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

"I'm sorry, teacher."

Qin Qingzhou, pulling on Bai Zhizhi in his red thermal underwear, obediently bowed and apologized to Teacher Xiaoyang.

"Uncle Zhizhi, you really need to look at who in the family taught Zhizhi these things. Last time it was drawing talismans, and this time it's some kind of cultivation. The other two children have also become strange all the time."

"Okay, sorry." Qin Qingzhou forced a smile.

On the other side, Xingxing's mother and Xie Guan's mother were laughing so hard they couldn't stand up straight, insisting that the two children stand together.

Xingxing was confused, and Xie Guan's face turned bright red.

Xie Guan's mother took many photos of the two little ones together and posted them on her WeChat Moments several times.

"Xiao Guan will be so embarrassed when she sees this photo when she grows up," Xingxing's mother joked.

Xie Guan's mother didn't give him any face: "That's good! He's always so serious, just like his dad. This red long johns moment definitely needs to be recorded so he can show it to his girlfriend later, hahaha!"

After scolding Qin Qingzhou and Bai Zhizhi, Teacher Xiaoyang went to take care of the other children.

With a slight smile, Qin Qingzhou led Bai Zhizhi to the parking lot.

"Uncle, has Zhizhi caused trouble again?"

"No, it's just that you can only cultivate after you go home." Qin Qingzhou lowered her eyes and quickly glanced at Bai Zhizhi.

Red thermal underwear, actually quite cute.

Like the Fuwa mascots in New Year paintings.

Bai Zhizhi had no idea what Qin Qingzhou was thinking. She got into the car happily, still wondering what delicious food her uncle would take her to eat today.

After driving for a while, Bai Zhizhi realized that the surrounding environment was very unfamiliar.

Bai Zhizhi peered out the window: "Uncle, this isn't the way home!"

"Okay." Qin Qingzhou kept his eyes on the car and said, "Let's not go home first, I'll take you somewhere."

"No, no! Is it a fun place? Or a place with good food?"

Qin Qingzhou chuckled: "We'll find out when we get there."

They stopped in front of an office building in the city center, drove to the underground parking lot, and used a QR code sent to them by someone to scan the access control.

The elevator goes directly to the tenth floor, which has been bought by a studio.

"Third Number Agency"

Bai Zhizhi was visiting this kind of place for the first time, and she was full of curiosity. Her nose twitched as she smelled a fragrant aroma.

It smells so good!

"Bai Zhizhi, go knock on the door." Qin Qingzhou released Bai Zhizhi's hand, her meaning unclear.

Bai Zhizhi didn't think too much about it and ran upstairs, banging loudly on the custom-made wooden door.

After a while, the sound of shoes dragging on the ground rang out, followed by a somewhat familiar female voice lazily asking, "Who is it?"

Upon opening the door, the first thing I saw wasn't the little bundle of joy in front of me, but Qin Qingzhou standing a few meters away with her arms crossed.

A sweet, childlike voice came from beneath her: "Sister! It's Zhizhi!"

Looking down, Bai Zhizhi, with her round, bright eyes, gazed at her with delight.

Song Qiu: "...What are you doing here, you little brat?"

"Uncle brought Zhizhi!"

Song Qiu was still wearing her school uniform. It was a bit cold inside with the air conditioning on, so she was wearing her school uniform jacket, had a lollipop in her mouth, and her ponytail was a little loose. She looked very lazy.

Upon seeing an acquaintance, Bai Zhizhi, ever the friendly type, pointed inside and asked, "Sister, may I go in, Zhizhi?"

"Oh..." Song Qiu stepped aside to let them in.

Bai Zhizhi patted the dust off his red thermal underwear before walking in with his head held high.

"?" Song Qiu then noticed her red long underwear and looked at Qin Qingzhou in disbelief.

This guy looks so handsome, what kind of aesthetic sense does he have?

Does anyone have a kind heart and let their child wear long underwear to school?

Qin Qingzhou shrugged, indicating that he hadn't done it.

Bai Zhizhi walked into the house while smelling the fragrance, feeling as if she had entered the world of an anime.

The room was filled with irregularly shaped artworks that looked expensive, paintings that children couldn't understand, a whole row of bookshelves filled with all kinds of books, and a faint fragrance and coffee aroma in the air.

Yu Bei was making coffee at the coffee counter when sunlight streamed in through the side blinds, gilding his body with a golden edge. He wore a pair of gold-rimmed glasses without lenses, giving him a very ascetic look.

The hissing sound of the machine grinding soybeans attracted Bai Zhizhi.

Bai Zhizhi wasn't even as tall as the coffee table, so she stood on tiptoe to see what he was doing.

"Brother Beibei, what are you doing?"

"Make delicious drinks."

"A drink! Even if you know it, you should still drink it!"

The abstinent Yu Bei harbored a wicked scheme: "Okay."

After a series of smooth and fluid movements, a cup of Americano is ready.

He took a small cup and poured some for Bai Zhizhi.

Bai Zhizhi saw that the coffee was black and assumed it was the black sweet drink she had at KFC last time, so she drank it without hesitation.

Then her whole face scrunched up: "It's so bitter!"

"Really? I don't think so." Yu Bei took a sip with a blank expression.

Bai Zhizhi didn't want to talk to Yu Bei anymore, so she ran off to find her uncle.

Brother Beibei is so scary, he actually likes to drink such bitter water.

Qin Qingzhou sat down on the custom-made sofa and began to look around the place.

The whole thing, including Yu Bei, gives people a certain feeling.

Installed.

"After considering it for so long, you've finally decided to cooperate with me?"

Yu Bei slowly sat down on the sofa opposite him and took a sip of coffee.

He scoffed at Qin Qingzhou for using Bai Zhizhi's power, but in the end he still had to cooperate with him.

Song Qiu watched for a while, speechless, as the bored adults inexplicably started their pointless competition. She scoffed and went inside.

Qin Qingzhou sternly corrected his statement: "It's not cooperation. What you're doing is being called a police informant."

"An informant?" Yu Bei laughed angrily. "If I remember correctly, police informants usually have prior criminal records, right?"

"Is there a difference?" Qin Qingzhou sneered.

Private investigators operate on the fringes of the law, and they could easily commit crimes one day.

Yu Bei took a breath and gave a polite but distant smile: "It seems Officer Qin isn't genuinely interested in cooperating."

"Alright then, since we're not going to cooperate, let's settle the fee for the orphanage's case from last time. The person who went last time was our agency's top detective, so it's 100,000."

Qin Qingzhou frowned slightly: "One hundred thousand? Your firm really makes a lot of money."

Yu Bei calmly put down his cup: "We're not hiring for now."

"You don't actually think I don't have the money to pay the service fee, do you?"

Yu Bei looked at him with particularly distressed eyes: "Civil servants who only get a fixed salary really don't have much money."

Qin Qingzhou: "..." She's said a bit too much.

Yu Bei chuckled, finding it quite amusing to tease the steel policeman and the little Taoist priest occasionally.

"Just kidding. An informant is an informant, but since this is our first collaboration, we both need to assess our synergy."

Qin Qingzhou almost pulled Bai Zhizhi away, but upon hearing this, she raised an eyebrow: "How do you assess it?"

Yu Bei took a rough client information sheet from a booklet next to him and placed it on the table in front of them.

"This is a newly received case."

"That should be one of your strengths, want to try and crack it?"
