Severe brain pain accompanied by a concussion-like sensation of vertigo, which was the first sensation 74328 felt when he woke up, and before he could react otherwise, the vomiting response caused by the vertigo began to work in his body, causing him to vomit everything in his stomach.

To make matters worse, his body was limp and weak, and he didn't even have the strength to do it, so he could only deflect his head a little and vomit all the vomit on the side of his head.

After the vomiting response subsided, the dizziness in 74328's head was slightly relieved, but the headache persisted, and became more intense due to the lack of a counterbalance to the dizziness.

"The first brain, check for abnormalities in the brain. The intense physical discomfort caused a trace of concern in 74328's heart, prompting him to immediately order the first brain, who was in charge of controlling the body's organs, to check his physical condition.

However, things didn't seem to go the way he thought, and after he gave the order, his first brain didn't react, as if the first brain had disappeared.

74328, who had a bad premonition in his heart, immediately began to give orders to the second deputy brain responsible for logical deduction and the third deputy brain responsible for learning and organizing respectively, but the results obtained were the same as before, and there was no response.

Just when he was a little overwhelmed, a large number of chaotic memory fragments instantly poured into his brain, causing a strong impact on his spirit, making his already painful brain even more painful.

The pain could not be described in words, and if his body was paralyzed and weak, perhaps he would have committed suicide by hitting the wall because of this intense pain.

The pain appeared and disappeared quickly, like a wave of the ocean, and after this peak it quickly abated and returned to normal levels.

"Damn!" 74328, who had recovered his strength, felt that his brain was filled with all kinds of messy memory fragments, and he had to use what little thinking ability he had left to analyze the current situation, and soon he had an answer, and this answer was very bad for him, and even made him break through the rules of behavior that he had cultivated for many years, and he couldn't help but curse secretly in his heart.

Because he found that the current severe pain in the brain, the disappearance of the three auxiliary brains, and the appearance of so many chaotic memory fragments in the brain, etc., all pointed to a bad possibility, that is, the collapse of the auxiliary brain.

Since the appearance of splitting the brain three hundred and forty-five years ago, there have been as many as 100 billion people using splitting the brain to create the accessory brain, and there are many cases of accessory brain collapse, and the Earth Federation has set up a special archive for this purpose to collect and sort out the information of the parabrain collapse.

There is no public opinion on the cause of paracerebral collapse, some say that the paracerebral is overused, and some believe that it may be that the brain splitting surgery has a congenital defect and is not suitable for a certain type of people, but the only thing that can be determined is that the phenomenon of paracerebral collapse is irreversible after it occurs.

The only way to address the side effects of paracerebral collapse is to reapply splitting the brain to create a new parabrain.

However, the difficulty of an ordinary person using splitting brain to create a parabrain and a parabrain collapse are completely two levels, and there are only two successful examples so far, and these two examples cannot be considered successful, because the auxiliary brain they created does not have any function of the auxiliary brain.

Although there is no successful case, there is no second way for the current 74328, because even the so-called robot is not confident that he can withstand the impact of the next wave of side effects.

So, after making a decision, the decisive 74328 began to skillfully use splitting the brain to segment the neurons in the brain.

Brain splitting is a magical evolution method created by a mysterious scientist in the old era of the earth more than 300 years ago, this method contains not only occultism, but also psychiatry, brain science and other human science, it can be said that this technology has made human beings leap a big step in evolution, from a single earth creature to a real cosmic race.

According to the Earth Federation, the basic theory of splitting the brain should have originated from a thesis of a neuroscience student at Harvard Medical School.

In this paper, the student conducted a holistic analysis of the utilization of the human brain.

He thinks that the use of the brain by human beings is very low, and even the most intelligent people do not use more than 20 percent, and believes that the reason for this is not that human beings cannot use the other 80 percent of the brain, but because of the inert genes in all living things, which make it impossible for human beings to effectively use the other 80 percent of the brain.

Inert genes were a new concept at the time, and some genetic scientists found that there is a common gene in the genomes of all organisms, including humans, which can make organisms lazy, so scientists named it inert genes.

Before that, most scientists thought that laziness was caused by personality, but it was only after the discovery of the inertia gene that humans realized that it was this gene that was at work.

For example, as long as the mouth is opened, a certain organism can meet all the needs of survival and desire, so the organism will no longer make effective use of other body organs other than the mouth.

The human brain is also affected by inert genes, and if the human brain utilization rate is enough to meet the needs of life now, then the remaining 80% will not be used.

After discovering that the inert genes of humans make it impossible for humans to use their bodies effectively, some scientists on Earth began to find ways to solve this problem, and many of them had bold ideas to strip the inert genes from the body's genome, but they all ended in failure.

This question of human evolution was broken more than 300 years ago, 50 years before the establishment of the Earth Federation.

A mysterious scientist did not study inert genes like others, but bypassed the problem at the genetic level, directly targeted the most core part of the human brain, and created the brain splitting technique, which splits the most ineffective brain resources in the human body and turns them into biological auxiliary brains that assist the main brain and control the body.

In this way, the extra auxiliary brain can not only allow human beings to obtain unimaginable computing capabilities similar to super quantum computers, but also enable human beings to manage their own body organs almost perfectly like computer management hardware, so that human beings have evolved to a point that was unimaginable in a short period of time.

After the scientist created and perfected the splitting brain, he directly released it to all countries on the planet, so that anyone with access to the Internet could get the complete method of using the splitting brain.

Splitting the brain is naturally a good thing for all humans, but it is definitely a poison for those in power.

