The corridors and rooms that had been silent for seven centuries were revitalized.

As the core control area of the "ridge" became wider and wider, more and more flickering runes and energy veins began to appear on the walls on both sides, and the ornamental columns with a strong elven style were arranged on both sides of the wide space in front of them, at the end of this wide corridor, all the internal passages of the "ridge" converged together, forming a six-pointed star-shaped radial hall, and a cylindrical "room" was located in the center of the hall, which was surrounded by countless pipes, Metal beams and runic pillars are guarded.

This is the control center of the Sentinel Tower, the place where the demonic mind is housed - in Gawain's view, the central computer room where the artificial intelligence is located.

The entrance to the computer room was closed, and two beams of light that shone obliquely from high in the sky illuminated a small open space in front of the entrance, Amber looked up and looked up the outer wall of the cylindrical room, and saw a hazy layer of light and shadow floating on top of it, and huge curtains hung down from between the light and shadows, and those curtains depicted the emblems of the Silver Empire and the human nations, some of which had been badly decayed by the years, and only the tattered strips of cloth hung quietly in the air, as if ...... Shroud.

Amber blinked, and for a moment she felt like she saw something in the curtains—some gray shadows, wriggling and rolling, like silt growing and rolling in those dark corners, and a faint figure emerging from the growing shadows, spying on the uninvited guest who had suddenly broken in.

However, in the next second, these things vanished like illusions.

"What's wrong?" Gawain's voice woke Amber out of her stupe, "What have you been staring at?" ”

"No...... I guess I've misunderstood," Amber blinked, rubbing her eyes, "what's on there?" It was as if there was a layer of mist floating in it. ”

"That's the magic top, and above the top of the cloud is the outer space. The canopy of this pedestal is actually open, and the mana focuser draws powerful energy from the leylines and mana foci to create a powerful mana cloud top in the open area of the pedestal, supplying the 'stone tablet' on the one hand, and maintaining the protection system of the entire pedestal on the other," the elven magister Banner explained, "Once the cloud top is extinguished, the Sentinel Tower is finished, so it has never stopped for seven centuries. ”

Amber groaned in understanding, and Banner walked to the entrance to the cylindrical room, once again injecting magic into the elven reliefs on the entrance.

Thankfully, this time the door didn't jam — he didn't have to pull out his elbow wrench again.

The room where the demon's mind was housed opened, and the Iron Ranger warriors, led by Thorderling, guarded the entrance to the room, and Gawain stepped inside, carrying Amber.

A magnificent blue float filled the cylindrical room, and Amber couldn't help but exclaim softly as soon as she entered the door—she saw that the entire floor of this room was made of the purest obsidian, and on the surface of the obsidian, which was as black as night, was carved with extremely intricate rune patterns, which emitted a light blue shimmer and intertwined with the blue crystals embedded in the walls of the room, and in the center of the room, a black cube about a meter long and wide was floating silently in the anti-gravity field.

The surface of the black cube has straight blue lines, the overall material seems to be some kind of metal, and faint runes float on each plane separated by blue lines, looking mysterious and mysterious.

As if sensing someone approaching, the cube rang out with a pleasant chirp, then it spun, and the blue lines split it into countless large and small squares, and the metal structures reassembled in a dizzying way like a Rubik's cube, and a slightly dull synthesized voice rang out in the room: "Sensing the approaching organism...... Identifying ...... Builder Permissions, Authorized Visitors, Commanders...... Error, the commander authority does not follow the logic, re-certify, the commander ...... Error, this commander authority is not logical, recertification ......"

The voice from the cube became more and more confused, and Gawain finally couldn't help but cough softly: "Ahem, I'm resurrected." ”

“…… Voice Authentication, Pass, Organism Magic Pattern Feature, Pass, Human, Resurrection Individual, Incomprehensible, Incredible...... Ignore bugs, fix databases, reload Commander privileges. Gawain Cecil, Human, Leader, it's a pleasure to see you again, and the Sentinels salute you—you've lived so long. ”

The cube's voice became smoother, and it continued to reassemble itself as quickly as a Rubik's cube, "The system has been running for 706 years, 22 days, 7 hours, 13 minutes, 12 seconds, and this is the first time that a visitor has interacted during operation, what happened?" ”

Banner waved his hand in front of the cube and said after casting some kind of special control spell, "Sentinel, keep running, let's check the system." ”

"Sentinel understands, keep running."

There was a low buzz inside the cube, and then its constantly changing blocks quickly returned to their original positions, and the entire cube became full and neat again, and continued to float peacefully in the anti-gravity field, while Banner came to a silver-white alloy pillar not far from the cube, activated the ancient magic array, and began to check the operation of this "demon mind".

Amber's eyes widened, and only then did she exclaim, "Wow, is this the 'Tower Spirit' of the Sentinel Tower?!" ”

"Taling is the name of the artificial mind of the mage tower built by humans, and the name of the elf is 'Demon Spirit Mind', the two have different names and different technologies," Sonia explained, and then looked at Amber with a blank face with some curiosity, "Little girl, didn't your father tell you about the elven realm?" ”

She judged from the shape of Amber's ears that the half-race girl's father was supposed to be an elf.

"I don't even know who my real parents are," Amber said, shaking her head, "I was adopted by two humans......

