Return to the hotel.

Ye Hao took a shower, flipped through the spare computer, and carefully checked the corner of the door or something, but the person who still didn't find "LEE" gave her a reward for clearing the second question.

Shouldn't they have been caught by her and repented?

Ye Xueba felt apprehensive for a rare time, but soon, she found that she was thinking too much: when she turned her head, a small drone was hovering outside the window of her room.

Ye Hao walked to the window, opened the window, and the little drone immediately flew over, knocking on the window edge with a "click": "Hey, baby, did you miss me today?"

Looking at this style of behavior, this drone is also a system equipped with a small robot, and it can be determined that it was sent by "LEE". Ye Hao grabbed it with her hands, flipped it over and looked at where it could hide things, the little drone stopped its wings and turned, and said shyly: "What are you doing, you will do something to others as soon as you come, I hate it~"

Ye Hao's hands trembled and said, "Believe it or not, I changed your voice program." ”

"Baby, you can't bully people like this," the little drone twisted and said, "If you want to change it, can you change me to a girl?"

"You're so cute, not suitable to be a girl," Ye Hao said, finding an embedded USB flash drive from its plane's belly, unplugging it and saying, "Okay, your mission is complete, you can go." ”

The little drone seemed very sad when he heard this: "Baby, can't I really stay?" LEE SAID, YOU NEED ME TO LEAD THE WAY IN THE NEXT TEST OF THE LAST LEVEL!"

Is this a small threat?

Unfortunately, she didn't plan to follow their script from the start. Ye Hao said: "I haven't seen anything yet, if you need it, you are welcome to pick me up." ”

After the answering procedure was over, the little drone had no reason to stay, and continued to say in a sad voice, "Okay, baby, see you next time, I'll miss you", while turning the propeller and flying away.

It's obviously a ruthless thing, but it can also calculate people's hearts, so what do those people who will have feelings for robots in science fiction movies think......

After Ye Hao finished complaining, she closed the window, closed the curtains, returned to the computer, and plugged in the USB flash drive.

The second level is broken, and there is probably a desire to solicit, and the things given by "LEE" this time are relatively core, and there are two videos of Rong Chengyue when the incident occurred on the USB flash drive.

The first section is from the time she gets on the elevator to the way she gets out of the elevator, and the direction in which she turned is to go to Ye Yi's room.

The second section is when she knocks on Du Lexin's room, but when she enters the room, the door is unusually open, when a waiter passes by, she calls someone in, and a few minutes later the waiter comes out and returns the same way.

The time of the surveillance video happened to be one before the crime and one after the crime.

But the most critical part is erased.

This is clearly telling her that they have things, just wait for her to get them.

Ye Hao tried to restore the cut part, but in vain, she showed an electronic ticket, a ticket for a luxury cruise ship to the Danube, and the boarding time was nine o'clock tomorrow night.

The scenery along the Danube River is good, but on the cruise ship, she is afraid that she will not be able to get down, after all, the international convention says that once the cruise ship enters the high seas, no one cares about the murder and crime.

Fortunately, she never expected these outlaws to make a deal with her in a proper manner.

People are in the rivers and lakes, who doesn't leave a backhand?

She went back and watched the video again, closed the computer, took out some preparation tools for the previous survey of the scene, and went out, Rong Chengjue had just finished taking a shower, wiped her hair and poked her head out of the master bedroom next door and said, "It's so late, where are you going?"

Ye Hao took out a bottle of 502 glue from the toolkit and said, "Go find A-Ying, there is something to stick over there." ”

"Looking for A-Ying again," Rong Chengjue muttered, but he was not embarrassed to say the words "I will go too", but said, "Then you come back early, I'll wait for you." ”

Ye Hao nodded, then took the door and called A-Ying to inform him to go back to the room, and like the night before, he took the elevator upstairs and arrived at the place where Ye Yi once lived.

After thinking about it, she returned to the door of the room where Du Lexin lived, and looked up, and there was indeed no surveillance camera installed in the hotel.

