Six days later, Xu Yi appeared on an unknown island that was around two hundred kilometers to the northwest of the Space Island base.
"Where are the ruins?"
When the Magic Airship stopped, Xu Yi asked the commander of the Magic Airship that brought them here, Santander.
This island wasn't big and they could see it from the sky, but they didn't see anything strange.
"Sir chairman, look over there … …" Santander pointed at the center of the island through the porthole of the Magic Airship.
"Do you see it?
There were a few particularly thick trees, and it was under those trees that we found what appeared to be the remains.
"Un, then let's prepare to move."
Xu Yi nodded before turning to look around. He saw the excited Akali and elder Undine who had a much more serious expression.
"Elder Undine, you are more familiar with these ruins, do you have anything to say?"
This time Xu Yi led the New Flyer's team out of the main base. On the surface, his goal was to head to the Demon Cloud Continent to personally guide the New Flyer's development on the Demon Cloud Continent.
But his secret goal was to visit Akali's overseas research base and ask about the research progress. The other goal was to explore the Abyss Demon Race's ruins in this area.
As for the Abyss Demon Race, the first time Xu Yi heard about them was from Mentor Carmilla, but then he learned more about them from Kassandra.
However, if one were to talk about the initial understanding, it would be through Elder Undine.
The Azshara Tribe had the most complete inheritance among the elven tribes in the Sines. Moreover, they had a part of the inheritance of the elven royal court, so naturally they knew more about the history of the continent than the other elves.
When Xu Yi tried to ask elder Undine about the Abyss Demon Race, the answer he received was far more detailed than he could have imagined.
According to elder Undine's information, the Abyss Demon Race was indeed a powerful race that ruled the Sines before the elves.
Later, due to the internal turmoil, the abyss demons suffered a large number of casualties. As a result, their population was greatly reduced, and they were almost completely wiped out.
It was said that the remaining Abyssal Demons had gone to the depths of the Endless Ocean with their powerful abilities, and then opened a portal to another world. They left this world and disappeared without a trace ever since.
As for what Mentor Carmilla said about the Abyss Demons possibly returning from another world, Elder Undine said that the probability was very low.
This was because the abyssal demons had left this world for more than 10,000 years. If they had the ability or were willing to return, they would have returned long ago.
Since there was no news of any abyssal demons appearing in this world for such a long time, it could be assumed that they had completely disappeared.
This answer disappointed Xu Yi.
Through the various rumors about the Abyssal Demon Race and the records of the elves, Xu Yi was almost certain that the so-called Abyssal Demon Race was actually a race with a highly developed civilization and powerful technological abilities.
Just the "War of Doomsday" of the Abyssal Demon Race recorded in the legends of the elves had fully reflected this point.
In the description of this "War of Doomsday", many texts indicated that the so-called War of Doomsday was a civil war in the Abyssal Demon Race. They used the most powerful weapons they had, and as a result, most of the Abyssal Demon Race died directly, so the population plummeted.
It was precisely because of this reason that the Abyssal Demon Race left this world through the portal.
In the records and legends with obvious speculation, it indicated that the Abyssal Demon Race felt that this world was no longer suitable for their survival, so they left.
This so-called "War of Doomsday" reminded Xu Yi of the doomsday scenes described in many literary novels on Earth.
Wasn't the legendary "most powerful weapon" the same as nuclear weapons on Earth?
In the novels, movies, and so on on Earth, there were countless fantasies of a nuclear war breaking out on Earth, and then the entire Earth fell into doomsday. Humans lost their living space and could only seek for survival.
Wasn't the records about the Abyssal Demon Race very similar to this?
Therefore, Xu Yi's interest in the Abyssal Demon Race became even stronger.
Elder Undine happened to provide Xu Yi with a piece of news that surprised him at this time — the elves actually knew about the ruins left behind by the Abyssal Demon Race!
According to Elder Undine's explanation, the elves appeared on this continent more than 10,000 years ago, but after they appeared, they had been enslaved by the Abyssal Demon Race and helped them do the lowest manual labor.
After the War of Doomsday, when the participating Abyssal Demon Race decided to leave this continent that was not suitable for them to live on, they also asked the elves to help them build a portal, so the elves' ancestors left some records.
