When we returned to the bureau after dinner, Shen Yu and I went to the comprehensive office and got a special access card for visiting Gu Baotian's secret base. I heard the eldest sister in the department say that there are only five people in the entire bureau who have this kind of card.

"I didn't even do it to the director." The eldest sister emphasized repeatedly.

Armed with access cards, we drove straight to the secret base.

Unlike the original, Gu Baotian's ward was on the fifth floor of the basement. He was guarded on a floor without windows, and had to go in and out only by an elevator that had to go up from the first floor to the twelfth floor, and then transfer to another elevator from the twelfth floor to get down. Of course, all elevators require a credit card.

"Isn't there a fire escape?" I asked the accompanying security officer.

"Of course there is, but every floor, every door is locked, if there is really danger, then the central control room will be unlocked, otherwise no one can get out, no one can get in - to put it bluntly, the entire floor is closed, all maintained by a ventilation system, you can think of it as a gravity capsule."

"Understood." Shen Yu said, "This is also the highest level of security that can be designed, right?" ”

"You haven't seen anything more exaggerated." He dropped us off the elevator, stopped and said, "I don't have access anymore, I wish you both the best." ”

We took the elevator from the twelfth floor down to the negative fifth floor, opened the elevator, and in front of us was a gray-white cement wall.

"What's going on? Got off the wrong elevator? "I was hesitating to go back, but the wall slowly opened a square hole the size of a man's face, and there was still a green glow inside.

"Please swipe your card." The square hole said.

We put the card into the square hole, and the square hole played happy music for two seconds.

"Please brush your face." Fang Kong continued.

"Yes." I had to rest my chin under the square hole, and a second later, it was the same pleasant music again.

"Please don't leave, Irisa scan is going on right now." Square hole reminded.

The pleasant sound of music sounded again, and I felt that this time I must have passed the test, and who knew that Fang Kong would speak again.

"Please say a sentence of no less than ten words for voiceprint verification."

"I'm your uncle, I'm your uncle."

"Thank you! Your identity has been confirmed, please wait. ”

The tight concrete wall suddenly rumbled, and a door appeared from the wall as if it had surfaced.

"Magical." I walked in admiration, and Shen Yu wanted to add a stopper, but was almost juicy by the cement wall that was then closed.

"Sorry, please return the intruder for verification."

There was a glass door inside the cement wall, and two chairs were placed in front of the glass door, which must have been for the first to come.

It seems that the designer is still relatively human, knowing that it is quite troublesome to verify one by one, and it takes a long time for the first to wait for his companions.

After a long time, Shen Yu came out of the door.

"His uncle, he said that my voice didn't pass, and scolded it for three minutes!"

I laughed out loud: "Was it entered according to Hua Hu's voiceprint at that time?" ”

"How do I know?! I didn't collect this information when I applied for the card! I don't even know when they collected it! ”

"In modern society, where is the privacy of individuals?" I comforted her.

The two of us passed two more certifications, and then we walked into a corridor that was as bright as day. The white light in the corridor was dazzling, and I couldn't understand why they had to make it so bright.

It was Shi Chong who came out to greet us.

"Two teachers, how's it going? Is this place where flies can't even fly? ”

"Yes, flies have to be annoyed by the identity verification of one pass." Shen Yu said.

"Hahaha, we plan to use this as the general command base of the special group in the future." Shi Chong said proudly, "Now Gu Baotian and the student who assassinated him are here. Oh, by the way, the student's motive for killing has been ascertained, is Mr. Shen interested in hearing about it? ”

"Say it, and ask for Mao's opinion." Shen Yu scolded him.

"This person's name is Zhang Yunqiang, and he was Gu Baotian's student back then. At that time, he didn't study well, and his temper was even worse, he often quarreled with teachers and classmates, and smashed tables, chairs, benches and other things when he made a lot of trouble, he was just a grumpy old brother.

"The middle school where Gu Baotian taught in his early years was on Jiangxin Island. There are only two facilities on the island, one is a school and the other is a park. The park is open, and people around are walking around the park via a bridge.

"Because Jiangxin Island was protected for a long time, there are many trees and birds in the park. On the day of the incident, Zhang Yunqiang was in class on the third floor, and when he went out between classes, he happened to collide head-on with a classmate.

"How short-tempered he is, he grabbed that classmate by the collar and grabbed it, that buddy is not good at stubble, the two of you quarreled with me.

Seeing that the situation was escalating more and more, and the two of them were about to make a move, Zhang Yunqiang's arms were raised. At this time, I only heard a "pop", and the window glass next to them suddenly burst and fell down with a bang.

Gu Baotian was the head teacher of this class, he happened to walk up to him, and saw Zhang Yunqiang swing his fist, and then the window glass shattered. He subconsciously thought that Zhang Yunqiang was burning and destroying public property.

"Of course this kind of thing has to be dealt with. Zhang Yunqiang and the classmate were called to the office by Gu Baotian, Gu Baotian first criticized the two of them, and then asked them to make half of each of them compensate for the glass money. ”

"So, Zhang Yunqiang is in a hurry?" I asked.

That's right, Zhang Yunqiang thinks he has been wronged. He insisted on not admitting his mistakes, not compensating, and competing with Gu Baotian.

Originally, if he insisted on it all the time, Gu Baotian might re-check the matter, but at this time, another classmate wanted to calm things down and didn't want to be entangled like this, after all, a piece of glass didn't cost much.

So he took the initiative to admit his mistake to the teacher, admitting that the glass was broken by the two of them in a fight, and also agreed to the teacher's punishment and was willing to lose money.

This completely put Zhang Yunqiang on top. He was still trying to plead, but the prisoner was playing and the other person had already pleaded guilty, and his non-confession became a sign of misdemeanor. ”

Gu Baotian was also angry, he told Zhang Yunqiang to call his parents in the afternoon. In the afternoon, the whole thing went completely out of control.

"The first session in the afternoon is Chinese, and it is also Gu Baotian's class. When he entered the door, he found that Zhang Yunqiang's seat was empty, and asked the classmates next to him, but they didn't know where this guy went. Gu Baotian thought that he was going home to find his parents, so he didn't ask in detail.

He then began to lecture, and in the afternoon the sun was warm, Gu Baotian yawned as he spoke, and the students were also drowsy. Just when everyone was listless, they heard a loud bang, and the back door of the classroom flew in! ”
