Solving the case: Combining the police dog's olfactory genes at the beginning

"Watch out! Heavy machine gun!"

The child, with sharp eyes, immediately shouted a warning!
Before he finished speaking, the machine gunner in the first pickup truck had already pulled the trigger!

"Thump thump thump thump thump—!!"

The dull yet penetrating roar of the Type 85 heavy machine gun suddenly rang out! Like the drumbeat of death! Dozens of large-caliber bullets, capable of tearing through light armor, swept towards the rooftop where Luo Fei had been standing and the area where the child and Qinglong were hiding, like a metal storm!

"Hide!"

The children's faces changed drastically; they dared not show their faces, cowering tightly behind their cover. Bullets struck the concrete bunker and walls, blasting open craters the size of bowls, sending rubble and debris flying like a torrential downpour, filling the air with smoke and dust!

Meanwhile, another pickup truck made a sharp turn, its large gun barrel pointed directly at the glass of the hospital's main entrance!
"Thump thump thump thump—!!"

Another burst of ferocious gunfire erupted!

The hospital's beautiful glass doors and the walls next to them shattered instantly like paper in the face of heavy machine gun bullets!
Countless shards of glass and chunks of cement flew inwards!
Teacher Huang and Sister Tianji, who were guarding inside the door, sensed something was wrong as soon as they heard the machine gun fire. They quickly pulled the children and the rescued people to the ground and sought shelter from sturdy load-bearing pillars.

Bullets whizzed overhead, leaving the hall in a mess, with debris flying everywhere and screams erupting from the crowd!
Standing on the rooftop, Luo Fei listened to the muffled thuds of bullets hitting the floor beneath his feet and the explosive sounds coming from the direction of the hospital gate. His eyes instantly turned icy cold.

He saw the two pickup trucks attacking his team and the hospital where the children were hiding!

Without hesitation, he immediately picked up the heavy Barrett sniper rifle in his hand, leaped onto the railing at the edge of the roof, and stood as steady as a rock! His sharp, hawk-like eyes instantly locked onto the two pickup trucks below that were still spitting fire!
There's no need for careful aiming; with the Eagle Eye ability, the location of the fuel tank is as clear as if the bullseye had been drawn!

He calmly pulled the trigger!

"boom!!!"

The Barrett's terrifying gunshot, comparable to a small cannon, rang out! A large armor-piercing incendiary round flew out of the barrel at an astonishing speed and accurately penetrated the fuel tank of the first pickup truck!
Almost simultaneously, Luo Fei swiftly pulled back the bolt, ejected the spent cartridge, loaded a new round, slightly moved the muzzle, and pulled the trigger again!
"boom!!!"

A second, deafening gunshot rang out!

The first pickup truck was hit and its fuel tank burst open, instantly turning into a huge fireball!

The scorching flames and shockwaves engulfed the machine gunner and driver on the vehicle, turning them into charred remains before they could even scream!
Immediately afterwards, a second pickup truck followed suit. Amidst a deafening explosion, parts flew everywhere, and the blazing wreckage illuminated half the square like a torch!

Two bursts of fire and explosions silenced the clamor of the entire battlefield!
Luo Fei stood on the edge of the fifty-meter-high rooftop, holding a Barrett rifle that was still emitting blue smoke, like a war god descended to earth.

He activated his Eagle Eye ability, gaining a clear view of the entire K2 park's layout.

He could clearly see that, in the directions of zones B, C, and D, a large number of guards were converging on zone A, towards the hospital, which was the central point, just like streams of filthy water!
"trouble."

Luo Fei whispered something and jumped back onto the roof from the railing.

His gaze swept across the room and spotted a black canvas bag left behind by the dead sniper. Upon opening it, he found dozens of bright yellow Barrett sniper bullets inside.

"nice one."

Luo Fei accepted it without hesitation.

He quickly reloaded the Barrett, then picked up the weapon again and aimed it at the guards downstairs who were still trying to attack, stunned by the pickup truck explosion.

"boom!"

The Barrett's characteristic deep, resonant thud rang out once again!

Downstairs, a guard who was firing an AK-47 toward the hospital entrance had his head smashed like a watermelon and vanished instantly!

A column of blood several meters high spurted from the headless neck, and a red and white paste-like substance splattered all over the face and body of the companion next to it!
The guards nearby were terrified, their faces covered in warm blood and brain matter. They stood frozen in place, their legs trembling violently, their crotches instantly soaked, and a strong stench of blood filled the air!
"Ghost... ghost!"

