Goodbye, Professor Xiang.

Beneath the old cheeks, there was a distorted smile, now gilded with a red and blue light, which was the symbol of an ambulance.

The timing was just right.

The corners of his mouth twitched slightly, but he knew he couldn't laugh yet, at least not under the surveillance.

Xiang Haisheng has a history of serious heart disease, and now he will inevitably be sent to the intensive care unit during the onset of the disease.

It all starts from the beginning......

Just after talking to him for the first time, in fact, Wen Yifan's killing intent towards him could no longer be concealed, it was a kind of disgust for rudeness, and this disgust prompted him to almost subconsciously put "killing Xiang Haisheng" on the agenda.

So after learning that he had a history of heart disease through investigation, an evil plan had already surfaced in his heart, but at that time, it was just a general framework, and further investigation was needed to really implement it in detail.

In the past few days in Yunxiang, he would take Wen Qingyu out for a walk almost every day, remember all the architectural details in the vicinity, and draw the diagrams of various structures.

The latter was used as a guide to Jiang Xiaoyu to kidnap him there, successfully writing the full stop between the imitator and Jiang Xiaoyu, while the former was the key to everything - there was a full stop to Xiang Haisheng.

After learning that he had a history of heart disease, Wen Yifan began to put pressure on his heart, intentionally or unintentionally—this could bring a good breeding ground for the final attack on the heart, so that future plans could be better implemented.

Whether it was the intimidation of the first conversation, the identification of the second conversation, or the subsequent kidnapping and dismemberment, etc., through step by step pressure, step by step, Wen Yifan was sure that his heart was already in an extremely dangerous situation at this moment.

Like a person in a desperate situation on a cliff, with a slight push, gravity will get him everywhere.

And this symbolizes the fuse of destruction, the last straw that broke the camel's back, it has a name, it is called monosodium glutamate.

Monosodium glutamate, chemically known as monosodium α-aminoglutarate. The molar mass is 169.111 g·mol-1, and the IUPAC name is sodium 2-aminopentanedioate, which is a salt formed by sodium ions and glutamate ions.

It still seems difficult to understand this substance, but don't worry, it also has another household name - monosodium glutamate.

It is a basic flavoring agent commonly found on the dining table of thousands of households, and almost everyone cannot do without it for three meals, so that almost no one knows the harm of high intake of monosodium glutamate - heart disorder.

That's the key to choosing it.

However, just the normal intake of monosodium glutamate is not enough to pose any threat to people, which is why Wen Yifan chose here.

Almost everyone knows that Sichuan cuisine is known for its spiciness, and because of this, the intense spiciness temporarily overpowers all other flavors, making it impossible to detect a sudden increase in flavor.

And the dishes ordered by Xiang Haisheng are the dishes that Wen Yifan summed up through careful selection that contain the most monosodium glutamate in this Sichuan restaurant.

And after monosodium glutamate, the ice cola he ordered with him added more pressure to his heart - his body, which was originally hot because of the spicy taste, was exposed to a very cold drink, which was almost a disaster for people with a history of heart disease.

That's right, at that time, the reason why Wen Yifan ordered these dishes was also to give him a psychological hint, although he may not have acted according to this hint, it doesn't matter - after all, this is a probability killing, and there is a probability of ten percent, which is enough.

After so much foreshadowing, the already precarious heart suddenly came into contact with an excess of monosodium glutamate, and the final result was that the heartbeat was suddenly disordered, driving the originally fragile heart, making the long-dormant heart attack again.

Even if he didn't have a heart attack, even if he didn't succeed in stealing his medicine to calm his mind when he was pretending to be an old man, it didn't matter, because for his killer, it wasn't here.

Even if he ingested a large amount of monosodium glutamate, it was not enough to cause him to die of direct heart paralysis, and at most he would fall into a coma, as long as the treatment was timely, there was no danger to his life at all.

Therefore, all this foreshadowing is for one thing - that is, to get him to be taken to the ambulance for treatment smoothly, so that the whole plan is already half the success.

This also means that for his real killer...... in the back.

That killer is — the ambulance.

According to the analysis of the road sections, buildings and traffic flow in this vicinity, Wen Yifan found that there were some blind spots at the intersection near here, and then he referred to the road traffic accident records in Yunxiang within a year, and found that this was a traffic accident-prone road section.

A sneer appeared on the corner of his mouth, and now it seems that the scales of Lady Luck are tilted towards the side of the "Grim Reaper".

