At night, when they returned to their rooms, they were much quieter than before. Sun Shifang quietly tied the door, skillfully hung the clothes into the hanger, and laid the bedding.

Then, he pulled out a yellowed photo album from his backpack and flipped to the page where the line was opened.

"There are still people alive in the picnic area." Sun Shifang looked at the smiling family in the photo.

Back then, they thought picnic areas were just common pollution, which they were used to living outside the city. There used to be factories around them that drained sewage, causing a lot of people to get sick, and when they got into trouble, they got a large amount of compensation and planned to move to the urban-rural area.

It was also that day, in the midst of constant coughing, taking the medicine prescribed by the hospital, holding their luggage, and preparing to leave, they passed by the only photo studio in the township.

At the suggestion of their younger brother, they took a beaming photo.

At that time, Sun Shifang didn't know that exchanging his body for money was the most helpless thing.

Because their family naively felt that it was just a cough, at most diarrhea, they could get tens of thousands of yuan in compensation for each person, which was really worth it.

In that photo, their faces showed such joy.

Father and mother are dressed and don't know what pose in front of the camera. He held his mother's shoulder.

The two younger brothers sat in their chairs, restlessly comparing the V-signs they saw on their phones.

The youngest sister tugged at the corners of her clothes.

After moving into the rural-urban area, they bought a small house and began to renovate it themselves. They finally don't have to sleep in a small hall crammed into a small hall as a family, and they don't have to see people squatting on the pit while they are stir-frying. They had their own toilets, kitchens, and a small yard.

Subsequently, the pollution of the picnic area made the officials pay attention, and the era of the Great Evacuation arrived.

Sun Shifang still remembers that many police cars and transport trucks have arrived here, and the mediators from the township have also arrived. They persuaded Sun Shifang's family to leave the city, and offered compensation as before, and told them that they would have a new home in Yanjiang City.

Most people agreed, and if they could get into a better city life and have money, why not do it.

Except for the younger brother.

At this time, my younger brother had graduated from vocational high school, and he also heard the news of the evacuation from his friends. But he didn't plan to leave, he wanted to stay here.

Because they have heard that once evacuated, these lands will be completely unowned. Then they can completely own these places, and when this pollution passes, they will have bigger houses, they can plant a large field, and they can run freely on the vast land.

That's my brother's dream.

In this way, the younger brother insisted on staying on the huge land, watching the family evacuate to the city along the river.

In the days that followed, the black tower began to be built, and the news of his younger brother and the people who had been outside disappeared little by little.

"Hope you're okay...... bar. After hearing so much news about the picnic area, Sun Shifang's heart no longer has despair and sadness, but is ready for the worst.

In the other room, Zeng Xing slept soundly, he had nothing to worry about, he could earn more money, and he could make some contributions to the city, so why not.

On the contrary, Bing Shijue, tossing and turning in bed, he used to think that the danger of the picnic area was just pollution, and he just had to follow the large army closely and not enter the high-risk area. According to what we know so far, danger can be said to be everywhere.

You can give up, but what about your parents, their bodies can't wait for them to use legal and reasonable means to earn money and buy drugs.

And after hearing these news, he realized how much his parents paid for going to the picnic area back then.

How could I hide in the city and watch them grow old in bed day by day?

"Caution is the number one priority." Bing Shijue rubbed his eyes and glanced at the time on his wrist again, "Sleep." ”

The last brightly lit room was Luo Rong's room.

He was checking the mechanics of the firearm, pressing the ammunition into the magazine one by one. Then he listened to the sound of a collision that made him feel more comfortable, and placed the pistol on the bedside table.

"It's going to go again." Luo Rong took a deep breath and let the pictures of the past emerge in his dry mind, in the days when he was as old as these newcomers. This small unfinished square is so lively, people don't know the dangers of the picnic area, and enthusiastically and unrelentingly want to contribute to the world.

One by one, his comrades fell, and one by one he grabbed his own neck and drowned in the air.

There are also people who die at the hands of their compatriots.

There were even people who betrayed directly.

Since that time, the work of field exploration has been extremely rigorous, and it has to be screened one by one.

Luo Rong became the only surviving explorer in Yanjiang City and became the captain.

"Sleep...... A few days of training can also be tiring. Luo Rong turned off the light and fell into a peaceful sleep in the smell of lubricating oil.

The next day, Luo Rong began to let the three of them wear glasses, and in the virtual projection, they could adapt again and again to the huge amount of information in their eyes, or how to react to the red area they had never seen before.

In this training, Bing Shijue has always come out on top, and he naturally got used to the huge amount of information brought by the picnic area, and tried to find his place in it little by little, and re-condense into his true form. It also smoothly accepts the data flow after wearing glasses.

