June 14, early in the morning.

Sure enough, the nightmare woke up all the members of the expedition team on time. When Xiao Ye turned over and sat up with the head of the chicken nest, and saw that Xiao Jie and Xiao Ling were also full of hair and sad faces, they felt a little funny at an inopportune time. Instead, Ghost Stone and Yongkira, who were on guard, were sleeping soundly, apparently unaware of anything unusual and unable to prevent the nightmare from happening.

Fortunately, the contagious dream did not affect Xiaotian and Xinghai, and it also responded to the previous speculation about the "nightmare trigger condition". After lightly completing a series of actions of washing and dressing, the team met in the hall - even Kiritha, who claimed to sleep until noon without stress, could wake up on time, which showed that the power of the masked monster in the dream was indeed extraordinary.

Unfortunately, the side effects of the Nightmare Alarm Clock were so great that all four of them now felt like their heads were going to crack.

Xiao Ling even began to stare at the ground in a daze, for fear that her brains would drip down and stain the floor of the hall.

Even to stop the nightmare, now they must find out the truth as soon as possible - if they continue like this, they will become evil spirits themselves.

At 6:25, the four members of the expedition team arrived on time at the terminal of the Hibiya Line, H18 Minamisenju.

"Wow, there's no one. Xiao Ling exclaimed expectantly. The subway in Mihara City has always been crowded, and it is rare to see a scene of silence and no one, and it is really a bit of an adventurous atmosphere for a while.

The golden retriever girl seemed to want to see more of the rare and quiet subway station, but she didn't turn a few times before she leaned against the wall, "No, my head is so dizzy......"

Xiaojie laughed twice without conscience, and took out his mobile phone, "But such a subway station is really rare, I'll take pictures...... Huh?"

"What's wrong?" asked Sayo.

"My phone has no signal. Jay pressed the camera icon on the screen in confusion, "And it seems to be dead......?"

Kiritha was stunned and checked his phone, "Mine has no signal...... It's weird. ”

The subway in Mihara City has been set up with seamless mobile communication coverage along the way, and the signal should be very smooth. At least when they came to Nansenju Station yesterday, their mobile phones were working fine.

"I said......" Xiao Ling, who was finally able to stop supporting the wall, walked over in a flutter, "Did you hear any sounds?"

All four men pricked up their ears at the same time and held their breath.

The sound of the wheels clashing against the track gradually approached, and even the air became agitated. It was a black-and-white train - its body was very worn, rust crawling like spider's webs, and the glass that should have been transparent was covered in dust. As it slowly stopped beside the platform, a cold wind swept up, revealing an old, decaying smell.

The four of them did not make a sound, but made eye contact with each other's astonishment.

The subway on the Hibiya Line was not in such a state of disrepair, but now it was clear that it was an antique train that looked like it was fifty years ago.

"Is there really a train we haven't seen before?" Xiao Ling's eyes widened and she whispered in a breathy voice.

The dilapidated black-and-white train stood still next to the platform, and the doors opened with a creaking sound.

The expedition team hesitated for only a second, and then stepped into the strange train - no freelance trainer could stop at such a time.

There was no voice announcement in the car, perhaps because the equipment had been damaged for a long time, and only a rustling noise could be heard from the horn. The silent black-and-white train closed its doors and drove the young four passengers in an unknown direction.

Sure enough, there was no one. Xiaojie gave full play to his eyesight advantages, and after a careful look, he came to a conclusion. Considering that Kiriha, who didn't know about Xiao Ya's abilities, was present, Xiao Jie didn't speak directly, but turned his inquiring gaze to Xiao Ye - what is the detection result of the power of the waveguide?

The other party hesitated, did not respond to Xiaojie's gaze, but stared at his partners vigorously, making him suspect for a moment that his posture of passing his eyes was not right.

Of course, Xiao Ye understood what Xiao Jie meant, but she didn't know how to express what she was feeling now. The enveloping range of the waveguide's power has been stretched to the limit, but all that can be detected is a haze, whether it is the train, the track, or even the three living people around them, it seems to be engulfed, and they do not appear in perception at all. For the waveguide messenger, it's as strange as hearing someone talking around you, but reaching out and not touching anything. And perhaps because of the nightmare, she felt her head become more and more dizzy, and even the waveguide detection became swaying, and a sticky sense of uneasiness suddenly crept up on Night's back.

Before Saya could decide whether to explain the truth or hide it for the time being, a shrill phone rang suddenly from the carriage. Everyone was frightened and hurriedly looked around for the source of the ringtone.

It's a very old-fashioned ringtone, and in an age when even the default ringtone on smartphones is pleasant music, the only way to hear it is to watch a TV series set in the last century. The members of the expedition team, all of whom were deaf and discerning, listened intently for a moment and looked at each other - the strange sound of the bell was clearly coming from all directions, echoing violently in the small compartment space, as if it was about to overturn the old body.

"Let's go ahead and see. Sensing that this would only lead to panic, Kiritha immediately said, "Even if there are no passengers, we can ask the driver about the origin of this car." ”

"Good. Xiao Ling knew that there was no point in continuing to be baptized by the ugly ringtone, so she resisted the urge to lift the ground up to find the sound phone, and nodded.

As the group marched towards the front of the carriage, the bell gradually faded and became vague. I don't know if the noisy volume stimulates the eardrum too much, Xiaoling always feels that the sound is still ringing in her ears from time to time.

