496 glanced at him, the corners of his mouth raised slightly: "Don't be too excited. Discovering it is a good thing, but the danger of this thing is probably beyond your imagination."

"How dangerous is it?" Xiang Fan leaned closer to the screen curiously, like a child listening to a story. "Master, can this thing blow up a mecha?"

496 was amused by his naiveté and shook his head, saying, "It's much more serious than blowing up the mecha. Vulnerabilities and backdoors, these aren't just little things you can play with."

He patiently pointed at the rune chain on the light screen. "A loophole is an unintentional flaw in the design of the psychic network. With a rune chain like this, whose logic is not closed, the flow of psychic energy bypasses verification. It's like someone opened a small hole in a tall building, letting wind and rain in and out freely. If someone exploited this loophole, at best, the system would be paralyzed, and at worst, the entire network would collapse."

"What about the back door?" Xiang Fan was already listening with great interest, his chin supported by his hands, a look of anticipation on his face.

496 tapped his finger, and a series of permission control options suddenly popped up on the psychic model. He raised an eyebrow, his tone meaningful, "A backdoor is a secret entrance intentionally left by the designer. It's like a spare key, bypassing permissions and directly controlling the core of the psychic network. In an emergency, it can save lives, but if it falls into the wrong hands..."

Xiang Fan took a deep breath and said, "Isn't that... the vital point of the psychic network?"

"Clever." 496 nodded calmly. "Designing a backdoor is a technical necessity, but the price is exposing the core control of the system. If exploited by someone with ulterior motives, the psychic network will completely become their tool."

Xiang Fan stroked his chin and began to think, "So, could I use this backdoor... to secretly tamper with my opponent's mecha system? For example, have them suddenly type 'I love Zero' during battle?"

496's mouth twitched, and he couldn't help but slap the table. "What's wrong with your brain circuit? Such a great discovery, and you've turned it into a joke?"

"Master, I was just kidding!" Xiang Fan scratched his head awkwardly. "But this thing is really useful. Why did the designer leave such a backdoor?"

496 narrowed his eyes and said in a deep voice, "Backdoors are sometimes a necessary evil. They can quickly fix problems when the system goes out of control, but technology is always a double-edged sword. Designers leave them in for security, but they can't avoid the risk of their abuse."

Xiang Fan nodded repeatedly, but his face turned pale. "Then... if someone specializes in studying these things, would it be possible..."

"Yes," 496 interrupted him, his voice as cold as ice. "If these vulnerabilities and backdoors are maliciously exploited, the entire psychic network will be paralyzed, potentially causing immeasurable damage. This isn't just a technical issue; it's a strategic threat."

"What should we do then?" Xiang Fan gritted his teeth, a trace of anxiety flashing in his eyes. "Master, should we report this to the Spirit Realm Battlefield officials immediately?"

"Report it?" 496 sneered, his tone tinged with a hint of amusement. "Do you think the designers of the Spirit Realm battlefield are unaware of the existence of these things? The significance of these backdoors is far more complex than you imagine."

"Then let's..." Xiang Fan opened his mouth, but was interrupted by 496 raising his hand.

"Zero, this isn't something to be anxious about." 496's eyes grew deep. He stood up, hands behind his back, and paced back and forth, his tone calm and resolute. "The existence of vulnerabilities and backdoors reveals that the design of the psionic network is not perfect. This may be a technological dividing line in the future."

Xiang Fan was a little confused: "Technical dividing line?"

496 turned to look at him on the screen, his eyes piercing. "Yes. The security of the psychic network may become one of the most important research directions in the future. This is not only to prevent accidents, but also to protect the infrastructure that the monks rely on from being threatened."

Xiang Fan's eyes gradually became firm. "Master, I understand. I will continue to study this knowledge and find out the loopholes and backdoors."

496 nodded with satisfaction. "Very good. But remember, technology is a double-edged sword. If used improperly, it can hurt both yourself and others."

"Yes, I will be careful!" Xiang Fan clenched his fists, with an unprecedented determination on his face.

"Then keep working on it, little one." 496 smiled and closed the communication. Silence returned to the Spirit Realm Laboratory, but a look of deep thought appeared in his eyes.

After Xiang Fan logged out, he sat at his small workbench, staring at the rune chain on the screen and muttering to himself, "Security issues... Looks like I've really messed up this time. But perhaps this is an opportunity."

He shook his head, opened his notebook, and wrote a line: "Security Research - From Vulnerabilities to Backdoors." In his mind, countless possibilities for the future of the psychic network emerged faintly.
