After learning that Pluck was about to rob his small shop, Oroboros and Yuffie quickly hung a price tag on the container. The price listed above is exactly the price in YGGDRASIL in Oroboros's memory. Although it is not known whether the price of YGGDRASIL is cheap or expensive compared to the price of this world, it will at least disappoint Pluck, who is expecting to rob him.

"Hey, Slya, have you come back from the appraiser? The medicine we give you is not really effective! ”

Slya lowered his head, took the potion out and put it on the counter of Oroboros, then turned to leave.

Seeing Slya suddenly make such a move, it really surprised Oroboros: "Hey, hey, Slya. What do you want, why don't you buy my medicine? Do you think my medicine is fake? ”

Slya turned around and smiled reluctantly, "I'm sorry, Mr. Storekeeper, your medicine is indeed real. I have appreciated your kindness...... It's just that the medicine you gave me is indeed too expensive, and I can't take your medicine. Maybe there will be people who need him even more......"

"Smack, smack, smack!" Olobros slowly puffed up his palms, then handed the vial up, "Young man, I am so touched by your honesty. You can take this bottle, I gave it to you. Just pour this potion into a cauldron and dilute it, and you should be able to save your entire village from the zombie plague. ”

"No, no, even if it's just a bottle of potion, its value is definitely not something our village can afford." Under the astonished gaze of Oroboros, Slya rejected the gift from Oroboros.

Looking at Slya's sincere gaze, Oroboros was once again surprised. If he says that he will return the potion for the first time, it may be that he understands that he is purely fooling himself (Author: Your personality is a bit bad...... ）； Then rejecting himself for the second time can at least show that at least he is not a greedy person.

"Okay, I see what you mean...... "Oroboros held out his hand, "You gave me all the money in your hand, and I'll help you out!" Don't look at me like this, the magic of expelling the zombie plague, I have also learned! Do you think it's a good deal? ”

Hearing Oroboros's words, Slya showed an incredulous expression, "Mr. Store, are you serious?" ”

"Seriously, of course. Otherwise, do you think I'm idle enough to open a small shop for, isn't it just because I don't seem to have anything to do? Now that the interesting things have come to the door by themselves, then nature must not be abandoned! ”

(Author: I really want to say such things happily, how can I cultivate it!) ）

"Huh?"

---------------------------------------------------------------------------------------------

The camera pans to Oroboros and Yuffie lying in a carriage. They chewed on the dogtail grass and looked up at the sky, watching the clouds slowly drift past their eyes. A breeze swept across Oroboros's cheeks, and he could smell the fragrance wafting from Yuphie's body.

This fragrance can't help but make Oroboros think about it, as a man of two lives, Oroboros has never had any girls so far. Just as his dishonest hand was about to reach into Euphemia's skin, the carriage under them seemed to press against a stone on the side of the road, and then the whole carriage shook with a "clang", and the plank of the carriage hit the back of Oroboros's head.

"It hurts, it hurts, it hurts!" Auroboros sat up from the carriage, clutching the back of his head. Seriously, the whole road, Oroboros has been bumped by this medieval country road and his head is about to be shattered, which makes Oroboros feel like he has returned to the nineties.

When Oroborose was a child, his father often rode his bicycle to take him to his grandparents' houses in the countryside. Whenever you get close to your grandparents' village, the dirt road is bumpy and numb.

The path leading to my grandparents' house is only about one meter wide, and this kind of road used to be called the production road. Such a road cannot even be walked by tricycles, at most only bicycles. The road second only to the production road is called the field road, and the width is about three meters. Although it is not very wide, it is at least more accessible than the production road.

"Sliya, how far is your village?"

"Mr. Oroboros, in my experience, it will take at least another half a day to walk. Rest assured, I promise to arrive in the village before nightfall. ”

"What the hell does your family live in, and it takes half a day? If this were on our side, half a day would be enough time for me to soar from Beijing to Shijiazhuang! Aloborose lay down again in frustration, then pulled his phone out of his trouser pocket and started playing.

As a "world-class prop" made by Oroboros with his position authority, the Alternate Dimensional Slate, Oroboros does not have to worry about his mobile phone being unable to connect to the network, running out of power and damaged. Even this mobile phone has a special function of automatic update system and function, which ensures that even if the network and mobile phone system of another world are updated, his mobile phone can keep pace with the times and will not be unable to play new games.

