As the night falls, space advertisements are colorful and all kinds of special effects are constantly playing.

In the northwest corner of Changfang District, the low hills are undulating, breeding vigorous vegetation.

In the dense greenery, buildings rise from time to time.

One of the tall buildings, at a significant distance from the others, sits alone in a mountain col.

It is about fifty or sixty stories high, and the exterior is still hung with broken scaffolding, as well as some abandoned cranes, etc., and it is obviously a ruined building.

The baffles around the building have long existed in name only, and there are breaches everywhere.

More than 40 years ago, the richest man in Binhai City invested 10 billion yuan to build a top luxury entertainment venue, for which he specially invited the international first-line designer to design, and the draft was flying all over the sky when the construction started, and everyone thought that after a few years, Binhai City would have a new landmark.

But unexpectedly, within a few years of the start of construction, it encountered a "digital rain", the world situation changed greatly, the richest man went bankrupt, and the "Huangjia Club" was declared unfinished after several financing failures.

At the beginning, there were often anchors and the like who came to shoot and explore, but there were countless buildings with similar encounters, and with the passage of time and the remoteness of the "Huangjia Club", gradually, it disappeared in the memory of most people, and it was corroded and forgotten alone in this mountain col.

A black business van, under the cover of night, drove into the building very easily.

The interior is spacious without doors and windows, any decorations, and the sound of the car's engine echoes.

The headlights illuminated the scene ahead, and rows of load-bearing pillars stood silently, and between the pillars were large open spaces, extending into the distance where the headlights could not shine. In the field of vision, in addition to dust, mud and some construction debris, the entire building has been silently eroded by plants, the ceiling is crawling with all kinds of vines, clumps of grass blades emerge from the cracks of reinforced concrete, and moss mottled growth in the shadows.

The development of science and technology and the great power of nature are intertwined and entangled at this moment, which is both contradictory and integrated.

The vehicle stopped in an open space, the main and co-pilot doors opened at the same time, and Zhou Zhen and Xie Qiongning stepped out of the car.

Xie Qiongning looked around, and soon found an inconspicuous luminous mark, pointing deeper.

She motioned for Zhou Zhen to follow.

Before the two of them could follow the marker for some distance, an electronic door appeared in front of them.

Xie Qiongning took out an invitation letter and shook it in front of the sensor in front of the door, and the door opened immediately.

As soon as they walked in, the electronic door closed.

Behind the door is a small blank hall, and at intervals on the wall, hangs a hand-held flashlight, which winds like a street lamp deeper into the basement of the unfinished building, attracting many flying insects to circle and chase after them.

The dim light illuminated two old doll costumes on the ground, one for a duck and one for a cheetah.

This kind of doll costume is fully enveloped, and people can't even tell whether they are male or female, tall or short inside.

Xie Qiongning casually picked up the cheetah's doll costume and explained, "These are all disposable prop costumes. ”

"Many of the people who come to participate in the transaction are sensitive and cannot be seen."

"So, the organizers will arrange different entrances for all the people who come to participate in the transaction."

"At each entrance, this kind of prop costume will be prepared in advance."

"It's a modification of the doll costume that the merchant uses to solicit business, and there is a voice changer in it, which randomly generates a sound tone, and after changing it, it is difficult for others to recognize it. There is also a self-destruct system, which will automatically destroy it about 10 minutes after taking it off to avoid leaving biological information behind. ”

"Of course, the organizers themselves are the same."

Saying that, Xie Qiongning checked the prop costume and made sure that there was no problem, and quickly put on the doll costume.

This cheetah's doll costume is very heavy, and even when worn over the original clothes, it looks extremely loose.

Xie Qiongning put on the hood and gloves again, and he couldn't see the original appearance at all.

Zhou Zhen nodded, picked up the remaining duck doll costume, and put it on his body.

After making all the preparations, Xie Qiongning followed the instructions of the "street lamp" and walked forward, followed by Zhou Zhen.

Step, step, step......

The monotonous sound of footsteps constantly echoed in the dim space, and from time to time, a puff of dust was stirred up and repeatedly flown up.

At the beginning of the construction of this building, it was intended to operate the top club in Changfang District, and the planning was very thoughtful, even if it was not completed halfway, it was extraordinarily vast, a bit like a large karst cave.

