His spatial thinking skills are quite good, and even if he doesn't deliberately memorize them, he can find his way through the darkness based on his impressions. Along the way, they still didn't run into anyone else, as if they were the only two living creatures in this underground world. The sound of footsteps echoed in the empty walking paths, and the shadows in the empty shops were ghostly, and the gloom was overwhelming.

"Walk over here...... Then go up the escalator on the right and we will go to the B1 floor. ”

Just as Ichikoto was carrying Mikoto Misaka through the emergency stairwell connecting the two areas, there was a slight commotion behind a door at the corner of the staircase behind him—a door for unknown purposes. It was obviously not the sound of human walking, whether it was wearing sneakers, casual shoes, leather shoes or other things, it would not emit such a fine crawling sound.

It sounds like a rat in a documentary — but it's hard to find a foothold in a place like the underground where small cleaning robots are widely used, let alone the swarms of rats. But if it wasn't the rats that made the sound, what would be this commotion coming from the unknown space behind the door?

He suddenly felt extremely panicked, and the girl who touched his arm trembled slightly, and the palms of the two holding each other were wet with sweat. At this moment, a sudden gust of wind blew through the hall and blew the fire door in front of them, detonating their tense sanity to the limit. Looking at the closed passageway in front of them, they rushed down the stairs almost frantically, through the gloomy clothing stores—the fluttering clothes were like dancing ghosts—until a faint glimmer of light came into view.

"Whew...... Whoosh...... Over there, there seemed to be a bright light, and I remember it was the central patio. ”

He stopped his frantic pace and gasped as he spoke, looking around at his surroundings. They were located on a main road, flanked by rows of shops, all empty and invisible.

"Whew...... Okay, whoop...... Then let's go. ”

As one side approached its destination, the sound of a commotion in the crowd reached his ears as if it were nothing. He was even more convinced that he had found those who had left where they had been. But far beyond his expectations, when they reached the central patio, the emergency lights were shining on a group of delirious, or rather walking dead.

Before he could think about it, the smartwatch on his left wrist inexplicably stopped working. In the darkness, he could clearly see a sphere about ten centimeters in diameter suspended in the central patio, and countless magical worlds appeared in this underground square in some kind of projection-like fashion.

"That's, that's ......"

Immediately afterward, an unbearable stench poured down from the heights, causing the shivering party to feel suffocated and gagged, and almost collapsed to the ground. At the same time, the air began to tremble, as if huge wings were flapping. In the darkness without light, he could not clearly see who was responsible for these phenomena, but in the dim vision he could faintly see something larger and darker stretching out—something that seemed to be an invisible cloud.

"Ahh

With a high-pitched scream, dazzling electric light burst out from the girl's body. The darkness in sight was dispelled in an instant, but there was no joy in the light of the passage - under the blazing light, there was a pair of huge blurred black wings, and under the shadow of the wings were terrifying, three-petaled, burning eyes...... Everything in the visual organs seems to be distorted, the olfactory organs smell a terrible stench, and the auditory organs faintly hear a terrible "babbling...... Engay ...... Iga ......", a scream emitted by a non-human creature.

The unidentified terrifying being seemed to be terrified of the light, its large, vague form trembling and struggling to retreat before disappearing into the abyssal darkness projected from within the sphere.

Finally...... Is it over?

He suddenly felt his feet loosen, and his legs collapsed to the ground limply. The long-distance run had already made his muscles sore, and at this time, the breath of lifting was gone, and he could no longer suppress the feeling of exhaustion.

"So...... What was that thing just now?" After a long time, a low voice that had just entered the voice change period sounded in his ears, and he turned his head to see that the other party was a boy with messy short hair, who looked two or three years older than him, "I finally came to the business district, but I encountered this kind of thing, I am really unlucky!"

"I don't know. ”

One party said that he hurriedly got up and walked a few steps to the side, deliberately keeping a certain distance from the other party. The people around him, young and old, were delirious, and the only person who remained awake in such a situation, even if he appeared to be no more than a middle school student, was still a cause for alarm.

