In 2055, mankind mastered controllable nuclear fusion technology, and the first nuclear fusion power generation unit was put into operation in the Taklima Desert in China the following year. From then on, mankind entered the era of nuclear fusion energy.
In 2059, humans mastered cell repair technology, and a lung cancer patient who was cured using this technology was born in the same year, and humans entered the era of cell medicine.
In 2065, the United Nations General Assembly adopted a peace treaty to destroy all nuclear weapons and related technical equipment.
In the same year, a development treaty was passed, and only "Chinese and English" were retained as common languages, and the borderless era began to take shape.
In 2078, the referendum that lasted for half a year ended, the concept of nation became history, the Earth Alliance was established, the northern capital of China became the headquarters of the alliance, and mankind officially entered the era of interstellar exploration.
On December 31, 2099, a sudden change occurred, and fire rained down from the sky without any warning.
Human civilization suffered a devastating blow. Except for China's "Dragon Heart" nuclear fusion reactor, which was preserved, reactors on other continents exploded one after another.
The last message came from the North American continent.
"Here they come"
Only the surviving humans know that humans are not alone in this universe.
--------------------------
20 years later
In Jiashan City, 300 kilometers south of the northern capital, there was another round of stern preaching in the farmyards on the outskirts of the city.
"Only when you are upright can you protect your family; only when you are skilled in skills can you protect your country."
A middle-aged man in his forties was pacing back and forth in the small courtyard, reprimanding the young man in front of him sonorously.
This man's name is Liangtian, heir to a martial arts family. He returned from retirement 4 years ago with gray hair and his left arm is missing.
This kind of injury can be easily treated with current medical standards, but he insisted not to go to the hospital, and did not even mention a word to relatives and friends who cared about him. As time went by, no one cared about him.
A 28-year-old boy stood motionless in front of Liang Tian.
There are sandbags weighing ten kilograms each hanging on his wrists, and a burnt bamboo incense is held between his fingers. This young man is the son of a good man.
He has been practicing this kind of physical training for eight years. He once complained about why he had to practice physical training for four more years, but after being taught by Liang Tian, he never asked this question again.
The practice of good words starts at 5 a.m. and lasts until 8 a.m. Today is the practice of basic skills. After burning the bamboo incense between the fingers, today's practice is completed.
The process of exercising the muscles, bones and skin externally and practicing internally in one breath is boring and boring.
However, Liangyan can be considered a little talented. Although he looks about the same size as his peers, the energy contained in his body's muscles can be dozens of times higher than that of his peers.
"Okay, stop practicing, go take a shower and have breakfast, and get there early for today's graduation review."
After saying that, a petite and beautiful woman came out of the kitchen carrying porridge and vegetables. This beautiful woman was Wang Chenchen, the mother of good words.
Wang Chenchen and Liangtian knew each other before the disaster. They were childhood sweethearts. After the disaster, they got married and gave birth to Liangyan and his sister Liangru.
Liangyan grinned and helplessly looked at the bamboo fragrance between his fingers.
The quality of the bamboo incense made by my father this time was a bit too good. The previous bamboo incense should have burned out ten minutes ago, but now this incense is still stubbornly emitting green smoke, and there will be no sign of extinguishing for a while.
Time passed by minute by second, and Liangyan's body began to shake unconsciously. Finally, twenty minutes later, the bamboo incense drifted out with a burst of thick smoke and slowly extinguished.
Liangyan fell to the ground stiffly, and his extremely exhausted body almost made him comatose.
However, he must not faint at this time, otherwise the blocked breath will cause great damage to the body.
Liangyan took a deep breath and activated the method of controlling Qi.
The family tradition says:
The method of controlling Qi is to guide the circulation of spiritual energy in the body, and spiritual energy can strengthen the physical body.
Therefore, whenever he has done basic training, he will use the method of controlling air to relieve the fatigue after training.
Today is the day for Liangyan's graduation review. If he successfully passes the review, he will be able to enter the virtual network. He has been looking forward to this day for a long time.
The virtual network is a brand new online world built by the alliance government after the natural disaster. The landforms and buildings here are exactly the same as those in real time.
Here you can learn about the entire human world, but in order to protect the neurological development of minors, the government stipulates that only citizens who are over 16 years old and have passed the assessment are allowed to access the virtual network.
There were not many people applying for graduation review today. When Liangyan walked to the school, he did not queue up and went directly to the review.
The content of the review is also very simple. It tests the strength of the nervous system, takes a psychological test, and the test results come out in 20 minutes.
In the end, Liangyan successfully graduated with nearly perfect scores in cultural courses, physical education courses, and comprehensive physical education.
Liangyan is not very surprised by this result, because he has been practicing since childhood and his five senses of thinking are very sharp and his concentration is extremely strong.
It was very easy for him to learn the basic knowledge in the books, and his body functions were convenient and several times stronger than those of ordinary people.
As soon as he walked out of the school complex, his communicator rang.
The first person to call was the military. The other party first congratulated him, then invited him to visit the military, and finally ended the conversation by saying, "The people need you."
The second is that the processes of the Beito government are similar to those of the military.
The third one is an organization that calls itself "The Path Leader".
In the end, Liangyan simply shut down his phone, and some strange organizations from the province came to disturb him again.
Walking on the playground of the campus, looking at the scattered kind words of students on the playground, I recalled every bit of my time when I was still in school.
The cultural courses ended two months ago, and most students gave up on the graduation review because it was impossible for them to pass the graduation review.
Suddenly, a strong and powerful fist came from behind with a fist blow, and he reacted instinctively when he sensed the danger and good words.