This may also confirm his sentence that "when a person has a complete grasp of every detail around him, all uncontrollable factors will develop in the direction of that person's favor".

That's right, in the end, the killer of Xiang Haisheng came from one of the most important factors in the death of modern people - traffic accidents.

After deciding to take advantage of this convenience, Wen Yifan immediately formulated a detailed plan to completely block all his ways of life.

At 12:07 p.m. on October 12, Xiang Haisheng from Harvard University in the United States died in a car accident.

And the truck, which had been precisely timed, came from an alcoholic.

The drunkard just last night, drinking with friends all the drinking carnival until almost dawn, during this period, he went to the toilet a total of eleven times, and drank a total of nearly ten catties of eighte-degree beer, and half a catty of fifty-three degrees of liquor, because his own economic strength is not too high, so he did not prepare hangover medicine, but at two o'clock in the morning after returning home dizzy, directly lay down to sleep, until half past six in the morning, did not get up to start a new day's work.

During the drink, he and his friends have been complaining, mostly about work, and complaining about his boss's oppression of employees.

This doesn't sound real - how could Wen Yifan control everything so closely? He is a man, not a god. In fact, however, when it all comes out completely, everything seems so logical......

The drunkard is usually sloppy, and he has no daughter-in-law until he is in his thirties, which also leads to his boredom with life, which is why Wen Yifan chose him.

This kind of useless gear in the city is the most convenient consumable for Wen Yifan, even if a few die, who cares?

Just yesterday, he was scolded by his immediate boss because of his unfavorable work, which not only made him unable to hold his head up among his colleagues again, but even reduced his salary.

The already severe misanthropy makes him habitually numb himself by getting drunk and escape from many unhappiness in life, which is why he chooses to drink.

And going back in time, the reason why the boss who cut his salary was angry on that day was because he was also very uncomfortable on that day.

I just had a big fight with my wife, and I was still sulking in the office, but I suddenly heard that my driver had dropped something, and the originally suppressed emotions suddenly exploded at that moment, and this is what happened after that.

And once again, the time is turned forward, and everything becomes clear - the wife of the small boss suddenly received a letter on that day, and the content of the letter made her angry: it was a video of her husband having sex with another woman, and what was even more odious was that this letter also had a letter written in the voice of that woman, and the content in her heart was roughly all kinds of cynicism and threats to divorce.

How can she, who has a relatively hot personality, swallow this breath? So he immediately scolded his husband with a face, and then went back to his parents' house without doing anything.

In the Middle Ages, a knight was reprimanded by his lord at a dinner party, and he returned to his manor in a rage and threw a tantrum at the butler who did not greet him in time. The housekeeper was angry, and when he got home, he found a trivial reason and scolded his wife again. The wife was wronged, and she happened to see her son jumping on the bed, so she went up and slapped her son. In the end, the kid was inexplicably slapped in the face, and in a terrible mood, kicked the cat that was rolling around.

This is the kicking cat effect that has been passed on step by step, and everything has finally led to the current situation - a truck driven by a driver who is tired of driving and has consumed a lot of alcohol is approaching this way, and at 12:07, it crashes into the ambulance carrying Xiang Haisheng.

6 min 53 sec...... 6 min 54 sec...... 6 min 55 sec......

"Boom-" There was a loud bang in the distance, and the sky-rushing fire lit up the downtown area, and everyone watched in horror at the sudden disaster, and the fear in their hearts passed silently and quickly along with the billowing smoke.

What the? You ask why Wen Yifan was able to control the collision time so accurately? Even if you can control the time when the truck arrives here, how can you control the time of the ambulance?

Isn't that simple? Back here on October 10, the speed at which an ambulance could arrive had been tested – only then another policeman had died from a probabilistic homicide.

Looking at the sky-high fire in the distance, his pupils dilated sharply, and his distorted smile couldn't help it at this moment, and he didn't need to endure it anymore - because he was already dead!

Even if the two cars didn't collide here, or the ambulance didn't choose this way, then don't be nervous, there are still seven accidents waiting for him on the way to the hospital, and now the ambulance can't drive through those sections, and on the other hand, the seven accidents have disappeared.

The whole city is under control.

Taking graceful and comfortable steps on the asphalt road, Wen Yifan walked into the distance unhurriedly, the golden firelight infinitely elongating his shadow and turning it into the outline of a monster.

Death, walking in the sun.
