These were huge lumbering skeletons that were far bigger than the normal skeletons.
However, the one thing that they had in common with the smaller skeletons was that they also had three sockets in their heads to symbolize three eyes in life.
Other than that, the bones that they had were a mix of completely different creatures.
Lin Fan was stunned by the appearance of these giant skeletons at first, but then he quickly sent out the balls of strange energy in an attempt to control them.
Luckily, these balls of strange energy were still effective against these giant skeletons.
When they made contact with the giant skeletons, there was a connection that was formed with them just like with the rest of the undead.
However, this connection wasn't made as smoothly as the other undead.
When it made contact, Lin Fan could feel a bit of resistance from the giant skeletons, as if they were resisting his control.
He didn't know if this would happen with the Outer God fragment, but he guessed that it was because he was weaker than the Outer God fragment that they thought that they could break free of his control. However, Lin Fan wasn't weak when it came to spiritual sense because of his contract with Brainy.
So he was able to overwhelm the wills of the giant skeletons and subdue them.
Though, it was a challenge subduing them since their wills were quite strong.
In the end, he was able to control these giant skeletons.
As for the smaller skeletons that he had sent forward, he found that they had been completely drained of all of their strange energy and were lying there as bones.
It seemed that these giant skeletons had the ability to absorb the strange energy just by touch, which was why they had been able to destroy the skeletons that they had scattered.
After realizing this ability, Lin Fan couldn't help wondering…
What would happen if they were to touch normal people that didn't have this strange energy?
What would they drain from them?
There was already a vague answer that formed in the back of his mind, but for the sake of his own mental state, he decided to ignore it.
But there was one thing that was certain, it was dangerous to bring these giant skeletons anywhere other than this place.
Still, there was no denying that he had obtained a very powerful card to use against others.
These giant skeletons could be treated as his secret weapon.
Especially since…even Momonga, Angela, and Yuki felt a sense of danger coming from them.
That meant that these giant skeletons would be more than enough to pose a threat towards normal Rulers if they even threatened these peak Rulers.
After gaining these giant skeletons, Lin Fan still didn't go into the large building as he sent those giant skeletons further into the building to search the place. As he had expected, there were more giant skeletons guarding the deeper parts of this large building.
He had given each of the giant skeletons a ball of strange energy and they used that on any of the giant skeletons that they found.
It didn't take long before the entire building had fallen under Lin Fan's control.
It was only then that they entered the building and started searching it.
There didn't seem to be anything at first as most of the things in the rooms on the lower floors were similar to the things in the smaller buildings. It was only when they reached the higher floors that they found different things.
There were traces of technology and books that were left behind by whoever lived here before.
The level of technology wasn't at the same level as the human race was at currently, but there were pieces of technology that were completely different that Lin Fan didn't know the functions of.
For now though, he just put them away in his system's storage so he could check them out later.
As for the books that were left behind, they were immediately taken by Momonga since he was the only one who could read them in the first place.
It didn't take him long to translate them and figure out what was written on them, but the content was just too much even for him.
This planet…it wasn't a planet that belonged to their universe.
It was a planet that came from the Outer and had been brought over by the Outer Gods as part of their invasion plan.
That was where the three eyed people came from.
As Momonga had said, there had never been a race of three eyed people who lived in this world. That was because they had only existed in the Outer and had been brought over by the Outer Gods.
But when they were defeated, they didn't have a way to bring their planet back and they were eventually destroyed since they were invaders.
The planet had been abandoned since it was filled with Outer laws that the people of this universe couldn't control.
Once he learned this, Lin Fan couldn't help looking at the skeletons that were around him and feeling sorry for them.
While they were invaders of their universe, he couldn't help feeling sorry for those that were caught up in this mess.
After all, there were a few smaller skeletons among the horde that were clearly the skeleton of children.
Their entire planet was brought over, so it was inevitable that those that wanted to leave would be caught up in this mess. They had no fault in this matter, they were just innocent victims of the plans of those with more power than them…
But still, this was a matter that had happened a long time ago, so Lin Fan didn't dwell too much on it.
The only other thing that was special about this large building was a large crystal in the middle of the very top floor.
This was a crystal that was filled with the same strange energy that Lin Fan controlled.
However, it was stronger than anything that Lin Fan had felt before.
If he had to guess, it was most likely that this was the accumulation of all the energy that the skeletons in the city had gathered. Of course, it wasn't just this single crystal, but there would be crystals scattered all around the city in the large buildings.
This would help Lin Fan in developing the strange energy inside of him, but he didn't approach the crystal.
He could feel the immense energy that was contained within the crystal.
It was just too daunting for him to absorb like this.
He was certain that it would overwhelm him and that wouldn't benefit anyone.
After all, he had plenty of time now that he had finished the mission and could come back to this cultivation realm. So he would be able to absorb the energy in the crystal another time, when he had more control over the strange energy.
So just like this, they left everything else behind and headed back to the spot where they first arrived in this realm.
Once they arrived, the system promptly sent them back to the Lin Astral Empire.
With the abilities of the system, the time dilation meant that they were only gone for about fifteen minutes even though they had spent close to a day on that cultivation realm.
Zi Ling had still been standing where they had disappeared and she was shocked to see them come back so quickly.
She quickly went over to hug Lin Fan when she saw that they were back, but then she calmed down and looked at Angela with an awkward look.
Angela just gave a nod and patted her on the shoulder.
Momonga on the other hand didn't waste a single second as he immediately headed off to his private room in the store to conduct his research.
He had brought back all the books that he had found in the large building and he couldn't wait to start going through them.
After settling down, Angela, Zi Ling, and Yuki headed off to have a midnight snack…though it would only be Angela and Yuki who would be eating.
As for Lin Fan, he hung back from the others to check something.
Once they were all gone, he opened up the system and looked at the notification he received.
It was confirmation that he had finished the mission given and also a notification of the rewards that he had received.
There was the access to this cultivation realm that he expected, so he wasn't surprised by that. What he was surprised by was the other reward that he received from the system.
Unknown Key: It's an unknown key.
That was the only description that the system gave him for this item.
When he took it out of the system storage and looked at it, he couldn't help being more shocked.
That was because it was just a simple key with nothing special about it.
No, there was something special about it…
It was completely covered in rust.
This was a rust covered key that didn't have any special marks on it, so Lin Fan really
didn't know what it was good for.
He couldn't even feel an aura coming from this key.
No matter how he looked at it, it just looked like a normal key…
But Lin Fan didn't dare look down on this key since he knew that nothing that came from
the system would be normal.
In the end, he just put the key away and waited to see what was so special about it.