He let out a heart-wrenching scream and turned to run away.

But Luo Fei didn't give him a chance.

"boom!"

Another bullet struck, and the terrified guard's upper body was shattered by the terrifying kinetic energy, collapsing to the ground in a bloody mess.

"boom!"

With the third shot, another guard who was trying to find cover was blown to pieces, along with the low wall he was hiding under!

On the rooftop, Luo Fei was like a ruthless, targeted elimination machine. Every time Barrett roared, it would inevitably take the lives of one or even more guards, and their deaths would be extremely gruesome!

The Qinglong, Wuming, and Xiaohai, who were struggling downstairs, heard the familiar and reassuring loud gunshots overhead and saw the enemies on the other side falling one after another as if being harvested by an invisible scythe, their deaths horribly. Their morale was immediately boosted!

"It's Fei! Fei is on the roof supporting us!"

The child shouted excitedly.

"Damn it! With Fei-ge holding the gun, what are we afraid of?! Brothers, follow me and charge out, kill these bastards!"

With a roar, Qinglong took advantage of the enemy's fear and trepidation as they were suppressed by the Barrett, and was the first to rush out from behind cover with his gun!
The nameless man and the child followed without hesitation!
Under the cover of the deafening roar of Barrett's gunfire, the three men were like tigers released from their cages. Their automatic rifles spat fire, sweeping away the stunned and retreating guards, turning them into sieves!

Luo Fei calmly fired from the rooftop, quickly emptying a magazine.

He was preparing to reload when he noticed that the remaining enemies downstairs had learned their lesson and were hiding in blind spots of buildings or behind vehicles, no longer daring to expose themselves to his gun.

"Would hiding really help?"

A disdainful sneer appeared on Luo Fei's lips.

He did something that left everyone downstairs who saw it, whether enemies or his own teammates, dumbfounded and speechless!

He carried the heavy Barrett rifle in one hand, took a few steps back, then suddenly accelerated and leaped from the edge of the rooftop! He actually jumped like a cannonball from the fifty-meter-high main hospital building to a nearby business annex building that was only about thirty meters high!
"Holy crap! Fei-ge!!"

The Azure Dragon, who had just rushed out ready to make a big splash, looked up and saw this scene. His eyes almost popped out of their sockets, and he couldn't help but swear.

Inside the business building, some "piglet" who were secretly watching from the windows also witnessed this scene that was beyond their comprehension. They all opened their mouths wide enough to fit an egg, their minds completely blank.

Does this person... can fly?!

"Boom!!"

Luo Fei's figure crashed heavily onto the roof of the business annex building like a meteorite! The enormous impact seemed to shake the entire roof, and spiderweb-like cracks spread across the concrete floor slabs from his feet, stretching over a meter in length!
Amidst the billowing smoke and dust, Luo Fei acted as if nothing had happened, swaying as he stood up, even taking the time to brush off the dust that had splashed onto him.

He gave the enemy no time to react, quickly set up his Barrett, and began another precise sniping operation from the new, unexpected firing angle of the annex!

"Bang! Bang! Bang!"

The muffled gunshots, like the death knell, rang out from a new direction.

Those guards who thought they had found a safe blind spot didn't even realize where the bullets were coming from before their heads or upper bodies exploded instantly! In just over ten seconds, more than twenty guards met their demise without even realizing it!

Taking advantage of the opportunity, Qinglong, the child, and the others rushed to the area near the annex building, only to find headless corpses and broken limbs scattered all over the ground. They were amazed by the terrifying power of the Barrett and Luo Fei's incredible marksmanship.

"Is this even a gun? It's practically a demolition tool!"

Qinglong looked at a corpse that had been broken in half and clicked his tongue.

"Brother Fei's marksmanship... is truly unmatched!"

The child also sincerely admired him.

The remaining enemies were utterly terrified. They finally spotted the sniper on the rooftop, who was like a grim reaper, and screamed in terror as they desperately retreated to the farthest corners or deeper into the buildings like headless flies, never daring to show their faces again.

Luo Fei watched from the rooftop of the annex building as the enemy retreated into their shells, his brow furrowed slightly.

He once again did something extremely audacious!
He picked up the Barrett rifle and jumped off the roof of the annex, which was more than 20 meters high!

"He jumped again!!"

