Sheriff Uncle, open the door quickly! I've come to solve a case!

"The boy's name is Xu Chengxuan. We found out that the villa he came from belongs to his parents. We have already contacted his parents, and they should be arriving soon."

Zhao Tai stood in front of his desk, having already sent all the information he had gathered to Qin Qingzhou.

Qin Qingzhou carefully looked at the information on the computer while listening to him speak.

"However, there is one thing: Xu Chengxuan is not the biological son of the Xu family. The Xu family has another son named Xu Wang, and Xu Chengxuan has a history of treating heart disease."

Qin Qingzhou paused, her fingertips pausing. "Which hospital did you get treated at?"

Just as Qin Qingzhou had expected, the answer was: "The one we went to today."

Given this, the nurses in the hospital might not remember Xu Chengxuan, but the doctors certainly wouldn't forget him.

Why did Dr. He pretend not to know Xu Chengxuan?

They even concealed the fact that he had a heart condition.

"Why did you call us over in such a hurry?" A commotion came from outside the office. Qin Qingzhou frowned slightly and got up to go out.

It was Xu Chengxuan's parents who arrived. Qin Qingzhou walked up to them and nodded slightly to them politely: "I'm sorry to contact you at this time. We have found your son, so we thought we would contact your relatives as soon as possible."

"Son!" Xu's mother suddenly cried out excitedly, "Where is my son? Let me see him!"

"Please calm down, you may not see your son for the time being."

"What do you mean? What have you done to my son?" Xu's mother walked excitedly toward Qin Qingzhou, her tone aggressive.

Qin Qingzhou remained unmoved, standing straight and staring at Xu's mother without any emotion.

Seeing that he didn't move, Xu's mother cursed him a couple of times and then retreated in a huff.

Mr. Xu hurriedly stepped forward and pulled his wife away, saying, "Honey, it's alright, don't worry. We're already at the police station, let's hear what the police officers have to say."

"Officer, I'm so sorry, my wife was just too worried about our son. As parents, please understand."

"It's nothing." Qin Qingzhou led them to his office, and after closing the door, he asked directly, "Since you've been looking for the child for so many days, why didn't you call the police?"

Xu's mother stiffened, and soon began to cry again, wiping away her tears.

While patting her back, Xu's father replied to Qin Qingzhou, "These days, kids are all rebellious. We thought he was throwing a tantrum and wanted to run away from home, so we didn't pay any attention to him. Besides, he has money on him, so he shouldn't starve. He'll come back when he runs out of money."

"Officer, what happened to my Xu Chengxuan?"

Qin Qingzhou carefully examined them before returning to his desk, taking his laptop, and placing it in front of the two of them.

There were several videos on the computer, and Qin Qingzhou played them one by one.

Mr. Xu frowned as he stared intently at the video.

The video shows the surveillance footage that the police found earlier. In almost every video, Xu Chengxuan walks unsteadily, just like a zombie in a movie.

Mr. Xu was terrified and immediately sat up straight: "My Xu Chengxuan! What's wrong with him? Why is he like this?"

Qin Qingzhou didn't answer him, but instead asked, "Are you sure it's Xu Chengxuan?"

"Absolutely! Of course we're sure! How could we, as parents, possibly mistake our child?"

"Okay." Qin Qingzhou straightened up and stood up. "Our police are already looking for them, so don't worry, we'll find them soon."

"But before that, I have a question I'd like to confirm with you both."

"Please ask." Mr. Xu nervously rubbed his hands together.

"During our investigation, we discovered that Xu Chengxuan had undergone heart surgery, is that correct?"

Xu's mother suddenly covered her face and cried, "Yes, Xu Chengxuan has congenital heart disease..."

"That bad auntie is lying!"

Before Xu's mother could even speak, she was interrupted by the baby's soft voice.

Xu's mother was taken aback and turned her head to look. She saw the office door open and a tiny little baby standing in the doorway with a grain of rice on its face, looking very angry.

Her uncle had previously told her not to disturb adults while they were working, so she had actually returned long ago and had been eavesdropping at the door without disturbing them.

It turned out that the uncle and aunt were lying all along, and the uncle seemed to know nothing about it.

Bai Zhizhi couldn't stand it any longer, so he pushed the door open and went in.

Mr. Xu's expression changed instantly, becoming evasive for a moment before quickly regaining its smile: "Little friend, this is a police station, not a place for you to play around. Go play outside first. You're so cute, how about Uncle goes out and buys you some candy later?"

"Zhi Zhi is just as talented as Tang Tang!" Bai Zhi stubbornly shook her head, still pointing at them, "You've been lying all along!"

"My brother doesn't have heart disease at all. The one who does is..."

"Whose child is this? Officer, is this your child?" Xu's father suddenly interrupted her, loudly questioning, "You police officers can bring your kids to work? Is this how police officers do their job? Forget it! Honey, let's go! I don't think these police officers are genuinely trying to find our son!"

"Let's go! We'll find it ourselves!"

The two men shoved Qin Qingzhou aside and left angrily.

After the two left the police station and got into the car, Xu's mother wiped away her tears, but instead showed worry: "How did that child know we were lying?"

"Nonsense, what could a child possibly know?" Mr. Xu's expression was gloomy. "Forget it, let's hurry up and find someone. It would be bad if the police found us."

The Xu family had been searching for Xu Chengxuan, sending out so many people, but they hadn't heard anything from him. Instead, news came from the police first.

If the police find it first... No, they absolutely cannot let that happen!

Inside the police station, Bai Zhizhi was startled by Xu's father's loud voice. She pouted pitifully and went to Qin Qingzhou for a hug.

Qin Qingzhou picked her up, and Bai Zhizhi hugged his neck, saying, "Uncle, they're all lying."

Qin Qingzhou patted her back expressionlessly: "Yeah, I know."

"My uncle will always believe in Zhizhi."

"Zhizhi, what can you sense?" Qin Qingzhou placed the little guy on the sofa.

Tell me everything you sense, and I'll arrest them and apologize to you.

Bai Zhizhi was overjoyed and couldn't wait to tell Qin Qingzhou everything about herself.

After Bai Zhizhi finished speaking, Qin Qingzhou couldn't help but gasp.

How could such an inhumane thing happen? Where did they put the law?

To ensure he hadn't misunderstood Bai Zhizhi's meaning, Qin Qingzhou specially brought out photos of Xu Chengxuan and Xu Wang and placed them in front of Bai Zhizhi for her to recognize.

"Zhizhi, point to the photo and say it again."

Bai Zhizhi patiently repeated it again.

Bai Zhizhi pointed to Xu Chengxuan's photo, then to Xu Wang's photo, and her sweet voice revealed a terrifying truth.

"This older brother's healthy heart was transplanted into this older brother's body!"
