Floating in mid-air above the base of the Sentinel Tower, powered by anti-gravity technology, is the tower's most important "function", a shield projection device known as the "Stone Monument".

The energy barrier of the Great Wall relies on the "Stone Tablet" to maintain, but the function of the Stone Tablet is not limited to creating a layer of shield, as a powerful magical facility, the Stone Tablet has a very complex structure and function inside, it also assumes the role of the upper sensor while making the shield, monitoring the barrier situation at a height of thousands of meters in real time, monitoring the energy tide within the wasteland, and will report its own status to the demon spirit mind in the pedestal at any time.

The array of sensors in the stele may be the last unit that can malfunction and bypass the demonic mind.

"There's a lift platform on the top floor of this room that gives you access to the stele," Banner said quickly as he opened a new interface on the alloy pillar next to the demon's mind, checking the system, "let me see...... Thanks to the spirit of the forest, the lift platform is in good condition. ”

Gawain nodded: "Let's go to the stele and have a look." ”

With no objection from everyone, Gawain arranged for Thorderling and the Ranger warriors to continue to keep an eye on the situation in the pedestal, while he and Banner and the others went to the upper level of the room where the Demon Mind was located—a circular lifting platform was quietly moored in the recess at the top of the room.

The platform had been moored here for seven centuries, but the Sentinel Tower's protective system kept it in good condition, and after Banner injected it with magic and control commands, light blue magic lines and faint elven runes immediately appeared on the ground of the circular platform, and Gawain felt a slight jolt under his feet, and the entire platform began to slowly rise.

The layer of magic cloud tops that emitted a misty glow gradually approached in the field of vision, and an energy shield to protect the passengers automatically rose around the lifting platform, but Gawain didn't care about the magic cloud above his head and the shields around him, almost all of his attention was on the magic patterns that appeared on the surface of the lifting platform.

This is the elf's anti-gravity technology...... Far more advanced than humans.

It only needs a small amount of mana to carry a considerable load up, and its float is incredibly smooth, and its runic structure has apparently been optimized so well that Banner requires little additional manipulation over it......

Humans also have floating magic, and there are also floating devices based on gravity-based spells, and in the towers of the great magicians, they often use similar floating platforms to transport people or goods, but Gawain knows that those floating devices have a fatal flaw - they consume so much energy that they can only be used in mage towers, and they are not easy to control, so that they need the tower spirit of the mage tower to assist in controlling them so as not to fall, and they are expensive and complicated, so that only mid-level to high-level transcendents can afford their costs......

The researchers at the Rune Research Institute have been trying to crack and optimize humanity's gravity-based spells, but they have encountered a similar problem to the original teleportation: a technical black box.

Gravity spells are not created by humans, its origin is a mystery, there are also a large number of unexplained structures in the spell model, Jenny and her technical team have worked hard so far, but they have not been able to optimize the large-scale anti-gravity magic circle to the extent that it can be practical, so far, the only achievements of the Rune Research Institute in gravity spells are "weight reduction" and "floating tricks", the former has been applied to the field of construction and material transfer, and the latter ...... Due to the extremely small load and the problem of multi-array parallel interference, it has not been applied so far.

In the past, the technical black box of telecommunication was cracked after the introduction of the Eternal Sleeper technology, so the technical black box of gravity-based spells ...... Will you find a breakthrough in the elves' knowledge system?

The floating platform continued to rise, it drilled into the thick layer of magic cloud top, the mist of light filled everyone's sight, the arc of electricity generated by the friction between the magic and the platform shield crackled around, Amber seemed to be frightened by this seemingly dangerous "walk-through", the goose subconsciously shrunk its neck, and Gawain was still thinking about the application of anti-gravity technology-

Breaking free from gravity and soaring into the sky is something that almost any intelligent creature will aspire to, not to mention its significance in the military and civilian fields, but more importantly, the technology to break free from gravity is also something that Gawain has always had in mind - in his lifetime, in the conceivable realm, this seems to be the only way for him to touch those satellites in space and touch his "essence".

On this path, griffons can't do it, giant eagles can't do it, and mages can't do their personal flying skills.

As long as the conditions are ripe, the aircraft must be manufactured.

The floating platform passed through the magic cloud top that was more than ten meters thick, and the crackling arc and mist gradually sank to the foot, and beyond the platform, there was a stunning open view.

The walls of astonishing scale stretched out in front of the eyes like an aurora of light falling into the earth, outlining the borders of the ancient Gondor Empire, in the north, the undulating outlines of the dark mountains at the end of the view, and in the south, the purple-black corrupted earth stretched as far as the eye could see, with jagged strange rocks and withered plants scattered across the plains, and some distorted and shapeless ruins appeared in the distance, looking bleak and vast.

Amber stared at the scene on the other side of the barrier in a daze, and then exclaimed, "Wow......"

