"Brother, did you find anything?"
Ning Qiushui was silent for a moment.
"Remember that number behind us?"
After mentioning the numbers behind them, everyone who was shocked by the previous bloody scene finally remembered this thing that they had long forgotten.
"Actually, the first three doors are not difficult except for 'special circumstances', as long as you are a little more careful."
"When I discovered the numbers on our backs just now, I was wondering what the significance of this thing is. If it were just a number, the Blood Gate would not have left such a big wound on our backs to 'emphatically' remind us of the importance of numbers. sex."
"Then I compared our situation with the situation on the door. It happened to be eight people facing eight doors, so do we have anything in common with the 'people' behind the door?"
Ning Qiushui spoke eloquently, and everyone listened to his story attentively.
"The first thing is gender. This point can be eliminated. Yun Wei and I have different genders. If it were reversed, the deceased No. 7 "An Shi" and the father of the deceased No. 7 behind the iron gate "Li Fei Nan" would also be the same. Not on."
"Therefore, the gender does not correspond to the 'people' between us and the Iron Gate."
"After excluding gender, I noticed another point, that is, there were four teams of people entering the Blood Gate this time, and they happened to be in groups of two."
"Please carefully recall the numbers on yourself and your teammates who entered the Blood Gate together, and then you will understand when you look at the Iron Gate."
When everyone heard the words, they hurriedly followed suit.
After a brief review, they quickly discovered the key problem!
The numbers of the two people entering each hut are connected, which can correspond to the two iron doors in the four directions of east, west, north and south respectively!
"Ning Qiushui, you mean...the two 'people' behind closed doors in these four directions are also in the same team?"
With Ning Qiushui's prompting, Xu Gang seemed to have caught something very important!
"You can simply understand that they have the same purpose."
"Let's first assume that this inference is true, and then look at -"
"Both the nurse [1] and the deceased's sister [2] do not want the murderer to be caught."
"Superintendent [4] and the deceased's mother [3] hope the murderer is caught."
"The two patients [5, 6] don't want the murderer to be caught."
"The doctor [8] and the deceased's father [7] hope the murderer is found."
"Please note! The above situation is their initial mental state when we did not exchange any letters!"
"Now through several exchanges of letters, let's simply work backwards to determine whether the above inference is true or not!"
Ning Qiushui tried his best to simplify his thinking to everyone.
"First of all, the doctor and the father of the deceased must have hoped that the murderer would be traced at the beginning. We can clearly feel this through the reflection of the two subsequent letters '10 and 11'."
"But after the doctor checked the monitoring, he hesitated and began to have differences of opinion with the deceased's father... But this is something that happened later, let's not worry about it for now."
"Next is patient "5" and patient "6". Both of them probably don't want the murderer to be found. Let's talk about patient "6" first. He is a psychopath and wants to satisfy his morbid psychology through the current situation. , once the murderer is found and the matter is over, he will no longer be able to use this matter to blackmail the nurse or some insiders, so from his perspective, he definitely does not want this matter to end so soon."
"Next is Patient No. 5. The letter he responded to is very brief. Why is it short? It is because it is easy to make mistakes if you talk too much. Obviously he also wants to hide something. In this case, the only thing that can be hidden is The truth is revealed, and it can be seen that he also did not want the criminal to be caught so quickly."
"So looking at it this way, patients No. 5 and No. 6 have the same purpose."
After Ning Qiushui finished speaking, Liu Meng bit her lips and asked:
"That's not right. According to what you said, wouldn't there be a paradox?"
"The nurse at Gate 1 doesn't want the truth, but the deceased sister at Gate 2 wants the superintendent to find out the truth as soon as possible..."
As she spoke, cold sweat suddenly broke out on her back!
Liu Meng seemed to have figured out something. She slowly raised her stiff head and swallowed her saliva.
"You mean... that little girl lied in the letter, and she actually doesn't want the truth to come out?"
The third letter on the table was written by the doctor at Gate 8. He had delivered this woman's baby once seven years ago.
I think the person who was born at that time was the deceased's biological sister.
In other words, the girl behind door number two is only seven years old this year!
"This... little girl shouldn't be the murderer, right? She, she is only seven years old, and she has no reason to kill her own brother!"
The fat man named Chu Liang felt inexplicably frightened by the idea that suddenly popped into his head!
A little girl who was only seven years old... strangled her newborn brother to death with her own hands?
"I'm not sure if it's her yet, but she's highly suspected, and she does have the motive to kill!"
Xu Gang took out the eighth letter on the table.
"The father of this family has a serious tendency to favor boys over girls. It is not sure whether the girl was despised or abused at home."
"If so, then she had a motive to kill her brother."
"Based on this, I agree with Ning Qiushui's point just now - for some reason, this girl really doesn't want the superintendent to find out the truth."
"She should know the truth, or she might be the murderer herself."
Everyone looked at the letter on the table and fell into silence for a while.
"So next, who should I send the letter to?"
Xu Gang asked this question.
It seemed like he was asking everyone, but also like he was asking himself.
He stared at the letters on the table, his eyes sometimes flashing with thinking, sometimes flashing with confusion.
At this time, Ning Qiushui, who was standing beside him, suddenly said:
"Do you dare to take the risk?"
Xu Gang turned around and looked at Ning Qiushui.
"How to take risks?"
Ning Qiushui said:
"You give a relatively dangerous letter to a little girl. If you survive, it means that our previous inference is completely correct."
Xu Gang's heart moved, and he understood which letter Ning Qiushui wanted him to deliver to the little girl.
"You want to hand the first letter to the kid at door 2?"
Ning Qiushui nodded and said very frankly:
"I can't determine the danger. If my previous guess is wrong, then you are at risk of being killed by her!"
"I am not qualified to force you to take risks for the benefit of everyone, so you can also choose to send a safer letter."
Xu Gang thought carefully about Ning Qiushui's proposal.
This is indeed a very dangerous behavior.
If their conjecture is correct, then the little girl at door No. 2 does not want the truth of the matter to be investigated. In this case, he gave Yunwei's letter to the little girl, indicating that he did not want the truth to be investigated. The little girl wouldn't have killed him.
But on the contrary, their inference is wrong. The little girl is very eager to find out the truth, so this letter will probably kill him!
Just when he was silent, Xie Cheng on the side suddenly took the first letter!
"Fuck, I'll do it!"
Xie Cheng gritted his teeth.
"...Lao Xu, go to the last door. I owe you a life. If I die, I will pay it back to you. If I don't die, we will be a big step closer to the truth!"
Xu Gang grabbed his wrist and shook his head slightly to signal him not to be impulsive.
"It's not yet to the point where we have to take risks..."
Xie Cheng replied:
"We are not the type of people who specialize in criminal investigation and reasoning. As time goes by, we still don't know what kind of dangers we will encounter later. The longer it is delayed, the worse it will be for everyone!"
"Have you forgotten what we went through at the first door?"
At the mention of their first door, Xu Gang couldn't help but twitch the corners of his mouth.
