After Li Hejun left, we didn't speak, Nangong Yi replayed the video that Qiao Kewei left in the phone, in the end of the picture, a light appeared in front, Qiao Kewei from the last person, she shot from the angle of the person who walked at the end, just enough for us to see the steps that Li Hejun mentioned to us.

Count down from the video.

One two three...... Sixteen Hundred Seventy Eighteen ......

My fingers stopped on the last step, dumbfounded and staring at the others.

Nineteen!

In the video screen, there are no more, no less, just nineteen floors!

The light that appeared in front of it was particularly eye-catching in the dark night, and Li Hejun told us that if the nineteenth floor of the lowest steps of the building appeared in rumors, the passage to the underworld would be opened!

I recalled what Liang Huiyin said in the video.

You don't belong here, come with us......

Could it be that Nie Bingwan didn't know that she was dead, and she still refused to leave, and Liang Hui was in the underworld because the place they wanted to take Nie Bingwan to was the underworld?!

After watching the video, all of us were shocked, and hurriedly rushed to the No. 19 building, Nangong Yi was afraid that the clues would be destroyed, so she had already ordered Wen Jinnan to temporarily block the building, and we walked to the steps leading to the basement.

Step by step, I silently counted in my mind every step I took, until I reached the last step, the number in my mind stopped at eighteen, I looked back at the other people behind me, and when they finished walking, I knew without asking their expressions.

They're just like me, and it's only eighteen floors!

But we clearly counted the nineteenth step in the video shot by Qiao Kewei, why are there only eighteen in front of us?

I squatted at the last layer of steps to carefully investigate the surrounding joints, Nangong Yi also sent someone to conduct a comprehensive inspection here, and the final conclusion made us all a little dazed, under the eighteenth layer of steps is a solid cement structure, and there is no gap around the tight seams, the rumored extra nineteenth layer of steps is impossible.

"After all, it's just a rumor, and the facts prove everything, and from the results of the investigation, this rumor has been self-defeating." Nangong Yi said.

"But why is there a nineteenth staircase in the video?" The prince also asked with some doubts.

"The video was shot at night, and Qiao Kewei was coerced at that time, so the picture shook badly, probably because of a visual misunderstanding that caused us to see clearly in the picture, so we counted the nineteenth step." Yun Duruo thought for a moment and answered.

Although we have more or less reservations about Yun Duruo's explanation, the factual results do not allow us to question anything.

"Light! How to explain the appearance of light? Han Yu stood up from the ground and asked seriously. At the end of the video, there is a very bright light, it seems that some door is opened, even if we count the wrong steps, but how did this light come about? ”

Han Yu's words made me react too, I looked around and found that the steps lead to the basement, but the place where the steps end is a wall, and this wall has been investigated before, it is a solid load-bearing wall, which excludes the possibility that there is something in the wall.

The light in the video could not have come from the wall, and my eyes fell on a nearby iron door with a heavy iron lock hanging from it, and the iron door was rusted in many places, presumably for many years.

"What's in this door?" I asked the person who brought us down.

The man shook his head without saying a word, and I looked down to find that he was clearly holding the key in his hand, and when I saw me staring at the key, the man subconsciously put the key behind him.

"You're holding the key to this iron door?" Yun Duruo asked in an accentuated voice.

The man still shook his head and said nothing, his eyes looked behind us, and when he turned around, he realized that he was looking at Li Hejun, and suddenly found that this person had not spoken since he brought us down, but he looked quite familiar, as if he had seen him somewhere.

After thinking about it for a long time, I remembered that I saw this person on the roof of the building when Qiao Kewei jumped off the building, and all the teachers present at that time tried their best to persuade Qiao Kewei to come down, as if this person was standing on the roof of the building without saying a word then, as he is now.

I turned my head to look at him again, and when I came down I noticed that he was walking with a slight limp, probably caused by a leg disease, this man was in his fifties, and his hair was mostly white and uneven mixed with the few black hairs, which made him look even older, and every wrinkle on his face was very deep, but his eyes were particularly bright.

"Oh, his name is Wen Jike, don't ask him, he won't answer, he's dumb." Li Hejun behind him said to us.

It turned out to be a mute no wonder he didn t say a word all the time my eyes were still fixed on the key hidden behind him in wen jike's hand and looked back at li hejun and asked.

"What's inside this iron door, is the key to this iron door in his hand?"

"He's the caretaker of this building." Li Hejun nodded and said helplessly. "The key in his hand can indeed open this iron gate, but this is a forbidden area for Hede Medical College, and no one is allowed to enter without permission from the dean."

