Blue Sword

The abyssal plane is dim and dull.

It is said that in the distant golden age of prehistory, shortly after humans colonized the planet Helel, they began to organize exploration teams in three major dimensions and established a large number of scientific research bases there. Therefore, a lot of scientific and technological information was lost in the three major planes, and fortunately escaped the invasion of the demonic tide in the main plane.

Most of the scientific information that humans have about the abyss today was recovered from the abyss by archaeological exploration and archeology by the ancient Solomon Empire during the third and fourth centuries.

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

However, the abyss is the other way around, with more matter and less space. The material that makes up the main body of the abyss is called "dark matter", which is highly stable and does not participate in electromagnetic interactions. Because the interaction with photons is very weak, dark matter itself neither emits nor reflects light.

Therefore, the abyss made of dark matter is always in darkness. Even if you turn on the flashlight and shine it on the dark matter wall, you can only see the dim light beam that stops abruptly on the wall, as if it is cut off at the waist. —The light pillar itself comes from the scattering of light by the air, but dark matter itself does not reflect light, so it appears to be 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 give everyone the ability to "listen to the sound and identify their position":

When a sound is emitted, the sound wave will propagate to surrounding obstacles and then bounce back. After being analyzed and transformed by the curse ability, the corresponding "scenery" will appear in everyone's mind, as if they saw it with the naked eye.

"Asker, who are we next?" Mi'er looked at the outline of the surrounding cave and asked with some worry.

"The Great Karst Cave is located at the bottom of the abyss. The further you go down, the more serious the erosion from the abyss will be." The Banshee King said quietly, "You should go up as soon as possible."

The so-called upward refers to the opposite direction of gravity. There is still gravity in the abyss.

Everyone looked around. On the left and right were narrow cave walls, either facing forward or backward. Which road led to the upper level of the large cave?

"Mi'er." Ask added, "Observe what the consequences will be in the future if you go forward or go backward."

Mia was stunned when she heard this. So this can still be done?

The Banshee King smiled and said nothing.

Mi'er nodded, and then began to observe.

Among the countless diverging world lines, 50% of the world lines lead to the front, and 50% of the world lines lead to the back. In other words, without any clues at all, everyone can only choose purely at random.

Continuing to observe further in the direction of the time dimension, she saw that in the forward world line, the height of the terrain was getting lower and lower; on the contrary, it was the backward world line. After everyone moved forward for about 4 hours, they suddenly saw a certain person. Personal man-made architecture.

Mi'er described it to him, and Asik immediately made a decision: "Go backward!"

So everyone turned around and moved forward. The passage of the large cave goes in an irregular direction. Sometimes it goes straight forward, sometimes it winds and snakes. Fortunately, there are no intersections along the way. After walking for a few hours, little Mia felt a little hungry.

As an undead, the Banshee King does not need to eat, and naturally Mia and others cannot. Ask asked Mi'er to pull out food from the past time from other world lines.

Maintaining matter from other world lines requires the spiritual energy in Mier's body to be consumed at all times. Once the spiritual supply is stopped, the material will disappear immediately - even if it is eaten.

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

Therefore, relying on Mi'er's ability of the Law of Destiny, everyone can barely survive for a few days without starving to death. Even more troublesome is thirst. After all, water is mainly involved in transporting substances in the body, and human skin and breathing lose water all the time. Therefore, everyone urgently needs to find a clean water source as soon as possible.

Of course, there are places in the abyss where you can obtain food and water, otherwise no players would come to play on this plane map. After fighting monsters for a long time, the character can't find water and dies of thirst. Isn't that funny?

After trekking in this direction for about three and a half hours, everyone indeed saw the man-made building Mi'er described.

To be precise, it is a door embedded in the cave wall - judging from the style, it is obviously a technological creation of human civilization.

Considering that karst caves are made of dark matter, human technology in prehistoric times can actually mine dark matter and build scientific research bases inside. The level of technology is truly amazing.

The outer door access control of this scientific research institute is not a swipe card, but is equipped with a code lock. The password screen was still on, apparently the power supply inside had not been interrupted. It’s just that neither the key card nor the password can be handled by everyone at this time.

If we consider it from a game perspective, it is impossible to design an inaccessible map, then the access code for this scientific research institute must exist somewhere nearby... or somewhere further away, anyway, it must exist.

But Asker is too lazy to think about this. He now has two plug-ins in his hand, one is called Mi'er and the other is called Mia. Why does he need to solve puzzles according to normal player thinking?

"Mia." Ask said, "Use your ripple sword to teleport us in."

"Oh." Mia agreed.

She was a little worried. After all, the first time she used the Ripple Sword, she was teleported to such a ghost place by mistake, which made her quite lacking in confidence at this time.

Mia carefully grabbed Ask, Mier and the Banshee King, and after confirming the displacement vector several times in her mind, she activated the ability of the Ripple Sword.

Immediately afterwards, the scene around everyone changed instantly, and they came to the other side of the gate.

The interior decoration style of this institute is obviously more retro and advanced than the last "Psychic Technology Institute" located underground in Runfield Town. The surface of the wall made of alloy material is full of streamlined circuit wiring and pipes. They are densely packed but distinct, giving people a strong aesthetic feeling of industrial design.

"Welcome." From the corner corridor in front, a synthetic man with a human appearance came out, emitting a mechanical and clear electronic synthesized voice, "Hello guest, welcome to the Abyss Research Institute No. 734, I am a research assistant Cape."

Mia and Mi'er put on a defensive posture at the same time, but the synthetic man codenamed Cappe on the opposite side had no intention of attacking them, and just continued:

"It has been 1784, 5 months and 27 days since the last evacuation of the institute's personnel. Since the institute's closure procedures have not been implemented, various facilities have been operating to this day. Have you brought any new authority orders? ?”

"No." Ask replied.

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

"Understood." The synthetic man said expressionlessly, "According to the management regulations, you are now granted the status of visitor."

"Is there anything to eat?" Asik continued to ask.

"According to the management regulations, we will provide visitors with daily necessities until the new management regulations change takes effect." The synthetic man turned around and began to walk forward.

Everyone quickly followed it and walked in the corridors and stairwells for about ten minutes before arriving in front of a certain warehouse.
