Chapter 200 Defense Line

The lights in the main control room were dimmed to gray, and Su Wanqing stared at the changing numbers on the wall.

Lu Zhao sat beside her, and the two checked their watches for the last time. Xiao Ran sat at the far end, his face close to the communication headset, and adjusted the backup power switch to maximum power.

At 2:50 in the morning, the notebook in Lu Zhao's hand lit up with a blue code stream.

His fingers typed quickly, and the indicator lights of the power distribution system in Area B went out one after another.

The outline of the monitoring screen showed an "abnormal" prompt. ——Opportunity, there will only be this moment.

Su Wanqing put on gloves and checked the connection point between the jade bracelet and the first energy core to make sure it was consistent with previous preparations.

Lu Zhao interrupted the silence with the briefest words: "The power distribution cascade system will collapse in five seconds, hold on tight."

The technician behind them, named Song You, is one of the rare silent veteran electricians in the base.

He nodded, pulled out a few old cables from the toolbox, and was the first to go into the abandoned maintenance passage.

Su Wanqing and Lu Zhao followed closely behind. There was no light in the entire corridor, only the sound of one's own breathing in one's ears.

The walls of the pipe were seeping with cold air, and the three men climbed more than ten meters in silence.

Lu Zhao took out a wireless signal detector from his backpack, and the screen was silent.

He whispered, "Monitoring blind spot, reading normal. Fifteen-second window."

Su Wanqing aimed the jade bracelet at the side wall of the pipe and activated the interference function.

As the pointer slid, she keenly discovered that the electronic isolation zone, which was supposed to be one and a half meters wide, was only disturbed by less than half a meter.

She pursed her lips and signaled Lu Zhao to stop: "The range has shrunk too much. We can only change the route with Song You."

Song You put his hand on the pipe mouth, took a breath, and frowned: "Take the southern branch instead of the main pipe?"

Su Wanqing ordered the noodles and without saying a word, she scratched the original route to the bottom of the waste compartment.

She wondered why the interference effect of the jade bracelet was much weaker than in the low-temperature experiment.

Lu Zhao followed up and pressed the microphone: "The original route of B1 and C2 points has been abandoned. We will go to the unit from the lower level of the gate valve control room."

Xiao Ran's short reply came from the communication: "Got it, hurry up, a shift in the west district is moving to the main road."

The three of them walked on the iron plate, passed a fence that was rusted by water vapor and went underground.

On the way, two patrol sentries crossed the main road. Song You was still crouching, and the wrench on his waist touched the pipe wall, making a crisp sound.

Su Wanqing switched the power of the jade bracelet with her backhand, and the electrical interference instantly covered up the sound of footsteps.

The three of them paused for a moment, until the noise of the walkie-talkie in the distance became blurred, and then they slowly walked through the narrow passage.

When entering the waste bay, Lu Zhao pulled up his sleeves and said, "The patrol table on the right is being adjusted. The next shift will be in two minutes."

Song You gritted his teeth and tightened a bolt: "There is a secondary line of defense in the gate valve control area, speed up."

The few of them did not delay any longer. Su Wanqing observed the slight heat transmitted by the first core in the jade bracelet, and felt that the restricted energy was released with all her strength.

They had to abandon the original "main control loop cut-off plan" and approach the target area via a more risky reverse small pipeline.

After passing through the spare machinery room, the third patrol's footsteps were heard from the metal plate above their heads.

Lu Zhao held his breath and turned off the instrument. Song You tucked the tools under his armpits and hung them behind the fire door.

The sentry walked very slowly, and the shadow of his light was cast on the crack of the door from time to time.

The three of them tried their best to hide their bodies, and only dared to hold each other's arms. After making sure that the light was far away, they lowered their heads and walked slowly forward.

When she was fifty meters away from the core of the generator set, Su Wanqing saw a newly installed access control system in front of her, with an infrared scanner and text prompts embedded on the top: biometric verification, pressure plate sensing floor.

Lu Zhao judged that the situation had changed, and immediately moved closer to the door control panel, pulled out a palm-sized tablet, and powered it with a backup battery.

There was a slight sound of electricity coming from the side panel of the access control. Lu Zhao knocked on the port and whispered, "It will only take a few seconds to reconstruct the system, but there will be residual data. The shielding will only last for two minutes."

Song You was waiting on the side with his tools in hand. Before entering the door, he said, "Be quick. Someone will be watching if there are traces left during the inspection."

