The protagonist or one of the protagonists of this story is called Du Yande, he is a person born in the last year of the seventies, and he finally caught the last train after the seventies, but because the time period was too embarrassing, he finally made the post-80s say that he is too old, and the post-70s say that he is too young, but he is very unhappy to be sandwiched between the seventies and eighties. Since childhood, because of physical problems, he has been weak and sickly since birth, because he is an only child, he has caught up with the good policy of family planning, and the medical expenses from childhood to adulthood have been reimbursed, and he has enjoyed the country's care for the only child. Later, the family felt that it was not a matter for him to continue to be in front of the medicine jar, and he was sent to practice martial arts at the age of eight, although he learned all performative martial arts, and he was always the target of various bullies at school, and the various performative martial arts he learned were regarded by the family as all kinds of assets to show off and were required to perform in various places. When he was in the eighth year of martial arts training, he was forced to learn judo due to his family's requirements, and after only three months, the ribs that had been more than ten years old were immediately covered with all kinds of fat, and the change from a bean sprout to a potato made him hate Japan like a mortal enemy. He was of ordinary height, ordinary appearance, and ordinary economic status, and he was tossed by various transformations for three years when he mixed into the army, and after returning home, he had nothing to do for a while and then borrowed the east wind of the university's expansion, and finally became a college student, but when the story happened, he couldn't remember all kinds of courses that had nothing to do with his work. Fortunately, I have been crammed by my mother for many years since I was a child, and I finally deceived a girl who "married the wrong man" to become a wife by relying on my well-spoken mouth, and I have a lovely daughter, but I finally don't need to celebrate "11.11" every year.

Du Yande's job is a very simple work like an assembly line, that is, using a grinder to crush the camellia seeds to produce oil and then send them to the next process, which is outrageously simple. If it weren't for the fact that there were various problems with the computers in the factory that needed his help, most of the time he would wonder if he didn't need to spend three years in college, of course, except for the "education allowance" on the monthly salary slip.

On the day of the story, he did not go to work and the factory had to shut down due to a mechanical failure. This is almost the happiest time for the operators, because while the comrades of the maintenance team are working hard to repair the machines, they can find various opportunities to rest or even take a day off directly. Often, at this time, the brothers on duty would leave the factory in droves to visit the nearby business district.

Du Yande has a motorcycle, so it is also a very good means of transportation in this city that does not ban motorcycles, as long as you don't go to drag racing, it is still very safe and convenient, at this time, he is driving in the direction of the business district with two colleagues in the same class.

Behind him was Yang Minghuan, medium height, relatively slender figure, his hair fluttering with the wind blowing when the motorcycle was running, and from time to time he wiped the tears that were blown out of the corners of his eyes with the back of his hand. He originally graduated from the computer department of a university, because computer education was widely carried out in various universities in the following years, and he failed to find a good job after graduating with excellent grades, and finally chose to work in this tea oil factory after sitting on the assembly line in a battery factory for a long time. Behind Yang Minghuan sat Sun Wenbin, who was stronger and slightly taller than Yang Minghuan. Sun Wenbin, a high-achieving student who graduated from an agricultural university, originally entered the university with complete ideals, determined to become an agricultural expert like Yuan Longping, but was later overshadowed by the terrible base of the Chinese population, and finally entered the factory to become a squad leader because of his participation in the water enzymatic tea seed oil program in college.

At this time, the three people were about to go to the Agricultural Bank in the center of the business district to withdraw money, and then went to a nearby fast food restaurant to have a meal and then went shopping.

The motorcycle came to the door of the bank after five minutes of running, and Yang Minghuan and Sun Wenbin quickly ran to the ATM after getting out of the car, while Du Yande had to find a place to park the motorcycle. In front of the bank is a sidewalk about five meters wide, because it is full of all kinds of parked cars and it is difficult to find a place to park motorcycles, seven or eight meters to the north, there are several stalls on the sidewalk, and a little farther away a member of the urban management team is sitting behind an information desk to rest. Then an unusual thing caught his attention for a moment, a black Santana car was parked on the side of the road, the window was pasted with sunscreen film and could not let people see the situation in the car, only vaguely saw three or four people sitting in it motionless, although it is not too hot in the solar calendar of June, but sitting in a black car under the direct sun is definitely not a pleasant experience, not to mention that the car is still in a state of engine stoppage.

