Women only affect the speed of my reasoning!

She deliberately and cautiously glanced back: "Is it about when you will come to propose marriage to our little Yukino?"

"Yes, you guessed it."

"Well...I don't believe it."

"Then you know it's impossible and you still say that on purpose?"

Qin Sanshu gave him a caring look.

Yang Nai pursed his lips slightly: "I'm just joking to tease you."

"I laughed……"

The two walked out of the WSG Association building almost side by side. Not far from the downstairs gate, on the roadside in the sunshine, more than [-] buses, linked end to end, were waiting quietly.

Yang Nai followed the large army to the left, while Qin Xianshu went to the right.

"Huh? Where are you going, Xianshu? Our bus is over there~"

However, what responded to Miss Yukinoshita was the high school detective's back walking away gracefully, and his hands waving casually.

"You guys go ahead, I'm not traveling with you. I'll see you at the hospital later."

After saying these words, Qin Xianshu strode away.

Ten minutes later, a low and surging engine sound echoed in the indoor parking lot near the Nagoya WSG Association building.

Astride the Fenrir, Qin Sanshu put on his helmet and gloves with a sense of safety, turned on the on-board positioning system to locate the path point to the hospital next to Nagoya International Airport, then put on gear and set off.

This is indeed a big gamble, and the bet lies in whether the murderer's ultimate target is John Floyd.

In this bet, Qin Sanshu Stud had the upper hand.

He believes that if the other party is a copycat of the incident 15 years ago, and the ultimate goal is to kill John Floyd, then the murderer has no reason to execute the first two kidnappings so sloppily, as if he is just coping.

It's not even a kidnapping. It's just a matter of knocking people out and throwing them in a corner. From the beginning to the end, except for the kidnapping of a specific person, the rest didn't show any objection to WSG being held.

Under these many doubts, as long as the prisoner is not just a person who just wants to have fun, then the ultimate goal will be obvious.

——The prisoner just wanted to tell someone through this series of perfunctory crimes that the case 15 years ago was about to happen again.

As for who this person is, it is naturally Alan Mackenzie, the president of the WSG Association and a senior executive of the FBI, who will arrive at Nagoya International Airport at 10:30 this morning.

Of course, some people may say that the prisoner's target may also be John Floyd.

Yes, there is a possibility, but the possibility is not high. It is only about [-]-[-], or even only [-]-[-].

And if the ultimate target is Alan Mackenzie, as Qin Xianshu guessed, then the identity of this prisoner is basically ready to be revealed, but it is a pity that it was blocked by the bullshit witness protection plan.

Therefore, the current inference is that the prisoner will basically attack John Floyd. This is almost a certainty, but the probability of killing him is extremely small, and he should not choose to attack at the airport.

Maybe it was during a physical examination in the hospital, or maybe it was during a lunch break.

But no matter what, Qin Xianshu must allow himself to maintain sufficient mobility.

"It's really exciting. This kind of tension of not knowing where the enemy will attack from..."

So a group of buses set off from the WSG Association building to the airport, and Qin Sanshu went straight to the hospital where they were about to have a test drive physical examination, and found a parking spot closest to the exit to drive Fenli to the airport. Stop it.

It is said to be next to the airport, but it is really next to the airport. The hospital is located less than 50 meters away from the Nagoya Airport terminal, and is connected by a communication bridge in the middle.

The two parties set off one after another, but arrived almost at the same time.

Qin Sanshu had just parked his motorcycle in the parking lot and entered the hospital. As soon as he went upstairs, he saw a huge army walking across the communication bridge under the guidance of Baijiu Maiko.

The leader was none other than Alan Mackenzie, followed by Representative Yukinoshita, John Fold and others, as well as other sponsors and test passengers.

Seeing Qin Xianshu suddenly appear in front, Baijiu Wuzi, who was leading the way, was stunned.

She recognized him. After all, he was sitting in the first row of the audience when she was giving an explanation on the stage. His posture was extremely leisurely, which impressed her deeply.

"Sir, you..."

