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

The female ghost always spoke in a swaying manner and kept stealing glances at Qin Qingzhou.

Bai Zhizhi stood in front of Qin Qingzhou, her small frame barely reaching her leg.

But in the female ghost's eyes, it was just a huge golden light blocking her way.

"If you're going to help, then help. Why knock on the door and scare your uncle?"

Bai Zhizhi didn't care about anything else and almost took out the immortal duster to slap the target.

Qin Qingzhou stopped her in time: "Listen to what kind of help she wants to offer."

Bai Zhizhi then snorted and said, "Fine."

The female ghost then said seriously, "It's like this, I had a boyfriend in my previous life. I loved him very much and he loved me very much too, but I drowned in an accident. I didn't even get to say goodbye to my boyfriend one last time. I remembered that you led me to him."

"I'll just go see him, and if I see he's doing well now, then I'll have fulfilled my vow."

Bai Zhizhi pointed at Qin Qingzhou smugly: "Too easy, your uncle is a policeman."

But then she thought, "Why doesn't my sister appear in my dreams? She can appear in my brother's dreams, can't she?"

The female ghost gave a dry laugh, her lips almost splitting open: "I've forgotten what happened before... I can't find her in my dreams."

Qin Qingzhou had been listening in silence, then asked, "You've forgotten everything?"

"Uh-huh!"

Qin Qingzhou: "Your name?"

Female ghost: "I don't remember."

Qin Qingzhou: "What's your boyfriend's name?"

Female ghost: "I don't remember."

Qin Qingzhou: "Address?"

The female ghost: "I don't remember any of it..."

Qin Qingzhou rubbed his temples: "This is a bit troublesome."

Bai Zhizhi's little head followed their conversation, looking back and forth. Hearing this, she said in a sweet, childish voice, "It's okay~ Zhizhi can sense the general location, and then Uncle can find it, right?"

"Then it's settled. You should go now, sister. You can't come back into the house tonight."

The female ghost drooled as she looked at Qin Qingzhou, slowly reaching out to get closer: "Can't you really let me absorb just a little bit of your yang energy? Just a little bit, you have so much yang energy, you don't need this little bit."

Bai Zhizhi took out the immortal dust and threw it at her hand, instantly causing black mist to swirl around.

The female ghost screamed in agony and ran away, saying, "Fine, don't give it to me then! It hurts so much!"

After the female ghost left, the black mist inside the house slowly dissipated.

Qin Qingzhou asked the information department, who had been working the night shift, to investigate all the cases of female students drowning in recent years.

Bai Zhizhi was worried about Qin Qingzhou, so despite being sleepy, she drew a few more talismans and pasted them all by Qin Qingzhou's bedside before finally going to sleep herself.

The next day, when the two went to the police station, they were startled by a female ghost squatting at their door.

The female ghost didn't leave all night. She could smell Qin Qingzhou's yang energy even through the door. She tried to sneak in several times, but was always knocked away by Bai Zhizhi's golden light.

You can't blame her; a love-struck female ghost would crave yang energy...

Bai Zhizhi and the female ghost bickered all the way, giving Qin Qingzhou no peace and quiet. The noise gave her a headache, so she turned on the car stereo.

As a result, Bai Zhizhi and the female ghost stopped arguing and started singing along again.

Bai Zhizhi: "It's still coming from Six Star Street!"

The female ghost: "The sound of a bayan!"

Qin Qingzhou: "..."

Bai Zhizhi pouted smugly: "Sister can sing this song too?"

The female ghost said smugly, "Of course, I'm a pro at surfing the internet. I can sing all your kids' hit songs."

After arguing all the way, they finally arrived at the police station. Qin Qingzhou quickly got out of the car, and it was rare to see him looking like he was "fleeing in panic."

The female ghost's eyes lit up when she saw the police station.

Yang energy...so much yang energy...hehe!

Li Ku bumped into Qin Qingzhou: "Good morning, Captain Qin... Why are you walking so fast? Did you see a ghost?"

Li Ku stared at it strangely for a while, then turned and saw Bai Zhizhi.

"Good morning, Master Zhizhi..."

Bai Zhizhi said to the air, "You have to stay with Zhizhi today, do you hear me? You're not allowed to steal the yang energy of the police officers, or I'll scatter your soul!"

Li Ku felt a chill run down his spine: "...Who is Master Zhizhi talking to?"

Bai Zhizhi then noticed Li Ku: "Good morning, Brother Ku. Brother, hurry up and go away. There's a naughty sister who wants to suck your yang energy."

"A ghost!" Li Kuzi screamed and ran away.

Last night, the IT department packaged all the drowning cases from the past few years and sent them to Qin Qingzhou's intranet.

It's currently summer, and there have been nearly a hundred drowning cases in several nearby cities alone this year, including more than a dozen cases involving women of similar age.

Of course, it cannot be ruled out that no police were called.

Bai Zhizhi sat earnestly on the sofa with her eyes closed, sensing the ghost circling around her.

"Found her!" Bai Zhizhi ran to Qin Qingzhou's side: "My sister's approximate location is in the Huacheng District; her presence was felt there."

Qin Qingzhou immediately filtered the cases, focusing on drowning cases in Huacheng District. In the end, there were five cases that met the criteria in recent years.

But upon comparison, none of the deceased looked like the female ghost.

Seeing Qin Qingzhou at a loss, Bai Zhizhi also felt sad.

"Uncle, don't be sad." The little guy lay on Qin Qingzhou's lap.

"I'm not sad, I'm just thinking." Qin Qingzhou patted her head.

If we target missing persons or registered dead persons, the population base is simply too large.

Now, thanks to Bai Zhizhi providing specific regions, the scope can be narrowed down considerably.

However, there were still many people, and it was unknown when the female ghost had died.

Is there any way to find out which year she died?

As long as it's accurate to the year...

correct.

Qin Qingzhou suddenly glanced at Bai Zhizhi.

"Zhizhi, what was the name of that song you were singing on your way here?"

Bai Zhizhi said, bewildered, "It smells like apples."

"Besides 'Apple Fragrance,' what other internet songs can you kids sing?"

Bai Zhizhi got excited when this was mentioned, immediately jumping to the middle of the office, crossing his arms and waving them up and down in a very comical way: "Big banana, big banana~"

The female ghost seemed to be hearing this song for the first time: "What big banana?"

Time has come.

Qin Qingzhou is an old-fashioned guy; he doesn't understand trendy memes, but he's good at using smartphones.

Those who know how to use smartphones have a promising future.

He immediately found the time point.

"Apple Fragrance" became a hit among children around September two years ago, and "Big Banana" also became popular that year.

We know that the female ghost died in 2024.

Without hesitation, he immediately began screening missing persons and death registration information in the Huacheng District for 2024 that matched the age and gender.

Finally, among a huge pile of documents, they found the deceased whose registered photo looked almost exactly like the female ghost.

"Zhao Qingxue," Qin Qingzhou murmured her name.

Zhao Qingxue trembled, as if something had suddenly been illuminated, her dark pupils filled with shock.

"Hmm!"

She suddenly grabbed her own neck, as if trying to gasp for air. Her pale face slowly turned purple, and she struggled involuntarily with her hands and feet as if drowning.

"Help...help me..."
