The long years of hanging in the sky as a surveillance satellite did not change the essence of Gawain's personality, but it gave him a special perspective on everything in the world—when necessary, he could analyze the changes in the world with an almost onlooker attitude, and summarize some possible laws from the changes that often lasted for thousands or tens of thousands of years, and these laws are difficult to summarize for the species living on the earth (including those elves who can live for thousands of years).

It was because he had seen the many ups and downs of civilization on the surface that Gawain could surmise that the Demon Tide had happened more than once—even if he hadn't captured any of them, it was enough to guess what had happened in the middle from the surveillance footage before and after.

In another speculation of Gawain, it is believed that the scale of the demon tide should be uncertain.

A large-scale tide could lead to the reshaping of an entire planet's civilization, and a small-scale tide, the destruction of Gondor seven hundred years ago, is probably just a "small tide".

Although it destroyed the most powerful Gondor Empire in human history, its scope was limited to the central region of the continent, not to mention the Silver Empire of the Elves and the Dwarven Kingdom in the west.

Or...... Seven hundred years ago, it was not a formal magic wave at all, but just some kind of "prelude"?

Gao Wen involuntarily had all kinds of guesses and associations in his mind, many of which were actually made up by himself out of thin air, and Amber next to him looked at Gao Wen for a long time without moving, and finally couldn't help poking his arm: "Hey, what do you want?" ”

"Just thinking of one thing," Gawain woke up and asked casually, "You say, what would happen if one day all the resources on the earth that humans were familiar with changed, such as the properties of various magic materials?" ”

Amber was stunned for a moment: "Why do you have such a big jump in your thinking......"

Gawain tapped Amber's skull, "Just say what's going to happen." ”

"Then everyone must be in a mess," Amber replied casually, "especially the mages, they probably can't find the spell materials all of a sudden, and many of the spell materials have to be resumped......

Gawain heard Amber's answer, and after a long silence, let out a soft sigh: "Mortal civilization is really fragile...... Right. ”

Amber's ears twitched, "It's strange how strange you speak. ”

Gawain stood up and turned his head to look at Holm and the other members of the exploration team who were waiting beside him, who did not dare to come forward to disturb the lord while he was thinking, and only then did they get closer when they saw Gawain get up.

"This ore needs a name," Gawain nodded slightly to Home, "I'll name it HomeRough." ”

"Big ...... My lord? Holm, who had been a serf not long ago, was startled when he heard Gawain's words, and he repeated with wide eyes in disbelief, "Home's rough stone? This...... I'm not in a good place! How can I have this honor......"

"Discoverers are always great when exploring the unknown," Gawain said, waving his hand, "and we may find more valuable things in this land in the future, and naming them after them would be an easy way to do it – and it would be very motivating for explorers to do their jobs." ”

"Yes...... Thank you! Holm straightened up suddenly, for the first time in so many years, his waist, which had been stiffened by heavy labor, was straightened again, and it even made a crunch down his spine that hurt his entire back, but he still tried to straighten his body, "I...... I ......"

This civilian, who is shallow and can barely read and write, couldn't find the right words to describe his feelings, and Gawain didn't care about this, he just waved his hand: "Everyone in the exploration team has merit, I will let Hetty record it for you, and convert it into a reward according to the contribution bill." ”

Then he looked in the direction of the mountain road, where he had seen a soldier running up, standing still on the mountain road, waiting for him.

"What's going on?" Gawain approached the soldier and asked.

"My lord, I have brought a report from the ruins," the soldier straightened up and saluted, "The Byron knight has found a strange magic device and a hall full of runes in the lower area of the ruins, I hope you will see it for yourself." ”

A new area has been discovered in the depths of the ruins?!

Gawain frowned, and immediately beckoned to Amber: "Come with me." ”

The two men were led by soldiers up the mountain, and after a long journey, they finally reached the deepest part of the ancient facility.

"It's so big in here......" Amber couldn't help but sigh as she looked at the tall corridors around her and the dim magic crystal lamps on both sides of the corridors, "It takes so long to walk in a straight way......

"This is the result of the way that the Byron knights have cleared." Gawain nodded, he noticed that the magic crystal lamps in the corridors on both sides were newly set up, considering the cost problem and the output power of the portable honeycomb magic net unit, those magic crystals were very far apart, so the overall lighting in the corridor was very dim, but compared to the original completely dark ruin environment, the corridor that was now restored to lighting was still much stronger than before.

In that rotunda, Gawain met the middle-aged knight who had not been seen in days.

The many days of exploration of the ruins did not make this knight Mr. look haggard and tired, his state was even surprisingly good, it seemed that in the process he rediscovered the feeling he had when he was a mercenary, Byron's face looked bright, and as soon as he saw Gawain, he greeted him: "My lord, you should take a look at this!" I'm betting that the two texts on the door describe what this room does—but we didn't understand what it meant after studying it for a long time. ”

Gawain looked in the direction of Byron's finger and saw that on each side of the entrance to the rotunda was a metal plate with no signs of rust, and the metal plate was engraved with neat ancient characters using a technique similar to laser etching.

