"Yao Shenghai's behavior was not completely unexplainable before he woke up." Liang An straightened the cup, not cleaning the still warm water stains underneath, and looked down, "Since the only reason we have ruled out is cleaning. This cup The sealing strip may have been tampered with. It may be to promote aging, and some heating and other means are used to make it look like it is damaged by natural changes, but in fact it does not affect normal use. "
"Because Yao Shenghai works in an orderly manner and doesn't just place things randomly." Shao Zi frowned, "In other words, could this cup have been tampered with a long time ago?"
"It's possible, but not absolute." Liang An raised his eyebrows and picked up the cup again, "Then what we have to consider now is the cause of this dose that is neither embarrassing nor embarrassing. There is no doubt that if the murderer originally The purpose was to kill Yao Shenghai, so he failed."
Because Yao Shenghai is not dead.
But that's precisely the most surprising part. You know, it is not easy to obtain poisons like potassium cyanide. All poisonous drugs are controlled, even the parts used in electroplating factories will be registered. It's a hard question, but if such an elusive poison was available, how could something as simple as the dosage go wrong?
It's okay to sell the gold lunker. If this kind of thing is sold by lunker, it's really a small business with a lot of money, which is incomprehensible.
So maybe the problem isn't getting so much poison. But a sufficient amount of poison did not enter Yao Shenghai's body.
So, where did they go?
"If the problem lies in the lid of the cup, and the murderer wants to induce us to think that the incident happened during the performance time in the theater, then no matter what preparations are made, the event needs to happen regularly during the performance. And the theater is tilted at 45 degrees. The water cup slot is undoubtedly part of the mechanism. Taking advantage of the characteristics of it and the water cup cover, Yao Shenghai was forced to clean the cup after halftime."
The existing conditions stop there. Next, there is the link that has no evidence but something to rely on.
Fantasy, but not completely fantasy.
"So, what happened next was within the murderer's expectation, and what interfered with the final outcome of the murderer's crime?"
The first is the starting point of this mechanism-the source of poison.
"If the poison is allowed to enter the drink without touching the cup body, there is only one possibility - the poison itself is in the water cup, and only a certain action is triggered to allow it to be integrated into the drink."
And since the murderer made such careful use of the environment and objects, he must not have had any motive.
"If the poison is wrapped around the poison with something like glutinous rice paper that can melt in water, and fits it in the gap at the top of the inner layer of the white lid of the water cup, it may not be easily detected."
The amount of potassium cyanide required is really small, so this tiny device can be as miniaturized as possible. The sticky rice paper used for wrapping may even be less than the size of a fingernail.
What triggers the mechanism is water - or in other words, liquid.
If you need to clean the drink on the cup body, you need to take the leaking cup to the sink steadily first, and use water to wash away the leaking liquid on the cup lid and the contaminated areas on the cup wall.
A drink that's loaded with sugar is bound to have a weird, slippery texture once it's leaked out and allowed to dry out a bit. Unlike when they were drunk into the mouth, the cleaning work at this time was really unpleasant, but had to be dealt with in time - because the feeling after drying was even weirder. Especially for those who are not at home but on the way out, this feeling is really unbearable.
The cleaning process is also quite easy to understand. The lid has been proven not to seal completely, so the cleaning process should not be done while the drink is soaked. From the beginning, the drink is poured out of the cup to facilitate the subsequent steps and cleaning of the outer wall.
And this kind of cleaning also has limitations. For example, according to common sense, the liquid on the cup lid will not be completely eliminated. Because Yao Shenghai only knew that the water cup was leaking liquid, but he didn't know whether it was because he didn't tighten it tightly or because of a problem with the water cup itself. Because of this, if he wanted to verify this situation, he would need to fill the liquid again and conduct the experiment.
For example, the water in the water boiler outside.
It is safe, hygienic, not raw water, and does not need to be washed after being filled - there is no need to use water to clean the water.
"This was the murderer's original plan. But if you look back, there is a loophole that is not easy to detect." Liang An said slowly, "This may be the reason for the error."
This plan seems to be quite complete, and it is not difficult to guess. Yao Shenghai travels in his own private car, and there is a flat water cup slot next to the driver's seat. The liquid in the water cup after drinking water is not easy to jump three feet high, and it happens to seep into the gap. But the process of washing the cups can erase this worry, just in time for Yao Shenghai to fall into the trap.
However, there is something else besides the transparent water glass and transparent air.
The invisible thing - in other words, it can see its companions, but it can also see itself.
"The water provided in the theater is boiling water. The water vapor inside will rise and leave its own traces on the cup wall and everywhere in the water cup." Liang An breathed a sigh of relief, "Luckily, the murderer may not have considered this factor. That's why Yao Shenghai was lucky to survive - because he happened to pour out the fatal drink with the highest potassium cyanide content. The murderer did not realize that the secret book of water vapor above hot water was attached to the paper and would react with the infiltration of water. The same effect. The poison was dissolved in the water vapor earlier, and the time was quite right."
The amount of water droplets on the wall of the cup is small simply because there are few grooves on which it can easily adhere. The large drops have been left along the wall of the cup without appearing to be a large amount remaining in the end, but in fact, the water vapor has been in such an alternating state of up and down for a long time.
It is enough to put poison into the drink when the dripping water droplets move.
Although Yao Shenghai, who was traveling in the afternoon, changed cups for the evening trip, he must have filled the water cup with hot water as always - even though the water cup itself was not insulated, the liquid inside quickly cooled down.
It was at this time that someone deliberately came into contact with this inconspicuous object. Considering the difficulty of committing the crime, the most ideal method would be to purchase a water cup of the same style as Yao Shenghai's spare water cup, and directly replace the lid of the water cup that already looks like a brand new one with another lid, thus achieving the goal in one step.
Of course, this is just speculation for the time being and there is no evidence.
The time when the murderer committed the crime has also changed because of this result. It was originally within a period of time during the whole drama performance, then expanded to after the water cup was dusted near Yao Shenghai's workbench for use, and now it has shrunk to today after Yao Shenghai set off. .
Because only at this time. If you step early, the long-term infiltration of water vapor after leaving the magazine will inevitably cause the glutinous rice paper to melt in advance, but if you step late, the result will be the current situation.
This is an extremely contradictory murderer with exquisite ideas, but in some ways he seems particularly unfamiliar.
Naturally, such rawness does not come from Dawn itself, who is regarded as a criminal genius.
