I Have A Super USB Drive

For Chen Chen, who is accustomed to seeing international metropolises, Windhoek is like a remote country, full of two or three-storey small buildings. Only a few hundred meters away can there be a few high-rise buildings that can meet international standards.

The reflection comes from the top of the tallest commercial building.

At this moment, the reflection kept flickering, like a cold star in the day.

Chen Chen still remembers that when he was in junior high school, the teacher once made a metaphor: If you stand by the lake and look down at the water under your feet, you will find that the water is transparent and the reflection of the sun above your head is not strong.

But if you look at the lake from a distance, you will find that the water is not transparent, and the reflection will be very strong, so strong that you can’t open your eyes.

This is the Fresnel effect.

The so-called Fresnel effect is the relationship between reflection and the angle of sight. Except for metals, other substances in the world have different degrees of Fresnel effect.

Chen Chen relied on this effect, coupled with his specially designed location and angle, to make the snipers who assassinated him invisible.

[The other party is 15° above my line of sight. If we regard the positions of the two of us as two points of a right-angled triangle, we can conclude that the inner angles of the triangle are 15°, 75° and 90° respectively.

[Suppose the sides corresponding to the three angles are a, b, c, and the distance from the podium to the commercial building is 560m, that is, b=560, then a=560tan15°=560(2-√3)=150, according to Pythagorean The theorem can be obtained c=√(a^2+b^2), that is, c=580.

[In other words, the straight-line distance between me and the other party is 580 meters.

[There is a female wall on the top floor of that building, which means that the opponent is mounting a sniper rifle on the female wall. Therefore, at the moment of shooting, the sniper scope will generate huge recoil and cause the reflection to disappear. Therefore, when the reflection disappears, It was the moment when the other party popped out.

[At this time, the wind direction is northwest, for the sniper, it is full speed wind, the wind is level 3, the wind speed is about 4.5 meters per second, and the large-caliber sniper bullet shooting at a target 580 meters away is converted into a minute angle equation: range/100x wind speed (km) Per hour)/constant 14, the available minute angle is 6.

[At the same time, a qualified sniper will aim at my chest instead of the head, because the position of the chest is larger and the probability of displacement is smaller. After all, with the power of a sniper rifle, the effect of hitting the chest and hitting the head is exactly the same. Yes, according to the minute angle compensation, the position where the opponent is aiming at me is my right chest. After the bullet is fired, it will hit my left chest, which is the heart position, after the bullet is fired. It is enough to move 20cm to the right to avoid the bullet]

[But to be safe, I'd better move 25cm to the right.

[It is known that the bullet speed of a sniper rifle is 800 to 900 m/sec, that is, at the moment when the reflection disappears, I have a dodge time of 0.644 to 0.725 seconds, but I need to add the delay effect of recoil, and the time is shortened to 0.5 second.

[But enough...]

All these calculations seem to be a long process, but actually only four seconds have passed since Chen Chen discovered the reflection to the present.

Four seconds later, Chen Chen sent the other party's location information by tapping the phone.

"Everyone, the future can be said to be the world of nuclear power plants. As a kind of clean energy, nuclear power plants have several times more advantages than thermal power plants. It will not cause any environmental pollution. At the same time, because our company uses the most advanced The third-generation semi-nuclear power plant technology has an accident probability equal to..."

At the moment when Chen Chen passionately said the three words "equivalent", in his afterglow, the white reflection suddenly disappeared!

It's now!

Chen Chen smiled and spread his hands back for a half step, but when he stepped back,

Whoosh——!

Almost at the same time, a piercing scream passed by Chen Chen's left side, and the violent air current tore the clothes directly, pulling out a blood groove on Chen Chen's left arm!

Up to this time, the audience and the audience erupted in exclamation, and several strong men in black suddenly rushed to the podium, shielding Chen Chen from behind.

...

"No problem, just a slight scratch."

Back at the embassy, ​​a Central European doctor treated Chen Chen's wound with iodophor and cotton swabs expressionlessly.

Around Chen Chen, most of the members of the expedition team, including Qian Wenhuan, Zhou Jing, and Wang Liang, as well as Anthony and legal counsel Jennifer who were in charge of business negotiations, were gathered, as well as their staff.

"Will you get an infection?"

Qian Wenhuan looked scared, and said to the doctor, "Doctor, is there anything that needs attention after being shot, such as not eating spicy and too greasy things?"

"Drink more hot water." The doctor gave Qian Wenhuan a blank look, packed his things and left the room with the medical kit.

"I didn't expect the other party to be so frantic."

Wang Liang on the side frowned, "We haven't offended anyone in Namibia, how come it was a flat tire and an assassination."

"Needless to say, get ready to pack things."

Chen Chen rubbed his arms expressionlessly, picked up his coat and walked outside, "Wen Huan, book the nearest plane ticket."

"...Understand!" Qian Wenhuan opened his mouth, as if he wanted to say something, but in the end he agreed.

"Where are we going?" Wang Liang questioned.

"Of course I left Namibia." Zhou Jing gave her colleague a white look and then walked out of the room.

"Wait, Mr. Chen Chen!"

However, before a few people walked out of the embassy, ​​a group of people from the investment department greeted him, not only Lydia, but Shicuyel was among them. In addition, the leader was a gray-haired man. Old man.

"Mr. Chen Chen, please wait a moment!"

Lydia said in a panic, "This is our fault, and we didn't expect the other party to be so frantic to this extent, you..."

"What else is there to say?" Chen Chen walked past several people, "Let's do it."

"Mr. Chen Chen, Ning listened to Wo say..."

Hicuyelle also hurriedly asked to stay, "Chongzhou has a saying: YO friends come voluntarily, although it must be far away...oh no, not according to the moon, I would rather be a guest of Women, Women..."

Chen Chen still did not stop.

No matter how these people stayed, Chen Chen had already walked outside the door.

"Please wait, Mr. Chen Chen."

But at this moment, the headed old man suddenly spoke.

"Mr. Chen Chen, this is Mr. Bajifi Zurama, Minister of the Ministry of Investment and the Ministry of Mines and Energy!" Lydia suddenly reminded him.

Chen Chen just had a meal at his feet, "Minister Zurama, please forgive me for being unreasonable. Do you have anything else to say?"

"I only say one thing."

The old man looked at Chen Chen with a loud voice, "With other conditions unchanged, our Namibian government is willing to make up for your losses today with a three-year tax exemption and five-year tax reduction policy. Is this sufficient?"

Chen Chen turned around and frowned, "This article will not affect your country's original preferential treatment. If so, please forgive me for not being with me."

"No, I guarantee my ministerial position." The old man nodded.

Hearing this, Chen Chen finally raised a smile at the corner of his mouth. He stretched out his hand and shook his hand firmly with the old man in front of him.

"Happy cooperation, Minister Zurama!"
