Summary
The Goal of this "Fic" is to document exactly how Gege Akutami presents the [Ten Shadows] technique in the Jujutsu Kaisen Manga and speculating exactly how it works based on what is and isn't shown. Those chapter endings where Gege Admitted that the math behind the [Limitless] technique made no sense does make this slightly redundant, however even if they don't make sense with the fake math Gege made, he does still stick to the rules he made in the story. I will be gathering every time the [Ten Shadows] is used, talked about and then speculate on the rules Gege follows yet doesn't state.
(I would like to note that this isn't me policing fic writing, a good deal of JJk is about characters interpreting their technique, however as someone who likes complying to lore this technique is by far the most difficult to pin down the rules for outside the basics. If you want your SI-MC to use an open barrier domain and summon 1000 Mahoragas, go ahead, however I'm still making this for general use - and hopefully discussion on whether my opinion is brain dead)
-I will be putting in the hard facts in normal text and putting my speculation and then advanced rambling in (brackets) so you can skip over allat if you don't care.

Summary
Ten treasures bathed in darkness bound in chains. Only shadows cast on walls held their visage, yet had none of their true essence. Futile, nothing but the flailing of the Ignorant. However, among them, one refrained, it was the reflection of the unbeaten, of perfect harmony, waiting.
...
Kage Zen'in had reincarnated - or at the very least had inherited the memories of someone else with uncanny knowledge of the future in the form of a rather fast paced Manga called 'Jujutsu Kaisen' - and all in all he'd say that it wasn't exactly treating him kindly. Though, perhaps the Ten Shadows was a fair trade for such an awful beginning to ones life? That was at least what he told himself... and the portable petting zoo he called a Technique.
And by the time he started puberty, he'd actually gotten back on his feet. Not fully, but enough to firmly set his new goal, to become 'The Strongest'.
Not the hardest challenge, the competition isn't fierce in 2005, but that title was still the standard he'd set in his mind, the realm of power from that battle in Shinjuku. He'd reach that peak, he'd master his Technique, he'd tame Mahoraga.
After all, what other thing than power could give meaning to ones life?
