For Chen Chen, who is accustomed to seeing international metropolises, Windhoek is like a poor countryside, full of small buildings with two or three stories high, and only a few high-rise buildings that can be connected to the international community can barely be seen a few hundred meters away.

The reflection comes from the top of one of the tallest commercial buildings.

At this time, the reflection kept flickering, like a cold and solemn star in the daytime.

Chen Chen still remembers that when he was in junior high school, his teacher once made an analogy: if you stand by the lake and look down at the lake 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 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, and other substances in the world except metals have different degrees of Fresnel effect.

Chen Chen relied on this effect, coupled with his specially designed location and angle, so that the sniper who assassinated him had nothing to hide.

[The other party's position is 15° above my line of sight, if we look at the position of the two of us as two points of a right triangle, we can get that the inner angles of the triangle are 15°, 75°, and 90° respectively.] 】

[Let the sides corresponding to the three angles be 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, and according to the Pythagorean theorem, 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 other party is holding a sniper rifle on the female wall, so at the moment of shooting, the sniper scope will produce a huge recoil force that causes the reflection to disappear, so when the reflection disappears, it is the moment when the opponent is shot out of the chamber. 】

[At this time, the wind direction is northwest, and for snipers it is a full-speed wind, the wind force is level 3, the wind speed is about 4.5 m/s, and the large-caliber sniper bullet shoots at a target 580 meters away into a minute angle equation: range/100x wind speed (kilometers per hour)/constant 14, and 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, the probability of displacement 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, according to the number of minutes of angle compensation, at this time the opponent aims at my right chest, after the bullet is fired, after the wind deviation, it will hit my left chest, which is the heart position, and a 20cm right move is enough to dodge the bullet]

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

[The sniper rifle is known to have a bullet velocity of 800 to 900 m/s, which means that I have 0.644 to 0.725 seconds of dodge time at the moment when the reflection disappears, but with the addition of the delay effect of recoil, the time is reduced to 0.5 seconds.] 】

[But that's enough......]

All this calculation process seems to be a long time, but in fact, only four seconds have passed since Chen Chen found that reflection.

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

"Ladies and gentlemen, the future can be said to be the world of nuclear power plants, as a clean energy, the advantages of nuclear power plants are several times more than thermal power stations, it will not produce any environmental pollution, and at the same time, because our company uses the world's most advanced third-generation semi-nuclear power plant technology, the probability of accidents is equivalent to ......"

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

[Now is it!] 】

Chen Chen smiled and spread out his hands and took half a step back, but when he took a step back, he seemed to have stumbled under his feet, his body was slightly unbalanced, and he stumbled 25 centimeters to the right.

Whoosh——!

Almost at the same time, a piercing scream swept across Chen Chen's left side, and the violent air flow directly tore through his clothes, pulling out a blood groove on Chen Chen's left arm!

It was only at this time that everyone in the audience and on the stage burst into an exclamation, and several strong men in black suddenly rushed onto the podium, blocking Chen Chen behind him and protecting him heavily.

……

"No problem, just a slight bruise."

Back at the embassy, a doctor from Central York was expressionlessly treating Chen Chen's wounds with iodophor and cotton swabs.

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

"Will it be inflamed and infected?"

Qian Wenhuan looked scared, 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 plenty of hot water." The doctor gave Qian Wenhuan a blank look, packed up his things and left the room with the medical kit.

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

Wang Liang on the side also frowned, "We haven't offended anyone in Namibia, why is it a flat tire and an assassination." ”

"Needless to say, let's pack our things."

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

“…… Got it! Qian Wenhuan opened his mouth, as if he wanted to say something, but finally agreed.

"Where are we going?" Wang Liang wondered.

"Leaving Namibia, of course." Zhou Jing glanced at his colleague and walked out of the room.

"Wait, Mr. Chen Chen!"

However, before a few people could walk out of the embassy, a group of people from the investment department suddenly greeted them, not only Lydia, but also Shikuyel, and in addition, the leader was a gray-haired old man.

"Mr. Chen Chen, please wait a little longer!"

Lydia panicked, "This matter is our fault, and 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, I'd rather listen to what Wo said......"

Shikuyele also hurriedly opened his mouth to stay, "There is a saying in Chongzhou: YO friends come voluntarily, although they are far away, they will ...... Oh no, no, it's not according to the moon, I'd rather be a guest of the Wo, the Wo ......"

Chen Chen still didn't stop.

No matter how these people were kept, Chen Chen had already walked towards the door.

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

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

"Mr. Chen Chen, this is Mr. Bajifi Zurama, Minister of Investment and Minerals and Energy!" Lydia on the side suddenly reminded.

Chen Chen paused at this time, "Minister Zulama, please forgive me for being unreasonable, is there anything else you want to say?" ”

"I'll just say one thing."

The old man looked at Chen Chen fixedly, and his voice was loud, "Under the condition that other conditions remain unchanged, our Namibian government is willing to make up for your losses today with the policy of tax exemption for three years and tax reduction for five years, is this condition enough?" ”

Chen Chen turned around completely at this time, frowned, and said, "This article will not affect your country's original discount." If that's the case, please forgive me for not accompanying me. ”

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

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

"Happy cooperation, Minister Zurama!"
