A week has passed.
I have made massive progress.
Fuelling Rotten Chi through my body is still something I have to consciously do, but it's becoming more and more natural.
I've also been building my base physicality as well.
I don't have a weapon and I don't plan to get one.
Hand to hand fits me much better than swordsmanship.
It feels more natural. Plus I don't have a sword...
Shadow Boxing is the only thing I can really do.
I have nobody to spar against.
I don't know why.
Well- I do know why, but I don't know about something else.
I can't stop training.
Maybe it's the environment, but I just can't stop.
It's so fun…
I'm watching myself grow in real time. Every moment I spend working the more my itch to actually fight gets stronger.
I sigh and look up.
I'm not a battle junkie, right?
I mean I haven't even fought yet, no way I'm a battle junkie.
It's normal to want to test out what you've trained for, right?
I keep looking up and frown.
The Western Air Temple was carved into a cliff. As such, the roof above me was the inside of said cliff.
I crouch down, filling my body with Rotten Chi, a deep disgusting murky black colour covers my body, as I leap as high as I can.
It's a bit strange considering that Yuta's Cursed Energy colour is Purple, not black, but I assume it's because of the difference in the Energy being used.
I managed to lift myself extremely high off the ground, about a quarter of the way to the roof.
Enough to be confused for an air bender.
That's with Rotten Chi though.
I want to be strong enough to move like a novice Airbender even without Rotten Chi.
Rotten Chi is a force multiplier, the amount infused acts as the number for the multiplication.
But if I increase my base strength, I can increase the effectiveness for my Rotten Chi usage.
It might be impossible for a normal humans, but ATLA as a series has a more comedic focus, meaning I may be able to grow stronger than what should normally be possible as a human.
I'll just try to get as close as I can.
But all this training feels awfully familiar…
But it also feels incomplete.
I don't have enough equipment.
I frown.
Should I just give up for now?
It might be better to explore through to world and look for someone who can properly teach me techniques.
Or to at the very least get some cash and commission some good workout equipment.
There's only so much I can do in terms of bodyweight exercise. I haven't grown much in terms of physical ability, after all it's only been a week, but in terms of Rotten Chi control, I've leveled up a couple classes from where I began.
As well as that, if I get lucky and find a Rotten Spirit with a Rotten Technique, I could figure out how to use my own Rotten Technique…
Alright.
It's decided then.
My current goal will be to find a village so I can commission long term training equipment.
As well as to gather knowledge.
I've been assuming that I'm before the awakening of Aang, but if I'm after…
Well I don't wanna think about it.
Gathering information on the date is important.
On that note, something else I've realised is that...
Rika can hear me speak.
Even when she's inside the ring.
That's proven by the fact that she comes out whenever I ask for her.
I'd rather neglect her, but I don't know what kind of disastrous consequences that might have.
So I've been trying to put myself in the habit of speaking some thoughts out loud in order for her to feel more connected.
Though it's proving difficult. I think faster than I speak and when I start talking about what I'm thinking as I'm thinking it my words can't keep up, so I've accidentally developed a habit to be pretty quiet all my life.
I've been acting how I normally have this week, merely as a test.
She hasn't seemed to have seen any discrepancy in personalities between 'Me' and 'Yuta'.
This Rika is original to this world with no knowledge of Jujutsu Kaisen.
Meaning that thankfully I don't have to meld my personality around Yuta too much.
I assume whichever ROB sent me here made the Yuta who Rika knows have a personality similar to mine.
Though I still have to observe more to see if that's true. It's a bit of a gamble, but I trust that Rika won't do anything rash as long as I have this face…
Now, how do I get out of here…?
Could I scale the cliff…?
If it's just body strengthening, then my Rotten Chi is almost inexhaustible at the moment.
I sit myself down on the floor and place my hand on my chin as I begin to think.
Well, I could use more Rotten Chi to strengthen myself further, but Rotten Chi seems to give diminishing returns when used excessively.
