crime profiler in the dark

In a fast-moving express train, there are more than 200 passengers traveling from city A to TMX. At this time, it is not the peak period around the Spring Festival. The original train with more than 800 seats seems a bit empty, and each car has only about ten or so passengers. People, everyone is either reading a book quietly or chatting with their companions in a low voice, only the No.17 car is a little lively.

Car No.17 actually only has about a dozen people sitting in it, but one of them is a little boy about four years old who is very active. For a while, he is excitedly lying on the car window counting the fast reverse electric piles, and for a while singing nursery rhymes taught by his mother , for a while holding the hand of the mother sitting across from him and asking questions, the childish voice echoed in the carriage from time to time, making the deserted carriage a little angry, and many passengers couldn't help but look at him and him with kind eyes. The mother looked at her and smiled knowingly, and praised the boy's cuteness with her eyes.

Suddenly, the train, which was originally at a steady speed, began to brake suddenly, and everyone's bodies could not restrain themselves from leaning forward. When everyone felt strange, the little boy saw through the window that the train was driving to a corner at this time. There was another train in front of the train, and the boy didn't know the danger, so he muttered an impromptu jingle in his mouth:

"Xiao Che, run fast, run home to meet Dad; Xiao Che, chase after him, and if you catch up with Xiao Che, he will become a ghost." He chanted, shaking his little feet off the ground, while looking out the window.

"Really, it doesn't rhyme at all." Mom didn't realize that the train was about to have an accident, and smiled.

As soon as the mother finished speaking, the train they were on had no time to brake, and the front of the train collided violently with another train. Glass, metal carriages, bloody human bodies, and broken luggage flew all over the sky. Because of the huge impact force, the five people in front The sixteen carriages were torn to shreds, and the sixteen carriages behind twisted their bodies like beheaded pythons, rolling and rushing down the green hillside.

The little boy felt the sky was spinning, the screams, the sound of metal cracking, and the sound of luggage beating were heard endlessly. He didn't have time to think about what happened. Sensing the danger for a moment, she instinctively protected him with her body, resisted all external aggression with her slender but strong arms, and supported him with a safe harbor with her soft but firm body.

I don't know how long it took, the little boy woke up, and the surroundings were dead silent. The moment he opened his eyes, his mother's smile came into view. She was looking at him lovingly with her eyes downcast, her expression was like It was as gentle as a goodnight kiss on his forehead every night, but at this time her pupils were lifeless, the color of her slightly raised lips had turned gray, her rosy cheeks had lost their luster, and on her neck, A broken steel rod passed across, cutting her arteries, and the blood had already splashed on the face and clothes of the little boy she was protecting, leaving only a little blood dripping on his face .
