Not long after the car drove out of the city, Gu Song saw a familiar figure on the side of the road. He didn't expect to see that child again so soon, and his mood suddenly became nervous and excited.

"Stop!" He shouted at Fan Cong. The latter was startled by this sudden order, thinking that he had accidentally scraped something, quickly pulled over and stopped the car, and asked anxiously: "What's the matter?" Did I hit someone? ”

Gu Song didn't answer him, quickly unbuckled his seat belt, pushed the car door and walked down. Fan Cong felt inexplicable, he didn't dare to delay for a second, pulled out the car key and got out of the car with Gu Song to check the situation, but saw Gu Song walking hurriedly towards a little boy on the side of the road.

The boy was wearing shorts and a T-shirt, and he was carrying a bulging school bag behind him, and his back looked thin and thin. Judging from the direction he walked, his destination was the R City Public Security Bureau, which was not far away.

"He Weiqi!" Gu Song called the boy. The boy stopped, turned around, and looked at Gu Song in surprise. After a few seconds, there was an imperceptible smile on his face.

Since last night, Gu Song has been very worried about the boy's psychological condition, but when he thinks of the boy's indifferent attitude, he doesn't know what to say for a while. After holding it for a long time, he just asked lukewarmly, "Didn't you go to school today?" ”

"Nope." He Weiqi replied lightly, "My mother helped me ask for leave from the teacher." After a pause, he continued, "My mom went to work, and I sneaked out of the house. ”

"You ......" Gu Song pointed to the gate of the Public Security Bureau and asked, "Where are you going?" ”

"Hmm." He Weiqi nodded slightly, "I'm here to find you, I want to talk to you." ”

Gu Song looked at the 10-year-old boy in front of him who was less than 1.4 meters tall in surprise, and he didn't feel that he was talking to a child at all. Gu Song had no way of knowing what he was like before the crime, but at this moment, the maturity and calmness shown by the boy, and even a little bit of domineering, made people feel a little uneasy.

"Let's go, I'll take you to the city bureau. It just so happens that our captain wants to meet you, too. Gu Song said that he was about to step forward to get He Weiqi's little hand. Unexpectedly, the latter suddenly became vigilant, dodged a few steps back, and said resolutely: "I don't see anyone, I just want to talk to you." ”

"This ......" Gu Song smiled bitterly, a little embarrassed and a little embarrassed. You see, your identity is quite special, and you ran out of the house secretly. If I take you away quietly, I can't afford to be responsible if something happens. So......" Gu Song took out his mobile phone from his pocket, "at least let your mother know your whereabouts, right?" ”

"Officer Gu......" He Weiqi said with a cold look at him, "You know that my mother doesn't want me to have contact with the police. If you let her know that I'm coming to you, what do you think the outcome would be? ”

Thinking of Ms. Du's character and her protection and doting on her son, Gu Song reluctantly made a gesture of surrender and put the phone back stupidly. He looked at He Weiqi's indifferent face again, as well as those unpredictable eyes, and said in his heart that this child is too willful, he is only 10 years old and is so rebellious, and he may not know what he will become when he grows up.

It is conceivable that Fan Cong's request to go together was also rejected by He Weiqi. He emphasized again that he just wanted to "talk" with Gu Song alone, which made the two adults confused, and he felt even more crying and laughing in his heart.

In retrospect, Gu Song always felt that this incident was very incredible. Sometimes, people really have to believe in fate and the so-called fate. It seems that he and He Weiqi are destined to meet and meet in this way, and then to the later love-hate. It's like a hidden quest in the game, and only when it is triggered can you advance a certain story. He felt sorry for him, understood him, and protected him, but he couldn't help but hate him and hate him from the bottom of his heart. But in the end, he still couldn't blame a child for the fault of an adult.

Twenty minutes later, Gu Song took He Weiqi to the Pizza Hut restaurant on the first floor of a department store and picked a hidden position to sit down. Gu Song didn't have much appetite, so he only ordered a drink to relieve the heat, but he didn't expect He Weiqi to show a food amount that was extremely inconsistent with his figure, and ordered 9-inch pizza, chicken wings, salad, cake and ice cream by himself.

Seeing this scene, Gu Song was a little surprised, but his strange mood was also slightly relieved: this guy finally began to look like a child.

"Thank you for your treat." While waiting for the meal, He Weiqi said to Gu Song embarrassedly, "My mother usually doesn't let me eat these things, saying it's unhealthy." ”

Gu Song smiled and waved his hand, and teased: "You look down on me so much, give me face like this, I already feel very honored." ”

"You must think I'm annoying, don't you?"