"Maybe it's waiting for someone." Du Yande muttered to himself, carefully reversing the car and parking in the motorcycle parking area. At this time, a black armored cash truck not far away was slowly driving towards the main entrance of the bank, and Du Yande, who saw this situation, suddenly had a strange feeling in his heart, and he suddenly felt that several people sitting in Santana were here to rob the cash truck. Thinking of this, he couldn't help but shrug his shoulders and smile, and secretly cursed in his heart, "I read too many urban novels" and then began to lock the car.

The process of locking the car is not cumbersome, because the car has been installed with a GPS positioning system, even if someone is driven away, it can be quickly located and call the police for help, so he simply didn't even bother to lock the big lock, in a large number of big locks around, this scooter without a big lock is particularly conspicuous, when he turned off the power switch to the spark plug, and then got up and walked to the bank. At this time, a large group of people in the bank were queuing up in front of the counter to handle business, Yang Minghuan and Sun Wenbin were each handling business in front of an ATM, and when they saw him coming over, Yang Minghuan also waved to him.

The cash truck behind him was backwards and approached the door of the bank, and the moment Du Yande walked up the steps of the bank, just as the cash truck opened the door, two security guards with shotguns in their hands walked down from the back door, and then a staff member walked out of the car with two boxes containing banknotes. Du Yande habitually looked sideways as these people carried out their movements in an orderly manner, and stepped on the steps with one foot. Suddenly, he caught a glimpse of the Santana, and in that instant, his blood was almost clotted. The two people who were getting out of the car were wearing three-hole masks, and it was not to keep their faces warm when they went out on a hot June day.

The security guards who were stunned on the spot also spotted the two people wearing masks for the first time, but because there had never been a bank robbery in this city, their relaxed nerves could not be tensed for a while, and the security guards who were holding money hesitated to try to change the shotgun in their hands to a gun position. At the same time, with the sound of a "bang" gunshot, the people in the car fired a direct shot at the few people who were still hesitating, and the white smoke suddenly erupted, and because there was no wind, Santana's window was shrouded in gunsmoke. The staff carrying the cash box jumped up as if stung for a moment, and the two cash boxes in their hands also fell to the ground.

Yang Minghuan, who was walking out of the door, was stunned, and only came to his senses after a little stunned, and quickly retracted sideways into the bank. Du Yande reacted a little faster, and the moment he saw the black mask, he took three steps and made two steps and jumped directly into the bank gate, leaning sideways against the wall and continuing to observe the situation on the sidewalk.

At this time, the crowd next to them woke up from the gunshots, and for a while they were so frightened that they couldn't run on the ground and rolled and crawled, they got rid of their high heels and ran barefoot, and several old people who were obviously not very good also hurriedly walked away to both ends of the sidewalk. The stall not far away was overturned by the panicked crowd, and the stall owner did not bother to pick up the goods that had been knocked to the ground, and ran away into the distance. The chengguan team members who were originally sitting behind the information desk not far away were also nervous and jumped three feet high, and after hesitating a few times in rushing up and retreating, they finally chose to retreat into the distance with a big cap. Motorcycles and bicycles on the side of the road were also knocked over by the frightened crowd.

"It's good that my car wasn't knocked over." Du Yande was talking to himself, and Sun Wenbin, who had finished withdrawing the money, walked over slowly and patted Du Yande and Yang Minghuan on the shoulder, "Damn, what are you two doing here?" Do you have fireworks outside? ”

Yang Minghuan hurriedly pulled Sun Wenbin to the wall and pointed outside, saying, "There is a bank robbery outside, don't go out." ”

