After just one session with the marrow meditation manual, Leo gained significant insight into the technique.
Although it wasn't as mentally demanding as the mind meditation manual, it was incredibly strenuous in other ways.
The practice of the manual demanded immense patience, precise mana control, and unwavering consistency and while these factors didn't actively tax his mind as much, they still posed a considerable challenge to maintain over time.
After just one session, Leo realized that it was going to take him several years at minimum to fully master the marrow meditation manual, as even if he could generate enough cells to meet his body's replacement rate today, it would still take another year of rigorous practice to perfect the method.
Moreover, reaching the cellular replacement rate itself was a long and arduous process and for now at least it was a goal way out of his current reach.
