Section 1 Prologue: Operation Code C076

Time: 23:55:42, wind direction: northwest, deflection: 3.2.

Setting down his mechanical watch, the unshaven man pulled a dark gray sniper rifle from his backpack, adjusted the scope, loaded it, and aimed the crosshair at a building ahead. He glanced at it, seemingly confirming his aim, then pulled out a cigarette, lit it, took a deep drag, exhaled, and pressed the communicator on his earpiece.

“承” means “position”.

He was concise and to the point, because there was really no need for unnecessary words. This was a serious mission, and the usual playful banter was inappropriate. The other party had known him and worked with him for a long time, and understood this as well.

The brief message was instantly transmitted to the other end of the earpiece. Li Cheng opened his eyes, glanced at his watch, and then pressed the communicator to respond.

"Point B has been reached."

I looked up, my gaze drifting slightly past the windowsill to two people smoking and chatting on the balcony of the building across the street. In the dim light, their voices were barely audible, only their dark red cigarette butts remained conspicuously visible.

"Balcony D, two; Entrance No. 2 downstairs, one."

After another brief and rapid report, Li Cheng continued to crouch low, hiding below the windowsill. His breathing almost completely ceased, as if he had become one with his surroundings. It was likely that unless one looked directly at him, even standing right next to him, one would not notice his presence. In fact, it was precisely in this way that he was able to monitor his target from just one building away.

On the rooftop, the man stubbed out his cigarette, closed his eyes, and seemed to be analyzing the information he had just received. Not long after, he opened his eyes and made another communication.

"Tohsaka".

The man stopped after being called by name and waited for the other party's reply.

"Ambush point A2 has been reached."

This time, the voice was extremely low and suppressed; if the man hadn't had exceptional hearing, he probably wouldn't have heard it at all. This was understandable; responding in such a low voice was enough to indicate that the other person was deep inside enemy territory.

“On the roof, three people. Besides the two on regular patrol, the third one didn’t move near Gate B. He’s in your blind spot.”

"Mark the angle," the man said without hesitation.

"..." The other end remained silent.

After a pause of a second or two, the man frowned, sighed almost imperceptibly, and then said, "Could we do this without alerting the infiltrators?"

“Sure, balcony B on the 6th floor is in their patrol blind spot,” the answer was much more straightforward this time, “but you can only go up to the 4th floor at most.”

"enough."

He then took out a small metal box from his backpack, shook out a mint hard candy, and bit into it. He pointed his gun at the two patrolmen chatting on the opposite rooftop, his eyes gradually sharpening.

"Make sure you reach the area directly above the meeting point, and then communicate upon arrival."

"learn."

Communication failed again, but the man was now completely focused. He stared coldly at the people on the opposite building, as if they were already dead.

The wind gradually subsided, and there wasn't a sound to be heard on the rooftop. In the quiet environment, it seemed like an empty place. Similarly, the third-floor balcony of this abandoned building, and the corridors and staircases of the building opposite, were all quiet, like a deserted wasteland where no one lingered.

Sparsely populated, utterly deserted, and utterly silent.

"Arrived, 4th floor living room, 12 seconds until the next patrol shift."

call--

With a long exhale, the man broke the silence, raised the gun in his hand, and spoke calmly, word by word.

"Execute Plan C. Get ready. I'll count to three."

"three--"

Li Cheng, who was hiding on the balcony, silently got up, half-squatted down, and his shoe quietly pressed down on a pebble under his feet, slowly crushing it into powder.

"two--"

The young man patrolling the fourth floor yawned as he strolled down the corridor. The path ahead was quiet, without any strange sounds.

whoosh-

Instead of "one," a gunshot rang out, so faint it was almost imperceptible to the average person. The moment the first person on the roof turned his head, it pierced the second person's forehead. But to the other two, it was an incredibly loud clarion call.

His feet sank into the concrete, and a faint cracking sound could be heard. Li Cheng leaped up, soaring from the balcony towards the building opposite. The two people who were chatting looked up in surprise, only to see a dark shadow rushing towards them. Immediately following was a body lifted off the ground, its throat gripped. The iron grip tightened in an instant, and after a slight cracking sound, the two lifeless bodies were gently placed on the ground.

The second person on the roof was still falling, his body arching backward, gradually approaching the ground. What seemed like a slow movement was enough for the man. He whispered a spell imbued with magic, and his consciousness accelerated in the next instant. The person whose head had been pierced, falling, appeared in slow motion before his eyes.

Click—snap—

This is the echo of the spent cartridge being ejected from the chamber, a long and melodious echo.

As he turned the gun, before the first man's smile could fully fade to confusion, another bullet, accompanied by a spark, flew out. This shot entered the side of his head and exited just outside his ear. Two splatters of brain matter landed one after the other, slowly, then quickly. The man's breathing remained steady, and the gun moved once more.

pat!

The sound of bodies falling to the ground startled the third person by the door. He didn't need to step out of the blind spot; from this vantage point, he could see the two already dead. But a soft exclamation and a footstep were loud enough for the watchful Grim Reaper.

whoosh-

The metal bullet disappeared into the night, piercing through the gray wall. Just as the man behind the wall turned around, the bullet pierced his left eye, bringing with it white and red liquid, which quickly turned black and stuck to the ground.

