"I'll call Fang Ling, and then you and Flora will go to the doorman to get the communication equipment and luggage, and after you get it, go down, and listen to Fang Ling's command on the way."

"Who is Fang Ling?"

"The analysis department is dedicated to studying your abilities, and then he's the one you're going to work with."

Su Ming called Flora and went to the doorman to get her luggage and communication equipment, the luggage was a very heavy backpack, the backpack was filled with compressed biscuits and water, and many batteries.

In addition to this, they were given a communication device and a flashlight, as well as a wristband.

"We're going to that basement?" Flora.

"Yes." Su Ming nodded and looked at Xia Xiaoyu, "They didn't prepare your luggage, do you want to go and buy it temporarily?" ”

Xia Xiaoyu patted the No. 7 storage box behind him and replied, "It's enough." ”

Su Ming put on the communication equipment and connected to Fang Ling's call line, and as soon as he connected it, a gentle voice came from the opposite side.

"Hello, I'm Fang Ling, and I'll assist you in completing this test.

The device you're wearing on your head now has not only a phone call, but also a photography function, so I can see what's right in front of you.

And the bracelet on your hand will collect your heart rate and body temperature, and I will monitor your body through this data to make sure you are healthy.

Now, it's time to head out to the basement. ”

Su Ming: "Understood. ”

With everything ready, Su Ming and the three of them set off towards the spiral staircase in the basement.

He re-entered the basement, opened the innermost door, and entered the stairwell.

As soon as he stepped into the stairwell, he felt the temperature around him drop a bit.

Su Ming began to observe the situation inside, and in front of him was a spiraling staircase, with a concrete floor under his feet, and the railing was an unpretentious stainless steel pipe, inserted into the steps in a cross shape, welded together.

Su Ming took the flashlight, walked to the edge of the railing, and shone it down, the light of the flashlight did not pierce the darkness, the light even shot out a meter away, and the excess light seemed to be absorbed by this darkness.

"No matter how powerful the lighting is, it can only illuminate the distance around it one meter away, which is the characteristic of this staircase." Fang Ling in the headset said.

"Su Ming, did you hear that voice?" Flora, who was next to her, asked softly.

Su Ming: "What sound?" ”

"Like...... It's a girl's voice. Flora said.

Su Ming looked at Xia Xiaoyu next to him, and Xia Xiaoyu also nodded: "Although it's very slight, I also heard a little." ”

Fang Ling in the headset spoke again: "Normal phenomenon, let's go down." ”

"It feels weird here." Su Ming said as he walked down.

"It's a weird staircase, but it's not dangerous, as long as you don't mess around, it's generally not life-threatening." Fang Ling said.

Su Ming paused, his brows furrowed: "In other words, there will be danger to your life if you mess up?" ”

"You can understand that, but I'm sure you'll both be safe in the end."

"I don't accept this kind of ambiguity, can you reveal more?"

"It's not a secret, in fact, it could be compiled into an informal file, but there are people on it who are afraid of affecting the subject's spirit, so it ends up being put in the analysis department's file.

To put it simply, you will face the test of fear later, and when you face your fear, many people will be confused, and many ordinary people will jump over the railing in a panic.

Of course, you're not ordinary people, so don't worry too much, as long as you're not stupid enough to jump off a building, you'll be fine. ”

"The people who jumped fell to their deaths?"

"They should all be dead, but it's possible to be alive, after all, this place is a different dimension. No one has ever reached the bottom, and if you get to the bottom, you can help us find out how many people have died down there...... Haha, just kidding. ”

"When I first heard the voice, I thought you were a normal person." Su Ming said.

Fang Ling: "Huh? Isn't it? I'm a normal person. ”

"Psychopaths always say they're not mentally ill."

"It's rude, you're the first person to say that about me."

Su Ming didn't respond to the other party again, he walked down intently, the light of the flashlight could only illuminate the three steps under his feet, and the farther place was immersed in darkness.

No matter how many steps they took forward, it was the same scenery, and the sound became extremely clear in the silence, but there was no echo in the vast space.

After walking for an unknown amount of time, Su Ming felt a little tired, so he stopped.

"Hungry?" Su Ming asked.

"Hungry." Xia Xiaoyu said.

"Flora, are you hungry?" Su Ming asked again.

Flora nodded slightly: "One point, let's take a break." ”

"Well, eat something and go."

Su Ming sat down on the steps, took out compressed biscuits from his backpack, mixed them with dried water, and asked while eating, "How long have we been walking?" ”

"Three hours." Fang Ling replied.

"Three hours...... That should be a long way out, right? ”

"It's a long way off, but we generally use the term depth to describe the depth of the subject in the spiral staircase. Let's say Flora is now 30 meters underground, and you are 1 meter underground. ”

Su Ming was stunned for a moment, and suddenly turned his head to look at Flora, who also stared at him in surprise.

"But Su Ming is right next to me, and the two of us are together." Flora said.

"Yes, but the instrument shows that you are not at the same depth."

“…… So why are we in the same position now? Could it be that Su Ming beside me is just a phantom? ”

Flora touched Su Ming's arm, and she could touch it.

"But I can touch him."

Fang Ling: "Flora, just now, you moved another meter down. ”

"What's going on?" Flora was taken aback.

"Haven't you watched the online class? What is the first rule of thumb for dealing with weirdness? Fang Ling asked.

"Don't cling to common sense, accept reality, and look for patterns." Su Ming answered Fang Ling's question in place of Flora.

When he first heard this, he didn't quite understand it, but now he gradually understands it a little.

There is no logic to this kind of thing, just like now, she and Flora have taken exactly the same number of steps, but the measured depth is different.

The difference in depth means that the position is different, but he can have physical contact with Flora, which is very strange.

This place is dedicated to measuring the limits of human fear, so can it be understood that the depth of this space is the degree of fear in the human heart?