The "piglet" in the business building exclaimed in disbelief once again; the scene they witnessed today had completely overturned their worldview.

"Oh!"

Luo Fei landed steadily on the hard cement ground below, making a heavy impact sound, and his feet even stomped out two shallow craters in the ground.

He casually dusted off his combat uniform, picked up his iconic Barrett sniper rifle, and strode confidently toward the Central Hospital, as if he had simply jumped two steps.

Teacher Huang and Sister Tianji, who were guarding the broken gate of the hospital, peeked out from behind their cover when they saw Luo Fei return, their faces still showing shock.

"Brother Fei, are you alright?"

Teacher Huang quickly asked.

"I am fine."

Luo Fei waved his hand, glanced at the messy hall, and quickly gave the order.

"Teacher Huang, you stay at the hospital to ensure the safety of the children and everyone else! Tianji, Rose, you two go out now and work with Qinglong and the others to completely wipe out the remaining enemies in Area A. Be quick!"

"understand!"

Without any hesitation, Tianji and Blood Rose immediately picked up their weapons and nimbly rushed out of the hospital gate to join the battle outside.

Luo Fei walked into the hospital, looked at Teacher Huang, and spoke with a hint of concern.

"Old Huang, how are the children? Are they all alright?"

Teacher Huang quickly answered.

"Don't worry, Fei-ge, the children are all fine. They were just a little frightened. We've settled them on the fourth basement level, where they're very safe."

Luo Fei nodded, and was about to say something more when suddenly, his keen ears caught a strange sound—a dull and continuous "thump-thump" sound coming from the direction of the east gate of the park, as if something heavy was violently pounding on the gate!

"Ok?"

Luo Fei's eyes sharpened, and he immediately turned to look in the direction of the East Gate, his brows furrowing tightly.

"What's that sound coming from Dongdaemun? Is someone banging on the door?"

He listened intently for a moment, and the crashing sounds did not stop; instead, they became more frequent and heavy, interspersed with faint shouts and the roar of engines.

Luo Fei's heart sank, and he instantly understood.

"It's reinforcements! Su Qidu or Po Jun's reinforcements have arrived!"

He said in a deep voice, his tone carrying a hint of solemnity.

"We've cleared out the guards at Dongdaemun, so they can't get in and are trying to force their way in!"

Upon hearing this, Teacher Huang's expression also turned grim.

"Brother Fei, what should we do?"
If they rush in, their firepower will definitely be concentrated on the main gate first. With so many children in our group, it will be difficult for us to break out!

Luo Fei took a deep breath, forcing himself to calm down, his brain racing.

The current situation is indeed tricky. Leading more than twenty children who have no ability to protect themselves, the chances of breaking through the enemy's heavy encirclement are extremely slim, and the children are likely to be injured or killed in the firefight.

In an instant, a thought became clear in his mind—he couldn't go out, at least not now!

"Change the plan!"

Luo Fei made a quick decision, a resolute glint in his eyes.

"Let's not leave yet! Let's use this K2 park as our temporary base! We'll hold out here using the buildings and walls! Once we've cleared out the external threats, we'll figure out a way to safely send the children out!"

He glanced out the window. Although most of the guards in the park had been eliminated, sporadic gunfire indicated that the battle was not yet over and that his own forces were severely understaffed.

"We don't have enough manpower. It's unrealistic to expect the seven of us to protect such a large park."

Luo Fei's gaze swept towards the huge business building not far away, where there were still thousands of imprisoned "piglet" inside.

"We need to mobilize all available resources!"

With that in mind, Luo Fei no longer hesitated and quickly explained to Teacher Huang.

"Old Huang, you guard this place, I'll be right back!"

After saying that, he picked up his gun and strode towards the business building.

Inside the business building, chaos reigned. The intense gunfight, explosions, and the miraculous arrival of Luo Fei and his men had already terrified the "piglets," management, and thugs in the building.

When Luo Fei walked in, exuding a menacing aura and carrying that conspicuous Barrett rifle, everyone in the hall instantly focused their attention on him.

Those thugs and managers who usually acted arrogantly were terrified, their faces pale, trembling as they huddled in a corner, afraid that this killing god would notice them.

The other "piglet" looked at him with a mixture of fear, curiosity, and a faint hope.

Luo Fei walked to the center of the hall, looked around, and spoke loudly, his voice carrying clearly throughout the entire hall. (End of Chapter)
