Chapter 158 Cracking Attempt
Xiao Ran raised his head, holding the handle of his helmet. When he entered the room, he didn't say a word, quickly put down his weapon, and wiped his sweat with a piece of cloth.
"The ones outside the main gate had a device I had never seen before. It was the size of a box, with a silver-gray shell and three folding antennas plugged into the side. Someone was calibrating it with red and blue lights in the back."
Su Wanqing stared at the screen without looking up, and turned to the latest page of the current homework record.
"Does it match the data of the microwave signal source we just picked up?"
"It's about the same. Every time they move, the data will shake. The formation advances in a fan-shaped formation, and the leader's hands are all filled with boxes. I guess they are using them to find the pendant signal."
Xiao Ran patted the cloth bag and whispered, "It can also be linked wirelessly. Just now, the team's light flickered and the main channel signal became even more chaotic."
Lu Zhao looked up from the other end of the passage and handed the terminal to Su Wanqing.
"The signal vector drifts significantly, and there are directional peaks every once in a while, which is basically consistent with the main frequency of the pendant. This tracking device is probably set according to the data stream of the pendant."
Su Wanqing nodded, stared at the string of jumping data and asked Lu Zhao to stop.
"Are you sure you can locate the pendant?"
Lu Zhao pointed at the algorithm model at the top of the screen, his tone expressionless.
"The matching rate is over 95%. The only difference between the protocol and the pendant we have is the check bit. The embedded module should also be able to change the tone in real time." He paused and amplified a recorded interference signal. "The initial frequency hopping value of the tracking device coincides with the base bandwidth of the pendant."
While Lin Che was adjusting the various small modules in his backpack, he asked him, "Do you have any ideas?"
"Yes, we have to switch the pendant's signal band to a non-standard area. Since the rebels' equipment is synchronized with the pendant, once the frequency changes, they have to spend time slowly re-locking."
Lu Zhao did not hesitate, and took out the debugging interface cable of the pendant and removed a section of the old motherboard microchip. "The simulation environment is ready. I will first sample the signals they often use and make a corresponding obfuscation group."
Xiao Ran looked at the light outside the gate, and his voice became lower than before.
"The noise over there is getting louder and louder, hurry up."
Lin Che installed the water energy storage battery into the auxiliary unit, and then bit the corner of his mouth while operating it, "I can use my supernatural power to send a false feedback to the main signal. Once the interference wave group comes online, they should think that the target has moved."
Su Wanqing was worried, so she pushed the device closer and inserted a backup key. "Lin Che, keep all the data flow logs here to ensure that the logic is not lost."
Lu Zhao noticed it, retracted his right hand and said, "Okay, I have recorded the analog tracking signal on the left side of the pendant's main interface, and will import it in batches in real time."
The surface of the pendant was slightly warm, and the data cursor was jumping on the device.
Lu Zhao disassembled the box while transferring the data, and connected the original fitting signal module and the newly inserted interference chip together.
Lin Che had already started activating the auxiliary resonance device on the other side. "Switch the main frequency. Reverse to the new band within fifty seconds."
"Pendant reaction?" Su Wanqing stared at the monitoring table.
"The external current is rising, but the temperature is still at a safe level." Lu Zhao was ready to cut off the data flow at any time. "The data flow is not out of control, but the command response is a bit slow."
At this time, Xiao Ran walked in from the side door again, carrying a short knife, frowning and taking out a pocket video card, "The team outside the door is handing over, and they seem to have received a new frequency band prompt. The leader-like man changed the calibration method of the equipment, but it seems that he has not found the synchronization signal of the pendant."
Lin Che placed the prepared fake signal transmitter on the small platform next to the pipe and aimed the main control coil at the ceiling vent. "The transmitting point is set here. The external frequency and the main frequency of the pendant are only half a bandwidth apart. High-level monitoring can't tell the real from the fake at all."
Lu Zhao used the equipment to track the false signal in real time. A broken line jumped on the secondary screen. He said, "The frequency response is effective. Two people in the tracking team turned around and left their posts. They were led to the north of the passage."
Xiao Ran marked the newly discovered route on the equipment map, and whispered to Su Wanqing, "We have prepared all the materials here, and the rest of them will definitely split up again."
Su Wanqing copied down the number of each band and the interference effect that changed in real time into the notebook one by one, "Lu Zhao, how long will the new band last?"
