When Ziwu realized this problem, it was already too late, the person who lived in Xie Bei's house had already escaped, and even if he left some traces, it was very difficult to track down the other party, because behind the other party was the Night Apostle.

The Night Apostle seems to have a supernatural ability to foresee the future, always knowing the outcome of what is about to happen before it happens, and based on what he knows, he can prevent problems that may expose him in advance.

In this way, even if the police found some clues about them from their escape routes, it would not be of much use, because it was impossible to find any other clues other than the information they had deliberately left behind to Ziwu and the others.

However, no one is perfect, no one is absolute, and this time, the people sent by the Night Apostle turned over a question that could expose them all to the police, and they could clearly see that there was a note in the nearby grass at this moment.

The note read: The day after Xie Bei's death, go to Y's house, and kill Y before the police have investigated Y.

When they saw this letter, Ziwu and the others already knew when the next victim that the other party was going to kill would be killed, so that Ziwu and the others could find someone to go to the ambush in advance, and as soon as the person appeared, they would immediately arrest him.

But now there is a question, who is this Y? If the other party directly hangs his name, then Ziwu can let Wang Jin directly match it with the ticket purchase information in the playground, but what does the next letter mean now?

Whether they are talking about the code name of the operation to kill the other party, or whether Y is a location in their plans, these are the current uncertainties, so there is a good chance that they will miss this opportunity again until they figure out the problem.

At this moment, Ziwu and the other members of the crime team were anxious like ants on a hot pot, with beads of sweat the size of beans hanging on their heads, and they were trying to think about what this so-called Y was all about, what did it mean!

"Team leader, why don't I check the past cases again, maybe there can be some detailed data for our reference?" This is the biggest development of his own utilization value that Wang Jin can think of at present, and Ziwu immediately agrees now.

In addition, the others were still sitting in their chairs and thinking blankly, and Ziwu's mouth was still chanting the names of several victims: Wang Lixue, Jing Zhan, Xie Bei and this Y, who is this Y, and what does it have to do with these people?

Could it be that after thinking about it for more than an hour, Ziwu suddenly thought that this would be an order of twenty-six letters, and arranged the twenty-six letters with Wang Lixue as the origin, and included them in the seat.

In this way, is it possible to connect the victims? This idea is obviously not valid, because there are only 19 seats on this huge Ferris wheel, how can all 26 letters be included?

However, this immature train of thought naturally helped Ziwu to mobilize another idea: "Could the other party be using the order of the initials of each person's name to kill someone? Let's think about the name of each victim." ”

"The first victim Wang Lixue is the first letter, the second victim Jing Zhan is the first letter of J, and the third victim Xie Bei is X, so is this Y also the first letter of a person's name?" Ziwu analyzed in a low voice at the moment.

And then Wang Jin immediately launched a detailed investigation based on Ziwu's inference, and finally learned that among all the objects of attention, there are two people with the first letter of Y, one is called Yang Yun and the other is Yan Fei.

Two people, a man and a woman, one in the east of the city and the other in the west of the city, gathered more than 20 kilometers apart, and the only thing that could connect the two of them was the so-called playground.

Why do two people not hesitate to spend more than ten kilometers of construction to play in a playground? Besides, it is understandable for Yang Yun to come to this place, after all, there is only such a playground within Yang Yun's living range, but this Yan Fei is different.

There is a small playground near Yan Fei's home, although the scale is not particularly beaten, but the amusement facilities in it are not less than those in the city center, and many people near the west of the city will choose to relax in that playground.

But this Yan Fei actually traveled more than ten kilometers to this place to play, which is a little unworkable in some ways, but this problem still has to be explained by herself, after all, this kind of problem is not something they can limit.

What if people are in a bad mood and happen to want to go to the playground to relax, so they get on the bus and go to the city center?

Therefore, at present, the people of the crime team went to the playground first to get the ticket that Yan Fei used when she went to the playground that day, so as to remind the other party of the play a few days ago, otherwise, if the other party does not admit it, the case will not be able to continue.

Now Ziwu and the others must ensure the safety of everyone, at least they can't let the two victim targets who finally came out in advance be harmed, so Ziwu and the others arranged the police near Yang Yun's house first, and then went to Yan Fei's house.

On the way, Ziwu was still recalling the content written on the previous note, which mentioned that the day after the victim Xie Bei was killed, let the killer kill Y, why the next day instead of following closely?

According to the way they commit murder, it is not a problem to kill five people in one night, so why kill people the next day?

That's right, Ziwu thought about it, the reason why the other party let the killer attack Y the next day was because the place where Y lived was far away from the victim Xie Bei's home, and if he wanted to arrive after killing Xie Bei and disposing of the tools, it was likely to be the next day.

Therefore, if you count according to the information given on the other party's note, the next victim is likely to be Yan Fei.
