I Have A Super USB Drive

For Chen Chen, who was accustomed to seeing international metropolises, Windhoek was like a backcountry, filled with two or three-storey buildings. Only a few hundred meters away were there a few high-rise buildings that could meet international standards.

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

At this moment, the reflective light kept flashing, like an icy star in the daytime.

Chen Chen still remembered that in junior high school, the teacher used a metaphor: if you stand by a lake and look down at the lake water under your feet, you will find that the water is transparent and the reflection of the sun above your head is not strong.

However, if you look at the lake surface from a distance, you will find that the lake 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 used this effect, coupled with his specially designed location and angle, to make the sniper who assassinated him invisible.

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

[Assume the sides corresponding to the three angles are a, b, and c respectively, and it is known that the podium is 560m away from the commercial building, that is, b=560, then a=560tan15°=560(2-√3)=150, according to the Pythagorean The theorem can get 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 parapet on the top floor of that building, which means that the other party is placing the sniper rifle on the parapet. Therefore, at the moment of shooting, the sniper mirror will generate a huge recoil and cause the reflection to disappear. Therefore, when the reflection disappears, It is the moment when the opponent pops out of the chamber. 】

[At this time, the wind direction is northwest, which is full-speed wind for snipers. The wind is level 3 and the wind speed is about 4.5 m/s. The large-caliber sniper bullet shoots at a target 580 meters away and converts it into the minute angle equation: range/100x wind speed (km per hour)/constant 14, the minute angle is 6. 】

[At the same time, a qualified sniper will aim at my chest instead of my head, because the position of the chest is larger and the displacement probability is smaller. After all, with the power of the sniper rifle, the effect of hitting the chest and hitting the head is exactly the same Yes, according to the angle compensation number in minutes, at this time, the position of the opponent aiming at me is my right chest. After the bullet is shot, it will hit my left chest, which is the position of the heart, after the wind deviation. Moving to the right by 20cm is enough to avoid the bullet]

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

[It is known that the bullet speed of the sniper rifle is 800 to 900m/s, which means that at the moment when the reflection disappears, I have an evasion time of 0.644 to 0.725 seconds, but the delay effect of the recoil force needs to be added, and the time is shortened to 0.5 second. 】

【But enough... 】

All of these calculations seemed to be a long process, but in reality, only four seconds had passed since Chen Chen discovered that reflective light.

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, the advantages of nuclear power plants are several times that of thermal power plants. They will not produce any environmental pollution. The third-generation semi-nuclear power plant technology, the probability of an accident, is equivalent to…”

Just as Chen Chen passionately said the word "equivalent", in the corner of his vision, the white reflection suddenly disappeared!

【It's now! 】

Chen Chen smiled and spread out his hands and took a half step back, but when he took a step back,

He seemed to stumble under his feet, his body was slightly unbalanced, and he stumbled 25 centimeters to the right.

Whoosh-!

Almost at the same time, an ear-piercing shriek swept across Chen Chen's left side, and the violent airflow directly tore his clothes, pulling a blood trough on Chen Chen's left arm!

Until this moment, the people off the stage and on the stage burst out with exclamations. Several strong men in black slammed onto the podium, shielding Chen Chen from behind to protect him.

...

"No problem, just a little scratch."

Back at the embassy, ​​a doctor from Central Continent treated Chen Chen's wound with iodine and cotton swabs with no expression.

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

"Will it be an infection?"

Qian Wenhuan had a look of fear, and he said to the doctor, "Doctor, is there anything I need to pay attention to after being shot, such as not eating spicy and too greasy things?"

"Just drink more hot water." The doctor gave Qian Wenhuan a blank look, packed up his things and left the room with the medical box.

"I really didn't expect that the other party would be so maddened."

Wang Liang on the side also frowned, "We have never offended anyone in Namibia, why is it a tire blowout and an assassination."

"Don't say more, get ready to pack up."

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

"...Understood!" Qian Wenhuan opened his mouth and seemed to want to say something, but he finally agreed.

"Where are we going?" Wang Liang wondered.

"Of course I've left Namibia." Zhou Jing gave her colleague a blank look and followed 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 immediately greeted them, not only Lydia, Shikuyele was also among them, in addition, the leader was a white-haired man. old man.

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

Lydia panicked, "It's our fault, we didn't expect the other party to be so mad, you..."

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

"Mr. Chen Chen, Ning Tingwo said..."

Xikuyele also hurriedly asked to hold back, "There is a saying in Chongzhou: YO friends come willingly, even if they are far away... Oh no, not according to the moon, I would rather be a guest of the women, the women..."

Chen Chen still didn't stop.

No matter how these people were retained, Chen Chen was already walking towards the door.

"Please wait a moment, Mr. Chen Chen."

But at this moment, the leading old man suddenly spoke up.

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

Chen Chen paused for a moment, "Minister Zurama, please forgive me for being unreasonable. Is there anything else you want to say?"

"I only have one thing to say."

The old man looked at Chen Chen with a firm voice, "As long as other conditions remain unchanged, our Namibian government is willing to make up for your losses today with a policy of tax exemption for three years and tax reduction for five years. Is this condition enough?"

Only then did Chen Chen turn around completely and frowned, "This one won't affect your country's original preferential treatment. If that happens, please forgive me for not accompanying you."

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

Hearing this, Chen Chen's mouth finally raised a smile, he stretched out his hand and shook hands with the old man in front of him.

"Good cooperation, Minister Zuramar!"
