Villain? No, I'll catch up with the protagonist after passing the civil service exam.

With a dull thud, the 30-centimeter-thick polymer radiation-proof composite glass door slammed shut in front of Edogawa. This was a clash of physical science and idealistic causality. In Lu Jingyan's pale blue world of absolute rationality, the flow of time stretched infinitely in that single second as the door closed.

At 0.1 seconds, the titanium alloy gears of the door hinges began to mesh tightly. The airlock emitted a piercing screech as it expelled air, completely sealing off the space. At 0.2 seconds, Edogawa's pupils suddenly contracted. His usually composed and wise facial muscles completely lost control, and he lunged forward like a frightened cat, his shoes leaving a dark rubber mark on the non-slip floor.

At 0.4 seconds, the black causal death energy hovering above the boy's head began to surge violently. A nauseatingly thick black mist tried to frantically escape through the crack in the door. At 0.6 seconds, Lu Jingyan coldly snorted. The power of his words, acting as law, transformed into an invisible barrier, forcefully slamming the death energy back into the glass chamber.

At 0.8 seconds, the boy's small, pale hand slammed hard against the transparent wall. The specially made glass distorted his terrified expression. The ingrained line of reasoning was abruptly stuck deep in his throat. One second later, the magnetohydrodynamic lock closed completely. The four eerie blue isolation indicator lights in the corners illuminated simultaneously.

That mystical curse of bringing death wherever one goes has finally been severed by this completely sealed isolation room. Su Xiaoxiao stared at the magnetic field band detector on the tactical tablet, her eyes wide like saucers, and couldn't help but gasp. The girl's slender fingers swiped frantically across the screen, repeatedly checking several sets of comparative data.

"Captain Lu! This is amazing! The moment the isolation room was closed, the unnatural death fluctuations in this Shinjuku area plummeted to zero!" Su Xiaoxiao excitedly looked up, her ponytail swinging behind her head. "This is simply a miracle in the history of medicine and physics!"

Zhao Tiezhu slung the heavy Gatling gun over his shoulder, the bald, burly man chewing gum with a broad grin that made his fleshy face jiggle. "Nonsense! Lock this troublemaker up, and from today onwards, not only humans, but even stray dogs on the street can live to a ripe old age in peace!"

Bruce adjusted his black-rimmed glasses, the red light on his body camera flashing steadily. The Dark Knight, in a deep, husky voice, added the on-site recording to the operation log. "The commander's physical isolation measures perfectly severed the causal chain of crime. This hardcore approach of eradicating crime at its source is far more efficient than my high-intensity nighttime patrols in Gotham City."

Lu Jingyan completely ignored Edogawa, who was frantically banging on the wall in protest inside the glass room. The man, one hand in his pocket, turned and strode confidently towards the traditional hot spring inn where the incident had occurred. He didn't cross the police line, nor did he put on white gloves to play the role of some famous detective. He simply stood at the entrance, his eyes cold as ice.

"Xiaoxiao, retrieve all the surveillance cameras within a two-kilometer radius of the hotel." Lu Jingyan's voice was calm and devoid of any warmth, as if issuing a routine traffic ticket order. "Activate facial recognition and 3D thermal imaging backtracking, and filter out all moving targets with fluctuating heart rates."

"Bruce, take the portable DNA spectrometer." Lu Jingyan turned his head slightly and pointed to the broken camphor wood door frame on the second floor. "Go to the crime scene and collect all sweat and skin flakes. After collection, cross-reference them directly with the system's database."

This is a one-sided, devastating blow from modern legal technology to traditional detective shows. There are no lengthy deductions, only precise scientific instruments operating at high speed. At this moment, in a corner of the corridor on the second floor of the hot spring inn, the murderer in a kimono is trembling among the onlookers.

The murderer bit his pale lips hard, frantically rehearsing the next part of the script in his mind. How to use carbon fiber fishing line to create a locked room, how to use melted ice as a time-delaying murder weapon. He had even memorized the pathetic lines of kneeling on the ground and crying bitterly after being exposed by the detective.

Unfortunately, Lu Jingyan didn't give him any chance to perform. His little tricks, full of dramatic tension, were crushed by violence. Just ten minutes later, Zhao Tiezhu, gun in hand, strode into the crowd.

"Gotcha, you son of a bitch!" Zhao Tiezhu roared deafeningly. His thick arm shot out like an eagle snatching a chick, forcefully lifting the murderer from the crowd. The murderer was slammed onto the hard stone pavement like a lump of mud.

The silver police handcuffs snapped shut, locking onto his wrist. The sudden arrest left the killer completely bewildered. He stared blankly at the cold metal ring on his wrist, his eyes filled with disbelief, shock, and resentment.

