Behind the door, there is a very familiar scene of poplars, white brick and gray walls, and a very ordinary men's toilet.

He turned his head to look behind him, and sure enough, the long, deep corridor behind him had turned into a smooth toilet bowl and gray brick walls.

He poked his head out and counted the number of compartments on the right, one, two, three, four, five, this was the fifth, located in the innermost part near the entrance.

He's back.

"This path really doesn't work, do you really want to go into the black fog?" he sat on the toilet lid of the fifth compartment, his hands on his head, and his face was embarrassed, "Try again, maybe the result will be different?"

He didn't notice it himself, he had an inexplicable sense of resistance to the strange black fog that had been permeating the entrance to the toilet, and he didn't want to have any contact with it.

Under the influence of this sense of resistance, he still had a fluke mentality about returning to the mirror world through the reddish-brown wooden door of the alien dimension to find Mo Qiushui, and decided to try again.

After another complete excretion process, he pushed open the door, looked at the dark and damp environment of the different dimension, and took a step.

There was a hint of hesitation, some confusion.

About five minutes later, a reddish-brown wooden door appeared in his field of vision, and he didn't bother to check any fingerprints, so he walked straight forward, twisted the doorknob, and pushed the door open.

"Huh. He looked at the scene outside the door, tugged at the corners of his mouth, and let out a weird laugh.

He's back again.

He began to get anxious, walked out of the cubicle, and walked up and down the floor, nervously looking here and there, his expression also gloomy.

"Calm down, calm down. He kept chanting in his heart, trying to calm himself down with psychological suggestion, "Now it seems that I can only try to enter the black fog to find Mo Qiushui, be optimistic, maybe behind the black fog is a beautiful woman who has just taken a bath." ”

He suddenly reacted to something.

"Why do I always have resistance to this black fog? I don't have any contact or understanding of it, why is there such a rejection out of nothing?"

Suspicious, he began to carefully observe the black that was pervading for the first time.

The black fog is pervasive, from the edge to the inside of the color gradually darkened, the edge is a layer of light black, slightly transparent, there is a halo around the halo to blur around, the depth of the color is getting thicker and thicker, the deepest part can be said to be a little black and dazzling, but like staring at a ball of light.

As for the black that came through the gap in the ventilation window, it left a stripe of light and dark on the ground, and the most central stripe was a deep black.

Poplar looked at the stripes on the ground and fell into a trance.

"This thing, it seems to be called, interference stripes?"

In the real world, after the black mist rose to envelop the public toilet, Chu Qiu caught a glimpse of Yang Shu stepping into the men's toilet.

"Yajiu!" Chu Qiu shouted in the direction of the toilet.

"What, where is Yaku?" asked Rachel in a daze.

An Yi looked at the black mist that was gradually rising, and her face sank quickly.

While shouting, Chu Qiu hurriedly rushed to the toilet, but was blocked by the rapidly rising black fog, and the last step was not stepped out.

"Damn!" she scolded, slamming her foot on the ground in a fit of rage.

She turned her head to see An Yi's heavy expression and asked, "Qingxu, have you found anything?"

An Yi nodded slowly and said, "I think, I know the origin of the anomalous properties here. ”

"How many layers are you sure?" Chu Qiu asked.

"When I was a child playing in Master's library, I found an ancient book, and if the record in the book is correct, I am 90% sure," An Yi continued, "The name of that book is 'Records of Gods and Ghosts', and what is written in it is pure things like some strange ghosts and gods, such as the candle dragon who is 'regarded as day, eyes as night, blown as winter, called as summer, and the body of a snake with a human head and a snake body', and the corpse king and general who are 'born with the resentment of heaven and earth, immortal and immortal······ This book mainly talks about the life experiences of these ghosts and gods. ”

"What are the life experiences?" Rachel continued, "did they all die in the end?"

"Aren't these characters all legendary gods and demons, haven't the Federation verified that most of the myths are fictional? Why do you suddenly mention this? Chu Qiu said with a frown, a little impatient.

"Captain, I know the severity, no kidding. "An Yi's expression is very serious," Unlike the few and vague descriptions in myths and legends, this book records in detail the origin, experience, social relations, and cause of death of each ghost and god······ It's more like a canonical history than a strange novel. ”

Chu Qiu took a few deep breaths, regained his composure, and said, "I understand, I was too impatient before, you continue." ”

An Yi nodded, and continued: "There is a creature mentioned in that book, called 'Mirage', according to the book, Mirage comes from chaos, born from the evil of human nature, amorphous and amorphous, generally appears in the shape of a chaotic and unknown black light cluster, which can erode the space where it is located, and further distort the space through the negative emotions such as fear, tension, and anger in the hearts of the people who strayed into it, until it is separated from the real world, and it feeds on the space debris that is out of the real world. ”

"And how did it end up dying?" Rachel asked.

