On an autumn night after the rain, the temperature plummets, and layers of mist are scattered on the windows of the street.

Qin Rao looked out of the car window, as if counting the lights that were lit up one after another.

Behind every bright window, there may be an ordinary family, but no one will know how many different stories are hidden behind such similarities.

Lin Fan is still telling about the sudden loss of life from the beginning of the 613 case to Zheng Bin and Wu Xing.

Like a heavy burden, such a narrative is destined to be difficult, intermittent, and with various choices that Lin Fan himself can't explain. Perhaps, in human nature and desire, what everyone wants is not the truth, but an excuse to convince themselves to move forward.

Getting off the swaying bus, the streets were much cleaner than the hustle and bustle just now, except for the occasional passenger jumping off the sporadic taxi that passed by, either tight or slow.

The wide road slowly turned into a narrow road, and the street lamps on both sides also fell into disrepair due to disrepair, and only a few still emitted a dim light.

The sound of fragmented footsteps that kept coming from behind him made Lin Fan have a bad premonition.

In the cold wind, he could see the man's long, thin shadow stretched by the streetlamp.

The community where Wu Xing fell was just a few streets away, but there were several dark and narrow lanes ahead, Lin Fan frowned, suddenly stopped, hugged Qin Rao beside him tightly into his arms, and then clinged to her earlobe.

There was a bright taxi light coming, Qin Rao was obviously overwhelmed by the sudden hug, her neck was instantly red, and her breathing became short, but before she could taste the close temperature, she was pulled down by Lin Fan in the taxi parked on the side of the road in the next second. "Youth is really good, look at your strength in love, I won't have it anymore." 's brother is obviously a chatter, and the scene of the two hugging affectionately happens to be watched by him. "The Lukang Homestead Community in front." Lin Fan was obviously not paying attention to his brother, he turned his head and could see the man's suddenly paused figure from the car window. "Laugh at me, don't you? If you can walk these few steps, you have to take a taxi to go far. Brother glanced at Lin Fan in the rearview mirror. Well, let's go around, I'm afraid of the dark, and I don't dare to go through those lanes. The atmosphere was a little solemn, wanting Qin Rao to relax, so Lin Fan made a joke.

"How can you chase such a beautiful girl with such a small guts." The brother laughed and shook his head.

Five minutes later, the west gate of Lukang Community.

"What just happened?" Qin Rao, who got out of the taxi, asked. "It's fine." Lin Fan pulled her into the community, and the gradually brighter light gave people a warm sense of security, "Someone followed us just now." ”

"Oh, no." Qin Rao was a little surprised, but immediately reacted, "No wonder you pulled me to change the road twice just now, and finally hugged him there, it turned out that you were testing him." ”

"Well," Lin Fan nodded, paused for a moment before saying, "Maybe that man saw you holding the camera at that time." ”

"Ah, what should I do then," Qin Rao was a little worried.

"It's okay, don't worry." Lin Fan squeezed Qin Rao's hand, "This kind of photo can't be used as direct evidence, he won't pay too much attention, I guess he may be following us to further explore whether we have other key evidence, after all, the closer we get to the final ending, the more afraid some people will be of what mistakes will occur." ”

"Yes." Qin Rao nodded, looking at the brightly lit community in front of her, but thinking of the story that had happened here, she was still a little scared and hesitant to really step into this world that did not belong to her.

But for the sake of the boy next to her, she is willing to gather some more courage.

=============================================

The moment he stepped onto the rooftop, Lin Fan began to substitute himself into the role of a real murderer, an excellent detective and an excellent criminal will have many of the same qualities, just like the front and back of a coin, and spying on the opposite side of the state is always the most wanted but most difficult thing for them to do.

On the same rainy night, it obviously rained more and longer than today.

Lin Fan stood on the rooftop for a long time, while Qin Rao had been watching him quietly beside him, showing as much composure as possible that should not have belonged to her.

In fact, she was a little scared, after all, this was the scene of a crime in the past, and a life disappeared from here.

The darkness and fear were now gathering up in her throat, like rhizomes that swelled in water, sprouting strings of round fruits, firmly choking her and making her unable to make a sound.

She carefully concealed her fear, not wanting Lin Fan, who was thinking at the moment, to be distracted to take care of herself.

Entering a state of selfless thinking, Lin Fan has been sorting out his thoughts, but he suddenly noticed the slight tremor of Qin Rao beside him, and then he remembered that she was only a sixteen-year-old girl, she put down her flowery world and ran into her own darkness, at least he should give her the greatest warmth and encouragement.

He doesn't think alone, but passes on what he thinks to Qin Rao, "Wu Xing obviously rushed out of the house because of something urgent, he ran to the rooftop, stood in the position where I am standing now, and then fell directly below here.

The parapet wall here is about half a meter high, plus the guardrail above, it is almost a meter high, it should be impossible for an adult to accidentally stumble, even if he is lying on the railing, the center of gravity is particularly offset, it is impossible to fall by himself. ”

Qin Rao listened to Lin Fan's chaotic analysis, and slowly felt that the night was not so terrifying.

"On what basis did the police judge that Wu Xing fell by himself instead of being pushed down?" Qin Rao gradually adapted to this darkness in Lin Fan's slow warmth, and also raised her own questions in a timely manner, "You also said that it was raining heavily that day, and all the relevant evidence such as footprints was washed away, so it shouldn't be possible to just rely on the suicide note and not infer it from the scene, right?" ”

"It's based on the displacement distance of the fall." Lin Fan explained softly, "If someone pushes him from behind, a force will be generated in the X direction, plus gravity in the Y direction, his fall trajectory should be a parabola, not a straight line in free fall, and now Wu Xing's body was found directly below this position, and there is no displacement on the X axis, so the police judge that it is a fall." ”

"That's right," Qin Rao regained some of her vitality, "It feels like a physics practice class." ”

"You can use the crime scene as a practical lesson."

Lin Fan laughed, and the atmosphere was finally not too dull.
