The brain of living beings needs to rest, in the same time, the energy utilization rate of the brain is the highest, such a high-efficiency operation can not be carried out for a long time, by entering the state of no thinking to reduce the operating power and energy consumption of the brain, the regeneration rate of brain cells can exceed the death rate, in order to maintain the basic functions of the brain.

On an earthy yellow planet, under the primeval sky is the primordial earth, and the primordial earth has a family of primitive people.

As the pillar of the family, Puff sat at the door, looked up at the stars in the sky, chewing half of the barbecue cooked by his daughter himself a long time ago, and now there is no meat taste, but he just can't swallow it, it turns out that his brows are tightly locked, and he has troubles in his heart.

Ahh His wife came over and sat with him.

Simultaneous translator: Ah, what do you think, you don't seem happy?

Oh, goo, hey, goo

Simultaneous translation: Alas, I didn't think about anything, I didn't have anything to eat at home, and I wanted to go out and hunt animals.

Huh? Whoa, whoa, whoa.

Simultaneous translation: Evening? Animals will eat you.

Mi-hmm-huh.

Simultaneous translation: I'll hit it from a distance.

Yo buzz hey.

Simultaneous Translator: Then you go and come back quickly.

Miao!

Simultaneous translation: I will!

Puff had already sharpened the spear, and was very satisfied with the sharpness of the spear, so he decided to try the power of the spear and show it to his wife.

Picking up his spear, he strode forward, climbed hill after hill, crossed a small river, and almost washed away his trousers, and came to his destination in danger and danger.

This is a paradise, the only habitat within a radius of tens of thousands of kilometers, here, there is no shortage of ferocious animals, tall and heat-resistant trees protect the fragile flowers on the ground, the green space is overgrown with thorns, if you want to enter the woods, you must either fly over, or rush over, for Puff, it is impossible to fly, rush over and your life will be gone, you can only pull out the thorns little by little, make a small opening.

At night, he couldn't see anything, and his hands were bleeding, but he didn't feel the pain, because when the branches on the thorns were broken, they would secrete a kind of mucus with a paralyzing effect, but the paralysis lasted only half an hour, and once the paralysis effect disappeared, the light ones were in unbearable pain, and the heavy ones fainted in pain, and the little life that bleed too much was gone.

Puff estimated the time, he had to find the prey within half an hour, kill it, and take it home, otherwise, once he passed out, he might not be left with the whole corpse.

With a half-effort, Puff rushed through the thorny defense line and slipped into the woods with his waist down.

There are only a few animals in the woods that are suitable for hunting, and they all live in groups, and it is not easy to find a lone one in the dark, but as long as the speed of the puff is fast enough, it can escape before the other animals react.

It was a little wild boar, sleeping sweetly next to its mother, and poofed twice and gave up, because even if it was a little wild boar, it was not something that could be lifted by itself.

There are three rabbits there? Puff Cat was in the grass, looking at the three little rabbits bouncing back and forth not far away.

Puff only has one spear, he only has one chance, in terms of probability, he can kill a rabbit 100%, there is a 50% probability of killing two, and a 30% probability of killing three.

Take a gamble! Puff gripped the spear tightly as she noted down the movement of the three rabbits.

After watching it for a long time, Puff didn't find that there was some kind of cycle in the movement of the three rabbits, and they were all arbitrary.

Puff didn't want to wait any longer, at this time he already faintly felt the pain in his arms and legs, and when he saw the three rabbits walking in a straight line again, Puff made a move.

Sou! Poof!

The spear arced through the air in a perfect arc, piercing the rabbit one after the other, and finally clicked and slammed diagonally into the ground.

Yes! Poof, he shouted, then quickly covered his mouth, smiled, and hurriedly walked over.

The bird, which was still asleep, was awakened and flew out with a hula and a hula.

The four little short legs of the little wild boar kicked hard, and the mother wild boar kicked the father of the big wild boar who didn't wake up with one hoof. The father of the big wild boar licked the saliva on the side of his mouth, and looked at his wife, who was half older than him, for some reason.

Animals roared in the woods, and Puff was so frightened that before he could remove the rabbit from his spear, he slipped away through the tall grass.

I got lost, and I walked for a long time, but I didn't find the opening I had made on the edge of the thorns, and the pain in my body became more and more intense, and I began to tremble. Puff found a bunker to hide herself in, spread a layer of grass underneath, and lay down on it, ready to spend the night here.

After a while, drowsiness hit, and the pain exceeded the limit of Popo's tolerance, and he passed out at once.

