Chapter 559 Methods to Cross Firewalls
Koushiro crouched down, his fingertips gently touching the broken edge of the stone platform, and began to recall the information that Elder Gennai had given him.

The structure of this world can be divided into three layers.

At the very top is the real world they live in, made up of matter.

The middle layer is an intangible and formless network world that exists based on human technology.

They are now in a digital world with an independent ecosystem, located in another phase of spacetime.

To prevent the digital world from expanding endlessly due to information from human networks, the world's administrators set up firewalls.

Later, in order to deal with the threat of the Apocalymon, the administrators reinforced the firewall, completely severing the connection between the human world and the digital world.

This door to the vampire castle clearly exploits a vulnerability in the firewall...

But now that road is blocked. The good news is, there's more than one way to get back.

Another image flashed through Koushiro's mind.

In the final battle against Etemon, Taichi's courage erupted, and MetalGreymon's attack caused a distortion in spacetime, bringing Taichi back to the real world.

In other words, it is possible to forcibly bypass the firewall as long as certain conditions are met.

However, this method is not very stable, and a more stable and controllable method must be found.

This will naturally take some time, but the good news is that there is a time difference between the digital world and the real world.

Although Myotismon seized the initiative, its lead was quite limited.

With that thought in mind, Koushiro stopped lingering.

He took one last look at the ruins, then turned and quickly left with the beetle beast.

Using the positioning system of the Etemon Network Hub, Koushiro located Taichi and the others.

He instructed the Kabuterimon to adjust its direction and fly at full speed toward the area where the light spots were converging.

Two days later, a vibrant forest appeared below.

In a clearing in the woods, Koushiro encountered his companions who were undergoing some kind of peculiar training.

A short, pink doll-like Digimon with a pair of wings on its back is holding a small wooden stick and solemnly directing Tai and the others to perform activities such as meditation and waterfall training.

It's a fairy beast.

"Photon Lang!"

Taiyi, with his sharp eyes, was the first to spot him. He immediately rushed out from under the waterfall, ignoring his soaking wet clothes, and anxiously asked,

"So? Did you find that bastard's castle?!"

"found it,"

Koushiro jumped off Kabuterimon's back and nodded.
"But it was too late..."

Then, Koushiro revealed all his discoveries in the Vampire Beast's castle, along with his analysis.

When they heard that the vampire beast had gone to the human world and destroyed the only passage, everyone's faces darkened.

"Then...what should we do?"

Meimei panicked a little, "Can't we go back?"

“Jia’er…”

Taiyi clenched his fists tightly and gritted his teeth.

"Although the situation is urgent, it is not yet hopeless."

Upon seeing this, Koushiro spoke up and explained the difference in the flow of time between the Digital World and the Real World.

Upon hearing this news, everyone breathed a slight sigh of relief.

"So your next task is still to evolve your Digimon. I will find a way to return to the real world..." Koushiro looked at everyone and their partner Digimon, who also looked solemn, and said.

After settling everyone in, Koushiro found a place where he could connect to the network set up by Etemon and set up his equipment.

Through the previously established encrypted channel, he successfully contacted Hyunnae, who was on the other side of the world.

When Gennai learned from Koushiro on the other side of the screen that Myotismon had breached the Firewall and entered the human world, his usually composed expression showed a dramatic change for the first time.

"This is too dangerous! A Digimon like Myotismon would cause unimaginable disaster in the unrestricted human world!"

Gennai's voice even changed slightly. Digimon can be affected by human emotions; that's what happened to Koromon a few years ago.

Despite being an ancient species that is difficult to evolve, it evolved from the juvenile stage to the mature stage in less than a day.

I don't even want to think about what would happen if it were a Perfect-level Digimon like Myotismon...

"So I need help, I need a way to bypass the firewall."

If it's like a firewall in the real world, then theoretically there must be protocols that can be bypassed.

Koushiro went straight to the point and asked the question.

"Your idea is correct..."

Gennai pondered for a moment, seemingly retrieving some information.

"The method is similar to what you in the human world call 'circumventing the Great Firewall,' which involves establishing a virtual private network channel to deceive the rules of the firewall and thus achieve cross-border data transmission."

But this requires a 'server' located in the real world as an anchor point for receiving and relaying data..."

"I have this."

Koushiro interrupted him and spoke up.

Over the next few days, Elder Gennai sent over fragmented documents about the underlying architecture of the firewall. With his amazing talent, Koushiro translated and deciphered the obscure ancient digital text line by line, converting it into an executable program.

A complex stream of instructions scrolled wildly across the screen.

Finally, one morning a few days later, the moment the last line of code was entered and the Enter key was pressed, the answer was found.

A line of green characters quietly lit up on the black console screen.

【CONNECTION ESTABLISHED: KOSHIRO-PRIVATE-SVR-01】

"Connection... Successful."

"I'm tired," Koushiro said softly.

He successfully connected to his private server at his home in Tokyo.

This means that he has opened the data channel to the real world.

However, before he could even breathe a sigh of relief, a sudden change occurred.

The complex code he had just finished writing to bypass the firewall seemed to come alive, writhing and twisting restlessly on the screen. They were no longer static characters, but had transformed into glowing, flowing threads.

These threads attract, intertwine, and converge, as if following some ancient law from a deeper level of the world. They break free from the framework of code and gather at the center of the screen.

Immediately afterwards, a cluster of crimson flames ignited without warning.

The flames quickly outlined and took shape, eventually coalescing into a mysterious and ancient icon that looks like the Chinese character for fire.

Following the flames appeared a half-human figure pattern interwoven with red and gold.

"Um?!!"

Koushiro stared blankly at the icon, momentarily at a loss for what to do.

Isn't this the pattern of Vulcan from the Ten Warriors in Generation IV?
