Genius is just the threshold for me!

"Let me see!"

Su Yue was the first to squeeze through, her eyes widening as she took a look. Her expression froze for a moment, then she said speechlessly, "Isn't this just a striped sunset cloud? It's just that the shape is a little different."

"That's not the sunset. Look at the very front of this beam of light and shadow. Isn't there a different kind of shadow? That's the aircraft!"

Li Tao's eyes widened, and he zoomed in on the image, pointing to a blurry black figure in front of him: "Look, isn't that it?"

"This... is a flying machine?" Huang Qingyao leaned closer to take a look, her expression also momentarily stunned.

"Li Tao, don't believe everything you read."

Zhang Yihao glanced at it and couldn't help but give Li Tao the middle finger, saying, "This shadow looks like a mosaic. I would believe you if you said it was because his lens wasn't clean or because of atmospheric dust, but an aircraft?"

"I also saw the video; look at the footage, and the final sound!"

Li Tao refused to give up. He exited the forum, opened his photo album, found a saved video, and clicked play.

A faint bright spot streaked across the sky, followed by a small, jellyfish-like band of light, its colors somewhat dazzling.

However, due to its small size, it blends into the background of the surrounding sunset and is completely inconspicuous.

The band of light lasted for several tens of seconds, and at the end of the video, a very faint, low hum could be heard from the sky.

"A forum expert has already determined that the speed of this light spot is at least Mach 8 and its altitude is over 4 meters. The jellyfish-like light band is the exhaust of an aircraft, the light and shadow band left by the setting sun, and the final low hum is the sonic boom in the sky..."

Li Tao said confidently, "This video is proof enough, isn't it?"

"this……"

Su Yue read it carefully, thought for two seconds, and said, "If you hadn't mentioned it, I wouldn't have noticed. This sunset is indeed different; it's quite beautiful."

"This... is indeed a sunset."

Jiang Caiping whispered from the side, "It doesn't look like the flight path of an aircraft."

"This isn't a sunset!"

Li Tao widened his eyes and retorted.

"Yes, it's not a sunset glow; it's a normal natural atmospheric phenomenon."

Zhang Yihao then found the relevant information and photos, and took out his phone to explain: "These phenomena were noticed by people last year."

Many military enthusiasts went to ask the General Zhang, who had already explained that it was a peculiar atmospheric phenomenon.

Take another look at this video posted by a netizen in 04. The lighting, the light streaks—aren't they very similar to yours? Mine is even bigger… You can't exactly say that we built a hypersonic aircraft in 04, can you?

"Hmm, the photo Hao found is better than Tao's," Lin Dong said, glancing at the photo and nodding as he ate sunflower seeds.

"This should be a natural atmospheric light and shadow phenomenon, such as anti-twilight or noctilucent clouds."

At this time.

Xia Ran gave Lin Dong a new bag of sunflower seeds, and then gave the others their favorite fruits and snacks. After looking at the photos and videos on Li Tao and Zhang Yihao's phones, she explained softly, "The true sun is blocked by the horizon and mountains."

However, dust, turbulence, and ice crystals in the upper atmosphere can still be exposed to sunlight due to their altitude. After the sunlight scattering effect, various colors and shapes of light and shadow can be seen on the ground, which can usually be seen at sunrise in the morning and sunset in the evening.

However, most of the light and shadow effects are quite ordinary, not much different from a normal sunset.

But sometimes the scattered light and shadow can be quite unique, with various shapes and changes, making it look very strange.

It's like the clouds in the sky; they come in all sorts of shapes, and sometimes their shapes are incredibly lifelike.

Is that really the case?

Li Tao's eyes widened, and he said with a face full of disappointment, "Is it really a natural atmospheric phenomenon?"

"Do you think we'd lie to you?"

Zhang Yihao scoffed from the side, "Think about it, if there really is a hypersonic aircraft, only Chengdu Aircraft Industry Group and Shenyang Aircraft Corporation in China have the capability to conduct research on it."

Shenyang Aircraft Corporation's core team took a collective leave of absence last year, and Chengdu Aircraft Corporation just completed the development of the J-20 a few years ago and is still working on other projects. None of us can just go out casually... Where would we find the time to research hypersonic aircraft? We can't just pop out of thin air.

"Yes, Brother Hao is right."

Lin Dong sat on the side, cracking sunflower seeds and acting as the straight man.

The most common flight trails of aircraft are condensation clouds, which are formed when the humidity at low altitudes suddenly increases and the aircraft's exhaust causes water vapor in the air to condense.

Besides condensation clouds, there is another special type of flight path: the twilight effect.

When a spacecraft reaches the critical airspace of the atmosphere or even outer space beyond the Kármán line, and the time is exactly thirty minutes before sunrise or after sunset, the sunlight at high altitude will scatter on the condensed exhaust gas of the spacecraft, creating a magnificent light and shadow effect.

