Rohan mind was reeling not because of information but the implications of information he was getting was causing his heart beat wildly. He has seen and read anime and novels about apocalypse and all that, but it is occurring here and he is the cause of it. What are effects, how many lives will be effected, all kind of what and how's are banging in Rohan's mind.
He took a deep breath and asked "what can I do Arya? Is there any I can stop it? If not how can I reduce the effect of apocalypse on my planet?"
Arya looked at Rohan being genuinely disturbed for the first time and that reminded her that even if he is smart and have brilliant mind, he still a teenager and being told that an entire planet can be destroyed because of your actions, that can have huge pressure but he still asking for solutions.
[Don't worry calm down, I am here to help you. First of all there are few ways, you can choose which way to save your planet. Second, you should not stop it although it is dangerous but there are still ways you can salvage the situation because that happens to every living planet after a planet evolve or its inhabitants become strong enough but here is case of premature awakening but you are here so I am pretty sure you can find multiple ideas to help your people.
The main obstacle in your way is your power level, you have to increase your power so that you can interfere and save earth from danger.]
Rohan felt little positive after hearing Arya's explanation and asked "what power level I need to reach and what are the ways to safeguard my planet?"
[Let me tell you about Power system which is applicable everywhere,
Mortal --> Planetary --> Celestial/Star --> Quasar --> Galaxy --> Universal
This is the power level you can know, there are stages after Universal but you will know about them in future. As for you to have the best way to save your planet and its future, you need to be at least Galaxy level if you can reach Universal level all the better.
There are to ways to increase your power level from now, first, comparably easy way is to increase energy capacity to particular level but it's not recommended for you. Second one is best and more favourable for you is to increase your understanding in the Authority you practice. In your case that is primarily Creation Authority or if someone else follow other Authority then they have to increase their understanding in that.
To reach certain level, these are the requirements in understanding your Authority
Celestial – 3% ; Quasar – 6% ; Galaxy – 10% ; Universal – 20%]
"So my understanding of Authority is 1% and I have to increase it to at least 10 times for minimal interference or 20 times for best result, okay, next is how much time do I have and ways I can help?" Rohan asked with serious tone, racking his brain for all possible way to minimize the damage.
Before Arya could reply, system chimed in with notification
[New Mission – Safeguard Earth
Mission :- The Planet of The Successor of The Creator is in danger of being annihilation due to early awakening, find a way to save the planet and it's people.
Reward :- Based according to results
Time :- 4 months]
When Rohan saw this he was relieved that he has still time to come up with solutions, only thing hindering his way was his understanding of the Authority. So he asked the most important question "Arya, how do I increase my understanding of Authority and reach required level for saving my planet?"
Arya promptly answered [First let me tell you what Authority means, Authority is upgraded version of your Talent. In Mortal realm you can use your talent on a miniscule level to perform certain feats according to your talent but when you get to Planetary level your talent grants you Authority according to your talent.
There are few ways to increase Authority but I will tell you one which suits you best. To increase Authority, you have to understand the basis of your Authority and how it works and make that Authority yours. You are unique case since Creation Authority is already yours and no one in entire existence can have it.
You only have understand your Authority and you can do that by using it to create more complex and intricate things be it skills, tools, living beings. Increase your creativity and create anything you want. The more you create the more you will understand your Authority. It's an arduous process and being a Supreme Authority, it's hardest of all because you can't increase your understanding just by creating same things, you have to innovate and create something from your own thoughts.]
Hearing detailed answer from Arya somewhat settled Rohan, now he has a way to move forward but still being naturally curious he asked "you said that I am unique case since only I poses Creation Authority but what about other who have different types of Authority/Dominion, how do they increase their understanding of Authority?"
[Okay, I will give you an example which will simplify things related to other authorities. Let's say if someone has a Talent of Fire mage/Fire manipulation then that person will get Authority of Fire. Now many people can have talent related to Fire, so most will get Authority of Fire, there are cases where people with extraordinary talent, will and perseverance can create new type of Authority but they are very few and that Authority necessarily won't always be better, but it will be talk of some other time.
So now if a person on Planetary level gets Authority of Fire then if that person wants to advance further, he/she have to understand their Authority and develop their Authority according to their life experiences and personality other things that affects the holder of Authority.
So even if two people have same Authority, the effect and result of use of Authority by both people would be different. That is to say that many people may have same Authority but no two people produce same effect under one authority. One person with Authority of Fire may result in destructive effect and other person may result in purifying effect and many more.] Arya replied in detail about Authority and its effects according to user of Authority.
Rohan absorbed the explanation because even if he has Creation Authority, he still wanted other authorities, so he was glad he got to know how to move ahead related to other authorities. He asked "Arya, so now I know how to move forward, how much time will it take me to reach Galaxy level or if possible Universal level within 4 months and what ideas can I implement to safeguard my family, my planet and it's people?"
[Well...it normally take a genius more than 1000 years if provided with good resolution to reach Galaxy level from Planetary level. As for Universal level add 10000 years more. Now before you start racking your brain about your situation you should check the reward for reaching Planetary Realm from system, it will be of great help in your current predicament.
As for ideas for safeguard, first you check your reward then we will talk about options.] Arya explained.
Rohan breathing almost stopped hearing the first half of Arya reply but after hearing about reward, he remembered he got something for completing quest and he hadn't bothered to check due to upcoming apocalypse. He released a breath, even he didn't know he was holding then said "Okay let's check what system got in store for me."
