After staring at the collar curiously for a little longer, he shook his head before turning away. If not for overhearing the men speaking of the properties of the collar, he wouldn't know the uses of it.

Even though he would very much like to study the collar, he couldn't afford to stay here. From what he could tell, these people were all in the Overlord Plane. Luckily, they were only in the Early stages. Although he felt he could take them on one on one, he wasn't confident when it comes to fighting against this group.

'We're leaving?' Void asked.

Grey nodded to his question, this had nothing to do with him so of course he wasn't going to get involved in it.

'Oh, okay,' Void replied before turning away as well.

The duo walked away from where the group was camping, heading in another direction. Since this group could camp here, then it probably meant it was safe for him to also do the same.

He walked at least one kilometer away from where the group was before finding a spot to rest.

He set up an array around the place they set up camp before sitting down crossed leg. Since breaking through, he hadn't properly cultivated to make his stage stable. Even though it really wasn't necessary, he enjoyed doing this.

Void sat down watching him, after staying for almost one hour, he stood up and disappeared into the bushes. Of course, he didn't forget to tell Grey he was going for a short exploration.

Grey was sure to warn him severally before letting him go. He knew Void didn't like staying idle so he didn't try to stop him.

….

The next morning.

Grey opened his eyes before the sun rose.

'The essence here is something else,' He said with a shake of his head.

He couldn't help but wonder why those men were still in the Overlord Plane. If Alice, Klaus, and Reynolds were to grow up here, they would've already broken through to the Overlord Plane by now.

'Void, where are you?' He transmitted his voice over when he noticed Void wasn't back yet.

After a few seconds, Void's voice echoed in his head.

'On my way,'

Grey prepared himself for the journey. He planned to follow the group that captured those barbarians out of this place. Since they spoke of an arena, it meant they were headed towards a city.

Void soon returned, and the duo headed straight for where the group camped. By the time they got there, the group was just about to begin their journey.

Grey and Void didn't say a word, silently following behind them as they started their journey.

….

Five hours later.

'Stop, there's a magical beast ahead,' Void said to Grey.

'Oh, how powerful?' Grey asked.

'They are all Rank Five beasts, all in the early stages,' Void replied.

'Rank Five?' Grey thought to himself before counting mentally to figure out the strength of the beasts.

'That's the Early stages of the Overlord Plane, right?' He asked just to be sure.

Void nodded while staring at him oddly.

Grey scratched his head in embarrassment, although Void had told him of what the power system of magical beasts is called, he was still used to using the power system of humans.

'You said they, how many are they?' He asked after a while.

'I'm not too sure, I can't sense them properly, but they should be around nine to fifteen,' Void replied.

'All in the Overlord Plane?' Grey asked.

'Yeah, all Rank Five beasts,' Void answered.

'Hmm, this will be interesting. Guess I'll be able to gauge the strength of these people from this battle,' Grey thought to himself.

He wanted to see if the people here were more powerful than those of the same stage in the Azure continent. To be honest, he was a little pessimistic about it since even the essence here is way better than the one in the Azure continent.

The duo followed the group but kept a considerable distance, they didn't want to be noticed by the beasts.

Ten minutes later.

"Oh no, where is there a horde of Fire Apes?" One of the men in the group asked angrily.

"Damn it, they've already noticed us," Another man with a scar on his left wrist said, he turned to the others, "Prepare for battle, no matter what, don't let them get close to the barbarians,"

"Yes captain," The others answered in unison.

They set up a wall around the cages, protecting the barbarians from the Apes. The collar could be destroyed by an external force, so they couldn't afford to let the Apes get close to the barbarians.

Roar!

"They're here, set up the array," The captain of the group ordered.

The group arranged in seven different locations with the barbarians in the middle, forming a hexagram shape when looked from above.

They all did a hand seal before a light shot up from their hands, shooting upwards. The lights reached about ten meters before linking together to form a light screen that protected them.

….

Grey, who was watching from the side, found something odd, "Why haven't they tried to fly?"

"I don't know, but I think the intensity of the essence here makes the air heavier than that side, making it difficult for those in the Overlord Plane to take flight here," Void explained after a while.

Since he was already a Rank Five magical beast, then he could fly. He tried flying but it was a little difficult.

"It's a little difficult, but I can still fly. Others wouldn't be able to fly though," Void added after trying to fly once again.

"Hmm, okay. Looks like there are a lot of changes here," Grey muttered before staring at the Apes which had flames around their body.

….

The Apes attacked as soon as they encountered the group.

The attacks of the Apes slammed into the light screen that appeared around the group.

Boom!

The Apes' attacks were unable to destroy the defense of the group.

"Attack!" The captain of the group ordered.

Boom! Bang!

Roar!

The group's counterattack dealt major damage to the two Apes at the front, causing them to roar in agony.

The array the group set up has the ability to defend and attack, making it almost impossible for the Apes to get to them.

Grey and Void couldn't help but commend the efforts of the group. Although there were arrays like this back at the Azure continent, none of them was this powerful. From Grey's estimation, the attack of the array was at the very least equal to an attack of a Mid stage Overlord Plane Elementalists, and the defense seems to be around the Late stages of the Overlord Plane.

'This is an interesting array, I wonder if there's a way I can modify it?' Grey thought to himself while watching the battle.

Just from looking at the array, he has been able to not only decipher it, but he has come up with different ways to immediately break it within the short time of two minutes.

Given Grey's current knowledge of arrays, even Chris would be surprised by how far he has grown. And from Grey's personality, it was evident that he would not only improve further, but he would also create new arrays.

….

Fifteen minutes later.

The array made by the group was still standing, while the numbers of the Apes had started to dwindle, with bodies lying on the ground. Of the thirteen Apes that came to attack the group, five of them were dead, and two were seriously wounded.

"Haha, this array is amazing! It's totally worth every stone we spent on it," One of the men in the group laughed out loud happily.

Although the array was slowly draining their essence energy, it should be able to last at least one hour more. There was no way the Apes would be able to survive until then.

Three minutes later, another one of the Apes fell. On seeing how their numbers were slowly dwindling, the Apes immediately retreated from the battle. Although their knowledge couldn't be compared to that of an adult human, they were still smart.

The group stayed in the array for a few more minutes, waiting for the Apes to completely leave the area before they destroyed the array.

"Pack up their bodies, they will fetch us a good sum as well," The captain ordered.

The group immediately got to work, first removing the cores of the six Apes, before storing their bodies. One person could only keep a single Ape in their storage ring, this showed how small the space inside was.

….

When Void saw the Apes retreating, he couldn't help but shake his head in disdain, "Stupid things, I could easily destroy that array with a simple attack, yet they all couldn't,"

"They only believed in brute strength, unlike you who is smarter than them," Grey said.

"Even if they couldn't break the array, couldn't they at least escape sooner? *Sigh* I feel ashamed classifying these dumb fools as magical beasts as well," Void shook his head in dejection.

Grey chuckled when he saw this. Void was just too prideful, although he couldn't say he didn't have the right to be since he was not only smarter but more powerful as well.
