With the technology to realize virtual reality, what needs to be carried out later is the collection of "emotions", and virtual reality games are the best way to collect "emotions".

Of course, Leon can pull anyone in the world into the virtual reality world anytime, anywhere, but that doesn't mean Leon can collect their "emotions".

Because the alien's request is "voluntary", the person must voluntarily agree to be collected for "emotions".

Just like Gao Daqiang and Zhao Gongzi before, although they are diligent and inquisitive, serious in class, and have a lot of touching emotions, even if these "emotions" are collected, they are not counted.

Because they don't want to go to class, they don't want to have these emotions, and it's completely against their wishes.

But imagine that an ordinary person is sleeping well at home, and suddenly he is pulled into a mysterious space consciously, telling him that as long as he agrees to be collected emotions, he can enter the virtual reality game world to play, and how many people will choose to agree?

Anyone who is a little wary will resist these phenomena of unknown origin and unexplained.

Even if you carefully sift through and find 1 million fools who clicked to agree, what if the aliens raise the bar and have to collect 100 million emotions for the next mission? It's hard to find a fool with 100 million.

Therefore, to be on the safe side, to prevent any moths from the follow-up missions of the aliens, under the guise of a virtual reality game helmet and the terms of service before the game starts, let the virtual reality game appear in a way that players can understand, so that they can willingly enter the game and accept the collection of "emotions", which is the best policy.

Of course, the launch of virtual reality headsets and the release of virtual reality games will also attract the attention and covetousness of many people, and Li Ang already has some preliminary plans for these problems.

And what he's doing now is some of the preparatory work before the virtual reality game.

As a cross-era game mode, virtual reality games will naturally face problems in all aspects, and its improvement is equally important.

For example, the first question is whether it is better for the player to fall asleep or awake during a virtual reality game.

Of course, as we all know, it is better to sleep well, play a game for one night, and the next day will not affect your study and work, and still feel like you are full of sleep, which is the real virtual reality game that everyone expects.

But sleep is very important for humans, in the state of sleep, human brain activity will be significantly reduced, and the brain metabolism will only start when sleep.

When entering a virtual reality game and playing, players will inevitably enter a wake-up state to activate their brains.

There is a contradiction between the two.

After many more experiments, Leon finally found a suitable solution.

One of the most important reasons why humans want to sleep is the metabolism of the brain.

Metabolism is the process of renewing matter and energy in living organisms.

For example, the usual urine, detoxification, and perspiration are the most intuitive, and the detoxification of the kidneys and liver and the immunity of the spleen and lymphatic are not intuitive, and these internal organs are constantly flowing through the blood to carry out the body's metabolic work.

The same is true of the brain, which is a major energy consumer in the human body, and countless amounts of blood come to the brain with oxygen and nutrients all the time to supply it.

As the brain works for a long time, it will inevitably produce a lot of junk protein and biological waste, and as soon as these "garbage" accumulate, the work efficiency of neurons will begin to decline, and people will feel tired and want to sleep.

In order to ensure the continuous functioning of the brain, a sewage system is needed to carry out metabolism and expel these "garbage".

However, the human brain is the spinal cord and does not have a lymphatic system, so it cannot be directly injected into the lymphatic system and then enter the liver and other organs for processing.

The human brain uses another system, called the glial lymphatic system, during human sleep, the glial lymphatic system will follow the spinal fluid into the brain, directly contact the brain tissue, absorb all kinds of "garbage", and then transport them out of the brain, and connect with ordinary lymphatic tissue, and finally through the lymphatic system to the liver for detoxification.

However, the work of the glial lymphatic system is closely related to the flow of spinal fluid, and only when the flow of spinal fluid is large enough can it smoothly contact and cover the brain tissue and carry out the work.

The flow of spinal fluid is in turn related to the vascular space of the brain.

It is only while sleeping that the gaps between the blood vessels in the human brain become larger, making way enough for the spinal fluid flow to increase and the glial lymphatic system to work smoothly.

