On a summer afternoon, the sun is so hot that even the sound of cicadas disappears.

At the Third Military Academy on the outskirts of Shanghai-Hangzhou United City, Lu An slept soundly on the sofa in his dormitory.

It was two o'clock in the afternoon, which was the hottest time of the afternoon, but the bedroom was very breezy and comfortable.

Suddenly, there was a slight sound of the door opening.

The door popped open, revealing a sweaty man standing outside him, his neat military uniform half-soaked.

Seeing Lu An sleeping soundly on the sofa, the visitor smiled and walked in cautiously with his luggage.

Lu An fell asleep wrapped in a blanket, and in front of the sofa, there were a few pieces of paper scattered on the ground.

My roommate still has such a strange habit!

Loved sleeping in the living room, loved sleeping on the couch, loved using paper so retro.

In today's era of information, everyone relies on the "intelligent brain", and all the information interaction in the world can be realized through this so-called "artificial organ" in history.

And "paper", an information carrier that has long been eliminated, has become so rare that it is rare to see.

Therefore, Lu An's habits are extremely weird.

However, having lived in the same dormitory for four years, as Lu An's roommate, Lin Yongping has long been surprised.

He came to the sofa and squatted down gently, collected the scattered papers for Lu An, and carefully placed them on the table.

smiled at the sleeping Lu An, turned around and prepared to go back to his room.

"Hey, Lin Dashao, are you back?"

On the sofa, Lu An rubbed his eyes and asked.

Lin Yongping sighed helplessly: "You are really sensitive enough, I don't want to wake you up." ”

"Well, it's okay, I'm just getting enough sleep. Heh-"

Lu An yawned, summer afternoons were always very lazy, and he couldn't wake up no matter how he slept.

He squinted and reclined on the sofa and asked, "It's a week before school starts, and you're back early." ”

"Well, some things have to come early. Moreover, there are a bunch of exams after the start of school, which are related to the distribution of internships in the army, so you must always come back in advance to prepare. ”

Lu An rolled up the blanket on his body, yawned, and sighed: "Lin Dashao, what else do you have to worry about?" You don't want to go wherever you want. But I, in case I don't graduate, I will be thrown into the asteroid belt to eat ashes, but, heh, ——, is too miserable. ”

Lin Yongping returned to his room, took off his soaked coat, and asked, "Are you sure you want to graduate early?" ”

"Yes, I've already told Senior Head Teacher Xie. Anyway, I'm so young, and I can't get an internship in the army, but she seems to be very reluctant. ”

Lu An muttered, complaining a little.

"I'm choking on the sun, so I'm going to wash first. You, if you graduate early, of course the head teacher is unwilling, but she has always wanted you to stay in school for further study. ”

Lu An was noncommittal, just looked down at his **** upper body, and said proudly: "Who made you dress so neatly?" Not to mention that there is not even a ghost in the school now, even if you, Young Master Lin, don't wear a uniform, who would dare to check if you can't do it? ”

It's a pity that the sound of water came from the bathroom, which overshadowed Lu An's voice and made him a little bored.

However, Lu An's brain received a text message.

"By the way, the school security has your package there. Also, it's winter on Mars, and it's normal for me to dress like this. ”

Lu An pouted, what a strange roommate.

In the bathroom, he never said a word, but used his brain to send text messages. If you can't shout, are you still afraid that your voice can't suppress the sound of water?

But it's winter on Mars?

I flipped through it on my brain, and sure enough, it was really winter in the seventh area of Mars, and it was estimated that the Kunlun Sea was frozen again.

Lu An yawned and stood up from the sofa, glanced at the neat programming map on the table, and felt a little strange in his heart.

Parcel? What package? Who will send a package to themselves?

The old man, grandma, and sister won't, the roommate is taking a shower in the bathroom opposite, and the only two friends went to Venus for a summer vacation, and they won't send any packages at this time.

For the rest, do you know anyone else?

Odd. Lu An was a little puzzled.

However, I can't manage this for the time being. It's time to go, and it's time to go.

Lu An looked at his brain, and on the holographic projection in front of him, a date marked in bright red.

August 25th.

It should still be the twenty-fourth over there in Zero, well, let's go.

Lu An shouted towards the bathroom, "Lin Dashao, I'll go out." ”

There was only the sound of water in the bathroom, and there was no echo in silence, as if no one was there.

Lu An shrugged, put on the uniform of the military academy, opened the door and went out, and just closed the door, another message popped up on Zhi's brain.

"Got it."

Coming out of the dormitory, it was the heat raging outside, and Lu An finally realized the feelings of his roommate just now.

When he walked through the long campus road under the scorching sun and arrived at the station outside the school gate, most of his clothes were soaked. However, after Lu An entered the dilapidated ground rail car, it was as cold as a winter day.

No way, it's like this for free things.

This semi-obsolete public transport facility is so dilapidated that it doesn't even have a smart thermostat, and the air conditioning turns on like winter in summer and the heating turns on like summer in winter.