Su Wanqing looked around, put one hand on the jade bracelet, and moved the other hand along the niche, trying to get her body as close to the corner as possible.

Twenty seconds later, the access control system unlocked with a "ding ding" sound, and a small opening appeared in the electromagnetic door panel.

The three of them crouched sideways and slid in. Just as they stood firm, the lock cylinder outside the door reset, and the indicator light on the circuit board switched back to red, indicating that the system had taken over control again.

The interior space is cramped, with heavy metal pipes and low railings everywhere.

The temperature suddenly rose. There was a special isolation wall in the core area ahead. As Su Wanqing approached, the temperature on the surface of the jade bracelet rose to a new height, and she immediately noticed the reaction of the second energy core.

Under the light source at the end of the quarantine area, four military soldiers stood in separate positions, guarding with guns.

In the middle is a thick special alloy container with a signal shield on the top and two independent electromagnetic locks on the outside. The container is under the protection of this group of soldiers.

The soldiers' alert status was extremely standard, without any slackness at all.

Lu Zhao took a peek from the inside and muttered, "The military themselves have also realized that this thing is unusual."

Song You couldn't stop shaking, and urged in a low voice: "How should we take it? This is so complicated..."

The latest novel is published first on Liu9shuba!

Su Wanqing put the jade bracelet on her sleeve and closed her eyes. She felt a slight pulling sensation in the bracelet, and she felt that the core was just a few meters away from her, but she couldn't get close to it for the time being.

At the same time, in the main control room of the fortress, Xiao Ran supported his chin and stared at the monitoring screen.

The screen in the back row suddenly flickered. He zoomed in on the surveillance screen and found a figure swaying near the main duct of the west area ventilation system.

He didn't have much time to think, and immediately switched to the security intranet and called two trusted personnel from the technical department: "Go to the west ventilation main duct immediately and pay attention to whether there is any device."

Ten minutes later, the report came in. Two officers carried three small devices.

Xiao Ran picked up one of them and looked at it again and again. Each device shell glowed with cold metal, and underneath the shell was a fine antenna and an adaptive power port.

He used a meter to measure the band. The frequency was different from the main frequency used by the fortress, but it continuously emitted an extremely low frequency signal.

Xiao Ran handed the device to the network specialist and said, "Trace where the signal comes from and who has the authority to be in this area recently?"

The specialist stared at the instrument, frowning, “The type of device is similar to the signal relay commonly used by the military, and it also has the potential for interference and positioning.

The source is too hidden, and the background data cannot be found. It may be controlled by an external remote control, or it may be a mole inside the fortress. "

Xiao Ran took a breath and quickly wrote down the number. He stared at the screen and kept switching surveillance, trying to find more abnormal points.

All the scenes are silent and the atmosphere is tense.

In the core area of ​​the generator set, Su Wanqing was lowering her movements and scanning the corner of the wall.

Four military soldiers leaned on both sides of the alloy container, fully armed and expressionless.

Lu Zhao took a half step back and whispered in the communication: "Xiao Ran, the four people outside are fully armed. The alloy container has a special lock control. It will probably take sudden action to get the core."

Xiao Ran replied: "Observe first. Someone has been found tampering with the main ventilation duct at the base. We have confirmed that there is a mole. You must be more vigilant. If the plan changes, please contact us temporarily."

Lu Zhao turned down the volume of the communication to the lowest, turned around and said to Su Wanqing and Song You simply: "We can only get close to them with the jade bracelet for the remaining few meters. We have to make preparations and disperse in case we are exposed."

Song You nodded repeatedly, holding the tool tightly in his left hand. Su Wanqing approached the corner, the temperature of the jade bracelet continued to rise, and the core was behind the isolation wall.

But the signal isolation effect of the special container made her feel difficult to approach.

After a moment, one of the soldiers on duty turned his head and looked in the direction of the three people. Lu Zhao pressed the button on his cuff, indicating that he was ready to retreat.

Just as the three were concentrating on thinking of countermeasures, the LED indicator light on the far wall began to flash slightly, and the sound of water could be heard in the internal pipes.

The four soldiers did not relax their vigilance and continued to patrol in turns according to the squad formation.

Su Wanqing held her breath and studied every tiny path that might approach.

The jade bracelet felt hot in her palm from time to time, and she subconsciously knew that not a single opportunity could be wasted.