"Wait a minute, officers! Why didn't you even ask me anything?" the murderer screamed in despair, tears and snot streaming down his face. "That secret room mechanism took me three whole years to come up with! Aren't you going to check that fishing line?"

"Don't you want to hear my revenge story? This is an emotional release from my tragic childhood!" the murderer protested hoarsely at Lu Jingyan as he struggled. Being deprived of the reasoning process was more painful than a death sentence.

Lu Jingyan didn't even lift an eyelid, casually signing his name on the electronic arrest warrant. "A perfect trap?" Lu Jingyan sneered, his tone full of disdain and condescending mockery. "The Skynet surveillance clearly captured you throwing away your bloodstained gloves in the back alley ten minutes before the incident."

"The DNA sequencing results extracted by Bruce match your genetic map 100%." ​​Lu Jingyan slapped the arrest warrant mercilessly across the murderer's face. "In the face of high-definition cameras and genetic science, your carbon fiber fishing line isn't even worthy of being used by a forensic doctor to pick his teeth."

"Want to tell a story? Save it for the interrogation room and the lie detector. Take him away!" Lu Jingyan waved his hand impatiently and turned away. Zhao Tiezhu grinned, dragging the still wailing murderer, and strode towards the police car parked on the street corner.

Having solved this tedious murder case, Lu Jingyan walked steadily back to the specially made isolation room. Inside the glass, Edogawa slumped dejectedly on the floor. He had just witnessed Lu Jingyan's brutal crime-solving process, which dealt an unprecedented and devastating blow to his brain, which was filled with classical romanticism of detective fiction.

It turns out that real police officers don't need to listen to a murderer's nonsense, nor do they need to search for an alibi. Lu Jingyan looked down at him, his slender fingers lightly tapping the glass. Tap, tap, tap. The crisp sound of the tapping was like a death knell, striking the boy's heart.

"Did you see clearly?" Lu Jingyan's voice penetrated the communication device and reached the boy's ear. "Solving cases relies on an omnipresent surveillance network and airtight DNA evidence. Not on people like you who go wherever they want, killing innocent people and then stepping over corpses to find clues."

The man's words were like a sharp scalpel, mercilessly dissecting Edogawa's proud identity as a renowned detective. Edogawa trembled, raising his head in defiance and shouting, "But I caught the bad guys for you! I was helping you punish evil!"

"That's because you brought death to the victim first," Lu Jingyan shouted sharply. The power of his words, which carried the weight of law, caused the surrounding air to explode. Edogawa was so frightened that he fell to the ground, his reflective black-rimmed glasses slipping down his nose, and his eyes completely losing their luster.

Lu Jingyan pulled out a detention warrant stamped with a bright red seal and stuck it to the glass. "In the eyes of the legal system, someone with your physique isn't a famous detective. This is a source of mass destruction. I've already contacted the Special Meme Research Center of China Police University; a special plane is waiting."

"From today onwards, you must be isolated for life in the police academy's underground bunker. You will serve as a negative example of antisocial causality disasters, for the freshmen to observe and learn from day and night." Lu Jingyan's lips curled into a cold smile. "The state will provide you with three meals a day; no need to thank me."

As the plane carrying the "Grim Reaper Elementary School Student" took off and departed, the skies over Tokyo seemed to clear up. The bizarrely high homicide rate that had plagued the Metropolitan Police Department for years saw a precipitous drop overnight. Even traffic accidents on the streets miraculously decreased by more than half.

Lu Jingyan sat inside the spacious bulletproof command vehicle. He held a cup of freshly brewed hot tea, quietly watching the streets outside the window return to normal. This legal education trip to the land of cherry blossoms had finally come to a successful conclusion. His tense nerves finally found a moment of relief.

However, this rare moment of comfort didn't last long. The red encrypted communicator on the command vehicle's center console suddenly started flashing wildly. A piercing, highest-level alarm instantly filled the entire compartment, and the red warning lights illuminated everyone's faces, making them appear bright red.

Su Xiaoxiao sat bolt upright, her fingers flying across the keyboard. Her expression turned more serious than ever before. "Captain Lu! It's an S-level encrypted dedicated channel from Interpol headquarters in Geneva! Someone has forcibly breached our highest firewall and sent a distress signal!"

The holographic projector activated instantly. A deep, dark blue 3D ocean map, accompanied by rolling electronic waves, was projected directly onto the center of the carriage. Lu Jingyan put down his teacup, a renewed sharpness of reason rekindling in his dark eyes. He pressed the answer button with his slender fingers, and a desperate cry came from the communicator.

Tokyo has regained its security. The International Shipping Association (ISA) has issued an S-level distress call: "Land Bureau, a group of pirates with superpowers has appeared in the Bermuda Triangle, paralyzing shipping routes!"
