I am an Eldritch Entity?

Eryndor reclined on his bed and opened the file sent to him by the agents of the Human Federation.

The contents were a word-for-word recounting of his earlier exchange with them, a proof of the file's authenticity.

It was locked with the password they had discussed during their conversation at the hospital, ensuring its security.

To confirm their legitimacy, Eryndor had also verified the agents by calling the helpline number listed on the Federation's official website.

He opened it with great anticipation, eager to get in-depth knowledge.

It took him about half an hour to read through the entire document.

There were two important things which it explained about in general.

First was the power system of the Eight Outer Domains. 

The Human Federation, through a series of confrontations over two centuries, were able to get their hands on techniques of all the Eight Outer Domains.

But some of them were incomplete, some had higher restrictions, some had resource limitations.

The Human Federation suggested a few power systems out of all, each carefully selected for their cost-effectiveness or suitability to the current situation, among other factors.

Eryndor condensed the points listed in the document for his own convenience.

This made it easier for him to make quicker decisions, without the need to sift through long, dense paragraphs each time.

Cultivation world: Relies on the energy 'Qi'. The power system is about longevity. 

It has low resource requirements at least in the early stages, fulfilled by the environmental Qi itself, making it extremely cost-effective.

Magic world: Relies on the energy 'Mana'. The power system is about knowledge.

It has high requirements of knowledge from the beginning stage itself. Need extensive knowledge on the subject to form the related spell model.

Not suitable for drop-outs.

Mentalist world: Relies on 'Spiritual energy'. The power system focuses on the use of mind. 

It has low resource requirements, but due to opposition from the higher ups it is strongly discouraged to be pursued in the Academy. 

Eryndor suspected that people felt uneasy when confronting them, likely due to their ability to read minds, a power that could make anyone wary.

No one wanted to cultivate a group of mind readers.

Martial Arts world: Relies on 'Internal energy'. The power system focuses on body refining.

It has low resource requirements and is strongly encouraged by the Academy.

Cyborg world: Relies on 'Spiritual energy'. The power system focuses on modifying the body and relying on external items to rank up.

It has both high technological constraints and high resource requirements. 

The current technology of The Human Federation can only barely perform a rank one operation.

It isn't advised to choose this one as the Federation is unsure when it will be able to catch up or borrow the more advanced technologies for higher ranks.

Beast Taming world: Relies on 'Internal energy'. The power system focuses on contracting different beasts to use their power and make them fight for you. 

It has low resource constraints plus the emergence of new beasts on Earth allows this power system to have a high potential. 

Demon world: Relies on 'Mana'. The power system focuses on pure destructiveness.

Has low resource requirements and has the highest destructive output out of all power systems. 

Due to past incidents, the Academy evaluates the mental state of students before recommending it to them.

Buddha world: Relies on 'Qi'. The power system relies on the mastery of karmic links.

Proficient in divination, location searching. Their attacks are exceptionally challenging to defend against.

It is one of the slowest power systems to get started with, and to continue powering up.

Currently the most mysterious power system. 

Academy discourages students from pursuing it before completely researching it themselves.

Eryndor then jotted down his own thoughts on the power systems, with the most important factor being the speed and ease with which he could begin training. 

He needed something that could be accessed and started quickly.

Cultivation was possible.

For the magic power system, he didn't think he wanted to sit through university lessons again to form some spell models so becoming a mage was out of options.

He could consider it later but right now when he wanted the fastest way to gain power and verify if it could open the door in his mind palace, magic wouldn't cut it.

As for becoming a mentalist, Eryndor wasn't interested in the constant surveillance from the Academy, nor did he want to draw unwanted attention or suspicion from the Human Federation.

Becoming a martial artist was certainly possible, but he didn't like the idea of refining body and having limited range to attack. 

It might be possible at higher realms of power but it certainly didn't seem feasible at lower ranks. 

He would end up being a meat shield. 

Cyborg was a no brainer. 

Even though he wanted to be quick, it seemed unlikely that the Academy would provide him resources for rank one for free. 

He would have to work to exchange the materials for it, which would take some time.

Beast Taming had the same problem. 

It was a quick route and even had a higher potential than being a Cyborg where the Federation didn't have corresponding technology of higher level.

But he likely wouldn't be given the beast for free. He would have to work for it.

Same with the Demon techniques. 

He didn't want to wait till the Academy was done evaluating him psychologically and gave the pass to cultivate the technique.

Lastly, the Buddhist technique.

It was also a no-brainer. 

He had no grandeur delusions of being able to quickly successfully practice a power system the Academy evaluated as one of the slowest.

The Academy has said that one person can practice more than one power system but it is difficult and also discouraged since it means more resources were used on a single person for no quantifiable increase in power.

It is difficult as it is for a person to power up, adding to that another power system, it is like climbing with an extra load. 

I can choose other power systems later after making sufficient contributions if cultivation happens to be unbearable or useless. 

After going through a few more rounds of discussion with himself and searching information on the internet, he ended up choosing cultivation as his path. 

It would be the quickest and easiest way to power. 

If it didn't work out, Beast taming would be his second choice.
