Having abundant Demon Lifespan Years, what truly limited Shen Yi's progress in cultivating techniques were actually the two Hall Masters, who unlike Shen Yi, didn't have a panel to help reduce 99 percent of the torment.
During each moment of deduction, both of them were truly experiencing the passage of their lives.
This kind of torment had even caused some Demon Souls to collapse in the past.
Although Ke Shisan and Yue Tianji were strong in spirit and not comparable to those Little Demons, the complexity of the Unity Realm Stage Immortal Law was by no means something that could be discussed in the same breath as those Qi Refinement Realm spells.
Of the Lifespan Years they consumed, almost half were transformed into Demon Origin to help stabilize their minds, while incidentally seeing if they could improve their Lower Grade.
In front of Immortal Law, even Shen Yi's mediocre aptitude was compensated for.
It was truly a case of equality for all living beings.