However, most of these records were passed down orally, and the authenticity was not high.
However, some of them could be confirmed because the descriptions in all the records and legends were extremely similar.
Most of the contents were descriptions of the Abyssal Demon Race when they left this world.
And in these descriptions, the most important thing was that the elves' ancestors actually left behind the location of the Abyssal Demon Race's portal.
After spending some time with Elder Undine to research this matter, Xu Yi roughly determined the location of the portal that the Abyssal Demon Race used to leave this world — it was near the sea where the Sky Island was located.
Akali chose the Sky Island as the location of the overseas research base not only because this location was indeed suitable for the location of the first magic signal floating in the air, but also because of Xu Yi's private request.
Previously, Xu Yi did not explain to Akali why he did this, but six days ago, when Xu Yi explained the "Abyssal Demon Race" to Akali, he told her everything.
Akali was originally a person who liked to explore and pursue new things. After knowing such a novel thing, she naturally pestered him to come over.
"There's nothing to explain." Elder Undine shook her head.
Elder Undine shook her head, "The Abyssal Demon Race has already left this world for over ten thousand years, so even if there was a mechanism, it would have already lost its effect.
Of course, it's not wrong for everyone to be a bit more careful. "
"Un, it's like this." Xu Yi thought about it and found that there was nothing to add, so he waved his hand.
"Let's go, but remember to follow my orders and be careful."
The group responded and formed a small team that carefully left the Magic Airship.
The two elven warriors and two magicians from the New Flyer were in front of the team. With the powerful senses of the elves and the sensitivity of human magicians, even if something happened, they would be able to react immediately and detect any abnormalities ahead of time.
The strongest ones in the team, Xu Yi and elder Undine, were focused, controlling the magic space around them. If there was any change, they would immediately react.
However, facts proved that they were too careful.
From the beach where the Magic Airship was, to the large trees in the center of the island, other than meeting some blind beasts, they didn't meet any accidents at all, not to mention any danger.
Of course, if it really was that dangerous, the exploration team they sent before wouldn't have been able to find the ruins that easily.
Not long after, the group safely arrived under the exceptionally thick trees.
Xu Yi could see with a single glance that there was an open space under the large trees that was clearly beneficial to the environment.
The open space was in a square shape and it was all made of a special kind of stone. It completely separated the grass to the side, so it looked very strange.
And in this open space that was around the size of a basketball court, there was a thick pillar standing there.
This pillar was even thicker than the large tree that needed two people to wrap around. The surface seemed to be made of stone, but it also seemed to be made of metal, so one couldn't see through it at a glance.
The surface of the pillar was very smooth and didn't have any gaps at all, so one could tell that it was made by man.
This pillar was around ten meters tall and there was a round ball at the top. The material was a bit different from the pillar and the colour was a bit closer to metal.
But other than that, this bead didn't have anything special about it.
"Elder Undine, do you know what this thing is?" Xu Yi asked.
Elder Undine shook her head, "I don't know.
In the records that have been passed down, it only said that there were ruins here, but there weren't any other descriptions.
I guess ….. the elven ancestors back then didn't know what these things were used for or the specific principles behind them. "
Xu Yi nodded in agreement.
Tens of thousands of years ago, the elven ancestors had just appeared on this continent, and had always been used by the abyssal demons. Naturally, they didn't know much about the abyssal demons' civilization, so it was natural that they didn't know this.
"There isn't a single Magic Pattern on it, just what is it for?" Akali patted the pillar, but it didn't move at all.
"Things used by the Abyss Demon Race might not be magic." Xu Yi smiled and shook his head. Then, he walked to the side of the pillar and patted it.
Akali rolled her eyes at him, and said, "You said that the Abyss Demon Race didn't use magic, but you still used magic to detect it. Don't you think you're lying to yourself?"
Xu Yi smiled, and said, "That might not be the case."
The mana in his body moved and began to condense the magical elements in the surrounding Magic Space into the pillar.
Although the technology used by the Abyss Demon Race might have nothing to do with magic, it was still a way of using energy.
Magic happened to be a more special way of using energy, and its biggest feature was that it was very flexible.
Of course, Xu Yi didn't know the original function of this pillar, but there was still hope if he used magic to detect it.