"I just felt a little uncomfortable in my stomach, so I went to the bathroom and came directly. Is there any problem?" Qin Uanshu lied casually.

"No...no, that's not what I meant..."

Baijiu Maiko couldn't tell the truth from the false, and even if she could tell, there was nothing she could do, so she had to choose to remain silent.

The place where the physical examination is concentrated is in a large room, which is estimated to be as long as two Sobu High Multimedia Classrooms connected together. Near the window, a long row of tables and chairs facing each other are neatly arranged, and on each table are placed There is a blood pressure measuring machine and a nurse sister with a sweet smile sitting behind each table.

"Considering that you are about to board the world's first vehicle with a speed of [-] kilometers per hour, although all safety simulations have been passed, please still have your blood pressure measured here. After the examination, you can move around freely..."

After Baijiu Maiko finished speaking, the army immediately took action, and everyone stepped forward one after another to line up to take blood pressure measurements.

President Alan walked first and was also the first to take blood pressure measurements.

He sat down at the table, his posture upright, but when he took off his suit jacket, a small bottle of drink accidentally slipped out and fell to the ground.

"Oops……"

He is worthy of being a senior officer of the FBI. Although he is relatively old, his reaction is still sensitive. When the drink fell out, he said bad and stretched out his hand to try to pick it up.

But someone was a step ahead of him.

"energetic drinks?"

Qin Xianshu caught the bottle in the air, took it in his hand, stood up, took a look and said in English, but the people around him couldn't even see clearly when he made the move.

He stepped forward and handed the drink to Alan Mackenzie.

"Your drink."

"Oh, thank you."

Alan Mackenzie took over and explained with a smile.

"I bought this at the airport before. After all, I haven't slept all day and night. It would be bad if I fell asleep during the opening ceremony."

"It doesn't matter if you just fall asleep..."

Qin Xianshu answered fluently in English, and the second half of his sentence switched back to Chinese.

"As long as you don't defecate openly at the opening ceremony."

"...What?"

"No, nothing."

Chapter 110 A Fatal Mistake

On the second floor of the hospital, the test drive physical examination is still going on in an orderly manner.

Following President Alan, Qin Ushu, John Foid, and Representative Yukinoshita also had physical examinations.

The test results were naturally all normal, except that Yukino's blood pressure was a little low, but it was nothing serious.

In the final analysis, this is more like just going through a process than a serious examination.

After all, the same speed is hundreds of kilometers per hour. There is no reason to say that you can ride on an airplane but not on the subway.

In order to cope with today's "final battle", John Floyd even specially hired two bodyguards to follow him wherever he went. He would even stay by the bathroom when he went to the bathroom. He looked very professional in his straight suit. His gaze is like a searchlight, constantly alerting the surroundings.

But not only why, even indoors where the sunlight is not strong at all, they all still wear sunglasses.

Could it be that it is produced by Painxun and can prevent flash bombs?

Qin Sanshu sat on the public waiting bench with her chin propped up, thinking a little boredly.

Not far away, Xue Mu was still waiting in line for a blood pressure test.

In fact, he was able to move around freely now, but Yangno pulled him and said that he must treat him to Nagoya's famous local eel three times, so he was forced to stay and wait together.

"Mr. Freud is really cautious. With the help of a great detective like you, he actually hired two personal bodyguards."

Seeing Qin Sanshu looking like he was doing nothing, Yang Nai, who was sitting next to him, came over and said deliberately.

"It's normal." Qin Xianshu didn't take it seriously. "After all, it is basically 100% certain that he is the imitator of the case 15 years ago. No matter how perfunctory the first two kidnapping cases were, we would still worry about the prisoner trying to restore the degree of restoration to a high enough level. If I forcefully and perfunctorily destroy him with one shot, you would do the same thing if you were put in the same position."

"Well……"

Yang Na pursed her lips, unable to comment but still wanting to say something else.

At this time, a strange sound suddenly came from above their heads.

rumbling--

It wasn't thunder, but something deeper and more disturbing.