It seems that her previous observation was not wrong.

Closed his eyes and recalled the angle of video shooting, then opened his eyes, and calculated the height and position of the camera under the shooting angle, it happened that A-Ying also arrived, Ye Hao motioned for him to go back to the room and move a chair over.

A-Ying trembled and took the room card to open the door, didn't even dare to turn on the light, moved a chair and ran to her and said, "What are you doing here?"

Ye Hao stepped on the chair, looked at the decoration on the high place between the wallpaper and the elevator door, and said, "Check to see if there are any fingerprints here." ”

This position is much higher than the usual perspective of ordinary people, Ye Hao put on a white glove and touched it, and immediately there was dust on it, it seems that even if it is cleaning, it is rarely involved here.

A-Ying stood on tiptoe and said, "I can't see anything, what are you going to use to check fingerprints?"

"502 glue. ”

"Huh?"

Too lazy to explain this common-sense problem to the scumbag, Ye Hao took out the 502 glue from the tool bag, squeezed the cap of the bottle, took out another piece of filter paper, and evenly applied the 502 glue to the filter paper.

Then, she took out a humidifier with a Snow White pattern and a girl's hot electric heating rod, sprayed and scalded the filter paper, and tossed it for about five or six minutes.

A-Ying: I always feel that this set of tools is not very reliable, are you serious?

However, Ye Hao once again proved her strength as a scholar, and when she put away the toolkit and handed it to A-Ying, she carefully uncovered the filter paper with both hands, and two white fingerprints appeared on the light yellow wall wallpaper.

Ah Ying opened her mouth and stammered: "Ah, ah, there are really fingerprints, whose is it, is it the murderer?"

Ye Hao took out her mobile phone and took a photo, jumped out of the chair and said, "It was Rong Chengyue who hired the person to destroy the hotel's surveillance video." ”

"You mean the person who helped Rong Chengyue tamper with the surveillance after the incident?"

"No, not after the incident, but before the incident, there is one thing we expected wrongly, before the incident, the video surveillance of the hotel has been destroyed. ”

Rong Chengyue's desire to transfer Ye Yi's cash was premeditated. She placed an order on February 10 and transferred the funds on the afternoon of February 13, which is enough time for "LEE" to make many arrangements. Destroy the picture of this layer of video surveillance early, use a fixed image, or before the carousel, so that Rong Chengyue will not appear in the hotel's surveillance from beginning to end, isn't it much safer than deleting and tampering with the video afterwards?

As for why he installed his own set of cameras in one fell swoop, Ye Hao guessed, on the one hand, it was convenient to check the situation at the scene, and on the other hand, it was not without this as evidence, and he would throw it out to blackmail Chengyue at the right time - these "Internet mercenaries" have a reputation, and once they are entangled, they are not so easy to get rid of, and they will only fall deeper and deeper.

Rong Chengyue is really bold.

Also, if she wasn't bold, how could Ye Yi die, heh.

I don't know what she did in the room, but afterwards she was worried that someone would rescue her, so she called all the waiters who passed by in and sent them away, this alone is enough to show that Rong Chengyue is eager for Ye Yi to die.

"Then, what should we do now," A-Ying said in a panic, "Then there is still no video surveillance, how can we investigate, just let Rong Chengyue get away with it like this?"

Sure enough, as a person in the Internet era, looking for evidence or something, the first reaction is always all kinds of surveillance, video, recording, etc., "LEE", as a perennial cybercrime team, is probably also out of this kind of thinking, so that he will have nothing to do and run to the scene of the crime.

specially left himself evidence of the crime.

Of course, their carelessness also has something to do with the fact that this is only an online economic crime, not a human homicide case.

However, no one is innocent at this point.

Ye Hao took the toolkit from A-Ying's hand and patted it: "Who told you that the key to investigating the case is video surveillance, and in the era when there is no surveillance, don't the police investigate the case?"

Obviously, compared to surveillance, the more powerful evidence is the fingerprints of the crime, fools~
