"Christina, do you think you can find a way to arrange for all the people who come to the meeting to leave their rooms? Otherwise, you can just start the meeting. Wayne said.

"Direct meeting? But the personnel of the Federation have not yet arrived, and besides, it is not time for a meeting. "Christina seems to be in a quandary." What's wrong? Wayne. ”

"Two more planets were murdered, but they didn't die. One is the reptilian Sasana, and the other is the interstellar digger Gru. Wayne said.

"And both of these people also happened in the room, so I suspect that the killer might have some way to sneak into the room and then some way to sneak out. Also, the murderer should be a race with five fingers. It's like a human hand. Wayne continued.

"Okay, Wayne. I try to keep everyone together. The monitoring room contains information on all the races that have been reached, and you can check it out. However, the five-fingered race is not too rare in the galaxy. Christina went on to arrange her own business.

Jiang You came to Wei En's side at this time and said, "Wei En, have you found anything?" ”

"All the killings were in the room, and I don't know if there are any other commonalities," Wayne said. ”

"Come, Wayne. I've been here all the time, so I've kind of recreated what it was like back then. Jiang You pulled Wayne to the room of the Draco again.

The corpses of the Draconians have been taken away. And the original location of the corpse was drawn by Jiang You with a white liquid frame that he didn't know where to find. It really looks like a crime scene. And some other objects scattered on the ground, as well as things that are suspected of evidence, have also been drawn by Jiang You and numbered.

Seeing everything Jiang You did, Wayne said to Jiang You: "Shout, I didn't expect you to really have the ability to reason and solve cases." ”

Jiang You scratched his head and said, "Before becoming an astronaut in the Air Force, I went to a military academy, so there are also some courses similar to criminal investigation. It's kind of a little bit. ”

"Not bad, not bad. It turns out that this Conan is possessed by you. Say, what did you find? Wayne wanted to know what Jiang You had discovered.

But Jiang You frowned a little and said, "I found that it is not for the time being, I think it can almost restore the situation at that time." There are some things that I need to discuss with you. It still feels a little weird. ”

"You come here." Jiang You half-crouched and pointed to a small puddle of blood on the ground and said.

This bloodstain should have been behind the head of the Draco before, and it should have been in front of the head of the Draco at that time, so Wayne didn't find it before.

"The blood stain was very small, and it didn't come out. This is supposed to be caused by the Draco Star God slamming his head on the floor after he fainted. Jiang You pointed to the bloodstains and said.

"And if such an impact is formed, the Draconians will be at least at this altitude." Jiang Youyou stood up and pointed to a tree branch in mid-air in the room of the Draco Star and said.

The branch was about the same as on Wayne's chest, which was about a meter six in height.

"Look, there's a scratch of a claw here. It also shows that the Draco people used their claws to grasp this position before. And the scratches are messy, which seems to be caused by struggling. Moreover, if you look at this scratch, it seems to be very forceful, it should be a violent force caused by suffocation. Jiang You continued to explain to Wayne.

There had been a simple autopsy on the Draco before, so Wayne also knew that the Draco should die of suffocation. When suffocating, the person will shake strongly, and there may be convulsions all over the body, and incontinence. It seems that this Draco people will do the same when they are suffocating. Moreover, there are obvious white-green water traces on the branches, and Jiang You also thinks that it should be urine stains.

"And after the Draco people suffocated and fainted, there should still be some consciousness, so, look here." Jiang You pointed to the position of the foot of the white line of the corpse indicated by the Draco Star Man. There are also some scratches on the ground here. It should be suffocated with the paws of the feet.

The scratches on the ground are lighter. After all, although the room decoration is according to the branch-like design that the Draco people are used to, the floor is still made of relatively hard materials. What kind of material it is, Wayne doesn't know. It should be similar to a harder material such as stone or steel.

"You see, the Draconians were originally squatting from the branches, and then fell backwards. Fall to the floor this position. After that, he didn't move his position again. It feels like you're being strangled in the back. I've examined the corpses of the Draconians before, but I haven't found any signs of strangulation around their necks. This is a doubtful point. Jiang You said.

"And the Draco people are squatting on the branches, they should be looking at the white cube given by the Neon people. So, the cube was thrown here. Jiang You pointed to the white cube on the ground, then picked it up and showed Jiang You the falling process.