The two of them followed the "street lamp" several times, descended a flight of stairs in the middle, and continued to walk in this labyrinthine building, no longer knowing the direction clearly, only vaguely feeling that they were walking towards the center of the building.

As he walked, Zhou Zhen suddenly asked: "This place, it looks like it has been abandoned for a long time, these flashlights, as well as the electronic door just now, seem to have been installed on a private site." ”

"The previous trading places were all like this?"

Xie Qiongning said: "The location of each transaction is different, I didn't go to the last transaction, and I don't know what it looks like." ”

"This organizer often makes all kinds of requests for no reason."

"For example, change the place of trading."

"Or like this time, change the trading hours......"

"Also, there is a rumor, I don't know if it's true......"

"Some of the people who have completed the transaction with this organizer will always have various accidents and high mortality rates for some time after that......"

Accidentally?

Death?

Zhou Zhen frowned, and was about to ask a little more detailed, when the front suddenly opened up, and a hand-held flashlight illuminated a very wide hall!

This hall was supposed to be at the intersection of the circulation lines, and in addition to the one they came out of, it connected a dozen other similar corridors.

And inside these corridors, there seem to be more forks in the road.

The flashlight emitted a dim glow, illuminating only a small area of the rough hall, most of which remained hidden in the darkness.

Beneath a load-bearing column, an old-fashioned round clock is thrown, and the hour and minute hands show the time at exactly 22:55.

At this moment, not far from the round clock, there are already more than a dozen figures wearing doll costumes, including big bad wolves, golden monkeys, peacocks, white apes, huskies, cheese cats, and big white geese......

All the figures were very quiet, and occasionally someone raised their hands to repel the moths that flew in front of them, and there was no communication between them.

Zhou Zhen and Xie Qiongning immediately stopped talking, and the two walked to the crowd and stood not far away, also without saying hello to others.

Zhou Zhen secretly observed these people who arrived first, they were basically in groups of twos and twos, keeping a certain distance from each other, and were divided into nine groups in total, counting him and Xie Qiongning, ten groups of people, ten invitations, and five people with invitations were not present.

In addition, the organizers of the trade fair have not yet appeared......

Moaning slightly, Zhou Zhen continued to wait silently.

It didn't take long for two groups of people wearing doll costumes to come out of the two opposite corridors.

After another moment, two groups of people came in the front and back feet.

The second hand was ticking and ticking, and when the minute hand pointed to 22:59, the two people with the last invitation also rushed over.

Fifteen people with invitations have all arrived.

Everyone waited in silence, without any communication.

Finally, at 23:00, a figure dressed in a frog doll costume walked in through one of the corridors.

The figure walked to the front of the crowd with a wooden box in his hand, stood still, and said in a somewhat hoarse voice: "Everyone, old rules, let's start!" ”

As he spoke, he put down the wooden box and opened it, and inside were all kinds of mathematics textbooks, mathematics exercise books, mathematics test papers, and mathematics books......

The "frog" took out all the math textbooks from the box and set up a total of three stalls in the open space in front of him like a stall.

Seeing these math textbooks, the people around immediately surrounded them.

Zhou Zhen also followed the crowd and quickly approached the "frog".

"Frog" said in a hoarse voice: "The transaction time is still 3 minutes, and the payment time is 2 minutes. ”

"Now the lights around are yellow, and after 3 minutes, they will turn blue, so when the time comes, hurry up and pay the money."

"After 5 minutes, the lights turn red and the deal closes immediately!"

"This batch of math textbooks is from the first to the third year of high school."

"Don't blame me for not warning in advance, the high school textbooks from twenty years ago have a high risk of infection!"

"Of course, the possibility of becoming a compatible person will also be higher!"

"This time, the price is a little higher than before."

"The textbook of the first year of high school, a whole set is 100 'Poda coins'."

"The second year of high school is 200 'Podas', and the third year of high school is 300 'Podas'......"

Just when the "frog" was quoting, Zhou Zhen had already taken the opportunity to select teaching materials and walked not far in front of the other party step by step.

This position, immediately close to the distance he can shoot!

But at this moment, the "frog" suddenly walked towards a buyer wearing a big white goose doll costume, and covered a half-turned math textbook from the other party: "Don't you understand the rules?" ”

"The math textbooks here can only be bought, not read!"

"If you don't want to buy it, you can not buy it!"
