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

"The mirror is inside the house."

Bai Zhizhi frowned and carefully sensed it.

Just a little bit more, almost there...

As Bai Zhizhi grows up and helps others, she accumulates more and more knowledge and skills.

"The mirror is...underground!"

Bai Zhizhi opened her eyes and looked at Qin Qingzhou with surprise: "Zhizhi saw it, underground!"

underground?

Qin Qingzhou immediately realized: "The basement!"

Bai Zhizhi turned and ran, shouting, "Quick, catch the bad guy!"

Before he could run two steps, Qin Qingzhou picked him up: "You can't go, it's dangerous."

Yu Bei pushed open the door and went out: "Your uncle is right, Bai Zhizhi. You stay here and observe the abnormality of the mirror. I'm going to the basement."

"Okay." Bai Zhizhi stared at Yu Bei and, seeing no signs of impending death, obediently nodded. "Brother, please be careful."

"Yes."

"I'll go with you." Qin Qingzhou followed. "Don't misunderstand, I just don't trust you and I'm afraid you'll let the murderer go."

Yu Bei didn't say anything, but gave Song Qiu a look, telling her to take care of Bai Zhizhi.

The entire villa was plunged into darkness. The owner of the villa usually did not live here; only the butler lived here, and he was already asleep.

The two ran out of the villa. The basement was outside the villa. From the front door, they went around to the back and there was a staircase leading down.

During the day, they had no idea that the basement existed.

The basement door had been modified, and a ring of sealing cotton had been glued around it.

Qin Qingzhou took the lead and tried to open the basement door, but failed several times.

"Get out of my way," Qin Qingzhou said coldly.

Yu Bei took two steps back, and Qin Qingzhou kicked the doorknob, which immediately bent. Then, she quickly removed the lock, but even so, the door was difficult to open.

The sealing cotton was pressed tightly against the ground, and it rubbed against the ground when the door was opened, as if the murderer was not allowing any air to enter.

After struggling to open it, Qin Qingzhou and Yu Bei both smelled a very damp and strong odor.

Yu Bei coughed, clearly disgusted by the smell.

The basement was already poorly ventilated, and after being filled with moisture for two days, it developed a musty smell.

The mirror they had been looking for was inside, right opposite the door.

In addition, what shocked them even more was that the small basement, which was only a dozen square meters, was filled with humidifiers of all sizes.

Qin Qingzhou now knows the cause of death.

This murderer actually used a large number of humidifiers to create air with extremely high moisture content, causing Wang Yichen to drown on the dry land!

Since no specific autopsy has been performed, as long as the police intervene and conduct an autopsy on Wang Yichen, they will definitely find a large amount of blood in his lungs.

"How much hatred must there be?" Yu Bei asked incredulously.

Qin Qingzhou went in first and looked around the room.

"On the day of his death, Wang Yichen's parents were both attending a banquet, Wang Yiwen was playing games, and this can be confirmed by contacting the people he was in a team with. Wang Yichen's brother was at the company."

Qin Qingzhou analyzed seriously, "Then the only person who has the time to commit the crime is the housekeeper who has been living in this villa."

"I'll contact the city police immediately to come and arrest them."

"Wait." Yu Bei pressed down on his hand, which was on the phone. "What did you mean by 'murder method'? Are you suggesting I used a mirror to kill him?"

"You don't need to worry about that." Qin Qingzhou tried to shake off his hand, but found he gripped it even tighter: "What are you doing?"

"Preventing the police from making an arrest is an offense of obstructing official business!"

"No, I just meant... if the butler really is a superhuman, it's best to leave him to me."

Qin Qingzhou thought Yu Bei was completely insane.

Does he know what he's doing? He actually let a policeman release a criminal and hand him over to this private detective who appeared out of nowhere?

"Yu Bei, I think our cooperation can't continue. Once I bring this person back, I'll hold you accountable." Qin Qingzhou forcefully shook off Yu Bei's hand.

Yu Bei sighed, unsure of what to say.

What they didn't notice was that the door was slowly closing at that moment, and the butler was blocking it from the outside with an iron bar.

Countless humidifiers turned on at the same time, spraying out water mist, and within seconds, the air and visibility began to blur.

"What's going on!"

The two immediately went on alert. Yu Bei went to try to turn off the humidifier, while Qin Qingzhou went to open the door.

But all of this was to no avail.

The door was completely blocked, and no matter how hard you tried, you couldn't push it open.

The humidifier was specifically purchased with remote control, so there's no way to turn it off here.

Qin Qingzhou smashed a humidifier, which lingered for a while before becoming unusable.

But it was too late. By the time Qin Qingzhou had managed to smash a humidifier, the entire room was so dark that you couldn't even see a few centimeters away.

"Cough cough!" Yu Bei's nasal cavity was filled with moisture, making it impossible for him to breathe.

He works in an office all year round and is physically weak. He starts to feel dizzy after lacking oxygen.

"Hey!" Qin Qingzhou heard his voice and groped around to find him.

But Yu Bei kept coughing with her mouth covered and didn't answer him.

Gradually, Qin Qingzhou also began to experience some oxygen deprivation.

……

Bai Zhizhi remained nervously in the room. Her uncle and brother had both left, and she was a little afraid of the atmosphere in the room, so she could only secretly lean against Song Qiu.

Song Qiu outwardly looked down on the little brat, but Ye didn't move and let her lean on him.

"Why did it take so long? I'm so sleepy," Song Qiu complained.

Bai Zhizhi was dozing off beside her when a sudden pain in his heart jolted him awake.

Turning around, I saw that a patch of standing water vapor had formed in the area enclosed by the wire in the room!

"Uncle is in danger! Sister! Help Uncle! He's drowning!"

Song Qiu also woke up immediately and saw the shocking scene.

Damn it! Yu Bei and Qin Qingzhou are together! Doesn't that mean Yu Bei is in danger?

Without saying a word, she jumped up and ran, while Bai Zhizhi, with her short legs, scrambled to keep up after a few steps.

"What should we do? Zhizhi needs to save her uncle!" Bai Zhizhi paced anxiously in the corridor.

Water mist... mirror...

Bai Zhizhi immediately ran back to her room, and in her panic, she tore apart several red threads.

"The mirror... my brother said that this mirror is the one that connects to the passage."

"To gain knowledge, one must open the channels..."

Bai Zhizhi hurriedly took out a talisman, drew a talisman, and stuck it on the mirror.

"Yes, you can... Knowing this, you definitely can!"

She gritted her teeth, raised her hand and touched the mirror. In that instant, the mirror melted, and Bai Zhizhi's eyes widened as she slowly stepped into the mirror.

The fog instantly filled her nostrils, and her vision blurred. Bai Zhizhi didn't care about anything else: "Uncle! Brother!"

Bai Zhizhi saw the tall, unsteady figure: "Uncle!"

Bai Zhizhi took out the talisman and ran over, tugging at Qin Qingzhou.

Qin Qingzhou had better lung capacity and was able to persevere; the amulet in her arms was slightly warm.

"What are you doing here?!"
