So that was it!
Shihōin Naraku's improved physique and spirit had caused the chakra within his body to surge in an extremely short time, but he had not noticed. Whether in combat or while performing Medical Ninjutsu, he had continued extracting chakra as usual, failing to immediately realize that the extraction had become much faster. Without the system's help, the sudden surge of chakra would have burst the pathways throughout his body and damaged his organs.
So the system had intercepted that terrifying amount of chakra, allowing the total chakra within Shihōin Naraku's body to increase only gradually.

Shihōin Naraku knew the system was helping him. Thinking about it, which ninja in the shinobi world with enormous reserves of chakra did not have a strong physique?

Of course, ordinary ninja would not encounter a problem like Shihōin Naraku's. With a weak physique, they would not have that much chakra in the first place.
The key was that Shihōin Naraku was different from ordinary people. His spirit-or rather, his soul-was so strong, so absurdly powerful, that his body simply could not withstand the surge in chakra!

Of course, this could count as a happy problem to have!
"System, according to your calculations, what's the maximum amount of chakra I can withstand?"
[Fifty percent!]
"Fifty percent at most. In other words, unless my physique
