It is not uncommon for underground spaces to appear in modern architecture.

With the development of various technologies, people are making more and more use of underground space.

Especially in the central area of the city, looking at the urban underground, it seems that it has been widely developed, with underground shopping malls, subways, underground passages, and underground garages......

As soon as Old Master Qin mentioned that there were people underground, Qin Xu immediately began to think, where would the intersection into this underground space be?

The underground space is very hidden.

Surrounded by a thick layer of soil, the sound insulation effect is far better than that of the ground building, and at the same time, the ground on which the feet step becomes its best shelter.

There may only be a large space for the manhole cover of the sewer pipe, which is the intersection between the underground and the ground.

Old Master Qin heard someone crying underground, indicating that someone inside was being punished.

Qin Xu asked Old Master Qin to determine the approximate scope of the small dark house underground a little bit through the echo of the cry in the space.

The small black house underground, just under Qin Xu's feet, happened to be within the ability of Old Master Qin.

However, when Old Master Qin was exploring, he stated in advance that in the past month, there was a time limit for the help he could provide to Qin Xu every day, and he needed to use more energy from the Divine Beast White Bone to restore his physical strength.

Qin Xu walked out of the toilet cubicle, washed his hands with a relaxed face, and saw the man who led the way, still standing at the door of the men's toilet waiting, with an expression of being ready to serve him to the end and send him back to the army.

Qin Xu smiled at him and asked, "Where is my boss, I have to hurry back to him, otherwise I will be criticized." ”

"Understood, come with me, they just went to the director's office together, just upstairs, I'll take you there. The man walked beside Qin Xu, looking enthusiastic, but in fact he was staring, although he was not sent to the office, he was also staring at him in the corridor.

Qin Xu didn't mind either.

Anyway, now that the location of the little black house has been determined, they can also start acting.

The wooden door of Director Liu Liwei's office was open, Huang Zhenghao and a few of them were talking happily with Liu Liwei, Qin Xu said to Huang Zhenghao a little anxiously: "Boss, there seems to be an urgent matter in the company, why can't you get through on your mobile phone?"

When Huang Zhenghao heard this, he said "sorry" to Liu Liwei and hurriedly picked up his mobile phone.

"Oops, I turned on mute, it's Xiao Li's phone. When Huang Zhenghao dialed his mobile phone, Zhao Chunjun pulled Liu Liwei to ask for details.

Probably because he felt that women were more careful and difficult, the director of the successful training school answered Zhao Chunjun's questions ruthlessly.

"Eldest sister, you think that our tuition fee of 30,000 yuan for two months is very expensive, but you look back and think about it, using 30,000 yuan to save the child's life, this is really very cheap......" Liu Liwei was like a river, not knowing that the security guard guarding the gate had been subdued by Xie Yibin and Chen Shujie, auxiliary police officers of the Changyang Branch, and was gagged and tied to a chair.

Since there are more than 100 students aged 10-18 in this training school, which has not yet found any licensing procedures, the police are very cautious in this operation, and they cannot be too careful.

Because the so-called instructors of the school were involved in violence and abuse of students, before the action, the superiors issued instructions to take the action policy of first controlling and then interrogating, and then conducting in-depth investigations under the condition of subduing and controlling the situation of all teaching staff in the school and ensuring the safety of the students.

Qin Xu saw Huang Zhenghao put down his mobile phone, so he turned around and left the office.

Qin Xu is the youngest in this group, Liu Liwei only regarded him as the follower of the big boss of the gold chain, raised his eyelids, and didn't care, just caring about Zhao Chunjun, who was a little difficult to deal with.

"The range you're talking about, part of it is covered under the classroom, and the likelihood of an exit here is very low. The toilets were also included and there was no sign of any entrance inside, so we went around to the back of the building to have a look. ”

Qin Xu muttered in his mouth, and then saw the brother who took him to the toilet, as if he had discovered something, and leaned on the window to look.

