A few days later, on July 1, 222 AH, at 5 a.m.

As if in the endless dark tunnel, the maglev train is speeding at a speed of 400 kilometers per hour, and the light and shadow are drifting away. The carriage was brightly lit, peaceful and silent, with the occasional slight shaking of the train and everyone drowsy.

There was an eye-catching girl sitting by the window, her miniskirt and sleeveless cheongsam top made her petite body even more petite, and her snow-white limbs were exposed to the air like white bamboo shoots, which was simply Lolicon's poison!

"Ah~I'm so tired~"

Zhou Nan yawned, which suddenly attracted the eyes of the surrounding uncles, and they all looked over and saw the girl's outstretched arms and developed biceps......

This is a muscular Lori.

"Uh......" The uncles were disappointed.

Zhou Nan couldn't help but shudder: "Suddenly I had the urge to beat people." ”

The town of Yandang, where he served, was a rather remote border town, belonging to the northernmost city in the current country: Xianxia City. As it is a frontier-level county-level agricultural town to be developed, Yandang Town currently has no magnetic levitation, and only a highway tunnel is connected to Linzhen. Zhou Nan first had to arrive at Shiran County, a county-level city with maglev, and then take a maglev train through nearly 20 cities to reach his destination.

Since the car is in the tunnel almost all the time, the windows are directly adjusted to opaque mode. At this time, a row of red letters flashed on the black window: "The train is about to arrive in Yuheng City, please prepare to get off the train if you need to get off." Then a radio of the same content sounded in the carriage.

Soon, the train began to slow down.

This indicates that it is about to drive out of the tunnel.

Due to the high speed, when the train exits the tunnel, the air pressure is too high, causing an air explosion at the entrance of the tunnel. If it is on the ground, it is the same, because there is enough space there, and this is a closed underground cave, even if this cave is slightly larger than a cave in the general sense, any loud noise will be amplified, so the train must slow down.

Four minutes later, even though the windows were still dark, you could still feel that the train was moving smoothly at a low speed.

At this time, the opaque windows slowly become transparent in order to adapt to the changes in the environment, and the green forest outside the window enters people's eyes, which makes people feel refreshed.

This is a large dense forest, dominated by three types of plants: tall evergreen broad-leaved forest, evergreen shrubs and shade-loving herbaceous plants, and multi-level greening helps the carbon and oxygen cycle!

The scale and diversity of vegetation far exceed that of Yandang Town, and the sky is high and cloudy......

No, it's underground!

Unlike the false sky in Yandang Town, since the highest point of the cave in Yuheng City is 400 meters, the sky simulated by the display screen covered by the dome roof is extremely realistic!

In addition to the stunning sky, the cave's towers support the wide roof like pillars, and the high-rise buildings are lined up one after another, with angular houses embedded in the walls of the cave and all roofs covered with greenery. Cable car systems, roads and rail transit stretch like spider webs from the four walls to the center of the city, through large wooded areas, and across the many lakes and rivers.

This is Zhounan's destination.

Yuheng City, the fifth city in the capital area, has a spindle-shaped space volume of more than 20 cubic kilometers, covers an area of nearly 110 square kilometers, and has a population of up to 200,000.

Compared with here, Yandang Town is simply the difference between ants and elephants.

The hovering train slowly shuttled through the forest at a speed of 20 kilometers per hour, and everyone in the carriage stared out the window intently, quite excited.

In the distance, there are a large number of buildings of various forms throughout the cave, while in the suburbs, the builders supporting the roof of the cave are all columns covering an area of 100 meters square. Crops are planted on all floors of the square buildings, land use is increased by dozens of times, and climate control allows crops to grow twice a year, and the end result is a staggering 67% food self-sufficiency rate in a large city with a high population density like Yuheng.

This was a miracle before.

No, even now, this is a high technology that is difficult to fully promote. In this small gathering area of Yandang Town, ordinary ground planting techniques, crop varieties and an artificial climate with three crops a year are still carried out, making more than 100 agricultural market towns and cities the granaries of this underground country.

Suddenly, on one side of the car, the people lying on the windows of the car exclaimed, sweeping away the lethargic atmosphere caused by the long journey in the car.

"June Waterfall! June Waterfall! ”

"Oh, oh, oh!"

Thousands of meters away, a snow-white waterfall cascades down from a hundred meters into the dense forest. It is known as the "June Falls", an underground river waterfall that only appears in June every year and lasts for two months. Due to the loud sound of the waterfall, it can be quite disturbing in smaller cities, so it can only be seen in a few large cities with plenty of space.

However, Zhou Nan was not interested in that natural scenery at all, or rather, she was tired of it.

She looked down at the information on the tablet, her brow furrowed, her lips curled in displeasure.

The Ninth Central Preparatory Military Academy, the ninth of the nine Central Preparatory Military Academy, is committed to cultivating future professional soldiers who are proficient in their profession and have perfect personalities.

