After all, where have I seen you

Listening to Song Guo's words, Yang Mumu thought to himself that it was completely hopeless, no one saw what Huang Yin did.

Unexpectedly, Yang Mumu was still disappointed, Song Guo continued: "But, I found a hole in the wall on the right side of the window, through which I saw the villain!"

Yangmumu, keep your eyes open! "Did you see it?"

"Ok!"

At this time, they came to Building No. 2 unknowingly. Yang Mumu pulled Huang Yin and stepped on the weeds under the eaves, and quickly moved to the window of the room where Nurse Liu lived. There was an empty bed inside, and no new arrangements had been made. people stay.I moved a few steps to the right, and I saw a hole. Three bricks in the wall were removed, just like the "windows" used for ventilation in the bathroom in the countryside, but they were obviously opened very high, otherwise it would be dangerous for Nurse Liu to take a bath.Yang Mumu measured it with his eyes, and not only could he stand on tiptoe, he couldn't see the inside, but he couldn't see it even at the height of the pine cone.

Yang Mumu pointed at the hole, "You said you saw Huang Yin through this hole?"

Pinecone nodded.

"But it's so high."

Pinecone pointed to a big tree behind them. "I climbed a tree to watch."

Yang Mumu felt that she had caught something, she looked around, took a deep breath after making sure there was no one there, and asked very carefully: "Then what did you see?"

Song Guo answered Yang Mumu's question unhurriedly, "I saw that the villain had bags on his hands and feet, and a mask on his face..."

Yang Mumu guessed that Huang Yin was trying to prevent fingerprints and footprints from being left behind, and that he was wearing a mask because... afraid of being recognized?Absolutely not!Afraid of being poisoned!It must be, for something so poisonous as alcohol, if you inhale a little bit of volatilization, you will feel dizzy for a long time.

"...He first removed the bathing thing, then poured some white things into the pipe, and then covered the round lid..." Song Guo made gestures while talking, Yang Mumu understood what he meant, he meant The sprinkler for showering and the water pipe connecting the sprinkler.

"Hmm...and then?"

"Then, as he stepped back, he poured a bottle of water on the ground."

"water?"

"Uh-huh!"

Yang Mumu frowned and thought, water?No!It must not be water. What is like water?And what's that white thing that's poured down the sprinkler hose?

Yang Mumu bit her finger and thought.The white solid was poured into the water pipe, and the water-like liquid was poured on the ground. When Nurse Liu was taking a shower, she turned on the water valve, and the hot water passed through the sprinkler pipe to wash over the white object, flowed to the ground, and mixed with the "water" on the ground. Together...Yang Mumu suddenly raised his head!She thought of it, the white solid poured into the hot water pipe is potassium cyanide, and the "water" poured on the ground is sulfuric acid!

Although Yang Mumu is a scumbag, she likes to watch, especially after arriving in the United States, she is lonely and has nothing to do. Her hobby is watching movies to pass the time. Qinghua potassium is the favorite method of killing among all detectives. It is fast. !There is no cure for it!Seeing these chemical things, Yang Mumu would google it. She remembered the form of potassium cyanide, white crystal or powder, easily soluble in water, and it will quickly produce highly toxic hydrogen cyanide gas when it contacts with acid.so……

That night, Nurse Liu, who didn't know it, closed the bathroom door as usual, took off her clothes and was about to take a shower. She was even thinking about the pine cones sitting outside.However, Song Guo had already been pulled away by the rushing nurse Zhang.She turned on the water valve, and the hot water flowed through the potassium chlorate. The potassium chlorate quickly merged with the water, flowed through the water pipe, and fell from the sprinkler to the floor. The floor was full of sulfuric acid. Potassium cyanide reacted quickly with sulfuric acid, and soon, hydrogen cyanide gas filled the entire bathroom. When she felt something was wrong, it was too late. Hydrogen cyanide quickly entered her lungs through her airway, and she felt difficult to breathe. Grabbing her throat, she quickly opened the bathroom door, but it was too late. In less than a minute, she didn't even step out of the bathroom, and fell to the ground.

The hot water has been flowing, flowing, flowing all night, washing away everything, the potassium chloride in the water pipe, and the sulfuric acid on the ground. Can't find out.

If the pine cones hadn't been seen, how could the police find out that this was the way of committing the crime?Even if it is guessed, there will be no evidence.The way he kills is just perfect, this man is terrible.And how did he get potassium chloride?Where did he get his sulfuric acid?

Yang Mumu stood there unknowingly for a long time, Song Guo tugged at her sleeve, "Sister, sister..."

"Uh..." Yang Mumu finally came back to his senses.

"Songzi, since you saw it, why didn't you tell others? Did you tell the police?"

Song Guo shook his head, "I climbed on the tree and saw the bad guy go out, so I wanted to go down and follow him, but I didn't expect me to look down. Nurse Liu happened to be staring at me pretending to be angry under the tree."

"Nurse Liu?"

Song Guo lowered her head, "She said that I peeked at her bathing, and threatened me that she would lock me up. I couldn't argue with her, he said he would tell other sisters that I have a habit of peeking at women taking a bath. I want to explain, she Said she was busy, and asked me to go to her room at night to explain slowly. Then, she left, and I kept thinking about how to make her believe me. But I was afraid, because sister Nurse Zhang told me, never Don't be alone with Nurse Liu, she will bully people. I don't know what to do, but at night, Nurse Liu took me to her room and asked me to explain clearly. But I just arrived in her room and haven't spoken yet. Just touched me with her hands, I was very uncomfortable, and then she said that she was going to take a shower, and asked me to wait for her to come out of the shower before listening to my explanation. Not long after she went in, there was a knock on the door outside the house, and I went When I opened the door, I found that it was Nurse Zhang’s sister. She dragged me away in a very angry manner. She reprimanded me along the way and said that I could no longer be with Nurse Liu like this. Seeing that Nurse Zhang was so angry, I didn’t dare to say a word. Nurse Liu died two days later, and I never had a chance to explain to her that I didn't peep at her taking a shower."

After hearing this, Yang Mumu couldn't help sighing, if Nurse Liu hadn't had those crooked thoughts, perhaps the pine cone could have saved her life, and she would have committed the crime herself.But not necessarily, that cunning demon wanted her life, and he could escape the first time, but he couldn't escape the second time.
