Chapter 178

This is the basic principle of airplane contrails.

"If an airplane has contrails, there must be a condition!" Old Mr. Ding muttered to himself, as if speaking to others (though the others had no idea what he was saying).

"That is, it must be in a low-temperature environment at high altitude!"

The old gentleman's face suddenly turned red.

He became excited.

"Generally, it requires an altitude of around 8,000 meters and a temperature as low as minus 40 degrees Celsius or below for such airplane contrails to form."

"Because essentially, this is carbon dioxide and water vapor from the combustion of hydrocarbon fuel."

"So it must be in a low-temperature environment of at least around 8,000 meters to form!"

"Ah... Wonderful! Wonderful! This young man, he actually analyzed this detail in his mind long ago! Wonderful!" Old Mr. Ding shouted, muttering to himself.

The entire conference hall was filled with only his voice and his pacing back and forth.

"Airplanes below this altitude cannot form contrails!"

"And after exceeding this altitude, the airplane enters the stratosphere, where it no longer needs to heavily engage the engines to release exhaust!"

"And at this moment, in this photo, the airplane in the night sky outside the window has contrails on both sides!"

"This proves! This airplane must have been flying over the location of the image at an altitude of around 8,000 meters in a low-temperature environment!"

"Above 8,000 meters..." The old gentleman closed his eyes to ponder, then suddenly opened them. "Help me check the maximum climb rate of the Boeing 747; how long does it take from takeoff to climb to this altitude!"

Someone nearby received the order, not knowing why this information needed to be checked, but simply started checking anyway.

The result was found quickly.

"The maximum climb rate of the Boeing 747 is 10.2 (m/s). Even if the airplane ascends at this speed continuously, reaching an altitude of 8,000 to 10,000 meters would require at least 1,000 seconds, which is more than sixteen minutes."

"But such a large passenger aircraft cannot maintain the maximum climb rate from takeoff, so the time to reach 10,000 meters would be even longer, generally requiring around half an hour..."

"Right!! Half an hour! Right! So we should look for flights that took off half an hour earlier!"

"The photo shows night, so the takeoff time of this flight must be around night! Hahaha! Quick! Check the information for this flight taking off at night!"

Quickly, the result came out.

"Old Mr. Ding, there is no information on this..."

Old Mr. Ding's eyes widened. "Impossible! How can there be nothing?!"

"But there is information for a 13:05 takeoff."

"13:05??" The old gentleman was greatly shocked.

What, it was 13:05??

Suddenly, the old gentleman froze completely.

He grabbed the paper with the notes on the table.

The number recorded on it earlier:

CNMU9201305!

The last four digits, 1305!!

"This! This!" The old gentleman stepped back several paces. "Where did this number come from?!"

"Earlier, Ning Chen—that is, the streamer Brother Shiguang from the live broadcast room—suddenly wrote this down in the hotel earlier tonight..." someone nearby said.

"What??? He actually wrote down this time point long ago???"

The old gentleman looked as if he had seen a ghost.

The others looked completely confused.

They had no idea what was actually happening right now.

Everyone sensed the old gentleman's abnormal behavior and looked at him simultaneously!

The old gentleman's face turned crimson.

His eyes suddenly widened, as if his eyeballs were about to burst!

His mouth was slightly open, and his lips moved a few times.

Suddenly, the old gentleman closed his eyes.

Then, he opened them again!

The old gentleman's mouth slowly opened.

His head tilted backward.

Liu Ju was startled, thinking Old Mr. Ding was about to faint!

Just as he was about to step forward to support him, he heard a sound,

"Ha—haha—hahahaha..."

The old man laughed heartily, looking up at the sky.

Everyone was left dumbfounded.

Liu Ju had known Old Mr. Ding for over twenty years.

From then until now, the two of them had been friends for more than twenty years.

Old Mr. Ding received a good education and was a refined, gentle old intellectual; he always spoke politely and gently, never even raising his voice.

But today was the first time.

Seeing this old gentleman.

Laugh so openly, even to the point of—being unrestrained!!

After laughing, the old gentleman said directly.

"Awesome! Awesome! Simply a genius! Genius! This kid named Ning Chen! He is damn well a genius!!"

The others.

Seeing the old gentleman's reaction.

Everyone was stunned.

And what exactly happened tonight?

Everyone, simply, didn't understand a thing!

But they understood.

This moment did not belong to anyone else.

It belonged only to Mr. Ding Xiangdong and that young man named Ning Chen.

This was merely a dialogue across the void between the two of them!

And what was even more terrifying was.

In this dialogue.

An existence of Mr. Ding's level actually!

Was left behind by this Ning Chen!

"Mr. Ding, what exactly is..." Liu Ju, with a completely bewildered face, stepped forward and said.

Mr. Ding's face was flushed.

Yet he suddenly raised his hand.

"I don't want to explain to you. Even if I did, you wouldn't understand."

He sighed, "I can only say, the younger generation is formidable. To have such a young man leave an old withered person like me behind by such a vast distance is truly admirable."

Hearing the old gentleman say this, everyone else, especially Yue Feiqun, was even more bewildered...

Daily updates of a hundred books, free book search, irregular new book releases... were bewildered...

"Let's not talk about anything else!" The old gentleman looked at the others.

"Did you see the building he finally located on the map just now?"

Everyone looked at him.

Still confused.

"That building is, at that time, the exact location where Li Sai Gao filmed the video!"

Upon hearing these words.

The entire hall plunged into icy coldness.

Silence fell like a dead crow.

For a long time.

Everyone's eyes widened.

"I know you must be very confused about how he actually did it on the peninsula!"
