It made sense because blood was the carrier of the energy and nutrition needed for the wounds to heal, from the rest of the body. He spent some more time estimating the limits of his healing.
Even before he got into the experimentation, he could already theoretically project some of the limits of his healing.
Given that his healing was limited by the amount of energy, compounds, and nutrition that was needed to build new cells.
('That's several kilograms of flesh,') Rui mused.
Martial bodies were much denser and heavier than normal human bodies, which was why the Weaving Blood and Godspeed technique could work for Martial Artists, and not for normal humans. However, even with increased mass, Rui estimated the limit for the amount of tissue that he could heal and regenerate was limited to several kilograms at most.
