"This should be safe," Void said standing in front of a cave.

Grey looked around before nodding his head, this place was relatively quiet, and all the beasts he could sense around them were still in the Arcane Plane. It's been a while since he encountered anything in the Arcane Plane, and it was kind of weird for him.

'Looks like this isn't the Magical Beasts' forest,' He thought before setting up an array around the cave. He made two arrays actually, one to protect them, and the other to not only conceal their aura but the aura of the Dragon's blood essence as well.

A high leveled beast's blood essence was a great tonic for low leveled beasts, so even if they caught a little whiff of it, they would go crazy trying to consume it.

'*Sigh* If only I could conceal this mark,' Grey thought to himself while touching his shoulder.

Even with his new knowledge of arrays, he had still been unable to hide it. He even asked for help from the Elder in the O'Brien family, but they were unable to bring up something tangible. All their efforts failed in the end, and he couldn't help but give up.

Instead of wasting his time on it, he would take the opportunity to learn other things from the old man. The old man was very nice since he willingly taught him a lot about arrays that he had learned over the years.

Grey and Void entered the cave and Void took out the rock. He tapped on it lightly and the rock started to crack.

Just from the small crack that appeared on it, an alarming energy leaked out, shocking Grey to his core. He couldn't believe something like this could be concealed so well.

The thought of it amazed him, if the person who concealed this helped him out, then he should be able to conceal the mark.

The rock soon disappeared, and a single drop of blood could be seen floating mid-air.

"Normally, it shouldn't be possible for a human to be able to use this, but you're different, so you shouldn't have any problems, at most you'll die," Void said.

Grey almost fell on the ground when he heard the last part of Void's statement.

What the hell did he mean by at most he'll die? Does he look like someone who would want to risk his life unnecessarily?

"You should be fine, just try it," Void shared the blood essence into two before taking half to one end of the cave and refining it.

Grey stared at the blood essence for a few seconds, unsure of what to do.

"Forget it, I'll take the risk. With the help of the orb, I should be fine," He said before grabbing the other half of the blood essence.

As soon as he held onto it, a massive wave of pressure descended on him, but it soon subsided thanks to the orb which started rotating at full speed. This further gave Grey the confidence that he should be fine with absorbing it.

With everything set, he sat in a crossed leg position and slowly started to refine the blood essence. He wasn't transferring the energy to his core, instead, he was using it to improve the strength of his physical body.

Dragons are known for their strong body and immense physical strength, if this could help him attain something like that, he would be happy.

The blood essence slowly entered his body, before running through his blood vessels. He experienced excruciating pain as the blood entered his blood vessel. The force was so much that it actually destroyed his blood vessel. He healed almost instantly, but it destroyed it once again, not just that, but his skin was also being broken as well from the force of the blood.

The speed at which it was moving increased as time went on. The pain continued, but he gritted his teeth and endured it.

Time slowly passed and day soon turned night.

Even with so many hours going by, he still hadn't completely absorbed the blood essence.

Void's blood essence was already more than halfway used up.

.

The next day.

Boom!

A powerful aura spread out with Grey in the middle, cracks appeared on the wall of the cave, and the arrays he made outside shattered.

"Oh, you're awake," Void said when sensed the aura Grey was giving off.

"Hmm, how long has it been?" Grey asked while looking around.

There was a difference in his aura, he was like a Dragon that was concealing itself, waiting to show off its magnificence.

"A day, I think," Void replied.

"How did it go?" He asked.

He already knew the answer, but he also wanted to hear it from Grey's mouth.

"Very well, I'm already almost on the brink of breaking through to the Overlord Plane, all I need is to crack the last bead," Grey replied.

Unlike other people who needed to crack their beads once, he had to slowly crack his beads then integrate the power into his body. This was why he had been unable to break through to the Overlord Plane even after trying so hard previously.

After finding out the technique, he started breaking his beads. His strength increases every time he breaks a bead. From his estimation, even after breaking through to the Overlord Plane, his strength wouldn't increase by too much.

"You're like a beast right now. You can easily hide in the midst of beasts and not be noticed, well not if they look at you," Void commented.

Grey retracted the aura he was releasing, "It's not bad. It should come in handy later in the future,"

"Do you plan on infiltrating a beast's abode? Cause if you do, I'm up for it too," Void asked excitedly.

"No one's infiltrating anywhere, come on, let's see how things have been in this place," Grey stepped out of the cave, ready to search for his friends.

Locating them wasn't a problem for him though, thanks to the tracking device they all had with them.
