Lie Yu scratched his head a little embarrassed, and said, "It turns out that you have already investigated in advance, it is indeed me who made a fuss, sorry~"

Adaki didn't bother with him anymore, "Heh, it's good that you understand, but I didn't say you, Lie Yu, do I look like that kind of reckless person? Generally doing this kind of secret latent investigation, doing a good job of investigation in advance, designing a good course of action, and leaving a way out are all necessary matters, and I am more familiar with this aspect than you, so you can ask questions later, but definitely don't question my professionalism, ok~"

In the end, Ai Daqi's expression, which was originally quite gentle, faintly showed a cold sense of oppression, which suddenly made Lie Yu stunned in place, and he couldn't help but say embarrassed

"Ugh...... When, of course, ok~"

"Phew~ Count you to each other, okay, we've wasted a lot of time, it's time to move on to the next step."

Lie Yu said, "Then our next step is to go to the scene of the maid case, you wait a while, I made a magic mark there, wait for me to sense it, it will be fine immediately."

And just as he was about to cast a spell induction, Idaki rejected him, saying, "Hey, Lie Yu, have you forgotten? We've got the map, so we don't need your magic to find a place, and I've probably found the location of that room on the map."

"Hey, so fast! Where is it?" Lie Yu was slightly surprised

"I'll see, this is the room, huh?"

Ai Daqi was suddenly stunned in the middle of her words, but soon she raised the corners of her mouth slightly, and said inexplicably, "Oh, interesting~"

Lie Yu frowned and wondered, "What's the matter, what did you find again?"

"Ah, nothing, I've found the location of that room, but it's a coincidence that it's also on the third floor, and it's right next door to us."

As she spoke, Adaki pointed to the next room on the third floor where the two abrupt red dots were located, and the layout looked like a study.

"Well, is that a coincidence?! But next door, is it on the right or on the left? From here, it looks like it's on the left." Flame Feather pointed to the map

But Adaki corrected, "It's on the right, the direction and orientation of this map are wrong, so it's fundamentally opposite to the environment we are in now, you have to adjust the perspective to the map to work."

With that, Ada turned the map in a different direction and deviated a few degrees to the right, until the map overlapped with the real space, and the study that Lie Yu was looking at on the left suddenly changed to the right.

"Oh, it's really on the right, so without further ado, let's hurry up."

"Hmm"

Adaki replied simply, and then she said to Rita, "Alright, Rita, you can put the map away."

"Okay"

Rita immediately turned off the projection function, and the three-dimensional structural map disappeared in place in an instant, and then she shrunk her body in a circle, and then very consciously snapped back to the groove on Idaki's belt.

Lie Yu and Idaqi walked to the right wall of this room one after the other, and after Idaqi groped on it twice, he picked a random place to open the teleportation channel.

A black hole with purple light and a little fluorescence appeared in front of the two of them in an instant, and Lie Yu immediately stepped into it when he saw this, but at this time, Idaqi stopped him

"Hey, wait, you're just going to go straight to it?"

"Well, otherwise, anyway, almost no one comes to this floor, it doesn't matter if you hide or not, and we both hide our own things, and no one can see anyone at that time, and we are simply blind." Lie Yu shrugged his shoulders as he spoke.

But Adaki was unusually serious at this time, and she said, "No, Lieyu, you're just letting your guard down like this."

Lie Yu was puzzled, "Ah, it's not like that, is it?"

"Don't be careless, if you're not absolutely sure, the simpler it is, the more cautious you have to be, although according to the map it is true that there are no people on this level, but everything is afraid of the unexpected."

Lie Yu looked at Idaqi's serious expression and was shocked

A little stunned, in the face of her unobjectionable attitude, Lie Yu could only compromise

"Ah, okay then, but how do you solve the problem of not being seen?"

"It's true that it's a bit of a problem for each of us to be invisible to each other, and I don't want you to sit on me a second time."

Lie Yu was speechless and paused for a moment, and said a little speechlessly, "Hey, can you stop mentioning this stubble~ But in fact, I have a way to solve this problem, which is ......."

Before Lie Yu finished speaking, Ai Daqi was immediately interested when he heard that he had a way to solve it, and directly interjected, "Oh, there is a way, you didn't say it earlier, what can you say?"