"Forbidden Zone?!" Yun Duruo pursed his lips for a long time before he said in surprise. "Is there any place in this medical school that is forbidden, not to mention that there are five lives now, what else can't be checked? Now it's time to investigate the case, and people's lives are at stake! Hurry up and open the iron door! ”

Li Hejun and Wen Jike looked at each other in embarrassment, and I suddenly realized a problem, not what was behind the iron gate, but the dean Li Hejun just mentioned, there were five murders in Hede Medical College in a row, but until now we have never seen the top person in charge of this school, and this dean is really calm enough.

"Open the door for them."

The voice came from behind us, looking back at the steps, a middle-aged woman in her fifties walked down to us steadily, her voice was serious and low, from my point of view, it happened to be facing the sun, so I couldn't see her face clearly, but from this woman's voice and steps, it was not difficult to see that this should be a very majestic person, Wen Jike, who had insisted on refusing to take out the key before, immediately opened the iron door without saying a word.

Only the dean of Hede Medical College has the right to open this iron door, and there is no need to guess that this woman who is walking towards us should be the dean.

Until she stood in front of us, Nangong Yi and Yun Duruo were girls, and they all screamed in horror the moment they saw her face, even Han Yu and I were secretly startled in our hearts, only the prince was really calm and unmoved.

The woman who walked in front of us was capable and neat, giving people the feeling of not letting her eyebrows go, her gestures were calm and sophisticated, and her eyes seemed to be able to easily see through what a person was thinking, but her face was ......

Maybe it can't be called a face at all, the scar that has already healed is covered on it, presumably it has suffered a very serious trauma before that caused disfigurement, the scar is dry and curly, it is easy to tell that this is a trace of being burned by the fire, and most of the whole face is full of holes, giving people a hideous and terrifying feeling.

But this woman does not have the slightest intention of covering, looking at our straight waist, if this face is plastic surgery repair, although it can not be restored to its original appearance, but it will definitely not be as scary as now, from the scars these scars should have been left many years ago, for a woman whether the face is exquisite is a big deal, but this woman doesn't seem to mind others to see her current appearance, but she can look at us without a little inferiority, which shows how confident this woman is.

"This is our Dean Jiang." Li Hejun, who was standing next to us, introduced us with a respectful attitude.

"My name is Jiang Xinyu, and I am the dean of Hede Medical College, and I locked this iron door." Jiang Xinyu looked at us very seriously and said. "If it is helpful to investigate the case, I am willing to cooperate with you."

After Jiang Xinyu finished speaking, he motioned to Wen Jike to open the door, and when the heavy iron door was opened, the noise and creepy laughter mixed together came out from inside.

We were very puzzled and walked in behind Jiang Xinyu, and found that inside the iron door was actually a prison-like place, which was divided into rooms of different sizes, each room was separated by two glass doors, and everything in the room could be seen at a glance from the outside. Transcript:

In each room there was a person locked up, all dressed in loose clothes, some even with bags tied with their hands tied and only one head exposed, all of whom were strangely expressiond, but mostly dull and stared.

Maybe it's because of someone's appearance, many of the people who were locked up became very excited, behaving strangely on the glass, and their hands kept scratching up and down, as if they wanted to break free from it, and their mouths made strange screams or frightening smirks, and I saw that there were still people banging their heads against the heavy glass, and the heavy impact made this room blocked by iron doors even more terrifying and cold.

"This ...... What is this place? Yun Duruo asked after looking around in shock. Why are these people locked up? ”

"The predecessor of Hede Medical College was the Institute of Psychiatry, which is actually what ordinary people call a psychiatric hospital." Jiang Xinyu said as he took out a baton from Wen Jike's waist, and tapped it on the iron fence next to him a few times majestically, and the noisy room suddenly quieted down, these people didn't know whether they were afraid of the baton or Jiang Xinyu, and they all quietly retreated to the corners of various rooms. "This building used to be the treatment ward of a psychiatric hospital, and it is now, and the building you saw on the outside is now filled with people with various degrees of mental illness."

"That'...... So why are these people locked up here? I asked, frowning in surprise.

"It's not about locking them up, the people in every room here are mentally ill, but unlike the upstairs, these people are very aggressive patients with antisocial personalities." Jiang Xinyu handed back the baton in his hand to Wen Jike and answered us unhurriedly. "These people can't be put with other patients, because they don't know what they will do, so they can only be held in solitary confinement with the highest security, and many of them are extremely vicious murderers, but after being caught and convicted, they will be sent here if they are found to be seriously mentally ill and cannot be admitted to prison!"