The man who had done all this chewed the mint in his mouth, letting the cool sensation spread across his tongue, before speaking into the communicator:

"The roof has been cleared."

Almost at the same time, Li Cheng jumped off the balcony.

The wind howled past his ears, then quickened. Li Cheng shifted his position as he fell, his arms taut, fists clenched, before crashing heavily to the ground. The two guards on the ground hadn't even had time to react before being struck on the head by this falling punch. With a "crack," their skulls caved in, their eyeballs popped out and hung from their faces, trickling with fluid.

The person guarding the other side only heard two muffled thuds. When he turned around, he saw a dark shadow suddenly rush in front of him. Before he could even shout, a large hand grabbed his neck and squeezed hard. With the sound of bones cracking, his terrified and distorted expression froze.

"Clear the ground."

"Only about 0.2 seconds slower," Li Cheng said calmly in the communication.

A dazzling light bursts forth in the next second.

A violent explosion erupted on the third floor of the abandoned building, tearing and blowing away the fragile walls. Panic-stricken shouts and screams could be heard from inside, along with other, more intense sounds of battle. Three seconds later, the communication system rang again.

“The ‘displacers’ have been apprehended, and two people are fleeing downstairs.”

Li Cheng turned around and heard hurried footsteps inside the building. Not long after, two boys who looked no more than sixteen or seventeen years old rushed out of the stairwell in a disheveled state, running away from the building with terrified expressions.

"A child this age would actually join this kind of gang?" Li Cheng was slightly taken aback, and his movements involuntarily slowed down. At the same time, the two young men who had noticed Li Cheng blocking the exit reacted immediately. One of them quickly retreated and fled towards another exit, while the other rushed forward and threw a powerful punch at Li Cheng. In the darkness, the fist of the man even reflected a faint light.

Instead of retreating, Li Cheng advanced and caught the punch. With a dull thud, Li Cheng's legs slid back slightly before he regained his balance.

Level 2 enhanced superpower? For his age, reaching that level is quite an achievement. If he had followed the right path, there's no reason he wouldn't have achieved great things.

The young man whose fist had been blocked glared fiercely. He used his free hand to pull out a knife from his body and stabbed Li Cheng in the abdomen.

Unfortunately, this is the path I chose.

A moment's hesitation turned into indifference as the boy stabbed him mercilessly. Knowing the cruelty and ruthlessness of this superpowered criminal group, he would not easily soften his heart just because his enemy was young.

The fingers that had gripped the other's fist suddenly tightened, and with the sound of bones cracking, the boy screamed and fell to the ground. The knife he was holding also fell to the ground, and the hand that Li Cheng had grabbed earlier was twisted into an irregular shape.

The screams stopped abruptly the next moment as Li Cheng grabbed the man's neck and snapped it in one swift motion.

"Empty the room and ensure all members are killed."

It was at this moment that a cold, clear voice came through the communication, quite different from the voice that had been deliberately lowered earlier.

"One of them ran away from the first floor, Emiya. He ran from the direction of Exit 3."

Li Cheng immediately reported that it wasn't that he couldn't catch up with the other party. However, compared to the trouble of a chase, he preferred to rely on his companions at higher ground.

whoosh-

A barely perceptible sound swept across the burning, dilapidated building, followed by a running boy who silently collapsed to the ground.

Annihilation complete.

The man on the roof put down the still-smoking gun and pulled out a semi-transparent smart device that resembled a mobile phone.

Operation code name: C076, completed.

With his gun slung over his shoulder and his bag in hand, the man stood up and left, not glancing back at the still-burning building. He wrote his final summary report on the mission briefing:

Encountering strong resistance, they were forced to fight back in self-defense and killed 26 people.

Boom—

With a loud bang, the burning area of ​​the building began to collapse.

Number of people captured alive: 0.

Section 2, Chapter 1: The Moment of Fateful Encounters

In early spring, the climate in this long and narrow island nation is still somewhat cold.

The young employees passing by were whispering amongst themselves, occasionally glancing over. Their expressions held curiosity, fear, and disgust, but these wouldn't cause any trouble; they'd long since grown accustomed to it.

Li Cheng's eyes wandered out the window, from the bustling city streets below to the open park not far away, with its cherry blossom-lined paths, and the passersby admiring the scenery. It was slightly boring, but still within acceptable limits, considering they had indeed gone too far this time.

Turning back, the office door of the head of the New Tokyo district remained tightly closed, and the noisy sounds inside seemed to never stop. Unlike him, who was standing outside waiting idly, the deputy team leader inside, his friend Emiya, was facing the wrath of the entire organization's higher-ups.

New Tokyo Ward, a bustling city built on the ruins of the original Tokyo, inherits its name from the past. However, due to the excessive incompleteness of records from the previous era, coupled with the changes brought about by modern technology, it is now a completely different place from that historically renowned city.

Of course, there are still a certain number of relics from the past remaining, such as the criminal gang's hideout that we visited on the last mission, which is located in the ruins of old Tokyo on the edge of the New Tokyo Ward.

It was because of the last mission that their group had encountered a lot of trouble, to the point that they had to come here to be questioned by those high-ranking officials.
