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

"Knock. Knock."

The knocking was very light and slow; Qin Qingzhou initially thought she had misheard.

But as a seasoned criminal investigator, he had honed his hearing, and he was certain that the knocking was not a mistake.

For safety reasons, it's generally not advisable to look out through the peephole.

But for some inexplicable reason, he didn't think about anything, as if something was pulling him along.

First, I looked out through the peephole. The corridor outside was dark and empty, with no sign of anyone. Even the automatic lights were not on.

Then slowly place your hand on the handle, and with a little pressure on your wrist, the door will open.

The amulet in her pocket suddenly became extremely hot, showing signs of burning, which jolted Qin Qingzhou awake.

He took a deep breath, as if he had been pulled out of a dream, and took several steps back.

"What's wrong?" he murmured.

The amulet almost caught fire; was he nearly killed just now?

What's outside the door?

He didn't go to look again. Instead, he closed all the doors and windows of the house tightly, then sat down at the desk next to Bai Zhizhi and stayed by her side.

After keeping watch all night, Bai Zhizhi woke up early the next morning and wanted to wake Qin Qingzhou, but found him sitting next to her reading a book.

"Uncle~" the little dumpling said softly, rubbing her eyes.

"Are you up?" Qin Qingzhou closed her book and then drew back the curtains. "Why didn't you sleep in a little longer today since you don't have school?"

Bai Zhizhi opened her arms, wanting Qin Qingzhou to hug her: "Yesterday I heard Aunt Hehe say that she was going to see the older brothers and sisters at the orphanage today, and Zhizhi wants to go too."

"You heard all that?" Qin Qingzhou bent down and carried her to wash up. The little one had just woken up, her body was warm and soft, and she smelled of milk, which made Qin Qingzhou feel sleepy.

"Isn't Jiu Jiu asleep yet?"

Bai Zhizhi brushed her teeth while standing on the booster chair, her words muffled and unclear.

"No." Qin Qingzhou didn't hide it.

Then the two of them squeezed together and brushed their teeth in silence.

I didn't hide it, but I was too lazy to say it.

However, not saying anything doesn't mean you can keep it from Bai Zhizhi. After the two finished breakfast and were about to leave, Bai Zhizhi stood at the door for a long time, her small face full of seriousness.

The door was filled with yin energy, clearly indicating that it wasn't just a ghost that had passed by, but that it had lingered there for a long time.

However, Bai Zhizhi had already put up various talismans in the house, and Bai Zhizhi herself was there to protect the family, so the ghost could not enter and could only stay at the door.

She pointed to the door: "Uncle, a spirit came to our house last night."

Qin Qingzhou paused, suddenly remembering what happened last night.

"Someone knocked on the door last night."

Bai Zhizhi immediately nodded to confirm, "That's it, that's it! Uncle, you didn't open the door, did you?"

Qin Qingzhou: "It didn't open, it almost did."

"That's good. If you open it, your uncle will be possessed by a ghost."

"What do you mean?"

The two talked as they got into the car, with Xiao Zhizhi acting like a little teacher, explaining things very attentively.

"The ghosts that wander among humans have no physical form, but they can use yin energy to touch things in the real world, such as ghosts knocking on doors, calling names, etc., all to lure people in the real world. Once a person falls into its trap and opens the door or turns around, they will be possessed by the ghost, and the ghost will use the person's body to fulfill a vow."

Qin Qingzhou then felt a bit scared.

He was almost possessed by a ghost last night.

If a ghost really possesses him, Bai Zhizhi will be the first to get hurt.

Bai Zhizhi gently touched Qin Qingzhou's hand to comfort him, "Uncle, don't be afraid. With Zhizhi here, you're safe."

"Was it the same situation as that case involving someone possessed by a cat spirit?"

Bai Zhizhi shook her finger: "It's different."

"That was just the cat taking their bodies off and putting them back together as a human; it wasn't possession."

Qin Qingzhou hesitated for a moment, thinking to herself, "I should have known better than to say it."

"The ghost failed to possess me last night, but it will come back tonight," Bai Zhizhi said, making a startling statement.

Qin Qingzhou glanced at her sideways: "Isn't it safe?"

"Don't be afraid, Uncle. Zhizhi can protect you. The ghost possessed you because it wanted to fulfill a vow. Today, we'll welcome it in and help it complete its wish."

Helping ghosts fulfill their wishes?

Qin Qingzhou tightened his grip on the steering wheel slightly.

……

When the police arrived at the Little Sun Welfare Home, the children and the director came out to greet them.

The director was a woman who lost her child in an accident, so she later established an orphanage to give other children a home.

It turns out that the children from the Spring Blossoms Welfare Home only arrived yesterday, and the director was so heartbroken when she brought them back that she burst into tears.

The children were initially wary of them, fearing it would be another hell, but when they saw the headmistress in tears, they relaxed their guard.

"Brother and sister!" Bai Zhizhi shouted as she got out of the car and ran towards Yun Qilin and Nian.

The snacks she was carrying fell to the ground with a clatter, and Qin Qingzhou followed behind with a wry smile as she picked them up.

"The director took us to watch TV, and we saw you on TV." Lin Nian, who wasn't very tall herself, struggled to carry Bai Zhizhi into the orphanage.

"Hehe! You know that pretty well, don't you?"

"You're amazing! You even solved a murder case." Lin Nian looked at him with envy. "When can I be like you? I want to be as amazing as you."

"I can have it today!" Bai Zhizhi struggled to get down.

Just then, the dean and the police gathered all the children on the playground. Bai Zhizhi, holding Lin Nian's hand in one hand and Yun Qi's hand in the other, stood at the very front.

"Zhizhi heard from her uncle that he's teaching the kids self-defense techniques today, and they can become really awesome!"

The instructor for the self-defense techniques was Zhao Tai, a field officer from Team One. He stood on a platform set up in front of the playground, holding a microphone, and spoke in a serious tone.

"To improve the physical fitness of citizens and protect their own safety, blah blah blah... The City A Public Security Bureau, in conjunction with the Little Sun Welfare Home, is launching the first round of public self-defense classes. Let's begin!"

This public lecture was a collaboration between the Municipal Public Security Bureau and the media. All the police officers present, including Bai Zhizhi, were in uniform.

A series of cameras were all pointed at the playground, while simultaneously broadcasting news live.

The little ones stood in neat rows, not daring to move in front of the camera.

Bai Zhizhi, dressed in a police uniform, stood at the very front, head held high, looking every bit like a leader.

Actually, she didn't need to stand with the children...

However, the officers thought she was too cute, so they deliberately didn't say anything, thus tricking the child into getting involved among the children.

"Children, look, if a bad guy grabs you from behind, how do you escape? Please pair up, one of you playing the bad guy."

Zhao Tai and another police officer demonstrated.

Lin Nian and Bai Zhizhi formed a group, while Yun Qi and another boy formed a group.

"Does any kid know how? Come up and demonstrate!"

Bai Zhizhi jumped up and raised her hand: "Zhizhi knows!"