He slipped forward and dodged the sneak attack. Seeing that the sneak attack was unsuccessful, the sneak attacker immediately changed his fists into claws and prepared to fight head-on.
However, Liangyan did not prepare to fight back, but just shouted helplessly:
"Second brother, stop making trouble, okay?!"
When Liu Jing heard what he said, he retracted his hand in dismay and said cheerfully:
"Haha, San'er, you've become a lot stronger after a few days! How was the review? You passed it with full marks, right?"
Liu Jing's character is like this. He is carefree, loves to cause trouble, and has a strong sense of justice. The more trouble he makes, the more he likes it. This school has a strong learning atmosphere and the harmonious relationship between classmates is a credit to him.
Liang Yan was already used to Liu Jing's sneak attacks. Ever since he started practicing martial arts four years ago, sneak attacks had become Liu Jing's way of greeting him.
However, this is only for good advice. Their eldest brother Qin Mu and Liu Jing would never dare to do so. He still remembers the pain of breaking his arm three years ago.
Liangyan nodded confidently and said:
"Almost full marks. You were right to do the early graduation review. But my classmates have graduated and gone their separate ways. I wonder if there will be a chance to meet again."
Speaking of this, he thought of his deskmate, the lonely and stubborn girl.
Her classmates all thought she was too cold, so cold that after eight years, only Liangyan was willing to make friends with her.
But only Liangyan knew the fiery heart of that girl and the world-famous face beneath that simulated mask.
Seeing God's good words gone, Liu Jing chuckled.
"Xiaoli, you're here!"
Hearing the word "Xiao Li", Liang Yan immediately came to his senses and looked around excitedly.
When he saw Liu Jing's confused and weird expression, he immediately realized that this was Liu Jing's prank again.
Liu Jing asked in surprise:
"San'er, could it be that you have really been drugged? You are indifferent to the thoughts of all the flowers in your class, but you care so much about that country girl?"
Liangyan didn't understand why he cared so much about that girl. He argued feebly:
"She has been my deskmate for six years, can I not care?"
Listening to Liangyan's weak defense, Liu Jing was in a good mood, and teasing the third child was his daily pleasure.
"Hey, look at how cowardly you are. But don't you really want to get in touch with your kind of flowers?"
"What are you talking about? Come on, let's go. I've made an appointment to go to the service bureau. Don't be late."
After saying his kind words, he strode away quickly, and Liu Jing followed him with a wicked smile on his face.
Twenty minutes later, they arrived at the Network Service Bureau. Liangyan was relieved, and Liu Jing teased him all the way, which made his head feel big.
After passing through the light curtain door and dust removal tunnel, Liu Jing came to the service hall with good advice. Thousands of dormant pods were quietly placed in the work area, and each dormant pod had a user connecting to the network.
Liu Jing patted Liangyan on the shoulder and whispered:
"San'er, your first connection to the virtual network may be a bit slow. I'm waiting for you in the waiting hall. You can find me by entering my personal information in the waiting hall. You can just follow me later."
Liangyan nodded seriously. He had heard about the magic of the virtual network countless times, and he was still a little uneasy about being able to enter this virtual network soon.
After moving his body, he followed Liu Jing's example and lay down in the sleeping cabin. The cabin door slowly closed, and Liang Yan's vision gradually blurred.
Then a pleasant sound sounded.
"Hello, good advice, don't panic, the system is synchronizing your brain waves."
"During synchronization, I will briefly introduce to you the precautions for entering the virtual network.
1. Everything that happens here will be recorded. When you return to reality, the relevant departments will decide whether to arrest you based on the records. You must also be a law-abiding citizen here.
Second, except that you will not die here, all other feelings are synchronized with reality. Please do not do dangerous things here.
Third, except for red areas that require special approval, you can enter and leave other areas at will, but in order not to affect real life, you are only allowed to enter the virtual network for eight hours a day."
As the introduction of the system ended, Liangyan appeared in a white room with an information desk standing in the center.
Liangyan walked up to the stage and entered Liu Jing's personal information and clicked send. Instantly, the white room switched to a coffee shop, and Liu Jing was sitting opposite, waiting for him.
Seeing the confused Liangyan, Liu Jing smiled and asked Liangyan to sit down.
"San'er, how do you feel? This is a virtual network."
Liangyan pulled up the chair and sat next to Liu Jing. He pinched his arm, which hurt a little, and then felt the temperature of his lower lip with his fingertips. It was exactly the same as reality, and he was even more confused.
Liu Jing was speechless seeing how confused he was.
"Look at how cowardly you are. If you are like this at this level, you will be scared to death after a while..."
"Scared to death? So exaggerated?" Liangyan muttered in confusion.
When he raised his head and was about to ask, Liu Jing had already stood up and walked outside.
"San'er, let's go. I won't drink any more coffee. I'm going to find the boss."
"oh"
Liangyan followed suit.
After walking out of the coffee shop, a wave of heat hit his face. Liu Jing patted Liangyan on the shoulder and said:
"San'er, look at the sky."
Liangyan raised his head and saw a city with many tall buildings standing silently upside down in the sky.
This suspended city is like a mirror reflecting the entire city. The inverted city gives people a huge sense of oppression. Liang Yan feels that it becomes difficult to breathe.
Liu Jing saw Liang Yan's embarrassment and said leisurely:
"San'er, have you seen it? This is the "Mirror World - Hanging City"."
Hearing the kind words from Liu Jing's voice was like a breath of spring breeze, and my tense nerves suddenly relaxed, and the hanging city in the sky no longer felt as oppressive as before.
