"Are you crazy? That elevator can only carry 45kg of things, this woman said that she has 46kg, how to transport it? ”

Su Yong, who had just treated the wound and had gauze wrapped around his face, felt that this statement was too nonsense, and tried his best to refute it.

Song Xiaofang did not rush to explain this problem, but continued to explain the murderer's methods

"I just said that the murderer put Yalan in the warehouse around the corner, where very few people go, plus now there is a corpse in it, and no one will go there, so no one will find out that Yalan is hiding there, after the murderer killed people, he went back to the warehouse on the first floor and put Yalan in the elevator, and then walked to the second floor again and called the elevator up, and the elevator on the second floor is not far from the door of No. 82, so the time to wait for the elevator plus the time to carry Yalan into room No. 82 should not exceed 30 seconds, In line with what you said, no one went upstairs for more than a minute. ”

"Papapa

"Hahaha, it's really a reasoning, but you still didn't say how to use a 45kg elevator to transport a 46kg person up."

was praising Song Xiaofang, but his tone and demeanor were full of mockery, and Su Yong was also waiting for Song Xiaofang to make a fool of himself as if he was watching a good show.

Song Xiaofang said categorically

"How can the weight be so accurate, not to mention that this elevator can only carry 45kg, maybe more than 45kg, not to mention..."

Song Xiaofang walked to Su Yalan's side and casually pulled up a lock of her hair

"You see, Ara's hair has obviously been cut, so I guess..."

At this time, Song Xiaofang also saw the "traces of being bitten by vampires" on Su Yalan's neck, and was also startled and hesitated for a few seconds.

Su Yalan looked up at Song Xiaofang and asked suspiciously

"What's wrong?"

Song Xiaofang's hand shook inadvertently

"No, nothing."

He went on to explain

"So I guess it should be that when the murderer put Yalan into the elevator, he found that she was still a little overweight, so he cut off some of her hair."

"Hahahahahaha..." Su Yong let out a burst of laughter as if he had heard the funniest joke in the world

"You still don't believe that you're crazy, a few hairs can make up for the weight of 1kg?"

Song Xiaofang didn't argue with him, and said it directly to everyone

"It doesn't make sense to say anything else, seeing is believing." As he spoke, he turned his gaze to Su Yalan

"Let's put it to the test now!"

Everyone came to the elevator, Song Xiaofang opened the elevator, gently hugged Su Yalan in, stroked her hair and comforted

"Don't be afraid, Yalan, it'll be fine in a while."

Su Yalan nodded, closed her eyes, and greeted the coming darkness.

……

"Hehe, I thought you had a lot of skills? Do you think my means are that simple? Song Xiaofang, you lost. The murderer silently enjoyed the joy of this perversion.

"Toot! Honk! Honk! ”

The elevator door was not closed, overweight, Song Xiaofang was suddenly eclipsed, on the contrary, Su Yong broke out into even greater ridicule

"Hahahaha, I'll just say it, I'll say it!" As he spoke, he walked towards the table.

Song Xiaofang carefully took out Su Yalan, looking at Su Yong's back as he left like a victor, he didn't feel a trace of humiliation, more of a despair, the despair of not being able to prove Su Yalan's innocence.

Su Yalan leaned closer to Song Xiaofang and looked at him helplessly

"Little Fang..."

This kind of look made Song Xiaofang's heart as painful as a knife, and everyone returned to the dining table, Song Xiaofang didn't say a word, Su Yong kept shaking his legs on the side, looking at Song Xiaofang with a smug face, he now enjoys this feeling of being on top very much.

"The detective's reasoning is indeed interesting, but unfortunately, the real world is not the same as the fiction world."

After Han Chen sneered, he got up and prepared to leave.

"Wait a minute!" Yu Dongting stopped him, took out the rope at the scene of the crime, pulled it twice, and the rope broke with a "snap", and began to explain

"Did you see that? This rope is too brittle to strangle people at all, so this is not a murder weapon at all, Guo Xiang was really strangled to death. ”

Han Chenchen nodded pretendively

"Yes, yes, that's right, but it can't be proved that it wasn't that woman who strangled Guo Xiang's neck, right? Maybe she's just pretending to be soft and weak, but she's actually very strong? “

Song Xiaofang was in no mood to quarrel with them now, and kept his head down and was silent

"What's the problem, what's going on?" Ask yourself this question over and over again.

When Han Chen was about to go up the stairs, Xiao Yanran said timidly

"That's... I just found out that Yalan's neck seems to have been bitten by something, could it have anything to do with the case? ”

"What?!" Everyone felt very strange when they heard it, and they all came to Su Yalan's side, and Han Chen slowly stopped, turned around, and looked at them curiously.

Zuo Hongyi suddenly screamed

"Vampires! The teacher must be back! ”

Yu Dongting's brows furrowed and he said angrily

"Can you please stop being sensational here?"

But Zuo Hongyi had his own reasons for insisting and began to explain

"You think, if Guan Shuang didn't commit suicide, then only ghosts can freely enter and exit such a heavy gate, and now her neck has been bitten again, obviously a vampire did it, it must be the teacher, it must be the teacher is back! The teacher bit the woman, manipulated her, and made her kill for herself. ”

After speaking, he knelt on the ground and bowed to him

"Teacher, teacher, forgive us and stop killing people."

"Stupid! Calm me down! Yu Dongting scoffed at this nonsense and pulled him up.