"That's Gondor, the most powerful empire in human history, from which the ancestors of Ansu fled seven hundred years ago," a memory from Gawain Cecil came to mind, and Gawain broke the silence as he looked at the wasteland to the south, "Do you see that reddish ribbon?" It's that road, and we're killing a fifth of us along that road. And the crooked ruins in the distance, which looked like they had melted, were Thranduran, the last frontier city still organizing the Resistance. Charles tried to persuade the lord of Thranduran to flee with his people immediately, but the stubborn old earl insisted on living and dying with the city. He ended up detonating Thranduran's mana pipes, and those crooked things were the remnants of mana pipes. ”

Everyone listened to Gawain's story quietly, and even Amber couldn't help but be quiet, and in this brief silence, the entire lifting platform entered a shadow—

It arrived at the lower berths of the stele.

After a short period of adaptation, the group's eyes adjusted to the dim magical light inside the stele, Amber blinked, looked around, and then was surprised to find that the huge stele was actually not very spacious - there was only a circular hall within sight, the hall had a high roof, but the highest was no more than a few tens of meters, and she didn't see any other exit except the hall.

Neat silver-white metal pillars stood in the hall, and those metal pillars may have been the monitoring and control devices of the stone monument.

"The vast majority of the stele is cordoned off, wrapped in thick artificial rock and a dozen layers of magical materials," Banner explained, "because the stele is filled with very powerful energy, which is extremely dangerous, and it must also keep its energy environment closed to prevent the shield from becoming unbalanced, so we have to seal it." The walls of this hall are ten meters thick, and they are connected by a huge magic circle set up on the roof and the stone monument, through which we can understand how the stone monument works. ”

As he spoke, Banner walked over to the silvery-white metal pillars, and he activated one of them, and intricate elven runes appeared on the surface of the metal pillars, accompanied by a slight humming sound, and a large number of illusionary projections showing data appeared in the air around the pillars.

Gawain and Sonia were nervously watching Banner's work, hoping that Banner would find something out of the ordinary, but at the same time worried that they had actually discovered a major failure in the Sentinel Tower, the most important structure of the Sentinel Tower, and almost all the failures that occurred here were fatal, if the problem was really here......

I'm afraid the whole barrier repair and reinforcement plan will become a joke.

Amber also watched Banner's actions for a while, but she really didn't know anything about elven runes and didn't know how the Sentinel Tower worked, and after a while she lost interest in what was in front of her and began to look around.

Today's successive "visual hallucinations" made her very concerned.

She's a rough girl, and there's a big part of her personality, but that doesn't mean she's heartless (although many people think so), and she doesn't simply classify what she's seen before as "dazzling", but she's very clear that only she can see those things.

That's a projection from the Shadow Realm, or ...... It is a phenomenon that occurs after the Shadow Realm partially invaded the real world.

Is there a Shadow Rift here? Why does the nature have shadow rifts out of thin air?

Amber frowned, trying to relax her mind, letting her innate, unexplainable gift of shadows take over her five senses, she breathed softly, her gaze sweeping across the hall.

She began to try to observe the place through the eyes of a shadow creature.

Most of the figures seen below were Shadow Dwellers - Shadow Dwellers had no communication with the creatures of the material world, and even seemed to have a certain amount of malice, but they were more ...... to her Closeness, Amber doesn't know if the Shadow Dwellers' attitude towards her counts as closeness, but she does have the experience of dealing with each other.

Those strange, seemingly illogical inhabitants are in fact intelligent beings who do not show themselves this direction for no reason, unless there is something here that disturbs the order of the physical world and the shadow world...... Stuff.

"The device here also shows that everything is in order," Banner's slightly confused voice rang out not far away, and the elven magister repeatedly checked several of the stele's key sensors, his tone full of confusion, "strange...... Normal is just not like words......"

Sonia also came to Banner's side: "Looks like the sensor is working well. What about the connection to the demonic mind? ”

"Smooth connection, wait, it's too smooth......"

Banner and Sonya's voices became ethereal in Amber's ears.

Her hair had grown long and floated in the air as if it had lost its gravity, and her eyes had turned an eerie pale gold, reflecting the black and white landscape of the Shadow Realm, and a wriggling cloud of smoke gathered beneath her feet, creating a passage to the Shadow Realm.

She entered the Shadow Realm.

Hollow, eerie figures wrapped in rune cloth appeared around her, and the hollow figures murmured in low voices, "You're in big trouble......" "They've already done the damage...... "But it seems you can delay a little." "That doesn't have anything to do with us...... "It's just that I need to remind you that you belong here after all......" "Look up and look up."

Amber looked up at the roof of the hall.

Massive hatching vines and roots entrenched on all the silvery-white metal pillars, spreading across the walls of the hall and burrowing through the fissures in the mooring area of the lifting platform to the outside of the stele.

They seemed to be connected to the pedestal below, to the earth beneath the pedestal, to the wasteland, to something more blasphemous in the depths of the wasteland.

"Damn!!"
