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

Upon arrival at their destination, Battalion Commander Wang led them into a rather peculiar-looking house.

The room is about 100 square meters in size and is square in shape. The walls are made of thick, solid bricks, and the ceiling has a special wooden structure, making the whole room very sturdy and soundproof. The room is empty and has no furnishings.

Just as everyone was wondering why the competition venue was chosen here, several of Battalion Commander Wang's subordinates brought in some equipment, including a stand and a 70-inch screen. Then, someone else brought in a metal box, which, when opened, contained eight well-maintained Type 92 pistols and several boxes of ammunition.

Luo Fei gestured for everyone to come forward and collect their guns and ammunition: "One gun and ten bullets for each person."

The group received their guns and ammunition, but they were even more confused—they had the guns and the bullets, but…where were the targets?

Shen Junjie and Li Bin exchanged glances, both frowning. They had originally thought the competition would be held at a professional shooting range, with fixed or moving targets, but they hadn't expected it to be in an empty room without even a target.

Li Bin couldn't help but ask, "Captain Luo, where... are the targets? How can we compete without targets?"

Luo Fei didn't answer directly, but looked at Battalion Commander Wang. Battalion Commander Wang understood and took out a transparent glass bottle from behind him, the mouth of which was sealed with gauze.

Upon closer inspection, everyone saw that the bottle contained dozens of dark, buzzing insects! These insects were larger than ordinary houseflies, with thick bodies and a rather ferocious appearance.

"This is... a cowfly?" Shen Junjie recognized it, a look of surprise on his face.

Luo Fei nodded and pointed to the bottle, saying, "That's right, this is the target for our first match—the bullfly. Adult bullflies are about 15 millimeters long, fly fast, and their trajectories are unpredictable."

Upon hearing this, everyone except Chen Yifan and Wu Peixiong, who both smiled knowingly, was completely stunned! Using a gun to swat flies?! And in this confined space?! How could this be?!
Using these live insects as targets is far more difficult than using traditional fixed or moving targets. It requires not only superb marksmanship but also extremely strong dynamic vision and predictive ability!

Even Shen Junjie, the national shooting champion, had never tried such an extreme challenge! For the first time, his gaze towards Luo Fei was filled with disbelief and astonishment.

Ignoring everyone's shock, Luo Fei picked up a piece of chalk and drew a circle about 1.5 meters in diameter on the ground in the center of the room.

"Everyone, stand in this circle," Luo Fei commanded.

As instructed, everyone stepped into the circle and stood in a neat row, their faces showing tension and uncertainty.

Luo Fei took the glass bottle from Battalion Commander Wang, walked outside the circle, signaled everyone to get ready, and then suddenly ripped off the gauze covering the bottle opening!

Om-!
Dozens of cowflies swarmed out of the bottle opening in an instant, quickly scattering to every corner of the room. Some perched on the walls, while others hovered on the ceiling, emitting an annoying buzzing sound.

Luo Fei then began to announce the competition rules: "The rules are very simple. Chen Yifan, Wu Peixiong, and I will be on one team. The five of you veteran members of the Ganjiang team will be on the other team. All of us will stand inside this circle and are not allowed to leave it. Use your Type 92 pistols to shoot the cow flies inside the room."

One point is awarded for each fly killed. The game ends when all twenty flies in the room are killed, or when all players run out of bullets. The team with the higher total score wins. Understand?

After the rules were announced, the veteran players of the Ganjiang team looked even more grim. This difficulty level was simply outrageous!
At this moment, Wu Peixiong scratched his head and raised a very practical question: "Director Luo, this...this doesn't seem fair, does it? Our team has three people, three guns, and thirty rounds of ammunition. Their team has five people, five guns, and fifty rounds of ammunition. The ammunition supply is different, isn't it?"

Luo Fei glanced at him and said calmly, "We're from the National Security Bureau, so be magnanimous. Winning is the only true measure of fairness."

Upon hearing this, Wu Peixiong immediately shut his mouth and said no more, his eyes filled with trust in Luo Fei.

