Chapter 3032

Schiller arrived in front of the classroom where the incident occurred.

This is a very long corridor, but there are not that many rooms, because the left side of the corridor is the power distribution room for this entire floor. The scale of the power distribution room is very large, which leads to only three doors on the left side, which are the front and back doors of the power distribution room and a door to the utility room.

On the right side are two classrooms, one larger and one smaller, occupying two-thirds and one-third of the area respectively.

At both ends of the corridor, one side is the stairs, and one side is the elevator.

This structure is very strange compared to modern buildings, but after all, this is the Mercury base, and it is still the Mercury base designed by Stark. The meaning of full technical content is that besides technical content, it contains nothing else, so the building structure might be a bit strange.

Mainly, this thing was actually not completely built for living people. The main force working on Mercury on the Marvel side is still robots. Most rooms only conform to robot logic, and that robot logic is naturally the more straightforward the better, which leads to the structure becoming like this.

The person died in the small classroom.

When Schiller arrived, several professors had already waited in the large classroom with another batch of students.

This was originally not a classroom, but a laboratory. The so-called large classroom is the main body of the laboratory, and the small classroom is the observation room, so there is a piece of glass between the two.

Now standing in the large classroom, one can see the situation in the small classroom. Schiller walked through the crowd to the glass and saw a humanoid creature with light blue skin dead by the wall on the side opposite the glass.

The cause of death is clear at a glance. There is a very obvious penetrating wound on her chest. The wound directly penetrated the heart, a large amount of blood flowed out from the wound, and the corpse just lay crookedly in the pool of blood like that.

That is an Atlantean.

Arthur is popularizing the types of Atlanteans to other students. Schiller listened a little, and it can basically be summarized into three categories.

Ancient Atlanteans have completely gone extinct, but there are indeed some that are similar to ancient species left behind, usually the product of close-kin marriage. Their appearance is similar to humans, and most can use ancient divine power. This part of the population is scarce, and perhaps there are only a few hundred in all of Atlantis.

The second type is the mixed-blood of Atlanteans and humans like Arthur. After all, humans have occupied the continent for so many years, and the sea race inevitably deals with them. Even if they oppose intermarriage with humans, it is also very difficult to completely prohibit mixed-bloods like Arthur. They can also live in the sea or on land, and the population is relatively small.

And among Atlanteans, the mixed-blood of ancient Atlanteans and the sea race is the most numerous. Back then, Atlantis sank into the sea, and the closest to the sunken Atlantis were various sea race territories. Naturally, it was the near-water tower that got the moon first. The main body of Atlantis residents is such mixed-blood.

And because most indigenous sea races look relatively strange, the main body of residents also looks like everything. Human body with fish tail, human body with snake tail, with scales, with gills, with a turtle shell on the back, skin blue, green, yellow, black, purple, it is simply all-encompassing.

This Atlantean who died this time is a sea race mixed-blood, possessing light blue skin, ears that look like fish fins, but no fish tail, but legs like humans. According to the gender classification of the sea race, it is a female.

According to Arthur, her name is Bonu, and she just happens to be the daughter of a sea race general in the territory of his fiancée Mera. Her grades have always been excellent, especially good at controlling water. This time, she also stood out in the grand selection of Atlantis and came to the Mercury base for study.

Subsequently, Bruce introduced more details.

The body of the sea race is different from humans, and the time of the victim cannot be judged by rigor mortis. Even if it is left here like this, the corpse will not become stiff.

However, according to Arthur, the time for the blood of the sea race to coagulate is about twice that of humans, which means that under normal room temperature conditions, the coagulation time is about 20~30 minutes.

When Bruce and the others arrived, the blood had not completely coagulated, but it was already close to coagulation, which means the victim was murdered 20~30 minutes ago.

The camera in the room is broken.

It was not destroyed by external force, nor was it damaged by parts. Bruce checked it later and found that it was a short circuit in the internal circuit. The time of the failure is estimated to be an hour ago.

Which means that the monitoring in the room did not capture what happened in the room within this hour.

The monitoring outside the room, the monitoring in the walkway corridor and stairwell can only capture the situation on the side of the large classroom door, and cannot see what happened at the entrance of the small classroom where the crime scene is.

The monitoring in the elevator can capture what happened in the elevator and at the entrance of the small classroom, but once the elevator door closes, it cannot capture the door of the small classroom.

The time for the elevator to arrive and open naturally is 20 seconds, which means that within 20 seconds of the elevator arriving and opening, it can capture what happened at the entrance of the small classroom, and it cannot capture it when the door closes.

Everyone in Schiller's classroom has a sufficient alibi, but it just so happens that the remaining half of the people are taking Victor's physical activity class today.

The content of the activity class is to explore pressure and deformation. Victor requires every student to find an item they think is the hardest within 20 minutes after the class starts, and the scope is not limited to the classroom.

Which means the students are like pigs out of a cage, can go back to the dormitory to get it, can go to the laboratory to find it, and can even ask the professor for it. In short, they opened the door and scattered out without a trace.

This floor is naturally also within the search scope of the students, but because it is relatively far from the classroom where Victor is, most students did not come here to search.

Since there is a majority, there must be a minority. According to other monitoring cameras, there are still a few people who came, including the victim Bonu.