The white cube appears to have been broken apart. The middle of the cube is empty. The cube wasn't that big, and Wayne was holding one palm right in the middle. Moreover, this thing is very light. The white shell on the outside is very strong. The part that is broken is just the seam of the cube. The exterior of the cube is engraved with something like the molecular code of neon and some simple greetings from the neon people.

"So the situation at that time can almost be restored. The Draconians crouched on the branches of the trees to watch the Neon gift. Because the footprints in the room were already messed up when we came, we couldn't find them. So, someone is either flying, or they are already tall. At a position of almost two meters four to two meters six, cover the mouth of the Draco or strangle his neck. Exhaust the Draconians to death. Then flee the scene. Jiang You made a concluding speech.

Wayne listened to Jiang You's summary. said: "I have seen the video of the Draco people before. No one entered or left the room. And from the time the Draconians entered the room until Christina found the body, it was almost two hours. In the meantime, where will the murderer be? ”

"All I can think of is invisibility." Jiang You said.

This kind of situation is certainly not found in the history of human crime, but in a group of aliens, it is probably very likely.

"Then if it's invisibility, will it be the room that follows the Draconians into the room and kills people. Wait for someone to knock on the door, become invisible again, and then blend into the crowd and leave? That's Wayne's guess.

Wayne continued: "There is one more circumstance. When I was in Sasana's room earlier, I heard Gru shouting for help. Then after entering Gru's room, Gru said he saw a dark shadow. But when I chased it out, I didn't find anything, which is in line with the stealth guess. And Gru's neck has ten finger strangulation marks. ”

"In that case, it would be invisible, and then there would be ten fingers like a human. And the height should be more than two meters. Or will fly. Is this what a murderer should look like? Jiang You said.

"I think it's about the same, let's go to Christina and ask. After all, she is more familiar with aliens. Wayne said.

The two of them saw Christina again, and after listening to the analysis of the two people, Christina said: "In this case, almost only Draco can be considered a match. And the Draconians would never be able to kill their ambassador. ”

This seems to be at an impasse again. If these are in line with this, according to Christina, only the Draconians do. If the Draconians were going to kill their ambassadors, why would they attack the Pleiades, as well as the Reptilians and Gru. What is the connection?

Wayne decided to take a look in the surveillance room to see if he could find the dark shadow Gru was talking about. And Jiang You, at this time, went to the place where the Draco people parked their bodies to see if they could find any clues.

Again came to the monitoring room. Brought up footage from Gru's room. Gru seems to have returned to his room late, and looking at the previous footage, the guy seems to be staying in every room, but that's normal, after all, the guy seems to be planning a charity party, presumably for publicity.

And after Gru entered the room, it was very fast. Wayne saw himself knocking on Sasana's door. Seeing himself at this time, Wayne felt as if he was a little stupid. I couldn't even think of such a simple thing as pulling the door.

And Wayne entered Sasana's room and saved Sasana, and the two of them quickly came to Gru's room. And the door to Gru's room never closed. In the midst of this, Wayne did not notice any dark shadows in Gru's room. Perhaps, Gru hallucinates because of the lack of air. Wayne can only explain it this way.

Just when Wayne was in the monitoring room. The ambassadors of the planets, who had been organized together by Christina, were seated in the conference hall at this time. That's what Wayne came up with. At least together, the murderer should not appear in public.

At this time, there was a voice in the conference hall. And this voice is in the language of the earthlings.

"Hello ambassadors. Allow me to communicate with you in this way. I have taken control of the entire conference space, and you are still my valued guests. I didn't ask for much, it was something I wanted. ”

On the screen at the front of the conference hall, some characters appeared. It is also written in the words of the earth. And what this person wants, it's also very simple. It is a copper coin issued by the Galactic Federation. This copper coin can be used throughout the Galactic Federation, and of course, it needs to be exchanged with the Foreign Affairs Bureau on Earth.

And these copper coins, if you talk about purchasing power, I am afraid that you can buy a small planet. It's small, almost as big as the Earth. Underneath the copper coin, there is also a secret account number. And this account, as long as you hold the account card, you can exchange copper coins, and there is no record.

The kidnappers seem to have thought through everything.
