"So what are you going to do now, if that really half a bottle of water is with you, I want you to give it to me. Someone might have noticed you by now. Officer Zhang smoked a cigarette and looked at Pang Fei.

"Someone, someone noticed Pang Fei, Officer Zhang." Shan Wenchun looked at the two people in front of him.

Time seemed to stand still, and Officer Zhang looked at Pang Fei through the smoke.

"Okay, I'll give it to you." Pang Fei's eyes were still fixed on Officer Zhang.

The two of them did not answer Shan Wenchun's question.

Pang Fei took out the remaining half bottle of water that Mi Lan really drank that day to Officer Zhang. The chemicals in it can be detected through technical means, and this is undoubtedly of great help to Officer Zhang to solve the case.

When Yumo returned, he combed through what had happened today, and then he made a phone call.

"You go and test the contents of that half bottle of water, there's something wrong with it." Yu Mo said as he lay on the couch.

"What half a bottle of water......... what are you talking about...... The ......" voice came from the other side of the phone.

"Yes, try to be as fast as possible, and most importantly be hidden." Yu Mo hung up the phone after speaking.

Today's intention of Officer Zhang is by no means so simple, and the key is that he is in order to bring Shan Wenchun.

After Officer Zhang got something from Pang Fei, he immediately went to a person's home, that is, the forensic doctor Fu Hou's house.

Officer Zhang's teacher and Fu Hou are good friends, and the two can be said to be close friends.

When Officer Zhang came here and rang the doorbell, a little girl opened the door for him.

"Children, where are the adults in your family?" Officer Zhang looked at the girl with the step doll in front of him.

The little girl looked in the direction of one of the doors in the room.

Officer Zhang: I heard no sound from the house.

"Hate,... Yes...... Ahhhhh.........h I can't hold on anymore, you tap, ah............ Master......... Division...... Tutor......... You. "A voice coming from inside the bedroom.

"You drive me, master, I can't hold on." A woman's voice came.

"Baby, you hold on, it's coming, it's coming............ Ahh

Officer Zhang heard a voice coming from the house and looked at Shan Wenchun.

He saw a rope on the leg of the table next to him, and the little girl's hand and neck had obvious traces of being tied, and it was obvious that the little girl had broken free from the rope by herself.

Officer Zhang didn't say a word, and the little girl in front of him walked out of the door.

Several people sat on stone benches in the community.

"Officer Zhang, what should we do next?" Shan Wenchun looked at the little girl in his arms.

Officer Zhang didn't answer his question, and suddenly looked at the little girl in front of him, and he hugged the little girl tighter.

"Son, can you tell Uncle what your name is?" Officer Zhang put his head in front of the girl.

The girl looked at him without responding, but slowly pulled a card out of her pocket.

I saw that the card read: My name is Ruoruo, I am 4 years old this year, and I am an autistic child.

Obviously, this should have been written by her parents, and there is the adult's contact information at the end of it, not only Fu Hou's phone but also his wife's phone number.

Officer Zhang suddenly understood why the girl in front of him had autism, maybe it was because she had seen too many things that she shouldn't see, just like the scene in the house just now.

Soon it was noon, and several people were still sitting on the stone bench.

"Ruoruo, Ruoruo, where are you, where are you." In the distance, a call could be heard.

Officer Zhang and Shan Wenchun looked at the two people who walked over. In front is Ruoruo's father, and in the back is his apprentice Zhao Yu.

Fu Hou was a little surprised when he came over and saw Ruoruo in Officer Zhang's arms, and he slowly stepped forward.

"Ruoruo, why are you here, do you know how hard we work to find you?" Fu Hou asked anxiously.

Fu Hou noticed Officer Zhang at this time.

"Zhang Muran, why are you here, you should have graduated now." Fu Hou looked at the man in front of him and said.

"Teacher Fu, after so many years, you still remember me. Today, my friend and I came here to run errands, and I happened to see this kid who seemed to have something. Officer Zhang gestured to Shan Wenchun next to him.

Fu Hou just looked at Shan Wenchun next to him and didn't pay much attention to it.

"Oh, yes, yes, Officer Zhang and I came here to do something, and when we saw this kid wandering around here, as if he was lost, the two of us came forward." Shan Wenchun smiled a little embarrassedly.

"Oh, Ruoruo, why are you here, it's really easy to find my sister and father." Zhao Yu deliberately touched Ruoruo's neck that was tied by the rope just now.

Officer Zhang noticed all this, and it was clear that the woman in front of him knew something.

"It's not too late for me to see the weather, why don't we go out for a drink or two, it's not far ahead." Fu Hou asked with a smile on his face.

Officer Zhang didn't want to go, but then looked at the child in front of him.

"Okay, then it's better to be respectful than to obey your fate, since Teacher Fu is willing to invite me, this opportunity is really rare, how can I thin your face." Officer Zhang turned around and gestured to Wen Chun.

Shan Wenchun held the bag containing the half bottle of water tightly, and then looked at the two people walking in front of him.

Soon he found a place to do it.

At this time, Zhao Yu also sat silently opposite Fu Hou, and opposite her was the girl. Officer Zhang saw the child's somewhat timid expression when he looked at Zhao Yu.

Officer Zhang looked at the child's weak appearance, and took the initiative to sit next to him.

"Teacher Fu, I think I have a relationship with this child, and I want to sit with this child." Officer Zhang said to Fu Hou.

But when Officer Zhang suddenly sat down, the child suddenly turned to Zhao Yu and moved closer to her, obviously this child was also afraid of him.

"I'm sorry, if you may be afraid of people, so ........." Fu Hou didn't finish his words.

"It's okay, it's okay." Officer Zhang looked at Zhao Yu.

"Anyway, Officer Zhang, what have you been busy with lately?" Teacher Fu asked casually.

"Hey, what can I do, it's not blind." Officer Zhang is obviously not on the topic.

The waiter brought the food here.

Zhao Yu's expression was a little trembling at this time.

But so many people didn't notice her expression, but one exception was Officer Zhang.

Officer Zhang turned his head and gestured to Shan Wenchun next to him at this time.

"Teacher Fu, don't hide it, I came to you this time to find you something." After saying that, Officer Zhang took out the half bottle of water from the bag.

Teacher Fu looked at the half bottle of water on the table.

"That's why I'm coming to you this time, I recently came across a tricky case, so I wanted to ask for your help." Officer Zhang looked at the teacher in front of him with a somewhat pleading gesture.

"How can I help you, you say." Fu Hou's expression suddenly became serious.

At this time, the eyes of the two people are facing each other.
