The corridors and rooms, which had been silent for seven centuries, were reactivated.

As it gets closer to the core control area of ​​the base, the corridor inside the "ridge" becomes wider, and more and more flashing runes and energy veins begin to appear on the walls on both sides. The patterned columns with a strong elf-style style are arranged on both sides of the wide space ahead. At the end of this wide corridor, all the internal channels of the "ridge" converge together and form a hexagram-shaped radial hall, while a cylindrical "room" is located in the center of the hall, guarded by countless pipes, metal beams and rune pillars.

This is the control center of the Sentinel Tower. In Gao Wen's view, it is the central computer room where artificial intelligence is located.

The entrance of the computer room was closed tightly, and two beams of light tilted down from the sky illuminated a small open space in front of the entrance. Amber raised her head and looked up along the outer wall of the cylindrical room. She saw a layer of hazy light and shadow floating on its top, while a huge curtain drooped down from the light and shadow. The curtains depicted the emblems of the Silver Empire and human countries, some of which had been severely decayed by the erosion of time, leaving only the tattered strips of cloth hanging quietly in the sky, as if... a shroud.

Amber blinked, and for a moment, she felt that she saw something in the curtains, some dark shadows, wriggling and rolling, like mud, growing and rolling in those dark corners, and a faint figure emerged from the growing shadows, peeping at the uninvited guests who suddenly entered here.

However, the next second, these things disappeared like hallucinations.

"What's wrong?" Gao Wen's voice woke Amber from his stunned mind, "What are you staring at?"

"No... I should have read it wrong," Amber blinked and rubbed his eyes. "What's that? It seems like a layer of clouds are floating."

"That's the magic cloud top, and the outer space above the cloud top is the outer space. The ceiling of this pedestal is actually open. The magic focuser draws powerful energy from the earth veins and the magic focus to create a powerful magic cloud top in the open area of ​​the pedestal. On the one hand, it supplies a 'stele' and maintains the protection system of the entire pedestal," explained the elf magician Banner. "Once the cloud top is extinguished, the Sentinel Tower will be finished, so it has never stopped for seven centuries."

Amber said oh damn, and Banner came to the entrance of the cylindrical room and injected magic into the elf relief on the entrance again.

Fortunately, this time the door did not get stuck, he no longer had to take out his elbow wrench.

The room where the Demon Spirit's mind was opened, and the Iron Rangers warriors were guarding the entrance of the room under the leadership of Saldrin, while Gao Wen took a step and walked into it with Amber.

A magnificent blue floating light filled the cylindrical room. As soon as Amber entered the door, she couldn't help but exclaim softly. She saw that the entire floor of the room was made of the purest and flawless obsidian. On the surface of the obsidian as dark as night, it was carved with extremely fine and complex rune patterns. The runes emitted light blue light and reflected the blue crystals inlaid around the walls of the room. In the middle of the room, a black cube about one meter wide was floating quietly in the anti-gravity field.

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

It seemed that someone was approaching, and a pleasant sound rang out of the cube. Then it turned, and the blue lines divided it into countless blocks of large and small sizes. These metal structures were reorganized in a dazzling way like a magic cube. A slightly dull synthetic sound rang in the room: "Sensing the organism is approaching... In recognition... the construction engineer's authority, authorized visitors, commander... Error, the commander's authority is illogical, re-certified, commander... Error, the commander's authority is illogical, re-certified..."

The sound from the cube became more and more confused, and Gao Wen finally couldn't help but cough softly: "Cough cough, I'm resurrected."

"...Sound authentication, pass, organic magic pattern characteristics, pass, human, resurrected individuals, difficult to understand, incredible... Ignore errors, correct databases, and reload commander authority. Gowen Cecil, human, leader, is very happy to see you again, the sentry pays tribute to you. You have lived so long."

The sound of the cube became smooth. It continued to reorganize itself quickly like a Rubik's Cube, and continued to say: "The system has been running at 7:13:12 days. This is the first time that the visitor interaction has been conducted during the operation. What happened?"

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

"The sentry understands, keep running."

A low buzzing sound came from the cube, and then the blocks that constantly changed positions quickly returned to their original position. The entire cube became complete and neat again, and continued to float calmly in the anti-gravity field. 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 "magic mind".

Amber widened his eyes and exclaimed at this time: "Wow, is this the 'Tower Spirit' of Sentinel Tower?!"

"Ta Ling is the name of the artificial mind of the mage tower built by humans. The name of the elves is 'Demonic Mind'. The names of the two are different and the techniques are not universal," Sonia explained, and then looked at the confused Amber with some curiosity, "Little girl, hasn't your father ever told you about the Elf Kingdom?"

She judged from the shape of amber's ears that the father of this mixed-race girl should be an elf.

"I don't know who my biological parents are at all," Amber shook his head and said calmly, "I was adopted by two humans..."

