When he heard the voice of the system, Cui Yu knew that he was being cheated by the system again. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

In advance, he only mentioned the victim's information in a small way, and then did not go into details, and only after taking over the task did he say the reward and punishment method for completing the task. Moreover, the mission gave too little information, only information about the victim, and the place and method of death, without mentioning any information about the murderer.

Too few clues are given, and it's an old case. Even if Cui Yu has special abilities, it is still too difficult to find clues and find criminals within a week.

But no matter how difficult it is, Cui Yu has to find the murderer and complete the task.

It's only a week, and every minute counts.

Jiangcheng University, whose full name is Jiangcheng University, is a national key university in Jiangcheng. The mysterious death of three junior college students five years ago had a great impact at the time, but in the end, there was no news, no murderer was found, and the case has not been closed, and it has become an unsolved case.

Cui Yu once again straightened out the information given by the system.

First of all, the three people who died, where they have a connection in identity, are all students of Jiang University, and they are all juniors. As for the three of them, whether they know each other or not, whether they are in the same profession or not, Cui Yu has to check this by himself.

This is the first point, the second point is the way of death, all three of them died in an element called **, which is a metallic element, white, and its compound is highly toxic. At present, the main use of this element is to make sulfuric acid**, which is a potent rodenticide. However, in addition to this use, the gaseous ** can also be used as a seismic agent for internal combustion engines.

That said, this element won't be hard to find.

The third point is that the three of them all died in the woods of Jiangda Houshan, and the place of death was the same. Is it because this location is suitable for throwing corpses, or is it ...... Has a special meaning?

So far, this is a clue that Cui Yu got from the information given by the system, and nothing else is known.

However, from these clues, it can also be inferred that the murderer must have been from this school, but the students are still faculty members, so it cannot be determined. In short, before the murderer was identified, everyone at the school at that time was suspicious.

After sorting out the message given by the system, the time limit given by the system is one week.

Without any clue, to find the murderer within a week, Cui Yu has no confidence in his heart. But no matter how difficult it is, you have to find the murderer.

According to the analysis of the thoughts sorted out before, first of all, Cui Yu needs to go to Jiang University to find the information of those people at that time, to see if they have any other connections besides being juniors, and whether they know each other.

Moreover, Cui Yu also needs to go to the place of death to check the small forest in the back mountain of Jiangda, but is there anything special about it, is it a special meaning, or is it ...... It's just a place to dump corpses.

The last thing he needs to know is the case file at that time, who were involved, the case is still unsolved, there must be some secrets involved, maybe someone investigated some clues at that time, which is very important.

The current era is the era of information explosion, and Cui Yu first plans to look on the Internet to see if there are any descriptions of the case at that time on the Internet.

Cui Yu turned on the computer, typed the names of the three people on the browser, and soon a line of messages popped up on the webpage, including news, forum posts, and so on. Of course, there are also pictures of three people who died at that time.

Luo Lihua, 21 years old, is a junior in the Department of Chemistry of Jiang University.

Chen Luotian, 22 years old, is a third-year student in the Department of Materials and Science of Jiangxi University.

Zhang Tinglei, 21 years old, is a junior student in the Department of Mechanical and Electrical Engineering of Jiangxi University.

On the surface, none of these three people have any connection, except that they are juniors, they are not in the same major. However, on a post that no one paid attention to, Cui Yu saw such a message that said: Luo Lihua, Chen Luotian, and Zhang Tinglei are all extremely outstanding students in their respective departments, and they once participated in a national-level competition together, which is an innovation competition, and the three of them participated together and finally won a bronze award.

That is, this is where the three have the same connection.

Kindness?

When the post was seen at the end, Cui Yu also saw the other party's inference, he thought that the death of the three people at that time may have come from the hand of one person, and that person was the one who competed with the three at that time, because the competition failed, jealousy and resentment were the three of them. As for who it was, the landlord of the post at that time did not name it directly.

However, this point is a very important clue for Cui Yu.

It was a bonus.

Cui Yu wrote down this clue for the time being, and then planned to go to Jiangda to investigate, and first see what was going on in the grove in the back mountain.

Although five years have passed, Cui Yu believes that there will be clues that remain.

With the 'Death Cloak', Cui Yu prepared to go to Jiangda to investigate something.

Jiang University is about an hour's drive from his house, which is a bit far. But in order not to leave any traces, Cui Yu couldn't take a taxi to school, and in desperation, in order to save time, he still took out the void breaking charm.

After putting on the 'Death Cloak', Cui Yu held the 'Sky Breaking Talisman' in his hand, and his figure disappeared directly into the house.

In the state of the 'Death Cloak', no one can see Cui Yu.

Jiangda's place is very large, but fortunately, Cui Yu has been here a few times, so he knows where the location of the grove in the back mountain is, and he doesn't need to ask the students in the school, and he can find the location of the incident with ease.

There is a path in the grove in the back hill, but at the front of the road, a fence is enclosed, and a lock is hung on the fence. In addition to these, there is also a sign standing next to it, which says that the road is closed and closed to traffic. Looking at the words written on it, and the rusty state of the fence, it can be seen that it has been some years.

Without paying attention to these things, Cui Yu jumped directly and vigorously, jumped over the fence of this meter and five heights, and walked along the road towards the back mountain.

The trail is overgrown with weeds, but not to the point where it is impossible to walk, and apparently there are people here who mow the grass and repair the road regularly.

Walking all the way up the path, after walking for a while, Cui Yu finally walked to the grove in the back mountain.

The grove is about the size of a football field and has a pavilion inside. The pavilion is in disrepair, overgrown with weeds, the roof tiles have fallen quite a bit, and there are traces of tatters everywhere.

Cui Yu's gaze skipped over the pavilion and continued to walk forward.

According to the online post, the place where the three people died was a small wooden house thirty meters further after passing by the pavilion. The bodies of the three were in the cabin at the time.
