He replaced the fuse of the switch box, then turned on the independent computer in the workshop, started the three-dimensional picture, and pressed the sound wave detection.

"Dr. W special machine, enter the password." said the electronic female voice.

"Liu Yan." Liu Yan said: "Information password A, U..."

Electronic female voice: "Password is passed, please operate."

Liu Yan's breathing was finally exclaimed, and he breathed a sigh of relief and said with a smile: "Dr. Wei really understands."

"Your safety level is so high?" Xie Fenghua said.

Liu Yan said: "Before leaving, Dr. Wei asked me to be his assistant. Fortunately, the safety command was not cancelled. The overall picture of the United Front Work Department of Sound Wave Detection. The central workshop technicians' maintenance operations, first-level confirmation, and report the degree of damage."

Electronic Female Voice: "The seventh floor, the thirteenth floor, the fourteenth floor is damaged, the 440th atmospheric pressure strength, the danger level is ‘extremely high’, the sound wave penetrates and returns."

With a beep, the laser head emits rays, forming the entire sixth zone line diagram, from top to bottom, a total of nineteen layers, which is inverted at this moment.

The building line diagram is very complex, but fortunately it is three-dimensional, with many broken lines on each floor, symbolizing the damaged building.

Lai Jie murmured, "What are these?" He pointed to the circular tube-shaped moving objects on each floor. At a rough look, there were hundreds of them, slowly moving up from the gap in the building line diagram, gathering towards the eighteenth floor in all directions.

Meng Feng took a deep breath: "We are in trouble, why are we heading here?"

"It should be walking towards the nineteenth floor above our heads." Lai Jie said: "What is in the biochemical laboratory?"

"Stop worrying." Meng Feng said: "Come on and get out of here, hurry up!"

Liu Yan took out a thruster in the workshop and installed it for the deep-sea excavator. Taking this time, everyone held a brief meeting in the center of the workshop and formulated the route.

Lai Jie chose the farthest road and took a big circle, but the danger was the least. The eighteenth floor was very unsafe, so Zhang Min and Xie Fenghua had to follow him.

Lai Jie gave Xie Fenghua a pistol, and Li Yan said: "She can't walk anymore. Captain, am I responsible for carrying her?"

Liu Yan waved his hand and sat on the excavator. His robot arm clamped Feng Hua's slim waist. He stuffed her behind the excavator, touched her head, placed it, and began to walk around with a clang.

The xenon lamp has extremely strong penetration, and the entire corridor can be clearly visible after a illumination.

"Prepare--"

At the end of the deep tunnel, there were unrecognizable dangers in the darkness. Liu Yan took a deep breath, bowed the excavator, and the accelerator behind him rumbled, and black smoke was sprayed out.

"Run!" Liu Yan pushed the joystick, and the robot roared at the highest speed. Everyone followed behind him and began to run wildly, firing with machine guns on the side. I don't know how many obstacles were knocked away along the way. The robot rushed towards the partition at high speed, and the laser nozzle poked out. The partition exploded into pieces with a loud noise!

"Come on, keep up!" Lai Jie shouted.

Everyone followed the excavator robot to rush across the entire eighteenth floor. Liu Yan controlled the robot to punch the elevator door. Lai Jie shouted: "Jump up!"

Zhang Min, Meng Feng, Lai Jie, Wen Qige, Li Yan and the other five jumped up at the same time and slapped on the deep-sea operation machine. Liu Yan twisted the joystick and turned around happily. Propulsion smoke was sprayed out from behind the robot and slowly descended in the large armored elevator.

The energy grid continued to decrease, and Liu Yan was sweating all over his back, pushing the recoil joystick.

10%...9%...8%...thrust gradually weakens, and at the end of the elevator at the last 8%, it hits the ground with a bang.

The sole of the foot is a huge platform. After landing, the robot takes a step back. In front of it is an inverted elevator door, with fluorescent numbers displayed on it: 11.

There is no road below, the soles of the feet are inverted large elevator platform, and the sound wave scan shows that the bottom is full of sea water.

"We have to cross here and find the tenth floor on the way." Lai Jie said: "Is the energy enough to be blown up?"

Liu Yan replied: "It's not enough, just change the bomb."

Li Yan went to place the bomb. Three seconds later, several people quickly hid behind the excavator. Liu Yan pressed a button and the excavator pushed up the front shovel to block the blasting shock wave.

The door deformed violently, the robotic arm removed the steel door, and several people rushed into the eleventh floor.

"Safe for the time being." Lai Jie glanced at the map on the wall: "Everyone separates and go to find the passage that has not yet entered the water. Liu Yan, you can stay here to be responsible for the dispatch, can you?"

Liu Yan glanced at the open elevator door behind him and replied: "It should...no problem."

Meng Feng was still not relieved, so he glanced around and said, "Come here."

Zhang Min said: "Give me a communicator and I can help you too."

Liu Yan threw out a badge, Zhang Min raised his hand and grabbed the collar, took the AK and prepared to join the battle.

The eleventh floor is the Air Force floor, and there are many inverted bunkers in the side training ground. Meng Feng chose the safest place and said, "You guys hide here."

Lai Jie said: "There is no time left, so let's go and find the path. Liu Yan is in the middle to support him. It will be safer to find the path as soon as possible."

The eleventh floor is very large and is the most spacious office area in the entire sixth district. The five people each chose one direction to spread. Liu Yan took out Xie Fenghua from the excavation bucket, opened the hood of the deep-sea operation engine room, stuffed her in, and opened the communication box in the narrow space in the cabin.

