A hidden mechanism.
Of course, this does not mean how high-tech and sophisticated the equipment is, such as a small invisible robot that walks automatically and can poison and kill people without anyone noticing, or something that can deceive the false projection of a surveillance camera. The so-called mechanism here refers to something hidden in the simplest place that can cause specific results due to changes in external factors.
Perhaps it's hidden in the simplest details.
Of course, there are no clues. The water glass with the most poison has now been thoroughly inspected, and the composition and dosage of the poison that caused the crisis have been identified.
According to Jiang Qiu blurting out the data as soon as he saw it, and Mo Yunwan calculating the same answer on the scratch paper for a few minutes, it can be inferred that the concentration of the drink remaining in the cup at that time would be enough to make a seventy-year-old The dose of potassium cyanide required to kill a kilogram adult male would require drinking at least half a bottle - and this is only a conservative estimate.
The liquid collected outside was also tested, and the concentration was even lower than that in the bottle. But the valid conclusion is also here - the fact that the concentration is lower than in the bottle is quite suspicious.
"Generally speaking, if there is a person and a drink in a water glass, if the liquid accidentally leaks out of the bottle mouth, it will indeed fall to the ground along the wall of the glass. But that's where the problem lies." Liang An put his hands on the table while waiting for the result. While explaining, "Even considering that some liquids will be lost in the air due to the evaporation of water at room temperature, the concentration of poisons in the liquid should be relatively reduced rather than increased."
After all, Song Qiaoyu was a serious person who was admitted to the military academy. It wasn't that he didn't understand the common sense of junior high school physics, which meant that he would have doubts if he had to take the next step by himself, so he asked: "What next?"
"Think about it carefully." Shao Zi picked up the worry about the teacher having no successor, and turned to ask Liang An for his opinion, "How about you come over later, sort out all the clues, and then I will ask you? Junior brother, you can do it."
He had doubted for a day or two whether his teacher's genes had been passed down, but he did not give up his last glimmer of hope.
After all, it was a legend. The descendant of a legend had better be a legend, otherwise Shao Zi is afraid that no matter whether he can die happily or not, he will be embarrassed to explain to others after his death - such an old son is placed in the team under his jurisdiction, but he has not learned anything about criminal investigation. skills.
However, the remaining one named Song felt that he couldn't do it.
It's not that he has any intellectual defects, it's just that Song Qiaoyu has always felt that he is not very talented in such brain-intensive things. It is better to focus on other aspects and let his more talented companions take charge of the overall situation while he is responsible. Follow orders.
Save time and improve efficiency. Song Qiaoyu considered himself to be a competent fighter, but at the same time he recognized the fact that he was not very talented in this area.
This is also a habit he has developed.
"As a teacher, you have to find the right student. Don't embarrass him." Mo Yunwan was even more bold.
I guess Lu Yao learned it from her. But Lu Yao is more stubborn. He can do tricks but has no escape skills. He can only rely on his thick skin and young age to get through.
But this time it was a bad start. Someone just wanted to take advantage of the chaos and touch the tiger's tail, but Song Qiaoyu bypassed him with just one word.
"Don't let me waste my time, Captain Liang, you can continue."
The heavy word "you" instantly broke the warm atmosphere created by Shao Zi's teachings.
Mo Yunwan was drunk, and for a moment he thought about what symptoms this Song surnamed person was having today, and whether he should find a familiar living person, a doctor other than a forensic doctor - such as the one who was not at the scene today, even if it was open to the public. The major I attended was not the right one, but at least I could use my extensive knowledge to help me see if there were any new incidents.
Liang An suppressed a smile and nodded.
"If the liquid that flows out of the cup to the ground is not the liquid that oozes from inside the cup, then the same should be true on the cup wall. In other words, if the concentration of the liquid outside the cup is to be lower than that inside the cup, Yao Shenghai needs to go Once in the bathroom, let the cup come into contact with the water a second time.”
This also corresponds to the strange figure suspected of being Yao Shenghai himself after the start of the second half.
It was Yao Shenghai who took the water cup himself and headed to the direction of the bathroom. So what was the purpose of his move?
As he was talking, Liu Che took the water glass as evidence as instructed.
"If my guess is not wrong, maybe the problem lies here."
What made Yao Shenghai come to the bathroom again after halftime, still carrying the transparent water glass. Did he drink the entire drink within a certain period of time? This is naturally impossible.
After all, Yao Shenghai is an extremely particular person. Drinking more than half a cup in one gulp is definitely not what a person like him is used to doing. There is no need or habit for him.
There are only three things that exist near the bathroom and have practical significance to people as viewers. Convenient appliances, sink, and water boiler for heating water.
The three needs are excretion, cleansing, and drinking water.
Assuming that reporter Yao Da suffered from frequent urination, he probably would not have brought a water bottle with him; if it was to replenish water, there is also the above evidence to indicate that this fastidious person is unlikely to drink a whole glass of drink in a short period of time.
Then only the second type remains.
"The water glass slot in this theater is very special. It is tilted at 45 degrees. In other words, a situation will occur when the cup is filled with drinks." Liang An squinted at the lid of the water cup and picked it up with gloved hands to examine it. , “The entire sealing strip area of the cup will also be immersed in the liquid.”
All the tested ingredients in the water glass were left at the bottom, and the distribution of poisons in it was almost all clear. Because of this, the cup is now ready for casual use.