Qin Xu's long legs shortened the gap between the two of them in a few steps, his arm slammed his neck, and then he slammed this guy against the wall with inertia, cut his hands back, and handcuffed him.

At this time, this place, under the guise of a training school, controlled students through illegal and violent means to collect money, and only then did the muffled screams sound one after another.

In the director's office, looking at the parents who were smiling brighter and brighter, and when he felt very sure that these parents would leave their children behind, he was suddenly startled by some exclamations.

I saw that the wealthy businessman who was sitting on the sofa opposite with a big grin, with a nodly rich face, straightened his stomach slightly, stood up, took out a document from his pocket, and said in Mandarin with a slightly Chaohai accent: "Liu Liwei, according to the report of the masses, you are illegally running a school here and violently abusing minor students, please go to the police station to cooperate with the investigation." ”

Liu Liwei's face darkened.

But he didn't seem particularly flustered.

He sat down, leaning back in his chair, with his hands folded over his chest, glancing at the people present, and saying nothing.

"I'll go down with the others to help, Sister Zhao and Lao Yang, you control this person. Huang Zhenghao said directly.

What is the punishment of the law, they can't do anything.

But at this moment, as police officers, they can only do their best.

Qin Xu took the "instructor" who loved to send people to the toilet on the iron railing of the stairs to find the entrance to the small dark house underground.

As he ran, he saw that his colleagues had taken control of the classroom and the students who were training on the playground.

He was shocked that even though something suddenly happened, the classroom was silent, and more than half of the people, without even looking up, continued to write the rules of the training school on paper.

Only a few students secretly raised their heads, glanced at them, and quickly lowered them again.

The spirit that has been controlled by violence does not know when it will be liberated.

Qin Xu ran to the back of the building and soon found the farthest position, there was an iron door made of aluminum and silver.

On the iron gate, a large lock hangs.

Qin Xu had already made preparations, and took out a small transparent round box containing contact lenses from his trouser pocket.

On the small box, there were several small holes poked, and a little guy could be seen motionless inside.

Unscrewing the lid of the small round box, Qin Xu lured out the little black ants in the box.

This time, Master Qin didn't have any guidance, and the little black ant consciously got into the keyhole, and about five seconds later, the lock opened with a "click".

"Hehe, after you taught it last time, it seems to have slowly mastered the trick, I'm idle, throw it a few locks to play, and it can be opened!" Qin Xu said to Old Master Qin with a grin.

The iron door opened, and it was a very narrow small room, with a student desk, a stool, and most importantly, another door in this room.

A lock that is almost identical to the iron gate before it.

Qin Xu introduced the black ants that had crawled out of the keyhole into this lock.

This doorknob looks heavy, but it is indeed a piece of cake for black ants.

After Qin Xu opened this door, he saw stairs one step after another, extending to the ground.

The stairs were very narrow, and the dull air made Qin Xu feel particularly cramped when he walked in.

On the fifteenth floor of a staircase, Qin Xu walked three times, and then saw a particularly heavy anti-theft door.

With the all-round lock-picking black ant with amazing arm strength, it is difficult to stump Qin Xu with a door designed by basically ordinary mechanical principles.

The security door takes a little longer than a regular lock, about a minute, to be opened.

When the door opened, a terrified whimper came from inside the room.

From this point of view, the sound insulation of this security door is quite good.

Qin Xu pushed the door in.

He walked in so blatantly, it was Old Master Qin who determined that there was no one else in the underground area.

In the dark room, apart from crying, only the whirring sound of the exhaust fan sounded.

Turning on the flashlight, Qin Xu found the light switch.

The room was bright, and a boy of about sixteen or seventeen years old, shirtless and wearing a pair of trousers, was tied to a hospital bed, crying miserably.

When he saw Qin Xu in uniform, not only did he not have the joy of being saved, but his expression was distorted, and he screamed in pain: "Instructor, I won't! Please, let me go!"
