"President Xu."
"President Xu."
In addition to Elder Undine, the other figure is Cassandra in human form.
Xu Yi glanced at Cassandra and didn't ask why she was here.
With Akali’s good relationship with Cassandra, it’s not surprising that she told Cassandra the news here.
Besides, when it comes to the Abyss Demon Clan, if the Dragon Clan, which has a history even longer than that of the Elves, is involved, it might be even more helpful.
"Have you been waiting here for a long time?" Xu Yi asked casually, turning to look at the wall in front of them.
Just by taking a quick glance, you can tell that this wall should be made of the same material as the pillars of the ruins discovered earlier.
However, when the pillars of the ruins are not stimulated, they look similar to ordinary stone pillars, but the wall in front of them is emitting a gentle but bright light.
The light in the previous passage should have come from here.
"We've been here for a while, but we still haven't found a way to get in." Elder Undine responded.
"Actually, we discovered this place last month, but we just couldn't get in." Akali explained.
"Really?" Xu Yi raised his head and found that he was actually in a very open space at this time. At least tens of meters above his head, he could vaguely see a layer of rock wall, and the rock wall in front of him The wall extends all the way to the top, forming an arc top shape, but there is a large space separated from the top rock formation.
It seems that the magic shield covering the outside of this wall can not only separate the sea water, but also all other impurities.
The seabed outside has been completely covered with a thick layer of rock over tens of thousands of years, but the surroundings of this wall still remain the same.
"If this is the ruins of the Abyss Demon Clan, then the technology of the Abyss Demon Clan is really amazing." Xu Yi sighed, and then asked Akali: "Why don't you use the magic perspective projector to see what's inside?" Condition?"
Akali shook her head: "I tried it, but the magic signal fluctuations can't penetrate the wall at all, so I can't see what's going on inside."
Xu Yi was a little strange: "Didn't you use the magic perspective projector to see the situation inside the ruins stone pillar? Why can't you see through this wall?"
"Then how do I know?" Akali said angrily.
Xu Yi pondered for a moment. Then he asked Elder Undini and Cassandra: "Do you have any records about these things among your elves and dragons?"
"No." Elder Undini shook his head simply.
"This is the first time I even know about those so-called ruins." Cassandra even knew less than Elder Undine.
Xu Yi knew that he didn't need to expect these two representatives of the race with a long history to be of any help to him. He could only walk to the wall and take a closer look.
The wall in front of you is not everything, whether it is left or right. Still going up, there is actually a space separated by one layer and the rock layer.
Xu Yi walked around the outside of the wall, flew up and observed it from above, and found that it was not a wall at all, but a semicircular dome building.
This building is about twenty meters high. The largest diameter below even exceeds two hundred meters.
If it were hollow inside, the space inside would be astonishingly large.
After Xu Yi flew around, he didn't find anything strange, so he had no choice but to give up.
Of course, Akali and the others discovered this place last month. If there was anything unusual, they would have discovered it long ago.
"President, have you figured out how to get in?" Akali looked at Xu Yi expectantly.
Xu Yi sighed and shook his head.
"No way, I can't even find a single crack. This thing is just like an egg shell. But I think it must be related to the relic stone pillars we discovered before. As long as we can study those stone pillars thoroughly, Maybe we can find a way to open here.”
Akali was a little disappointed, but she also knew that Xu Yi was right.
"Could it be that you finally made a new discovery, but you can only watch it?"
"What's there? It's here, and it can't escape." Xu Yi reached out and patted the wall. Feeling the thick touch in return, he turned to Akali and smiled: "We still have plenty of time anyway. You can study it slowly, no need..."
Xu Yi suddenly noticed that the faces of Akali, Elder Undini and Cassandra in front of him all showed expressions as if they had seen a ghost.
"President, you... you..." Akali pointed behind Xu Yi with wide eyes, a look of shock on her face.
"What's wrong?" Xu Yi turned around in confusion. Momentarily stunned.
On the originally seamless wall behind him, a rectangular gap nearly three meters high and more than four meters wide was opened!
"No way..." Xu Yi was surprised and looked inside along the gap, but he could only see a neat passage leading straight inside, but couldn't see anything specific.
