Ying Yu carried the cicada wing sword and protected Xu Rui in front of him, but Xu Rui gently pulled him behind him, looked at Liu Haofei who was injured and fell to the ground and shook his head.

"You don't think you're showing your feet, but I think you're full of flaws."

Liu Haofei's pupils shrank: "How is it possible?" ”

Xu Rui sighed: "I really didn't guess that it was you at first, but you shouldn't, you shouldn't, you shouldn't be clever in front of me."

On the day of the haunting of the Tang Mansion, the cloister was empty, and we could only hear the footsteps and the sneer of the female ghost, but we didn't see anything, and under normal circumstances, we couldn't determine her location at all.

But when your voice fades away, you say, 'She's gone,' and in a very affirmative tone, indicating that you either can see where she is, or you don't know what is going on. ”

As soon as these words came out, Liu Haofei was shocked and laughed self-deprecatingly: "Details determine the success or failure of the case, I didn't expect that I played eagle all my life, but in the end I was pecked by the eagle." ”

Xu Rui ignored his self-deprecation and continued: "If it were just like this, I might still think that you found out something, but the later murder case in the closed room made me sure that you were a mole." ”

"Oh? What else did I do wrong? ”

After the initial shock, Liu Haofei's mood has gradually stabilized, he knows that this incident revealed that he will definitely die, but there is no gain or loss, and he is very curious about how Xu Rui solved the case.

Xu Rui said: "You made at least two mistakes.

First, the doors and windows were locked at the time, and you were the first person to enter the room after the servant kicked the door open, but you, as an old criminal, did not examine the body immediately, but stepped aside and stayed where you were.

At first, I thought you were shocked because the scene of the crime was similar to the situation at the time of the Tang Mansion's destruction, but when I cracked the murder method, I realized that you used your body to block the most critical physical evidence.

Second, after I discovered the projection technique of the female ghost, I asked Jinyiwei to find the first mirror, and I could find the true location of the female ghost by following the refractive angle of the mirror.

At that time, you took the initiative to ask Ying to find the mirror, but when you came back, you told me that you didn't find it, and there is only one possibility, that is, the mirror has been discovered by you, but you hid the mirror and lied to me.

That alone is enough to prove that you are a mole! ”

Liu Haofei leaned against the wall with difficulty, ignoring his still bleeding legs, and instead clapped his hands with "pop".

"Wonderful, but I have a doubt, how did the murderer kill people? It's the kind of killing method that doesn't leave any internal or external injuries. You don't have to look at me like that, I'm only responsible for wiping their butts, and I really don't know how they kill people, I'm really curious. ”

Xu Rui stared at him for a moment, and when he saw that he looked hopeful, not as if he was fake, he continued to explain.

"It's simple, because they used something that I didn't think there would be in this world."

"What's that?"

"Ether!"

"Ether?"

Liu Haofei frowned: "What is ether?" ”

"It's a creation of my master."

Xu Rui didn't know how to explain chemistry to him, so in order to save time, he had to continue to pour dirty water on Guiguzi.

"Ether is a colorless and transparent liquid, which is highly volatile, and a person will quickly lose consciousness after inhalation, and if inhaled in excess, it can lead to death.

The deceased in the Tang Mansion extermination case were very strange, they seemed to die instantly, and there was no trace of resistance, at first I didn't know the reason, until the autopsy found that several corpses had exactly the same red spots, which was an allergic reaction to ether.

If the thing that kills is ether, then everything makes sense.

Feng Jin once mentioned that there was green smoke coming out of the backyard of the Tang Mansion on the day of the incident, and it was speculated that someone was lighting the stove, but the next person was not allowed to enter the backyard, so it was Tang Jiuguang himself who lit the stove, what did he want to burn when he lit the stove?

Also, the curtains used in the Tang Mansion are extremely thick, except for the doors and windows of the place where Tang Jiuguang, Mrs. Tang and the personal maid died, all the windows in other places are wide open, what is the reason?

If these doubts correspond to ether, they can all be solved.

In fact, there was no murderer in the Tang Mansion Destruction Case, Tang Jiuguang has been persecuted by the mastermind behind the scenes, and in the end he was cornered, so he had to use his life to cover up a certain truth.

