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

Yu Bei was hearing this person's name for the first time: "M country? What's their name?"

"Chen Zhou".

Someone who can make Qin Qingzhou care is probably quite strange.

Yu Bei nodded and did not stop Qin Qingzhou from contacting the Information Department.

"Uncle, what are you saying?" Bai Zhizhi suddenly joined their conversation.

While they were discussing the case, Bai Zhizhi listened from the side, only partially understanding, but she knew not to interrupt if she didn't understand.

As soon as the name "Chen Zhou" was mentioned, she opened her big, round eyes and looked up at them.

"This older brother is already dead~ Why are you talking about him?"

The little guy jumped up: "Are we going to solve this older brother's case? Can we bring Zhizhi along?"

"Dead?" Qin Qingzhou and Yu Bei asked at the same time.

"Yes, this brother drowned."

"Drowning?" They then exchanged a glance and left the room together in perfect unison.

Bai Zhizhi thought she had said something wrong, and scratched her head: "Why didn't you bring Zhizhi along..."

Hearing the knock, the old butler slowly went to open the door and saw Qin Qingzhou and Yu Bei standing there. He bowed politely.

"Is there anything I can help with?"

Qin Qingzhou spoke first: "We want to ask about your son."

"I see. Please come in." The old butler seemed unsurprised and led the two into the room.

The butler's room was not as big as Wang Yichen's room, and apart from the documents piled on the desk, it was completely exposed.

Yu Bei looked around and didn't find the same mirror in his room.

Yu Bei didn't participate in asking about related matters; Qin Qingzhou took the lead.

Qin Qingzhou took out her notebook and asked, "When I asked you before, you said your son was abroad. How is he doing?"

"Hmm, it's alright." The butler's voice remained calm.

Qin Qingzhou looked down, took out her phone, and showed him the information the information department had just collected.

"But I found out that you registered your son's death three days ago. Isn't your son already dead?"

The butler hadn't expected them to find out so quickly, and his lie couldn't continue: "Yes, I lied to you, my son died a week ago."

"What was the cause of death?"

The butler remained silent.

After a long while, he finally exhaled a deep breath: "I don't know what the cause of death was."

Qin Qingzhou showed him no mercy: "Is it that you don't know, or that you're trying to hide it?"

"I don't know," the butler insisted.

Qin Qingzhou didn't expose him because he didn't really have any evidence.

He couldn't just use Bai Zhizhi's words to interrogate the steward.

Why did you lie to us?

The butler's expression didn't even change: "This isn't a lie. It's just that you gentlemen are currently dealing with my young master's affairs. If I were to rashly say that my son has passed away, wouldn't that be disrupting your work?"

"Besides, death is a natural part of life. My son is dead, and there's no need to publicize it everywhere. This is just a family matter for ordinary people like us."

"Okay." Qin Qingzhou slowly stopped the pen tip on the word "mirror" written in the notebook.

"Did you furnish the villa yourself?"

"Yes, I will keep a record of everyone's needs and then we will order custom-made furniture together from the furniture store."

"I find Wang Yichen's room quite strange. There are so many mirrors. Is that something he needs?" Qin Qingzhou asked casually.

"Yes, young master is quite concerned about his image and often needs to look in the mirror," the butler replied fluently.

"Then I'd like to ask about this mirror." Qin Qingzhou took out the photo she had just taken: "Do you still have the purchase invoice for this mirror?"

"Yes, please wait a moment."

The butler returned to his desk and rummaged through a pile of documents. Finally, he took out a folder containing all the purchase orders from that year. After finding the purchase order for the mirrors that were purchased in bulk, he handed it to Qin Qingzhou.

To maintain aesthetic consistency, these mirrors are not sold individually; each mirror comes in five or six sets, and each owner's room will have the same mirror.

Even the strange mirror on the other side had four sets.

After greeting the housekeeper, the two found the remaining mirrors in the rooms of the other owners.

But one mirror was missing, and that was the one that was abnormal.

They searched the entire villa but couldn't find the mirror.

The trail went cold again.

On their way back, Qin Qingzhou fell into deep thought.

The biggest problem now is not where the mirror went. Even if they find the mirror, they have no evidence to prove who used it to kill someone.

If the butler is the murderer, why would he proactively hire a detective to investigate the case?

How exactly did his son die?

The only person who might know the cause of his son's death was Wang Yichen, but Wang Yichen was also dead.

"Perhaps Bai Zhizhi can find out where that mirror is," Yu Bei suddenly said.

Qin Qingzhou paused, looked at him, and gestured for him to continue.

"Doesn't she have the ability to sense things? When the yin energy is at its strongest, let her sense the existence of the two mirrors, and she will naturally know where the other mirror is."

Is it the place with the heaviest yin energy?

Qin Qingzhou, worried that Bai Zhizhi might be in danger, asked, "Why can't you sense anything?"

Yu Bei said helplessly, "Do you think I don't want to? I'm just an ordinary Taoist who learned later in life, unlike a child like her who was born with abilities."

"What needs to be done?"

"Just do as I say."

They stayed in the villa all day without leaving. To prevent others from accidentally entering the room, Song Qiu yawned and sat cross-legged on the floor at the doorway.

It served as a door god.

Inside the room, Qin Qingzhou couldn't hide her expression as she watched Bai Zhizhi and Yu Bei draw talismans.

Each mirror had a broken talisman pasted on it, and the yarn tied to the mirrors hadn't been removed yet. Combined with the talisman, it looked exactly like the scene I saw at Liu Kang's house before—terrifying and eerie.

Wang Yichen's body was still lying on the ground, and the skin discoloration after death was becoming more and more obvious.

Qin Qingzhou found a blanket to cover him up so that Bai Zhizhi wouldn't see him.

While waiting for midnight, Qin Qingzhou didn't rest. He contacted his contacts to thoroughly investigate the cause of death of the housekeeper's son, Chen Zhou.

Because the person died abroad, the investigation is somewhat complicated.

As the clock slowly struck twelve, Song Qiu shook her head vigorously to make sure she didn't believe she was asleep. In the pitch-black corridor, she sat there alone.

Out of the corner of my eye, I saw a dark shadow flash by, disappearing in an instant.

Song Qiu rubbed her eyes, thinking she must have seen wrong.

Bai Zhizhi had already fallen asleep leaning against the table, but Qin Qingzhou woke her up: "I need your help."

"Okay~ Paw Patrol is here to help~" Bai Zhizhi's voice was soft and light as she swayed to the full-length mirror.

Yu Bei crossed his arms and watched her movements intently.

The little guy closed his eyes and slowly sensed the location of the mirror.

"Found it!"