I can't just stuff more Rotten Chi in my body and expect it to be stronger, after all there's only so far pure brute force can get me in terms of physical ability.
But that isn't the case within Cursed Energy though…
Rotten Chi is multiplicative in terms of strength, as I said, but I think the number decreases the more I input.
The amount of Rotten Chi I normally use, about a 4% of my total Rotten Chi amount per minute, can be considered a 10x Multiplier to my strength.
But for every extra percent I add, the less the multiplier grows.
5% is 15x, 6% is 17.5x and so on and so forth.
It seems to get halved per percent I use…
Is that perhaps because the active, the used, Rotten Chi is somehow resonating with the passive, the dormant, Rotten Chi in my body to enhance my ability?
So the more I take from the Passive the less the multiplier grows?
Then I assume if I somehow unlock the rest of my Rotten Chi, or find a way to use my Rotten Chi more efficiently, I'll grow in strength proportionately?
The reason I use 4% is because its an amount that only slightly exceeds my Rotten Chi regeneration. I gain back around 3% per minute for a net loss of 1% per minute.
But that does mean that as I use my Rotten Chi, my strength will decrease since there will be less Passive Rotten Chi to resonate with that Active Rotten Chi.
Considering I'm thinking in Percentages, when I begin using Rotten Chi to enhance myself I have around 99% left due to my regeneration.
1% of 10 is 0.1. So rather than a 10x increase like I said, it would be more accurate to call it a 9.9x increase in strength, but the difference is negligible.
That should continue onwards though. Currently, for each 1% of Passive Rotten Chi I lose, the multiplier on my strength directly lowers by 0.1.
So whilst the 15x from 5% of Rotten Chi would normally be advantageous, and what I would probably use in combat, it wouldn't be suited to a long term activity like climbing.
If I would put it in a mathematical formula, it would be…
(Strength Multiplier / 100) x Net Rotten Chi Loss = Multiplier Loss/Minute
So for 5% per minute it would be…
(15 / 100) x 2 = 0.3 Multiplier Loss/Minute.
Meaning after 10 minutes, my Strength Multiplier would be a mere 12x instead of the usual 15x. It would also mean I would have used up 30% of my total Rotten Chi reserves…
Which can be extended indefinitely.
Which can also be used in conjunction with another formula to find out the multiplier for each percent…
Which I can't currently figure out.
If I had a graphing calculator I could probably do it, but right now I'm ill-equipped for such an equation.
I may be smart but I'm not a super genius.
However, I really don't need to calculate that formula.
After all, using some common sense, any number after 10% would have an increase so small that it wouldn't be worth calculating.
If I do some quick maths… 10% would be…
10 + 5 + 2.5 + 1.25 + 0.625 + 0.3125 + 0.15625 + 0.078125 + 0.0390625 + 0.01953125 = 19.98046875
Round that to 20 for simplicities sake.
Either way, the number gets astronomically smaller from then on.
Though it's important to remember that the 10x I began with isn't entirely accurate, it's close enough considering I don't have an accurate way of measuring how much stronger I've gotten. Although It seems to be a 10x increase, or at the very least incredibly close to 10x. It's safe to just say it's 10x because there is no real practical difference if it's a little under or over.
So for now I'm going to stick to three general amounts of Rotten Chi usage.
4% for General Everyday movement or strength needed tasks.
5% for Combat and heavy duty strength needs.
10% for Last Resorts.
Either to run away or land a blow.
I pause, realising I've been absentmindedly writing down the equations into the floor before wiping it away.
Fuck. Even in another world I'm doing math…
Well, I do enjoy maths. It's my strongest subject after all, but even still I shouldn't be doing something like this.
I should be having shounen style battles using the power of friendship, or whatever.
I mean that's a bit of a stretch but…
You get what I mean.
I look up again.
"Well I better start climbing now…" I say with a bit of a groan.
My muscles are gonna kill me after this.
Oh yeah, aren't I supposed to be thinking out loud for Rika to hear…?
"Fuck me…" I whispered under my breath.
I guess it's time to explain all that again.
