Xiao Xun immediately sensed that this 'cave' was indeed emitting powerful energy fluctuations.
These deep-sea octopuses were created by the Ancient Gods, possessing some of their bloodline and thus part of their power. Once they used this Ancient God's blood, it meant they were fighting for their lives.
"I've already slain the King of Arrogance, would I still fear you, a prefect?" Xiao Xun sneered inwardly.
The King of Greed's power was inferior to the King of Arrogance, and so were his subordinates.
At this moment, his battle with Kazik had already consumed considerable time. Xiao Xun had familiarized himself with his abilities and was no longer prepared to delay.
However, just as he was preparing to enhance his own power to completely resolve the prefect Kazik, the ground beneath him trembled slightly.
Soon, he discovered that something was amiss... the source of the tremor seemed to be very far away!
"What kind of tremor is so violent that it can be felt even on this island? Could it be a major earthquake or a volcanic eruption undersea?"
"Damn it, I was tricked by Posidule and the King of Greed. They didn't just set up this one magic array!" Xiao Xun was shocked and enraged.
He had originally thought that the magic array on the island had been destroyed by him and that he would no longer have to worry about the demon god Nero's return. Thus, he had wasted some time fighting the prefect Kazik.
However, although Posidule's description of the island was not false, she had concealed the most crucial point - the magic array for destroying the ley line nexus and summoning the demon god Nero was not confined to just one location on this island.
Xiao Xun immediately drew his sword and severely wounded the prefect Kazik. He did not bother to kill him and instead used his spatial ring to return to the fortress stronghold on the defense line.
The opponent had clearly known about his teleportation ability all along and had specifically targeted him. By the time he rushed over, the summoning of the demon god Nero had likely already been completed.
Moreover, because the summoning array was located at the bottom of the deep sea, the dragon race could not help, and even the submarine forces were rendered useless.
"That is the merfolk's home ground. What exactly does Posidule want to do?" Xiao Xun wondered.
Posidule's stance always seemed difficult to fathom. If she were still wholeheartedly serving the King of Greed, there would be no need for her to secretly discuss cooperation with him and Meist.
But if she intended to betray the King of Greed, then what was the purpose of all she was doing now?
"She is probably still fearful of the King of Greed and is in a state of indecision. However, it's useless to ponder these matters now. The demon god Nero's return is likely unstoppable, and we must prepare for battle."
"Did the merfolk race's summoning ritual succeed?"
When Xiao Xun returned, Delvana and the others, seeing him safe, finally had their worried expressions dissipate.
However, Pear still looked troubled, clearly knowing what had happened.
After Xiao Xun explained the situation in detail, Delvana's face immediately showed concern.
As a divine race, she was well aware of the disaster the opening of the Gate of Darkness in the past had brought to this world. Rebuilding the Gate of Darkness now would undoubtedly lead to a new catastrophe.
"We must find a way to stop it..." Delvana murmured, but she had no good solutions.
The resistance and pressure from the seawater were immense, making it difficult for ordinary humans to wield their weapons underwater.
Although the elves had stronger physiques than humans, they were accustomed to fighting in forests, and their swimming skills were even inferior to humans.
The phoenix army, most skilled in fire magic, was completely unable to fight underwater.
"It's impossible to send troops for large-scale underwater combat; we can only wait for the demon god Nero to emerge."
Xiao Xun also abandoned the idea of sending a large army for underwater combat, as it was too impractical.
Especially fighting the merfolk and deep-sea octopuses underwater would be disadvantageous.
However, Xiao Xun did not believe that the demon god Nero would remain at the bottom of the sea after arriving in this world.
Furthermore, given the demon god Nero's insane nature and being sealed in the outer realms for such a long time, he would not be able to resist coming for revenge upon returning to Saint Roman.
"The demon god Nero will definitely not stay underwater forever. We can prepare on the sea surface and wait for him," Pear said resentfully. The hatred between the dragon race and the demon god Nero was not slight.
"Last time, the King of Arrogance... Svain, do you know anything about it?" Pear asked, looking at Xiao Xun with a smile.
"Not very well. However, I know quite a bit about the King of Arrogance. That guy once tried to control me, but my mental will was very strong. Not only did he fail, but I also killed him."
"You killed the King of Arrogance?" Pear and Onyxia showed astonished expressions.
"Oh, then did you get any useful information?" Pear asked curiously.
"That guy was very cunning, not much useful information. However, it is said that there are even more powerful beings controlling those demon kings from behind."
"There are more powerful beings behind the demon kings?"
This time, not only Pear, but also Delvana and the others showed astonished expressions.
Even though Pear, as a dragon princess, knew a lot of information from ancient times, she had never heard of more powerful beings behind the demon kings.
"Those demon kings are already so powerful, what controls them... wouldn't it be as powerful as a demon god?"
"Pear, you don't need to think too much about it. Such beings are actually not of great concern to us." Xiao Xun smiled. He was not worried about how powerful the Void Lord behind the demon kings might be; that was not an issue he needed to consider at the moment.
What he needed to do now was to eliminate the threat that the King of Greed was about to bring.
"Hmm... such powerful beings are indeed not of concern to us. That would probably be a battle between true deities," Pear nodded thoughtfully.
The deities she spoke of were naturally not the so-called Elemental Archmagi of Saint Roman.
Delvana knew little about this, which saved her a lot of trouble. Aries stood quietly by the side without speaking, her gaze fixed only on Xiao Xun, as if he were the only one in her eyes.
"We don't know that the King of Greed, although powerful, is very cowardly. Especially after the King of Fear and the King of Arrogance were just defeated."
Demon kings originally liked to use all sorts of mental powers to influence and bewitch others, while they themselves hid in the back, watching everything with ease.
While this was safe, years of habit had made the demon kings exceptionally cautious.
Or one could say cowardly...
"Then the ones we will directly face are the King of Greed and the merfolk, perhaps also many deep-sea octopuses. I will go back and call people now. This time, I will personally lead the dragon race to the sea to deal with those merfolk and the King of Greed." Pear's eyes flashed with a strange light, indicating that her hatred for the merfolk was indeed considerable.
"Yes, I will also lead the maritime and aerial forces of the phoenix army into battle."
It was not easy to set up defenses on the vast sea to deal with the demon god Nero.