After walking silently for a while, Xiao Jie finally couldn't help but speak: "We should have walked through at least ten carriages, right?"

"It's eleven verses. Kiriha pondered, "It stands to reason that you should already be able to see the front of the car, but ......"

Kiripa didn't need to complete the second half of the sentence, and everyone knew what he wanted to say - there was still a cookie-cutter carriage in front of him, and there was no end in sight.

"And the subway is running for too long, and the two stations shouldn't be so far apart. Xiao Ye added softly.

As soon as the words fell, the train suddenly braked, and the four unsuspecting people staggered as the carriage shook. The old carriage creaked and groaned, and it was thought that it was about to fall apart.

When the train stopped, everyone stood up rubbing their heads and finding that the door had been quietly opened. The platform outside the carriage was lit up with a dazzling white light, as if everything was normal.

"Anyway, let's go out and have a look, shall we?" said Sayra, taking the lead towards the door. As soon as she walked to the door, she was suddenly grabbed by Kiriha.

"Little Night...... Look at your feet. ”

Xiao Ye lowered her head, and her body immediately stiffened.

It wasn't the ground of a platform, it was a bottomless abyss of darkness.

Before the purple-haired girl could return to her safe position, the entire carriage suddenly shook violently. The supposedly solid ground cracked inch by inch, the wheels and rails shattered like glass, and the four young riders fell into the cold-cold cliff.

Saya's hand instinctively wanted to touch the Poké Ball on his waist and release the flying Charizard. However, her body became extremely stiff, and even with the absolute calculus turned on, she could not move even a finger.

Instinctively trembling from the free fall, the purple-haired girl barely rolled her eyes, catching the figures of her companions below and the terrifying creature.

The giant masked monster grinned, the half-crying and half-smiling pattern constantly twisting, unleashing boundless malice. The black hole inlaid with sharp teeth rapidly expanded on the mask, and the fangs made an explosion when they clenched.

The light of the fire tore apart the darkness. Xiao Ye watched as the heat engulfed her friend's figure, and then she was completely enveloped in the scorching air.

"Boom-"

The pain of hitting the ground from the skull made Xiao Ye suddenly wake up, and she immediately instinctively rolled over and made a defensive posture.

And then...... She saw her three friends lying on the ground in various magical positions, and Xiaojie even stuffed his head under his stomach. The cleaning workers passing by were full of astonishment, probably thinking that they had encountered a group of mentally ill people.

"Pain, pain, pain......" Xiaojie tried to adjust his posture to the appearance of a normal human, and looked around with palpitations, "What's going on?"

"We did fall and be eaten by the masked monster...... Kiriba hurriedly looked around, finally recovering from the horror of life and death, and found that he had returned to the terminal of the Hibiya Line, next to the stop sign of H18 Minamisenju Station.

Xiao Ye, who opened the waveguide detection in the moment of wakefulness, finally felt the familiar information circulating, and couldn't help but breathe a sigh of relief—this time it was not a fog that he perceived, but the platform and three living people.

Oh, it's four, and the janitor in the corner who already wants to call the police.

"Ah, the clothes are not burned, and they are not disfigured...... " Xiao Jie muttered quietly, and touched his head uncomfortably to see if it was still intact, "Why did we suddenly come back here......? Finish...... Uh, Xiaoling, are you alright?"

Before the words fell, Xiao Jie only felt a yellow shadow rushing towards him, and before he could see his sister's teary expression, he was thrown down with two other dazed friends, and the back of his head kissed the ground again.

"I ...... I thought you were all dead, woo wow wow wow wow-"

Finally calmed down the blonde girl who was crying miserably, and the four of them hurriedly left the subway station - now that there were more people in the subway station, it would be too conspicuous to stay inside.

"So, what the hell is going on?" Xiao Jie grabbed his hedgehog head even more, "We took a train that shouldn't exist to H19 station, where we met a masked monster, the monster ate us, detonated a few bombs in its stomach to show us, and then spit us back into H18??"

Without waiting for his partner to answer, the golden retriever boy shook his head first, "No, it sounds like a psychopath giving a speech......"

"That. Xiao Ye raised her hand, "I have a discovery, although I don't know if it has anything to do with what just happened......"

She pulled out the card that had been in her pocket, "The color of the pattern on this card has faded. ”

The three heads immediately leaned over and stared at the already gray Crying Mask.

"Really. Kiritha immediately took out his own stamp and exclaimed briefly, "Ah, mine is ...... too"

The traces left by the black ink are blurred, making the stamps look even older.

"What's going on...... "Xiao Jie looked at the two pieces of paper in confusion, and when he inadvertently looked up, it suddenly turned into a stone pillar.

Xiao Ye and Xiao Ling followed Xiao Jie's gaze inexplicably—they were immediately stunned, and Xiao Ling's expression was even more terrifying as if she had seen a ghost in broad daylight.

Kiriha was wondering why the three of them suddenly began to stare at her, Xiao Ling raised her finger tremblingly, and her voice changed tone.

"Masks, masks...... Kiriha, the mask is on your face!!"

====================

Small Theatre:

Before the words fell, Xiao Jie only felt a yellow shadow rushing towards him, and before he could see his sister's teary expression, he was thrown down with two other dazed friends, and the back of his head kissed the ground again.

Xiaoling: (crying) I ...... I thought you were all dead, woo wow whoa-

Xiaojie: (also crying) I wasn't bitten to death by a monster, but I'm about to die of a concussion!