At the same time, because the air pressure above the critical airspace is extremely weak or even zero, the exhaust gas from the aircraft will exhibit a diffusion effect, eventually forming a magnificent cloud resembling a jellyfish. This is the critical airspace aircraft, as well as the twilight effect commonly seen in space rocket launches.

As for the Hottest test flight, which evaded satellites in the sky but was photographed on the ground or observed by telescopes by chance, Lin Dong was not too surprised.

After all, there are over a billion people in our country, and countless people use binoculars and cameras to observe and photograph various sunset scenes every day. It's not surprising that someone might happen to capture one.

Of course, even if he were photographed, Lin Dong wasn't worried about it being exposed.

One reason is that Hot Hot is too fast; unless you have a professional ultra-high-speed camera, you simply can't capture its appearance.

As for the twilight effect left by flying in the critical airspace...

Ok.

It can only be said that atmospheric phenomena are indeed a category that can be categorized into all sorts of strange and unusual phenomena.

Among the various strange atmospheric phenomena, many can be correlated with the twilight effect; the examples Xia Ran just gave are only a part of them.

This is also why, despite the large number of J-1 fighters in service, they have never been exposed due to flight traces.

After all, compared to the twilight effect caused by space rockets, which can span the entire sky and cover half the sky like jellyfish rocket clouds, the twilight effect created by Hot Air is really too small.

The former is so spectacular, like a sword opening the gates of heaven, that it cannot be contained within the framework of normal atmospheric phenomena.

However, the latter is so small that it is difficult to observe with the naked eye. Even if it is captured by a telephoto camera, it is not spectacular enough and is hardly noticeable in the evening sky with its various sunsets and twilight.

After chatting for a while, it was past 12:10 noon.

As soon as the kitchen door opened, a rich aroma wafted out.

He Ying, wearing an apron and carrying a large pot, came out and called out to Xia Ran, "Ranran, call everyone to eat!"

"Wow, dinner's ready!"

Su Yue was the first to jump up from the sofa and run towards He Ying: "Aunt He, chicken stew with mushrooms, I'm here!"

"Yueyue needs to wash her hands!"

He Ying placed a pot of chicken stew with mushrooms on the dining table, reached out to block Su Yue, and pointed to the handwashing area with a smile.

"I know, Aunt He, I just smelled it first to see where the chicken leg meat was."

Su Yue grabbed He Ying's hand and answered cheerfully, taking a deep breath to savor the fragrance before running off to wash her hands first.

soon.

After everyone lined up to wash their hands, He Ying brought out all the dishes.

Braised pork with vermicelli, braised chicken with mushrooms, sweet and sour pork, stir-fried eggplant, potatoes, and green peppers, stir-fried pork slices with wood ear mushrooms, and dried tofu with green peppers—all dishes from different cuisines than those in Sichuan. Although there were only six dishes for eight people, each dish was very generous in portion size.

Everyone found a seat, and before Su Yue, the foodie, could even start eating, Xia Ran picked up a large spoon and scooped a spoonful of chicken and hazel mushrooms soaked in broth for everyone, explaining with a smile.

"The hazel mushrooms this time were all wild, small, unopened hazel mushrooms picked by my grandfather in the mountains back home. The vermicelli was also sent from my hometown. The taste is even better than last time..."

Ok?

Su Yue was stunned to see that Xia Ran had taken away the best and largest piece of chicken leg meat that she had spotted first, in the short time she had just picked up her chopsticks.

She glanced at it, and upon closer inspection, immediately realized that it had already been placed in Lin Dong's bowl.

At this moment, Huang Qingyao noticed Su Yue's subconscious reaction of looking for chicken drumsticks. After looking at her for a moment, she seemed to have discovered something, picked up her chopsticks, grabbed the chicken wings from her bowl, and put them into Su Yue's bowl.

"My class monitor, the class president is giving you a chicken wing as a reward. You'd better work hard next week."

"Of course, of course!"

Seeing that the chicken thigh meat he had been eyeing had been taken away, he was given an extra piece of chicken wing that he also liked.

Su Yue's face lit up with a smile. She picked up a chicken wing, took a bite, and exclaimed in amazement, "Wow... Aunt He, this chicken stew with mushrooms is really different! The flavor is so much richer and more delicious!"

"Really?"

He Ying, sitting to the side, noticed the little incident of serving the food earlier. Hearing Su Yue's words, she couldn't help but smile and say, "If you like it, eat more. Come here often in the future."

"Definitely! I'll stay at your place, Aunt He!" Su Yue replied with an exaggerated expression.

"Then Auntie will tidy up the room in a bit."

He Ying smiled happily, but after smiling for a moment, she saw Lin Dong sitting next to Li Tao, who was looking down and sharing the taste of hazel mushrooms with Xu Qingling on the other side.

She glanced again at her daughter, who was quietly eating after serving the dishes, her expression revealing nothing amiss, and couldn't help but sigh inwardly, "What a tragedy!"
