A day later, the Himalayas ......

Known as the "home of snow" in Tibetan, it is also the highest place in the world, and for the first time in history, human footprints have been streaked in its rarely visited sky.

Zhang Yun's day-by-day team was divided into two groups, piloted two C-47 transport planes, and entered this ancient and barren world in the mode of flying in formation.

However, the groundbreaking feat did not bring any good mood to the pilots who were currently there.

At least that's what David Brand thinks......

He even had the illusion that he was flying in a huge labyrinth.

He was flanked by high mountains, deep canyons, almost zero visibility in the air, and white snow-capped mountains as far as the eye could see, and the peaks on both sides seemed to be walled by ice blades, sandwiched between the sides of his wings, ready to come into close contact with his C-47.

"What the hell is this!" He couldn't help but curse with hatred, "This must be a world abandoned by God!" ”

This sentence caused Kip next to him to give him a loud thumbs up, and George could be heard moaning.

"These canyons are too narrow. I estimate that the maneuverability of the previous segment may be less than 0.3. ”

"Don't complain. On the bright side: this is a feat that has never been done before in human history, and you will go down in history. Zhang Yun said to George.

He and George were the first group to lead the flight.

"If we still have our lives......" Kip complained over the radio, "God~ my windshield is going to freeze!" ”

"Try spraying alcohol on your head. This prevents the glass from freezing and cracking. Zhang Yun said as he asked George in the co-pilot to do the same.

Their situation was even worse than that of David and Kip, the outside of the plane was covered in ice, even the propellers, and nothing could be seen from the outside, as if they were flying in an ice kiln. The automatic indication of the on-board radio compass was also disabled.

The situation is starting to get dangerous!

You must know that they are now crossing the valley, the valley here is circuitous, the maximum distance between the peaks on both sides is just enough for a plane to pass through, and now there is nothing to see, so what awaits him is only the fate of hitting the mountain!

"It doesn't seem to work...... George gestured to their windshield.

Zhang Yun hurriedly sprayed all the remaining alcohol on the glass, and the situation finally improved a little, and now he could see out the window, but the visibility was still outrageously low.

"Damn it!"

He turned the loop antenna on the plane—a tool used to test the plane's bearing, and it had to be adjusted from time to time to prevent it from freezing, or they would go off course—and it had only been a few moments before a frost had formed on the antenna and it had almost failed.

The successive failures made Zhang Yun scramble, and on the contrary, the radio was full of complaints from partners:

"Jon, is your electricity still holding up?"

"It's almost gone, and there's a problem with the hydraulics - what about you, Davy?"

"My fuel injector is frozen!"

Zhang Yun quickly glanced at his oil temperature......

"Good thing the engine is fine......" he sighed happily.

Who knew that the voice fell, and suddenly the engine "horn" fired a few shots, and Zhang Yun's face changed involuntarily.

The carburetor is frozen!

"We've got to climb up to the clouds!" Zhang Yun couldn't help but shout into the radio communicator, "Solar energy helps us alleviate the freeze." ”

"Tell me, how do you climb up when you're on a plane with an elephant on board?" David complained, "I feel like a snail right now, and I've reached the limit of what I can climb to this height." ”

The C-47 would have had a ceiling of only 5,000 meters. As a result, in order to carry a little more supplies, he made the entire cabin almost full, resulting in the plane being seriously overloaded now, and it can only climb to about 3,000 meters, which cannot exceed the height of the mountain peak at all, and can only travel through the valley.

Zhang Yun frowned secretly, what David said was the truth, in order to transport a little more, he stuffed each plane with supplies, and it was unrealistic to forcibly climb.

He looked at his dashboard again, the heating system was flashing a warning red light, and the outside temperature was -30 degrees Celsius......

"You have to think of ways to warm up the plane, otherwise you won't be able to hold on to Tingjiang ......Airport," Zhang Yun was secretly anxious.

He looked out the window again, and the thick clouds were low on their heads, blocking them from the sun and from hope, like an endless wall of scale, locking them up in this icy and snowy world.

Zhang Yun suddenly noticed a glimmer in the distance!

Like an apocalypse, a golden light pierced through the clouds at 3 o'clock in front of it, refracting dazzling light on the huge snowy peaks!

"See there?" Zhang Yun shouted excitedly, "Let's fly there, the sunshine can help us get out of trouble!" ”

※※※

"Jon~Look!" George suddenly shouted as if he had discovered a new world, "Three o'clock on the left!" ”

Zhang Yun raised his head, and a brilliant light was floating in the sky like a ribbon, flickering dark and bright, emitting red, blue, green, and purple light. Sometimes it looks like a beautiful column towering overhead, and suddenly becomes a tent that is opened, and then quickly rolled into spiral strips, magnificent and moving.

"It's beautiful, isn't it? Buddy? David couldn't help but exclaim.

Zhang Yun's face suddenly changed.

"Get out of there now!" He shouted hysterically at the telecomm, decisively left behind the few remaining enemies, and rushed out without looking back.

"What's going on, second lieutenant?" David was inexplicable.

"Stay away from the clouds!"

"But ......"

"Lower your flight altitude! Immediately, immediately! Zhang Yun shouted, while increasing the throttle to the maximum, his "banshee" swooped down like a sharp arrow into the air.

"Why?" George also didn't know why, "the sun can only get above the clouds......

"If we don't run, we'll all die!" Zhang Yun shouted, "Didn't you find out? It's the aurora! ”

"yes."

"But this is not Antarctica, where does the aurora come from?"

"This ......!"

"Won't it?"

In the radio communication device, David and Kip gasped at the same time: they were reminded by Zhang Yun like this, and they realized that something was wrong at the same time.

"It's high-altitude electrostatic discharge!" Zhang Yun began to press down the head of the machine desperately.

"You mean ......"

"Thunderstorm!"

As if to confirm his words, the sky, which had been clear just now, darkened in an instant. The originally peaceful auspicious clouds quickly gathered together, forming a huge mushroom cloud, black and gloomy, the black cloud electric snake away, from time to time there was a heavy thunder, like a huge wheel running over the glacier, making a terrifying popping sound.

All the pilots turned pale, and even without looking, they could feel how terrifying the power contained in the clouds was.

"This, how can it be ......?"

"Whatever it is! Execute the command! Pay attention to the instrument and don't look outside! ”

In the communication instrument, Zhang Yun shouted again, waking up his comrades-in-arms who were still in a daze.

But it's too late!

A bright lightning bolt split the gloomy curtain, and a piercing thunderstorm descended with the horror of the apocalypse!
