My sister, whom I raised, has turned evil after faking her death for three years.

With the assistance of both families, the investigation into the accident was conducted by Captain Zhang, a veteran criminal investigator from the Beicheng City Public Security Bureau's Criminal Investigation Detachment, who personally led the investigation. The investigation was completed in less than a week.

Every step of the truth is cold and precise, like a scalpel, cutting out every frame of that rainy day clearly.

Cui Jiayi sneaked into a freight parking lot near the main road of Beicheng on the evening before her birthday.

She chose a heavy truck fully loaded with building materials. The driver was a man in his fifties who was eating a boxed lunch in the cab.

She knocked on the car door, used the knife she had taken from Liu Liya's car to force the driver to drive a short distance east of the city, then killed him on a secluded side road and dumped his body on the main road in the north of the city.

The sky was overcast that day, a downpour was imminent, and visibility was extremely low. A passing car driver failed to notice the body lying across the road in time through the rain and fog. After running over the body, he thought he had hit someone and, in a panic, stopped his car in the middle of the road.

One car after another braked to a stop, bringing the entire main road in the north of the city to a complete standstill.

This was the real reason for the massive traffic jam, and also the root cause of why the other car responsible for protecting Su Qing and Jiang Ran was stuck on the road and unable to arrive in time.

Cui Jiayi drove the heavy truck along a route she had scouted beforehand, making her way to the only road leading to the east of the city.

She chose a crossroads with a wide view but little traffic due to the weather, parked the car in a secluded spot at the intersection, turned off the engine, and waited quietly.

She waited for a very long time, so long that the rain completely blocked the car windows, so long that her fingers gripping the steering wheel began to stiffen and tremble, not because of the cold, but because of excitement.

Then she saw the black sedan slowly approaching from the rain, slowing down at the intersection to prepare to turn.

She slammed on the gas, adjusted the direction, and crashed straight into it.

  

The dashcam recorded the entire collision. The heavy truck, like an out-of-control steel behemoth, broke through the rain and its front end precisely struck the right side of the rear seat of the sedan.

Seconds before the impact, the footage shows Su Qing lunging at Jiang Ran, completely covering her with her body.

At the moment of impact, Su Qing's body jolted violently, her back slamming into the dented car door, but her arms protecting Jiang Ran did not loosen even slightly.

The cameras outside the car recorded everything that followed.

Cui Jiayi staggered out of the truck's cab, knife in her hand, and walked towards the mangled car. She tried to kill Jiang Ran, but was stopped by the seriously injured Su Qing.

Su Qing grabbed the blade with her hand, and the blade pierced through her palm.

Cui Jiayi dragged her out of the carriage and threw her to the ground. She was covered in blood, her white dress was stained red, her left arm hung down unnaturally, and blood gushed out from the wound on her chest with every step she took.

But she still stood up, and after Cui Jiayi raised the knife to stab her in the chest, she grabbed the other woman's wrist, used the force to pull the knife out of her own chest, and slashed it across Cui Jiayi's neck under Cui Jiayi's shocked gaze.

After Cui Jiayi collapsed, Su Qing stood in the floodwater for a long time.

In the picture, she was covered in blood, her hair was soaked and stuck to her face, and her lips were pale and bloodless.

She looked down at the wound on her chest that was still bleeding profusely, then at Cui Jiayi lying on the ground not far away, then turned around and walked step by step to the deformed car, slowly squatting down outside the car door.

She reached out her left hand and gently stroked Jiang Ran's cheek, a very faint smile curving her lips.

Then the rain intensified, blurring the image slightly, but the sound remained clear.

She spoke to Jiang Ran, and said a lot of things.

She talked about the cake, the recipe, and how much she wanted to see her eyes light up when she took the first bite.

She said that her sister seemed to be breaking her promise this time. She held Jiang Ran in her arms and gently patted her back until the sound grew softer and softer until it disappeared into the sound of rain.

It also records the girl waking up from her coma, pressing her skirt against her sister's chest wound, frantically searching for her phone, staggering to her feet and looking around for help, only to see an empty road and increasingly heavy rain.

The document records her kneeling beside her sister, pressing her sister's cold hand to her face, calling "sister" repeatedly in a broken voice, and finally curling up in the downpour, holding her hand up to shield her sister, who had already closed her eyes, from the rain.

Captain Zhang watched this footage many times.

Each time, he would remain silent for a long time, then take off his reading glasses and slowly wipe away the non-existent fog on the lenses with his cuff.

He has seen many cases, many victims, and many people who have shown amazing courage in dire circumstances.

But this girl named Su Qing, he thought about it over and over: a penetrating knife wound in the fourth intercostal space on the left side, a ruptured pericardium, a knife tip piercing the anterior wall of the left ventricle, multiple fractures of the left ribs, a fracture of the distal radius of the left arm, multiple soft tissue contusions all over the body, plus the fatal knife wound in the chest and the penetrating wound in the palm of the right hand.

Any one of these injuries would be enough to render an adult incapacitated instantly.

But not only did she stand up and snatch the knife from Cui Jiayi's hand, completing her counterattack, she also managed to walk back to her sister's side, make sure she was safe, and say her last words...

"Doesn't she feel pain?" the young police officer next to her couldn't help but ask.

Captain Zhang put his glasses back on, his gaze fixed on Su Qing's pale yet smiling face in the frozen image. He remained silent for a long time before finally speaking: "Pain...she must be in so much pain...but she can't care about the pain, she has someone to protect..."

Sun Yaqin watched the video in the police station's conference room.

She didn't cry out, but just gripped Cheng Yi's hand tightly. The nails on her other hand dug into her own flesh because of the tight grip, and her whole body was trembling violently.

When Su Qing reached out to touch Jiang Ran's cheek for the last time and said, "You must live well," Jiang Ran abruptly turned her face away, resting her forehead on Cheng Yi's shoulder, her shoulders heaving silently.

Yan Ning didn't come to the police station with anyone. He just stood in the back corner of the conference room, his hands in his suit trouser pockets, without moving an inch from beginning to end. But when the image froze on Su Qing's last smile, his fingers, gripping the lining of his pockets, turned white.

Jiang Mingyuan sat in the front row and didn't say a word from beginning to end.

Every time Su Qing stood up, every time he reached out, every time he blocked the blade aimed at Jiang Ran, his back hunched over a little more.

Cui Ying didn't come... She's still at the hospital watching over Jiang Ran.

But Jiang Ren watched it for her; he sat next to his father, his eyes red the entire time.

Jiang Yi was already crying and squatting on the ground.

She hugged her knees, buried her face in her arms, her shoulders trembling violently, curling up into a tiny ball, as if this would wake her from the nightmare.

The final frame of the scene shows Jiang Ran's heart-wrenching cries being swallowed by the torrential rain.

The conference room remained silent for a very long time. No one spoke, no one got up, and only the cooling fans of the imaging equipment continued to hum softly.

Captain Zhang slowly closed the case file, placed it neatly on the table, then stood up and bowed gently and solemnly to the still photograph.