"The left side is written to pay attention to safety and prevent accidents, and the right side is written to pay attention to the personnel leaving the scene and lock the door - what's wrong?"

Byron: "......"

On the spot, Gawain saw several soldiers behind Byron blushing, if it weren't for the pressure of military discipline, they probably would have the heart to roll on the ground.

"Don't bother to study things that aren't your own specialty in the future," Gawain sighed and patted the middle-aged old fritter knight on the shoulder, "I can't even recognize all these ancient words, what are you making a fuss about." ”

Byron broke out in a cold sweat, he turned around in embarrassment and pointed to the center of the rotunda: "...... What you said is that you might as well come and see this......"

Gawain looked into the center of the hall—in fact, from the moment he entered the door, he had already noticed the strange thing that was so full of presence.

It was a ring embedded vertically in the ground, and about a third of the structure was buried deep underground. The inner diameter of the ring is about four meters, and on the ring you can see dense magic patterns and symbolic imprints, and rare metals and magic crystals are embedded in the magic nodes everywhere, indicating that it must be some kind of energy-hungry device.

On the ground around the ring, you can see an equally complex and large system of magical symbols, as well as several metal devices fixed to the ground and connected to the surface magic patterns, which look like consoles.

"It's ...... Some kind of door? Gawain touched his chin, the shape of the ring made him think of something similar to a portal, but he was skeptical of the judgment of the "portal" - even in the heyday of the Gondor Empire, the long-distance teleportation spell was still a theoretical product, and this world did not have such convenient spatial teleportation magic, if there was a mature portal in the era of Gondor Starfire a thousand years ago, it could not have been handed down at all.

It is more likely to be a "magic door" for small-scale spatial transformations, linking different spaces at the same coordinates, a technique that was quite mature in the Gondor era.

"We initially suspected that it was stone, but in fact it was some kind of metal, but no one knew the material," the Byron knight continued, "and we also found several sealed rooms on this level, and those rooms were stacked with ingots of the same material as the rings, as if the people here had planned to build more rings or expand them—but they later withdrew, and the work was put on hold." ”

"Unknown metal...... Gawain muttered to himself, "If it's not ancient alloys, then it's only the Demon Tide that caused them to change their nature, and if it's the latter, then it's a big problem to study." ”

The Byron knight didn't hear clearly: "My lord, what did you say?" ”

"No, it's nothing," Gawain waved his hand, and out of the corner of his eye, he noticed that Amber had somehow run to the ring, and was poking the purple-black crystals on the surface of the ring with her little baby pimple dagger, and he suddenly cried out, "Hey! What are you doing! This thing can't ......."

"Don't worry, I won't steal!" Amber immediately glared at Gawain, and loudly cleared off the suspicion of her occupational disease, "I just feel that the residual power fluctuation of this crystal is a little ...... Familiar. ”

"Are you familiar?" Gawain was taken aback, "Have you ever seen this crystal?" ”

Amber looked at the crystals embedded in the rings like an expert and scholar, and touched her smooth chin with her free left hand: "Based on my years of experience in crime......

Gawain: "...... What? ”

"Ahem, work experience, work experience," Amber reacted to herself, and quickly changed her words, but unfortunately everyone at the scene had already heard it, so she cheekily continued, "According to my experience, this crystal should be the rare Shadow Affinity Crystal - the most expensive of all elemental crystals. And to be honest, the purity is also terrifying, and shadow crystals of such high purity are rare now. ”

"Shadows?" Gawain blinked, he knew the existence of elemental crystals, this special magic crystal was generated by long-term erosion and transformation of ordinary magic crystals in an environment with high element concentration, due to the scarcity of shadow environments in nature, it is even rarer to maintain a shadow environment for a long time and the concentration reaches the standard, so the elemental crystals of shadow tendencies are the most expensive and rare, although Gawain Cecil was known as a polymath back then, but the main skill points are in herbalism, wilderness survival, territory construction and monster cutting, Not much has been studied about magic crystals, but it is not surprising that Amber has seen this crystal as a person who dares to pry into the grave of the founding duke, and who is a shadow affinity and a mad hanger in her own right.

"Could it have something to do with the Shadow Realm?" Gawain asked, guessing.

Amber patted her chest: "Then I'll go in and see the situation first!" ”

"Wait a minute," Gawain grabbed her arm before entering the Shadow Realm, "take me in." ”

Amber was stunned, and suddenly remembered the terrifying experience of facing the flesh and blood of the gods when he entered the Shadow Realm in the Ruins Laboratory last time, and suddenly broke out in a cold sweat, and quickly grabbed Gawain's arm: "Then you have to walk in front later!" ”

Gawain glanced at the half-elf who suddenly got up with a smile, and waved his hand: "Let's go, let's go." ”

Amber took a deep breath to calm her mind, and then activated her natural ability of Shadow Affinity.

The familiar trance struck again, and Gawain felt that the scene in front of him began to shake, but just when he was about to see the scenery of the Shadow Realm, Amber beside him suddenly let out an "oops", and then the two of them "fell out" of the critical state in unison.

Amber rubbed her skull in a daze, and it took a while to react: "It seems to be ...... Ejected? ”