Su Yong looked at Zuo Hongyi like this, and he was also a little stunned in his heart, but he was still trying his best to convince himself not to believe this kind of thing, and insisted that the murderer was Su Yalan

"Don't, don't talk nonsense, the murderer is this woman, as for how she made that secret room, when the police come, we will all know, and now the top priority is to lock him up!"

Song Xiaofang stood up suddenly, Su Yong thought he was going to do it again, and subconsciously stepped back, but Song Xiaofang came straight to Su Yalan's side and carefully observed the wound on her neck.

"I see! I know what's going on! ”

Han Chen said sneeringly

"The detective game is over, and your reasoning is wrong."

Song Xiaofang ignored him, but found a pen and paper, raised his head and asked everyone

"How much blood is the weight of a human body?"

No one understood what Song Xiaofang meant, and they all looked at him blankly, not knowing how to answer.

Seeing that everyone didn't respond, Song Xiaofang raised his voice and asked again

"How much blood is the weight of a human body!?"

"Ten, thirteen," Fang Xin replied tremblingly

After Song Xiaofang recorded it, he continued to ask

"What is the maximum amount of blood loss without life-threatening conditions?"

Xiao Yanran suddenly had a premonition that Song Xiaofang would find the truth immediately, and hurriedly said

"I know that about a quarter is the limit."

"Okay." Song Xiaofang didn't raise his head to calculate, and after ten seconds, he raised the paper in his hand

“46x1/13x1/4=0.885，46-0.885=45.115”

Su Yong asked after looking at it carefully a few times, and asked puzzledly

"What do you want to say?"

Yu Dongting understood what Song Xiaofang meant, and said in amazement

"I see, the murderer took Miss Su's blood and made her weight drop!"

"That's right!" Song Xiaofang took the case

"After the murderer stunned Yalan, he took out 1/4 of her blood, and then used the method I just said to commit the murder, but Yalan's weight was still a little overweight, so he cut off a lock of her hair to make up for the weight of about 0.1kg at a time!"

"I remember there was indeed a syringe in the warehouse." Lao Zhang said and ran towards the warehouse.

"I see, no wonder Yalan has been dizzy since she woke up." Xiao Yanran said, worried about Su Yalan even more, hurriedly ran over, and slowly helped her sit down.

Su Yong was also shocked by this reasoning, but he still said it stiffly

"Then why are there overweight now? If that's the way it goes..."

"You idiot?" Xiao Yanran deliberately interrupted Su Yong,

"Didn't you see two needle holes in Yalan's neck? Of course, it was the murderer who transported Yalan upstairs and injected the blood back. ”

Su Yong was choked and speechless, and Yu Dongting continued

"That's right, the time to wait for the elevator, the time to carry Miss Su into room 82, plus the time to inject blood, will definitely not exceed a minute."

Although this reasoning seemed to be flawless, Su Yong was still a little unconvinced

"Even if you say this method works, what evidence do you have to prove that someone actually used it?"

At this time, Lao Zhang ran back and shouted

"It's gone, it's gone, the syringe is gone."

"Now there is evidence, it should be that the murderer threw it into the river through the window after using a syringe on the second floor, so it should not be found, but it can be proved that someone has used this technique."

Song Xiaofang said confidently.

Su Yong completely admitted defeat and couldn't say a word, but Han Chen on the side said

"Even though we know the modus operandi, I'm still not sure who the killer is, right?"

"That's right." Song Xiaofang said, walked in front of Han Chen, did not escape his gaze at all, and declared loudly

"That murderer not only hurt Yalan's body, but also shamelessly tried to blame her, and caused irreparable damage to her soul, I swear with my man's dignity, I will find him out!"

"Little Fang, you're so handsome! Sister believes in you. ”

Han Chen glanced at Xiao Yanran, who was applauding next to him, snorted coldly, and turned around to go upstairs.

"Wait a minute." Song Xiaofang stopped him, turned around and asked everyone

"Is it still necessary to lock up Yalan now?"

After saying this, Song Xiaofang put his eyes on Su Yong, seeing that Su Yong was unnatural, he turned his head to avoid making eye contact with Song Xiaofang.

Han Chen said coldly

"Since she's not a murderer, why are you still holding her up?"

After saying that, he returned to his room.

Su Yong pretended to yawn

"It's getting late, I'm going back to my room to rest."

The two most radical people who want to lock up Su Yalan have this attitude, and as for Zuo Hongyi and the others, they won't say anything.

Xiao Yanran jumped up excitedly and hugged Su Yalan tightly

"Great, great, I'll just say it, I'll say that the little fang can return your innocence."

Su Yalan smiled, stared at Song Xiaofang with grateful eyes, and didn't say a word.

Song Xiaofang walked over and stretched out his hand to Xiao Yanran

"Thank you for always speaking for me and Yalan."

"Cut." Xiao Yanran pretended to be angry and grinned

"What? Isn't it time to scold me during the day? ”

Song Xiaofang lowered his head in embarrassment, not knowing what to say.

Xiao Yanran patted Song Xiaofang's shoulder like a female man

"Oh, just kidding, I'm going back to my room to rest, and your Yalan will be taken care of by you."

After speaking, he walked to the second floor with a big grin, and at this time Yu Dongting also walked over

"Little Fang, you have unassailable reasoning."

Song Xiaofang shook his head

"I always feel like this case is an impromptu idea."
