In the dark and treacherous cyberspace, the blurry light images are the aurora of the North and South Pole Sky Dome, and the particles of data light and shadow construct a virtual but real picture.

Whenever he entered the cyberspace, Lin Mo would feel like he had stepped into a place like the legendary Hell and the Underworld, with no one to accompany him, walking alone in such a rather gloomy place, and indeed from the bottom of his heart he felt a sense of panic when he walked alone at night.

However, it is said that this was not the case in cyberspace from the past few decades.

At that time, cyberspace was still the era of the Internet, and even an ordinary person could access the online world at will, rather than only professional hackers dared to step into it like now.

Moreover, those ordinary people who are not professional hackers will also have another name when they enter the cyberspace - cyber walkers.

If the cyberspace of the past is still the dark and treacherous scene it is today, then it will be impossible to attract ordinary people to "consciously surf the Internet".

Therefore, some of the current miscellaneous books about the Internet describe what the cyberspace was like in the old era.

Anyway, according to Lin Mo's reading comprehension of those miscellaneous books, the previous cyberspace was completely people's second world.

Some network areas can even be compared to the real world in terms of realism, and some specialized network companies can also create mythical "Yin Dianyuan"-like play areas.

But no matter how glorious the era is, it will eventually pass.

The cyberspace is now in a state of depression, and no one else will set foot here except professional hackers.

It is precisely because there is no flow of people and no profit points that elements such as "realism" and "playability" that attract ordinary people to play cyberspace are naturally completely gone.

With a hint of regret, in a few seconds, Lin Mo teleported to the "edge" of today's online world.

What catches your eye is an endless dark red.

The dark red lines are arranged vertically, one by one, like a "wall" of wooden stakes, and through the gaps between the lines, you can even glimpse the light and shadow outside the wall.

This is the "boundary wall" of the existing controllable online world - the [black wall].

"The first time I came here, I didn't expect the scene to be much different from the one in the game."

Lin Mo couldn't help but sigh with emotion, and his gaze wandered around this boundless "wall".

At the same time, some information about the "black wall" also subconsciously came to his mind......

After the famous [Data Crash] virus released by Bartmos, Cyber Monitor, as the leading European cyber security organization, took on the task of repairing the online world.

A few years later, they simply failed, and they failed miserably in the confrontation with dangerous enemies such as roaming AI and malicious attack programs, and they simply could not reclaim those "lost cyber ground".

It didn't take long for the "black wall" to appear without warning, and no one knows how cyber surveillance managed to build it in a single day, although they supposedly seemed to have reached some sort of agreement with the AI.

And those hacker masters who are still stuck in the old network area and have not had time to return have also become victims because of the sudden appearance of the black wall, unable to safely disconnect and return to the real world.

The completion of the "black wall" has completely blocked those dangerous factors such as flowing AI and malicious puppet programs from the network area controlled by humans, and because of this achievement, network surveillance has also become an international organization sponsored by all companies from a single enterprise.

......

In so much information, Lin Mo couldn't explore what the network surveillance had done, but he still paid attention to a more important information point

- The black wall appeared without warning!

In the huge online world, any data file and data program can be traced, and what can appear without warning is often only a "puppet program" hidden in the body of a network hacker.

And some of the more advanced puppet programs, hackers can also choose to add "pseudo-intelligent" code to them, making them a unique individual.

This is also the origin of those "malicious programs" on the old network, although due to the limitations of their own programs, they cannot become truly independent AI, but they still have a certain intelligence, just like a spiritual weapon in fantasy, full of malice towards human beings.

In a sense, puppets loaded with intelligent code can also be called artificial intelligence, but they still have certain flaws compared to real independent AI life.

"So, could the Black Wall be a puppet too?"

Looking at the black wall that emitted a conspicuous light, Lin Mo couldn't help but ask himself.

"But if it's really a puppet, who in the world has the ability to build a puppet program of this scale in an instant?"

For a long time, Lin Mo, who still couldn't find an answer, could only sigh helplessly, and his figure flickered a few times, and he had already come to the front of the black wall.

Gradually approaching the dark red lines, Lin Mo could feel that the black wall was "repelling" his approach, and it seemed that he didn't want him to pass through.

However, he also found that this "repulsion" was not strong.

With his current ability, he can easily penetrate the black wall to the "Old Net" area...... This also seems to show that the biggest role of the black wall is not to hinder humans, but to block AI.

【Puppet-Parser】

Lin Mo's hands emitted a faint light, and he pressed his hands on the thin red lines seriously, and his hands gradually merged into the data wall.

A white glimmer of light gradually spread from his palm, like ink dripping into the clear water, and the white light covered the red light and gradually eroded the wall.

After a while, a large amount of data code poured into Lin Mo's mind, and he clearly perceived the essence of the "black wall", and his powerful computing power allowed him to easily understand this information!

He understood everything!

In the end, the white light diffused to a range of tens of meters, and after sensing that the follow-up analysis had little effect, Lin Mo stopped his movements.

He looked at the black wall, and his face showed an expression that was indeed so.

The result did not surprise him!

The essence of the black wall is no different from that of a puppet, but it is equipped with a simple intelligent program, which has become the largest "artificial intelligence", which can distinguish dangerous things such as flowing AI and malicious programs, and block them strongly.

And in a certain program, the black wall also has a self-healing function!

Thinking of this, Lin Mo couldn't help but continue to look at this boundless wall, and muttered to himself:

"Such a huge puppet, such a magnificent spectacle, the greatest reliance of network surveillance... Who has the ability to build it in an instant? ”

There is no answer to this question.

Lin Mo sighed, and had no choice but to put his mind on the program code he had just parsed.

"Thanks to Rebecca's inspiration, this trip wasn't in vain."

He chuckled and waved his hand, summoning a small house building in the cyberspace.

The house is only the size of a palm, and the details have not been beautified, and it is very similar in appearance to the building that Xu Shiming pulled in last time.

It's just that the walls of the building have completely become the same structure as the black walls.

【Puppet - Labyrinth - Black Wall Upgrade】

After the analysis just now, he doesn't need to make any changes, he only needs to add the code used to block AI inside the "black wall" to the puppet in a special way, so that the puppet can perform a specific function.

Seeing that he had gained a lot this time, Lin Mo did not continue to stay in the cyberspace, and his mind moved slightly and he went offline from the cyberspace.

......

In the warehouse, as soon as he got up from the hacker chair, Lin Mo couldn't wait to take out the simulator.

This time, with the upgraded version of the black wall puppet, he doesn't believe in the final result, and he will be escaped by AI Xu Shiming!
