The voice came from overhead, and Xiao Ning immediately understood. The reason why men are not afraid of being found is because the room they are in now is not in the open at all, but in the dark. That is, he is now underground.

The man's somewhat distorted facial features gradually returned to normal, and his eyes were like a poisonous snake, staring coldly and fiercely at the ceiling above his head.

The light bulb had just fluttered twice with the sound, but now it was no longer shaking.

Xiao Ning thought of Yin Zetai, could it be them on top?

But after a long time, I didn't hear a sound.

The man looked at Xiao Ning with a smile, "Aren't you disappointed?" I guess the security guards came to patrol, and I occasionally encounter such things. But if you're smart enough to save some effort, otherwise no one will be able to hear you even if you shouted for help just now. Here, I took a lot of effort to renovate it, which is not only soundproof, but also very hidden. Officer Xiao, don't think about running away, obediently become a part of my great work. ”

Xiao Ning had already grasped his weakness and knew how to stall for time.

He smiled, "It's really condescending to let you be a political teacher, you should be a great scientist and contribute more to the progress of mankind." Otherwise, if you are alone, your achievements will be limited after all. The state has better instruments, more money, and more human bodies for you to use. ”

The man's expression became a little lonely, "I haven't thought about it, but this country is pedantic, and so are those so-called scientists." They won't approve of my experiments, and I can still make results on my own. ”

"By the way, I have one more thing I have to tell you."

Xiao Ning said: "Since you want me to be the spinal cord of your great work, at least, you should also give me a physical examination, right?" I'm not afraid to tell you, I'm not in good health, and I think you can see it. ”

He was born with pale skin, but now he has solved cases one after another, and the sides of his cheeks are somewhat sunken due to fatigue, and the dark circles under his eyes are very obvious due to the poor sleep for many years.

Together, this kind of person makes him look less energetic than a young man, but a little more gloomy.

The man was reminded by him, and nodded suddenly in realization, "That's right, you're right, my work can't have any flaws, I want to make sure you're healthy." ”

He pulled the syringe from the tool table next to him, "Give me a little of your blood." ”

In the penultimate storage room on the first floor of the experimental building, Yin Zetai reached out and took out a little tape left in the cabinet and looked at it carefully.

Xu Xingteng asked in a low voice, "Did the boss be tied up here before?" ”

Yin Zetai shook his head and pointed to a slender black line on the tape at the same time, "This length should be a woman's hair." If there was a woman who was tied up here before, it is very likely that the boss found out and was taken away by the murderer. ”

Li Ke, who was looking around at the storage room, suddenly exclaimed, "Look here! ”

He was referring to the leg of a stool in the corner, the kind on a normal desk, painted with yellow logs, on which the blood stained could be seen at a glance.

Xu Xingteng swallowed his saliva, "Could it be the boss......

"Shut up!" Yin Zetai took a deep breath and tried his best to calm down, "Whether the boss is victimized or not, he must still be in this building, we have already seen the surveillance, and we have not found him going out." ”

Li Ke muttered in a low voice, "But we've all looked for it here......"

"No...... It must still be in this building. Whether it's a woman who is tied up, or the boss, they are all adults, and it is unrealistic to want to take them to a far place. And there is also a night vision monitor near the school playground, and I haven't gone out since the boss came in. Since there is no one on the surface, it must be in secret. ”

With that, his eyes scanned the surroundings, trying to find something out of the ordinary.

Xu Xingteng joined in, "Maybe it's some basement or something." ”

His words made Yin Zetai wake up suddenly, and he immediately stomped his foot heavily.

A hollow sound came, and he and Xu Xingteng looked at each other, and said almost at the same time: "It's empty below!" ”

Generally, as a school building, for the safety of students, whether it is in building materials, or in foundation and construction, there is no need to cut corners.

Otherwise, in the event of an accident, it will not be one or two people who will die, but many.

What's more, when it comes to places like students and schools, public opinion in society will immediately ferment.

Even those construction companies don't dare to take kickbacks, and all materials must be used well.

And this foundation is absolutely impossible to have a hollow situation.

In this way, there is only a human possibility.

And here, Yin Zetai found that there was a tape of women's hair, which was very sticky and there was no dust, which was obviously left over in the past two days.

And the blood stains on the legs of the table did not all dry up, which was in line with Xiao Ning's time here.

Everything points to the fact that the murderer is here, and there is something wrong underground.

Yin Zetai's hand was on his lips, "Be quiet, if there is someone below, you must have heard the sound of us stomping our feet just now." Don't startle the snake, or it will likely make the boss more dangerous. ”

Xu Xingteng was also a little anxious, "Then what should I do now?" ”

Li Ke said: "What else can I do, of course, is to find the entrance." But wherever there is a basement, there must be an entrance. Only by finding the entrance can we enter without us noticing. ”

By now, it's too late. It is impossible for Yin Zetai to find someone to dig up this place, otherwise it is likely to cause a collapse, and the only way, as Li Ke said, can only find the entrance.

Fortunately, the members of the criminal police brigade who had requested support had arrived, and a group of people lowered the volume as much as possible and began to look for the entrance to the basement.

Zhou Qing stood outside the laboratory building smoking a cigarette, praying in his heart that Xiao Ning would be fine.

Footsteps sounded behind him, and when he turned around, he saw Yin Zetai, and immediately frowned, "Next time there is such a thing, you must come with you, don't let him risk himself again." ”

Yin Zetai smiled bitterly, "I want to follow too, but if he doesn't tell me in advance, I can't stay with him twenty-four hours a day." ”

Zhou Qing sighed, Yin Zetai couldn't be blamed for this matter, he continued to ask, "Did you find the entrance?" ”

"Still looking, but it should be soon."

After saying that, Yin Zetai turned around and went back and continued to look for the entrance.

Zhou Qing finished smoking this cigarette and returned to the storage room.

After half an hour, one of the officers finally noticed that something was wrong, and he exclaimed in a low voice, "I seem to have found the entrance!" ”