At this time, the staff who was hit called out, he covered his ass with his right hand and jumped into the hall with the support of a banknote guard, while another banknote officer hurriedly raised his shotgun and pulled the trigger at Santana, but found that it was not loaded, and quickly pumped the handguard to load the shotgun. At this moment, the black hood that rushed to the front had already aimed the ugly singles musket in his hand at the banknote keeper. With a loud bang, an ugly, rusty iron ball pierced the banknote's left shoulder, pierced the glass door at the bank's entrance, and landed directly on the porcelain floor. The banknote clerk flipped to the ground with an "oops", and the shotgun in his hand fell to the ground. The black hood quickly stepped forward to pick up the shotgun, and shot at the glass door to make the glass fall to the ground with a clatter, and then continued to load at the door, and the black hood that followed also rushed up, carrying two cash boxes and ran into the car, and then the black hood with the shotgun also retreated quickly to the car while guarding the entrance of the hall. Seeing that the black-hooded men had snatched the cash box, the cashier in the hall rushed out of the glass door that had not been broken, and fired two shots at Santana, but found nothing but a lot of small holes in the door and rear of Santana's car, and not even the window glass that had not been lowered. The black hood, who had not yet gotten into the car, hurriedly pulled the trigger at the banknote guard, but because the gun was only loaded with one bullet, the banknote keeper who knew the situation was not afraid to load and calmly face the empty gun in the black hood's hand. But you can't hold it up at any time, especially when you are dealing with armed bandits...... Finding that there were no bullets, the black hood threw the shotgun to the ground without hesitation, pulled out an ugly singles musket from his back, and pulled the trigger directly at the banknote keeper with a nervous look on his face. "Bang" a gunshot, thick smoke suddenly wrapped the black hood and the car behind him, the round iron bullet penetrated the shoulder blade of the banknote keeper and flew through the broken glass door, hit the tiles on the wall, and then was smashed on the hard tile, and when everyone did not pay attention to the bank, a round thin ring was bounced out of the broken bullet and rolled all the way to Du Yande's feet.

As a breeze blew away the shrouded smoke, the robbers not far away had already taken the cash box to the car, and the last black hood quickly got into the car, and the car spewed a puff of smoke and dust under the watchful eyes of the panicked crowd. The staff of the bank hurriedly surrounded and began to help the three injured banknote keepers, Du Yande raised his legs forward to help, but felt that there seemed to be something on the soles of his feet, he quickly looked down and saw that a small black ring with no luster was lying at his feet, he picked up the small ring and stuffed it into his pocket carelessly, and stepped forward to help.

It was already noon when the three of them walked out of the bank, which had been almost wrapped in cordon tape by the police, and after leaving their phone numbers, the three of them left the bank, walked directly past the information desk where the chengguan team members were sitting, and entered a nearby fast-food restaurant.

"Brother De, it looks like you just picked up something?" Yang Minghuan asked as he nibbled on a hamburger.

Du Yande nodded, took the small ring out of his pocket and put it on the table. "It's this, I don't know where it came from."

"It's certainly not a ring." Sun Wenbin picked up the ring, "For a human finger, the inner diameter of this ring is too small, and the border is quite thick, maybe it is some part of the broken glass door just now, right?" With that, Sun Wenbin put the ring back on the table.

Yang Minghuan picked it up curiously and sniffed it in front of his nose. "It's definitely not a part of the glass door, there is no lubricant at all, and there is no smell of lubricating oil, but a strong smell of gunsmoke, it can't be from those musket bullets, right?"

"Bullets don't use rings, do they?" Du Yande also took the ring curiously, "If the bullet uses a ring, then the propellant gas will leak directly, and even if the ring flies out, it is very irregular due to air resistance, and the trajectory is unpredictable, and no one will use the ring as a warhead." ”

"Not necessarily, maybe it was melted into the warhead when it was making bullets? Didn't I just hear from the police that there was another bullet on the wall that shattered, and all the pieces could not be found? Yang Minghuan grabbed the ring as he spoke, but Du Yande didn't have time to let go, so the ring was pulled by the pressure exerted on both sides at the same time.

This pull, this ring, which is not much larger than the nail cover, immediately became a large ring with an inner diameter of more than 20 centimeters, and the diameter of the material that makes up the ring was not thinned, this magical phenomenon made the three people stunned.

"This ...... This is certainly not the material on Earth. Du Yande, who stammered, immediately shrunk the ring to its original size, and hurriedly retracted his pocket, "What should we do, go back to the dormitory and study it again." It's not safe here! ”

The three of them hurriedly looked left and right for a while, but fortunately, today was Tuesday, even if it was noon meal time, there were only a few people in the fast food restaurant, and no one noticed the circle that had been stretched and shrunk just now.

At five o'clock in the afternoon, the three of them returned to the dormitory, and the three of them lived together in this dormitory, and as soon as they entered the dormitory door, Du Yande took out the ring, tried to pull it apart and shrink, and it could be easily achieved without much effort.

When the ring is stretched to a diameter of about 30 centimeters, a blue circle of light will appear inside the ring, and the circle of light emits a faint blue light, illuminating the faces of the three people white.

"Is this a wormhole?" Du Yande couldn't help but ask curiously.