The school is located in the western suburbs of Yuheng City, covering an area of 1 square kilometer, divided into four majors: gunnery, knife, security, and intelligence. It has 12 professional courses: individual tactics, sniper science, knife art, intelligence, combat command, communication technology, combat case study, mechanical engineering, unmanned aerial vehicle operation, engineering, basic science, applied science, and 8 major general courses: mathematics, literature, history, shooting, ballistics, military psychology, humanities, national security affairs and public affairs.

……

"It's absolutely deliberate, it's all text, can't it be illustrated with pictures!"

Zhou Nan seemed to see the ugly face of the battalion commander Huang Haiping: "Hey, hey, I'll bully you for not being literate, ho ho yo make a fuss." ”

Zhou Nan pouted and said: "Who is illiterate, I just can't recognize it all!" ”

It is really difficult for the military to arrange such illiterate people into military schools.

The train slowly stops at Yuheng Station, a large station with four platforms and four maglev tracks. As for the station's eerie main building, most people say it looks like a turtle shell, but officials say it's a steel helmet. Both are pretty much the same anyway, whatever they say.

Zhou Nan stood in front of the station with an electric suitcase, looked at the building, and tilted his head: "No matter how you look at it, it's a turtle shell." ”

A small yellow taxi slowly stopped beside Zhou Nan: "Hey! Little beauty, do you want a car? ”

"Remove the word 'small', and you will want it."

“OK！” After the young driver with the colorful cockscomb head got out of the car, he picked up Zhou Nan's suitcase, "Beauty, please get in the car." ”

A small yellow two-seater electric taxi drives down the road, and dynamic music is playing inside the car.

Due to the well-developed public transport system, there are not many vehicles on the road, so the road has only four lanes. In addition, in order to conserve resources, almost all vehicles are small and medium-sized cars. As for driverless technology, it is only used in private cars, and public transport is still manned.

"Cockscomb, are you a bad boy?" Zhou Nan in the passenger seat said curiously.

"Of course, beauty, do you want to treat you badly."

"It turns out that all bad people have serious jobs."

"I'm a good role model locally."

"Oh."

"Beauty, you haven't said where you're going."

"Go to Tongji Cemetery, wait, take me to buy a bouquet of stars first."

"Starry? It's hard to find. ”

"Then I'm going to trouble you, bad model." Zhou Nan showed a smile like a poisoned Lori.

"Okay, leave it to me, beauty!"

Tongji Cemetery is semi-surrounded by rivers and has a beautiful environment, the whole cemetery is divided into two parts, one side is a piece of military cemetery, and the other side is a forest of steles composed of tall civilian tombstones.

Most of the cemetery is a military cemetery, and the military cemetery is divided into two parts, one part is a pyramid-shaped tombstone about 1 meter high, one side is engraved with the name and epitaph of the deceased, and a tombstone can be used by 4 people; The other is a tombstone that is used independently by a single person, and the area occupied after death also shows the degree of contribution to the country during the deceased's lifetime. In this era, only soldiers are eligible to use independent tombstones and own cemeteries after death, and endless tombstones show people the honor of soldiers.

The area of the park of the civil stele forest also accounts for only one-tenth of the entire cemetery, the stele forest is composed of tall black cubic columns, occupies a square area, the side length is 1 meter, the height is nearly two meters, and the four sides of the black artificial marble are engraved with a large number of names. At a time when space is scarce, one such tombstone can be used by 400 deceased, and in this "Tongji Cemetery", there are 108 such tombstones, and even so, the scale of the stele forest is still expanding.

Zhou Nan, who has been retired, came to visit not soldiers, but civilians.

Standing in front of the tombstone that was much taller than himself, Zhou Nan stared at the dense names in front of him, and there were more than a dozen names in the middle of the tombstone that were additionally marked by a rectangular frame, and the first line inside read: The Seventh Orphanage.

In the case of a mass fatality, the name of the deceased is additionally framed and the location of the accident is marked.

Zhou Nan smiled, his expression was so relieved and indifferent: "Everyone, I'm coming to see you, and I will come often in the next two years." ”

put a bunch of stars in his hand on the ground, but Zhou Nan's movements suddenly stopped, because there was already a bunch of stars on the ground that was exactly the same as the package in his hand.

The starry sky is the teacher's favorite flower, a delicate and delicate flower loosely gathered together, symbolizing the innocence and love of all the children in the Seventh Orphanage, as well as the ......

Thoughts and true love.

"......" Zhou Nan was stunned for a moment, then looked left and right, and then ran in the tall stele forest, searching, and finally shouted excitedly: "Xiao Yi!" Xiaobai! Quietly! Are you guys here! ”

However, no one responded to her anticipation and joy.

Except for a few flying birds, there was no sound nearby.

There were four surviving children in the No. 7 Orphanage that year, and they hadn't seen each other for two years.