"President Xu, are you actually an abyss demon?" Cassandra said with a shocked look on her face.
"Nonsense!" Xu Yi immediately shook his head. "The Abyss Demons disappeared more than 10,000 years ago. How could I be."
Of course, Kassandra just made a joke casually, and Akali and Elder Undini didn't think much about it at all.
Elder Undine pointed to the exposed passage: "What should we do now? Go in?"
Everyone was hesitant.
This place is full of weirdness, and if there is any danger inside, they may not be able to handle it.
Akali thought for a moment, gritted her teeth, and strode inside.
"Now that we are here, how can we be afraid of coming and going!"
Xu Yi smiled slightly and followed Akali in. At the same time, he gathered all his magic power and increased his vigilance.
Elder Undine and Cassandra looked at each other and followed.
It turns out they filtered.
The passage was not long, and after walking about ten meters, a light flashed in front of them, and an extremely huge and open space appeared in front of the four of them.
Xu Yi raised his head and took a look, confirming that the space inside was similar to what he had just estimated outside. It was indeed a semicircular dome building.
In terms of volume alone, it is probably enough to cover a standard basketball stadium.
However, in this huge space, looking around, there was nothing.
The only thing that caught everyone's attention was a huge pillar standing in the center of the space.
Akali flew over without hesitation and looked around the pillar for a long time. She even flew up to observe the top of the pillar. When she finally landed, she said with a strange look on her face: "This pillar... I'm afraid it's the same as those pillars outside. , but why is it the only one that is tightly wrapped?”
"It's different." Cassandra looked up at the huge pillar, which was at least over twenty meters high and two to three meters in diameter, and denied Akali's statement. "At least this pillar is much bigger than the ones outside."
"If I guessed correctly, this pillar should be the core part, so it should be protected more carefully." Elder Undini guessed.
"Well, I agree with this speculation." Xu Yi also said.
Akali thought for a moment, raised her hand, and took out a delicate instrument from the magic space she carried with her.
This instrument is the magic perspective projector developed by her, Elder Undini and the Crescent Chamber of Commerce.
The Akali magic perspective projector was aimed at this huge pillar, and a magic illusion was displayed through the instrument.
Akali, Elder Undine, and Cassandra glanced at the illusion and spoke at the same time.
"It's indeed the same!"
"Is it the same as those pillars outside?" Xu Yi asked.
"No... not exactly the same." Akali shook her head again, carefully observed the illusion for a while, and nodded affirmatively. "Yes, there are many details that are different."
The four of them observed the illusion for a while and exchanged looks at the same time.
"President, I can confirm it. These pillars should be the huge magic array left by the Abyss Demon Clan, which they used to travel to another world. And the largest pillar in front of us is this magic array. Core."
"That is to say...as long as we can activate these pillars, it is possible to activate this magic circle, and then go to another world like the Abyss Demons?" Cassandra asked in surprise.
"This..." Akali and Xu Yi looked at each other, smiled bitterly and shook their heads. "I'm afraid it's not that easy. First of all, the Abyss Demon Tribe went to another world. It's just a legend. No one knows whether they succeeded or not. If they fail, then activating this magic circle is asking for death. Secondly, even if They succeeded, but...how should we activate this magic circle?"
"Of course..." Cassandra opened her mouth, unable to continue.
Although so many ruins about the Abyss Demon Clan have been explored and some secrets have been deduced, they still don't know more about these pillars, so how do they know how to activate this inferred magic circle
"It's actually very simple." Xu Yi smiled. "Since the Magic Illusion Projector has been able to detect the situation inside these pillars, we can imitate them and then conduct various experiments and research. One day we will be able to know the secrets hidden in these pillars."
Akali glanced at the illusion again and exclaimed: "President, although you can't see it clearly, the instruments inside are very high-end at first glance. How can we imitate them?"
"How will you know if you don't try." Xu Yi laughed.
"Anyway, in your eyes, President, no problem is a problem." Akali rolled her eyes. "But I still have a very important question. President, for more than a month, we have tried various methods but can't get in. Why did the outside door open automatically when you came? ?Have you been here before?"
Elder Undini and Cassandra also cast doubtful glances at Xu Yi.
This question is indeed too incredible. (~^~)
