Lingling immediately called up the real-time picture, there were only employees in and out of the corridor, but after searching the entire building, there was no trace of the water delivery worker. Lingling's face was sweating, adjusting the surveillance screen back and forth.

Li Dongsheng thought calmly for a while: "Wan Lin, the other party is missing in the emergency corridor on the second floor, search from the corridor, pay attention to safety!" ”

Wan Lin heard the reply, ran to the corridor with Xiaohua, went up to the stairwell on the second floor, only to see a bucket of mineral water standing alone in the corridor, Xiaohua ran straight to the corridor door, Wan Lin quickly opened the corridor door, and reached out with his right hand, and there were three more steel needles in his hand.

Xiaohua ran directly to the bathroom door along the corridor, turned her head and glanced at Wan Lin, Wan Lin stood sideways to the bathroom door, listened to the movement inside, slowly squatted down, pushed the door open, rolled forward and rushed in, Xiaohua slipped by the door and got into it at the same time.

The bathroom was quiet, Wan Lin squatted on the ground, and the steel needle in his right hand was tightly attached to his side, ready to be thrown out at any time. Xiaohua's eyes lit up and jumped on the bathroom partition, searched back and forth, and then jumped to an isolation door and squatted, wagging her tail at Wanlin.

Wan Lin got up and put away the steel needle with a shake of his hand, walked quickly to the isolation door and pushed the door open, and saw a clerk inside with his head drooping on his chest, wearing only a pair of underwear and sitting on the toilet. There were piles of water delivery workers' clothes and pants next to him, and Wan Lin reached out and touched the carotid artery of the employee, only to find that he was only knocked unconscious.

Wan Lin picked up the intercom: "An employee was knocked unconscious, and the other party went out of the bathroom on the second floor wearing a company staff costume."

When Lingling heard the words, she hurriedly played back the surveillance of the corridor on the second floor, and sure enough, she found that a thin company employee walked out of the bathroom with his head down, his hand covering his cheeks, and quickly went down from the stairwell to the underground parking garage.

At this time, Xiao Ya had already taken Xiao Bai into the laser room of the research institute on the third floor. Cheng Ru stood behind the glass screen outside Liu Hongxin's office with his hands on his waist, and looked at the ...... corridor through the gap in the screen, and all the commandos entered a state of readiness at their respective posts

Lingling and Li Dongsheng stared closely at the camera in the underground garage, and after the people with their hands and cheeks entered the garage, their bodies quickly shook between the parked vehicles, and disappeared behind a car in a blink of an eye.

Wan Lin chased him to the underground garage, suddenly jumped up, pulled out his pistol and moved quickly between the parked vehicles with Xiaohua.

Moving quickly around the spacious depot will help you avoid being targeted by your opponent and make it easier to quickly search for enemies.

Wan Lin and Xiaohua moved quickly for a while, and Xiaohua stopped next to a van. Wan Lin followed and looked down, only to see a sewer grate next to the van. Xiaohua stretched out his claws and was about to shoot the iron grate, Wan Lin raised his hand to stop it, looked around, took out the walkie-talkie and said: "The other party has escaped from the sewer, please indicate the next move."

Li Dongsheng breathed a sigh of relief, hesitated, and said into the microphone: "Withdraw." It was too dangerous to pursue the enemy in such a narrow space as the sewers, and he couldn't let Wan Lin and Xiaohua take the risk.

Lingling wiped the sweat from her face. The situation just now made her nervous face covered with sweat, and she muttered: "Watching Wanlin's movements here, I am more nervous than I am at the scene."

Li Dongsheng smiled, took out the phone and reported the situation to the National Security Bureau, asked them to send someone to check the surrounding sewer exits, and sent an ambulance to take the injured employee to the hospital for treatment.

His mood just now was as nervous as Lingling, and it was really unbearable for them, the commandos who were good at charging into battle, seeing their comrades walking through the danger.

A few hours later, Qian Bin of the State Security Bureau called and said: "We searched the surrounding drainage outlets and found that at the time of the incident, a truck was parked 3 kilometers away from the development zone, and under the truck was an iron grate of a sewer. Upon inspection, the grate showed fresh signs of being moved. It was obviously a premeditated action by the other party. The truck was found in a remote suburb 60 kilometres from the city, and the occupants of the truck were nowhere to be found. Team Lai, the other party launched an operation in broad daylight, what do you estimate the purpose of the other party's operation? ”

"It's hard to judge the specific purpose, I'll take a look at the monitoring again, and I'll communicate with you if there's any situation" Li Dongsheng pondered and hung up the phone.

At this time, Wan Lin walked in with Xiaohua, and Li Dongsheng asked, "How do you feel about the people who came?" Wan Lin shook his head and said, "I didn't see my face at all." However, this person should be the person who invaded Mr. Yu's study last time, otherwise Xiaohua would not be familiar with his taste."

"Come and see, this man's movements are really sensitive," Lingling shouted from within. Li Dongsheng and Wan Lin walked into the room and saw Lingling looking back at the surveillance video.

Wan Lin stared at the screen for a while, and said: "This person's light and soft skills are excellent, you see that he walks so quickly on the ground with a 25-kilogram bucket on his shoulder, and turns around so lightly, this person has a certain foundation of internal strength." It must have been someone who invaded Mr. Yu's study."

Li Dongsheng looked at it for a while and said, "Although this person deliberately blocked his face, he still showed part of his skin. This person is about 1.7 meters tall, with a thin body and very white skin, and should be male judging by his movements. The details are up to the NSA experts to analyze. Lingling, you pass on the information with the image of this person."

Li Dongsheng turned around and asked Wan Lin: "What do you think is the purpose of the other party's invasion this time?" Wan Lin shook his head and said, "It's hard to guess, it's unlikely that the purpose of the daytime invasion was to steal information. Hey, no, how did he know we found him? ”

"Play the video of the other party disappearing on the second floor again," Li Dongsheng quickly turned to the screen. In the picture, a dignitary carrying mineral water on his shoulder to deliver water to the office suddenly paused, then reached out and touched his ear and turned around and walked into the stairwell.

"Stop" Li Dongsheng shouted: "The other party found the exposure here, you look at the time, it is 15:40 at this time." Then adjust to the time when Xiaohua found the tracking".

Lingling hurriedly switched to the camera of Xiaohua bowing her head vigilantly in the group's courtyard, and the two pictures were displayed on the screen at the same time, and the time was 15:40. Wan Lin was holding up the walkie-talkie and saying something.

"The other party monitored our walkie-talkie frequency! You see that the other party's reaction is synchronized with Wan Lin holding the walkie-talkie and speaking," Lingling suddenly called.

Li Dongsheng smiled: "I said how they reacted so quickly, we just found him, and he knew." Hehe, I have to find the National Security Bureau to change equipment."

"Yes, raise your hands in favor, our walkie-talkie is a civilian product distributed by the group, and the confidentiality is too poor, or Wan Lin will catch this water delivery worker. It's really a failure, ruined in the performance of the product, and it must be replaced," Lingling said excitedly on the side.