Qin Xianshu was shocked when he heard the sound, and suddenly raised his head upwards, as if he felt something in his heart.

You must know that large hospitals of this kind are basically equipped with central air conditioners. The ventilation ducts in the air outlets extend in all directions and are connected to each other. Not only one of them is so loud, but all the air outlets are emitting such a sound at the same time.

For a moment, almost everyone in the hospital raised their heads and looked toward the ceiling.

The next second, like a flood bursting its banks, countless air outlets fell off with a series of loud bangs.

They didn't fall by themselves, but were blown out by the large amount of gas suddenly rushing out of the air-conditioning ducts, just like opening champagne.

But what spewed out of the air outlet was not champagne, but a large stream of white smoke.

"Damn it, are you playing so big?!"

Qin Xianshu was stunned. In an instant, he felt that all the blood in his body was cold.

Dust, a large amount of dust, when a sufficient amount and density of combustible dust fills the air, it only takes a small flame to explode instantly.

Well, an explosion in a physical sense.

It's like there was a funny joke. The teacher asked students to fill the classroom with something. The first student used newspapers, but he could only cover the ground. The second student used flour, but unfortunately he couldn't completely cover it. It was filled with corpses, so the third student was very resourceful and took out a candle and lit it... and the classroom was filled with corpses.

And now, there's a good chance the hospital will be filled with corpses.

Qin Xianshu reacted very quickly. He jumped up on the bench and kicked him again. His whole body immediately flew towards the window.

Just when he was about to kick out the window, he heard the sound of falling to the ground behind him, and there were more than one sound.

"Ok?"

The high school detective looked back in shock and landed, only to see Yukino falling to the ground covering her mouth and nose next to where he took off, as if he had fallen into a coma.

Wait, why a coma?

Before Qin Sanshu could figure out the problem, Xue's father, who had the instinct to protect his two daughters, also fell to the ground, followed by Yang Nai, and then Xue's mother.

In the chaos, people around him fell one after another. Correspondingly, more and more doubts appeared in Qin Uanshu's mind, but they were basically the same.

Can flour cause coma?

The answer is of course not, it is true that I will choke.

There is a saying - eliminate all impossibilities, and whatever is left will be the truth no matter how unreasonable it is.

So the conclusion is that what is sprayed out of the air outlet is not dust at all, but... helium!

Failure!

This is a piece of trivia that is of little use but is really useful at this time.

The hospital's MRI, that is, magnetic resonance imaging, uses superconducting magnet technology. In order to ensure that it is always at ultra-low temperature, liquid helium is used in the cooling system. However, if the temperature rises due to some reasons, , the liquid helium used for cooling will undergo explosive vaporization, that is, quench.

After a quench occurs, the explosive outflow of helium will rapidly reduce the oxygen concentration in the air, causing suffocation or even death.

Hesitation leads to defeat, and a brief hesitation leads to fatal mistakes.

In less than two seconds when Qin Xian was stunned, an air outlet that happened to be above his head suddenly collapsed, the wind guide blades flew to the side, and white mist poured down like a waterfall, instantly covering his whole body. shrouded in it.

"Damn..."

The high school detective's reaction was quick enough. He had already reacted when the guide blade collapsed. He immediately took a deep breath and tried to hold his breath, but unfortunately he was still a step too slow.

The helium gas came with too much force, and no matter how fast Qin Xianshu moved, he still inevitably inhaled some of it.

In an instant, a strong feeling of dizziness hit my brain, and my limbs felt as heavy as lead.

Qin Xianshu's legs weakened, one knee hit the ground heavily, and then the whole person fell to the side.

Soon, no one in the entire hospital was awake anymore, and only the alarm bell continued to sound.

No, actually there are.

20 seconds after everyone fell into coma, two steps entered the medical examination room one after another. They carefully avoided the "bodies" scattered on the ground, and came to Alan Mackenzie and John Fould respectively, and then one person dragged them up One, left quickly and quietly.

"Uh--"

After a while, a suppressed groan sounded in the medical examination room, and a figure struggled to stand up from the ground on his knees.
