The cold mechanical sound forcefully squeezed into different dreams.

——Dear players, welcome to another dimension.

——The novice dungeon is about to open, please get ready and play actively.

The dark eyelids suddenly saw light.

Click, click.

The very regular sound became clearer and clearer from far to near.

The hand that had been holding the small schoolbag with yellow flowers and white background was tightly clenched, and the slender five fingers stretched out a strong arc.

The thick eyelashes trembled, and Jiang Yao slowly opened his eyes.

A small table with a weight of 25 kilograms and the passenger guide on the table came into view together. The repeated scenery passed by at a high speed outside the window. The hard seat under the body and the luggage rack above the head silently showed the new environment. identity.

a train.

train? !

Looking around, the densely packed seats in the carriage were all empty, and she was the only passenger.

Outside the carriages in this section, "numerous" carriages extend out, with no end in sight.

What is this place?

Subconsciously, she took out her phone and glanced at it. When she saw the signal bar in the upper right corner of the screen that had completely disappeared, a piece of information popped up from the corner of her memory, giving the answer.

Since five years ago, a literal black hole has appeared in the sky over Huaguo on the 15th of every month.

It randomly appears in various cities, and it will take away anywhere from ninety to one hundred citizens each time, without causing any loss other than that.

Such bizarre events naturally aroused the panic of the people, and for a time the doomsday theory was rampant, and people were panicked.

The state attaches great importance to the establishment of a special investigation team, which has expended huge manpower and material resources, but unfortunately until now, nothing has been found.

Over time, this man-eating "black hole" has a nickname - the third evil.

Natural disasters and man-made disasters are the third harm, the first two are life and death, and the third harm is not seeing the dead body.

Once swallowed by a black hole, there is no way back.

At least the people who have been swallowed so far have not been able to recreate society.

No, it's not called the third evil anymore, it's a different dimension... There are no novice dungeons, games, and players.

Jiang Yao remembered the inappropriate electronic sound that inexplicably appeared in the dream before waking up, and one of the conjectures that had been widely discussed before entering the different dimension was finally confirmed.

——The disappeared people are tools chosen by unknown forces and will be used in the new space.

"Ding ding ding ding~~"

Suddenly a burst of cheerful music sounded, and Jiang Yao shivered, only to hear the sweet female voice being amplified by the loudspeaker and resounding throughout the car.

"Dear passengers, welcome to take this train."

"This train is 1,729 kilometers one-way, and travels round-trip at a speed of 196 kilometers per hour." "

Every time you stop at a station for two minutes, a door will be opened randomly at each stop." Passengers getting off, please prepare in advance."

Click.

The broadcast ends.

Before she could recover, the weird timer in front of the first row of seats in the car suddenly lit up.

The scarlet number jumps from zero, indicating that the game has officially started!

The carriage returned to silence, and a needle could be heard.

Jiang Yao shook his head slowly holding his schoolbag.

No, she doesn't want to play any novice dungeons, she wants to go home.

Pulling down the phone's address book, she dialed from 661 to 669, and from 110 to 119, over and over again.

"Hello, the number you dialed is not in the service area..."

"Hello, the number you dialed..."

"Hello..."

At the end of the call, the futility she knew made her eyes blush and powerless Slumped on a chair.

The screen turned off, revealing a young and immature face.

Staring dazedly at his frightened and ugly face reflected in the reflected light, Jiang Yao's nose soured, and the next second he turned the phone over, lay down on the small table, and buried his face in his arms.

His chest rose and fell slightly with his breath.

The fingers clasped on the phone kept curling inward until the knuckles turned white and blue.

No, you can't be so useless.

Jiang Yao wiped away tears, and turned the phone over when he sat up.

She pursed her lips, her chin arched resolutely, and she tapped the screen vigorously with her thin fingers, quickly summarizing the known conditions on the sticky note.

——April 15, 2030, the temperature is 18~25c

——1. Different dimension, novice dungeon.

——2. Train, Passenger Guide.

——3. Passengers, open the door at random, 1729km, 196km/h, 2min.

When she was done, she picked up the passenger guide.

This is an ordinary four-fold page, the length and width of the palm.

The outermost page is printed with an ordinary locomotive. After opening, the first page and the second page introduce a few words about the manufacturer of this train, and the third and fourth pages are the internal structure and settings of the train. Doors, fire extinguishers, timers, seats, window-breaking hammers, the reverse side pinches the head and tail, horizontally the floor plan of the train.

Jiang Yao read it twice and put it in his schoolbag.

Then put your schoolbag on your back and stand up, looking at the same empty carriages in the front, back and back.

According to the third point and the law of cannibalism in different dimensions, there should be other people in this car.

So go forward or go backward...