After all, in an era where everyone is like a dragon, there is no difference between those in power and other people, and it is almost impossible to control others, so when the splitting brain technique was announced and confirmed by many people to be effective, the situation on the entire earth began to be turbulent.

There is a protracted war between and within the nations of the planet because of the division of the brain, and no country is immune.

It wasn't until the earth was devastated by the war that everyone realized that if they continued like this, everyone would be doomed, and finally the countries of the earth abandoned their previous hatreds, and the human race also abandoned their grudges, and established the only country on the earth, the Earth Federation.

After the establishment of the Earth Federation, people found out at this time that they still don't know who the creator of the splitting brain is, and this person has not left any name and identity information, and this matter has become one of the biggest mysteries within the Earth Federation, and there are a lot of speculations around this mystery, including conspiracy theorists.

For 74328, what kind of purpose did the creator of the splitting brain technique have to make it public, what is the meaning of the splitting brain technique to human beings, and all other questions are not for him to consider, in fact, as a biological weapon of the Earth Federation, most of the things he needs to consider are how to effectively hunt down the enemy and kill it.

It is precisely because of the extraordinary endurance of biological weapons that he can withstand that extreme pain, and under the influence of various adverse reactions, he can still successfully use brain splitting to separate 20% of idle brain neurons and combine them into a new accessory brain.

"Function settings!"

"Body control!"

"Check your body!"

"Organize your body data!"

"Build a database!"

"Adjust the structure of the brain!"

"Tune in on memory cells!"

............

At the moment when the auxiliary brain was formed, 74328 skillfully issued one instruction after another, and according to the previous usage habits, the first auxiliary brain was classified as a body control secondary brain, and began to check the physical condition.

At the same time, with the production of the parabrain, the sharp pain and dizziness in the head also weakened as quickly as the tide receded, because the other senses of the body weakened by the pain and vertigo also began to recover, and he began to perceive the situation in the outside world.

"War!" The first sense of smell and hearing was restored, so that 74328 instantly understood the environment he was in, and he also had strong doubts in his heart.

The smoke of gunfire, the sound of gunfire, the chaotic shouting around him, and all the information that comes together from the senses of smell and hearing, all indicate that he is now on the battlefield.

However, the problem is that since the Earth Federation entered the interstellar age, gunpowder weapons have become extinct, and the weapons used by armies and individuals are all more convenient and powerful Gaussian weapons, ion weapons, and so on.

Gunpowder weapons have long since become private hobby collectibles, like some other earth-age items, and will never be equipped and used on the battlefield on such a large scale as they are now.

Just as 74328 was about to open his eyes to look at the surrounding situation, a cannonball hit not far from where he was, and the air wave generated by the explosion of the cannonball spread out in all directions, lifting him off the ground, and then slammed it to the ground, and a sharp pain in his abdomen came instantly.

Far from terrifying 74328, the pain in his body awakened his combat instinct as a biological weapon, allowing him to skillfully adjust his body posture to reduce the squeeze of the injured part of the explosion just now, and avoid causing secondary damage.

However, apparently his luck was not good, and just as he was about to try to open his eyes to check the injuries on his body, a man suddenly appeared beside him, grabbed his arm, and dragged him vigorously regardless of the injuries on his body, and after dragging him for a distance, he put him down, and then slapped him on the cheek roughly, peeled off his eyelids, and checked on his condition.

The eyelids were forcibly peeled off, causing a burst of pain in the eyeballs that had not yet fully adapted to the situation, and 74328's tears could not help but flow out.

And when he felt the tears flowing out, 74328 was even more shocked in the depths of his heart, because he was sure that as a biological weapon, after the eyeball was transformed, the tear glands had been stripped away, and it was impossible for him to shed tears.

After tears moistened the eyeballs and took away the adverse effects caused by forcibly peeling off the eyelids, the blurred images reflected in the eyeballs began to become clear.

The first thing that caught my eye was a big man with a beard and distinctly Celtic features.

I saw that this person was wearing a torn military uniform, judging from the style of the military uniform, it looked like the British military uniform during World War I in the old era of the earth.

The messy head wore a military hat that was completely disproportionate to the size of the head, and there was also a hat on the hat that was supposed to represent the army or the president of the country, but 74328 had never seen such a strange badge, because the symbol on the badge turned out to be an octopus.

“*&（......*&%*”

After seeing that 74328 was sane, the soldier laughed a few times, then slapped him on the shoulder like an acquaintance, said a few words of encouragement in a language he had never heard before, and then picked up a very old-looking breech gun on the ground and ran out of cover.

Since the view is no longer blocked, 74328 can also clearly see the surrounding situation.

He was now in a bunker made of trenches, which resembled the deep trenches of the First World War, and the bunkers were built with logs on both sides of the ditch and a layer of dirt on them.

The function of this bunker is only to cover a little dust falling from the air, and it has no defensive power in itself, and it can be easily destroyed by a single shell, at best giving the people staying in the bunker a psychological comfort.

At this point, the bunker seemed to have been turned into a front-line hospital, and a large number of patients similar to 74328 were lying in the bunker, and several people wearing strange masks who looked like doctors were checking the injuries.

After scanning his gaze in the bunker and taking in his surroundings, 74328 withdrew his gaze to himself and looked down slightly at his hands and body. When he realizes that the shape of his hands and skin color have completely changed, and he wears a military uniform that he has never seen before, he begins to realize that he may have encountered something almost legendary, a time of rebirth.