Puff came to a place that seemed to be a dream, but it was not the same colorful scene as before, only pitch black.

Poof, he couldn't see his hands, he couldn't see his stomach, his legs and feet, it was as if he had only a brain floating in the air, maybe not even a head.

Whew!

At this moment, a glowing slit appeared not far ahead, and then the slit opened to both sides, as if someone had opened a window outside, and I saw two people wearing white masks and white coats standing there.

Puff wanted to get a closer look, and as soon as the thought came to him, he felt like he was slowly drifting towards the white window.

As he got closer, he overheard the two men talking, but he couldn't understand them.

How's it going? The less haired one asked the slightly younger one with the glasses.

At present, this primitive man is in a coma, but there seems to be something wrong with his physical functions. The man lifted his glasses and looked at the older man with less hair.

Oh? What's the problem?

You see, here, first of all, his heartbeat, here, his heart beat 138 times a minute, and now, it is only 7; There is also this, the breathing rate, even more scary, it used to be a breath every 4 seconds, but now I can't exhale a full breath for a minute; And this, with this, the display has dropped.

Is this a state of deep sleep or even hibernation? Asked with less hair.

No, it's a little deeper than that, you see, it's his brain waves, it's already trending in a straight line, so to speak, there's almost no brain activity anymore, it's about the same as brain death, the only difference is that he's still alive, but he's more vegetative than a vegetative person.

Wait a minute, is this what it is...... Is it a state of brain separation? The hairless one jerked up at the bespectacled one.

Well? I'll take a look at it again. Professor, really...... It's really a state of brain separation! The glasses checked the data again, and were surprised to compare it with what the theory said.

It's amazing, I didn't expect it, I didn't expect it, I actually found brain separation in a primitive man who was about to die, I always thought it was just a theory, but I didn't expect the reality to really exist, God help me! The more he thought about it, the more excited he became, and he couldn't wait to tell the world that he was the first to discover the state of brain separation!

Only one day later, the scientific journal published the professor's paper, which caused a huge sensation in the medical community, and for a time various media and advertisements followed, busy but happy.

A week later, a pharmaceutical company approached the professor and wanted to talk to him about the separation of the brain.

A month later, under the leadership of the professor, the pharmaceutical company developed a drug called Itsumon. This medicine allows a person to fall asleep in a short period of time, is more effective than any previous sleeping pill, and does not have any side effects. The only downside is that the price is a bit high.

A year later, the drug was already being sold in large quantities across the country, and it was a boon for insomniacs.

After three years, the effectiveness of the drug began to decline, and some people began to vomit and dizziness after waking up.

Immediately afterward, the pharmaceutical company released an upgraded version called Dream Spirit II. As soon as it went on sale, it quickly sold out, and it was very popular.

Five years later, the professor couldn't sleep at home. On the table next to it was a bottle of Dream Spirit II, which was empty.

With this drug, this pharmaceutical company opened branches abroad, and for a time, it became the focus of attention all over the world.

It didn't take long for the prescription for the drug to be stolen.

Seven years later, six pharmaceutical companies around the world have started selling the drug, but the name is no longer called Imemor.

People are already inseparable from the Dream Spirit, and they must eat two pills before going to bed to feel at ease. Over time, some people accidentally find that their reactions seem to become sluggish, their fingers are not as flexible as before, they feel like they can't run when they walk, and sometimes they even stop thinking.

It has only been since tens of thousands of car accidents that people have begun to take it seriously. At this time, people found out that this drug has a huge side effect, that is, it will make people become slower, and even make various movements extremely slow, as if they are slowing down the camera.

Later, after more than a dozen scientists' research, it turned out that the working mechanism of this drug is to produce an inhibitory membrane in the cerebral cortex, which will delay the transmission of brain signals. As the dosage increases and time passes, this membrane will become thicker and thicker. Now, the membrane has begun to block brain signaling. The end result is that people stop moving, and only the brain is left to keep the basic functioning, your breathing, your heartbeat, your blood circulation, and all the other systems are kept to a minimum, so that at least you don't die right away, but the end is miserable.

Even if you find out the side effects of this medicine, it is too late, and even if you stop taking this medicine from now on, the inhibitory film will not disappear.

Decades later, those who had never taken the drug stood in front of the tombstone of the last person who died because of the inhibitory membrane, looking at the words engraved on it and sighing.

Dreams are meant to wake up after all, but after waking up, is it a dream or a reality?

Finish.
