It's too late, it's too soon!

I saw that the fireball flew through the window in an instant, flew straight into Chen Fei's classroom, and completely lit up the whole room at once!

At this time, the children were completely frightened by the dazzling fireball, and they screamed while lying on the table with their heads in their hands, and some of the children had even gotten under the table!

Chen Fei has been bold since he was a child, and although he also felt scared and frightened at this time, he still tilted his head and squinted at the fireball. Pen % fun % Pavilion www.biquge.info

The fireball was slightly larger than a basketball, and it was orange-yellow, but it glowed with dazzling white light, and it looked like a shrunken sun! Looking directly at the past, it made people feel dazzling and hot, as if it could melt everything in an instant......

......

The fireball always kept a distance of about two meters from the classroom floor, and it was erratic, and it seemed to be consciously wandering around the classroom, and then flew straight to the front of the classroom, and flew straight to the side of the podium before stopping.

However, it only stayed next to the lectern for a few seconds before it suddenly sped up and rushed towards the classroom door!

At this time, the Chinese teacher was standing at the door of the classroom in a daze, and she didn't have time to react, let alone dodge......

......

At that time, Chen Fei saw with his own eyes that the fireball swooped down from mid-air, and hit the Chinese teacher's chest directly, and then emitted a flash of lightning like lightning, and at the same time made a loud thunderous sound......

......

I don't know how long it took, the rain finally became lighter, and the sky gradually brightened, but at this time, the children had not yet recovered from the terrifying scene just now.

Although they still couldn't believe and couldn't understand what had just happened, they raised their heads and opened their eyes, looking around in horror. But I saw that the Chinese teacher was gone, and at the door of the classroom, there was an extra charred corpse......

......

Later, a number of relevant departments participated in the investigation of the matter, and soon the results of the investigation were available, and the conclusion was that this was a rare lightning incident!

And that sun-like fireball is what they call it ball lightning!

Ball lightning?!

That's right, ball lightning!

Later, Chen Fei saw an introduction to ball lightning in a science and technology magazine - ball lightning, commonly known as rolling mines. Usually occurs during thunderstorms and is a ball of lightning. It is a real physical phenomenon, it is very bright, nearly spherical in shape, and varies from about 15 to 40 centimeters in diameter. It usually lasts only a few seconds, but there are records of it lasting for 1 to 2 minutes. In addition to the common orange and red, there are also yellow, purple, blue, bright white, and dark green auras, and they come in a variety of colors.

Ball lightning is more harmful, it can fly freely in near-Earth air with the ups and downs of the air current, or go against the wind. It can enter the building through open doors and windows, and it is common to enter the building after passing through the chimney. It can even slide on wires, sometimes hovering, sometimes disappearing silently, and sometimes exploding when it hits an obstacle.

Ball lightning is mysterious because it is uncommon, unpredictable, varied in color and shape, and has enormous instantaneous destructive power. Therefore, as early as ancient Greece, people began to pay attention to this strange natural phenomenon.

But then it was pointed out that ball lightning is not lightning and that it has little in common with lightning. Natural lightning is also called thunder and lightning. The most common form of lightning is a line of lightning, which resembles a vertical and horizontal branch overhanging in the air, or a river with many tributaries on a map. The ball lightning is also called the electric light fireball, but it is not lightning, it has almost nothing in common with lightning, so it is inaccurate to name this phenomenon "ball lightning", and the ball lightning should be named "electric light fireball", that is, the plasma luminous ball related to the electromagnetic field. But most people still call it ball lightning......

......

Oh, I see, that weird fireball is the legendary ball lightning, and I can't wait to see how terrifying it looks, so incredible.

And that Chinese teacher is really, this rare wonder of the world for thousands of years, but she just ran into it, and somehow became the only victim in that incident! In this way, I don't know whether to say that she was unlucky or that she was lucky, but she was turned into charcoal at that time, but she still reached for the doorknob, maybe she wanted to escape from the classroom at that time.

Of course, the biggest victim of this incident is the Chinese teacher, because she died heroically because of this incident after all. But the poor children were also victims of this incident, because it was deeply engraved on their young hearts, and I wonder if it hurt them or not. But just from the fact that Chen Fei would still involuntarily and inexplicably walk into this classroom more than 20 years later, presumably the ball lightning incident back then had at least stimulated him......

......

It stands to reason that this should be the end of the matter, because no one wants to recall the horror of that time. But later, the outcome of this incident still changed a little.

According to the children who were present at the time, after the fireball rushed into the classroom that day, many people heard the fireball make a strange sound. And the voice was like the cry of a little girl.

Well, that's a bit weird, how can that ball lightning still make a sound like a little girl's cry? It sounds pretty fresh.

Naturally, the experts would not take the children's unreliable testimony, but the children were sure that they had heard the girl's cry at that time. So the experts explained that it was probably because the children were overly frightened and delusional, or it could be a similar sound made by the ball lightning itself, and most likely because there were girls in the classroom who were scared into crying by the fireball......

......

Although the experts gave several explanations for the inexplicable girl's crying were all reasonable, the stubborn children at that time did not agree with it. They still firmly believe that the ball lightning at that time was the cry of a girl, and it was not an illusion or a similar sound, and there could be no mistake!

Because, according to the children present, the cry was clear and obvious, as if someone was sobbing softly in their own ear, so it was not an illusion. Moreover, it is impossible for so many people to have a delusion together, there is no such coincidence in the world...... (To be continued.) )