"He was burned to death by the Flint Clan's fire of the first life. An Yi replied.

After listening to An Yi's words, Chu Qiu's consciousness was connected to the federation's database and quickly queried some relevant information.

"I've just checked the information, and I haven't found any entries related to 'Mirage', and the Suiren Clan has no reliable information, but the Primordial Fire does have something. Chu Qiu opened his mouth and said, at the same time, his right hand was spread out, and a magic power formed a light screen, showing a picture.

It was a dead branch, and at the end of the dead branch, a handful of orange-red flames danced, burned, and faltered, as if they could be extinguished at any time, but they gave people a sense of eternal vicissitudes, just like millions of years ago, ape-man lifted a branch lit by thunder, and with awe and piety, he carried it out of the dark and wild African continent, and branded it all over the world as a unique human being.

On one side of the branch, there is a textual description.

“

Item No.: DCU-301

Item Name: The Primordial Flame

Item Description: DCU-301 was discovered in a fire pit in a cave near the ancient human remains of Xihoudu in the Yellow River Basin, and the appearance of the object is a cluster of branches burning at the end, a total of 12 branches, the branches are deciduous trees of the family Populus of the order Poplar, the poplar tree, with no special physical structure and appearance. The core temperature of the flame is about 341.23 °C, the temperature of the outer flame is about 871.23 °C, and the height is about 16.38 cm, which has a certain response to external physical stimuli.

Anomalous Properties: The object's combustion process does not cause any material loss, and there is no consumption of accelerants and combustibles, but it will continue to emit heat and light energy, which does not conform to the law of conservation of energy. In addition, the object's flames cannot be extinguished by any currently known means, and the intensity of the burn is always constant. In the existing observational records, there are two records of strengthening and two weakening of the flame, corresponding to the first industrial revolution, the second industrial revolution, the first world war, and the second world war, respectively, and it is speculated that the flame can reflect the rise and fall of the human race to a certain extent.

The object's flames can ignite all normal combustibles, such as paper, wood, silk, etc., and the ignited objects are unable to exhibit specific properties, and it is speculated that the object's anomalous properties cannot be inherited. In addition, the object's flames do no harm to purebred humans, but instead boost metabolism and increase affinity for supernatural energy. However, the subject's flames are extremely lethal to certain human-specific creatures other than humans or to humans, and can inflict mortal effects on organisms below Classification Standard III (Insufficient Clearance).

"If the Primal Flame is a real anomalous object, then why are the Flint and Mirage fictional, and what is the purpose of the person who wrote this book?" Rachel asked in confusion after reading the materials on the Primal Flame.

"Don't worry about this for now, now is not the time to gossip," An Yi realized some of the problems, but didn't dig deeper, and said, "Let's think about how to help Yajiu and them." ”

While the two of them were reading the information and talking, Chu Qiu stood aside, looking at the public toilet that had been completely shrouded in black light, his eyes were cold and he didn't say a word.

······

The poplar stared at the light and dark stripes on the ground, and after thinking for a long time, he suddenly had an epiphany and shouted: "I remember! This is the interference stripe, the interference of light!"

But in the next second, his excited expression turned into doubt: "No, isn't this black thing fog, how can it interfere?"

In his mind, an image slowly rose from the sea of memories.

A small ball of light emitting black light, floating on the toilet seat, the surrounding environment is gloomy, the position of light and shadow is reversed, and the darkness expels the light.

Thinking of this, some broken information was hooked up in his mind, and a clear picture scroll slowly spread out.

"It's not fog, it's light!" a look of confidence appeared in his eyes again, "The truth has been held in my hands." ”

Mid-2 +40

"Mo Qiushui, just behind this black light!" he walked confidently into the black light, and his figure was quickly engulfed by the darkness.

After entering the black light, the light in front of the poplar tree was instantly replaced by darkness, his vision was completely blocked, he couldn't see his five fingers, and he couldn't smell anything, it was really as silent as death, only his own heartbeat and breathing also reminded him of the existence of life.

In such an environment, he couldn't help but get nervous, lowered his heart rate and breathing, lightened his steps, focused on his surroundings, energy weapons appeared on the surface of his body, pulled out the wooden knife pinned to his waist, held the knife in both hands, and moved forward step by step.