"Brother Bing, how the hell are you used to it?" After three days of training, Zeng Xing sat in a chair and pressed ice water against his temples, trying not to vomit.

"Maybe it has something to do with my profession and the fact that I've played games when I've been idle before." Bing Shijue took a deep breath, he took off his glasses, and felt the blood vessels around his eyes and temples beating, "but he didn't get used to it that quickly." ”

"It's a lot better." Luo Rong stood in the distance, turning off the projection scene, and asked the medical staff on the side to help Sun Shifang up, "Little Sun, are you okay?" ”

“…… I'm fine. Sun Shifang covered his mouth with his palm, "No problem." ”

"In fact, people who do mental work in reality, or have been exposed to VR, can adapt better than you." Luo Rong checked the previous information, "But in reality, people who do these two kinds of work are basically not willing to come to the picnic area, they have a lot of income and a stable life." ”

"Even if you do recruit it, you may not be able to pass the immune test, right?" Bing Shijue drank ice water and said after a long sigh of relief.

"Yes, that's why the picnic area is now exploring the polar regions, and the output of immunoassays is basically fixed every year." Luo Rong handed over the tablet at hand to the staff and sat down in front of them, "The annual quota for each city is 1,000. ”

"Can't you be more accurate?" Sun Shifang stood up on the stool and shook his head.

"If it's accurate, it's not called a test, Xiaofang." Zeng Xing said.

"Xiaofang, this sounds good." Luo Rong smiled, "Just like Zeng Xing said, because we can't determine the specific situation, we can only bump around like headless flies." ”

"If I'm right, the production of immunoassays should be related to the progress of the picnic area." Bing Shijue threw out the questions he had been thinking about in the past few days, "For example, a certain plant from the picnic area, or it can only be done in the picnic area." So the larger the scope of exploration, the higher the yield. ”

"That's right." Luo Rong nodded, his face full of relief, "Now for those of us in the city, the headache is two points, output and screening speed. ”

"Captain Luo...... What happens if you don't have someone who passes the immunization test, when you leave town? Sun Shifang hesitated for a moment and expressed his doubts.

"If it's the era when picnic areas have just spread, then you can live a normal life." Luo Rong said, "For example, our parents, or think back to when we were children. In fact, the impact is not big. We all have some picnic areas polluted in our bodies to a greater or lesser extent. ”

Speaking of this, Luo Rong inadvertently glanced at Bing Shijue.

But Bing Shijue actually noticed his sideways gaze and turned his head to look at him.

"Captain Luo wants to say that I was born before 1999, and there should be pollution in my body theoretically, so there will always be a reaction, but the previous test was not correct, right?" Bing Shijue said.

"That's right, that's what we researchers are curious about." Luo Rong was not taboo, "We found out the information about your fever when you were three years old, but it doesn't seem to be useful." At that time, technology was not developed, and your test results were no different from ordinary people, and blood samples were not kept. The results of the collection now can only be obtained, and you probably won't react to the picnic area. ”

"It's a coincidence, just like a deadly virus may not be okay for some people."

"Ah...... I know, it's like it's called Typhoid Mary, right? Zeng Xing slapped his palms and shouted loudly.

"I think I've seen it...... Just last night. Sun Shifang fumbled for the phone in his pocket and slid effortlessly across the screen.

"Yes, but that's not the point." Luo Rong waved his hand, "We're going to leave for the picnic area this afternoon, have a good lunch, don't bring anything else, put on our most comfortable clothes, and gather here." ”

"Yes!"

"But it's really a rush of training time." Bing Shijue quickly finished a meal in the cafeteria, looking at the staff who were full of tired faces and were discussing carefully during the meal, "In reality, soldier training takes three months. But our training lasted only three days...... Xiaofang, she didn't even know how to go to the picnic area. ”

"Thinking about it from another angle, picnic areas are getting more and more polluted. However, the output of the agent has been consistent. had to send people out to explore...... But this picnic area. ”

"Bad luck picnic area." Thinking of this, Bing Shijue couldn't help but raise his head to look at the warm ceiling of the cafeteria, this alien who flew over the earth casually discarded a puddle of garbage, but brought an irresistible disaster to mankind.

"There are too many desperate situations for human beings to explore picnic areas and expand the scale of ordinary people's habitation, but ordinary people simply can't bear the pollution of picnic areas. It can only be dispatched in small teams, but the number of small teams is too low, and the mortality rate outside is high, which will reduce the production of potions. ”

"Maybe I can do something for Yanjiang City." Thinking of this, Bing Shijue smiled bitterly. The sense of responsibility that I once had as a teacher has not withered in my heart.

He doesn't think he's a world-famous teacher, and he doesn't think he can teach every child.

But if you can let one or two children learn some knowledge, understand some truth, and generate a little enthusiasm.

That's enough.

and...... Just don't die. ”
