In front of Kahn, a long and elongated door with pulsating borders as if it were a living being was created and through this gateway Kahn could see a different dimension that seemed existent and non-existent at the same time.

And to pique his curiosity, this void crack that he just opened after getting a little bit of understanding about the space law seemed exactly similar to the surrounding area. However everything inside it was a combination of black, gray and white.

"Phew! Let's hope I don't die inside." spoke Kahn and walked into the door that seemed to be sucking the air around him.

Clink!

As soon as Kahn entered the void crack, the pathway closed behind him and now he stood inside what seemed like a different dimension. It looked exactly like the chamber where he was practicing space law before but at the same time, he felt like everything here was completely different.

Because unlike the real world no mana or world energy existed inside this place and even the floor he was standing on felt like standing on quicksand that would soon engulf him.

Tap! Tap!

Kahn kept walking inside this mirror dimension and noticed that time functioned differently here. He threw Lucifer in front of him but instead of quickly falling down it was suspended in the air and slowly started coming down as if time and gravity itself were many times slower and lighter compared to the real world.

At this exact moment, he also noticed that the intangible force he used to create the void crack encapsulate his entire body, clothes as well as lucifer that was still suspended in the air.

"Ah, I see. So this space force is what's keeping me and my possessions safe inside this dimension.

No wonder one needs to master space law first. Otherwise, if their body is not able to withstand the surroundings inside this dimension without having this force protecting it.. They'd instantly die because the time and gravity would slow their movements, blood circulation and even their breathing.

It's like outerspace with no air and the gravitational force that would instantly kill you." spoke Kahn as he understood another important fact.

The space law was the most important factor for Kahn to improve his Dimensional Law divine ability because if not for his understanding and the space force he created to gain access to all the space around him he would've died as soon as he entered the void crack.

By developing this force and his body adapting to it, Kahn had basically created a protective shield that completely protected him in every aspect and allowed him to roam free in this mirror dimension he probably became the only person to be able to do it in the entire Rakos empire.

After a few minutes passed and Kahn ventured into different rooms and corridors of this mirror dimension he suddenly felt like his body was drained out.

"Fuck! My body doesn't have enough space force to stay here longer!" exclaimed Kahn and quickly used lucifer to create another void crack.

Thud!

He quickly jumped out of the crack and the gateway behind him closed instantly.

"Phew! Made it right in time." he spoke.

Kahn then took a deep breath and he could again feel the mana and world energy around him as he returned to the normal world where everything wasn't just black, gray and white.

And soon, Kahn's body felt the familiarity of the living world, unlike the mirror dimension that basically existed in both planes at the same time.

"So that's the real plane of existence and the one we're living inside is the plane of reality that is occupying it and is filled with other laws of reality." said Kahn as his knowledge kept expanding from the experience he had just now.

He looked around and noticed that it was indeed the same training facility but the difference was that he entered the void crack from the library and he exited that dimension from a different place.

So in other words he could use the dimensional void crack to enter from their plane of existence, travel inside the mirror dimension and then exit it to return to the real world but at a different place.

And no one would be even able to sense or feel him since nobody else other than Kahn had access to this true dimension of reality.

And most importantly the time there moved differently. Means if Kahn needed to move to a place where it would take him an hour to reach he could do it from the mirror dimension but the time in the real world would also be very short for him and he could reach the destination in a matter of 10 to 20 minutes instead.

Kahn became curious if the time and space of that dimension would become slower if his mastery over the space law kept increasing gradually over time.

After having this eye-opening experience, he returned to the library and touched the core to absorb the mana and world energy again to create another void crack and explored the mirror dimension again.

This time, he exited from a place 100 meters left. He followed this same procedure again and again, to explore the dimensional by creating void cracks and always exited from a new place.

After 5 hours of constant practical application and exploration he finally heard the system notification.

[Space Law mastery improved by 1%.

All the range of Dimensional Law abilities and skills increased by 0.1%.

Current maximum range : 110 meters.] informed the system.

"Great! This is definitely something that would've cost someone else years of study and practice." he said in excitement.

"Man Only if I could study and practice it day and night." he spoke with a little disappointment. Because practicing this space law and increasing his efficiency required a lot of focus, time and energy.

"I wish there were more of me" he spoke and the next second.. Kahn's eyes widened with a realization

"Wait a minute"

The next moment Kahn gave a sinister smile and suddenly, on his left, another Kahn appeared out of nowhere.

Kahn finally used the Doppelganger skill after almost a year.

"System, the doppelganger shares all my abilities and skills as well as my consciousness at 50% stats, right?" asked Kahn to the system.

[Yes.]

"Then it will also share my mana and world energy as well, right?" asked Kahn in a curious expression.

[Yes. The host shares a direct soul connection with the doppelganger so even the world energy and mana are shared between the host and the replica as long as the activation period of the skill is on.]

The next moment both Kahn looked at each other and had a wide grin on their faces and spoke in unison as an evil plan hatched in their minds together.

"I'm a motherfucking genius!"
