"Hmm," Jyorta frowned, sensing a limitation of sorts. He closed his eyes, comprehending the source while the three Frenzy Beasts feasted on the Lava Turtle carcasses. Jyorta inspected his presence, the embryonic tattoo he had created, and his aura reserves, using all the accumulated data to find the source of the limitation.

"I get it now," After a long time had passed, his eyes shot open, muttering, "Even though I took the presence of the Frenzy Parasite into me, only its presence remains now while the aura accompanying it has vanished."

Aura was classified as the exertion of a being's presence. But, a presence also contained the nature of the being, i.e. its personification. At present, only the Frenzy Parasite's presence remained. As its aura wasn't Jyorta's, it left his body. His aura expelled it on its own.

"Now, if I wish to do anything with its presence, I would have to supply it my aura. Since it is in my tattoo, my aura would act as a steady stream of energy fuelling it. I see…so that is the limitation. My aura is the factor that limits the development of Aura Induction." Jyorta's eyes widened in realisation.

'If I calculate based on the theoretical concept, Aurons.' As he was supplying his aura to the Frenzy Parasite's presence, it could only function when it was wholly supported. Suppose the Frenzy Parasite's presence required 60 Aurons to function, he would have to expend that much to support its actions.

And, suppose his total aura reserve conformed to 400 Aurons, he could maintain the functioning of 6 Frenzy Parasites in his tattoo. As such, he would only be able to use 40 Aurons to battle. And, judging by the needs, the expenditure increased.

As the tattoos were created from aura, they acted as condensed platforms built using it. The greater the aura he used to make it, the sturdier and grander it became. Normally, if he created a castle in his tattoo using his aura, he would only have the creation expenditure in his aura.

After all, in the hallucination, the castle was a rigid object. Once created, it would experience zero changes. But, if he added the element of air to it, then he would have to constantly supply aura into the tattoo to maintain the dynamics of the air. That was a continuous expenditure.

And, if he added more dynamics in the elements, such as air, water, sunlight, etc. he would have to maintain it continuously, which would increase the quantity of aura he would have to infuse into the tattoo every second. The limitation was the amount of aura he could send.

Moreover, the condensation of the aura in the tattoo couldn't exceed the aura in his body. If it exceeded, the tattoo would destabilise. After all, change can only be induced. If the change was greater than the target of influence, it was simply overriding it. That wasn't the essence of Aura Induction.

That's why, even the tattoos he induced in Frenzy Beasts only conformed to their levels. The only difference was the quality and its intrinsic structure surpassing theirs. But, their quantity was always lower than the targeted Frenzy Beasts. This was one of the factors he had to consider while designing the tattoos.

"The size of the world I could create is limited to my aura. So, the size of the hallucination would be the maximum I can exhibit in reality." Jyorta looked around, recalling his usage of hallucination in his stay at the military academy.

If he went all out and focused solely on the aura personification of hallucination, he could maintain it within a sphere of a 100-metre radius. Anything beyond and his hallucination wouldn't be a cohesive structure. It would still be as effective, but any beings encountering the forming gaps would have a possibility of breaking out from the hallucination.

The range further increased if he limited himself to one direction, and reduced the volume. Using the formula for the volume of a sphere, his control amounted to 41,90,476 cubic metres or 0.00419 cubic kilometres.

So, if he just focused on one direction, with the breadth and height limited to 10 metres each, then his range would be almost 42 kilometres, theoretically. Though in reality, the air would just absorb his aura, and reduce its potency fairly early. And, if there was any aura in it, then the range would fall even shorter.

The reason the aura beam was so powerful was because he condensed such a volume into a cylindrical beam with a radius of a metre and below.

"The volume I could use my hallucination is how big the world I create would be. That's my limit. It looks big, but a sphere with a radius of 100 metres is not that big, geographically speaking. Just the Meka Clan alone I witnessed in the Crimson Desert covers an area surpassing 10,000 square metres. And, the sky there felt vast. It might not be as big as the sky in reality, but it still looked vast."

"If I add any terrain dynamics, like wind and water, I would have to constantly use the required brainpower. And, if I add thermodynamics into the mix, the situation becomes incredibly complex. There are also physical and chemical laws to be taken into account. I wouldn't be able to maintain it for long before I tire out. Indeed, creating a world is not easy, even if it is a smaller one."

Jyorta sighed, once again experiencing how awesome Vaika was. Her Crimson Desert was huge and was realistic. It seemed she had incorporated every law in existence into it while overlaying her own laws to create her world. "I wonder how she manages something of that scale? I should ask her when I leave the labyrinth."

As for the concept his world would be based upon, Jyorta had been thinking about it all along. He was still clueless about the dynamics he had to put in place so that the development of all fields would take place, but he got the basic gist of it already.

He referenced a popular trope he had come across in his previous life. It was so good that readers consumed it like crazy and were never bored of it. And, the first of its kind was something even he loved very much.

Tower of God!

"With a tower concept, I can segment the world into numerous pieces. And, each segment would have its own rules and would focus on development in a certain path." Jyorta smiled, this was the plan he had thought of to use his advantage to the maximum.

"Once I learn how Madam Vaika manages her world to reduce the consumption of her brainpower, I should be able to pull it off." He gazed at the Frenzy Beasts resting after stuffing themselves full of the Lava Turtle carcasses.

The River Whale had managed to recover most of its expended energy that Jyorta had used to activate the Tier 3 Relic, Dynamic Brethren Bait.

"As for its progression…" Jyorta thought about the core concept of Aura Induction. It was able to induce a certain effect within the presence of another being. The same was also possible in the reverse. That was how Jyorta was able to induce the presence of the Frenzy Parasite in himself.

Since the presence of a being conformed to their entirety, it also contained records of the Skills or other abilities the individual possessed. As it was a world of hallucination, the presence could even activate those abilities and display the same strength it had in reality.

But, it wasn't an easy feat to achieve. After all, to achieve that, Jyorta had to have enough understanding of the abilities the Frenzy Beast had possessed. Otherwise, even if the Frenzy Beast tried to activate the ability, its effect would be different as the world didn't possess such information.

Moreover, if it was based on imagination, then any Frenzy Beast would be able to activate its abilities at many times its original power level. If the power system depended on imagination or the individual's perspective, then it would lose all balance.

To avoid that, Jyorta must have a solid grasp of their power schemes. That way, he could make the situation conform to reality. As he was a Psychic Parasite, Jyorta was capable of that. All he needed to do was comprehend the individual's memories.

He didn't possess a method to place the soul of the individual into the hallucinated world and attach it to the respective individual's presence. After all, the two of them conformed to different paths. Only when his comprehension of the paths achieved the required level would he be able to achieve something like that.

At present, once he comprehends the memories, he would grasp the complete working of all the respective individual's abilities. That way, his world would have the knowledge and the presence living within would be able to activate it to the same level as it did in reality.

Moreover, here was his true goal. He wished to imbue the concept of Aura Induction in the hallucinated world. That was the plan he had concocted to generate the world's progression.
