Wasteland Survivalist: A Scientific Guide to Post-Apocalyptic Survival

In addition, Gu Lang also removed an IR5118 thermal imaging scope from other guns, which can be replaced on any gun for nighttime combat.

He was slightly disappointed that he hadn't been able to capture a QBU-191 marksman rifle in this operation.

They went back to the corridor and searched several times, but in the end they still couldn't find a silencer or grenade launcher on the body.

Only two Type 92 pistols, a Type 191 bayonet, a tactical light for guns, a QMK-152 prism sight with 3x magnification, and several spare laser pointers and red dot sights were found.

However, there were still some unexpected surprises this time around.

While moving several bodies stacked together, he discovered that one of the men had a four-lens panoramic night vision device on his helmet.

After disassembling the main body along with the external battery compartment, Gu Lang excitedly went outside into the corridor.

After turning on the flashlight and completing the disinfection process, he carefully inspected the items.

The label on the casing indicates that this is a PNVG-18 low-light night vision device.

After stuffing the night vision goggles, along with a pistol, a rifle, and a large amount of ammunition into his backpack, Gu Lang left the pharmaceutical factory satisfied.

On his way back to the vaccine factory, in a great mood, he couldn't resist taking out his new toy to play with.

The thick clouds blocked out the moonlight and starlight, making the deserted city almost completely dark.

Low-light night vision devices lack available ambient light, resulting in poor observation performance.

So Gu Lang switched to a thermal imaging scope for testing, but as he casually scanned the surrounding area, his movements suddenly froze.

In the thermal imaging field of view, four furtive human figures were clearly visible.

He immediately ducked to hide, and then saw the other person sneaking towards the pharmaceutical factory.

Gu Lang put on the headset of the individual soldier communication terminal and whispered an alarm to Li Zheng.

"Something's wrong! Unidentified individuals have entered the pharmaceutical factory."

"Received! I'll be waiting for you at the entrance." Li Zheng's reply was brief and to the point, and the two quickly met at the entrance of the vaccine factory.

Gu Lang quietly launched a thermal imaging drone, and a conspicuous jeep appeared near the medical city.

The heat generated by the engine makes it extremely noticeable in low-temperature environments.

After careful examination, Li Zheng confirmed that this was the fourth car that had escaped earlier.

The other party's return clearly indicates ill intent.

"Very good," a cold fighting spirit flashed in Li Zheng's eyes, "this time it's our turn to be the hunters."

After discussing it, the two immediately decided to wipe out the last four survivors.

"The action plan is as follows," Li Zheng said in a low voice. "I will occupy the high ground on the concrete platform on the right, lock onto the most threatening target with the thermal imaging scope, and suppress it with firepower."

"Understood," Gu Lang nodded, his eyes equally cold. "You create an opportunity for me, and I'll fly over their heads and give them a surprise."

The battlefield situation has reversed; now they are the ones with thermal imaging detection capabilities.

Gu Lang handed over the precious thermal imaging scope, along with the Type 191 rifle, to Li Zheng, whose marksmanship was more accurate.

He quickly retrieved the drone, grabbed a grenade, and secured the grenade grip to the hook with a rubber band.

Then, take off the drone, hover it in front of you, manually pull out the safety pin, and put the grenade into "ready to fire" mode.

This way, as long as the servo is activated remotely, the grip will loosen as the grenade falls.

The compressed spring will immediately push the firing pin, striking the firing cap.

The percussion cap ignites the delay charge, which burns stably for 4 to 5 seconds before finally igniting the main charge inside the projectile, causing an explosion.

After the thermal imaging drone flew away, Gu Lang raised its flight altitude to 150 meters.

At this altitude, even in extremely quiet environments, ground personnel can barely hear the noise of this small quadcopter drone.

With its flight lights off, the drone blended completely into the darkness, becoming virtually undetectable.

The transmitted footage showed that Li Zheng had reached his combat position, lying prone on the edge of the platform, and steadily setting up his rifle.

"I have locked onto my target," Li Zheng whispered.

"Roger that, operation commences."

"Bang! Bang!"

Two crisp gunshots, fired very close together, shattered the silence.

In the thermal imaging field of view, a "heat source" fell to the ground with a thud, its head exploding like a watermelon.

The sudden, precise strike put the remaining three berserkers on alert. They immediately took cover behind a nearby low wall and fired back.

After firing a few more shots, Li Zheng failed to achieve any further results and completely exposed his location.

When enemy bullets hit the concrete platform, he moved to a new location as planned and left the platform.

Just then, the drone controlled by Gu Lang hovered directly above the low wall.

He pointed the camera directly downwards, adjusted its position slightly, and aligned the grenade in the frame with the three "bright spots" below.

Then, the drone is lowered to a height of 120 meters, at which point it takes 5 seconds for the object to fall freely to the ground.

Taking into account the air resistance of the spherical grenade, the descent time should be between 5.5 and 6 seconds.

This allows the grenade to explode in mid-air at a height of 1 to 3 meters, ensuring that the fragments cover the ground area at the most effective angle.

At the same time, maintain sufficient fragmentation density to maximize the damage to enemies lying down or hiding behind cover.

The biggest mistake made by the group of berserkers who launched the aerial attack was that they didn't calculate the altitude properly, causing the grenades to land prematurely, which allowed Gu Lang and his two companions to escape death.

Gu Lang would naturally not make the same mistake twice.

"boom!!!"

The explosion burst forth in the darkness, instantly illuminating the small area, and a complete sphere appeared in the thermal imaging.

The pre-fabricated fragments flew outwards at extremely high speeds, leaving no blind spots for escape.

The three berserkers collapsed to the ground after being hit, struggling to get up again, completely incapacitated.

"Grenade hits target, enemy is incapacitated!" Gu Lang reported the battle situation through his headset.

"Roger that, I'll go finish off the enemy." Li Zheng's voice was devoid of any emotion.

He carried his rifle and charged quickly toward the low wall, his steps steady and swift.

After quickly peering through the probe and confirming it was safe, he then stepped forward.

"Bang! Bang! Bang!"

Three clean, crisp bursts of fire ended the berserker's roar with bullets.

The world returned to deathly silence, with only the smell of gunpowder slowly drifting in the night wind.

The last threatening group of berserkers was also completely eliminated.

With no time to clean up the final battlefield, Gu Lang and Li Zheng immediately returned to the stadium.

Since the reason for the sudden return of the four berserkers is still unclear, there is a possibility that more berserkers may appear later.

The three made a quick decision to leave Taizhou Medical City, a place rife with trouble, overnight, to avoid any unforeseen complications.

Finally, Gu Lang drove the Lynx assault vehicle, using thermal imaging night vision devices for reconnaissance, and led the way.

Li Zheng and Wang Bin each drove a truck to follow in a safe position, transporting supplies and providing support.

Wang Bin injured his left leg and couldn't press the clutch pedal.

Fortunately, one of the trucks was automatic, and after confirming that there were no problems, the three of them officially began their return journey towards the sea.