In fact, even in the 22nd century, where games have been developed in the brain, games that rely on computer and mobile phone screens are still stubborn. This is mainly because the development cost of brain games is too huge, and in the 12 years of the birth of brain games, there are no more than 30 brain games in total. Such a scarce quantity naturally cannot fully meet the needs of a huge number of customers. In addition, the purchase price of the in-brain game console is also quite huge, so the in-brain game console does not completely occupy the entire group of gamers.

On top of that, some in-brain gamers are also stubbornly playing flat games on computers and mobile phones out of nostalgia. This allows flat games that have been around for the last century to survive tenaciously in the new century.

In addition to hobby factors, there are also some players who are not willing to play brain games at all, or are not able to play brain games at all. The reason why they are not able to play brain games is because their brains have certain defects of their own...... It's not that they have mental illnesses, it's that their brains can't adapt to the game system in the brain.

I believe everyone should have played "CS" and "CF", and everyone should have experienced nausea and vomiting when playing "CS" and "CF" for the first time.

This condition is called 3D gaming syndrome.

When you're playing first-person shooting, the screen is constantly rotating and your body isn't moving. At this point, the signals sent by the eyes to the brain conflict with the signals sent by the body to the brain, so the brain sends a signal to stop the conflicting behavior. Some people suffer from severe 3D dizziness in first-person shooter games, and this symptom is basically insurmountable (even for long periods of gaming and exercise). The way to reduce this is to play this game without focusing too much on the screen, and try to zoom out as far as possible. Ensure that the surroundings are well ventilated. And play for a while before resting. The same is true for motion sickness. The scene you see is constantly moving, and your body doesn't feel it, and this conflict can cause nausea and want to vomit.

Similarly, in the 22nd century of King of the Undead, brain games will give birth to a condition similar to 3D game syndrome, and it is more dangerous than 3D game syndrome.

Humans in the 21st century will vomit when playing first-person shooters. However, in the DMMO brain game of "King of the Undead", human beings may have a disorder of the body, that is, the phenomenon of the nervous system partially or completely losing control of physical skills.

When humans are playing intense exercise in the middle of a game, the human body does not actually feel any external physical stimuli, but the brain feels a wealth of stimulus information. As the main control organ of the human body, once the brain receives this information, the body will respond accordingly under normal circumstances, but at this time, the body has no problems at all. At this time, the information that the human brain is exposed to will conflict and contradict the confidence that the body receives.

If playing a first-person shooter game only causes vomiting, then playing a brain game can cause more discomfort to your body, which can lead to breathlessness, incontinence, visual confusion, auditory confusion, motor dysfunction, cerebral disorders, and in the worst cases, direct death.

Although the world of King of the Immortals is the 22nd century and the world of Sword Art Online is only the 21st century, the brain game of King of the Immortal is completely behind the brain game of Sword Art Online in terms of development level.

In the world of Sword Art Online, human beings can perfectly replicate the human senses, whether it is sight, smell, taste, touch or hearing, all of which can be perfectly displayed in the game world. However, in the world of "The Immortal King", only the three senses of sight, hearing, and touch can be realized. Among them, the sense of touch is only generated by a moderate computer simulation, and it is completely impossible to achieve a perfect reproduction.

So why is it that in the world of "The Immortal King", humans in the 22nd century can't perfectly reproduce the senses of touch, taste and smell?

In the real world, Oroboros, who has worked on DMMO research projects, knows that if players are allowed to experience the senses of sight, smell, taste, touch, and hearing generated by the game in their brains, it is likely to kill people instantly.

This is because the brain simply cannot directly carry the huge amount of information generated by the computer.

The cerebral cortex can be divided into five functional areas: mental functional area, visual area, auditory area, body sensory area, and language area.

In daily life, the five senses are all informed by different organs of the human body, such as the visual area through the eyes, the auditory area through the ears, the nose for smell, the tongue for taste, and the sense of touch (below the neck) through the spinal cord.

Brain games are different, brain games directly cover the human cerebral cortex by simulating brain waves, so that the cerebral cortex can feel additional information beyond the body information.

On an EEG, the brain produces four types of brain waves. When you're in a state of stress, your brain produces β waves; When your body is relaxed, your brain is more active, and your inspiration is continuous, you are exporting α waves; When you feel drowsy, your brain waves become theta waves; When you fall into a deep sleep, it becomes a δ wave.

Different human senses obtain information through different channels, but brain games only transmit information through one channel. With the current means, it is only a simulation of sight, hearing and some touch, if all the senses are perfectly reproduced, then the brain waves generated will directly burn the brain!