"Well, that strange thing seems to be gone. "The lighting system shows no signs of recovery, and the smartwatch and other electronic devices can't be turned on, and the only light source is the electric light from Mikoto Misaka's fingertips," whew...... Well, it doesn't seem that scary. By the way, who is this?"

"My name is Shang Tiao Danma. Are you an advanced electromagnet capable person? I didn't expect to be so young. The boy who claimed to be a hemp boy scratched his messy hair, "Looks like I arrived a little earlier than you...... Besides, what the hell is going on?"

"You don't seem to be that old, do you?" the girl was slightly upset when she spoke, and then patted Ichiban's shoulder, "My name is Mikoto Misaka, and this strange guy with white hair and red eyes is called Ichibantong." ”

"Is that really the right name? Forget it, let's not mention this for now, I think we should hurry outside and inform the security guards and the nearby hospital. He said, gesturing to the unconscious crowd around him, "I always feel that their state doesn't look right, and it doesn't look like they've been made like that imaginary monster......

Before the words of the party fell, he saw Mikoto Misaka beside him fall softly. Startled, he didn't have time to make a sound when he felt his throat be grasped by a pair of wide, rough palms from behind.

"Hmm...... Hmmm......"

He desperately commanded his muscles, trying to break free with kicks, elbows, or some other means. But all the nerve impulses coming from the brain are like stones sinking into the sea, drowning in the boundless cold ocean. The nightmare that had once been in Triyan seemed to manifest again, abominatingly destroying his tense nerves, and imprinting an unimaginable fear into his mind, before shattering and annihilating the fragile structure once and for all.

"Stop! What are you doing!"

In a trance, he vaguely heard the angry shouts of Shangjo Danma, and then he felt his neck loosen, and the whole person fell heavily to the ground. The only light source was lost due to the emitter's faintness, but he still felt some kind of black cloud dispersed and expelled, and his limbs seemed to show signs of regaining mobility.

The fingers were hooked, and the wrists began to feel sensation...... Something had to be done, and we couldn't sit idly by.

Just as one side was trying to stand up, the upper body was hit hard. A middle school student named Kamijo Danma was brutally thrown on top of him, his leg seemingly kicked by someone passing by, and his ears rang with some kind of strange syllable insccipherable voice—an obscure and mysterious language unlike any human language he had ever been exposed to, and perhaps not a communication tool designed for humans at all.

No, now is not the time to think about such inconsequential things. The identity and motives of the other party cannot be determined, mysterious rituals, strange creatures that resemble myths, and unknown means of making people unconscious, these magical things do not look like the creations of cutting-edge science and technology, and the communication equipment to communicate with the outside world cannot be used, but it is difficult for the three of them to fight back at this stage.

"Is prayer just a consolation? I think the Crucifixion is something like that, but you can call the Demon King's real name when necessary!

A joking conversation popped into his mind. The person who said this was a researcher sister with long pink hair and a strange ring-shaped double ponytail, named Nanamiya Tomoin. Maybe it's some kind of emergency key to activate the hidden channel of the smartwatch that the institute has issued to him - such as quantum communication or something?

With this thought in mind, Fang Tong whispered with the only remaining strength:

Sophia Lynn S.P. Saturne VII. ”

After saying this, he turned his head and glanced at his wrist. Nothing happened.

Sure enough, is this just a joke for me? Yes, how can such a miraculous thing happen just because of my childish thoughts?

Just as one side of the passage gave up on its struggle, a warm golden glow illuminated the central atrium as quickly and unobtrusively as a spring flower. What caught my eye was a back figure wearing a black coat with long pink hair scattered, and black gas on the surface of a pair of bat wings tumbling and surging.

"I'm [Magic Demon King Girl] Sophia Lin · SP Saturne VII, the second title is [Master of the Seven Elements of Magic], remember!"
