"Meow?"
The robotic sphere (little white cat) tilted its head, looking up at its owner.
It didn't understand what had happened.
Jiang Lin walked to the desk and gestured for the robotic sphere to come over as well.
Then he took out the small black brick and tapped the tabletop, "A mobile phone made according to the human model?"
The little white cat squatted in front of the desk and nodded:
"But its functions are limited, and currently, only phones of the same model can be powered on."
Jiang Lin pointed to the metal objects on the bookshelves and beams inside the hall, "What are those...?"
The little white cat: "Small, movable, and detachable signal towers."
It stood up on its hind legs, gesturing with its two paws, and explained:
"Although there seem to be many parts, they are actually only about the size of your three fists when assembled.
They are very convenient to carry.
Within their radiation range, you can connect to a phone anywhere."
Jiang Lin: "What is the range?"
The little white cat: "Currently, only a hundred meters in radius."
After all, materials are limited.
Just these few items have already emptied its inventory.
"Currently?"
Jiang Lin's expression was unreadable, "Can the range be expanded?"
The little white cat thought seriously, furrowing its brow in a human-like manner,
"Yes. But how much larger it can be... we'll only know after testing."
Although it was successful for now, it was just a mini version.
If a larger version were to be made, there would definitely be more problems.
Just like...
Just like how people build bridges and houses.
Making a small model versus making a physical, oversized version involves not just material issues.
There's also whether it can be supported, whether it's waterproof and shockproof,
Whether it can remain stable under extremely strong winds...
In short, there are many problems.
Considering all these factors requires a lot of computation and continuous experimentation.
Jiang Lin pondered for a moment, "If the signal tower's range were to be expanded to cover the entire Underworld, what confidence do you have?"
The entire Underworld?!
This robotic sphere had never considered that before.
It initially...
Was just thinking, well, being doted on, earning pocket money.
But since the owner brought it up, it had to think carefully.
"Master, please wait."
The little white cat in front of him became solemn.
Then it took out a large stack of white paper and various metal props.
And spread them out on the ground.
It began to perform calculations on the spot.
In a short while, several pages of calculated numbers were drawn.
Jiang Lin got up to take a look,
And then...
He couldn't understand it.
He hadn't even fully deciphered the "[Publicly Available Information on Unresolved Mysteries of the Underworld]" he brought back from the West Hall.
Wait,
Jiang Lin suddenly thought of something.
He had been reading these materials in the hall before.
Did the robotic sphere see them?
And then tried to tinker with them?
...
Jiang Lin stood to the side,
Seeing that the robotic sphere was very focused, he didn't speak again.
He maintained silence.
He also sat down and flipped through the materials he brought back from the West Hall.
The development process of the internet in the human world can be roughly divided into three steps.
One: Collect materials and manufacture the network.
And the electronic products used with the network.
Two: Create firewalls to protect user safety.
Three: Create more advanced firewalls, even reverse pursuit, self-destructing wipes, etc.
To prevent high-level individuals like hackers and black hats from breaking in and stealing information.
If the Underworld were to develop a network,
It would likely follow a similar process.
First, find suitable materials in the Underworld for manufacturing signal towers and electronic products.
Second, create firewalls.
The existence of a firewall is akin to installing a gate and locking it at your doorstep.
Preventing ordinary people from entering.
Protecting oneself and the things at home.
But the difficulty lies precisely here.
In the Underworld,
Ghosts and spirits are basically energy forms with certain abilities.
For example, some ghosts can crawl along the network cables of the human internet...
Advanced ghosts possess powerful mental strength and perception.
Take Jiang Lin, for instance.
If he wished, with his perception activated,
He could observe everything from large ghosts to small ants around him.
Now, consider the function of a network.
It's for transmitting information.
Within the range of a signal tower, residents from all over the world can communicate in real-time, anytime, anywhere.
And information transmission... involves energy fluctuations, right?
Ordinary ghosts might not be able to detect it.
But for high-level ghost officers, it would be difficult not to notice.
If we were to visualize it,
It would be like countless energy lines zipping back and forth overhead.
Zipping past, and then zipping back.
With a strong presence.
Intercepting information, or perhaps, tracing these energy lines to find the ghost transmitting the information, doesn't seem difficult.
Information security is one matter,
For high-level ghost officers, having things zipping around overhead from time to time is also quite annoying.
If one were to describe it,
High-level ghost officers are similar to some network experts in the human world.
—With a computer in hand, you can roam the network world at will.
The human world can create more advanced firewalls, but the Underworld...
A firewall that can defend against high-level ghost officers...?
That's a bit difficult.
Most importantly, how can the transmission of signals avoid detection?
There must be special materials for this.
But they would also be very precious.
Once the network is deployed, covering vast distances.
A little bit won't be enough.
In summary,
The difficulty of developing a network in the Underworld is not just a little bit.
...
However, when Jiang Lin was communicating with the robotic sphere earlier,
He didn't detect any energy line fluctuations.
Even from "Number One's" perspective, the energy core inside the phone couldn't be seen through.
This was also what surprised Jiang Lin.
Although he felt that,
He hadn't yet fully unlocked all the functions of "Number One's" perspective.
If "Number One's"本体 were here, it should be able to see deeper things.
After all, "Number One" from that era,
Not only could it see through the structure of humans and demons,
But it could also analyze and customize cultivation methods suitable for humans and demons based on these images.
However,
Even if it could only defend against his current self, Jiang Lin felt that these two phones and this detachable signal tower were quite interesting.
After all, he was now not only a ghost officer at the Underworld Envoy realm but also possessed that gray energy.
Jiang Lin played with the black mobile phone,
The more he looked, the more he felt that the robotic sphere's invention this time was very feasible.
If the Underworld could truly install a network...
