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

Entering Wang Yao's room, it was small, but it was neatly filled with books, and there were many cute little things that belonged to girls on the table. There were also posters of her favorite celebrities on the bedside.

There was also a schedule on her desk, a list of what she needed to do each day, and she would draw a cute little emoticon after each completed task.

No matter how you look at it, this child doesn't seem to have any signs of sadness.

The Queen Mother didn't want to come in, so she sat on the sofa outside.

It was Wang's father who said to Du Hong, "Before the accident, our child made a promise to us that if she got into a good university, she would go to Disneyland. It's just a pity..."

He didn't say anything more.

Du Hong checked the room and found nothing unusual.

Where is Wang Yao's body now?

"He has already been buried."

After thinking for a moment, Du Hong decided to ask, "You don't think Wang Yao committed suicide, right?"

"yes."

"Would you be willing to cooperate with the police investigation into Wang Yao's body? We need to dig her up."

"Huh?" Upon hearing this, Mr. Wang immediately refused: "No, no, the child has already been buried. There's no reason to dig her up. She won't be at peace in heaven."

"Besides, our Yaoyao and Zhou Tianyu died in the same way. If you investigate him, you'll find out how Yaoyao died, right?"

"But if someone imitates your daughter's death and kills Zhou Tianyu, then to find the murderer, we must look at the differences between the two bodies."

The father was so conflicted that he kept pacing back and forth, but in the end he went to ask his wife for her opinion.

The two of them whispered to each other for a long time outside, both very conflicted.

But... if we could find the real killer of my daughter, wouldn't her spirit be even happier?

"Okay, officer, we agree."

After leaving the Wang family's house, Du Hong stood in the corridor and contacted the children's teachers.

The teachers all said that it was impossible for the children to commit suicide. Yao Yao had good grades and was cheerful, and her classmates all liked her very much.

Zhou Tianyu was a classmate who was quite popular. Although his grades were average before, he performed exceptionally well in the college entrance examination, which made his teachers very proud.

The teachers didn't believe the two children's explanation at all.

But they died.

"Captain Du!"

Suddenly, a police officer ran out of Zhou Tianyu's house: "We've found something strange!"

Du Hong went inside immediately, and the police officers led him to the kitchen. Under the stove where they were cooking, they found a small copper basin with two burnt-out incense sticks stuck in it.

"What is this?"

Du Hong poured out the ashes, and hidden in the ashes was half a burnt yellow talisman.

He took a picture of these things, then went out to find the Zhou family, clutching half of the yellow talisman.

When Zhou's parents saw the yellow talisman, their faces changed instantly, and their lips turned deathly pale.

"What is this?"

"This...this is a talisman? Isn't it obvious? Isn't it normal for kids to ask for talismans for their college entrance exams? I went to someone to get one to bless my son so he can get into a good university. Is there a problem with that?"

"No, what is this thing? It has absolutely nothing to do with my son's murder. Instead of looking for this nonsense, you should find the killer!"

Du Hong noticed that they seemed guilty.

His intuition told him something was wrong.

But he couldn't quite put his finger on what was wrong.

The case had been under investigation for several days without any progress, but the Zhou family was making a bigger fuss every day, insisting that the Wang family had killed their son.

Could it be that the Zhou family killed the Wang family? Is that why they suspect the Wang family came to kill their son?

Soon, the paperwork for opening the cemetery and conducting an autopsy was completed, and Du Hong led a group of people and Wang's parents to the cemetery to open the cemetery.

The moment the coffin was opened, everyone was so frightened that their legs went weak.

The coffin was empty; Wang Yao was gone.

Wang's parents were so frightened that they fainted.

After much deliberation, Du Hong finally sought out Bai Zhizhi to investigate this bizarre situation.

Bai Zhizhi is now a super celebrity; everyone knows her as soon as she arrives at the B City Police Station.

Du Hong quickly led them to the scene of the crime. Bai Zhizhi slowly climbed the tenement building, while Qin Qingzhou followed behind.

As soon as we reached the floor where the incident occurred, we could hear Zhou's parents still cursing and swearing at the Wang family's door. The curses they were using were incredibly offensive.

Bai Zhizhi's expression turned serious when he looked at her.

When Mr. and Mrs. Wang heard someone coming upstairs, they didn't even see who it was before they started yelling, "How can a murderer live so peacefully! This is outrageous! The murderer who killed my son deserves to die a horrible death!"

Turning around and seeing it was Du Hong, she rushed over again: "Officer Du, you're finally here again! Did you find any clues? They're the murderers, aren't they? Arrest them quickly! We can't sleep peacefully until they're gone!"

Bai Zhizhi pouted and pointed at them: "You bastards, you're so noisy! Your son was killed because of you!"

Qin Qingzhou frowned slightly.

Kids aren't as cute as they were when they were little, and now they've even started swearing?

It must have been Li Ku who taught him; I'll have to teach him a lesson when we get back.

"Where did this little brat come from! What nonsense are you spouting!" Zhou's mother scolded, then looked closely and realized the child looked very familiar.

Bai Zhizhi, hands on her hips, angrily shouted, "You killed your own son, and you also killed someone else's daughter!"

The soundproofing in the tenement building wasn't very good, and Bai Zhizhi's voice could be heard in the Wang family's home.

The Queen Mother flung open the door, her eyes filled with tears: "What?"

"These two scoundrels went to a Taoist priest before the exam and asked him for a talisman for studying hard. But they found another way and learned that sacrificing someone who was good at studying could make the talisman work. So they sacrificed their uncle and aunt's daughter."

The Zhou couple stopped breathing, but they still tried to remain calm.

How did the child know that?

"Not only that, they also got your daughter's hair, burned it along with the talisman for studying, and then put the ashes under your daughter's bed."

"If you leave her there for four days, your daughter will be sacrificed and die!"

"What?" Tears welled up in the Queen Mother's eyes. Even though she hadn't dared to enter Yao Yao's room for many days, she ran in with trembling legs and found something wrapped in a thread under the bed.

"Ah!" she screamed, and the yarn package fell to the ground.

Zhou's mother collapsed to the ground, panting heavily, no longer knowing what to say.

"Your son actually knows that he saw you sneaking into your sister's house, and he also overheard you talking about it in private. He's under a lot of pressure, especially seeing that he actually got such a high score on the exam. He can't handle it."

"Your son committed suicide, and you killed him!"