The remaining few are Claude, a student of the Gotham Academy of Magic, Ted, a young superhero Blue Beetle, a Mexican young man Gonzalez, a pair of Atlantean sisters Lali, and Jenna's brother Zan.

Now these few people have been taken to one side separately.

The monitoring on the elevator shows that Bonu came out of the elevator and entered the small classroom. She was the first person to arrive on this floor, but the other few were not slow, and all arrived in the following few minutes.

Hearing this, Schiller had a basic concept.

First is that there is actually a monitoring blind spot in this long corridor—in the case of the elevator door closing, at the entrance of the small classroom, nothing can capture it.

Coupled with the fact that the camera in the small classroom is broken, it belongs to no monitoring from the entrance to the inside.

But theoretically speaking, there is no monitoring blind spot.

Because if you walk up the stairs, you will inevitably be captured by the monitoring inside the stairwell, and if you take the elevator, you will inevitably be captured by the monitoring inside the elevator.

Which means both ways of going up and down the stairs can actually capture people, and there is no way to sneak into this corridor silently.

Of course, it is also possible that a magician used magic to teleport before, but because a student of the Academy of Magic was stuck in the wall because they were not familiar with the terrain of the base and were interfered with by other energy of the base, the use of teleportation is strictly prohibited within the entire base.

Although the verbal ban is of no use, after all, except for the camera in the small classroom being broken, the cameras in other places are not broken. If you want to teleport, you must have a starting point. The camera at the starting point will capture you.

The entire base has an artificial intelligence butler. Once the camera captures you teleporting, it will report to the police, but no alarm sound was heard within an hour.

However, in the case of the elevator door closing, the entrance of the small classroom is indeed a blind spot, then there might be other blind spots in the base, which requires all students to take out their alibi of not being in the monitoring blind spot.

According to the report of the artificial intelligence butler, all students did not enter any monitoring blind spot during the time period of the crime, all were active within the monitoring of the base, and no one teleported.

Why else would one say monitoring is good? This can basically rule out the suspicion of the vast majority of students.

Then actually, in the case that the monitoring of the corridor and the large classroom are both working well, the few people who came to this floor should also have an alibi.

But it just so happens that the monitoring camera in the small classroom is broken, and these few people have all entered the small classroom.

Actually, it is not any special reason, but because this floor's classroom is not used, it has a lot of sundries, which most students know. They feel that there are many things here, and they should be able to find things they are satisfied with, so they take turns coming here to rummage.

Bonu was the first to arrive, so she entered the small classroom first to rummage, and then immediately after, she went to the large classroom to rummage, perhaps because she didn't find anything satisfactory in the large classroom, and returned to the small classroom.

Among the suspects, Blue Beetle, the Atlantean sisters, and Jenna's brother Zan all went to the large classroom after getting out of the elevator. After rummaging, they didn't go to the small classroom at all, and walked directly from the stairs at the other end.

And Claude and Gonzalez, these two people, had the same action route as Bonu, entering the small classroom first, then entering the large classroom. However, neither of them accompanied Bonu to return to the small classroom, but took the elevator and left after coming out of the large classroom.

Anyway, to put it simply, no one's action route completely overlapped with Bonu's. They each also said their own ideas for finding items and the items found. After inspection, no problems were found.

Everyone's confession timeline also matches, meeting or leaving can corroborate each other, and at the same time, it also matches the monitoring screen of the large classroom or the corridor.

This means a famous scene appeared, which is a locked-room murder case.

Some people might want to say, didn't Gonzalez and Claude also enter the small classroom? How can this be considered a locked-room murder?

But the problem is, after they entered, they left before Bonu, and the elevator monitoring camera also captured them getting on the elevator. After getting on the elevator, all action trajectories can be checked, and there is no possibility of returning.

Which means, after they left, this small classroom became a locked room.

Then some people might still want to ask, they entered the elevator and left. Once the elevator door closes, doesn't the camera inside the elevator fail to capture the entrance of the small classroom? And I don't know if anyone entered.

The problem is that the elevator is occupied at this time. If someone wants to enter this corridor, they have to walk the stairs. There is also a camera in the stairwell. If someone enters the corridor from here, they will be captured.

Which means the scope of the locked room is not just the small classroom, but this corridor with this classroom.

Of course, it is indeed possible that someone used invisibility magic, but don't forget, there are no ordinary people present. Except for that Mexican young man who is a human, the others have some housekeeping skills more or less.

Among them, Claude himself is a magician, and just like the principle of a stand user, if someone uses magic at such a close distance, he can feel it.

And he just happened to be the last person to see Bonu, which means before this, if someone used magic, he could feel it.

Besides, just like teleportation magic, if you disappear invisibly, you also need a spellcasting location, and it might cause the activity trajectory captured by the monitoring to be inconsistent. You can see that you disappeared out of thin air for a period of time in the middle, and then you will be discovered by the artificial intelligence butler immediately.

But all other students do not have such problems. The pictures captured by the monitoring are all continuous, and not even a second appeared outside the monitoring range.

This is very interesting, Schiller thought, these cases are much more complicated than he imagined.

And unlike the past, the complexity lies not in the state of the corpse, but in the entire timeline process. It has been a long time since encountering such a traditional murder case.
