Lin Guoguo then pulled up the phone again, and after the phone was connected, Lin Guoguo said anxiously: "Ruyi, are you off work?" ”

Lin Ruyi heard his father's hurried voice and said with a smile: "I'm about to get off work, is my father going to check my post to see if I'm at the end?" ”

"It's not to check your post, it's good that you didn't leave, you quickly connected the command system to the city's monitoring, your Uncle Ou was arrested just now."

"Ah, what's going on?" Lin Ruyi exclaimed.

"I'll talk to you again when I go back, and I'll go back to the command center right away." After Lin Guoguo finished speaking, he hurriedly walked towards the outside of the school.

Outside the campus, Xiaohu and Juanjuan had already taken the bus and left first, leaving Nuan Nuan alone waiting for her grandfather.

Nuan Nuan saw her grandfather hurriedly walking out, so she opened her mouth to remind: "Grandpa, be careful not to fall." Why are you in such a hurry? Are you afraid that I will be in a hurry? ”

"No, let's get in the car." Lin Guoguo took out the keys from his body and trotted to his car.

He was concerned about Dr. Ou's safety, and he had to hurry back to the command center to take command.

Nuan Nuan was very depressed, what made grandpa so anxious?

It seems that her pit grandfather has always been very calm, and his face will not change when the sky falls, did he take the wrong medicine today?

With questions, she sat in the passenger seat.

The car started, Lin Guoguo stepped on the accelerator violently, and the car drove off like a fly.

Nuan Nuan's head was knocked on the chair, and she said dissatisfiedly: "Grandpa, can you slow down, why are you doing so fast?" ”

"Nuan Nuan, no, Dr. Ou was captured by an evil spirit in front of me just now." Lin Guoguo drove the car and said hurriedly.

After hearing this, Nuan Nuan exclaimed, "What? Teacher Ou was arrested? ”

It was okay just now, but how it was captured by the evil spirit in a blink of an eye, it's unbelievable.

"Yes, I witnessed it with my own eyes, I have just informed Marshal Runde, I hope everything is still in time." Lin Guoguo was very worried, and his hands were not good, and the car was driven by him staggeringly.

Nuan Nuan saw that her grandfather was not in a good state, and she was worried about a car accident, so she persuaded her: "Okay, grandpa, don't talk, drive seriously." ”

Lin Guoguo was reminded by Nuan Nuan, and he quickly regained his mind and concentrated on driving the car.

His heart gradually calmed down, and he also knew that it was useless to be anxious. He drove smoothly all the way back to the command center.

The people in the command center have already gotten off work, only Lin Ruyi is still sticking to her post, when she was about to get off work just now, she received a call from her father, saying that Dr. Ou was arrested, so she stayed, and at the moment she was busy, using the command system to connect the monitoring of the whole city.

On the screen, the real scene of each street and alley is displayed.

Lin Ruyi's eyes were staring at the screen, and he didn't dare to relax for a moment, looking for the arrested Dr. Ou.

At this time, it is the peak time to get off work, and it is really difficult to find the figure of evil spirits from the crowd.

Lin Guoli came in with Nuan Nuan, Lin Ruyi didn't notice, Lin Guoli saw his daughter looking at the monitoring seriously, he hurriedly walked over and said, "Ruyi, did you find anything?" ”

Lin Guoguo's voice frightened Lin Ruyi, she looked back and found that it was her father and Nuan Nuan who came in.

Lin Ruyi shook his head with a wry smile and said, "After I received your call, I used the command system to connect to the monitoring of each street, focusing on the streets near the Science and Technology Primary School, and I didn't find anything unusual. ”

Lin Guoguo and Nuan Nuan sat down and stared at the screen.

At this time, Lin Guoguo's mobile phone rang, it was Runde calling, and he reported the situation to Lin Guoguo.

Now the road into the city is blocked, and the sky outside the city is also being monitored, and if there is something unusual in the air, the defense system of Technopolis will attack on its own.

Lin Guoguo asked him to send someone to the scientific research center to collect the evil spirit detector, and asked the soldiers to search with the detector.

The Evil Spirit Detector was developed a month ago in order to prevent evil spirits from infiltrating important places, and once they find suspicious people, they use this detector to scan them.

This kind of detector has not been mass-produced, but it has been installed in an important place in the Science and Technology City, and it has not been installed at the gate of the city, so let the magic flow bring people in and arrest Dr. Ou.

After Lin Guoli finished explaining on the phone, he continued to stare at the screen.

As the minutes passed, it seemed that it was getting dark, and no suspicious characters were found in the surveillance.

At this time, Nuan Nuan said softly: "Grandpa, if we call back the surveillance near the school, maybe we can find their traces." ”

"Nuan Nuan is so smart, grandpa is really confused, and forgot to call the monitoring back to see." Lin Guoli gave Nuan Nuan a thumbs up.

Then Lin Guoguo tapped the keyboard in his hand, adjusted several surveillance cameras near the school back to the time point of the incident, and then played back the monitoring.

Finally found the clue, a black fog floated out of the sky above the school, this black fog did not drift far, it fell on a remote street near the school, the black fog dissipated to reveal two people in black and the unconscious Dr. Ou, one of the men in black opened a manhole cover on the street, and then they took Dr. Ou into the sewer.

Lin Guoguo was dumbfounded, the clue was interrupted here, how can this be checked?

"How can I find this!" Lin Guoguo sighed softly.

Nuan Nuan's eyes rolled and he said: "Grandpa, don't worry, as long as they are still in the city, there is a way to find them, this science and technology city was designed by you, you know best which exits are from this sewer, and then send troops to search near the exit of this sewer." ”

"It seems that this is the only way to go." Lin Guoguo sighed.

Then, Lin Guoguo reported several place names and asked Lin Ruyi to switch the monitoring to these places.

Then he called Runde, reported several key locations, and asked Runde to send people to focus on searching these places.

Runde told Lin Guoguo that the soldiers had only retrieved three evil spirit detectors, and he was afraid that he would not be able to search for evil spirits in the first place.

Lin Guoguo told him not to worry, search one place after another, anyway, in the city, there will always be a time when he will be caught.

After Lin Guoguo hung up the phone, Nuan Nuan asked, "Grandpa, is the evil spirit detector really so powerful?" Can you show me a little bit of it? ”

"Of course, we have installed this kind of detector in our command center." Lin Guoguo stood up and pointed in the direction of the gate.

Then he took Nuan Nuan to the door, there was a slender lamp on the door frame, Nuan Nuan looked at the lamp with curiosity.

Looking at Nuan Nuan's curious appearance, Lin Guoguo said with a smile: "If there is a suspicious character coming in, we only need to press this small button lightly, and the light tube on it will emit infrared rays." ”