If the brain is active vigorously and the demand for nutrients rises, the blood vessels in the brain will expand, the gap between the blood vessels will shrink, the spinal fluid will not flow, the glial lymphatic system will stop working, and the "garbage" will naturally not be discharged.

Faced with such a dilemma, Leon's method was simple and crude.

When the player is sleeping, the [Proton Computer] directly takes over the supply of brain energy: directly draws the zero point energy of the vacuum and generates bioelectricity to supply the neuronal cells!

The blood vessels no longer need to transport nutrients on a large scale, and they are still in a state of contraction, even a little more constricted than before, to ensure the flow of spinal fluid and the smooth operation of the glial lymphatic system.

This ensures that even if the player is playing the game hard while sleeping, he can still study and work as if he has half slept the next day!

Then there is the important issue of player safety.

As we all know, when people are sleeping, they also have a certain sense of the surrounding situation, for example, if someone opens the door and comes in, if the movement is loud, the person will wake up.

But if the player enters the virtual reality game and immerses himself in the game, it will definitely not feel the outside world.

So what if there's a thief or something burglary, not to mention stealing something, but also giving the player up, and finally the player ends the game and takes off the helmet, isn't it confused?

There is also the player's own physical condition, in case there is any illness on the body, such as eating a bad stomach, and as a result, after playing all night, I woke up and found that I had pulled a bed, wouldn't it be a two-faced bewilderment?

There are also cold and hot feelings in the outside world, such as turning on the electric blanket and forgetting to turn it off, but being baked overnight, or the temperature of the air conditioner is low, and the result is frozen overnight, and finally a serious illness, isn't it a three-faced bewilderment?

Therefore, an unexpected observation system is a must, whether there is something strange in the outside world, or something is wrong with the player's body, this system will report to the player at the first time, and hand it over to them to decide to deal with it, which is really serious, and will directly cut off the link, so that the player can sober up and solve it, and even help the player dial 110.

In addition to the real problems of players, the virtual game itself also has certain problems that need to be solved.

Theoretically speaking, with the ability of third-order artificial intelligence lifeforms, it is completely possible to simulate a virtual world that is the same as reality.

To put it simply, what players can do in reality, can also do in the virtual world, and even do things that they can't do in reality, what they can feel in reality, can also feel in the virtual world, and even feel more.

But the virtual world is a virtual world after all, and there must be some differences from the real world.

One of the most important differences is the protection against pain.

The vast majority of people are able to feel pain, and pain is also one of the most important senses for human beings to perceive the outside world and perceive themselves.

There are also many kinds of pain, for example, when you are punched or cut by a knife, the pain you feel is completely different.

Depending on how you feel about pain, it's easy to know how you're hurting.

For example, if someone is slashed on the arm, some of them have just broken the skin, and it does not affect the movement; Some of the wounds are relatively large, and they may not be able to exert much strength; Some of them hurt their bones, and I'm afraid that this arm will not be useful for a long time......

However, depending on the will, the degree of tolerance of human beings to pain is also different, and when the pain reaches their limit, their body will automatically trigger emergency measures, in order to prevent greater mental damage, shock coma.

But even if the person is in a coma and shock, the huge amount of pain can still damage the person's spirit.

And in virtual reality games, it is inevitable to fight and be injured, if it is all according to the real thing, wouldn't there be countless people in shock every day?

Therefore, it is also very important to protect the sense of pain, according to different people, different willpower tolerance, to provide protection for all kinds of pain.

This protection does not affect their judgment of their own injuries, which is very difficult.

But fortunately, Li Ang has just found two good students, and collected a lot of precious data from them, which can be regarded as perfecting the whole set of pain and fear protection system.

Moreover, this system Li Ang does not intend to hand over to the player to set it up by himself, because the player can't know himself well, in case someone is stupid, watches the online game, and learns that the protagonist in it adjusts the pain to 100%, but he can't bear it, and he goes into shock, and he suffers mental damage, isn't it troublesome?

Of course, there are some other problems that Li Ang is also steadily solving one by one, so I won't introduce them here.
