The two of them drove and tailed those two people all the way. One of them frowned and looked a bit dazed.
After leaving their residence and having a meal, the two went to their workplaces respectively.
It was quite evident that this was how the couple usually behaved. They didn't communicate at all, neither talking nor smiling. They were like two walking dead wandering on the street.
Looking at their appearances, Yi Pin frowned and felt a bit depressed.
However, they still couldn't find any clues.
So the two of them went back and checked the family's medical records thoroughly, but found nothing.
Finally, having no other options, Yi Pin and Shen Yu took the medicine box and the photos of the couple and started searching from one store to another.
Most people said they hadn't seen them or that they had forgotten even if they had.
Until they came to a pharmacy at a turning.
Yi Pin and Shen Yu walked in together and saw the shopkeeper smiling slightly and greeting them warmly.
Then they learned that those two people had really come to this pharmacy and bought Fluoxetine, saying that their depression had flared up and they were in great pain.
Yi Pin stood there stunned. It seemed that there was definitely a connection.
This person's death was closely related to everything they had said.
The truth seemed to be getting closer.
Yi Pin hooked the corner of his mouth and said with a smile, "What should we do now? These two people are so scary!"
Shen Yu shrugged, gently patted Yi Pin on the shoulder and smiled.
Everyone was like this. Even if they were extremely careful, there was no such thing as an airtight wall in the world. Everything seemed to be predestined.
"Call the police!" Shen Yu said coldly.
Since such a big thing had happened, it should be handled by the relevant departments and professional teams.
Moreover, the strength of the two of them was too limited.
Just then, the couple passed by the door.
Yi Pin frowned, feeling an indescribable nervousness. He frowned, not knowing what to do. When seeing the murderers, his heart was pounding.
He felt as if the two people in front of him were staring at him nakedly, wanting to kill him.
Shen Yu reached out and gently grabbed Yi Pin's hand, squeezing it slightly. He hooked the corner of his mouth and smiled.
"Don't worry. I'm here!" Shen Yu's voice rang softly in his ear.
Only then did Yi Pin feel a bit more at ease, and his heart didn't beat so fast anymore.
The pharmacy owner seemed quite calm because she didn't know what had happened and how terrifying the deeds of those two seemingly simple - looking people were.
Shen Yu frowned and said, "Call the police quickly. I saw her carrying a chain. Zi Qi will definitely be abused when she gets back!"
When Yi Pin heard the name "Zi Qi", his eyes went a bit blank. He stared directly at Shen Yu in front of him.
He quickly called the police and then rushed out.
Shen Yu always ran beside Yi Pin.
The two of them followed the road and ran to the slum. They watched as the lights in front of them went on and off, and then came the crying of a child.
The two of them were panicked.
"Hurry up!"
Shen Yu took two big steps forward and frowned.
The two of them knocked on the door, but no one came to open it.
So Yi Pin started kicking the door. The crying of the child inside became more and more miserable and louder, and then suddenly stopped.
Shen Yu frowned and said coldly, "Get out of the way!"
Then he rushed forward and rammed open the door. They saw that the room was empty and pitch - black.
Yi Pin frowned and looked a bit dazed.
"Don't hide. Are you afraid to take responsibility after doing such things?"
Shen Yu was always on high alert, looking around.
"Zi Qi!"
Yi Pin shouted into the dark room.
They only heard a crackling sound inside.
Shen Yu kicked open a door, but there was no one inside.
At this time, something heavy seemed to be thrown at Yi Pin. Shen Yu immediately blocked it. They only heard a dull sound, and then there were scattered glass shards.
"Shen Yu, are you okay?" Yi Pin frowned and looked back to see Shen Yu's pained expression.
Shen Yu snorted and shook his head.
Then the two of them were pushed into a small dark room and locked inside.
Yi Pin supported Shen Yu, who was covering his chest, looking worried.
In the darkness, they saw a small black figure tied to a chair with tape on its mouth. Its face was pale.
"Zi Qi?" Yi Pin frowned, ran over and untied Zi Qi's hands and feet. He looked at the child in front of him with heartache.
"Brother, you're here?"
Zi Qi smiled. There were bruises on his face, blood at the corner of his mouth, and wounds of various sizes on his body.
Shen Yu walked over, ruffled Zi Qi's hair and said gently, "Brother will definitely take you out. From now on, no one will ever treat you like this again. Do you understand?"
Zi Qi instantly burst into tears aggrievedly. He hugged the two of them by the thighs, and his tears kept dropping on the ground.
Just as the three of them were deeply touched, there were sounds coming from outside.
"Humph, you three look like a family. Why do you keep staring at us? Can't you just leave us alone? You little brat, you ruined my life, and now you're causing trouble for us again..."
A shrill woman's voice rang in their ears.
Yi Pin frowned and gently covered Zi Qi's ears.
Then there was the sound of knife - sharpening. Yi Pin instantly felt a chill down his back. Then he felt out of breath, and a sense of depression came with the tense atmosphere.
Yi Pin looked at Shen Yu beside him worriedly. Since they could treat their own child like this, they definitely wouldn't take Shen Yu and Yi Pin seriously. They would only think they were nuisances.
"You two are really asking for trouble. Why do you interfere in other people's business? Why?"
The woman's voice became more and more intense, and the sound of knife - sharpening grew louder.
Yi Pin swallowed hard and kept covering Zi Qi's ears, afraid that he would be scared.
Shen Yu reached out and tightened his grip on Yi Pin's hand, squeezing it. "Don't be afraid. I'm here!"
Such a simple sentence could sometimes comfort people. Yi Pin instantly felt that maybe everything would be okay. At least he wasn't alone in facing these things.
After a while, there was no sound outside. It seemed to be the calm before the storm.
The silent air was filled with a slight chill.
They heard the sound of heavy chains.
Then the door was opened. Yi Pin stared blankly at the scene in front of him, not knowing what to do.
The two of them pulled the shivering Zi Qi behind them.
They stared directly at the scene in front of them. The woman was holding a chain, with a disheveled head. She seemed like a crazy woman who hadn't washed her hair for a long time.
And behind her was a silent man holding a knife.