Hearing Luo Fei's words, Shen Junjie on the other side was unconvinced, even thinking Luo Fei was just being deliberately mysterious and putting on airs. He sneered inwardly: "Hmph, easy for you to say! Just wait and see how you get out of this mess!"

He simply couldn't believe that anyone could hit so many high-speed, swarming flies with a limited number of pistol bullets under such conditions, especially when they were outnumbered. He couldn't wait to see Luo Fei get his comeuppance.

Luo Fei stood inside the circle, looked around the peculiar room, and then explained to everyone, "This room is about thirty meters long. We're standing roughly in the middle right now. So, we're about fifteen meters away from the flies on the opposite wall. If any flies get closer to us later, it'll be a race against time."

Chen Yifan frowned as he looked at the barely visible black dots on the distant wall and asked, "Director Luo, this... this far away, how do we determine whether a shot hit or not? And what if several people fired at the same time, whose responsibility is it?"

Luo Fei pointed to the 70-inch screen set up at the entrance: "Battalion Commander Wang and his men are ready. Look at the screen."

Upon hearing this, everyone turned to look at the large screen. The screen displayed a floor plan of the entire room, with twenty small red dots moving slowly on it, each labeled with a number.

Luo Fei continued to explain, "Commander Wang's men attached a miniature signal transmitter to the back of each cowfly. So the screen can display the location and number of all the cowflies in real time. In addition, multiple high-definition high-speed cameras were installed in the room, which can accurately capture the trajectory of the bullets and the moment of impact."

Even if multiple people fire simultaneously, the system can determine the final kill based on the order and angle of the bullets hitting the target. The match is limited to ten minutes. Any further questions?

Everyone looked at the moving red dots on the screen, then at the inconspicuous cameras in the corner, and shook their heads, indicating they had no more questions. The sophistication of this system exceeded their expectations.

Just then, Luo Fei did something that surprised everyone.

He suddenly stepped out of the chalk circle on the ground, walked to the door, pulled over an outdoor folding chair that had obviously been prepared in advance, and sat down comfortably. Then, he waved to Wu Peixiong inside the circle: "Peixiong, come out too."

"Huh? Me... I'm coming out too?" Wu Peixiong was stunned for a moment, somewhat confused, but still obediently walked out of the circle.

Luo Fei nodded, his tone calm: "Yes, Yifan alone is enough."

Upon hearing this, the expressions of the five veteran members of the Ganjiang team, including Shen Junjie and Li Bin, all changed instantly!

Arrogant! Utterly arrogant!
Shen Junjie's face turned ashen, and Li Bin was so angry that veins bulged on his forehead! They had originally thought that Luo Fei would personally step in, or at least all three of them would go together. Unexpectedly, Luo Fei not only didn't go himself, but also called out another helper, actually intending to rely solely on Chen Yifan to fight against five experienced SWAT veterans?! This was simply a blatant insult and contempt for them!

"Luo Fei! What do you mean?!" Li Bin couldn't help but roar, "Are you looking down on us?!"

Suppressing his anger, Shen Junjie said coldly, "Captain Luo, aren't you being a bit too arrogant?"

Luo Fei sat in his chair, crossed his legs, and had a faint smile on his face. He did not answer their questions, but simply gestured to Wu Peixiong.

Although Wu Peixiong had some doubts, he still put his pistol and bullets back into the metal box next to him without hesitation.

The five players from the Ganjiang team were furious at Luo Fei's relaxed and confident demeanor, as if victory was already in his grasp! They secretly vowed to make this arrogant captain of the National Security team pay the price for his arrogance! To make him lose face!
The game officially begins.

However, everyone soon realized that the difficulty of this competition far exceeded their initial expectations!

In a space of one hundred square meters, there were only twenty flies. Most of them were perched on the opposite wall in the distance or on the high roof, with only a few occasionally hovering and flying in the air.

At a distance of fifteen meters, a fly on the wall appears as a tiny black dot to the naked eye, making it difficult to aim accurately. Moreover, these flies are not completely still; they will occasionally move or suddenly take flight, making their trajectories unpredictable.