Take this kind of public transportation that should have been eliminated a long time ago, and the scorching summer will be two days of ice and fire, and the cold winter will be two days of ice and ice.

But as long as he can save money, Lu An still gritted his teeth and endured it, and he got used to it after all, and he has been used to it all these years.

After finally getting out of the two heavens of ice and fire, Lu An came to the sea east of Shanghai-Hangzhou City, the busiest airport on the west coast of the entire Pacific Rim.

It's just that he doesn't want to cross the stars in a spaceship, but to take a speeding vacuum train under the airport from Shanghai-Hangzhou City in the thirteenth district to the zero area in the middle of the Pacific Ocean.

The ultra-fast vacuum train runs through the undersea vacuum tunnel that runs through the east and west of the Pacific Ocean, from Shanghai-Hangzhou City in District 13 through District 11 and District Zero, and ends on the west coast of District 4.

Of course, this kind of old passenger transportation, like "ice and fire", is a semi-obsolete facility.

After all, public passenger spacecraft that have been reaching any part of the globe in an hour have long been criticized and proposed to be abolished.

Fortunately, perhaps some giants in Area Zero are more nostalgic and have repeatedly rejected such proposals.

In this way, Lu An was very happy.

After all, these things are cheap and he is very short of money, otherwise he can only face the Pacific Ocean and sigh with joy.

After sleeping for three hours on the speeding vacuum train, Lu An was woken up by the violent and rough shaking. Wiping his saliva, he complained a little about such a primitive arrival reminder before he got off the train and left the station.

From Zone 13, which was on the afternoon of August 25, across the Pacific Ocean to Zone Zero, it was now past 11 o'clock in the evening in Area Zero, and of course, it was past 11 o'clock in the evening on August 24th.

Although it was midnight, the streets of District Zero were still crowded with people, and the flow of people commuting to and from work was crowded.

After all, Area Zero, as the "heart" of the human world today, works 24 hours a day.

Surrounded by the Pacific Ocean, even if the land is reclaimed, it is still a small area, and there are not enough residential areas for tens of millions of people, so there are many people coming from all over the world by public passenger spacecraft.

And coming out of the underground station of the submarine vacuum tunnel, Lu An, with his military academy uniform, squeezed into a passenger spaceship bound for the joint command, free of charge.

The Joint Command is located on the east side of United Peak, the core of Sector Zero, and is now the brain of all human armed forces. However, Lu An's destination was not the building of the Joint Command, but the Honorary Military Cemetery on the east side of the Joint Command.

Ten minutes later, the passenger spacecraft arrived at the Joint Command, and the crowd flowed out.

It is the summer of the Northern Hemisphere, located in the zero zone of the central tropical region of the Pacific Ocean, and August and September are the hottest seasons, and even the midnight sea breeze still can't dispel the sultry feeling.

After getting off the passenger spaceship, it was only ten minutes before Lu An was sweating profusely.

The Honorary Military Cemetery was renovated to commemorate the martyrs and heroes who died in the war ten years ago.

Lu An came to visit his father, every year, and this is the tenth year.

However, when he arrived at the gate of the cemetery, Lu An frowned.

The cemetery, which used to be free to enter and exit, has now set up a cordon at the door, and the slightest close is checked by the guards. Even though Lu An stepped forward to reveal his identity as a military cadet, he was still ordered to withdraw from the cordon.

"What the hell is going on?"

Lu An frowned and looked at the zero zone time displayed on the brain.

"Hello."

Not far away, a person walked out of the shadow under the tree, and suddenly opened his mouth to greet Lu An.

Lu An looked back and saw that the person was also wearing the uniform of a military cadet, and he had the accent of the fourth district. However, today's Brain Simultaneous Translation has been able to allow people in different languages to communicate in a basic way.

"Hello." Lu An took advantage of the bright afterglow of the lights on Union Peak to see the school emblem on that person's body that was different from his own.

"First Military Academy, Sean Leonard."

Lu An stretched out his hand and shook it, "Third Military Academy, Lu An." What's going on? ”

He pointed to the guards at the entrance of the cemetery.

Sean sighed and said, "If what I saw before was correct, it seems that a marshal went in to hold an event, so he was on alert." I saw that you seemed to have been blocked out just now, so I came over to say hello. ”

Lu An's brows furrowed even tighter, Marshal? Activity? Why did you pick such a time?

However, he immediately reacted, the 10th anniversary commemoration?

Sean saw that his face was pale, and explained with a smile: "However, you don't have to worry, it's been more than an hour in and it should be almost over." ”

Lu An nodded, and also asked with a smile: "So, you waited here for an hour?" ”

"yes."

Zone Zero at 23:52 on August 24.

There is not much time left until 0:17 on August 25, and it seems that this time it is really going to be missed.

Lu Anxin sighed, looked up and asked, "Are you here ......?"

"Sister, what about you?"

"Father."

Both of them fell silent.

"Speaking of which, it's the tenth time."

"yes, ten years."

Between their eyes, the two suddenly sighed in unison.

Ten years ago, at 0:17 on August 25, Lu An's father died, and the war ended.
