Before eight o'clock, Shen Xing arrived at the gate of Yungu Vocational College as promised.
Li Naijing and Zhao Wenbo's cars were parked next to the college gate. They had just gotten out of the car and were packing their backpacks.
Shen Xing was slightly startled when he saw how they were dressed. He didn't expect that he and they were all thinking about the same thing. Even the equipment and backpacks were similar.
However, Li Naijing and Zhao Wenbo were here last time, and they must be doing this now based on their last encounter. There is a reason for this.
After Shen Xing approached, Li Naijing looked at the backpack on his body, nodded and said, "Yes, it seems that you have prepared it in advance. I also left a set of tools for you."
As he spoke, he pursed his lips towards the back seat of the car.
Shen Xing looked down and saw that there was a black backpack inside, which was obviously prepared for him.
Opening this backpack, the contents of the bag are similar, but it seems that the quality of the backpack and the tools inside are better.
He immediately exchanged the items he needed in his bag with this backpack and put it on his back, which was a black backpack specially designed for the investigation team.
He noticed that the backpack had a six-pointed star logo printed on it, which was the exclusive logo of the special case investigation team.
After Shen Xing changed it, Li Naijing handed him a work ID, which was the temporary case handling certificate of the investigation team. It was a palm-sized hard-shell card, dark black with gold fonts, and was valid for three years.
Shen Xing took a closer look and found that it was not much different from Li Naijing's regular Sheriff's ID. It also had a six-pointed star logo, but it didn't have Li Naijing's Sheriff's ID holster, so it looked a little less classy.
Then Li Naijing handed over another bank card.
"This is your reward card. The initial password is six zeros. If you help us handle cases in the future, you will be paid on a per-piece basis. This time it is three thousand yuan. After the case is completed, the money will be transferred to this card within five days."
"Thank you!" Shen Xing took the bank card.
It would be different if he was paid. At least he should be more attentive when doing things. Who would let life weigh him down?
"The thing is like this." Zhao Wenbo introduced from the side: "There was a haunting record in the basement of the auxiliary building of the library of this vocational college ten years ago. At that time, Brother Zheng came to investigate, but there was no result. Later seven There was another documented haunting two years ago, and then two years ago. Well, people were said to have died two years ago, but it was suppressed by the city hall and the college.”
"Then what's going on now?" Shen Xing asked.
Li Naijing took over and said: "A librarian reported to the school last week that he could hear some strange sounds coming from behind the door of the basement of the auxiliary building almost every day in the past two days. Later, the school organized security to go and check, but who knew that three people were there? Security guards came up and said they had hit a ghost."
"Were you here when I called you?" Shen Xing asked curiously.
"Yes." Li Naijing nodded, "At that time, Zhao Wenbo and I were on the stairs in the basement. We kept walking down, but we couldn't reach the end and kept going down the stairs. Later, we felt something was wrong and looked around on that floor and found some very interesting things. Strange phenomenon, but no real anomaly found.”
After a pause, he added: "Later, we wanted to leave, but we couldn't get out. No matter what, we were wandering around on the second floor below, and something bad was happening. At this time, you called, and It happened that the mobile phone had signal, and after I answered your call, I found that the elevator suddenly became normal, so I quickly ran upstairs."
The three of them were talking and walking towards the academy.
Shen Xing said thoughtfully: "The situation you said you encountered is a bit like the Penrose Stairs, also called the Impossible Stairs. That staircase is like a ladder that always goes up or down, but never ends. .”
Li Naijing and Zhao Wenbo were stunned for a moment, and asked in unison: "Who is Penrose? Is your surname Peng? This name is very strange."
Shen Xing knew that there were no foreigners' names in this world, so he didn't bother to explain: "Just pay attention to what I described. The staircase you may encounter is the staircase that never ends."
"It will never end?" Zhao Wenbo repeated.
Shen Xing originally wanted to talk about "Moebius Strip" and "Klein Bottle", but these two are foreign names and would have to be explained later, so after thinking about it, he forgot it.
The three of them had an unobstructed journey. Because it was almost time for evening self-study, there were not many students on the way. These students just looked at them a few more times after seeing them.
The school security guards had already been greeted by the school, and no one stopped them.
Soon I arrived at the library, and after approaching the annex building, I saw the sheriff and a security guard who were on duty here looking a little frightened, staring at the small iron door that was sealed.
"What are you doing?" Li Naijing asked.
The sheriff pointed to the iron door and said, "There were calls for help from inside just now. Someone else was banging on the door, but we didn't open it."
"It can be opened now." Zhao Wenbo instructed.
Because there is a light above the top of this small iron door, even though it is dark now, once the door is opened, this area can still be seen clearly.
The security guard quickly took out the key and opened the door. The moment he opened the door, he immediately took a few steps back, almost behind Shen Xing and others.
The light can shine into about two or three meters inside the door. Because the stairwell extends downward, any further distance will be plunged into darkness and nothing can be seen.
Everyone looked carefully. Among them, Shen Xing, Li Naijing and Zhao Wenbo were closer, while the ordinary police officers and security guards were further away.
There was nothing at the door.
"Are you sure you heard someone calling for help just now?" Li Naijing turned around and asked.
"OK." The security guard and the sheriff nodded.
"There may be something abnormal inside that is causing trouble." Zhao Wenbo whispered.
Li Naijing nodded and ordered: "Now we act according to the plan. All three of us cannot go in. Shen Xing is a novice. Zhao Wenbo and I will go in first. If something goes wrong or we need your help, we will contact you. If we can't When you run out, you will be prompted to the outside through the string, so just pay attention to the feedback."
After saying that, she and Zhao Wenbo took out a string from their backpacks and demonstrated the signal to pull the string again.
I don’t know what kind of material this string is made of. It is not only slender, but also strong and tight. After being tightened, it will not break even if it is cut with a steel knife two or three times.
The string is very long after being pulled open. One end can be fixed somewhere, and the other end is like a belt that can be tied to the explorer's waist so that the explorer can be pulled out after entering a certain area.
Li Naijing and Zhao Wenbo tied their waists with belts respectively. Shen Xing fixed the other ends of their strings on the railing of the flower bed not far away and pulled it twice. It felt very strong.
Li Naijing told Shen Xing: "Tie a string around your waist and be ready. Zhao Wenbo and I will go down now."
After saying this, she and Zhao Wenbo walked into the open small iron door one after another, walked down the stairs, and quickly disappeared into the darkness.
Shen Xing still remembered what Li Naijing said that all the lights in the area under the stairs were not working. It was unknown whether they were broken or due to abnormal interference, so they could only use flashlights for lighting.
After Li Naijing and the others entered, he also tied up the strings on his body. Together with the ordinary police officer and the security guard, they stared at the two thick bundles of strings on the ground. After Li Naijing and the two entered the small iron gate, they were constantly being beaten. Pull in.
