23:44.

At the empty light rail station, Gu Shen looked down at his watch while running.

Can you still catch the last bus? He was a little worried, but a low chirping sounded immediately from afar.

"Boom--"

In the dark and dark tunnel, thousands of brilliant arcs of light burst out in an instant. The last light rail train slowly slowed down and stopped steadily in front of Gu Shen.

Seeing the train, Gu Shen breathed a sigh of relief, then frowned again and held his breath.

The door of the compartment opened and a smell of rust came to my face.

He took two steps back and looked at the train. The carriage was old and the appearance was mottled and rusty. He wrote three neat numbers next to the window with white paint:

Zero or zero.

"If I remember correctly, Otoshi City...hasn't this kind of train been eliminated long ago?"

"Didi--"

Before I could think too much, I wiped the last moment when the car door closed, Gu Shenmao ejected his waist and rushed into the car without any danger.

Holding the handrail, breathing a sigh of relief.

Yu Guang glanced inadvertently.

"Oh huh..."

Gu Shen's heartbeat slowed down a beat.

On weekdays, this light rail is sent to remote suburbs, and the last bus is often not taken by others, only by themselves, but today...

There was also a girl in the carriage.

Gu Shen felt that his heart was about to melt. The girl was sitting opposite him, less than 30 cm apart, with almond eyes and peach cheeks and long hair. She was wearing a thin, almost transparent pure white lace dress, exposed her fair shoulders and large areas of snow-like skin.

The thin skirt was very white.

But the girl was even whiter, so white that she was a little dazzling.

The girl was not wearing shoes, and she stepped lightly on tiptoe on the ground of the carriage... On her knees was a thick book with half spread out, quietly reading the thick book.

This girl is too perfect, with an unspeakable unique temperament, unlike a person who is real in the real world. Looking at her, Gu Shen felt like he saw a beam of light.

Quiet, soft, holy, and ethereal.

During the break between turning the page, the girl raised her head.

The two of them looked at each other, and Gu Shen quickly moved his eyes away, rubbed his hands and angrily, hurriedly covering up his loss of composure.

He suspected that he was dreaming.

How could there be such a beautiful girl in this world?

Also... she doesn't feel cold when she wears so little?

I really want to lend her my coat to wear.

...

...

【The second person... got in the car.】

The girl looked up, surprised flashed in her eyes, then closed the book and looked at the boy boarding the bus carefully.

Although the boy is now huddling in the corner of the train, rubbing his hands and giggling on his own, he doesn't know what "get on the train" means.

But she knew very well that it could not be a coincidence.

"Woo--"

The light rail is slowly launched, and the arcs splash back and forth to wash the tunnel walls.

Although this train is old, it travels extremely smoothly.

The sound of electric arc ejection outside the window, after the glass was penetrated, there was only a rustling sound like rain.

Neither of the two spoke, just kept it quiet. If no one spoke, the light rail would pass through the long tunnel and drive silently for about twenty minutes to reach the terminal.

But this calmness did not last long and was soon broken by the girl's crisp voice.

"A very important question: Is there a real π between 3 and 4...?"

Gu Shen thought he was auditory hallucinating.

Are you talking to yourself?

He turned his head in surprise, looked around, and saw the empty inside of the carriage, and met the girl's gaze that was staring at him seriously. Gu Shen pointed at him, and the girl nodded seriously.

He smiled awkwardly, and the other party was really talking to him.

"Is there a real π between 3 and 4...?"

What is this problem?

The answer is of course there.

But at this time, Gu Shen hesitated for a moment and did not answer directly.

The reason is also very simple.

Because the girl looked directly into her clear pupils, she reflected an extremely serious wave of light, and this look made Gu Shen believe... This seemingly simple question is not that simple.

The girl stretched out a hand and pointed behind Gu Shen.

Gu Shen turned around.

There was a mottled mural in the interior of this old car at some point... It was vaguely seen that it was an old scale with a long scale and nowhere to spread to it, but what can be clearly seen at this moment are the two numbers 3 and 4 marked with bold marks on it.

"If you touch this ruler..."

The girl stretched out a hand and touched the ruler from the air. Her voice became lighter, like a gust of wind swept across the carriage, with a faint sadness.

"Can you touch π?"

Gu Shen was stunned.

He suddenly understood the true meaning of this question, a number that is infinitely uncirculated, and a number that only exists in theory.

The accuracy of this number is infinite.

The accuracy on the ruler is limited.

Even if this ruler is enlarged billions of times, it will never have a point, which belongs to the "π" with infinite accuracy.

"Gu Shen...what is your answer?"

Gu Shen was a little confused. She knew her name?

The girl's hand stretched out slowly spread out, and there were silver cross patterns flowing in her palm, emitting glow.

The moment he saw the cross glow, Gu Shen felt familiar and warm, as if he had returned to an old dream. He couldn't help but make the same move. The boy stretched out his hand and wanted to connect with the girl's five fingers.

"Puff."

Seeing this action, the girl smiled.

No touch as imagined.

The girl in the pure white gauze skirt stopped and stepped back little by little, retreating to the end of Gu Shen's sight. The girl's smile disappeared bit by bit, and in the end she was only solemn and serious.

"Gu Shen..."

“…Live.”

The wind in the car suddenly dissipated.

"Rumbling!"

Light rail exits the tunnel—

The light source shrouded above Gu Shen's head instantly shattered.

If there is really a daydream in this world, then what Gu Shen just experienced is the most wonderful daydream in his eighteen years of life, although this daydream happened at night.

But the light rail exits the tunnel and the dream is shattered.

He suddenly realized... everything had changed. The moment the mottled train drove out of the tunnel, it seemed to be washed and washed by invisible force.

The light rail began to tremble, and the entire carriage was in violent shock, like a curved steel snake body, bumping and undulating, and the arcs splashing outside the window were all extinguished at this moment.

The wheel hubs collided with the rails, and the harsh friction sound that shattered the dream.

Gu Shen looked at the scene in front of him in a creepy state.

The light in the entire carriage dimmed and was still empty.

But the girl's seat was replaced by a tall woman in black dress.

She wore a topper that was wide enough to cover her entire face, held a stack of yellowed and old newspapers in both hands, reading in the fragmented lights, and even sitting, she was almost as good as Gu Shen.

If you stand up... I'm afraid it's more than two meters long, right?
