"! These scum of society, how could they have such a smart mind? Absolutely impossible, there must be something wrong with this. Pen ~ fun ~ pavilion www.biquge.info" Li Jiayu shouted angrily.

"The problem is that the murderer is out of your control, and I have deduced the original 303 murderer's murder steps. Originally, your plan was to have 303's murderer walk downstairs from the room to 203 downstairs around 0:00 last night, and in the process of their game, kill the man in 203 downstairs, which is a simple and crude murder case that leaves no clues at the murder scene, but because your plan is to leave no clues, this just leaves a chance for the real murderer behind the scenes. Li Zhitong analyzed.

"No way, I've already threatened the woman next door, there's no way she's out of my control!"

"The facts have been put in front of you, the woman who was supposed to be the murderer of 303 sprayed a strong perfume last night, but the deceased of 203 downstairs did not smell of perfume, which is enough to show that the woman of 303, who was originally going to be the murderer yesterday, did not go downstairs at all."

"But at midnight I heard someone walking outside, and there was a slight sound of going downstairs."

"That must be the real murderer, but the woman of 303 was in 304 last night, and she only returned to 303 when it was almost dawn, and the two women of 303 and 304 were all killed, and all of you are in the control of the real murderer behind the scenes."

"Don't talk nonsense...... No one can control me, only I manipulate other people's shares, these scum of society, I will get rid of them one by one, I want to purify this rotten society, so that those who have no morality will all become a mess of meat. ”

"Crazy, you should go for a psychiatric evaluation."

"Anyway, the game continues, and now you still have to continue to solve the case, and find out the murderer, and then I'm going to kill the person who used me with my own hands."

"It's not difficult to find out the real culprit, you checked in here last night, what time was it at that time?"

"Around five o'clock in the afternoon."

"That's the time to get off work, haven't you been out of the room all the time?"

"Nope."

"If someone goes upstairs outside, you're supposed to hear it, right?"

"You don't need to ask about this, I know what you want to know, around seven o'clock last night, the people 303 and 304 next door went upstairs and returned to the room one after another, and I only heard the footsteps of these two people, and they were all women's footsteps."

"Then you can be sure, the woman in 303 yesterday went directly into 304 after getting off work, but the person who went out of 303 in the middle of the night was not the tenant of the original 303, but the real murderer, that is to say, the real murderer was already hidden in 303 before you moved in, and now there are still two questions, the first is the footsteps downstairs in the middle of the night last night, can you tell if it is a man or a woman?"

"I can't determine, because I confessed to the woman who was supposed to be the murderer, and I asked her to take off her shoes and leave quietly."

"Then there is no way to lock the gender of the murderer, the second question is that after someone went downstairs yesterday, did you hear the footsteps of someone returning upstairs?"

"This ......" Li Jiayu was speechless for a while, carefully recalling the situation last night, but he couldn't remember whether anyone went upstairs in the end.

"Can't remember? Your observation skills and memory are lacking, but I think someone must have returned, otherwise the murderer would not have been able to kill the women of 303 and 304 next door, and the murderer only escaped before dawn, not long before I came here. ”

"That's someone downstairs."

"There's no way, I can only get to know the people downstairs, the second floor has already asked, let's go to the first floor first!"

Li Zhitong and the landlord's eldest sister explained their origins, and when the landlord's eldest sister saw Li Zhitong's showdown, her emotions instantly couldn't hold back, and the horror she tried her best to hide it was also revealed.

"You don't have to panic, with me, there will be no problem, now I want to find the murderer, please think back to the situation last night, whether anyone on the first floor has ever been upstairs." Li Zhitong said comforting the landlord.

"I don't remember, I was so scared all night, but if you ask me to think about it, I'm a little uncertain, because the room on the first floor doesn't have a private bathroom, so someone might pass me by in the middle of the night and go to the public bathroom on the inside of the stairs."

"So that's the case, then it can mean that every tenant on the first floor may have committed a crime, take me to get to know the people in each room!"

The first person to be questioned was Room 101, which was close to the door of the corridor, and as soon as the door was opened, Li Zhitong smelled a pungent smell of garlic, and it was the kind of garlic that ate too much garlic and smoked the room into garlic from his breath.

The landlord and Li Jiayu retched at the same time, but Li Zhitong was very indifferent, Li Zhitong, who had usually seen various crime scenes, already had resistance to anything disgusting.

The tenant of 101 is a relatively obese young man, the room is very sloppy, and the uneaten dumplings and garlic sauce are still on the table.

"Police, there were three homicides upstairs, please cooperate with the investigation." Li Zhitong took out his ID and said.

"Come in and sit?"

Li Zhitong inspected 101, there was no place to stay, this person's sloppiness made Li Zhitong breathtaking, Li Jiayu on the side had already clenched his fists, and that kind of hatred was about to explode.

"Exclude! He is not a murderer. Li Zhitong slammed the door and said.

"You can't tell he's not a murderer without asking him?" Li Jiayu asked.

"Quite simply, the disgusting smell of the snort in the room has already eliminated him, because if he hadn't been in the room all the time, the smell of the snort wouldn't have stayed in the room for so long, unless he stayed in the room all the time to create the garlic smell."

The second person who was questioned was a female student in room 103, the female student who opened the door looked very polite and very delicate, through inquiry, the female student's name was Zhao Yue, a student at a nearby university.

"You live alone?" Li Zhitong asked.

"Occasionally, boyfriends will come." Zhao Yue's voice was very small, and he sounded soft, which was in stark contrast to the tone of Li Zhitong's high-spirited female man's speech.

"Aren't you going to class today?"

"I only have classes in the afternoon, and I rest at home in the morning."

"Do you know all the neighbors here?"

"There's nothing to do, we'll say hello when we meet."

"What brand of perfume do you use?"

"Huh?" Zhao Yue was stunned for a moment, and then replied, "I don't use perfume." ”

"Can I go in and see your room?"

"Please!"

Zhao Yue's room was very clean, but because of the old house, it still looked a little dirty, and there was a simple bookshelf in the room, which was full of mystery novels.

"Like reasoning?"

"Just love to read."

"You're still a collector, and every set of novels is a complete set, and there are unopened books in it, so you must have read it and bought it for collection, right?"
