The corridor of light and shadow hides the reality, and the fantasy is shattered and the dream is not awake.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~

A tunnel made of bones of dead creatures, the entrance of which has disappeared without a trace.

"It can't be a memory error." Xinglan clutched her black hair in distress, "There's absolutely no way I'm going wrong with my memory bank, and besides, the recording device inside this robot's body also clearly records all the movement routes, this is definitely the place I just came in." ”

Xinglan slapped her feet and slowly swam to the place where the hole should be, she frowned and looked at it, but she couldn't see a trace of discordant gaps, and she reached out and knocked on it, which was completely substantial.

Strange, could it be that this bone cave really can't run on its own long legs? Recalling the soft, unidentified object that had wiped her hair in the tunnel before, Xinglan felt a sense of unease welling up in her heart.

Unlike all the dangers encountered before, this time it was not that the enemy was strong, but that everything happened too strangely.

Calm down! Calm down! Xinglan kept reminding herself in her heart that all the strange things that happened this time would definitely be able to find a scientific explanation.

Finding nothing here for a while, Xinglan swam back to the pile of carapace fragments, carefully picking up a piece and looking at it.

The Glow Sea Scorpion is one and a half meters in size, which can be regarded as a considerable scorpion. These are only fragments of a carapace, but they are also quite large. The jade-like carapace is infested with fluorescent bacteria, and although it is a scorpion carapace, this carapace fragment is actually quite beautiful...... At least according to human aesthetics, it is crystal clear, and it can definitely be called a natural work of art.

The smooth carapace is not stained with dust, and there is a kind of beauty that comes out of the mud without staining, to be honest, Xinglan has an urge to use it as jewelry...... Well, when the time comes, let the underwater robot collect some more samples of the glow sea scorpion.

Even the carapace of a dead sea scorpion is enough to say a lot. Xinglan chuckled softly, turning the light-emitting element in the center of her palm to the bright light mode, aiming at the shattered carapace.

"This dense tooth scar...... It should be a large number of gnawing marks, most of which are distributed in the fracture opening, and there are almost no bite marks on the carapace of the non-fracture opening? Xinglan examined the different fragments in the white light, "There were no dents, no signs of impact, and the active tissue inside was completely gone......"

After examining all the fragments here, Xinglan made a rough judgment about the situation: "There are no signs of battle on the Glow Sea Scorpion, it should not have been killed head-on, it is most likely that it was trapped here, starving to death." As can be seen from the dense bite marks, the organisms that eat it are not large in size, and they should live in groups, and they will work together to bite the outer carapace of the dead organism and then eat the active tissue inside. ”

To put it simply, there are no super monsters here, on the contrary, it should be a group of small guys, but this method of trapping the prey and starving it to death is quite troublesome.

"But a single creature is unlikely, there should be a variety of creatures inside the cave here, but the strangest thing is here, why can't I find any living creatures until now." Biting her fingers, Xing Lan thought with some distress, "With our reconnaissance methods, it should be completely useless to protect the color or something, right......?"

Sure enough, should we try to find those mysterious little creatures first? Thinking like this, Xinglan once again set her eyes on the dense passages on the walls of the huge cave, well, go and take a look.

……

There didn't seem to be much difference between the different passages, and this time Xinglan chose the passage at random was almost exactly the same as the inside of the previous disappearing passage, but when Xinglan walked along the narrow passage for a few hundred meters, she found the end of the place.

"This is absolutely unscientific!" Xinglan almost had the urge to cry when she looked at the huge underwater cavern in front of her, which was exactly the same as the one before...... No, Xinglan looked at the pile of glow sea scorpion's carapace fragments on the ground in shock, and compared the data in the memory bank, and finally confirmed that this was the cave from before!

"Strange, but returned to the same place even though there was no turn?" Xinglan was a little overwhelmed, looking at these honeycomb-like dense holes in confusion, "Could it be that this place is really haunted?" ”

Xinglan, who did not give up, did not hesitate to pick a hole again and swim in......

……

A few hours later......

In the huge cave of bones, a girl fell to the ground in a frustrated forward posture, and her mouth kept muttering to herself: "How come...... How so......"

It's completely useless, no matter which passage you choose, you'll eventually return to this cave, and you'll come out of the place you entered. Even if there may be subtle bends in the tunnel, but there are no forks in the road at all, how can it be possible to return the same way?

“…… It's not scientific! Xinglan cried and looked at the pile of glowing sea scorpion carapaces intact, because of the long time since they had been dead, although these carapaces were still crystal clear, the brightness of the fluorescence was obviously decreasing, "Could it be that this is an infinite space-time corridor?" Could it be that the space here is distorted in a higher dimension? It shouldn't be so advanced......"

Woowoo...... The terrible sound of water wailing in the cave, combined with the eerie biological skeleton cave walls illuminated by the white light, Xinglan was inexplicably a little panicked...... Isn't it a little bit scared!

"Could it be that this is ......" Xing Lan remembered the information on the earth she had collected earlier, "The bottomless pit of the White Bone Spirit?" ”

…… Anyway, the bottomless pit is obviously a rat spirit!

As if thundered by her own thoughts, Xinglan stood up, floated in the water, and slowly swam to the side of the cave wall.

"Hmph, this nasty thing......" Looking at the messy bones on the wall, Xinglan puffed out her face in anger and reached out to grab a protruding bone spur......

