The Necromancer's Fourth Catastrophe

At this moment, the two mermaids, after watching the image, began to appeal to Frankie to go to the islands for rescue.

Frankie, somewhat irritated, waved his hand: "You guys be quiet first. I'm thinking about something, and I'll go once I've figured it out."

The two mermaids, frightened, quickly shut their mouths, not daring to make another sound, just looking pitifully at Frankie.

Frankie reached out and rubbed his temples, "It's really strange, a contracted undead creature can't be returned to the Netherworld if it leaves a necromancer's certain distance."

"And if it can't be returned to the Netherworld, the contract can't be relieved, and it can't be summoned nearby from the Netherworld at any time."

"Therefore, a necromancer would never separate their contracted undead creatures too far, otherwise, in danger, they would have no backup."

Frankie took a deep breath, feeling confused on many aspects.

The location of that group of islands is really particularly good, to the west is where he is located.

To the east is an enormous dark reef area, to the south is a deeper part of the Chaotic Sea Domain, and to the north is the territory of the Gana Race.

Since he settled the merfolk on that group of islands, there had been no problems until now.

But now, out of the blue, things have gone wrong.

He couldn't figure out how ten high-tier undead creatures came running from the direction of the dark reef area.

And they just directly charged onto the island.

As if they were originally coming straight for this group of islands.

No matter how you look at it, this situation would never normally occur.

But now it has indeed happened.

The more he thought about it, the more chaotic his thoughts became. Looking at the two mermaids with pleading eyes staring pitifully at him, he stood up in some agitation.

"You just stay on the island with peace of mind. I'll set off to the islands now to find out what's really going on."

Hearing Frankie's words, the two mermaids hastily nodded their heads.

Seeing this, Frankie no longer looked at them and directly stepped out, heading outside.

Once outside, he immediately cast magic, and soon a pair of brilliant light wings appeared on his back. The light wings gently flapped, carrying his body straight into the sky.

This is the top-tier light magic 'Radiant Wings', boasting a considerable flying speed, and these light wings can also be used for defense. It is one of Frankie's favorite light magics.

Because all the knights on the islands had been dealt with, and the mages had been taken away, the merfolk who came to find Frankie were all ordinary merfolk.

They had no magic power waves on them, so naturally, Frankie couldn't perceive them, and as he flew from high above, he couldn't possibly notice the merfolk swimming in the seabed.

These merfolk going to find Frankie perfectly missed him.

As for the island where Frankie lived... even if they found it, it would be of no use.

Because the island where Frankie resided was unlike the islands, with just two auxiliary magic arrays.

Almost all the top-tier magic arrays that Frankie knew were arranged there, and these merfolk simply couldn't get in.

Originally, Frankie thought that when he arrived at the islands, it would surely be a tragic sight.

But when he actually arrived at the islands, he found that it was not at all what he imagined.

The islands had not experienced much destruction, and the number of merfolk living there hadn't noticeably decreased.

This only made him feel even more puzzled.

Seeing Frankie's arrival, a large number of merfolk immediately greeted him, beginning to chatter ceaselessly in lamentation about what they had encountered.

Hearing the noisy voices of the surrounding merfolk, Frankie irritably raised his arm, "Alright, don't speak all at once. Choose one person to speak."

Soon, an older merfolk was pushed forward, who then began detailing the situation to Frankie.

Upon hearing what this merfolk had to say, Frankie not only frowned deeply: "They only killed the merfolk knights on the island and took away the merfolk mages without harming the ordinary merfolk... this is really baffling."

Frankie naturally knew that high-tier undead creatures capable of hosting demon caves could absorb the knight origin of normal knights after killing them.

So he could completely understand those advanced undead creatures killing all the knights on the island, but he really couldn't understand them taking away all the mages on the island.

What did these people want to do with the island's mages? He couldn't think of any reason at all.

Moreover, the undead creatures from the Netherworld, due to their living environment, usually tend to be savage, with very few exceptions.

If they had a contracting necromancer nearby who could restrain them,

Frankie could understand them not slaughtering innocents since not every necromancer likes senseless slaughter.

However, undead creatures without a restraining necromancer didn't slaughter innocents? This made him feel as if he had heard wrong.

After repeatedly confirming with the merfolk, he finally believed he hadn't heard incorrectly.

The confusion in his heart grew deeper and deeper, his brow tightly furrowed: "Those high-tier undead creatures couldn't have flown on a ship? Or those who could fly, were they dragging a ship?"

"Yes, yes," the merfolk immediately nodded.

Frankie frowned and looked eastward, "Alright, I understand. I'll go investigate the situation."

With those words, Frankie flew towards the east.

When he arrived at the dark reef area, he gazed at the dark reef before him, a thoughtful look appeared on his face.

His eyes scanned over the densely packed reefs, and now he was more suspicious. Could it be that they didn't come from the east at all? Perhaps they came along the dark reef from the south and then turned east?

After all, the distance from here to the islands is quite far apart. It's impossible to observe or perceive this place from the islands.

If that were the case, it would be more reasonable, as those undead creatures sitting on a ship, if they continued east, what would happen to the ship? Would they carry it over?

But if they came along the dark reef from the south, why did they suddenly turn west? And then precisely discover the island where the merfolk lived?

You must know, the merfolk had lived on that island for so long, there had never been any problems before.

Now suddenly, for no reason, they were found by a group of high-tier undead creatures, who only killed the merfolk knights on the island and took away the merfolk mages. This is really too bizarre.

In his view, it simply couldn't be explained.

Thinking for a while, his gaze wavered between the south and the east relentlessly.

In fact, he had visited the east long ago and knew that continuing through there was the battle line between the Gana Race and the Sea Elf Race.

Furthermore, something happened over there that left a particularly deep impression on him.
