At 13:12 on January 31, in the old teaching building of Linyang No. 1 Middle School.

"It's not a good place to look at it...... No wonder you waited until I came to come in and explore. Yang Kang pushed open the door of the old teaching building, and was greeted by a stale atmosphere, dark corridors, decayed and yellowed classroom wooden doors, half-open or broken windows, broken wooden tables and broken chairs randomly placed everywhere on the ground floor and stairs, and the campus style display boards posted at the door of the classrooms, on which the announcements and photos of students eight or nine years ago were pasted in a mess.

"You think too highly of yourself, I just want to find a shield, if you really encounter any fox demons, you can go first, I will be the first to retreat." Ruyue said coldly.

"You are really ruthless when you speak, but I like your style, if you want to find a shield, you can only hide behind me." Yang Kang's face was as thick as a city wall, and he still said with a smile.

However, as soon as he stepped into this teaching building, Yang Kang smelled something was wrong, and he was immediately in no mood to joke.

After so many years of handling cases, how to describe this intuitive premonition? Yang Kang can smell this smell in the first meeting with the drug dealer, he can taste this smell in the wandering eyes of a murderer, and he can smell it under the vague prevarication of the liar's restless turn......

This smell is probably the smell of sin, a very strong, very fine, very repressed taste of original sin.

At this time, through the half-open glass and wooden windows, you can see the snow that is gradually beginning to pile up outside, the snow bends the branches outside the window, and the layers of snow melting snow along the window begin to condense into icicles.

"This old school building has six floors, and there are at least five or six classrooms on each floor, so where do we start with that?" Yang Kang had a headache when he thought of the huge space of this school, could it be that the two of them searched one classroom after another?

"Is your little brain full of mush? We still have a very clear clue, that is, the second video that captured three girls in just three seconds! It has shown us the direction of the investigation. Ruyue glanced at Yang Kang with an idiot's gaze, and threw the map of the old teaching building that she had just asked for from the security guard on an old desk.

"In just three seconds, what clues can we find from inside? Compared to these, I am still more accustomed to directly flashing guns to criminals, which is more simple and rude. Yang Kang touched the back of his head, with a "simple" smile on his face, without any consciousness that his IQ was crushed.

"Remember which direction the girl ran in the second video?" Wan Ruyue asked impatiently.

"I still have the impression that the old camera that captured them was located on the right side of the second floor of the school building, and the two girls ran away from left to right." Yang Kang thought about it and said affirmatively.

"It seems that your head has not reached the point of hopelessness, look at the map, on the right side of the camera on the second floor, there is only one music classroom, if they are fleeing from something, they can only escape from the music classroom, and the only staircase on the sixth floor of this old-fashioned teaching building is the walking staircase in the middle of the floor, if they are running for their lives, then the fastest escape route from the music classroom is the music classroom, through the camera, through the door of the 0211 and 0212 classrooms, to the stairs in the middle, Naturally, the escape was to run to the lower floor, enter the center of the first floor, then pass through classrooms 1006 and 1005, and finally run to the gate where we are currently located, probably on this route, what happened to the two girls, and never had a chance to escape from here. Wanyue said calmly and coherently, marking a clear route on the map with a pencil.

"Then let's investigate along this route first and see what we can find before making the next decision?" Yang Kangzheng said, and the mobile phone ringtone in his arms suddenly rang again, and it turned out to be the "Youth Cultivation Manual" of the dung digging boy.

Hearing the bell of this vulgar and rotten street, Ruyue wondered if it was a mistake for her to ask the man in front of her to help, and she always felt that he was sometimes reliable and upright, and sometimes he was hopelessly off the line.

"Yang Kang, where did you kid run away again? You weren't there when you were needed most! As soon as Yang Kang connected, he heard the voice of Director Xiao Quanzhi suppressing his anger.

"Wan Ruyue and I are investigating the disappearance case in Linyang No. 1 Middle School, and there are new clues recently, and I haven't had time to report to you, the director, so I have rushed to the school non-stop." Yang Kang couldn't guess who provoked the director, but he tried to be careful with his words, so as not to touch the brow of his boss.

"Grandma's, your Yang Kangzhi is well known to passers-by, saying that it is an investigation, that is, in the name of investigating the case, it is a big thing again, I am afraid that the case of your student's disappearance will have to be put aside first, now the various situations in the city are in chaos, and the army of the entire regiment of the 68th Military Region in the suburbs has been stationed in......"

What? Yang Kang had an unreal sense of disillusionment, did little Japan declare war on China or did World War III break out in Korea? Why are the armies popping up? What is happening these days is one after another to break through the limits of his endurance?

"Director Xiao, make it clear, what's going on?" Yang Kang hurriedly asked.

"Click...... rustling and rustling...... "However, there was a sudden murmur in the mobile phone, the conversation had been disconnected, Yang Kang looked down at the mobile phone again, and it was not in the service area!"

What the heck! How is it possible not to be in the service area? Even if Linyang No. 1 Middle School is not in the city center, it is also a good location next to the urban area, how can there be a place that cannot be covered by mobile phone service providers?

Just when Yang Kang was terrified, the two suddenly heard the door of the old teaching building behind them slamming the door, the large connecting reinforced frosted glass door closed by itself without warning, Yang Kang and Wanruyue could barely see a vague figure standing behind the door through the blurred glass door, the figure just glanced at them, and turned to leave.

Yang Kanghe Wanruyue hurriedly ran to the gate of the teaching building, no matter how hard he twisted the door, the door did not move at all, and it was already locked outside the door!

"Damn, why don't we ask the school worker for the keys beforehand! Now I'm locked in this hellish place! Yang Kang hammered the glass door hard, but the glass door that looked fragile was extremely strong and heavy, and he couldn't move at all no matter how he kicked and kicked it.

Yang Kang took out his pistol and looked at Wan Ruyue:

"Do you want me to give this door lock a shot and directly and forcefully open the lock? The person outside the door is very suspicious, catch him first, and our investigation of the case can go a big step forward! ”

"Wait! Get away from this door now! As soon as her words fell, the sound of something growing sounded, and countless bright red blood vessels like blood vessels grew from the glass door to the center of the door, and these blood strands jumped and spread, and it only took a few blinks to crawl all over the door......

"Bump!" Yang Kang did not hesitate to pull down the safety, and one shot hit the location of the glass door lock, but the bullet only made a small wound on the flesh wall composed of bloodshot that wrapped the door lock, dripping a few drops of black blood, and then countless bloodshot then began to repair the wound, and after a while, the bullet was squeezed out of the flesh by the growing blood and fell to the ground.

The bullets of the pistol had no effect on the fleshy gate made of red blood.

And almost at the same time, all the windows and doors that could see or lead to the outside world on this first floor began to grow such a layer of flesh, completely isolating this first layer from the outside world! The outside light was blocked by this eerie layer of flesh, and the room became darker and darker, until at last it was almost completely invisible to the outside light shining through the windows......

"Are we forcibly locked here by this rotten meat?" Wan Ruyue asked uneasily, she raised her phone and turned it on as a flashlight, barely illuminating the space around the two of them.

Yang Kang was about to answer, but he heard a sharp and low voice echoing in the empty floor......

"Twitter, twitter......" sounded again and again, poignant and melodious.

That's the fox chuckling!