Eh...... Didn't catch it?

Blinking suspiciously, Xinglan reached out again, this time successfully grasping the bone spur, but ...... Looking at the bone spurs that were not quite the same as the actual location, Xing Lan narrowed her eyes slightly: "Ah, so that's the case......"

As soon as he pulled it out, the bone spur he grabbed in his hand was pulled out, but the bone spur in his eyes was obviously slightly offset from the sensation coming from his body...... The offset is not big, just a few centimeters, but it does have an offset.

"What a shame...... the girl looked up, her dark eyes and long black hair fluttering in the sea inexplicably adding a blackened aura to her, "No wonder she can't find an exit...... Optical interference, illusion? ”

This illusion ...... Even the infrared rays are interfered with!

"The existence of a mirage, the undersea labyrinth created by optical projection, indeed, even if you know that what you see is illusory, you can't get rid of it, but ......" Xinglan floated in the water, closed her eyes, and opened her mouth slightly, "I don't believe you can even simulate this......"

The water in front of Xing Lan trembled violently, and a silent high-frequency fluctuation quickly rushed in all directions!

Ultrasonic positioning!

Although her eyes were closed on the surface, Xinglan's mind was rapidly processing the large amount of information received by her auditory receptors......

The slightly open mouth constantly emits ultrasound waves, which bounce back on the surrounding cave walls and are re-received by Xinglan, who then draws a complete three-dimensional image of the cave.

There is no color, but everything shows its truth.

"Original...... So. Xinglan closed her eyes, showed a wicked smile, and suddenly stretched out her hand to grab it......

"Caught!" With both hands, Xing Lan pinched the spherical creature with a diameter of about ten centimeters, but it was completely impossible to see with optics, ignoring the other party's frantic struggle.

In terms of strength, this little guy is obviously not comparable to Xinglan with the robot body at all, and can only soften weakly after a frantic struggle, and let it be ravaged. ......

"Although the personality is bad, it's cute......" Xinglan turned her body with her eyes closed, and felt with satisfaction that many of the same spherical creatures around her retreated in horror, "Well, cuteness is justice, so for the sake of justice, let's forgive you for your previous rudeness~"

After finding the right direction, Xinglan easily studied this strange spherical creature. The creature resembles a ball of flesh and moves by spraying water through tiny holes in its body, and its surface is covered with light-sensing cells. Unlike ordinary color-changing organisms, their color-changing is not achieved by regulating skin pigmentation, but by projecting luminescent cells in the body on the surface of a translucent body...... They can even cast this light onto the outside world, creating a fantasy-like effect.

"Well, this mirage-like scene is projected...... Let's call you mirages. Xinglan opened her eyes again, and when she looked closely, she found that the scenery around her was always misaligned, but this change was too small, and even the machinery was directly corrected as a data error, "Because I have been trying not to touch the wall before, I didn't notice it?" ”

In the ultrasound image, the entrance to the cave where Xinglan came in was still there, and Xinglan hit the wall because the whole scene had already rotated at that time, and the place she went to was just a wall on the side.

Of course, a mirage beast does not have such a great power, and it is impossible to make such a perfect projection, but a large group of mirages can create an illusion that even Xinglan is confused.

Then, the mystery is revealed~

The mirages whispered in fear, they only relied on this ability to starve the strayed to death before they dared to come forward to forage for food, but in terms of positive combat effectiveness...... I can't even run away with that size!

chuckled again, and stripped a bit of skin from the mirage in his hand as a genetic sample, Xinglan didn't embarrass it too much, but let it go.

As if understanding that the one in front of them was completely unopposable, the mirages let out a low cry and took the initiative to unravel the optical camouflage together...... If you want to go, go quickly.

Looking at the group of transparent strange creatures in front of her, Xinglan was also satisfied, flapped her legs, and swam towards the passage where she came, her sensitive hearing had already heard the chirping of whales in the distance...... Ah, are you calling for us to hurry back to the team?

……

Back in the sunny waters, Xinglan turned to look back at the deep hole on the reef island, who would have thought that there would be such a magical creature in this gloomy world? It seemed like a good trip......

Wait a minute! Seems to have forgotten something......

Xinglan reached out and stroked her hair, recalling the memories, the touch of the mirage just now and the touch of the thing that had brushed her hair before...... Seems very different?

Seem...... That thing, not a mirage......

The girl's face stiffened suddenly, and she looked silently at the entrance of the cave, the pale walls of the cave were still covered with white bones, and there was a faint mournful wail from inside...... Woowoo......

Mirages don't have the ability to simulate sounds...... Ha...... Ha ha......

With a dry laugh, Xinglan did not hesitate to swim towards the mother and child of the whale above, definitely don't stay here again!

As for what it was that brushing through the hair...... I, I don't want to know at all! It's not because I'm afraid!

……

The long-shaped creature named the cave worm by later generations hangs fixed on the cave wall at one end, and it twists the other end of the body without fixation, ah, the life of filtering organic matter directly from the sea water is really leisurely......

However, it seems that you hit something when you shook it just now? Slippery, a little bit of ...... Hawkers, anyway, the mirages didn't take back the illusion of hiding here, as long as we take care of our own door curtains, and from time to time issue an alarm for the entry of alien creatures for the mirages inside, we will fulfill our duty of symbiosis.

That's right, just be on the safe side! Details or something, only (9) will care about it~
