It's a laboratory full of precision instruments, and all kinds of equipment run around the clock.

In the center of the laboratory room, a large light screen stands. It was constantly beating with dense numbers, which was a huge amount of calculations, not to mention how long it had been counting.

Strangely, the huge laboratory was empty, except for the "humming" sound of machines.

"Ahem." Voices came, from far and near.

The door of the laboratory quietly opened, and an old man in a white coat walked in.

Although he was full of gray hair, the old man was still in good spirits, and the wind was blowing under his feet.

He stared at the data on the central light screen, unable to take his eyes off it.

"It's coming! Soon! The old man muttered to himself. The 'original blood' purification algorithm is coming out soon. ”

He was overjoyed and couldn't help but dance.

"But—" The old man frowned, looking at the light screen. Donor activity is declining, which interferes with the speed of computation. ”

After pacing in place for a while, he had an idea.

I saw his ten fingers flying, constantly tapping on the projection keyboard in front of him.

"After waking up the donor, we had to use virtual reality."

......

Underneath the laboratory, there is another cave.

In the basement of more than 100 square meters, there is only a young man lying quietly in mid-air, and there is nothing else.

It's just that the surrounding walls flash from time to time with flickers of light and unknown characters, showing that this place is unusual. If you look closely, you can see that the entire basement roof and floor walls are made of the same material.

Suddenly, a dream came out of the young man's mouth.

He has black hair and a small head, an ordinary appearance, but a pair of thick eyebrows, wearing a white T-shirt and black sweatpants, quite fresh and handsome.

As he became more sober, the frequency of characters flickering on the walls around him increased significantly, and in an instant, the otherwise empty room was filled with light and mist, slowly outlining the 21st-century hospital ward setting.

The young man's eyes slowly opened, revealing a burst of confusion in his eyes.

"Who am I?" He frowned.

Struggling to raise his arms, which had become extremely thin after a long period of inactivity.

Looking at the familiar and unfamiliar pair of slender and thin hands like a woman in front of him, he was at a loss.

"I am... Square... Square... Hiss... Fang what? ”

"Huh? Didn't I fall into a hole and run out of ammunition and fall unconscious? The last fragment of his memory flashed away, and he struggled to sit up, looking at the familiar scene in front of him.

"Hospital? I was saved. He let out a long sigh. Oh yes, I'm Fang Yan. ”

Fang Yan, who thought he had figured everything out, relaxed and lay down again.

"Where's my phone? What about my parents? He wondered.

"The phone is frozen, as for my parents...... They are busy every day, so they probably only come in the evening, and maybe they only have time to come and see me on the weekend. Fang Yan smiled bitterly, as the eldest son in the family, he couldn't know how busy his parents were with work.

"I miss my childhood, although my family is poor, at least my parents are around, and my life is happy. Later, when they grew up, the conditions at home were better, the furniture was changed and changed, and the clothes were better and better, but they were too busy every day to see no one, alas. Fang Yan sighed.

"As for Xiaomei, she should be in school now, her grades have always been very good." He fell into memory.

In contemplation, Fang Yan couldn't help but think of the scene when he was killed......

In the ice and snow, he carried a travel bag on his back and walked alone against the cold wind blowing like a knife blowing in his face. As he was walking, a touch of red appeared in his sight, which he didn't pay attention to at first.

"I guess it's garbage thrown away by tourists." He thought to himself.

It's just that as the distance closes, the red shape becomes clearer. Slowly, Fang Yan saw clearly, it was similar to the shape of the human body.

His head shook with a "boom", and he couldn't help but take a breath of cold air, and his thoughts were full of distractions.

"Call the police! Save people! ”

He hurried to the "man".

As he got closer, Fang Yan's footsteps became more and more hurried, and gradually, he saw the true face of the red object.

Stomping his feet fiercely, exhaling heavily, Fang Yan said with a toothache: "Who is this, throwing clothes everywhere!" Scared the hell out of me. ”

Suddenly, there was a "click".

He looked around vigilantly, and there was nothing wrong with the white expanse in front of him.

However, "click", "click" and "click" sounded again three times in a row.

Fang Yan suddenly looked at his feet, and the scene in front of him made his scalp tingle.

He's standing on top of an ice field!

This ice ground is not thick, but it has been overwhelmed by the stomp he just had, and there have been many cracks. Horrifyingly, the rift is still growing!

Before Fang Yan could make a move, a strong sense of weightlessness struck, and with a scream of "ah", he disappeared into the hole where the ice was cracked.

Only the terrible screams remained, enduring, and the aftermath was lingering, which can really be described as "those who hear are sad, and those who see are crying".

In the cave, Fang Yan was lying on the ground in the shape of a "big", secretly saying in his heart that it was dangerous, fortunately he was dressed thickly, and the cave was not deep, but it was just ......

Looking at the steep mountain wall, smooth as if it had been polished for countless years, his heart sank.

"If I knew this was the case, I wouldn't have come to climb Mount Everest in the first place."

"Who is so boring, throwing away all the clothes!"

He was very aggrieved, and countless negative emotions were blocked in his heart and wanted to vent.

He pulled out his phone hopefully. When he saw that there was still a single signal left on the mobile phone, he really realized what it was to be "happy".

He couldn't wait to call for help, his hands were shaking. However, no sound came from the intercom hole.

"What's the situation?" He stared at the signal bar on the screen.

After a few seconds, the remaining signal grid disappeared......

His face suddenly turned to ashes. It turned out that the mobile phone grid was not refreshed.

Staggering to his feet, he looked around.

The cave is not large, the whole is cylindrical, and can only accommodate four or five people. The cave was empty, and there was no view of it.

So, he began to count his backpack, estimating how long he could last with his frugality.

With each count, the dim hope in his heart brightened.

In order to conserve his strength, he lay motionless, but his mobile phone was clutched tightly in his hand.

It was cold at night, and even though he was wearing a thick coat, he was shivering and shrunk into a ball.

This night was extremely difficult.

After dawn, he dialed the distress number again and again, hoping that there would be a 1 in 10,000 chance to be reached, and what he waited for was constant disappointment. As a result, the light of hope dimmed.

Day 1, Day 2...... Day 10.

There were ten scratches carved into the ground, and he curled up to the side. For ten days, he tirelessly called for help, and it was no different today.

He picked up the phone with the only strength he had left, but slowly put it down, his eyes gloomy.

"Life is precious." Licking his cracked lips, Fang Yan was desperate. "It's fate."

After a long time, sleepiness hit him like a tide, and he muttered to himself: "Dad, Mom, little sister, you... Be nice..."

Soon after he lost consciousness, endless snow poured in from the mouth of the cave, burying his cold body and gradually filling the entire cave.

......

When he came back to his senses, Fang Yan was full of emotion.

"It's incredible, it's like a dream, life and death have gone through it...... Well, it's good to be alive! ”