The light spots on the screen move in five different directions, close to the immersed floor, most of the passages are flooded by sea water. They want to find a passage without water and then retreat in a concentrated manner.

According to this search time, it will take at least half an hour.

"Philosopher, how did you know Li Yan? What do you think of Wendi?" Liu Yan pondered for a moment, turned off the other four communicators, leaving behind a one-way communication with Wen Qige and Meng Feng.

Xie Fenghua: "..."

Meng Feng: "If you dismantle an official partner, you will be struck by lightning. Please be careful that the philosopher will give you a shot in the back of your head."

Liu Yan said casually: "Go to the gossip, why are you doing so serious?"

Xie Fenghua didn't have time to say a few words to Liu Yan until then, and said with a smile: "Brother Wen is a handsome guy, a good man, um... a very gentle and gentleman, a perfect person, and can do magic, there is nothing to say. I'm more curious about you, Doraemon. I heard that you had a big fight with General Meng? Did you win in the end?"

Liu Yan turned his head and saw Xie Fenghua holding a recorder in his hand.

"Oh, this kind of professional habit is obviously very bad, philosopher." Liu Yan said: "I heard that you said a lot of bad things about General Meng in the communication publication. He must regret letting you enter the propaganda department of the United Front Department."

Xie Fenghua said: "People always need to listen to different voices. Uh... Actually, General Meng is a very interesting person, but his position is not very consistent with us."

Liu Yan's eyebrows moved: "What position? What position do you represent? District 7?"

Meng Feng said: "Liu Yan, you are obviously no match for others. You were led away after just a few words."

Liu Yan: "No, I want to gossip and point something else now. Feng Hua, what do you know about the inside story?"

Xie Fenghua whispered: "Of course not, what position can I stand for? But now everyone is looking for the truth... do you know? They found an Oaks complex in the deep sea, and successfully dismantled it with our current excavator... and got something."

Liu Yan: "What's it?"

Xie Fenghua shook his head, held his chin with one hand, and his beautiful eyebrows bent.

"They said that it was the 'nucle' of the Oaks complex." Xie Fenghua said: "It's something called a string. If it is detailed, we won't know. It is said that the 19th floor biochemical laboratory is already studying the truth about this virus wave, but the entire Seventh District was angered by General Meng's long night plan and was unwilling to share information again..."

Liu Yan immediately took out a piece of paper and said, "Look at this, Fenghua, what do you think it looks like?"

"I think I saw that thing." Liu Yan said: "It's a ball of blue light. Look, the analysis report of Dawn 5000A records these on paper..."

Xie Fenghua looked at the paper at the cabin ceiling light.

Meng Feng said: "Liu Yan, turn on all communicators."

Liu Yan turned on the communicator.

"Like the fluctuation research in earthquake zones." Xie Fenghua said: "It's not very regular... is it an electrocardiogram?"

Liu Yan said: "No, it's not an electrocardiogram. The electrocardiogram is regular. This should be a kind of wave, but I don't know much about the actual content..."

Lai Jie asked: "What are you talking about?"

Neither Liu Yan nor Xie Fenghua answered, and Xie Fenghua finally said: "Like a brain wave frequency drawing."

Liu Yan: "..."

"So what?" Liu Yan said in a deep voice.

Xie Fenghua said: "The blue light you see must be the sampling obtained by the Biochemical Laboratory of the United Front Work Department in the deep sea. The sampling report shows that the blue light may have ideas, it is something called 'string'."

Liu Yan: "Lai Jie, I remember you mentioned this too..."

Lai Jie said: "I don't know. I heard Wu Shuangshuang say that. The seventh district only talks about this noun and does not explain it in depth."

Liu Yan: "What happens if you see it?"

Lai Jie: "Who knows, some people say they will die if they see it..."

"This is bullshit, it's obvious that I'm fine." Liu Yan finished speaking.

A loud bang came from the communicator!

"Liu Yan!" Meng Feng roared.

"Maple Birch!" Li Yan's hands and feet were cold in an instant.

Liu Yan shouted: "Fenghua! Hold on to it!"

The entire excavator was turned over, and a huge octopus sneaked into the training ground silently at some point.

It was the complete body of a zombie octopus, seventy or eighty meters long, with a huge gray head bubble almost transparent, eight tentacles moved flexibly, grabbed the robot's robot's robotic arm and threw it to the ground.

When all the octopus tentacles are kept intact and grown on an octopus' head, this deep-sea monster is by no means comparable to the power of a few broken tentacles. Before Liu Yan could even start a war, his two robotic arms were torn apart by huge force.

Everyone turned around at the same time and rushed towards the location where Liu Yan and Xie Fenghua were.

Liu Yan finally touched the laser emission button and pressed it. The laser gathered energy. With a buzzing sound, it consumed the last five-unit energy. A hot laser shot at the head of the octopus, and a bang exploded the brain fluid flying all over the sky, turning into a limp ball, and tentacles couldn't help but twitch and spasm.

Liu Yan gasped and said, "Hey, where did this guy get out of..."

As soon as the words were finished, eight tentacles connected to the blown-up octopus' head moved again.

It's over. Liu Yan thought to himself.

At that moment, Meng Feng yelled in despair, the hatch was lifted open, the excavator hit the wall, completely crashing through the inner wall of the entire training ground!