The strokes in the front are nine, and the strokes in the back are six, which happens to be one odd and one even, which is in line with the way of tossing a coin.

She randomly divided two numbers and tossed a "coin" in her mind.

1000/73=13698630136986301...

Eight numbers cycle, eight is an even number, and then go on.

Jiang Yao turned to the rear, looked at the slightly shaking carriage, took a deep breath, and bravely took the first step.

"Fuck you!"

A young man with blond hair and lip studs grabbed the collar of a middle-aged man in a leather jacket, raised his knee high and bumped into the middle-aged man's abdomen, "You fucking run, now Well, if you die, you will die, and you will bring bad luck to the brothers!" The

middle-aged man was injured in the abdomen, vomited a puddle of acid water on the young man, and got punched and kicked again.

The four flower-armed youths behind the man with the lip nails all showed disgusted expressions. If the space in the carriage was not too narrow, they would have boarded together a long time ago and let out such a bad breath!

"Don't, don't hit..." The middle-aged man cried bitterly, "Brother Guang, please forgive me... I will pay back the money... I will never dare again..." The

man with lips nails laughed angrily , dragged him up from the ground, and gave another loud slap, "Forgive you? I want to forgive you, but you, seeing me run once and for all, have reached here, you fucking still run! I If I don't knock the shit out of you, I'll—"

The rude swearing stopped abruptly, and the man with the lip nail fixed his eyes on the joint of the front carriage.

The rest of the people were puzzled and followed his gaze.

A sixteen or seventeen-year-old girl appeared there at some unknown time. She was wearing a pink hooded sweater, her hands were tightly clutching the straps of her schoolbag, her expression was a little nervous, and her fair and beautiful face was tense. .

The ball head, which is very popular among little girls, is a little loose, and a few strands of hair hang down randomly, making the person even smaller and pitiful.

No matter how fierce the man with the lip nails was, he had no experience in beating and killing in front of a little girl, so he was stunned for a moment.

Jiang Yao was very flustered, and even more flustered when he was seen by these young people who didn't have any serious career at first glance.

When she was in the front, she was too happy to see people, and she walked too fast. When she found out that these people were beating people, it was too late, and she was caught by the man with lip nails just as she was about to leave.

She was afraid that she would be beaten like that uncle when she left now, so she had to bite the bullet and say hello: "Brother...Hello, brothers, and that uncle is also...okay." Social youth: "..."

Lip

nails It took a long time for the man to let out a fart, and signaled his companion to grab the man in the jacket so that he wouldn't let him run away.

He took a few steps forward and asked, "Little sister, are you alone?" Why does this sound so hooligan? !

Jiang Yao could tell that he was not malicious, so he nodded obediently.

The man with a lip nail nodded to hide his embarrassment, and glanced behind her, "I don't know what's going on in this car, it's dangerous for you to wander around by yourself, why don't you follow us first..." After finishing speaking, he was afraid that Jiang

Yao Misunderstood, quickly added: "Don't worry, we don't bully children or women, we just feel that you are not safe by yourself!"

Seeing that his face was blushing, Jiang Yao suddenly felt no longer afraid. As for the brutal episode where they beat someone just now...it really makes people angry if they don't pay back the money they owe.

Alone, she couldn't refuse such an invitation at all, and nodded quickly.

"Thank you brother."

The man with the lip nails coughed, "Thanks are welcome, but we don't know what to do now, except for a guidebook with no flower heads, so we can only take one step at a time It's gone."

When it comes to this, everyone gets annoyed, "It's really bad luck for eight lifetimes, and I met this scumbag!" "

If my mother can't contact me, she will definitely cry to my grandpa again and say that I was stabbed indiscriminately." Hacked to death in which stinky ditch."

"Don't worry about how your mother cried, the third evil has no way out, let's cry for ourselves first."

Everyone glanced at each other and sighed in unison.

Why.

Jiang Yao hesitated for a while, then slowly raised a hand.

Man with nails on his lips: "...Sister, we don't need to raise our hands to speak here, you can say whatever you want."

With this cooperative attitude, Jiang Yao relaxed a little, and took out a notebook for drafts from his schoolbag , and took out a pen.

"Actually, there are clues." She wrote down 1729 and 196 respectively on the paper. "The radio said that 1729 is the mileage and 196 is the speed. Then we can get the arrival time." Her pen paused for a

second , and then smoothly write out a "31757s".

"The driving time takes 8 hours, 49 minutes, and 17 seconds. For the convenience of matching with the timer, it is recorded as 31,757 seconds here." The

young people in society looked up at the timer in front of them.

The current time is 492 seconds.

After everyone finished watching, they all turned back to stare at Jiang Yao.