"No, I like you." Gu Song looked at He Weiqi's eyes with interest, and for some reason, those eyes that hid his heart gave him a sense of déjà vu. "How to put it, I think you are different from other children, you have a temper and a personality, I can't help but want to get to know you, and I also want to help you get out of the shadow brought by the case from the bottom of my heart. I just don't understand why you don't want to meet other people, but instead call me out to talk? ”

"Maybe it's because my first impression of you was better. It seems to me that you are the one who can try to understand me. ”

Hearing this, Gu Song was stunned for a moment, not quite understanding what He Weiqi meant. "We're all going to understand you, whether it's your family and friends, or those of my colleagues, and everybody knows that last night was a very difficult one for you. Don't say it's you, even if an adult is allowed to go through the same thing, he will be frightened and even break down. So no matter what strange thoughts you have in your heart, how scared you are, it's inevitable. If you believe me, say what you hold in your heart and let me help you, okay? ”

He Weiqi didn't answer, but his eyes dimmed. He took out his mobile phone, turned on the notepad function, handed the phone to Gu Song and said, "Don't you want to know me?" I'll meet your request right now. ”

"What do you mean?" Gu Song took the phone and asked uncertainly, "Do you want me to do some kind of test on you?" ”

"Hmm." He Weiqi nodded seriously, "You can write a random set of numbers on your mobile phone, the more chaotic the better." ”

"How many?"

"The longer, the better."

"Is 30 enough?"

"Well...... He Weiqi thought for a moment and said, "50." ”

Gu Song was taken aback, and he probably knew what He Weiqi wanted to explain, so he wrote a set of 50-digit numbers according to his request.

"Do I need to count your time?" Gu Song asked.

"No, I'll just read it in its entirety." He Weiqi took the phone, stared at the long string of numbers on the screen and scanned it from beginning to end, then raised his head and said, "Okay." ”

Gu Song took back his mobile phone, and just wanted to say, "You carry it, I'll watch it for you." He Weiqi digressed the topic, "Wait, human memory can be divided into instantaneous memory, short-term memory and long-term memory according to the preservation time. Instantaneous memory is generally between 0.25 seconds and 2 seconds. Short-term memory is retained for only 5 to 20 seconds without repetition, and the longest is no more than 1 minute. ”

"So you want to prove that you can not only remember those numbers quickly, but also remember them for a long time?"

"Yes, I don't need to repeat my memory, and I'm not afraid of being distracted by other things in the middle. So when I'm done with this meal, I'll recite the numbers to you as they are. ”

Gu Song opened his mouth in surprise, and suddenly understood what was different about the boy in front of him. From childhood to adulthood, among all the people he has been in contact with, the person with the best memory is his good friend Qin Yu, but Qin Yu does not have the ability to forget.

After a few seconds of silence, He continued: "Not just numbers or words, I can clearly remember almost everything that happened around me every second of every day. Advertisements on the streets, license plates speeding by, I unconsciously remember them whenever I see them. Even those who glanced at it in a hurry, I can remember their faces, what kind of clothes they were wearing, what kind of movements they made......" He Weiqi's voice gradually deepened, and his two thick and slender eyebrows were tightly locked together.

Pain, this is the only information that Gu Song can retrieve from He Weiqi's face at this time.

He realized a very terrible problem, and as he thought about it, he couldn't help but feel cold all over his body, and fear gradually seeped out of every pore of his body.

It turned out that the child in front of him was a "hyperamnesia". Maybe He Weiqi didn't know it, but Gu Song could see that the boy had been troubled by this special ability for a long time.

"Hyperamnesia" is an extremely rare medical anomaly, belonging to the branch of non-selective memory, and the clinical manifestation is that the brain has an automatic memory system. People with hyperamnesia use the left frontal lobe, which is usually used to process language, and the posterior cephalic area at the back of the brain, which is usually used to store picture memories, for long-term memory. All of this happens subconsciously. People with hyperamnesia do not have the ability to forget, and are able to remember what they have experienced clearly, down to any detail.

You are not born with this disease. Some people gain this "ability" because they have experienced an unexpected event, and some people have inadvertently happened. No matter what kind of situation He Weiqi belongs to, if he does not have the ability to forget, then what it means to him and how much impact it has on his life by experiencing a brutal and bloody shooting case is really not understandable to ordinary people.