"Ah, I'm sorry," Sonia was a little embarrassed, and her eyes couldn't help but soften a little when she looked at Amber, "It turns out that humans raised you, no wonder you know so little about elf things...... Are your adoptive parents still around? ”

Amber's pointed ears twitched slightly: "My adoptive father is gone, but another adoptive father is still there...... Well, yes, both humans who adopted me were men. ”

Sonia was stunned, her expression slightly sluggish: "It turns out that the atmosphere of human beings has been so open in the past seven hundred years......

Gao Wen was still listening to the excitement next to him, and at this time he immediately couldn't hold back: "Ahem, I think you may have misunderstood, the one who adopted Amber was ......"

However, Sonia no longer seemed to be able to listen to Gawain's follow-up, and the elven mother, who still looked very young, had fallen into deep anxiety and muttered to herself, "This is not going to work...... Sölderlin in this environment...... He can't find a girl he likes because of this......"

Gawain Amber: "......"

It seemed that the elven mother had a serious misunderstanding of Amber's two adoptive fathers, but before Gawain could continue to explain anything, Banner not far away suddenly broke the silence: "High courier, Duke Cecil, there is no fault record here. ”

The elven magister raised his head as he spoke, and only then did he notice the slightly awkward atmosphere of the scene: "Ah, what are you talking about?" ”

Everyone's attention immediately returned to business, and Gawain hurriedly waved his hand: "No, it's nothing - you said that there is no fault record here?" ”

"Yes, the log shows that the Sentinel Tower has been working normally," Banner turned to the side, and behind him, a large number of illusion projections were emerging around the silver-white alloy pillars, and the floating elven text on the projection showed the operation records of the Sentinel Tower in the past two or three years, "No alarm information was found for the first overload, only the last overload." ”

Sonia couldn't help but frown, she looked at the metal cube in the center of the room, "Sentinel, ask." ”

The cube quickly responded: "Sentinel on standby." ”

"Did the tower overload in a period of two to four years ago?"

"Search...... No results. The tower was not overloaded during this time period. ”

"Everything was normal during this time? Nothing glitching? ”

"Everything was fine with the tower during that time period without any breakdowns."

The atmosphere at the scene became serious and silent, and several people subconsciously exchanged glances.

There is something wrong with this AI's reply.

Sonia has come to a clear conclusion - the first overload failure occurred was this Sentinel Tower located in the southeast of Ansu!! It malfunctioned about three years ago before Gawain unveiled the coffin, and it was this glitch that led to the destruction of the old Cecil Territory by the wandering aberrations.

However, the Demon Spirit Mind, which had been running for seven centuries without downtime, said...... It simply didn't know about this failure!

The Sentinel Tower didn't send any malfunction reports back to the Silver Empire's general control center!

Gawain frowned and looked at Banner and asked in a low voice, "Is the demonic mind itself functioning properly?" ”

"Everything is normal, I've checked all of its mental nodes, and there's no sign of tampering or self-reorganization," Banner said with a serious face, "In this case, the Sentinels will never mutiny." ”

"Then the problem is somewhere else," Gawain took a deep breath, "If even the Sentinels lose full control of the Tower, we're in big trouble." ”

That's one of the reasons why Gawain insisted on coming to inspect the Sentinel Towers - these towers, there really is a problem!

However, as the controlling core of the Sentinel Tower, the tower's demonic mind has no record of failure, which is precisely the most disturbing situation.

The fault occurs in the dead end of the system.

"What could be to block the Sentinel's perception and control of the Tower, or tamper with its recorded results without leaving a trace?" Gawain looked at the only expert on the scene, Magister Banner, "If the tower is overloaded, where will the alarm signal come from?" ”

"Theoretically, no alarm signal can bypass the sentinel's surveillance," Banner said immediately, "and it's the highest priority." ”

Sonya, Gawain, and Banner then discuss and analyze the sentinel's operating mechanism, trying to find potential vulnerabilities in the system, but Amber, who is standing next to her, doesn't understand these technical things at all, and the half-elf lady begins to wander into the world.

She blinked, looking around the room filled with soft blue light and magical energy.

Once again, she seemed to hallucinate—

In a corner of the room, near a runic focal point filled with magical power, a black crack suddenly appeared in the air, and a shadow spread out of the crack, growing and shaking in the air, Amber blinked, but the shadow did not disappear immediately, but a hazy figure emerged from it.

It was a figure with no features or physical details, as if bound by some loose strip of cloth, and it shook twice between the black cracks, leaning out half of its body, and then beckoned to Amber.

Amber whispered in surprise, "Huh? ”

The figure raised his hand, pointed straight up, and pointed hard, before fading away.

"What's wrong?" Gawain noticed Amber's wandering mind again, and when he noticed that the other party was staring at some empty corner, he immediately exclaimed, "What are you looking at?" ”

"I think I see a ...... Shadow dwellers? Amber blinked, and when she woke up, she found that there was no longer the rift and the figure in front of her, "Strange, how can there be a rift here...... I can't even feel it......"

Then she shook her head and looked up curiously: "Hey, Auntie, is there anything on it?" ”

"Auntie...... Sonya's expression froze for a moment, but she still glanced up, "The rooftop." Beyond that, it's the magic cloud top......"

At this moment, Banner suddenly reacted: "Wait, it's not just Magic Cloud Peak!" It's a stone monument!! ”
