[System notification: 5 Obsidian Stones obtained.]

...

A series of system notifications sounded.

As Mcgee opened the golden treasure chest, it appeared in his ears.

They were all strange materials.

Mcgee looked at the materials in his hand with a curious expression. What exactly were these materials used for?

Without blueprints, these materials were no different from a pile of junk.

The materials they used were mostly stones, steel plates, wooden planks, and the like.

Could it be that humans used special materials a thousand years ago?

If that was the case, Mcgee still needed to find blueprints that humans had used before.

Otherwise, would he have to develop his own home system?

He was too naive!

After all, the version had been updated for so many generations. Could the version from 1,000 years ago still be usable now?

There was a question mark in his heart.

However, the reward that appeared, in the end, was in line with Mcgee's expectations.

[Congratulations on obtaining 'Frost Giant Ape's blessing'.]

[Effect: All castle defense structures have their defense against water-type spells increased by 100%.]

This was not the sea level rise version, but Mcgee knew that during the ice and snow season, there would definitely be water-type familiars as well.

After increasing their defense by 100%, the probability of their home being attacked was reduced.

With the departure of the Giant Frost Ape, the entire Whirlpool Islands had fallen into a state of silence.

He did not expect them to be so efficient, leaving just like that.

Mcgee and the Snow Spirit Fox strolled along the streets of the Whirlpool Islands.

The shops beside the streets had all been emptied, and they still looked a little eerie and terrifying.

"Why are they in such a hurry to leave?" Mcgee asked.

"I guess they yearn for the world on Earth," the Snow Spirit Fox said with a smile. When it was trapped in the center of the ocean, it had also had such thoughts.

When Mcgee was walking in the city of ice and snow, he found something strange.

If there were only 132 Frost Apes.

Why did they build such a huge city?

Moreover, it seemed that they did not have the facilities to store food.

At this time, they had already walked to the edge of the street.

"Oh my God, there's a forest here?"

Mcgee was shocked by the scene in front of him.

Under the sea, there was a forest formed by seaweed and coral.

There was a sign at the entrance of the forest.

The word 'danger' was written on it.

Obviously, the Coral Forest was an existence that even the Frost Giant Ape feared.

"There's a dangerous aura inside," said the Snow Spirit Fox.

"Just look at the sign at the entrance."

Mcgee asked, "If I want to go in and explore, will you come with me?"

"Of course. I'm not as cowardly as you."

The Snow Spirit Fox walked in front of Mcgee with her head held high and her chest puffed out. "Follow behind me."

The Frost Giant Ape was a level-8 familiar.

If it was a Coral Forest that even they could not control...

What kind of terrifying existence would be inside.

Mcgee decided to contact the people in his home first. After all, if he left for too long...

The people in his home would be worried.

They were now members of the same boat. If anything happened to Mcgee, the entire home would be finished.

"Hello, everyone. I'm currently at the location of the whirlpool southeast of the map."

"There's an abandoned city here."

"There might be a lot of treasures inside. If you're interested, you're welcome to come and look for them together."

Mcgee posted an announcement on the world channel.

This was the first time Mcgee had posted his location on the entire server.

"Is it really big boss Mcgee?"

"Big boss Mcgee has always been at the forefront of the world. I'm impressed that such a hidden place could be discovered."

"But, why would big brother Mcgee share these things with us? It's not like his style."

Although Mcgee had a gentle personality and had a good reputation in the world channel.

In this survival world, trusting the netizens easily was the biggest concern, so even Mcgee did not go immediately.

"Sorry, I sent the wrong channel."

Mcgee explained that he originally wanted to tell his family members, but he did not expect that he would send it directly to the world channel.

This explanation was more convincing than other reasons.

The crowd suddenly became excited.

"Okay, since I have nothing to do at home, I'll come and join in the fun now."

"Bring me along."

Of course, there were some diving players in the world channel, such as the second and third-ranked players, who originally relied on sled dogs to search for food in the snow.

They dragged them on the snow aimlessly.

After hearing this, they immediately turned around and moved toward the Snow City.

"Why are you doing this?" The Snow Spirit Fox tilted her head and looked at Mcgee.

"Because this city is too big. It's impossible for one person to explore it," Mcgee replied calmly.

"Of course, that's not the most important thing. In addition, this city may have unimaginable dangers."

The departure of the Frost Giant Ape had turned this city into an empty city.

However, according to the nature of the game system...

They would not place such a large reward in such an easy place.

Aside from the thousand-year-old golden treasure chest, it could be considered a reward for activating the mission.

There must be other rewards hidden in the city. Of course, there were also new dangers.

Right now, he only had the Imperial Dragon armor and the Snow Spirit Fox as helpers? As long as there were more than five level-8 familiars, he would not be able to handle them.

At that time, he would need a large number of cannon fodder.

Moreover, although the Frost Giant Ape had emptied the city, who could guarantee that there would not be anything left in the city?

"Let's continue moving forward."

Mcgee left the matter to the people in his home. Even the Flood Dragon and the Little Spirit Fox, who had been sleeping in, wanted to rush over to help.

But it would take them more than half an hour to get there.

So Mcgee decided to explore the Coral Forest first. The longer he stayed in the ice and snow, the worse it would be.

He and the Snow Spirit Fox stepped into the Coral Forest made of coral and seaweed.

It was a world they had never seen before.

Compared to the frozen crystal ground outside.

In the forest, whether it was coral or seaweed, they were all alive.

And there were many mountains made of crystals inside

Mcgee happily took out a knife and dug a piece out of the crystal mountain.

What he cut out was a small piece of crystal stone.

As expected, the crystal stone had a system notification.

[Level one energy crystal, mass 500 grams, grade: superior.]

This crystal was actually an energy crystal.

Mcgee suddenly thought of the thick layer of crystal floor on the city floor.

He did not expect the Giant Frost Ape to be so extravagant as to use a level 1 energy crystal to cover the floor.

After all, these energy crystals could allow everyone to upgrade the castle to level 4.
