibility, nothing has changed in this metal ball. But in Lang Tianya's eyes, countless liquid crystal particles in this metal ball that were originally closed appeared in a hidden state and were "opened". And they didn't become a pale blue semi-liquid crystal ball in the bright world, as he thought, it seemed to be opened "backwards", it bloomed in the dark world, and the state of appearance was like what he saw in his eyes now, becoming a large cage with a diameter of one kilometer. It turns out that liquid crystal particles can also be "opened" in this way, and this discovery alone makes Lang Tianya feel worthwhile.

Then, according to the requirements of reliability, he tried to drive the big ball, and encircled the lonely treasure flying above the ship to play inside. After the reliability experiment, he will ask Gubao in detail how he feels inside, and say that this is also an important step in the experiment.

The outer layer of the big ball in the sky is a large web of filaments composed of liquid crystal particles blooming in the dark world, and the mesh is hexagonal, each the size of a paper cup, densely distributed on the surface of the big ball. In Lang Tianya's eyes, the barrier of the colorful aura on the surface of the big ball makes the inside and outside of the sphere clearly distinguished, and it is clear at a glance. Through these meshes, you can also clearly see the huge figure of the lone treasure after being flattened inside the sphere, just like a huge eel soaring in the sky, hovering back and forth inside.

"Can you really see it?" Reliability asked.

"Yes." Lang Tianya replied as he observed.

"What does it look like?"

"Have you ever seen one of the big wire cages that zoo birds have?"

"I can imagine that."

"This one looks like the cage at the zoo. It's just that it's transparent. And it's bigger, more rounded, and doesn't have a base. In this sense, it's a bit like a balloon. ”

"It's amazing! I can't see anything. It's really more popular than people. Can you tell if you saw it with your eyes, or if you felt it with some other special ability? ”

"I felt like I saw it with my eyes. I could even see the aura particles flowing around it. ”

Xindu imagined that picture for a moment, and felt that it was not quite right, so he retorted: "What you said is not necessarily right. In general, the so-called vision seen by the eye is the sensation produced by the stimulation of the nerve when the light reflects on the object, and then enters the eye to excite the retina. But is it really the reflection of light on the aura particles of the dark world that you are 'seeing'? I'm afraid not. If so, today's instruments should be able to measure these rays. Isn't that aura particle an observable? But the reality is that aura particles cannot be observed by any means at the moment. So I don't think you're actually 'seeing', but detecting it with a special ability similar to vision. ”

"Then I might be seeing the dark realm of 'light'." Lang Tianya joked.

Xindu tried to think about it for a while, but he still couldn't understand what it was like to "see" at this level.

"Since you can see the flow of aura in the dark world, what do you think of the dark world? There is a popular hypothesis in the theoretical community that the dark world is actually the fourth dimension of this world. Do you think it is? ”

"I don't have a lot of theoretical knowledge. I don't know what the fourth dimension should look like, so I can't say if the dark world is the fourth dimension you think it is. ”

"Can you describe what the dark and light worlds look like to you?"

Lang Tianya thought for a moment and said, "If it were an analogy, I would say that the two seem to be in an overlapping state, but they are not simply superimposed, nor are they isolated inside and outside like a mirror. On the surface, they do not interfere with each other, but under special circumstances, the matter seen in the bright world can be transferred to the dark world, and the matter in the dark world can become visible in the light world, and the light and dark matter can be transformed into each other. There will also be an exchange of energy. The feeling is subtle. The closest adjective I can think of to this feeling is 'if or leave'. ”

Reliability is once again mired in imagination. After a moment he spoke again, "I don't feel like a truly complete fourth dimension. The fourth dimension I imagined should be more three-dimensional, and it should be that countless worlds overlap each other, not just light and dark worlds. For example, from a point to a line, a line is made up of an infinite number of points. And by lines and surfaces, surfaces are also composed of countless lines. The same is true of three-dimensional space, which is made up of countless faces. The fourth dimension should also be composed of countless three-dimensional spaces. The dark world may only be one of many spaces at most, and if we can discover countless dark worlds, then we can truly discover the fourth dimension. ”

"You mean the theory of parallel planes?"

"It's not. The fourth dimension is supposed to be in a plane, but it is composed of countless three-dimensional spaces. ”

Lang Tianya stared at a certain point in the void and thought for a while, and found that he really couldn't understand. He couldn't help but shake his head.

Xindu laughed when he saw him, and then he sighed: "You have such good conditions but you don't intend to conduct theoretical research. We, the researchers, don't have your ability. What an injustice! When will I be promoted to the Nether Realm, it's really enviable. If I were now in the Nether Realm and could see the changes in the aura of the dark world with my own eyes, it would be great for those of us who are engaged in theoretical research. At least it's a lot easier to experiment. ”

Lang Tianya glanced at his credibility with envy on his face, and couldn't help but correct him: "You may have some misunderstandings. It's not that when you reach the realm of seclusion, martial artists can see the aura. After entering the secluded world, the martial artist will look into the card position of his dark domain, which is also the beginning of the martial artist's real self-improvement and self-cultivation. But they don't see the aura of nature anymore. The reason why I can see it is completely my special ability. ”

"It's nice to only be able to see your own card slot! You don't know how painful it can be for researchers to experiment without a good means of observation. That's just half the effort. ”

"What the hell is this big ball for?" Lang Tianya asked.

"Zhang Fei said that it is a tool to deal with the Soul Eater." Reliability answered Lang's question.

"Zhang Fei gave this thing to you?"

"yes. She arranged this experiment. We're just doing it for her. The final data and results will be passed on to her. I guess she's probably not just working with us, she's probably working with multiple research institutions around the world at the same time. ”

Lang Tianya didn't speak again. He looked up at the big ball and the lone treasure inside, and felt that this thing didn't look like it was used against individual soul eaters. Just like now, if the lone treasure wants to come out of the big ball, it can easily fly out without any impact. At present, he still can't guess how Zhang Fei will use a big ball.

By this time, the ship was already approaching the restricted area.
