Two men walked into the low, gray building.

They wore cotton coats, were of medium height, and their caps were so low that their faces could not be seen clearly.

At first glance, they are just two ordinary people, so ordinary that they blend in with the surrounding scenery, as if they are the residents here.

"You say, how will Xiao Wanwan die?" Mu Zening discussed with Mu Zi with great interest, "Qiao Jingjia was burned to death, but this kind of old building has no fire protection layer, once there is a fire, the fire will spread and it will be difficult to control, I think other methods should be used." ”

Mu Zi watched the two men walk in, her breathing was suppressed, her chest was extremely dull, and she didn't want to participate in this kind of discussion at all.

She even wondered if Mu Zening was deliberately deceiving herself? Otherwise, why did he say that those two men who were not good-looking were Murong Cheng's subordinates?

"I think we should use poison." Mu Zening continued, "Xiao Wanwan is an addict herself, and occasionally she overdoses and dies accidentally, which will not arouse anyone's suspicion...... Or it's not bad to burglary, but Xiao Wanwan probably doesn't have much money now, and even if she has money, she will immediately use it to buy drugs......"

Mu Zi couldn't hear what he was saying, and her heart was very confused.

Is this Mu Zening's prank?

Or is Xiao Wanwan really inside, facing a life and death crisis?

At this time, the two men came out of it, got on a motorcycle, and quickly left the alley.

Mu Zi couldn't hold back any longer, opened the car door and rushed out, heading straight upstairs to Xiao Wanwan's room!

The structure of the old-fashioned building is simple, Mu Zi quickly ran up to the third floor, and couldn't tell which room Xiao Wanwan lived in for a while, she stood in the middle of the aisle, looked left and right in a panic, and finally ran to the easternmost side!

The door was closed and not locked, Mu Zi twisted the handle, and as soon as she pushed the door open, she saw a woman curled up on the floor, her body was spasming, and she couldn't stop convulsing!

"Xiao Wanwan!" She exclaimed.

Mu Zi immediately took out her mobile phone and wanted to call the emergency center.

A hand reached over and gently lifted the phone from her hand, Mu Zi was taken aback, and turned to see Mu Zening who came over.

"She can't be saved." Mu Zening said lightly.

Mu Zi's face turned pale, gritted his teeth and said, "Then call the police!" ”

"Call the police?" Mu Zening seemed to hear a particularly ridiculous sentence, "The police came to ask, how are you going to answer?" Why did you come to Yutong Street? How did you find out about Xiao Wanwan's death? Do you see suspicious people coming in and out? ”

Asking questions one by one, Mu Zi froze in place.

Mu Zening put Mu Zi's mobile phone into her jacket pocket, took out a tissue, wrapped it around the doorknob, gently wiped off her fingerprints, and then slowly closed the door.

Mu Zi was stunned and watched the door gradually close......

He was right, Xiao Wanwan was hopeless.

Xiao Wanwan spat out white foam, and the skin of her bare arms was bruised and covered with bruised pinholes.

On the floor, there were also overturned syringes and pill bottles.

If the police came, they would only think that it was an accident caused by an overdose of drug addicts, but if Mu Zi was here, he would not be able to justify himself and arouse suspicion.

Mu Zening grabbed Mu Zi's arm, took the sluggish Mu Zi away from the place of the incident, and returned to the car.

The old building still had people coming in and out from time to time, but the people were indifferent, and who would have noticed that the occupants of the third floor had died? Maybe...... It won't be until the day the landlord demands the rent, or until the corpse emits a foul smell, that no one will notice the abnormality.

Mu Zi sat in the heated car, as if sitting in an ice cellar, her hands and feet were frozen stiff, and she didn't know where to put them.

Mu Zening found a telephone booth nearby that was some years old, and it could still be used after the coin, he called the police, and then drove out of the alley.

Yutong Street, where fish and dragons are mixed, no one knows that they have been here.