Sun Wenbin hurriedly turned on the computer, checked the information of the wormhole and said: "The wormhole, also known as the Einstein-Rosen Bridge, is a narrow tunnel that may exist in the universe connecting two different time and space. Wormholes were hypothesized by Albert Einstein and Nathan Rosen in the 1930s when they were studying the gravitational field equations, and it was believed that instantaneous space transfer or time travel could be done through wormholes. This theory was proposed by Albert Einstein. To put it simply, a "wormhole" is a thin tube of space-time that connects distant regions of the universe. Dark matter keeps the wormhole's exit open. Wormholes can connect parallel universes to baby universes and offer the possibility of time travel. A wormhole may also be a space-time tunnel connecting a black hole and a white hole, so it is also called a "gray tunnel". Theoretically, wormholes are multidimensional spatial tunnels that connect white holes and black holes, which are ubiquitous but fleeting. However, some hypothesize that a strange substance can keep the wormhole open, while others hypothesize that if there is a strange substance called phantommatter, it can create a repulsion effect to prevent the wormhole from closing because it has both negative energy and negative mass. This exotic substance deflects light and signals the discovery of wormholes, but these theories have too many untested assumptions to be convincing. Sun Wenbin took the ring wormhole and looked it up and down carefully, "I'll take it, the wormhole...... Is there a metal frame? ”

The three of them looked at each other, and after a while, Yang Minghuan took the wormhole and looked up and down, "Wait, it seems that there are words on the inner circle." ”

The three of them came together and looked at it carefully for a long time, but they all gave up, thanks to the cramming education, the three of them were short-sighted, and they couldn't see the pinpoint-sized words in front of them. Du Yande in the EDC bag (everydaycarry is mainly to consider defense, tool use and mild life-saving factors in the face of emergencies, it is mainly characterized by concealment, portability, of course, practicality is definitely a must. These EDCs are not all carried with you all day long, mainly according to the needs of going to work or traveling every day, and are selected and matched. I flipped through it a few times, found a small magnifying glass, and looked closer to the light source.

The characters shown above are similar to English, but they cannot be read either separately or together. At this moment, Du Yande suddenly felt a thrill all over his body, as if he had been subjected to a static electric sensation, and at this time he realized that his fingers had inadvertently passed through the plane of the wormhole, and on the other side of the plane, he could not see his fingers sticking out.

"I'm sure it's a wormhole, you see!" As he spoke, he put his hand into the wormhole and showed it to the two. "It's amazing, after reading so many novels, we can actually encounter a real wormhole! What a godsend! Saying that, Sun Wenbin directly took the wormhole and pulled it open, ready to drill into it.

Yang Minghuan hurriedly grabbed Sun Wenbin's clothes, and Du Yande hurriedly shrunk the ring, when the ring shrunk to about 20 centimeters in diameter, the blue wormhole disappeared, and when he pulled it apart, the wormhole appeared again.

"What are you holding me for?" Sun Wenbin frowned and looked at Yang Minghuan. "I'm going to have to get over the addiction of time travel."

"Wear your sister!" Du Yande closed the wormhole again. "Do you know what plane is on the other side? It doesn't matter if it's the earth, but what if it's the bottom of the sea? Or is it in the universe? Go in and hang up directly. Even if it's not such a dangerous place, if you encounter a planet without oxygen, you will die in the past. What if it was the age of the dinosaurs? We're fragile human beings, so don't just jump into an unknown new plane. It's going to be dangerous! ”

Sun Wenbin calmed down, nodded, and asked, "Then what should we do?" If you don't even know what the wormhole is, then it doesn't matter if there is a wormhole or not. ”

"So, let's turn on the computer and just stick the camera over and take a look." Yang Minghuan made a suggestion.

Without saying a word, Du Yande directly began to dismantle the camera on Sun Wenbin's computer.

"Lao Du, you're not kind! Why don't you dismantle my camera and not use your own? Sun Wenbin has a lot of opinions about Du Yande starting directly from his computer.

Du Yande looked up at him, lowered his head and continued to dismantle, and explained: "Didn't you just find a girlfriend?" Now you don't have to video chat with other girls. ”

"Your sister!" Sun Wenbin was suddenly depressed, "You're still married, so what's the use of your camera?" ”

Du Yande hesitated for a moment, turned his head to look at his computer, and then looked at Sun Wenbin. "Don't you particularly want to know what it's like to cross over? Let's use your webcam to travel first. ”
