The more Bing Shijue walked towards the tower, the more he felt that this tower was not a building that could be built by humans alone, and the black arc began to obscure the sky and the sun, and even the dazzling colorful light was out of sight. As far as the eye can see, it is black and cannot be described.

It is on these pieces of metal that many workers can be seen wearing harsh orange clothing, constantly carrying out inspections. When the tools in their hands touched the metal, they emitted a somewhat dazzling white light. But to the ice on the ground, they looked like little ants crawling on the leaves.

Under the black blades, there were many military vehicles, but most of them were covered with black cloth, and Bing Shijue couldn't tell what kind of car it was through the uneven lines. Just subconsciously, follow the thick white lines on the ground.

As he could see the dozen or so gates in front of the black tower, and the soldiers standing guard and patrolling, Bing Shijue's throbbing and worried heart also calmed down a little. Not to mention, the ranks here are starting to get bigger. There were not only people who were just as anxious as him, but also some office workers in uniform, tired faces, and heavy safes.

It's just that those office workers seem to be standing on the left side of the white line, and they are neatly arranged.

They, on the other hand, are scattered to the right of the white line.

Although such a description, Bing Shijue has seen it on the Internet. On the official website of Yanjiang Castle, there are also basic preparations for going to the picnic area. For example, ID card, household register, family file, certificate of no criminal record, physical examination certificate. After all this is done, you have to go to the Black Tower to check and live in it for a while.

Those who pass the inspection will go to the picnic area.

Those who fail the inspection will return to their original city life.

As for what happens outside the picnic area, it is all confidential.

Bing Shijue's parents also strictly adhered to this.

"Picnic area...... What the hell does it look like. Bing Shijue has only seen some images of the picnic area in textbooks, or in some videos that can be published. In a word, it is unusual and illogical. It's hard to put into words.

"If you go out to take the subway, follow the left side of the white line, and if you want to sign up to go to the picnic area, go to the right." The shrill horn sounded, causing Bing Shijue to raise his head. Look at the huge horn in the middle, and the route that diverges off on the ground.

and, with guns, the sentries standing straight.

Next to the sentry, there is a QR code for registration. In a burst of "Didi Didi" code scanning, Bing Shijue and the others in the team got their own numbers and simply filled in their personal information.

But other than that, the website scanned by this QR code has no extra information.

"Very strict...... Bing Shijue looked around, and after a turn, he slowly regained his original sense of space. Because when facing the black tower, there was only an expanding line of sight and the black walls in the sky. Now that I turned around and walked slowly against the wall, I could catch a glimpse of the fireworks in the city.

It's around four o'clock in the afternoon, and some schools are already out of school in the far part of the city, and some shuttle buses are starting to leave the origins around the city, taking people from work or from school to home.

"Number 43, Ice Awakening." This time, the voice came from in front of you. Bing Shijue, who was advancing along the procession, suddenly turned around and found that he had come to a small iron gate with a steel guardrail. Several soldiers and volunteers in red were waiting for them to turn in the papers.

"Yes." Bing Shijue hurriedly put down his schoolbag and took out the documents that should have been in it.

"No problem." The volunteer compared the information on the computer at hand, nodded to Bing Shijue, and returned the information to him, with a white card on the top.

The number written on it is the number that Bing Shijue used to have.

43。

"Once inside, you find your own room by number." The soldier next to him said, "It's going to be narrow, and there's going to be a doctor outside the observation room, and a soldier like me." ”

"Why......" Bing Shijue wanted to ask something, but he swallowed the sentence into his stomach. Silently took the information, carried the schoolbag back, put the information into it, and the white card, carefully held in his hand.

Seeing that Bing Shijue was ready, the soldier also nodded, walked up the steps, and opened the metal door. There is a smell of lubricating oil and a strong smell of metal.

Bing Shijue frowned, this feeling made him not very comfortable.

As soon as I stepped up the stairs and entered the metal gate, a dull sound sounded from behind me.

The door is closed.

"This ...... It's not pleasant. Although Bing Shijue had been prepared for a long time, a few hours ago, he was still sitting in a café leisurely, chatting with his editor about the novel. An hour ago, I was still talking to my parents in the comfort of my home.

Now, it's in a somewhat cold steel building.

As far as the eye can see, it's a very narrow corridor. In front of you is a different wall, made of soundproof glass and barbed wire. Reinforced iron doors unfolded in front of him. Some of the decaying number plates are faintly fluorescent on the top.

"Stress test?" Bing Shijue muttered to himself, "From the towering black tower, to the soldiers around the walls, and the atmosphere here, ......

"Ice Beginning 43, please come into your room, we are going to take an immunological test." A mechanically synthesized voice resounded in the passage, causing Bing Shijue to tremble. I could only raise my head, take a step, and go to find the room I was in.

The room was not far away, and as the soldiers outside had said, there was a soldier with a firearm at the door, a doctor in a protective suit, waiting for him.

"Let's go inside, because we're going to have an immunity test, so we have three levels of doors here." When he saw Bing Shijue's arrival, the doctor on the side said in a dull voice, "There are beds, tables and chairs in the room. There are also makeshift toilet cubicles, charging sockets, but no signal. ”

"And then?"