Liang An added water to it. Most of it was filled with random tap water, and some freshly boiled water was added. The temperature of the mixed water warmed the cup, and the detected temperature should be around 40 to 50 degrees, which is just the right temperature for warmth. Finally, put the water glass against the edge of a clean table and place it there at an angle.
Then came up with another clue.
"In the surveillance video taken by the company, reporter Yao's living habits can be seen at a glance. It is consistent with what his apprentice Li You said. He is very afraid of getting hot and does not drink cold water, so he often puts the thermos cup on On the table, open the lid of the cup and let it dry to a certain extent. He is indeed a person who cares about details in life." Liang An dragged the play bar of the video and stopped it at one place, "But there are exceptions. Yao Shenghai himself Life cares about details, but the effervescent tablets his wife asked him to consume were a bit low-key. He had no choice but to carry them with him, but at the same time there would be some small resistance."
The time of surveillance video is adjusted to noon. Even the usually noisy magazine office will have a lunch break. Although this kind of overtime work atmosphere will not let everyone fall asleep during the break, some people still put down the folding bed in the open space of the office to take a nap. Yes, accordingly, other people will also lower their voices to try not to disturb those who are resting during the break.
At this time, Yao Shenghai in the center of the screen also moved. He was originally reviewing the manuscript on the screen, occasionally moving the mouse with his fingers to add marks to the typed words. Suddenly, he glanced at the cup next to him, weighed it to confirm, and finally chose to pick it up, stood up, and left the range of the camera.
Because it was a gray opaque thermos cup that he usually used, I didn’t know if there was any liquid in it.
"He's going to fill up the water?"
The video was quickly skipped during the insignificant waiting time, and then what was seen was Yao Shenghai's return figure.
I still have the thermos cup in my hand.
"Guess why he brought a thermos cup instead of a ceramic water cup that he could put on his desk and have access to at any time?" Liang An turned around and asked.
Before Shao Zi could answer, Mo Yunwan took the lead: "This question has no value at all. Yao Shenghai is a reporter. He may go out to find work at any time because of breaking news. Of course, the drink he prepared at the last moment must be able to be carried with him. It will be a waste. When a reporter has to be pretentious, he cannot go out without bringing anything, otherwise he will be lucky to die of thirst outside."
Normally, Mo Yunwan's nonsense would have been reduced by half. So those are some of the downsides of collaboration.
Liang An nodded.
"Then he made other moves, keep looking down."
In the video, Yao Shenghai took something out of his bag, picked it up, and immediately stood up and walked away, still taking the thermos cup with him.
Obviously, what he took out was the evil effervescent tablet. And just now, he walked aside to blend it with the drink within a certain period of time and brew it into a drink.
The "gift of love" that Yao Shenghai had no choice but to consume.
"Actually, this kind of behavior is not difficult to predict, because during the lunch break, everyone lowers their voices and does not want to disturb others. Obviously Yao Shenghai is no exception." Liang An adjusted the playback bar to the time when Yao Shenghai returned, at two minutes From now on, "the dissolution of effervescent tablets is different from crystals or powders such as normal instant coffee. Its dissolution is similar to a process of slowly spreading in water, accompanied by a harsh sound. Especially when you are closer, you can hear it more clearly." Of course, Yao Shenghai didn’t want others to know about him, and he was also afraid of affecting others’ rest, so he stepped aside and let the drinks be made. In fact, there are similarities in this kind of environment.”
The theater, the stage, the people who are still interested in the performance.
In between the singing and singing, there will actually be silence in the audience. Even during breaks, the audience was not noisy. Perhaps due to the influence of the elegant atmosphere, everyone lowered their voices to prevent themselves from appearing out of place. Even if you attend this kind of performance to be fashionable or pretend to be elegant, you will intentionally or unintentionally make yourself appear more low-key, and your behavior will remain dignified at least for the moment.
Every noise is like the magic of a loudspeaker, and every bit of noise is particularly noticeable.
Like effervescent tablets that squeak on the surface of the water. Even if it is not loud in itself, it will give people the hint of high impact due to the spotlight effect. Because of this, Yao Shenghai will leave according to his habit in the office.
"And Yao Shenghai has a mission. Preparing himself a good drink is not his main purpose. He is very anxious and wants to get his own 'exclusive revelations'." Liang An said with a smile, "Of course, there is no doubt about this aspect for the time being. After all, except for the camera, we don’t have any evidence to prove the existence of this revelation. But since the camera exists, we may be able to use this handle to get the apprentice he deceived from the awakened Yao Shenghai, and come here to investigate secretly The reason. When it involves his own life, I don’t think he will hide it.”
"so what?"
Liang An took a deep breath: "So, he needs to catch up with the time and not let himself miss this opportunity. Since he has spent so much time to come, he will not let himself waste time for such a trivial matter. After finishing, he I immediately returned to my seat with my own water glass.”
At this moment, Liang An pointed to the water cup body with the lid tightened and put aside.
Now there are some changes on it.
Water is leaking out of the cup cover drop by drop, and slowly sliding down the transparent cup body, very slowly, but at an even speed.
The inclination of forty-five degrees is just enough to allow the "escape" of this liquid to be neither fast nor slow, but it always exists.
It’s not easy to notice – but it always adds up.
