"It's reasonable, but this explanation is not enough, but it is in line with the cause of drowning, I will continue to listen, Xiao Yao, you continue." Yan Guanghai held his chin thoughtfully.

Xu Yueren shook his head sadly: "No, this way is too cruel, is this still something made by people?" ”

Qin Lanzhi said: "Niu Xi and Elizabeth died too miserably, compared to this murder, the first few killings were 'pediatric'. ”

Xu Yueren said: "Yes, the first few times I killed people, I don't know how painful the deceased was during his lifetime. But this time, the insects gnawed and the pool was alive...... It's scary to think about. ”

Fang Yao said: "Even if it is terrible, even if it is inhumane, even if the great pain of being killed can be felt, no matter how strong the moral condemnation, all of this must be said after the truth is revealed!" ”

"So far, the huge glass sink has been upside down and drowning Elizabeth alive, and as long as the sink is still at the bottom of the pool, Elizabeth's body will not be able to surface."

"Therefore, another secret can be reasonably explained - 'When the lights were on, the reason why Chu Ying did not witness the floating corpse was because the sink had not been destroyed at that point in time.' ”

"So, combined with the information we investigated before, the moment the sink dehydrated out, remember, this incident happened at that point in time before the black light, and attracted the attention of at least me and Chu Ying!"

"Then, almost without a moment's interval, the lights went dark, and then we heard the sound of glass shattering!"

"But in fact, the moment such a large sink comes out of the water, the 'sound of water coming out' should be fresh in my memory."

"The reason why the 'sound of water out' was ignored by us was that the noisy player sound brought by the black light muffled and disturbed the sound of water coming out of the water that was not obvious in the distance!"

"So, with the 'sound of water', it also explains the faint water stains on the ground, of course, because the water droplets will soon dry up and disappear, and the moment the lights are on, everyone is still in a trance."

"So when Guanghai finished investigating Zhu Shao, he reacted to this situation, and I thought of this."

"I think Chu Ying should have heard the sound of water coming out more clearly, but it was fleeting, and the darkness that followed made everyone's nerves go crazy, who would have thought of such a detail?"

"Don't worry about it, the sink jumped out of the pool and collided with the big chandelier, but the gorgeous base of the chandelier is too familiar, and the heavy sink is also broken!"

"Fortunately, the sink retains its 'four corners', so I can deduce what kind of vessel it is."

"That's how Elizabeth died, by and large, the body never floated. Elizabeth's body was indeed able to float slightly, but it was pressed against the base of the inverted sink. ”

Xu Yueren said: "Fang Yao, you have once again solved the murder incident that I can't think of an answer to after racking my brains, it's really amazing." ”

Qin Lanzhi also sighed: "Since I got acquainted with you, I found that my horizons have also broadened, and my world has become broader. ”

Yan Guanghai didn't relax, he continued to ask: "Fang Yao, what you said is right, but I still have one last question, that is, the sink is such a 'behemoth', why didn't Chu Ying, who was closest to the first crime site, find it?" ”

"Could it be that Chu Ying is the murderer?"

Fang Yao said: "This is a very simple theory of optical refraction. First of all, the glass sink itself is 'integrated' with the color of the water, so it is inevitable that Chu Ying will miss it, even if it is caught with the naked eye, it will not feel suspicious. ”

Xu Yueren nodded again and again: "Wow, I seem to have understood what is going on." ”

Qin Lanzhi was confused: "Fang Yao, let's talk about it, I still don't understand at all." ”

Yan Guanghai asked, "I'm sorry, I almost forgot the optical knowledge in middle school." Even if you see the sink upside down in the water for the first time, you can't react for a while. But a dead person so obvious is under the water, can't Chu Ying see it? ”

Fang Yao said: "Chu Ying really can't see the corpse!" Actually, I don't remember much about physics since I went to college, but this principle is too classic. It may be impressive. ”

"The sink is upside down in the water, the light passes through the water, and then through the glass, and the refraction declination occurs, then the secondary refraction, and then through the corpse, many times the refraction, many times to form the refraction declination, plus scattering, back to the retina ......"

"The corpses in the water have long been hidden by optical 'illusions', so if you look at it from a distance, you can't see what is inside the sink!"

"If you think about it, it's hard to see a sink from a distance, let alone a 'Phantom in the Water'? Inevitably, the corpse would have 'disappeared' in that case. ”

"The moment the sink dehydrated, maybe the corpse had already surfaced, but Chu Ying's eyes were first attracted by the sink, then the seamless black light, and finally the panic of everyone."

"What if the body surfaced, no one would notice it in the first place. I have to say that the murderer's layout and scheming are by far the strongest! ”

"However, as for who the murderer is, I mean who the murderers of the two murders are, I probably already have a judgment."

If this judgment is true...... It's just a matter of step-by-step, the process of unlocking the truth about Elizabeth's death is not over yet, and I need the last piece of the puzzle. ”

Yan Guanghai said: "The last piece of the puzzle is the rope. ”

Fang Yao said: "But first we need to find the purpose of the other end of the rope, if I remember correctly, a copper-colored thing flashed in my eyes before, it is near here, everyone help find it." ”

Her request was not difficult, the copper color was quite different between the glass color and the dirty mud black at the bottom of the pool, and soon, Qin Lanzhi found something "special." ”

A thing similar to an ancient jade seal, except that at the bottom of it, a piece of broken thick glass, was broken into an irregular shape that was ten centimeters in diameter.

The glass is mixed with a part of copper alloy, and the tip of the copper alloy is a round hole.

Fang Yao saw that this round hole was so familiar, and subconsciously passed through this round hole with his little thumb: "Huh? This round hole is the same size as the round hole system of the previous part of the chandelier? ”

Xu Yueren asked, "Is there anything to say about this round hole?" Look at this thing, it's probably part of the sink, right? ”

Fang Yao replied, "That's right, this is probably the inlay at the bottom of the special sink, which is upside down in the water and is threaded by something that resembles a tough rope. ”

"Then, docking the round hole on the side of the big chandelier, the two auxiliary murder weapons that are not related to each other 'one in the sky and one under the water' will be exquisitely combined!"

"It's really a bold and risky murder plan, I won't admire it, but I still admire it in my heart."

Xu Yueren said: "I understand, so the investigation is not over yet, and we must find the 'rope' that links the two auxiliary murder weapons." ”

Yan Guanghai said: "The biggest problem now is that there are no clues about the rope left at the scene. ”

Fang Yao sighed lightly, returned to Elizabeth's body, and held up Elizabeth's hand.

She saw the manicure that was worn out by the glass, and it was almost broken, which shows how painful Elizabeth was in life!

"We're nodding friends, Elizabeth, and I'll let you go." With that, she gently closed Elizabeth's eyes with her hands.