"AlsoThat is to say, when the timer jumps to 31757, the door is opened. "Jiang Yao circled a beautiful circle on the number, drew a straight line beside it, took the midpoint, and continued: "The broadcast also said that the door is opened randomly, and it only opens for two minutes, so in order to let this It is meaningful to open the door. This train must have an end, and the length should not be particularly long. I guess the longest is about 1,000 meters. "

Although we don't know what else will happen, we can find the midpoint of the train first, so that we can get off later." "

Jiang Yao looked up after finishing speaking, but met five, oh no, six ignorant faces.

"Well..." Jiang Yao loosened a strand of hair again, and began to explain: "Because the door can be opened at will. , and we only have two minutes to get out of the car, so if we are far away from the door when it opens, it will be too late to run over, and we will not be able to get out of the car. But if we are in the midway compartment of the train, we can put aside the luck factor and minimize the door opening distance and the risk of getting off the train. "

Oh——"

Now everyone understood, but there were other questions.

"How do you remember the distance and speed so clearly? I didn't pay attention to it, and I completely forgot it." "

... Ah me too, I didn't remember this. " "

Looking at everyone's curious faces, Jiang Yao explained seriously: "Although every number is strictly unique, there are always some that are relatively special and easy to remember, such as these two numbers. 1729 is the origin of Ramanujan's taxi number, and 196 may be the smallest Lychrell number. As soon as the broadcast was played, these two terms were automatically substituted in my mind, and I remembered it clearly. "

The young people in society were dumbfounded.

Seeing everyone's ignorant faces again, Jiang Yao hurriedly organized his words and tried to explain: "Ramanujan's taxi number is the cube of two numbers that can be written in two ways..." "Wait, wait!"

Lip Nail Nan regained his composure and hurriedly interrupted, "There is no need to explain this!"

Jiang Yao opened his mouth, oh, and then closed his mouth.

Everyone slowed down for a while before they came back.

"Obviously I know every word, but I don't understand a word. I wonder if I have graduated from high school..." "Graduated from

technical secondary school, I have the nerve to say it in front of my sister!" , let people go away, looking at Jiang Yao's eyes became more and more affectionate, "Sister, from now on, you are my own sister, and I will appoint you as the military advisor of our team from now on. We will listen to you if you say what to do." !"

Jiang Yao has received many praises and praises since he was a child, but this is the first time he has seen someone so straightforward and rude.

With red ears, she whispered: "I will do my best."

The youth in society have strong executive ability, and they do what they say, and immediately started to number the carriages.

There is a marker pen for highlighting in Jiang Yao's schoolbag, which happens to be used for marking.

She thought for a while, and gave her first order: "There should be people in the other carriages, let's continue going backwards." "

Okay!"

A group of people threw the "coin" towards Jiang Yao Go, and sure enough, I met a lot of people again.

There are young couples, there are families of four, and small groups like them get together.

Because most people would be a little jealous of people with flowery arms and fierce spirits, especially the man with the lip nails dragged a half-dead here, so other teams are gathering, but they are the only ones that stick to it.

Of course, no one cares.

"Finally we've come to the end! It's gone so fast...well, more than four hundred seconds, seven minutes!"

Li Guang, the man with lip nails, let out a breath, and wrote a big "1" next to the timer with a marker.

Jiang Yao roughly calculated the speed and distance, and said angrily: "We should have gone forward, and the repeated section will not be so long." It took

30 carriages to find the end, according to her estimated train length Forget it, the other end should be about ten knots.

Li Guang comforted her: "It's okay, why don't we just take a few more steps, and we still have plenty of time, so don't worry."

Jiang Yao was still sullen and angry at himself, and it took a while for him to calm down, and took out the passenger guidebook again. look.

Li Guang and the others didn't bother her, and the man with the jacket wandered around the last few carriages, looking here and there, including the bathroom and under the seats.

Unfortunately, nothing was found.

Li Guang smoked a cigarette and exhaled: "Hey, don't you think it's too long, almost nine hours, and let us wait in the car for the door to open?" Someone answered: "Who knows,

this ghost place It's unreasonable, who the hell builds so many carriages in one train? Don't be afraid of slipping your waist when turning!"

This is an interesting remark, and the group of people laughed.

Li Guang shook the cigarette ash and sighed, "I just hope that nothing will happen again..."

Before he finished speaking.

"Di-di-di-"

The ear-piercing sound of the whistle pierced the eardrums unexpectedly, and the red light that came from nowhere instantly filled the entire train.

The blue-gray seats, the scenery outside the window, and the people in the compartment were all dyed red!

After a long distance, the sharp screams pierced into the depths of Jiang Yao's cochlea like needles.

"Monster! Monster!"

"Help——"
