The abyssal plane, bleak.

It is said that in the distant prehistoric golden age, soon after humans colonized the planet Helel, they began to organize exploration teams in the three major planes, and established a large number of scientific research bases in it. Therefore, a lot of scientific and technological materials were lost in the three major planes, and they were lucky to escape the invasion of the demon tide of the main plane.

Most of the scientific data about the abyss of mankind today was also recovered from the abyss by the ancient Solomon Empire during the Tertiary and Quaternary periods.

The universe where the main plane is located is less matter and more space. For example, the radius of the planet Helel is just over 6,000 kilometers, and the distance from the planet to the sun is 150 million kilometers, and the 150 million kilometers are almost entirely void without matter.

However, the abyss is the opposite, with more matter and less space. The matter that makes up the body of the abyss is called "dark matter", DarkMatter, which is highly stable and does not participate in electromagnetic action. Due to the very weak interaction with photons, dark matter itself is neither emitting nor reflecting light.

Therefore, the abyss composed of dark matter is in the darkness all the time, even if you turn on the flashlight and shine it on the dark matter wall, you can only see the dim light pillar on the wall, as if it was cut off by the waist - the light pillar itself comes from the scattering of light by the air, but the dark matter itself does not reflect light, so it is pitch black to the naked eye.

Such optical properties make it difficult for the naked eye to function in the abyss. Fortunately, sound waves can still be reflected, so the Banshee King used the curse ability to temporarily gain the ability to "listen to the voice":

When a sound is generated, the sound waves travel to the surrounding obstacles and bounce back, and through the ability to curse and transform, the corresponding "scenes" will appear in everyone's minds, as if they were seen with the naked eye.

"Asker, where are we next?" Mi'er looked at the outline of the cave around her and asked with some concern.

"The Great Cave is located at the bottom of the abyss, and the further down you go, the more severe the erosion from the abyss." The Banshee King said, "You should go up as soon as possible. ”

The so-called upper is the opposite direction of gravity. There is still gravity in the abyss.

The people looked around, and there were narrow cave walls on the left and right, either facing forward or backward, which path led to the upper level of the great cave?

"Mi'er." Asker added, "Observe what the results of going forward and backward will be in the future. ”

Mia was stunned when she heard this, it turned out that it could still be like this?

The Banshee King smiled beside him without saying a word.

Mi'er nodded, and began to observe.

Countless divergent world lines, 50% of the world lines lead to the front, and 50% of the world lines lead to the rear. In other words, in the absence of any clues at all, everyone can only choose purely randomly.

Continuing to look farther into the time dimension, she saw that the elevation of the terrain was decreasing in the world line ahead. Instead, it was the world line that went backwards, and after everyone had advanced for about 4 hours, they suddenly saw a man-made structure.

Miel described it to him, and Aske immediately decided: "Go back!" ”

So everyone turned and walked forward. The passage of the large karst cave is irregular, sometimes straight forward, sometimes meandering, but fortunately there are no intersections along the way. After a few hours of walking, Miya felt a little hungry.

The Banshee King, who is an undead, does not need to eat, and Mia and the others naturally cannot. Asker asked Mi'er to pull food from the past from other worlds.

Sustaining matter from other worlds requires the constant consumption of the spirit in Mi'er's body. As soon as the spiritual supply is stopped, the substance disappears immediately—even in the stomach.

But if the food is digested and broken down into waste and energy is released, then stopping the spiritual supply will only remove the waste and will not deplete the energy that has been absorbed by the body.

Therefore, relying on Mi'er's ability to the law of fate, everyone can barely survive for a few days without starving to death. Even more troublesome is thirst, after all, water is mainly involved in the transportation of substances in the body, and human skin and breath are losing water all the time, so everyone urgently needs to find a clean water source as soon as possible.

Of course, there are places in the abyss where you can get food and water, otherwise there would be no players to play on this dimensional map. After fighting monsters for a long time, the characters themselves can't find water and die of thirst, isn't that funny?

After a long journey in this direction, after about three and a half hours, the group saw the man-made structure described by Mier.

To be precise, it is a door embedded in the wall of a karst cave - looking at the style, it is obviously a scientific and technological creation of human civilization.

Considering that the cave is made of dark matter, it is amazing how high the technology of human technology in prehistoric times was able to excavate dark matter and build a scientific research base in it.

The exterior door of this research institute is not a card-type access control, but a combination lock is installed. The password screen is still on, and it is clear that the power supply inside has not been interrupted. It's just that neither the key card nor the password can be handled by everyone at this time.

If from a game point of view, it is impossible for the planner to design an inaccessible map, then the access code of this research institute must exist somewhere nearby...... Or somewhere further away, it must be there anyway.

But Aske didn't bother to think about these at all, he now has two plug-ins in his hands, one is called Mi'er and the other is called Mia, where does he need to solve the puzzle according to the normal player's thinking?

"Mia." Aske said, "Use your Ripple Sword to teleport us inside." ”

"Oh." Mia should be down.

She was a little apprehensive, after all, the first time she used the Ripple Sword, she was accidentally teleported to this kind of ghost place, which caused her to be quite lacking in confidence at this time.

Mia carefully grabbed Aske, Mi'er, and the Banshee King, and mentally confirmed the displacement vector several times before activating the ability of the Ripple Sword.

Immediately after, the scene around the crowd changed in an instant, and they came to the other side of the gate.

The interior decoration style of this research institute is obviously more retro and high-end than the "Psychic Technology Institute" under the small town of Luenfeld last time. The surface of the wall, which is made of alloy materials, is full of streamlined circuit wiring and pipes, dense but distinct, giving people a strong aesthetic of a certain industrial design.

"Welcome." From the corner hallway in front of him, a synthetic human with a human form came out, and a mechanical and clear electronic synthesized voice came out, "Hello guests, welcome to Abyss Research Institute 734, I'm Research Assistant Capet. ”

Mia and Mi'er put on a jealous defensive posture at the same time, but the synth codenamed Capet on the other side had no intention of attacking them, and just continued:

"It has been 5 months and 27 days since the last evacuation of the last institute personnel, 1784. Since the closure procedures of the institute have not been carried out, the facilities have been in operation until now, do you bring a new order of authority? ”

"Nope." Asker replied.

If he obtains the identity ID card or password of the researcher here through a mission or exploration path, he can also try to deceive the other party and seize control of the entire research institute. Since he didn't, he could only honestly admit it.

"Understood." The synth said with a blank face, "In accordance with the regulations, you are now granted the status: Visitor. ”

"Is there anything to eat?" Asker continued.

"In accordance with the regulations, we will provide our visitors with the necessities they need until the new regulations come into effect." The synth turned around and began to walk forward.

The crowd hurriedly followed behind it, walking in the corridors and stairwells for about ten minutes, and then came to a certain warehouse.