So he asked his family to replace them with thick curtains that were not breathable, then closed the doors and windows, and then personally lit something containing a large amount of ether, smoked the whole family to death, and finally hanged himself.

The ether attack was very fast, and the family would follow Tang Jiuguang's series of abnormal orders even if they were suspicious, and before they could find out that something was wrong, they would fall into a coma, and then slowly die, so that they would not leave any traces of struggle or resistance.

If my expectation is correct, the reason why the doors and windows of the rooms where the other dead are located are wide open is a good thing you did.

You were the first to rush to the scene of the crime in the name of investigating the case, and the murderer didn't know if there would be any residual ether at that time, so he would definitely explain to you in advance to open the window to avoid accidental injury.

The doors and windows of the room where Tang Jiuguang died were closed because he hanged himself, and there was no need to do anything more.

The doors and windows of the Zen room in the backyard are also closed, because Tang Jiuguang hung them on the beams after stuning his wife and maid, and he must have opened the windows to ventilate before doing this, so you don't need to open the windows again.

When you arrive at the scene of the crime, in addition to opening the windows to ventilate, you hide some things, probably the same thing as in the murder room that you blocked with your body and then quietly hidden, which is a small stove for burning ether.

You solve the last flaw for the murderer, and the magic of this female ghost killing will become weird and seamless!

Oh yes, why did the murderer kill the surviving maid, and I also probably know the method of murder in the secret room.

First, since Tang Jiuguang killed the whole family with his own hands, the surviving maid was naturally deliberately left behind by him, and in order to prevent Tang Jiuguang from leaving behind, you had to kill her.

Second, as a witness to the crime scene, if she says that all the doors and windows of the room were closed at the time of the crime, there will be flaws in the murder of the female ghost you deliberately created.

So you can't let the surviving maid go anyway.

As for the method of murder in the closed room, it is actually very simple, someone has already prepared a furnace for burning ether in the corner of that room, and then you send someone to bring the maid to that room, and then find an excuse to explain that the servant inside locks the door and lights the stove.

I guess the excuse you use is also very simple, which is to tell the officer who protects the maid that the murderer is at large, and that he must lock the door when he enters the house, and then tell him that there is a stove on the ground, which can repel mosquitoes when lit.

The officer naturally didn't suspect you, the immediate boss, so he killed himself, but in fact, the murderer never entered the room from beginning to end. ”

Xu Rui finished his words in one breath, but he was not at all relaxed in his heart.

With the technological level of this world, ether should never appear, and now someone actually uses ether to kill people, it means that there are other traversers nearby, and they carry a large amount of ether with them, or have mastered the technology of making ether.

There is an even more terrifying possibility, that is, there are many otherworldly technologies in this world that no one knows about.

reminds me of the English that appeared in the small box left by Yang Weiyuan: "Target No. 3 Zhu Zhen, male, thirty-one years old, Fengyang Xiucai, tried and failed, crossed over here in 1640, and paid attention to a high level." ”

Could it really be that someone is hiding in some dark corner watching all this?

The more Xu Rui thought about it, the more chilled he became.

At the same time, after listening to Xu Rui's explanation, Liu Haofei's face turned pale, as if he was deeply shocked, and it took a while before he came back to his senses.

"You are terrible, if I hadn't experienced many details personally, I'm afraid I would never have imagined that you could say that you scored exactly the same based on some details alone."

Liu Haofei sighed from the bottom of his heart, but as soon as the words came out, he shook his head with a smile.

"It's a pity, even if you can find out the murder case, you still can't find the real culprit, not to mention that you can't crack the code on the ledger, the second white cloth has also been dealt with by me, even if you have great ability, you still lose, hahahaha."

As he spoke, Liu Haofei suddenly laughed nervously, and his face turned red.

Xu Rui looked at him with pity, shook his head and said, "I'm sorry, I'm afraid I've disappointed you again this time." ”

"What?!"

Liu Haofei's laughter stopped abruptly, and he looked at him in shock and said, "Have you found out who is behind the scenes?" That's impossible! ”
