A real killer playing a villain; the guy surnamed Zhen in Detective, run!

Forty-eight hours later, in the Mediterranean at night, the diesel engines of smuggling fishing boats sputtered in the darkness, the stench of fish overwhelming.

Lu Yuan climbed out of the bottom watertight compartment, his matte diving suit making him look like a black shadow.

The boat captain was Moroccan; once he took the money, he wouldn't ask any questions.

"We've arrived." The captain pointed to the dark sea. "Ten nautical miles away, behind that reef."

Lu Yuan checked the air pressure valve of the closed-loop recirculator, then turned over and entered the water. The Mediterranean night water temperature was fourteen degrees Celsius, cold.

AP Valkyrie's closed-loop system produces no bubbles, resulting in near-zero acoustic characteristics. Miniature thrusters, close to his right side, propelled him at low power, gliding him into the darkness at 1.5 knots.

Two nautical miles of marker line, the miniature terminal vibrates.

The sonar probes swept in from three directions, and the high-frequency pulses traveled four times faster in water than in air.

The AI ​​system's discrimination threshold is: any target with a volume exceeding 0.5 cubic meters and whose movement pattern does not conform to the marine organism database will be automatically marked.

Lu Yuan cut off the thrusters, his body hovering at a depth of thirty meters, and closed his eyes.

The memories of my past life are precise down to every single parameter. The six transmitters are arranged in a hexagonal pattern, with a beam intersection scanning period of 7.2 seconds, but there is a 6.5-second blind window below 30 meters at the bottom.

In those 6.5 seconds, the effective detection thickness of the sonar shrank to less than three meters.

Lu Yuan adjusted the thruster mode to intermittent pulse, propelling the thruster once every 6.5 seconds, with each pulse lasting no more than four seconds, and remaining completely still for the remaining time.

The paddling frequency is controlled at 0.4 Hz, which is the standard cruising rhythm of a large green sea turtle.

It crawled forward, clinging to the edge of the seabed and the reefs.

……

In the underground monitoring room on the island, the radar operator stared at the feedback screen of sonar node number three, the cursor jumping once on the baseline.

Very slight, a blurry speck of noise flashed for less than half a second at a depth of thirty meters.

He pulled up the AI ​​analysis map, and the system provided a matching result: a large group of green sea turtles passing by, creating an ocean current eddy. The confidence level was 91%.

The radar operator muttered, "The sea turtles swam deep enough tonight."

He pressed his right hand on the secondary alarm button and paused for three seconds.

Ninety-one percent, while the standard release threshold is over eighty-five percent.

Let go and move on to the next set of data.

At this moment, Lu Yuan's fingers had already gripped the black reef at the mouth of the wave-breaking cliff on the leeward side of the island, and he climbed up.

The diving gear was removed and stuffed deep into the rock crevices. The liquid nitrogen tank, EMP generator, military knife, and steel wire were all transferred to the tactical vest.

On the mudflats, a high-frequency warning popped up on the micro-terminal, and Lu Yuan lowered his body and pressed himself against the back of the boulder.

Ahead lies a jumble of rocks, estimated to cover an area 200 meters in depth. There are pressure-activated smart landmines on the ground, their fuses triggered by pressure exceeding 40 kilograms.

Microwave detectors were mounted on both sides of the cliff face, with the transmitters and receivers overlapping. The human body has a very high reflectivity in the microwave band due to its water content, making it impossible to force one through.

Even more troublesome were the living creatures. Two sentries approached from the western edge of the rocky forest, each leading a mechanical dog. These dogs had titanium alloy skeletons, infrared pupils, and scent sensors twenty times more sensitive than real dogs.

The mechanical dog suddenly turned its head towards Lu Yuan, its metal joints clicked twice, its gait switched from patrol mode to tracking mode, and the sampling frequency of its infrared pupils increased.

Lu Yuan's right hand was already gripping the switch of the liquid nitrogen tank.

If the robotic dog takes another step forward, the sentry will receive a lock-on alarm.

With no other choice, the canister was pointed at himself and the rock surface within a three-meter radius, and the valve was fully opened. Nitrogen gas at -196 degrees Celsius was atomized and sprayed out, and white smoke covered the entire area within two seconds.

The surface temperature plummeted from 36 degrees to 11 degrees, the same as the reef, the infrared signature disappeared, and the microwave reflectivity was reduced by 70% after being covered by the ice.

The robotic dog's infrared pupils were aimed at the pile of "stones," and after calculating for 1.3 seconds, the target was lost.

The two sentries looked down at their wristwatches and read, "Target has disappeared; likely triggered by environmental factors."

The instant they lowered their heads, Lu Yuan leaped from above the rocks, gripping a tactical steel wire in each hand. The momentum of their fall, combined with the torque from their twisting arms, caused the steel wires to slice into their cervical spines from under their bulletproof helmets.

Not a single sound leaked out!

The two robotic dogs lost their signal connection with the operator and automatically entered standby mode, sitting in place.

Lu Yuan pressed the right index finger of a nearby corpse against the fingerprint sensor area of ​​the communication terminal, and an electronic receipt stating "All is normal in the West District" was issued.

The operator at the monitoring center noticed a frame freeze in the feed from camera position three but didn't pay much attention to it.

Lu Yuan dragged the body into a crevice, removed the bulletproof plate and hung it on his chest, then stepped into the rocky forest.

The trigger threshold for pressure-activated landmines is 40 kilograms of concentrated pressure. Lu Yuan's weight plus equipment exceeded 90 kilograms, so he used a very primitive method: stepping on stones.

Each step landed only on the exposed, large rocks, never touching the surface sand; the mechanical dog's patrol route proved the existence of a safe path.

After a three-minute walk through the rocky forest, a cluster of buildings comes into view, with gray concrete walls and a sign that reads "Seawater Desalination Plant." High-powered ventilation fans are humming away.

The access control system uses both iris and fingerprint verification. Lu Yuan could fool the fingerprint layer with the missing finger of the hidden sentry, but the iris required liveness detection, so he couldn't use the main entrance.

The ventilation ducts extended from the roof, and the grilles were fixed with stainless steel bolts. Lu Yuan used his military blade to unscrew four bolts and crawled into the duct.

After crawling forward fifteen meters, a sound came from the passage below: the low-frequency vibration of the generator set.

The grille was removed and placed on the ground. The moment my feet touched the ground, the camouflage panels on either side of the ceiling suddenly popped open.

Two six-barreled machine gun turrets descended from the hidden compartment, and the infrared tracking head locked onto his heat source. At the same time, the security door on the left was kicked open, and four people filed out.

The exoskeleton tactical armor and hydraulically assisted joints allow them to move faster than normal humans, and the large-caliber shotgun's drum magazine holds twenty buckshot rounds.

"Fire!"

The hail of bullets was relentless, sending concrete debris flying from the load-bearing columns. The machine gun turret rotated at a rate of three thousand rounds per minute, and the crossfire cut the entire passage into a death zone.

Before the first shot rang out, Lu Yuan had already lunged towards the shadow of the generator set to the side. The shotgun shell struck the spot where he had just stood, leaving a crater the size of a bowl in the ground.

The passage was less than four meters wide. A machine gun turret blocked the front, while four heavily armed men pushed up from the flank. The hydraulic arms of their exoskeletons allowed them to control the recoil with one hand while simultaneously throwing flashbangs with the other.

Lu Yuan was pinned behind the generator, with shrapnel constantly striking the generator's metal casing.

He pulled an EMP generator out of his vest, the modified magnetron buzzing in his palm, the indicator light changing from yellow to green.

Once charging is complete, the generator is thrown towards the center of the channel.