"You'll find out later." The soldier said to Bing Shijue, helping to open the metal door on the side.

In a series of intricate gear engagements, the door opens.

In the shrill friction sound, the door of the room in the shape of "Hui" was also opened.

Passing through the three doors, the room was somewhat unexpectedly gentle. Pale green, soft bed. Sofas, chairs, tables are all available. There is also a bathroom separated by a pale green curtain in the corner.

"When does the test start?" Bing Shijue walked into the room, put his schoolbag on the table, leaned back in his chair and asked.

"When everyone is there, you can do what you want until then." "I'll close the door, though." ”

"Until the end of the immunization test." The doctor picked up the words, and he came through the narrow passage on the second floor, mixing the liquid behind the translucent glass wall, "Just let me briefly introduce you to your innermost observation room. I was in the nursing room on the second floor, and the military was outside on the third floor monitoring the room. ”

"Once the immunology test starts, I'll give you a skin test through a hole in the wall." The doctor pointed to the space on the wall, "If you feel uncomfortable, press the bell in the room right away, and I will help you." If you feel vomiting, dizziness, etc., we will also see it. ”

"And if you arrange military personnel outside, is it taking into account that some people will have some violent behavior after injecting skin test drugs?" Bing Shijue asked.

"Yes." The doctor nodded, "Do you have any questions?" ”

"Yes, what happens if I fail?"

"For most people. Failure is a good thing. The doctor placed the tube on the blender, "Before leaving, you will be drawn a tube of blood and you will be paid a compensation." For the next year, I had to go to the hospital's examination department every month to have my blood drawn, and each time I had a minimum amount of local money to pay. ”

"A good thing indeed." Bing Shijue smiled, "And you don't have to take risks." ”

"yes, so it's still a little allergy, so it's better to leave here." The doctor also smiled under the translucent mask.

"Once you've passed, it's three months of picnic area exploring." The soldier on the third floor said coldly, "The mortality rate is not high now, but you won't like it." ”

"There are no jobs in the world where you can easily earn money." Bing Shijue sighed. Looked at the window on the lower wall, which opened from the doctor's location.

In other words, it's a one-way space.

"Immunization test starts fifteen minutes later, please put personnel in place."

The synthetic voice echoed again, and the doctor on the second floor waited for the mixer's countdown to end, while the military stood aside.

As for Bing Shijue, he looked at it in the room, picked up a note on the immunoassay from the table, and leisurely leaned back on the sofa and began to read.

"The person you fancy this time has a so-so mentality, so make do with it." Inside the black tower, in a surveillance room a few hundred meters away from the observation room, a middle-aged man in his fifties stared at Bing Shijue on the sofa. On the other screens, people are walking around the room in a bit of a frenzy. "However, this high-voltage test is not high-pressure enough, and a lockdown zone should be established around the city."

"Boss Ren, that's too much pressure for ordinary people. The black tower should be a symbol of hope, not a symbol of high pressure. The man who had spoken to Bing Shijue in front of the tower said, "And the situation is still unclear, if it really comes to that time, we won't be able to test them on Youzaiya." ”

"But don't let them be too optimistic...... But what you're saying is that everyone will have to go out by then. The middle-aged man nodded, "Let's wait for the test." ”

————

"Oh...... Immunoassays are done with a diluted picnic area fluid mixed with a large amount of medication. Bing Shijue looked at the contents of the single page, "This liquid has undergone a lot of animal experiments, and now it can be used on humans. ”

"If, within five minutes after the injection, the skin test area turns red and the side effects are obvious, it means that the subject's body cannot withstand the contamination of the picnic area, but there is also some kind of antibody produced in the body. At this time, the doctor will directly observe and enter the room for rescue.

After the subsidence is settled, you can go to the hospital to have your blood drawn within a year and contribute to the production of the vaccine. That's how the money comes from every month. ”

"On the other hand, if the skin test area turns blue within five minutes of the injection, it proves that the subject has neutralized the contamination in the picnic area, and can explore the picnic area, and even search for objects without wearing protective clothing."

"However, it should be noted that after neutralization, the body will enter a weak state due to the consumption of a lot of energy, at this time, please lie on the bed, press the call bell, and the doctor will come."

"If you are really weak enough to ring the bell, the doctor will be there to watch you all the time, so don't worry." Bing Shijue finished reading the single page, and the countdown was almost to the end. So he went to the soft bed and lay down, watched the rectangular wall open, and the doctor skilfully disinfected his arm.

The soldiers, on the other hand, nervously clenched the guns in their hands.

"If there's anything uncomfortable, say it right away." The doctor pushed the air out of the syringe, carefully letting the liquid drip into the trash can, and then walked to Bing Shijue's side.

"Yes."

Bing Shijue said.

The stinging of the skin being pricked, the sensation of fluid bulging under the skin is unpleasant.

However, all this is much gentler than the visual impact of the green liquid rising under the skin.

"Remember to ring the bell." After injecting a few tenths of a milliliter of fluid under the skin, the doctor withdrew his hand and locked the window.

“…… Know. Bing Shijue's gaze was firmly fixed on the greenery on his skin, waiting for the color to change.

It's a manic red.

Or is it a not-so-pleasant blue?
