He Xingchen was driven to the shelves, so he had to do what Su Tong said, sat down obediently, and honestly hacked into the Interpol system, as well as video surveillance of the road section through which Su Qing's body was transported that day.

"Officer Su, you said we wouldn't be discovered." He Xingchen couldn't help but say excitedly while tapping on the keyboard quickly.

Su Tong sat on his outstretched hand, only knocked on his head, urging him to work seriously.

In the hospital, because Lin Mei was discharged, the ward had been arranged for other patients, and Xu Sa communicated with the patient's family before taking Chen Hui and Li Hua in.

It was a single room with large windows and a great view.

Standing by the window, you can see the whole downstairs scene, just because the old building facing the hospital in the back looks a little eerie.

Chen Hui and Li Hua circled around the window, and then they turned out to take a look.

"Boss, there's nothing special about this window." Li Hua retreated and scratched his head in confusion, "It can't be that Lin Mei, hallucinating, right?" ”

"Impossible." Xu Sa replied without raising his head, and looked through the records of Lin Mei's treatment in the hospital before her death, "The case is very clear that Lin Mei has no signs of hallucinations except for neurasthenia, and the doctor's medication does not have a neurological medicine bottle, so it is impossible for her to hallucinate." ”

"However, the sixth floor is still more than twenty meters high." Chen Hui stretched out his head again and took a look, "Moreover, there is such a desolation behind this, someone appeared in the air in the middle of the night, and Lin Mei saw it alone, it wouldn't be really a hell, right?" ”

"That's right." Li Hua nodded approvingly, "If Lin Mei didn't lie or hallucinate, why did she see that thing alone?" It's impossible for our colleagues who are guarding outside not to notice it at all. ”

Xu Sa frowned, this is indeed a suspicious point, before he judged that the problem appeared on the glass and mirror, because everything was only seen by the party.

But in retrospect, in the hotel before, the victims were all alone in the room, and only they saw the picture in the mirror very normally. And Lin Mei's situation is a bit special, in addition to the colleagues who guard the door every day, there are also nurses and doctors who make rounds at night, and these people have not found any abnormalities, how did this happen?

"Excuse me......" The patient on the hospital bed stretched out his head and whispered, "Is the ghost you just mentioned floating in mid-air?" ”

Xu Sa raised his eyebrows, turned around sharply, and stared at the young man with a plaster cast on his leg, "You see?" ”

"Uh...... I don't know if it's a ......" The young man just interjected when he heard their words, but he didn't expect Xu Sa's reaction to be so big, and he was a little embarrassed for a while.

"What do you see?" Li Hua leaned over excitedly, "This handsome guy, just say what you see, whether it is for us to evaluate or not, you don't have to think so much." ”

"Yes, yes, yes!" Chen Hui nodded again and again, finally had a clue, how could they not let it go.

"Well......" the young man scratched his head and spoke slowly, "Actually, I still haven't figured out if it's my hallucination, or if I've really seen something I shouldn't see." ”

"This thing has to start from the night I was just admitted to the hospital, my leg, I was drunk at night and accidentally broke it on the road, and I came to the hospital in the middle of the night to hang up the emergency and do a bandage."

The man patted his plaster leg, a little embarrassed, "On the night I was admitted to the hospital, I was still a little drunk and my brain was not very clear, and I slept until I was in the middle of the night and I was anxious to go to the toilet." It was very dark in the room, and I slept with my head facing in that direction. ”

"At that time, as soon as I opened my eyes, I saw a person standing by the window looking at me, and I was so scared that I broke out in a cold sweat." The man pointed in the direction of the window, and lay back on the hospital bed, showing Xu Sa what kind of situation he was in at that time, "At first, I thought someone had gone to the wrong ward, but when I looked closely, it was a person, with a cloak and a face, and the most important thing was that the feet of that thing were not standing on the ground!" ”

Li Hua and Chen Hui glanced at each other, and they both shivered inexplicably, silently sighing in their hearts, it was really as mysterious as this person said.

The man patted his chest, looking frightened, "Now, I still feel scared when I think about the scene at that time." Luckily, it didn't take long for the thing to appear, and by the time I wanted to get up and call someone, it was gone. ”

"Later, I told my friends about it, and they all laughed at me for being drunk and hallucinating." The man shrugged, "So I didn't take it seriously." No, I just heard you talk about it, and I just remembered that it wasn't. ”

"Mr. Policeman, is that thing a human or a ghost?"

Xu Sa walked to the edge of the window, looked at the wide open window, and was silent for a moment, "Has this window been touched since you moved in?" ”

"It's moved!" The man nodded cheerfully, "I moved it the day after I saw it!" ”

"Do you remember what the window was like on the night you moved in?" Xu Sa closed the sliding window in the middle, "Those are open, and those are closed." ”

"Boss, what did you find?" Li Hua stepped forward and asked in a low voice.

"Well, sort of." Xu Sa nodded, "The murderer's hands and feet on the window should not have had time to clean up, we didn't find any traces, it should be the reason why the window was touched by him." ”

The killer manipulated the window to determine that the window would hallucinate in a specific way of opening......

And the reason why the patient who came in at the back only saw the appearance of a figure once was because he moved the window and destroyed the layout of the window.

"Well, I vaguely remember, but I don't know if it's right." The man gestured as he spoke.

Xu Sa asked Li Hua and Chen Hui to reopen the window according to the man's words, forming the appearance of closing in the middle and opening the corners on both sides.

"Well, yes, that's how it was that day." The man looked at it and nodded in satisfaction, "I still remember that the wind was very strong that day, but it blew in from both ends, and the sound sounded like a ghost crying wolf." ”

"Boss, what's next?" Li Hua and Chen Hui checked again and found that nothing strange appeared on the window.

Xu Sa raised his wrist and glanced at the time, and only replied with one word, "Wait." ”
