Now that I have what I need to fight the Void Beast, it's finally time to go serious.
"[Lifeblood: 200%]!"
Lifeblood, one of my oldest, simplest, but most trustworthy powerup skills, was technically limitless. The only limiting factor for it was the penalty if you used it beyond your body's capacity.
At the 9th stage, my body could hold the backlash of 100% output without side effects, practically able to keep it running 24/7. However, it's not like 100% is the maximum.
Activating 200% output would lead to a quite heavy penalty, losing almost a year of my lifespan in one minute. But at the 9th stage, my lifespan was basically stretched to over 200 years, so I could spare some, at least.
'There's no use for my remaining lifespan if I'm dead anyway!'