"In theory, the adaptive algorithm can hold up within 20 minutes. Once the local load reaches the upper limit, I will reduce the frequency at any time."
While monitoring, Lu Zhao adjusted the parameters and incorporated the backup obfuscation nodes into the sequence.
Lin Che adjusted the transmitter and continued to update the jamming plan. His voice was a little hoarse. “There was a fluctuation when the false source was released for the first time. It was raised to full gear after 30 seconds. The infected body was basically motionless, but the feedback from the main frequency tracker was raised.”
Su Wanqing took out the backup recorder and said, "I'll record the whole process. If there is any abnormality in the data of the pendant, stop it immediately."
At the other end of the equipment table, the girl with a childish voice huddled in a chair, her eyes slightly red, and her breathing becoming noticeably short.
She had a blanket wrapped around her hands, clenched so tightly that her fingertips began to turn white.
"She's not in the right condition." Lu Zhao raised his chin towards Lin Che while processing the data. "She's slow to react. She said before that she was uncomfortable with low temperatures. Now she can't even open her eyes."
Lin Che walked over quickly and turned down the signal strength. “The interference from the pendant is too strong. It will definitely have a multiplied effect on her.”
Su Wanqing looked at the girl, "Are you okay? Do you want to rest?"
The girl swayed a bit and said softly, "I feel dizzy and I hear... noise in my ears."
Lu Zhao put down the tools in his hand, took out the emergency sedative, read the instructions again to confirm the dosage, and then injected the girl intramuscularly. "Calm down for now. You don't need to talk or move now."
Xiao Ran put the remaining backup paper copies into the isolation bag and said, "Stop the experiment for a while. The main equipment and main data have been backed up."
Lin Che temporarily lowered all the bands to the lowest level and said, "Restore the default signal. I will raise the false transmission point for another ten seconds to give the rebels enough of an illusion and then close it."
The girl slowly loosened her hands that were holding the blanket, lowered her head and leaned against the sofa, her face pale.
Lu Zhao confirmed that the pulse and breathing were stable, and said to Su Wanqing: "Band adjustment is risky, and girls can only bear it. Let's not do large-scale experiments again."
Su Wanqing didn't say anything, just took the clean gauze and gently wiped the girl's forehead.
She cleared the wires and debris on the lab table. "The experiment is suspended immediately. Put away the pendants and do not let the data leak out. From now on, all extreme tests will not involve girls."
Lin Che locked the remaining energy of the false signal point. "Half of the tracking team's signal has been distorted, and the main control team is still wandering around the ventilation shaft in the south area."
Lu Zhao reset the main frequency of the pendant to zero again and disconnected all interfaces.
The device status returned to physical isolation mode. He looked at the time table in the hall again and said word by word: "The external tracking device will not lock our origin again in the short term. The rebels' accuracy has dropped to the margin area."
Su Wanqing tapped the notebook and shifted her attention to the daily protection process.
"Check the girl's physical condition every fifteen minutes, and add a set of spare medicines. I'll keep an eye on the band changes."
Lin Che completed the last step of the search and isolated and archived all the abnormal signal feedback tables.
The room fell silent, leaving only the tail-end hum of equipment and the occasional hum of programs.
Xiao Ran put his weapon on his back again, walked to the door with the updated reconnaissance data, and combined the channel movements and signal disturbance map together.
"The rebel main control will advance two more steps, but the main force has been diverted by your plan. We have more than three minutes left."
Su Wanqing simply nodded and assigned their respective tasks. She sealed the pendant into the isolation jar, affixed the code, and then locked the jar into her backpack.
The data record book that had been cleaned up on the laboratory bench was quickly closed.
The naughty kid was sitting on the sofa, his eyelids still drooping and he was almost falling asleep.
After checking the vein condition, Lu Zhao put the remaining sedatives and emergency kit into a small box and handed it to Su Wanqing.
"Only minimal intervention is allowed and the status of girls must be a priority."
Lin Che cleaned up the console and locked up all the data backups.
He followed Su Wanqing quietly without saying a word until all experimental operations were stopped, then he confirmed the team's next evacuation route again.
Xiao Ran waited for a while and said, "The north side of the well has been arranged. As long as the opponent's tracking misjudgment stops for a little longer, we can escape unscathed this time."
Su Wanqing flipped a page in the notebook without wasting a minute. She wrote down each adjustment in order, put it into a special archive, and checked it word by word on the band detail checklist.