"Ah, sorry," Sonya was a little embarrassed. Her eyes looked at Amber and couldn't help but feel a little soft. "It turns out that humans raised you. No wonder you know so little about elves... Are your adoptive parents still there?"

Amber's pointed ears shook slightly: "My adoptive father is gone, but the other adoptive father is still there... Well, yes, the two humans who adopted me are both men."

Sonia was stunned, her expression was a little dull: "So the human atmosphere has been so open for seven hundred years..."

Gao Wen was still listening to the fun, but he couldn't hold back at this time: "Ahem, I think you may be a little misunderstood. The one who adopted Amber is..."

However, Sonia seemed to be unable to listen to Gao Wen's follow-up words. The elf mother, who still looked very young, was already in deep anxiety and muttered alone: ​​"This is not possible... Solderin is in this environment... Could it be that he can't find the girl he likes because of this..."

Gao Wenamp; Amber: "…"

It seems that the elf mother had a serious misunderstanding about Amber's two adoptive fathers. However, before Gao Wen could continue to explain anything, Banner, not far away, suddenly broke his silence: "The high-level messenger, Duke Cecil, there is no record of the fault here."

The elf magician raised his head as he spoke, then noticed the awkward atmosphere in the scene: "Ah, what are you talking about?"

Everyone's attention immediately returned to the main business, Gao Wen quickly waved his hand: "No, there is nothing you said there is no fault record here?"

"Yes, the log shows that the Sentinel Tower has always been operating normally," Banner opened his body sideways, and behind him, a large number of illusion projections were emerging around the silver-white alloy pillars. The elf text that kept floating on the projection showed the operation records of the Sentinel Tower in the past two or three years. "The alarm information for the first overload was not found, only the last overload was found."

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

The cube quickly responded: "Sentinel stands for order."

“Has this tower overloaded during a time period two to four years ago?”

"The search...no results. The tower did not overload during this time period."

"Everything is OK during this time? Nothing is wrong?"

"All this tower is normal during this time period and no malfunctions have occurred."

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

There is a problem with this AI's answer.

Sonia has already brought a clear conclusion that the first overload failure was the Sentinel Tower located in southeastern Ansu! It was the fault that occurred about three years ago before Gauven lifted the coffin, and it was this fault that led to the destruction of the old Cecil's roaming out of the distortion.

However, the Demon Spirit Mind, which has been running for seven centuries without shutting down, said... it has no idea about this failure!

The Sentinel Tower also did not send any fault reports back to the General Control Center of the Silver Empire!

Gao Wen frowned and looked at Banner, and asked in a low voice: "Is the demon mind itself normal?"

"Everything is OK, I've checked all its mental nodes, without any signs of being tampered with or reorganized by itself," said Banner with a serious face. "In this case, the Sentinel will never be able to rebel."

"Then the problem lies somewhere else," Gao Wen took a deep breath. "If even the sentry loses complete control of the tower, then we will be in great trouble."

This is one of the reasons why Gao Wen insists on checking the Sentinel Tower these towers, there is really something wrong with them!

However, as the control core of the Sentinel Tower, the tower's demonic mind has no record of any faults, which is the most disturbing situation.

The failure occurs in the blind spots of the system.

"What can block the sentinel's perception and control of the tower, or tamper with its recording results without leaving any trace?" Gao Wen looked at the only expert on the scene, the magician Banner, "If the tower is overloaded, where will the alarm signal be emitted at the earliest?"

"In theory, no alarm signal can bypass the Sentinel's surveillance," Banner said immediately, "it has the highest priority."

Then Sonia, Gao Wen and Banner discussed and analyzed the operation mechanism of the Sentinel, trying to find potential loopholes in this system. However, Amber, who was standing next to him, could not understand these technical fields at all. The half-elf lady began to wander around the sky.

She blinked and looked around in the room filled with blue soft light and magical energy.

She seemed to have an illusion once again

In a corner of the room, near the rune focal point filled with magic power, a black crack suddenly appeared in the air, and a shadow spread out from the crack and grew and trembled in the air. Amber blinked, but the shadow did not disappear immediately, but a hazy figure appeared from it.

It was a figure without facial features and limb details. His whole body seemed to be bound by some loose cloth strip. He shook twice between the black cracks, poked out half of his body, and then waved to Amber.

Amber shouted in surprise: "Huh?"

The figure raised his hand, pointed directly above, pointed hard, and then gradually disappeared.

"What's wrong?" Gao Wen noticed Amber's distractedness again. He found that the other party was staring at a corner where nothing was left, and immediately spoke, "What are you looking at?"

"I seem to see someone... a shadow resident?" Amber blinked and woke up and found that there were no cracks and figures in front of him. "Strange, how could there be cracks here... I can't even sense them..."

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

"Auntie..." Sonia's expression was stunned for a moment, but she still looked up and looked at it, "The roof. There is the magic cloud top outside..."
