Xia Lingyao had long known that Qiao Jiaxi was going to plot against her, so she was on guard everywhere, and she found out that Qiao Jiaxi was adding a nameless potion to her beer.

Then I found out that everyone was making excuses to leave one after another, so I took advantage of Qiao Jiaxi's inattention and changed the beer.

After a while, half of the people had left, and Qiao Jiaxi really wanted to pour me wine, because I had already changed the beer, so I drank it at Qiao Jiaxi's request.

Immediately afterwards, Qiao Jiaxi glanced at everyone, and the rest of the people left, leaving only me and Qiao Jiaxi in the box.

When I saw that the situation was not right, I was ready to find an opportunity to escape,

Sure enough, everything was as I guessed, that nameless potion was not a good thing, Qiao Jiaxi felt a little unwell, kept rubbing her temples, and shook her head vigorously.

He seemed to be hallucinating, saying things like 'don't come to me' or 'I've already given you money'.

And he seems to have mentioned a name, as if it was the name of the girl who had gone crazy and committed suicide after being raped by him a few years ago.

I was so scared that I didn't dare to stay in the box any longer, so I hurriedly got up and left. As for what happened to Qiao Jiaxi, I don't know. ”

Xia Lingyao is a smart girl, and a self-loving girl, she did not succumb to Qiao Jiaxi's coercion and temptation, and used her wisdom to escape from the clutches.

Xia Lingyao's description is consistent with Yun Yichun's confession and the surveillance video in the corridor.

Could it be that Qiao Jiaxi really committed suicide because he had a ghost in his heart, coupled with the hallucinogenic function of the fragment potion, he hallucinated?

But what about the "Black Sunday" song?

Could it be that this case was a multifaceted factor that ultimately led to his suicide?

Same as Ning Xiaobai? Another suicide?

It can't be such a coincidence, right......

"After you left, was Qiao Jiaxi already in that hallucinogenic state?" Li Meng slowly opened his mouth and asked.

Xia Lingyao shook her head vigorously: "I don't know, he should have hallucinated at that time, as if he was crazy, so I ran away in a hurry." ”

"When you were in KTV, did anyone use a mobile device to transmit songs to the song orderer?" I took the conversation and asked suddenly.

Xia Lingyao looked at us in a daze, and shook her head slightly: "I didn't pay attention, there should be no one......"

Li Meng and I glanced at each other and fell into deep thought.

The successive suicide cases are too strange, even if the case is really a suicide, then where did the song "Black Sunday", which frequently appears at the scene of the crime, come from?

It seems that I should go and talk to Zhang Yajing.

Because the surveillance video shows that on the night of the crime, she also appeared at Marriott KTV, and stayed in the box of 312 for 20 minutes.

The criminal police team cooperated with the serious crime team to conduct a careful investigation and questioning of these 11 people, collected biological information, confirmed the signed records, and then let them go.

Except, of course, for that sissy agent, Yun Yichun.

We summoned Zhang Yajing in accordance with the law, and Zhang Yajing cooperated with us very much and went directly to the Ningzhou City Public Security Bureau for questioning and investigation.

"Where were you at ten o'clock last night?" I asked her directly.

Zhang Yajing was stunned for a moment, and then replied weakly: "I went to an interview last night. ”

"Interview? Where to go for an interview? I followed up with a follow-up question.

"Marriott KTV." Zhang Yajing said the name directly without thinking.

"How can you go to KTV for an interview?" I smiled wryly and said casually as if I didn't care.

Zhang Yajing looked at me in a daze, lowered her head a little embarrassed, and said in a deep voice: "I'm also very strange, I received a temporary notice at that time, and I didn't think much about it, so I went to see the situation." ”

After Zhang Yajing finished speaking, she told us the ins and outs of the whole thing: "I have submitted resumes to many music companies, although I am a piano teacher, I am good at arranging and writing lyrics, and I have also written some original songs. But all the resumes I have submitted are like a stone in the sea, and there is no news at all.

Last night, I suddenly received a reply from a company, saying that the company had read my resume and was interested in communicating with me further, and the general manager in charge of this aspect asked me to come over in the 312 box of Marriott KTV.

I thought it was strange, but I didn't think there would be any danger, so I went. I arrived at about ten o'clock, and there were so many people in the box that the general manager asked me to sing a few demos and then sat me down and waited.

During this period, the general manager Qiao kept pouring me wine and did something to me, I was very angry and left. ”

After listening to Zhang Yajing's description, everything is consistent with the evidence we currently have.

The case of Qiao Jiaxi's death should be that he drank the beer that was exchanged by Xia Lingyao, and the fragment potion reacted in his body, and then there was a hallucinogenic situation.

In the hallucination, he saw the female artist who committed suicide after being driven crazy by his unspoken rules a few years ago, fell into madness, and finally chose to commit suicide by cutting his wrists.

The only suspicion is the "death music" "Black Sunday" that appeared at the scene of Ning Xiaobai and Qiao Jiaxi's suicide at the same time.

But in any case, this magical song is at most the trigger for their suicide, not the direct cause. There is no way to use it as any substantive evidence.

After all, it can't be written in the closing report, they committed suicide after listening to the song "Black Sunday".

If I write like this, I will be scolded to death by Shen Ruoshan.

At this moment, I suddenly thought of something, and hurriedly asked Zhang Yajing: "You said that you sang a few original song samples at that time?" ”

Zhang Yajing nodded and admitted, "Yes." ”

"Did you use the mobile data transfer function of the song orderer?" I asked.

"Yes, I used this function to transfer the samples from my phone to the song ordering machine." Zhang Yajing looked at me and said lightly.

I frowned, took a deep breath, and looked at her earnestly.

Could it be that the song "Black Sunday" was really transmitted to the song ordering machine?

But Qiao Jiaxi committed suicide after twelve o'clock, Zhang Yajing left at ten twenty, and when Zhang Yajing left, no one else in the box left.

How did Zhang Yajing do it, when Qiao Jiaxi was hallucinating, she happened to play that song?

After investigating Zhang Yajing, there was no actual evidence or exact clues to accuse her, so she could only be allowed to go back first.

This is really an undocumented crime......

Just when this case was about to be characterized as suicide like Ning Xiaobai's case, there was suddenly good news from the Technical Investigation Bureau.

They copied the song from the song machine and found a big clue!