In addition, the Type 92 pistol itself has considerable recoil. To accurately shoot at such a small target from 15 meters away while standing is extremely difficult, and even an Olympic shooting champion would probably find it hard to handle!

The members of the Ganjiang team initially tried to aim at flies flying in the air, but quickly gave up and focused on stationary targets that were relatively easier to aim at, such as those on walls and rooftops.

boom!
Han Tongyang was the first to fire. The bullet whistled through the air, striking the concrete of the opposite wall, kicking up a small cloud of dust and leaving a clear crater. However, on the big screen, the small red dot representing the fly continued to move, without any change.

boom!boom!
Immediately afterwards, two more team members fired their guns, but the result was the same; the bullets flew off somewhere, and not a single red dot on the screen disappeared.

boom! boom! boom!
The three men fired at different targets almost simultaneously, the deafening gunfire echoing through the room, filling the air with the smell of gunpowder. Yet, the red dot on the screen stubbornly persisted.

After several rounds of shooting, the five members of the Ganjiang team hadn't even hit a fly! Their faces began to look grim, sweat beaded on their foreheads, and their hands gripping their guns trembled slightly from tension and strain.

Only then did they truly realize how perverse the challenge of swatting flies with a gun truly was!
All eyes were drawn to their ace, national shooting champion Shen Junjie, placing their last hopes on him.

Shen Junjie took a deep breath, forcing himself to calm down. He held his breath, his eyes sharp as an eagle, carefully aiming at a relatively still fly on the wall fifteen meters away. His finger slowly pulled the trigger.

boom!
A gunshot rang out! The bullet struck precisely where the fly was! Everyone stared wide-eyed, anticipating the outcome!

However, the next second, on the big screen, the little red dot representing the fly suddenly flickered, but did not disappear! The bullet almost grazed the fly's body, hit the wall, and the blast wave sent the fly flying, but it did not hit it!

"Hiss..." Everyone let out a sigh of regret.

Shen Junjie's face paled slightly, but he didn't give up and immediately looked for the next target. He saw another fly crawl, and immediately aimed and fired again!
boom!
The bullet missed again! The fly seemed startled and suddenly flapped its wings and flew away!

Shen Junjie's two consecutive failures dealt a significant blow to his confidence. Seeing even their captain struggling, the other team members became even more frustrated and discouraged.

Just then, Chen Yifan, who had not fired a shot, was provoked by Chen Jiawei.

"Hey! You from Guoan! Didn't your captain brag that you could handle it all by yourself? Why are you just standing there watching? Are you scared out of your wits? Too scared to shoot?" Chen Jiawei's tone was sarcastic.

Upon hearing this, Chen Yifan was not angry. Instead, he smiled confidently and turned to look at Luo Fei, who was sitting leisurely watching the battle from the doorway.

Luo Fei gave him a thumbs up and gave him an encouraging and trusting look.

Chen Yifan nodded, took a deep breath, and slowly raised the Type 92 pistol in his hand. His gaze became unusually focused, locking onto a fly in the corner of the opposite wall.

Unlike the others, he didn't rush. Instead, he steadily supported his right wrist holding the gun with his left hand to minimize shaking, while slightly squinting one eye and aiming with his amazing visual acuity and sense of touch.

The room fell silent instantly, all eyes fixed on Chen Yifan. The Ganjiang team looked on with suspicion and scrutiny, while Luo Fei and Wu Peixiong were filled with anticipation.

boom!
Chen Yifan pulled the trigger! The bullet left the barrel!

Because of the great distance, the people could not see whether the bullet had hit the target; they only saw that a small hole had been punched through the cement of the opposite wall.

Almost at the same moment the gunshot rang out, everyone instinctively turned their heads sharply and looked at the large screen at the entrance!

After Chen Yifan pulled the trigger, the gunshot echoed through the room. Everyone held their breath, their eyes fixed on the huge display screen by the door.

However, none of the twenty little red dots representing flies on the screen disappeared!

Chen Yifan...missed the target!

"Pfft!" Li Bin was the first to burst out laughing, then immediately hissed without any politeness, "Tch! I thought he was something special! Turns out he's just all show and no substance! What a show-off!" (End of Chapter)