"Hey, can't you listen to me, ha~ Forget it, the operating principle of my cognitive obstruction is actually to compress and diffuse the magic into a shape similar to cloth, and then cover the body of the caster to form a protective film, so as to distort the outside world's impression of the caster, so as to achieve the effect of invisibility."

Idaki was a little impatient and said, "Talking about the point~".

"Ahem, don't worry, I was just about to get to the point, the point is that under normal circumstances, if I want to cast cognitive blockage on multiple objects, it will form multiple covering films to distort cognition, but if I stretch this covering film large enough to cover multiple objects, it is equivalent to treating multiple objects as one individual, so that both of them can be invisible and can see each other at the same time."

Hearing this, Ai Daqi's eyes lit up and praised: "Hey, this idea is good, if you use reality as an example, it is equivalent to a child playing hide and seek, two children hide under the same piece of cloth, so that the ghost can't see them, but they can see each other, there is a good way not to say it earlier, don't use it quickly."

Idaqi urged, but at this time, Lie Yu was a little embarrassed: "But this method has some drawbacks, first of all, because we are placed under the same membrane, its size has a limit, so we can't be too far apart, and because of the size of the extended coverage, it will consume more mana, and the use of the line of sight will be shortened from the original one hour to half an hour."

"I don't care about the distance, but it's only half an hour's time, so I can investigate a ghost in such a little time, don't be kidding~" Idaki complained with a little disgust.

Lie Yu was a little speechless and said, "Hey, who's kidding! This is also something that can't be helped, okay~ You think I'm happy, it's very convenient to use magic, but the more convenient it is, the more restrictions there are, and it's rare for a magician like me to cast spells without chanting complicated spells and holding complex rituals, okay, where can you find such a convenient partner as me."

"Ah, okay, okay, then we'll use your magic when we encounter any sudden situation, let's get down to business first."

With that, Edaki passed through the black hole in one step ahead of Lie Yu, and Lie Yu, who was one step later, whispered a word of complaint before passing through

"Ha~ really, I've never seen her like this."

After that, Lie Yu also stepped into the black hole, and soon in just a second, Lie Yu passed through the wall through the black hole of Idaqi and came to the study next door, which was also the location of the maid case.

When he actually entered the room, he found that Adaki had already set up the lights, and saw a strange metal luminous object glued tightly to the chandelier, filling most of the room with warm lights.

The light is just right, much dimmer than normal indoor lighting, but it's enough to see things and not too eye-catching, and the heavy curtains are closed so that you can't see the inside from the outside.

At this time, Ai Daqi was looking around the desk near the window in the room, although the police protected the scene of the case, but it has been so long since the case was closed, and the signs laid at the scene have long been removed by the police, but there are still many traces left.

For example, the white tape specially used to identify the corpse, although it was also torn off, the stickiness it left and a lot of dust stained it, so that the place where it was glued and the rest of the floor formed different shades of color.

It's not very clear about the staccato pieces, but if you look closely and put it together with your eyes, you can see the general outline of the human form.

There was a large brown blood stain on the head of the silhouette, and its position was right on the right leg of the desk, and Adaki looked up to it, only to see that the corner of the desk directly above the leg was stained with blood that had also turned brown.

And this corner of the table is more seriously damaged than other corners, and there are small traces of dotted blood stains in other places such as the tabletop, and it is obvious that the maid who died in an accident died because her head hit the sharp corner of the table, which does look like an accident.

Seeing that she had started her investigation, Lie Yu casually asked, "These are the traces left at the scene of the crime at that time, how is it, Idaqi, do you see anything?"

But Idaqi didn't answer and asked, "Lie Yu, I remember that my first impression of this maid case seems to have been learned from LaBel, but because I wasn't interested at the time, I didn't know much about this case, so how much do you know about this case?"

"Ugh...... I guess I know a little bit more about this case than you do."

"yes, so it looks like you've already investigated?"

Lieyu replied, "Sort of, but I was forced to know, because I heard most of the things from LaBel, you know, since you didn't show interest, LaBelle transferred his desire to talk to me, and he told me about the case whenever he had time, which really annoyed me."

Idaqi was a little speechless when she heard this, and said, "Since you don't want to hear it, then you reject him, why do you have to cooperate with him?"

"Heh, I don't want to be you, but before I refused, he was already talking about it, so I didn't have a chance to refuse, so I could only listen to it~" Lie Yu shrugged his shoulders very helplessly.
